Effect of myplate: the new food guide musical as a teaching method for elementary school students to increase nutrition knowledge of the five food groups
The purpose of the study was to determine if MyPlate: The New Food Guide Musical was an effective method to positively impact elementary schoolchildren's knowledge about MyPlate, nutrition, and physical activity knowledge using data from1,045 students in four schools in Los Angeles Unified School District completed the pretest and posttest survey. Data were collected from actors (i.e., those students who rehearsed and performed the musical) and viewers (i.e., those students who viewed the performance). Paired samples t-tests demonstrated that students had a statistically significant increase in scores from pretest to posttest on MyPlate, nutrition, and physical activity knowledge in each school and between all four schools. Actors were compared to viewers using independent samples t-tests. Actors had statistically significant greater increases in scores from pretest to posttest on (1) MyPlate knowledge in two schools, and (2) physical activity knowledge in one school. School personnel from one school gave observations of children's behavior changers and overall feedback, suggesting the musical had a positive impact.
