WWC Review of the Report "Evaluation of a Two-Year Middle-School Physical Education Intervention: M-SPAN"
What Works Clearinghouse
The study reviewed in this paper examined the effect of the "Middle School Physical Activity and Nutrition" ("M-SPAN)" intervention on the physical activity level of middle school students. For this 2-year study, 24 middle schools from six districts in southern California were stratified by school district and then randomly assigned to either "M-SPAN" or a comparison condition. To assess students' physical activity levels and the content (referred to as "lesson context" in the article) of physical education (PE) classes, researchers observed students in PE classes on 11 randomly selected days for each school throughout the 2-year study period. Researchers documented the lesson content of the classes and observed a total of 1,849 lessons taught by 214 teachers (between seven and 14 teachers per school, with an average class size of 37.5 students). The study assessed the effectiveness of "M-SPAN" by examining moderate-to-vigorous physical activity (MVPA), the amount of time students spent either walking or being very active, and other types of activities and PE lesson content across schools that received the "M-SPAN" training. The study found that the "M-SPAN" intervention caused a statistically significant improvement in the amount of time students spent in MVPA, and the What Works Clearinghouse (WWC) confirms this study-level finding. The WWC calculated the "M-SPAN" intervention as improving the MVPA in schools by an average of 3 minutes per lesson (approximately 0.79 school standard deviation units) across the 2-year period of the study. The research described in this report meets WWC evidence standards without reservations. Appended are: (1) Study details; (2) Outcome measures for each domain; (3) Study findings for each domain; and (4) Supplemental findings by domain. A glossary of terms is included. (Contains 3 endnotes.)
