Small-Group Discussions about Your Experiment

Explain your proposed study to your group members. As you explain, make sure you explain the following details:

1. What behavior you intend to modify
2. Your system of rewards and punishments
3. Your hypothesis

Also show your group members the form that you will use to collect your data.
After each person has presented his or her experiment and data form, the other group members should discuss the experiment, including the following questions. The author should take notes during this discussion.

1. Do you think the experiment seems reasonable? Do you think the author can actually perform this in a week?

2. Is the hypothesis interesting? Does it merely restate the prompt, or does it offer an original claim about what the experiment will prove?

3. Does the behavior the author is attempting to modify recur daily? Will the experiment generate enough data to make a reasonable conclusion about the hypothesis?

4. Are the rewards and punishments in order? Are the punishments merely a lack of reward, or vice versa? Do you think the rewards and punishments adequately reinforce the desired behavior?

5. Examine the data form. Will the form collect the data necessary to prove the hypothesis? Explain how the evidence gathered on the data form will prove the claim made in the hypothesis.

6. Do you recognize any confounding variables? Check this site for information about confounding variables: http://score.kings.k12.ca.us/lessons/wwwstats/confounding.variables.html

7. Do you notice anything else that may affect the experiment’s success?
