  • 3. Methods: Putting theories and models togetherAdapted from Romiszowski, 1984

  • 3.1 Methods: How do you think? The Block Problem: Visualisation Draw a pictureMathematically How did you do it? Were you successful on the first or second attempt? Did you use more than one strategy? (ie. Visualise and deduce that blocks have eight corners)

  • 3.1 Methods: How do you think? The Sticks Problem: Visualising Drawing Manipulating Objects

    If you manipulate objects: Be aware of how it feels to do solve the problem this way. Are you carrying on a verbal dialogue (verbalizing)? .

  • 3.1 Methods: How do you think? The Who Did It problem: In this problem only one statement is true. Determine from the information given who did it? A said, "B did it." B said, "D did it." C said, "I did not do it." D said, "B lied when he said I did it." Verbal/Logical solution

    Easy to confuse the information statement with the problem statement: Many learners try to figure out which statement is a true, rather than which person is guilty.

  • 3.1 Methods: How do you think? The Who Did It problem continued:

    Begin by assuming A is guilty, determine if it is the case that only one statement is true, then assume B is guilty, and so on until you find that only one statement is true. (This method is most common for those who do solve the problem, and will result in a correct answer) If you noticed that since only one statement is true and C says that he didn't do it, one need only discover that one of A, B, or D is telling the truth to establish that C is guilty (if A, B, or D is true, C is false; thus C did it). Since B and D contradict each other, only one of them can be true. Since we've found one true statement (it doesn't matter whether it's B or D), we can deduce that C did it. (A more efficient, but often overlooked strategy).

  • Background Information

    Learning theories allow teachers to better understand the process of learning.

    Together with the use of technology, learn theories have made a significant impact in the classroom.

    There are many learning paradigms, however, behaviorism, cognitivism and constructivism will be the focus for this lesson.

  • BehaviorismThe theory originates from the works of Ivan Pavlovs, classical conditioning, and B. F. Skinners, operant conditioning.

    Classical Conditioning is when an unconditioned stimulus and response is manipulated with a conditioned stimulus to create a conditioned response.

    Operant Conditioning is a controlled response with a reward/ punishment system according to the behavior.

    The learner needs reinforcements to keep interest.

    Stimuli are effective in controlling behavior.

    As a result, the behaviors can be measured to record learning success.

  • CognitivismInformation Processing looks at how information is retrieved and stored.This theory focuses on how to store and retrieve information. Learning is attained through rehearsal and consistent use of the information. Retention strategies such as breaking down information and comparing the information to long term storage are great techniques.

  • ConstructivismConstructivism views learning as a process in which the learner constructs knowledge based on their past experiences.

    The teacher only acts as a facilitator who encourages students to explore within a given framework.

    Learners may collaborate with others to organize their ideas and learn from each other to construct their own knowledge.

  • EFFECTIVE TEACHER

  • IntroductionHow to become an effective teacher?There are 4 factors that effective teacher must do, which are:1. engage in quality planning and preparation2. Prepare a positive classroom environment3. Use proven instructional technique4. Exhibit professional behaviour

  • ObjectivesAfter completing this chapter you should be able to :1. Define teaching and explain the concept of teaching as an art and as a science2. Describe the characteristic and skills associated with effective teaching and reflective teaching as well as the constructivist approach to learning

  • 3. Differentiate among the five categories of time found in schools4. Describe the expectation and standards associated with teaching and learning5. Explain why teachers need an understanding of students6. Discuss the importance of and technique for teaching students how to learn

  • DefinitionMoore (2001), teaching as the actions of someone who is trying to assist others to reach their fullest potential in all aspects of development.

  • Is teaching an art or science?Some expert says that: teachers are born not made and the ability to be an effective teacher cannot be taught and good teaching is primarily creative art.Others argue that teaching is a science with specific laws and principles that can be taught.What do you think? Is teaching an art or science? Give an argumentation to this statement.

  • Natural teaching instinctLearned teaching principlesThe most important thing is teaching needs skills, so what do you think about it? ArtScience

  • Exactly what is effective teaching?Effectiveness depends on the subject, students, and environmental conditions.According to National Commission on Teaching & Americas Future, 1996: teacher knowledge and what teacher do are the most important influences on what students learn.Based on research, the important elements of effective teaching are: teacher knowledge of subject matter, student learning, and teaching methods.

  • Others opinion about effective teaching that teacher must be prepared to be self-monitoring individuals. (dia dapat memonitor dirinya)Self monitoring requires that teacher have skills that enable self-analysis of teaching episodes, they reflect and focus on events rather than on personalities and on systematic observation for patterns and trends in teaching and learning behavior.The contradiction

  • This contrasting ideas suggest that to be effective teacher must inquire into students experiences and build an understanding of learners and capacity to analyze what occurs in classroom and in the lives of their students.The effect is: teacher must change their orientation from a view of teaching as static with simple formulas, to teaching as dynamic and ever changing. A reflective teacher

  • Reflective teacherLearn everything about teaching from both theory and practice.They teach and reflect on the teaching Think deeply about the theory and practiceSo, they become sensitive to diversity of students needs and family background.They always ask how to make learning process succeed, how to improve students achievement? What can I do to make my students motivated?

  • SummaryEffective teachers know that good teaching is more than simply explaining, lecturing and discussing. To be effective teachers must be well organized.

  • Organized TeachersOrganized means that teacher prepare everything that they need in teaching. They must have plan what to do, knowledge about the subject matter and skills how to teach.

  • Danielson (1996), found that effective teachers need: A knowledge of content and pedagogy (know their subject and how to teach it)A knowledge of students (know how students learn and develop)The ability to select instructional goals (set appropriate expectations)A knowledge of resources (can locate the material and people that will enhance instruction)The ability to design instruction (can plan effective lesson plans), andThe ability to design students evaluation (can design fair and meaningful evaluation)

  • Karakteristik Ilmu KimiaMenurut Middlecamp & Kean (1985):Sebagian besar memuat materi yang abstrakObjek yang dipelejari merupakan penyederhanaan dari yang sebenarnyaMateri berurutan dan berkembang serta berjenjangTidak hanya berisi soal-soal hitungan

  • Menurut Mary B.Nakhleh (Asal dari Purdue Uni,USA) (1991), Robert Bob Bucat (UWA ,Autralia) (1992), kimia memiliki dua aspek pemahaman, yaitu:Konseptual, konsep-konsep, seperti: partikel, hukum dasar kimiaAlgoritmik, hitungan, memuat rumus-rumus matematika, seperti stoikiometri

  • Menurut Johnston (1991) dalam Gabel (1999), kimia dapat direpresentasikan melalui 3 level multipel representasi, yaitu:Makroskopik, sesuatu yang dapat dilihat oleh mata telanjangSimbolik, simbol-simbolMikroskopik, level partikulat, tidak dapat dilihat dengan mata telanjang.

  • KesimpulanBerdasarkan uraian di atas, untuk mengajarkan Ilmu kimia membutuhkan strategi, pendekatan, metode, dan teknik tertentu, yang disesuaikan dengan materi dan karakteristik siswa.

  • DefinitionPendekatan pembelajarandapat diartikan sebagai titik tolak atau sudut pandang kita terhadap proses pembelajaran, yang merujuk pada pandangan tentang terjadinya suatu proses yang sifatnya masih sangat umum, di dalamnya mewadahi, menginsiprasi, menguatkan, dan melatari metode pembelajaran dengan cakupan teoretis tertentu

  • Dilihat dari pendekatannya, pembelajaran terdapat dua jenis pendekatan, yaitu: (1) pendekatan pembelajaran yang berorientasi atau berpusat pada siswa (student centered approach) dan (2) pendekatan pembelajaran yang berorientasi atau berpusat pada guru (teacher centered approach).

  • Strategi pembelajaran.Daripendekatan pembelajaranyang telah ditetapkan selanjutnya diturunkan ke dalamStrategi Pembelajaran. Newman dan Logan (Abin Syamsuddin Makmun, 2003) mengemukakan empat unsur strategi dari setiap usaha, yaitu:Mengidentifikasi dan menetapkan spesifikasi dan kualifikasi hasil (out put) dan sasaran (target) yang harus dicapai, dengan mempertimbangkan aspirasi dan selera masyarakat yang memerlukannya.Mempertimbangkan dan memilih jalan pendekatan utama (basic way) yang paling efektif untuk mencapai sasaran.Mempertimbangkan dan menetapkan langkah-langkah (steps) yang akan dtempuh sejak titik awal sampai dengan sasaran.

  • Mempertimbangkan dan menetapkan tolok ukur (criteria) dan patokan ukuran (standard) untuk mengukur dan menilai taraf keberhasilan (achievement) usaha.Jika kita terapkan dalam konteks pembelajaran, keempat unsur tersebut adalah:Menetapkan spesifikasi dan kualifikasi tujuan pembelajaran yakni perubahan profil perilaku dan pribadi peserta didik.Mempertimbangkan dan memilih sistem pendekatan pembelajaran yang dipandang paling efektif.Mempertimbangkan dan menetapkan langkah-langkah atau prosedur, metode dan teknik pembelajaran.Menetapkan norma-norma dan batas minimum ukuran keberhasilan atau kriteria dan ukuran baku keberhasilan.
