To help assess student learning in her development physics c

To help assess student learning in her development physics courses, a physics professor at a university implemented pre-and post-test for her developmental physics students. A knowledge-gained score was obtained by taking the difference of the two test scores. What type of experimental design is this? Survey, matched pair, completely randomized assignment, or randomized block design. What is the response variable in this experiment? Total in test scores, the score on the pretest, difference in test scores, or the score on the posttest. What is the treatment? physics scores, background of student, physics course, or type of school.

Solution

a)

randomized block design

since , the score of students is randomized individually in both pre-test and post test

b)

the response variable is difference in test scores

c)

Physics scores
