Abstract

Introduction: Teacher self-efficacy is crucial for improving Physical Education, yet supervision is often administrative rather than developmental.

Objective: This study developed and validated the SPS (Support–Participant–Skill) collaborative supervision model as a continuing professional development framework for strengthening teacher self-efficacy in Physical Education.

Methodology: A Research and Development design with an embedded one-group pretest–posttest evaluation involved 70 teachers from 20 vocational schools in 10 cities across 5 Indonesian provinces. Data were collected using expert validation sheets, feasibility and perceived effectiveness questionnaires, teacher self-efficacy scales, observation sheets, and reflection forms.

Results: SPS showed high validity (96.9%), feasibility (89.4%), perceived effectiveness (89.4%), and a significant increase in teacher self-efficacy from 3.39 to 4.08 (p < .001).

Discussion: SPS repositioned supervision as supportive, participatory, and skill-oriented professional learning.

Conclusion: SPS provides a practical school-based CPD model for strengthening Physical Education teacher self-efficacy.
