Question 13

Suppose I want to know whether or not using PowerPointsin class will help to improve student understanding.What would be the best way for me to investigate this research question?

You should address the following points with your answer:

1. What study design would best help me here?

2. Hypothetically speaking, how could I go about conducting this study?

3. Are there any special considerations I should make using this study? (e.g., if I am to conduct an experiment, how should I go about deciding who gets what teaching style?)

Question 14

Suppose I have taken your advice and decided to conduct the research study you have suggested in the previous question.

1. What are some likely variables I should collect with this study to answer my research question?(Hint:I would think with a study like this I would need toatleastinclude: class size,studentpre-test scores,studentpost-test scores,student demographics like age/race/gender.)

2. What would be the best way to summarize the distributions of the variables I have collected in this study?(I.E.For any necessary variables,give the best descriptive statistics I could provide.Remember to discuss graphs/figures as well as numerical summaries where possible.)
