The post During the first half of the spring semester, 120 male students and 120 female students in grade 10 at a public high school in a large metropolitan area in the southwestern region of the United States were randomly assigned to one of three study environment: study in front of the TV, at the library, or in the food court. The students could ONLY study in the environment to which they were assigned during the research period. At the end of the 7-week research period, mid-term GPA was computed for each student. A change score was computed for each student: each student’s spring midterm GPA was subtracted from his or her GPA for the preceding fall semester. The difference was each student’s GPA Improvement score. The GPA improvement score was used to measure academic performance. appeared first on Psychology Homework.
