Procedures
1. Find a classmate to work with. Time
each other as you solve a puzzle or maze. Take turns until you have
each completed the puzzle or maze five times. (Don't watch each other's
solutions!) Time other people solving your puzzle or maze five times.
Organize all the trials and times in a table. Summarize your results.
What effect does repetition have on solving time? How would more
repetitions affect the time?

Repetition
make the times better. The times should get better
with more
repetitions.
2. Find a group of at least 3 students to work
with. Make a list of a dozen words. Give each member ten
seconds to study the list. Then have them write down items they can
recall. Record the number of correct items. Give each member an
additional ten seconds to study the list again. Have them write down
items and record the results. Repeat this two more times and describe
any correlation you see in the data from the first experiment.

The times got better just like with the puzzle
3. Create scatter plots of the data you collected
for the two activities. Describe any correlations suggested by the scatter
plots. Does a line seem to fit your data? What would happen to
a line of best fit after several more trials?
Any plot that shows a positive correlation is
good here. A line would fit and the trials would come closer and close
to the line
4. Present your project
in a visual display. For each experiment you have conducted, you should
show a table of data, a scatter plot of the data including a line of
best fit, and a paragraph analyzing what happened. Your presentation
should discuss any correlations and lines of best fit you have found and any
conclusions you have drawn.
5. Evaluate the current homework load in your
math class. Do you think you get enough practice problems? Should
there be an increase or decrease in the number of practice problems you do?
Why? How will these changes effect test scores?
