The Development of an Activity Model Integrating Physical Exercise and Social Media Literacy for Grade 9 Students at Ban Nong Yai Municipal School

Abstract

This study aims to examine appropriate physical exercise activities and online social literacy and to develop an activity model for Grade 9 students at Ban Nong Yai Municipal School. A research and development (R&D) approach was employed, consisting of three phases: 1) assessment of physical fitness and online behavior, 2) implementation of intervention activities, and 3) evaluation. The sample comprised 43 Grade 9 students, selected through purposive sampling. The findings revealed that Phase 1, students exhibited moderate to low levels of physical fitness, particularly in sit-and-reach and high-knee lifting tests. Regarding online behavior, most students used smartphones primarily for entertainment between 20:01–24:00 hours, with a frequency of 6–10 times per day. In Phase 2, the “3F Model” was developed, consisting of: 1) Fun & Enjoy, emphasizing enjoyment; 2) Simple & Easy, focusing on simplicity and no requirement for equipment; and 3) Firm & Healthy, promoting physical health. Following participation, students’ physical fitness improved significantly, especially in the 60-second sit-up test, with 95.65% of male students and 85% of female students achieving excellent levels. In Phase 3, overall satisfaction was reported at a high level (mean = 4.06). The model effectively enhanced students’ physical health and fostered positive attitudes toward exercise.
