8. Mr. Jacobs wants to find out whether a new program for teaching physical education promotes students’ physical development. He gives his students a number of tests before they begin the program (pretests) and the same tests again after they have been in the program for eight months (post tests). He finds that the students’ post test scores are higher than their pretest scores and so concludes that the program is effective. What is definitely wrong with Mr. Jacobs’ conclusion?
a. Tests are not a good measure of physical development. b. There are other possible explanations for his results. c. Eight months is too short a time for such a program to have a long-term effect. d. The post tests should always be different from the pretests.
9. Most developmental theorists agree that:

10. Which one of the following statements reflects what developmentalists mean by the term maturation?
a. developmental changes that are controlled largely by heredity b. changes that reflect increasingly appropriate social behavior c. changes related specifically to children’s emotional development d. changes related specifically to children’s physical development
