<![CDATA[Background. Basketball shooting is a fundamental skill in physical education, and cooperative learning may provide structured opportunities for repeated practice and peer interaction. Objective. This study examined whether a class receiving the Teams Games Tournament (TGT) learning model showed greater improvement in basketball shooting skills than a comparison class among junior high school students. Methods. A quantitative quasi-experimental nonequivalent control group design involved 88 students from two intact classes at SMP Negeri 33 Kota Bekasi, with 44 students in the TGT class and 44 in the control class. Basketball shooting performance was assessed using a four-component rubric covering initial stance, movement execution, movement coordination, and shooting accuracy. Both classes completed a pretest and posttest with six teaching sessions between assessments. Descriptive statistics, assumption tests, paired-samples t-tests, and an exploratory Mann–Whitney U comparison of individual gain scores were conducted. Results. The TGT class increased from 58.38 to 74.29 (mean gain 15.91), whereas the control class increased from 59.80 to 68.04 (mean gain 8.24). The exploratory gain comparison yielded U = 652.500, Z = -2.658, and p = .008. Conclusion. Within the two participating classes, the TGT class showed a larger observed improvement; however, because only one intact class represented each condition, the result cannot separate instructional condition from class-level characteristics and should not be interpreted as a fully controlled causal effect.]]>
