<![CDATA[Study purpose: This study aims to develop a prototype of the "Moving to Learn" Intervention Model that integrates structured physical activity, metacognitive skills training, and resilience building techniques in a practical format for adoption by senior high school teachers. Materials and methods: This study employed a Research and Development (R&D) approach using the 4D procedural model (Define, Design, Develop, Disseminate) by Thiagarajan, Semmel, and Semmel, limited to the Define, Design, and Develop phases. Participants were involved at different stages according to their roles: (1) Needs analysis stage—5 teachers (Physical Education, Guidance and Counseling, and Homeroom Teachers) and 30 grade XI students completed needs assessment questionnaires, with 3 teachers participating in semi-structured interviews; (2) Expert validation stage—3 experts (Physical Education, Educational Psychology, and Learning Technology) validated the prototype; (3) Practicality assessment stage—2 teachers conducted expert reviews and 5 students participated in one-to-one tryout simulations; and (4) Limited trial stage—30 students participated in the pilot implementation without a control group. Quantitative data were analyzed using descriptive statistics (percentages and means), while qualitative data were analyzed using the Miles and Huberman model. Results: Expert validation confirmed the prototype's validity with an average score of 4.2 out of 5, and practicality tests yielded an implementation rate of 85%. In the limited pilot trial without a control group, descriptive improvements were observed across all indicators: physical fitness (VO2Max sufficient category) increased from 35% to 68% (+33%), high metacognitive ability increased from 42% to 73% (+31%), high academic resilience increased from 48% to 79% (+31%), and active interaction in learning increased from 55% to 85% (+30%). These preliminary findings indicate potential promise of the prototype, but they are descriptive in nature and should not be interpreted as statistically significant effects, as no inferential statistical tests were conducted. Conclusion: This developmental study successfully produced a valid and practical prototype of the "Moving to Learn" Model, comprising a teacher's guidebook, student activity modules, and initial assessment instruments. The prototype demonstrates preliminary feasibility for use in senior high school settings, as evidenced by expert validation and practicality assessments. However, because the model was tested only in a limited pilot without a control group, claims of effectiveness cannot be made. The prototype is now ready for further rigorous testing through controlled experimental studies to establish its effectiveness on physical fitness, metacognition, and academic resilience.]]>
