My Self-Assigned Task
To offer you
a ‘sampler plate’
of bite-size ideas
that you might use to
create your own
MEMORABLE CLASSROOM EXPERIENCES
3
Be BRAVE!
Act on good ideas.
Developing ‘formal’ activities is a process
(and not always necessary).
4
Have FUN!
If you like something –
find a way to use it.
Enthusiasm is Contagious!
Wooden Farm Animal Puzzles

Wooden Puzzle Activity 1
Experimental Design Issues
The Question: I want to know if some of these puzzles are easier to put together than others. What should I do?
(Follow their lead; prompt only if necessary.)
What should be measured?
How should the data be collected?
What should be randomized?6
Wooden Puzzle Activity 2
Comparing Multiple MeansData collected during one class period I timed all subjectsData set posted for students to analyzeResults discussed the following class

Does Learning Take Place?Data collected during one class periodStudents worked in pairs
Students were randomized to the puzzle stations and to the individual puzzles
Those not at the puzzle stations were completing a group assignment

Sampling Distribution Stations (known and unknown distributions)
1. Tacks (point up)2. Casino Dice (3’s and 4’s)3. BB Bowl (greens)4. Regular Dice (odds) (10 and 20)5. Chips (above 1.5)6. Mini Dice (6’s) 7. Sea Shells (avg wt 4 and 9)8. Bead Bowl (non-white)9. In and Out Dice (both odd)10. Stones (avg wt 9) 23
Sampling Distribution Day
Students work in pairs 4 minutes per station 6-8 rotations
At the end of data collection students take data sheets and compute means and standard deviations of sample means or sample proportions

Sampling Distribution Day
END OF HOUR DISCUSSION INCLUDES: Comparing average values of observed
proportions to theoretical value of the known distributions
Comparing standard deviations of observed proportions from the same experiment but with different sample sizes
Average value for percentage of tacks landing point up is discussed
