CHAPTER 1DevelopingGoodStudyHabits

Youwouldn’t setup a deskinGrandCentralStationto studyforanexam.Nor would you invite your friendsto your room to hangoutwhile youpreparefor animportanttest.Butmanystudentsmightaswell. Theystudyin thenoisiest,mostdistractivesettingtheycanfind, oftenin frontof theTVor onthecouchwith thestereoblasting.

Somestudentsarguethat theygetbetterresultsthatway. However,whentheir testsarereturned,the verdictis inescapable:Noise andotherforms of distractiondecreaseyour ability to concentrate.If you can’tconcentrate,it’s likely that you’re not learningmuch.

Getting good gradesin collegerequiresthat you studyin a quiet,distraction-freesetting.There’sa lot more to gettinggoodgradesthanpicking a goodspottostudy,though.You mustalsolearn1how togetintothehabitof studying,2 whenthebesttimeis foryou to study,3 howmuch time you shouldspendstudyingeachsubject,4 how to avoidprocrastination,and5 whentotakeyourbreaks.Thischaptercoverstheseandotherimportanttopicsthatwill helpyou improveyour studyhabits.Whenyou’vecompletedthechapter,takea momenttoreviewthesuggestionsgiven here,andmakea list of waysto improveyour studyskills.

T I P 1 s Study in a well-lighted, distraction-free environment.Quiet is the first requirementof an appropriatestudy spot.Selectarelativelynoiselessroomin yourhomeor library.Studyat a deskora tablewith a straight-backchair. Avoid sofasor easychairs;they ofteninvitesleepinessbecausethey’resocomfortableandrelaxing. Be certainthatthelocationis well lighted.A window lookingouton treesor a parkmightbesuitableif therearen’ttoomany distractionsthatwill drawyou awayfromyour books.Makesurethatyouhaveplenty of room to spreadout, too.Crampedquarterscancrampyour style. A good dictionaryandotherreferencebooksappropriateto thesubjectunderstudyshouldbewithinarm’sreach.Onceyou’veestablisheda suitablestudyspot,stickwith it.

T I P 2 Setaside a study time eachday.After you havesetup a placeto study,how areyou goingto pull yourselfawayfrom theTV or telephoneor friends?You’ll needwillpower, certainly, butestablishinganunbreakabledaily studytimemayhelp.Yourbestbet is to set asidea studyperiodeachnight, say from sevento teno’clockmoreon this later.Whentheclock strikesseven,it’s timetohit thebooks.Noexcuses.

T I P 3 es Reward yourself when you stick to your schedule.You mayfind that rewardshelp you stick to your schedule.If you like tojog, forexample,promiseyourselfa run after studying.Or, how aboutachocolatesundaeat the endof a studyperiod?If you’re a musicbuff, topoff theeveningby listeningto your favoriterecords.If you like to readorwatchTV, rewardyourselfwith a goodbook ora televisionprogram.

T I P 4 es Don’t skimp on study time.Many studentsfind it difficult tosit inoneplacefor very long.A three-hourstudysessionmay aswell bea three-yearjail sentence.To getgoodgrades,though,you havetodedicatesometimetostudying.Learningtakestime.

As a rule of thumb, mostteachersrecommendat leasttwo to threehoursof studypercredithourperweek.Therefore,if youaretakinga three-credit anthropologycourse,you shouldexpectto studyaboutsix to ninehoursperweek.

Rulesaremadetobebroken,however,andthisoneis noexception.Forsomeclasses,suchasscienceor math,youmay find it necessarytodevotefive hoursof studyfor eachcredithour.For others,anhourmay suffice.Apply theruleof thumb,butadjustit accordingtoyour needs.If you arehavingtroublewith a class,increasethestudytime. It will payoff in thelongrun.Besuretomakeyour adjustmentearlyon soyoudon’t fall behind.

Clearly,no two coursesare alike-norare any two students.Justbecausea friend getsby withonehourof studybeforean examdoesn’tmeanyoucan.Hemay havetakena similarcoursein highschoolor mayhavereada lot on thesubjector maysimply bea faster learner.

Chapter5 pointsout thatstudyingeachsubjecta little everynightwillgreatly improveyour retentionandwill helpyou avoid cramming-thesurestway tostressyourselfandforgetthemostinformationin theshortesttime.

T I P 5 es Train yourself to study more.If threeor four hoursof studyper dayseemslike aneternity to you, tryworking up to it gradually.Forexample,during thefirst week,pledgetostudyonehoureachnight.To makethis a little lesspainful,youcanbreakeachhour into twenty-minutestudysessionsfollowedby five- to ten-minutebreaks.An alarmclock mightbehelpful to keeptrackof thestudyperiods.Whenthealarmgoesoff, finishyour thoughtandtakea break.Dosomeexercises,or takea quick walk. Thiswill helpyou stayawake.Raidtherefrigerator,or listento somemusic.Whenyourbreakis over,sitdownfor anothertwentyminutes.After that session,you maywantto rewardyourselfwith a specialtreat.A mentalpaton thebackis alwaysa goodidea.

Soonyou will find thattwentyminutespassin a flash.You maywantto increaseyour studyperiodsto thirty or forty minutesfollowedby tenminutebreaksto clearyour headandrelaxyour musclesmoreon thislater.

Gradually,overa fewweeks,you canincreaseyour totalstudytimetotwo hoursa nightandthenthreeor four hours.You will beamazedat howquickly threehourspass.You will find thatlearningto concentrateonyourstudiesfor severalhoursat a timemay helpyou immenselylater in life.

In short,everyonehasa timewhenthemind ismostalert.Usethat timeto studyif you can.By studyingduring thesepeakperiods,you absorbthegreatestamountof informationin theshortesttime.

If you areuncertainwhenyour peakefficiencyoccurs,try keepingarecordof yourmentalalertnessfor a week.Fouror five timesa day,makea notationaboutyour mentalstateon a calendaror in a notebook.If youfadequickly afterdinner, it is bestto spendthat timerelaxing. If you aredrowsyfirst thingin themorningbutjoin the living by ten, schedulesomeof your studyingafter thathour.

Severalstudieshaveshownthatstudentsretainmoreinformationiftheirstudysessionis followed by sleep.A few hourscanelapse,but longperiodsbetweenstudyandsleeptendto erasefactsfrom your memory.This is why I recommendedtheseven-to-tenstudyperiodearlier in thechapter.

The key to successfulstudyis choosingthe mostefficienttime. Whystudyfor fourhourswith a brainthatis working at half its capacity,whena two-hoursessionat peakbrainefficiency will get thesamejob done?Hitting peakefficiencyhelpsfreeuptimefor otheractivities.

T I P 7 es Avoid procrastination.Nohumanviceis ascommonasprocrastination-puttingwork off untilanothertime. Unfortunately,procrastinatorsalwayspayfor this badhabit.In college,putting off studyingor termpapersusuallycreatespanicandstressandoftenresultsinpoorgrades.

Try your schedulefor a weekor two,thenmodify it asneeded.Keepyour schedulewith you at all timessothatif somethingcomesup,youcancheckyour commitments.If you decideto"blow off" a studyperiodfor agameof volleyball, say,scheduleanotherperiodto makeup for lost time.

T I P 9 es Make to-do lists eachday.To optimize the limited numberof hours availableto you eachday,considermakinga daily list of thingsto do.Eachmorningafteryou getoutof bed,jot downa list of the thingsyouwouldlike toaccomplishduringtheday.Ifindit helpfultobeginmylist at theendof thepreviousday.ThatwayI don’t forgetimportantobligations.Be sureto includeall of your classesand labs,errandsyou needto perform, and studyperiods.I’d evenrecommendschedulingentertainment,exercise,andrelaxationtime.Otherwise,it’s tooeasyto skiptheseimportantaspectsof life.

You may find it helpful to notetheactualtimeyou will spendin eachactivity. Your to-do list might takethe form of a schedule:

Breakfast 7:30-8:00Sociology 8:30-9:30Chemistry 9:30-10:30Study 10:30-11:30Lunch 11:30-12:30Study 12:30-1:30Chemistrylab 1:30-4:30Volleyball 4:30-5:30Dinner 5:30-6:30Studychemistry 7:30-9:30Studysociology 9:30-10:30

Thiskind of to-do list assistsyou in keepingon trackandmeetingallof your obligations.Alternatively, you may wanttoindicatejust thetimerequirementsfor eachactivity. On aSaturday,for example,your list mightlook like this:

anyone’sspirit. But how aboutonehour or forty minutes?That’s a littlemoremanageable.

You may find thatsettinganalarmclockor anykind of timer atthebeginningof your studysessionhelpsyou tobuckledown.With theclockticking away,you’ll feel theurgencyto study.

As notedearlier in the chapter,besureto rewardyourself.Whenyoucrosssomethingoff your list of thingsto do,congratulateyourself.Whenyou aredonewith thewholelist, treatyourselfto a gameof racquetball,adip in thepool, a soft drink, or a favoriteTV show.

Whatdoyou do whenyou stop?Perhapsthebestwayof restoringyourmentalacuitysharpnessis to exercise.Two minutesof runningin place,jumpingjacks,or aerobicsareoftenenoughto awakenyou.Try this for aweekaftereachstudysessionto seeif it increasesyour efficiency.

If you arenot favorably disposedto exercise,you may find studybreaksa perfecttimeto do householdchores:washingdishes,laundry,orcleaningup aroundthehouse.Whateveryou do, though,getyour limbsmoving. If youcan’tseemto wardoff mentalfatigue,youmight considera shortnap.

CHAPTER 2SharpeningYour Memory

Memoryis a funny thing. Somepeopleseemtobeendowedwith a goodmemory,andothers...well. . .let’sjustsaythey’renotsolucky. Forstudentswithpoormemories,factsareoftenelusive.Lecturematerialgoesin oneearandouttheother.For them,life canbea frustratingordeal.Collegecanbea nightmare.

Fortunately,it doesn’thaveto bethis way. Memoryis like a muscle:Themoreyou useit anddevelopit, themorepowerfulit gets.Thischapterdiscussesa three-stepmethodfor sharpeningyour memory.

T I P 1 Practiceself-affirmation.Why isit thatsomepeoplecanrememberfacts,dates,anddefinitionswithcomputerlikeprecision,while othersstruggleto remembertheir ownphonenumbers?Is it becausesomepeopleare smarterthanothers?Perhaps.In manycases,though,certainpeopleseemsmarterthanotherssimply becausetheyknow howtorememberthingsbetter.In otherwords,they havedevelopedusefulskills thathelp them remember.

Equally important,they’veprobablydevelopeda winningattitude:Theyknowtheycanremember,andtheywant toremember.In contrast,youmaybetrappedin a self-fulfilling cycle:"I can’tremember.I havea rottenmemory.I don’t wantto remember.I won’t remember."

Thosedaysmustcometo anend.You canremember.You havethepotentialtohavea goodmemory.If youwanttorememberthings,youcan.Tell yourselfthesethingsoverandoveragain.

This technique,calledself-affirmation, is a way of changingyourattitudeandbuilding confidence.It canhelpyoubreakdownsomeof thewalls thatpreventyou from realizingyour full potential.By gettingrid oftheold messages"I can’tremember",you freeupyour mind toperformoneof the functionsit’s designedtoperform-storinginformation.

T I P 2 es Practicethe PMC method.Developingyour full memorypotential will taketimeandsomepractice,butit’s well worth the effort. Persistencewill payoff handsomely.

The techniquepresentedin this chapterisone of myown devising.Itinvolvesthreesteps:1 payingattention,2 makinginformationmemorable,and3 correlatingnewfactsandconceptswith thingsyou alreadyknow.I call it the PMC method.Canyou guesswhy?

T I P 3 es- Payattention.Many of usgo throughlife in a daze:daydreaming,taking in thesights,listeningto musicwhile theworldgoesby. Wepayonly marginalattentionto our environment.In manyrespects,our mindsarein neutral.

To improveyour memory,you mustfirst getoutof thisbadhabit.Youmustlearnto payattentionto theworld aroundyou.You mustactivateyourmind, andwhenyou doyou’ll find that yourmindwill beginto fill upwith interestingfactsandconcepts.

In theclassroom,payingattentionmeansjustwhatit says.You cannotsit in a classroom,gazingoutthewindow andthinking aboutlastnight’sdate,andexpecttogetmuchoutof thelecture.Sit up straight,takenotes,andkeepyourmind on thetopic.Sometimesit evenpaysnot tolookat thespeaker.Annoyingmannerisms,unusualdress,andunruly hair candistractyou.Don’t let yourmind besnaredby thedistraction.If youfind yourattentionwandering,try lookingaway.Watchtheboard,orkeepyour eyeson yournotebook.Takemorenotes.You will be amazedhowmuchmoreyou hearif you payattention.

Anotherway to heightenyour level of attentionis to askyourselfquestionsbeforehand.You’ve no doubtnoticedthat long-standingquestions tend to linger in your mind like a hungry animal waiting to besatisfied.Whenthefact that answersyourquestionpresentsitself, themindgraspsit andrarely letsgo.

You canusethisnaturalphenomenontoyour advantage.Here’show:As notedearlierin thebook,mostprofessorshandouta syllabus,orcourseoutline,at thebeginningof thesemester.In a sense,thesyllabusis a roadmapofthecourse.To makethemostuseof it, consultit beforeeverylectureto determinethe topic of discussion.Or, ask the professoror a fellowstudentwhatthe topicofthedaywill be.After you find out, pausefor afewminutesto think up somequestionsaboutit.

As anexample,supposeyourlectureisoncellularenergyproduction.Stopandthink aboutit. Whatquestionscometo mind?

1. Wheredoesa cell produceenergy?2. Do all cellsmakeenergy?3. Whatisenergy?4. Whatdo cells makeenergyfrom?

Theseimportantquestionswill probablybeansweredduring the lecture.You’ll retainthenew information moreeasily if your mind is primedbeforehand.

After you formulateyourquestions,stopfor a momentto reviewwhatyou alreadyknow.In otherwords,activateyour memory.Pull outfactsyou’ve learnedin otherclasses.Get thewheelsturning.

Payingattention,therefore,involvesatleastthreechangesinbehavior: attentivenessin class,posingquestions,andreviewingwhat youalreadyknow.Thesesimplestepsputthemind in gear.

You canusethesetechniquesto improveyour readingskills as well.For instance,beforeyou beginto readanassignedarticleor a chapterinyour textbook,takea momentto questionwhatis goingtobecovered,then

reviewwhatyou alreadyknow moreon this inChapter4.Thefew secondsit will takewill payhugedividendsin thelongrun.

To begin, look at the title of the articleand note the questionsitsuggests.Supposethetitle is "Symbolismofe.e.cummings’poetry." Whatquestionscometo mind?

1. Who ise.e.cummings?2. Whatis symbolism?3. Whendid thepoetlive?4. Whatwashis favoritesubjectmatter?5. Is hea British or anAmericanpoet?

Next,look at thesubheadingsandaska few questionsabouteachone.Photographs,drawings,andgraphsin thereadingmaterialalsobearsomestudy.Readthe legends,andaska few questionsabouteach.You mayfindit helpful to jot downyour questions.

After questioning,reviewwhatyou know aboutthesubject.Maybeyouhavealreadyread a poemby e.e.cummings.Whatdo yourememberabout it? Takefive to ten minutesto questionand review, then beginreading.Not all of yourquestionswill beansweredall of thetime, andnewfactsfor which you didn’t havequestionswill come up. That’s to beexpected.

T I P 4 es Find ways to make information memorable.Payingattentionmeansputtingyour mind in gear.Making informationmemorable,step2 of the PMC method,meansdoing somethingto makewhatyou learnstickwithyou. It’s a wayof makingthingshardertoforget.You canusea varietyof techniquestomakethingsstick inyour memory.Forexample:

RepetitionMnemonics:initialsandwordsPoems,lyrics, andmemorablesayingsWordrelationsRootsandoriginsof wordsPicturesanddiagrams

Unfortunately,memorydevicesfail from timeto time. Whatdoesn’t?However,the moreattentionyou give to creatingthem and the morepracticeyou getwith them,themorereliablethey’ll become.

Repetition.Forsomepeople,repeatinga newfactsilentlyorout loudwillsuffice tomakeit linger inmemory.Try this. Whenyouwanttoremembersomething,sayit toyourselfor sayitout loud. Supposeyoumeetsomeoneandwanttorememberhername.Onewayis to repeatit severaltimesin theconversation."Hello, Natasha.How areyou?Natashaisa prettyname.Isit Russian?I’ve nevermet a womannamedNatasha."Later,whenyouleave,repeatthenameonelast time. "So long, Natasha.Give mea call."

You cando thesamewhenyou read,study,or takenotes.If yourprofessorintroducesa newterm,write it downandsayit severaltimestoyourself. Do thesamewhenyou arestudying.

Mnemonics:initials andwords.Themindsometimesneedsa little extraassistance,especiallywhenfacedwith a lot of new information.Othertricks canbe used.Oneof thoseismnemonics.Mnemonicsarememorydevices-tricksthat help you remember.Suppose,for instance,yourenvironmentalscienceteacher tells you that the key to building asustainablesocietylies in five principles:conservation,recycling,renewableresources,restoration,andpopulationcontrol.How canyourememberall of this?Onewayis totakethefirst letterof everywordand form,ifyoucan,anotherword. In thiscase,you areoutof luck.You comeupwithCRRRP,butthatmay notbeenoughto jog your memory.Alternatively,you might think of thewordcarp.

Thephrase"Matt Hill, V.P." may bemeaninglessto you, but to abiochemistrystudent,it representsthe first lettersof the tenessentialamino acidsmethionine,argiine,threonine,tryptophan,histidine,isoleucine,leucine,lysine,valine,andphenylalanine.

This techniquecanbeusedin thesciences,wherelonglists of factsmustoftenbecommittedto memory.It canalsobeusedin thehumanities-for example,to remembera list of Romanticpoetsor countriesthatexportrubber.Thenexttimeyou havetorememberalist of items,try usingtheir initials to makea wordandseehow muchfasterit isthanjust plainmemorizing.

Poems,lyrics, andmemorablesayings.Poems,lyrics, andmemorablesayingscanalsobeusedto log informationin your brain. Considerthisphrase:"Thesimplewayto rememberChuck,if the tank’stoohotyou’reoutof luck." It may soundlike nonsenseto you, but to a scubadivingstudentit’s a way of rememberingCharles’sLaw, which statesthatpressureincreaseswith temperature.Thus,leavinga full airtankon a hotbeachcouldbedisastrous."CharlesPit" might be aneasierreminder:Charles’sLaw saysthatpressureincreaseswith temperature.

Be creative.Takethewordsyou wanttorememberandmakea poemorsayingif you can.If this doesn’twork, try the initials. Goodteacherswillhelpby suggestingmnemonicsfor rememberingnewinformation.

Wordrelations.Mnemonicsarejust oneelementin your growingbagofmemorytricks.Wordrelationsis anotherimportantdevice.For instance,supposeyou want to rememberthat a high-pressuresystemrotatesclockwise,while a low-pressuresystemrotatescounterclockwise.How doyougo aboutthis?It’s easy.Thinkof your kitchen.High on thewall istheclock. Below it, thecounter.Whatcouldbeeasier?A high-pressuresystemrotatesclockwise,and a low-pressuresystemrotatescounterclockwise.

Rootsand origins of words. Breaking words apart into their roots, suffixes,andprefixesoftenhelpstojogthememory.Forexample,a chemistrystudenttryingtolearnthe termexothermicreactionscanbreakthe first word

into itsparts.Ex meansfrom, andthermicmeansheat.Exothermicreactions,then,arethosethatgive off heat.Try breakingapartnewtermsthatyou wantto learn.A few secondswith the dictionarycanlock a wordpermanentlyintoyour memory.

Sometimestheoriginsof wordsare sointerestingthat theyhelpyourecallwhatthewordmeans.Theword comet,forexample,comesfromtheGreekwordmeaninghair. Energyfrom thesunpushesa comet’sgasanddustawaytoforma luminouswhitetail thatlookslikehair. Sanguinecomesfrom theLatin word forblood. In English, sanguinemeans"bloodred."Theword towdryisa contractionof St.Audrey,a cheapandshowydresser.

Takea fewsecondswhenyouencountera newterm.Breakit aparttoseeif youcanmakesenseoutof it. If thatdoesn’thelp,andit won’t always,look upthewordin thedictionaryto searchoutitsorigins.

Picti.tresanddiagrams.Otheruseful tools thatcanhelpyou rememberinformation,especiallyprocessesandrelationships,arepicturesanddiagrams.Drawingpicturesis anespeciallyusefulway to learnstructuresofcells or partsof the body. Drawingsanddiagramsareoften easiertorememberthan just plain words.Onevery useful tool for organizingmaterialis theconceptmap,which isdiscussedin Chapter3.

T I P 5 es Correlate new facts and conceptswith previousknowledge.Payingattention,step I of thePMC method,meansputtingyour mindingear.Making theinformationmemorable,step2, meansworking to makefactsandconceptsstickinyourmemory.Step3 involvesefforts tocorrelatenewfactsandconceptswith the informationyoualreadyknow andto tienewfactsandconceptstogetherto createa cohesivewhole.

Correlationmeanstying things together-makingsenseof the bitsand piecesof information you arelearningand havelearnedin othercourses.Insteadof beingcontentwith a mindfull of factsandconcepts,takea fewmomentsto seewhattheymean.Thisstepaloneoftenmakesthedifferencebetweena B studentandanA student.Correlationis usefulinall aspectsof study,especiallyin reviewinglectureorreadingnotesasyoupreparefor a test.

How doyougo aboutcorrelatingtheinformationyou’re learningwithwhatyou’vealreadyencounteredin your life? Theansweris simple:bytaking a few minutesto searchyour memory for related information.Suppose,for example,thatyou readthatyoungchildrenwhoseparentssmokesuffer twice thenumberofupperrespiratoryinfectionsas childrenwhoseparentsrefrain from this habit. Takea momentto think aboutfriendsandrelatives.Did anyof theirparentssmoke?Did theysuffer fromanincreasednumberof colds?

You canalsocorrelatewith other factsabout lung disease.Forinstance,you might recall from a previousclassthat childrenare moresusceptibleto pollutantsthanadultsarebecausethey tend to breathedeeperthey’regenerallymoreactive.This might explainwhy theyaresusceptibleto pollution from theirparents’cigarettes.

Besidesrelatingwhatyou’relearningtopastlessons,correlationalsoinvolvesa concertedeffort topieceall thenewfactstogetherto createanunderstandingof thewhole.In otherwords,it involvesstepsto assemblethe big picture.Themostsuccessfulstudentsdo it regularly.Graduatestudents,law students,andmedicalstudents,for example,will havearoughtimein schoolif theyjust cramfactsinto their heads.

Here’sa suggestionfor assemblingthebig picture:After studyingasectionof your notesor readinga chapterin your book,summarizeit inyour own words,usingthefollowing guide:

1. Whatarethemainpoints?2. How hastheauthorsupportedthesepoints?3. Whatnewfactsdid I learn?4. In whatareashasmyexistingknowledgedeepened?5. Whatdoesthis informationmean?6. How canIuseit?

Youcanassemblethebigpicturein theshoweror onyourwayto andfrom classes.Havea good talk withyourselfas you hike or ski or swim.Imagineyourselfin frontof a classroom,explainingtheinformationyoujust learned.

Not only doescorrelatingfacts tie information together,but it alsohelpskeepyourmind active,andit makesinformationtrulymorememorable.It hasanotherbenefitof greatimportance:It helpsyou becomeathinkeras well asa memorizer.

CHAPTER 3Getting theMost Out ofLecturesandLabs

Lecturesare thebackboneof a collegeeducation.Gettingthemostoutoflecturesrequiresstudentstobegoodnotetakers.In fact,exemplarynote-takingskills areessentialtosuccessincollegebecausemanyprofessorstestfrom theirlecturematerial,askingfewquestionsfrom thetextbookreadings theyassign.Note taking also helpsstudentskeeptheir attentionfocused,preventingthemind from drifting off to farawayplacesor todistractionsin theclassroom.

Thegoal of note taking during a lectureis simply this: to createalegible,easy-to-followsummaryof yourprofessor’stalk. Easyasthatmaysound,it takesa certain skill and a lot of practiceto takegood notes,especiallyin scienceclasses,whereteachersoftenusea varietyof visualaids-suchasoverheadtransparenciesandslides-tosupplementtheirlectures.

To understandthecomplexityof the taskathand,considerwhatgoesonin a lecture.First,you mustlistenandunderstandwhatisbeing said.You mustthenanalyzetheinformation,thoughthepaceof manylecturersleavesfar too little timetothink aboutwhatis being said.Next,youmustsort throughtheincomingmaterial,selectingwhatyou wantto write inyour notes.Finally, you mustjot the informationdownquickly soas notto missthenextpoint. That’sa lot of brainwork andhandworkin quicksuccession.With somehelpful tips,though,you will find that thetaskisdoable.

Laboratoriespresenttheir own challenges.Thesestructuredlearningenvironmentsrequire studentsto do most of the work. With a littleguidance,though,you canexcelin labwork andgetgoodgradesforyoureffort.

T I P 1 e.Know the subjectof each lecture before youwalkin the door.Many studentswalk intoalectureunawareof thetopicoftheday.if they’relucky, their professorwill devotea few minutesat thebeginningof thelectureto anoverview-thatis, listing the topicsthatwill be discussedduring the classperiod.Someprofessorswill evenwrite anoutlineon theboard.Unfortunately,mostprofessorssimply say,"Today,we’regoingtobetalkingaboutsuchandsuch,"andleaveit atthat.In thiscase,the lecturemayseemlike a disconnectedsetof facts, figures,concepts,and terms.

If your professordoesnotoffera daily outlineoftopics,youmight askhim or her to provideone.Otherwise,you mustdo thework yourself.

Beforeeachlecture,look up thetopic of the dayon your classschedule.Study the assignedchapteror readingmaterial.At the very least,thisentailsa few minutesof timespentlookingover themainheadingsandstudyingthekey words,tables,andfigures.You might alsowantto readthetopic sentencesof eachparagraph.Thisprocedurehelpsimmensely,ensuringthattheinformationyou hearin lecturewon’t betotallyforeign.While otherstudentsarelearninginformationfor thefirst time, you’ll hearwordsandconceptsthatarefamiliar toyou,helpingyou retainthemmoreeasily.Chapter4 discussesthistopic inmoredetail,outlininga strategytohelpyou previeweachreadingassignment.

Theimportantpointis that if your professorwon’t supplyyouwithanoutlineof eachday’s material,you mustlearnthetopic yourselfbeforeenteringthe class.While you’re at it, it is also helpful to spenda fewminutesbeforeeach classreflecting on anyfactsyou know aboutthesubjecttobediscussed-thatis, correlatingthenewinformationwithwhatyoualreadyknow.Spendsometimeaskingquestionsas well. Thisis partof thetechniquefor payingattentionthatis describedin Chapter2.

T I P 2 Spendsometime before each lecture readingprevious notes.Reviewingyour notesfrom previoussessionsbeforeeverylectureis auseful learning tool. It helpsyou keepup with the lecture material,reducingthe timeyou’ll needfor studylater on. It also helpsyou recallimportantfactsandconceptsthat maybealludedtoin the lecture.That is,it refreshesyour memory,reviving informationyou will beexpectedtoknow in order to understandnew concepts,facts,and terms.If you’reconscientiousaboutreviewinglecturenotes,it’s much less likely thatyou’ll feel lost. So,get to classa bit early, andspendfive to tenminutesquickly readingthroughyour notesfrom thepreviouslectureor two. Youwon’t besorryyou did.

T I P 3 Attend lecture regularly.This rule needslittle explanation.For many of us, learning requiresrepetition.Wemusthearandreadinformationa numberof timesfor it tosinkin. Lectureisoneof thosetimes.Study sessionsaremeantto fix factsandconceptsin your memory.If you don’t attendclassand takenotes,chancesareyou won’t getmuch outof thecourse-unless,of course,you’re a geniusorextremelyadeptat learningoutsideof class.

Importantasattendinglectureis, somestudentsskipclassfrequently,confidentthattheycanlearnthematerialfromotherpeople’snotesor fromthereadingassignment.Bearinmind, however,thatborrowednotesmaybefar from perfect.Theymaycoveronly 20 to50percentof whatwassaidin thelecture;importantinformationmaybemissing.In addition,thenotetakermayhavegotten factswrong.

T I P 4 es Write as legibly as you can.A surprisinglylargenumberof studentshavetroublereadingtheir ownlecturenoteswhenthey try tostudythemsometimelater.As a result,they

missimportantpoints,andtheirexamgradesusuallyreflectthis.Write aslegibly asyoucan. If yournotesarea mess,rewritethemortypethemthatsameday.

T I P 5 Study your noteswithin a few hours of each lecture, andfill in the missing information.If you decideto redoyour lecturenotes,usethat timeto studythem,asrecommendedinChapter5. In otherwords,don’t justcopythemmechanically; think aboutthem.Try to fix theinformationin yourmemory.

Besideshelpingyou to learnthematerialyou justencounteredinlecture,reviewingyournotesprovidesanopportunitytoadd informationthatwasmentionedin lecturebutthatyou failed to write down.To makethis processeasier,besuretoleaveextraspacewhenyou’retaking themthefirst time.

Evenif you don’t needtorewriteyournotes,it ishelpful tostudythemwithin a few hoursof lecture.Onetechniquethat’squite usefulis to try torecallwhatwassaidbeforelookingatyournotes.Runoverthemainpointsandwhateversupportinginformationyou canrecall, thenturn to yournotes.

Forcing yourselfto recall the information givenin a lectureclearlyhelpsyou rememberlecturematerialbetter.It canalso reduceoverallstudytime.Studiesshowthatyou will forget75 percentof whatwassaidin a lecturewithin oneweek if you haven’tforcedyourselfto recall it.Within threeweeks,98 percentof what was said in a lecturewill beforgotten.That’swhy it is soimportantto rewriteorstudyyour notesandfill in the missinginformationsoonafter a lecture.

T I P 6 Developa shorthand systemto reducewritingduringlecture.You canwastea lot of timein lecturewriting commonlyusedwordsandphrases.This laborioustask might causeyou to missimportantdetails.Becauseof this,I recommenddevelopinga shorthandsystemof yourown.Thiswill reducewriter’scrampandwill helpyou avoidmissingimportantinformation.Hereis a list of symbolsyou canusein manycourses:

Somestudentslike to savetimeby omitting thevowels of certainwords.Forexample:Omtvwls rdcswrtng tme. This systemtakessomepractice,but it cansavetime.

T I P 7 is- Don’t write down every word your professorsays.Afraid thatthey’ll missanimportantpoint,somestudentsinsiston writingdownvirtually everythingthe professorsays.Althoughverbatimtranscriptsof lecturesmayseemlike a goodidea,it hasits drawbacks.Forone,if thelecturertalksfasterthanyou write,youwill fall behindandmay missmanyimportantpoints.Second,with this techniqueyoubecomea parrot.Informationgenerallywon’t remainin your memoryunlessyou "own"it-thatis, unlessyou understandit andwriteit downin your ownwords.

Still, I recommenderringon the conservativeside-thatis, taking asmany notesas possible.Concentrateyour energyon writing down themajor pointsandany supportinginformationandexamples.Grasptheessentials,andleaveroom tofill insomeof thedetailswhenyoucopy andreviewyour noteslater.

T I P 8 is- Watch for signalsthat indicate important material.Most professorswantyou tosucceed.Theylovetheirsubjectandwantyouto learnit. Consequently,manyprofessorsgive usuallysubtle,sometimesobvious,signalsduring lecture to showyou what’simportant-what’sworthremembering.

Themostobviouscluesincludephrasessuchas"Thisis anextremelyimportantpoint" or "This would bea goodtestquestion!" Be awareofthesehints. *

Many professorsalso summarizekey pointson theboardor on anoverheadprojector.Whentheystopto write, theyusuallydo soforoneoftwo reasons:1 It’s a difficult word or concept to spell, or 2 it’s anextremelyimportantconceptthat they wantyou to get it in your notes.Somestudentsonlywritewhattheprofessorwrites,butthat’snotenough.

T I P 9 is- Sit toward the front of the class.If atall possible,sit nearthe front of theclass.Thefartherbackyou are,themoredistractionsexist betweenyou and your professor.A snoozingstudent,talkingfriends,shuffling papers,andmany otherdistractionsdrawyour attentionawayfrom thelecture,makingyou missimportantpoints.

In classesin which studentsareseatedalphabeticallyby last name,youmayendup in a placethatdoesn’tsuityou. If you’re stuckin theback,askyour professorif you canmoveforward.If you explainthatyou findit toodistractiveto sitin thebackandreallywantto getthemostoutof thisimportantclass,your professormay find you a spotupfront.

Conceptmappingis also helpful when taking noteson readingmaterial.Somerecentcollegetextbooksand somestudy guidesthataccompanytextbookscontainconceptmaps.Nonetheless,I recommendthatyoudevelopyour own; thatway, you’ll organizethe informationinwaysthat makethemostsenseto you.Whenyou’re done,consulttheconceptmapsinyour studyguidetocompareyourorganizationwith theauthor’sandto seeif you’veomittedanyimportantconcepts,facts,orrelationships.

linebetweenpointA andpointB. Thatis tosay,moststudentsstartreadingatthebeginningandreadstraightthroughuntil they reachtheend.

Although this maywork for a novel,it’s a ratherinefficient way ofreadinga textbookor anarticle. In fact, the fastestandmostefficientwayof readingclassmaterialdoesnot follow a straightline.

Beforeyou plungeinto a readingassignment,previewthe material.Readthe title of thechapteror articlefirst. Study the main headings.Nowadays,many textsincludechapteroutlinesat thebeginningof eachchapterthatpermityou to previewthematerialat a glance.

Thepurposeof previewingis to seehow the materialin thereadingassignmentis organized.Thishelpsyou setup logical categoriesinwhichtoplacethenewinformationyou areabouttolearn.Moreover,previewingshowshowimportantconceptsarerelated.

Consideranexample.Chapter2 of ahealthbook calledLTeChoicesbyEleanorNossSizerandFrancisSienkiewiczWhitney Brooks/ColePublishing Companycontainsthefollowing main topics:

SensorsandStressBody Systems:Nervous,Hormonal,ImmuneSystemsTheStressResponseStressManagementStrategies

By lookingovertheheadings,you get a goodideaof how theauthorshaveorganizedthematerial.First, theytalk aboutsensorsandstress.Theythenlook at keybodysystemsthatareaffectedby stress.Next,they lookatthebody’sresponsetostress,andtheyconcludewithstressmanagementstrategies-thatis, waysto reducestress.As you readthechapter,youwilllearnmoreabouteachtopic.

SensorsandStressWhataresensors?Are theypartof the nervoussystem?Are specialsensorsinvolved in stress?Whatexactlyis stress?

Now it’s timefor anotherpreviewingfeat. It’s timeto readthefirstsentenceof eachparagraph.In mostnonfictionreadingsyou will encounter, thefirst sentenceof eachparagraphis usuallya topic sentencethatdescribesthesubjectof eachparagraphandisthereforetheauthor’ssignalto you. It is the authorwaving a flag and saying,"This is what theparagraphyou areaboutto readis all about."

T I P 5 es Previewtables and figures.After previewingthe main topicsof the chapter,askingquestions,andreadingthe topic sentences,you may wantto lookoverall of the illustrationsandtables.In well-writtentextbooks,theillustrationsusuallytell avivid story.

Therefore,write your own outlineafterreadingandstudyingeachassignment.List the mainconceptsand factsand then any importantsupportinginformation.Determineweakareasby comparingyouroutlineto thereadingassignment.Fill in thepointsyou missed.

Althoughoutliningmayseemlike a lot of work, it couldsaveyou timein thelongrun.Outlinesof readingmaterialandlecturenotesareexcellenttools forpreparingfor exams.

If yourinstructortestsheavilyon readingmaterialandexpectsyou tointegrateyour lecturenoteswith it, you will needto drawthetwo outlinestogether.In otherwords,you will needto transferinformationfrom yourreadingoutlinetoyour lectureoutline.If thisis thecase,leavesomeroomin yourlectureoutlinetoaddreadingmaterial.You maywanttohighlightreadingmaterialby usinga differentcolorpen or pencil.

With a little practice,you canlearnto writeanexamthat’s remarkablysimilar to theoneyour professorwill write. Following aresomesuggestionsthatwill makethis processeasierfor you.

First,determinethe kindsof questionsyour professorwill ask.Mostprofessorsarewilling to tell their studentsthetypesof questionsthey’llincludeon an upcomingtest. Many will actually give you a precisebreakdown-forexample,twenty pointsin essayquestions,fifty pointsinmultiple-choice,andthirty pointsin fill-in-the-blank.

Next,takea few minutesto look overyour lecturenotes,imaginingthatyou are a teachingassistantwho mustwrite thetestfor theclass.Asyou examineyour notes,look for information that lends itself to theassortmentof questionsyour professorhasindicatedwill beon thetest.Beon thelookoutforpotentialessay,fill-in-the-blank, multiple-choice,true-or-false,andmatchingquestions.

Essayquestionsprovidea way of testingyour understandingof asubject-thatis, how well you comprehendimportantprocessesandconceptsandhowwell youhavecorrelatedorassimilatedthefacts.If yourprofessoris fond of this type of question,takesometimeto look throughyour notesforbigblocks of informationthat lend themselvesto essays.

Long, detailedexplanationsof processesmakefor excellentessayquestions.If you are studyinga biological process,suchasevolution,forexample,you mightbe askedto writeanoverviewof theprocess.A essayquestionsuchas thiswill requireanywherefrom halfa dozento a dozenmainpoints.

Multiple-choicequestionsusuallyfocuson materialthathasthreetofourmainpoints.Look throughyournotes.Canyoufind subjectsthathavethreeor four supportingfacts? If so, turn them into multiple-choicequestions.Fill-in-the-blank,matching,and true-or-falsequestionsareusuallyusedfor testingknowledgeof termsandconcepts.

With a little practice,you canbecomeanexpertat second-guessingyour professor.But yourjob isn’t doneyet. A dayor two beforetheexam,take your own test. To savetime, don’t write out answersto essayquestions;simply list thekey pointsin a logical order.

CHAPTER 6Becominga CriticalThinker

Many peopleI knowstudieddiligentlyduringcollege,dutifully spewingoutfactsandfiguresfor tests.For themostpart, theyreceivedgoodgradesfor their hardwork. Despitetheir success,though,many of them nowcomplainthattheyactuallygotlittle outof theircollegeyears.Thatis, theydidn’t learnverymuchfor all thetimetheyspentin class.

Thecomedianbehind FatherGuido Sarducciof "SaturdayNightLive" fameinventedtheFive-MinuteUniversityas a symbolicjab atoureducationalsystem.For$25,his facultyteachesstudentseverythingtheywill remembertwo yearsaftergraduation.Theentirecurriculumtakesfive minutes.

Unfortunately,thecomedianisn’t far from thetruth.Many studentsand theirparentsspendtensof thousandsof dollarson a collegeeducation, butforwhat?A few vaguememories?

While we’re quick to blameteachers,a lot of thefault may lie inourselvesfor not really learninginformation in thefirst place. In fact,many peoplewho feel shortchangedby their collegeexperiencecouldhaveavoidedthis disappointmentby practicingthePMC methodthisstrategyfor increasingmemoryis presentedinChapter2. Spacedstudying andmanyothertechniquesdiscussedinpreviouschapterswouldalsohavehelpedthemretainmore.

Collegesand universitiesare also frequentlycriticized for theirfailureto promotethinking.I’ve heardmanystudentscomplainthattheyarejustbeingaskedtospitbackfacts.Theblamefor this canbepinnedonprofessorswhodon’t encourageassimilationandthoughtfulanalysis,butit falls on students’shouldersaswell.After all, studentsshouldbeactiveparticipantsin the learningprocessandmustacceptsomeresponsibilityfor learningto thinking.

Learningtothinkis a threefoldchallenge.First,it requiresfacts. Youcan’tthink very well if you don’t know anything.Second,it requirescorrelation,which is discussedin earlierchapters.By correlatingfactswithpreviousinformationandseeinghowfactsfit togethertoform thebigpicture,you becomea deeper,betterthinker.But correlatingfactsisnotenough.To becomea realthinker,you mustalsolearnto think critically.to provetheir case.This leadsto thenext recommendationfor criticalthinking.

Critical thinking meansmanythingstomanypeople.I defineit asthecapacityto distinguishbetweenfactsandbeliefsor opinions.In otherwords,critical thinking allows you to distinguishbetweenwell-estab

lishedfactsandpeople’sjudgments,whichareoftentaintedby valuesorpreconceivednotions.

Critical-thinkingskills helpyou analyzeproblems,issues,andinformation.Theyhelpyoudeterminetheaccuracyofinformationpresentedtoyouandavoid illogical thinking andothermistakesin reasoning.Critical-thinking skills will allow you to drawsoundconclusionsfrom factualinformation,and theymakeyou less likely to beswayedby emotionalarguments.You will no longerfall prey to themerelyeloquent-thoseskillful verbalmanipulatorswho could sell realestateonthemoon.

Critical thinking is as essentialto your intellectualdevelopmentasgoodfood isto propernutrition.If you’re headingfor a careerin anyoneof dozensof fields,suchasbusiness,law,medicine,science,engineering,oreducation,critical-thinkingskills will beessential.Without them,you’llalwaysbeat a disadvantage.

T I P 1 ?s Becomean active participant.Oneof thefirst requirementsof critical thinking is thatyou takeanactivepartin acquiringinformation.Don’t sitbackandaccepteverythingyoureadandhear.Questionwhatyou learn,andseekothersources.

T I P 2 es Understand all terms.As you study,you will encountermanynewterms.Theyarethebricksinthefoundationof yourunderstandingof varioussubjects.Withouta cleardefinitionof newterms,you will beunabletomastera subject,andyouwillbeincapableof thinking clearlyandcritically.

Understandingtermsandmakingsurethatothersdefinetermswhentheytalk withyou will help bring clarity to conversations.In fact,manyargumentsturnon a failureof oneorbothparticipantsto understandthespecificmeaningof wordsthat arebeing used.TheGreekphilosopherSocratesdestroyedmany argumentsin his timeby insistingon cleardefinitionsof terms.You canbecomea critical thinker by alwaysbeingcertainthatyou understandthespecificlanguageof your subject.

T I P 3 es Question the methodsby which facts were derived.In attemptingto sort facts from judgments,it is importantto determinehow thefactsbeing presentedto you werederived.Did they comefromscientificexperiments,or werethey derivedfrom random,unscientificobservations?

A properexperimentin thebiological sciencesandmedicinetypicallyinvolvestwo groups:anexperimentalgroupand a control group.Theexperimentalgroupis theonethat is manipulated;thecontrol groupistreatedthesameway ineveryrespectexceptthatit isnotmanipulated.Forexample,totesttheeffectof excessvitaminingestion,a researchermightstartwith two groupsof people.In a goodexperiment,bothgroupswouldbeas similaras possiblein age,sex,weight,race,andsoon.Both groupswould betreatedthe samethroughouttheexperiment.They would,forexample,receivethesamediet andwould behousedin thesamefacility.

Ideally, theywouldbeexposedtothesamelevelsofstressandwouldworkandrestequally.In a well-runexperiment,theonly differencein thetwogroupswould be the vitamin supplementsgiven to the experimentalgroup.Any observeddifferencesbetweenthegroups,therefore,canbeattributedto the treatment.

Goodexperimentsrequireanadequatenumberof experimentalandcontrolsubjectsto besurethatanyobserveddifferencesarereal.In manylaboratoryexperiments,at leasttentestanimalsarerequired.More thanten is evenbetter.For humanhealthstudies,much larger groupsaregenerallyused.

Thus,whenassessingthevalidity of informationbeingpresentedtoyou, find out if thestudywasadequatelyperformed.Did theexperimenthavea controlgroup?Werethecontrolandexperimentalgroupstreatedidenticallyexceptfor theexperimentalvariable?Did theresearchersuseanadequatenumberof subjects?

In science,oneexperimentis rarelyadequateto drawfirm conclusions.Thus,cautionis advisedwhentheresultsof newexperimentsareannounced.Themediaare especiallyfond of publishingtheresultsandconclusionsof new studies,but suchreportsshouldbe viewed withconsiderablecaution.Follow-up studiesoftenpresentcontradictoryresults.

To ensureconfidencein the conclusionsof a newstudy, theexperimentshouldberepeatedby otherresearchers.If similar resultsare obtained,youcanbemoreconfidentin theconclusions.

T I P 4 es Question theconclusionsderived from facts.Whenanalyzingany issue,argument,or scientific finding, it isimportanttodetermineif the factssupporttheconclusionsbeingmade.Ask yourselfif whatyou’re hearingis really true.Are therealternativeexplanations?

Consideranexample.Oneof the first scientificstudieson thecausesof lungcancerrevealedthatpeoplewho atelargeamountsof whitesugarsucrosehada higherincidenceof lungcancerthanthosewhoconsumedsmallerquantitiesof sugar.Theresearchersconcludedthatsugarcausedlungcancer.

A carefulreexaminationof thepatients,however,showedthat therelationshipbetweencauseandeffectin this experimentwasnot whatresearchershadoriginally thought.Uponreexamination,theresearchersfound that smokerstendedto consumemoresugarthannonsmokers.Thus,a moreprobablecauseof lung cancerwassmoking,not sugarconsumption.

Thisexampleillustratesa key principleof medicalresearch:Correlation doesn’tnecessarilymeancausation.In otherwords,two factorsthatappearto beconnectedmay notbecausallyrelated.

Anotherexampleillustratestheimportanceof thisrule. In 1989, U.S.physiciansreportedthatsomeof their patientsweresuddenlybecomingill. Whenhealthofficials at theCentersforDiseaseControllookedintotheproblem,they foundthattheaffectedindividualshadbeeningestinglargedosesof L-tryptophan,anaminoacidavailableinpill form in mosthealth-

food stores.L-tryptophanpresumablyhelpssomepeopleget tosleepandis believedto easethesymptomsof premenstrualsyndromein somewomen.

Within a short period, physiciansdocumentedmore than twelvehundredcasesof L-tryptophan"poisoning."Somevictims died; manyothersbecameparalyzedor were severelyimpaired. Becauseof theseverityof the problems,L-tryptophanwasquickly takenoff themarket.Further researchhasshown,however,that the culprit in this tragicincidentwasnotL-tryptophan,buta chemicalcontaminantfoundin thepills. As in thelung cancerexample,thecausewasincorrectlyassigned.

Conclusionsmayalsobebasedon inaccuratedata.In someinstances,apersonmaybaseanargumenton datathatheorshebelievesaretruebutin factarenot.In others,a personmaybaseanargumenton anoutrightlie.Watchfor suchinstances.They’resurprisinglycommon.

Anotherpitfall to watchfor is theselectiveinclusionor exclusionofdata.Many peoplebecome"one-study"experts.Theylearnonefactor afew factsandthenbaseentireargumentson this limited baseof knowledge.In sodoing,theymayomit a wealthof informationthatcontradictstheir case.In addition,a lot of peopleseekoutfactsthatsupporttheirpointsofview; theymakeuptheir mindsandthenseekto provetheircase.This leadsto thenext recommendationfor criticalthinking.

T I P 5 es Look for hidden assumptionsand bias.Anothersurprisinglycommonproblemwith theconclusionssomepeopledrawisthat theyareofteninfluencedby incorrectassumptionsandbias.Critical thinking requiresthatyou uncoverassumptionsandbiasesthatunderlietheconclusionsof others.

Considerthefollowing exampleof anunderlyingassumption.Manypeoplebelievethatall radiationexposureisdeleteriousto humanhealth.Is this conclusionbasedon anyunderlyingassumptions?Is it valid?Theconclusionis basedon a belief that thereis no safe thresholdlevel forradiation-thatis, a level below which no harmoccurs-andthat, as aresult, all exposureis dangerous.Scientists,however,still debatethisassumption.Someclaim that thereis a safe thresholdlevel. Thus,theconclusionthat all radiationis harmfulis notuniversallyaccepted.

T I P 6 es Questionthe sourceof facts.Beingon thelookoutfor biasanddeceitforcesyou to questionthesourceof information.Bewareespeciallyof "experts."Salespeoplearenotoriousfor passingthemselvesoff as expertson a wide rangeof subjects,fromhomeheatingtonutrition.Often,however,thesepeoplearepresentingalimited subsetof factsthat supporttheir point of view and sell theirproduct.

Thisruleappliesto more thanjust salespeople.It appliesaswell tovenerableprofessionals-evenphysicians.Forexample,considerwithskepticismthenutritionaladviceyou receivefroma physician.Shouldyoucountonit? Most physiciansin practicetodayhavereceivedlittle, if any,formal training in nutrition. In the seventies,a studyof hospitalpatients

showedthatmany whowereundera doctor’scareforprolongedperiodssufferedseveremalnutrition.Althoughthisstudyresultedin a dramaticreanalysisof nutritional instructionin medicalschools,a studyof U.S.medicalschoolsin themid-eightiesshowedthatnutrition trainingwasstillwoefully inadequatein many schools.Eventoday, apparently,manymedicalstudentsgraduatewithouta soundunderstandingof therole ofnutritionin preventingdiseaseandpromotinggoodhealth.

T I P 7 es Don’t expectall theanswers.Ironically, critical thinking requiresa tolerancefor a certainamountofambiguity.Ambiguityexistsin all fieldsof study.Thatisto say,hard-and-fast answersare not always available.As a result,you mustbecomecomfortablewith uncertainty.

Forexample,manycredibleatmosphericscientistsbelievethat thesurfacetemperatureof theEarthis increasingasa resultof thebuildupofcarbondioxideandothergasesfrom a wideassortmentof humanactivitiesoverthepasttwo hundredyears.In fact, manyof thesescientistsarewillingto staketheir reputationson this conclusion,and they canquote animpressivebody of informationin supportof their view.

Not all scientistsagree,however.A smallnumberbelievethatprojectionsof global warming are wrong.Theyarguethat otherfactorsmayreducewarmingor mayeliminateit altogether.Globalwarmingis therefore an issueaboutwhich critical thinkers might reserveopinion. Butbeforeyou closethebook on thesubject,readon.

T I P 8 es Examine the big picture.If it materializes,global warmingcould resultin a dramaticshift in worldclimatethatcouldturnproductivefarmlandtodesertandcouldeventuallyflood 20 percentof theworld’s landmassasglaciersandtheAntarctic icecapmelt. It couldhavedevastatingeffectson plantandanimallife. Becauseof this, critical thinkersmight chooseto takeaction despitethescientificuncertainty.That is,destroyingtheclimateofa planetposessucha seriousthreatthat stepsto eliminatetheproblem maybe the most intelligentchoice,evenif wearenot 100 percentcertainthat thereisa problem.

Thethreatof global warmingcanbe reducedby markedimprovementsin energyefficiencyin automobiles,factories,andevenour ownhomes.Somethink of this asa kindof insurancepolicy thathastheaddedbenefitof reducingurbanair pollution,stretchinglimited suppliesof oilandotherfuels,andsavingsubstantialamountsof money.

Consideranotherexampleof thebenefitsofexaminingthebigpicture.In 1988, researchersat Monsantoannouncedthat theyhaddiscoveredawayto alterthegeneticmaterialof wheatto makeit resistantto a fungusthatcausesenormouscropdamage.Farmerscurrentlycontrol thefungusby rotatingcrops-thatis,plantingwheatoneyearandanothercropthatdoesnotsupportthepestthenextyear.Thenewgeneticallyalteredstrain,however,would eliminate theneedto rotatecrops,allowing farmerstoplanttheir fields in wheatyearafteryear.It would evenallow farmerstoplant largercrops.

Althoughthismaysoundlike agreatidea,critical thinking showsthatit couldbeaninvitation to disaster.Why?

First, croprotation helpsbuild soil fertility. Rotatingbeans,clover,alfalfa, andother legumeswith wheat,for example,addsnitrogento thesoil andhelpsmaintainsoil fertility. Not rotatingcropsoftendrainsa soilof itsnutrients,reducingits long-termproductivity.

Second,crop rotationhelpsreduceinsectpests.By plantinga newcrop in a field everyyear,farmersreducefood sourcesfor insectsthatpreferonecropoveranother.Becausethefood supplyisnotconstantfromone year to the next,pest populationsremainlow and manageable.Eliminating croprotation may result in repeatedoutbreaksof harmfulwheat-eatinginsects.

In solvingthe fungusproblem,then,sciencemaycontributetoseveralotherproblems.The lessonin this caseisthat a carefulexaminationof theecologicalrelationshipsthebig pictureoftenthrowsinto questiontheapparentwisdomof newactions.

T I P 9 e Examine multiple causeand effect.This rule isanextensionof the previousrule,examinethebig picture.Asintelligentashumanscanbe,wearealsooftenrathernarrow-minded.Wefall backonsimplisticthinkingwith surprisingfrequency.In theseventies,for instance,PaulEhrlich, a notedecologist,arguedvigorouslythat theworld’s environmentalproblemsstemmedfrom overpopulation-toomanypeoplefor theavailableresources.Anotherequallyreputableanddistinguishedscientist,BarryCommoner,arguedthattheproblemsweredueto technologyandits by-product-pollution.

A morecarefulanalysissuggeststhat theenvironmentalproblemsthattheUnitedStatesfacesarecausedby numerousunderlyingfactors.Inotherwords,overpopulationandtechnologyare just two of manyrootcauses.Inadequatelaws andpooreducationmustbefactoredinto theequation,asmustvariouspsychologicalfactors-forinstance,ourviewoftheworld assomethingtoconquer.Many morecouldbeaddedto thelist.

Critical thinking clearlydemandsa broaderview of causeandeffect.It demandsthatyou considerall of thecontributingfactorsand theirrelativecontributionsto the problem.It forcesyou to avoid simplisticthinking, whichoftenleadsto simplesolutionsthatfail miserably.

Oneform of simplisticthinking is calleddualisticthinking.Dualisticthinking is thatwhich acceptsonly two viewpoints.It’s black-or-white,right-or-wrongreasoning.Presentinga personwith only two choiceswhentherearemanyis calleda falsedichotomy.It shouldbea signaltoacriticalthinkerto lookdeeper.Whenpresentedwith onlytwo alternatives,look for a third or a fourth.They’reoftenthere,andthey’re oftenvalid.

It’s truethatindividual actionsdon’tamounttomuch,butwhenaddedtogether,theycanbecomemeaningful.After all, manyofour problemsarethe resultof thecumulativeeffectof individualactions-carelessnessandwaste.If they createour problems,theycanalsobepartof thesolution.

T I P 11 esBewareof labels.Labelsareconvenienttagsthathelpusorganizetheworld aroundus,buttheycanbemisleading.Foronething, theyareofteninaccurateor,atbest,maybe a partialtruth. Labelsare commonin thepolitical arena,whereindividualsareoftenlabeledas"liberals" or"conservatives."In reality, apersonmight beliberal on someissuesandmoreconservativeon others.Labelingthatpersonasa liberal thusmissesthetruebreadthof hisorherviews.In theenvironmentalarena,a liberal is onewho seeksto preserveopenspacesandprotecttheenvironment.Isn’t that really a conservativeoutlook?
