Abstract

This Classroom Action Research (CAR) investigated the effectiveness of the Student Teams Achievement Division (STAD) cooperative learning model in enhancing volleyball underhand passing skills among tenth-grade students at High Secondary School YP PGRI 1 Makassar, Indonesia. Addressing baseline performance gaps—where only 29.2% of students achieved the Minimum Mastery Criteria (KKM = 80), heavily hindered by low psychomotor scores (mean = 57.90)—the study employed a two-cycle spiral design (planning, action, observation, reflection) involving 24 students selected via total sampling during the 2025/2026 academic year. Data was gathered through observation instruments, cognitive assessments, and psychomotor evaluation rubrics across the cognitive, affective, and psychomotor domains. Following Cycle I interventions, classical mastery increased to 54.2% (mean = 81.02). Subsequent pedagogical refinements in Cycle II yielded a 100% classical mastery rate (mean = 92.39), with substantial gains across cognitive (95.67), affective (97.14), and psychomotor (84.38) domains. The results demonstrate that STAD’s structured peer-tutoring and group-reward framework successfully remediates persistent motor execution errors while fostering affective engagement and conceptual understanding. These findings offer secondary physical education practitioners an evidence-based, replicable instructional strategy to bridge holistic learning domains in team-sport skill acquisition.

Abstract

Low psychomotor skill levels in badminton backhand serves remain a persistent challenge in high school physical education due to monotonous, teacher-centered instructional approaches. This Classroom Action Research (CAR) investigated the effectiveness of the Service Duel Approach—a paired, game-based competitive framework—in improving backhand serve accuracy, technical understanding, and learning engagement among 24 ninth-grade students at High Secondary School YP PGRI 1 Makassar (selected via purposeful sampling). Guided by the Kemmis and McTaggart action research cycle, data were collected over two cycles using a validated zone-based psychomotor service test (content validity index CVI = 0.88, inter-rater reliability ICC = 0.91), a cognitive understanding test (KR-20 = 0.84), and a structured affective observation sheet. Baseline observations indicated severe deficit, with only 12.50% of participants achieving the Minimum Mastery Criteria (KKTP ≥ 80; M = 68.00). Following Cycle I interventions, mastery reached 41.67% (M = 74.50). With refined targeted corrective feedback, basic mechanical drills, and peer assessment in Cycle II, 100.00% of participants met the mastery threshold (M = 83.42). While the 100% completion rate reflects specific classroom success within the CAR framework, potential novelty effects and short evaluation windows represent acknowledged study boundaries. The findings demonstrate that structured gamified duels successfully optimize psychomotor coordination and motor learning.
