Twenty Years of Intervention Research in School Physical Education in the JTPE and RQES

Abstract

ABSTRACT Background/Purpose: The purpose of the present study was to review intervention studies in school physical education, with a goal of identifying the gaps and future trends of intervention research in the field of physical education. Methods: A total of 71 quantitative experimental studies were identified by manually examining all the articles published in the Journal of Teaching in Physical Education and Research Quarterly for Exercise and Sport from January 1998 to December 2018. All the studies were coded using a coding template. The interrater reliability among three coders exceeded 85%. The frequencies and percentages for each category were calculated as appropriate. Results: Eighty-five percent of experimental studies were guided by a theoretical framework. Interventions used various types of research designs. A variety of dependent variables were measured with the majority of studies focusing on student motivation and psychomotor skills. The intervention length ranged from 5 min to 2 years. Fifty-six percent of studies reported effect sizes. The reported types and strength of effect size varied. Forty-nine percent of them reported an intervention fidelity check. Conclusion: A limited number of experimental studies had been conducted from 1998 to 2018. The rigor of these experimental studies needs significant improvement. More experimental studies with a randomized controlled trial design are needed.
