Abstract:
Background and Study Aim. Breaststroke swimming is one of the compulsory subjects for students majoring in sports education at Lambung Mangkurat University. Thus, it is important to have good breaststroke swimming skills so that later it will become the basis for creating experienced and potential teachers. Therefore, there is a need for special treatment to improve breaststroke swimming skills. This study aims to provide evidence of the integration of project based learning models with interactive multimedia on improving students' breaststroke swimming skills. Material and Methods. This research is a quasi-experimental type with a pretest posttest non-equivalent control group design. The sampling technique used purposive sampling so that as many as 90 sports education students were sampled, namely 45 experimental groups and 45 control groups. The instrument resulting from breaststroke swimming skills was designed by the researcher, based on the theory of swimming experts, all descriptors for the breaststroke swimming instrument totalled 35 items. Furthermore, the analysis of the data in this study through the stages of normality test, homogeneity test, and hypothesis testing. Results. The hypothesis test on the experimental group indicator with the PBL-Multimedia Interactive treatment showed a significance value of 0.000 <0.05 which means it is significant. Furthermore, the results on the control group indicator showed a significance value of 0.000 <0.05, so there was a significant increase. The results also show a difference with a significance of 0.001 <0.05, which means that the PBL- Multimedia Interactive experimental group and the control group (Conventional) have a significant difference in the effect on the posttest score. Conclusions. This study shows that the PBL-Multimedia Interactive model integration treatment has a significant effect on improving students' breaststroke swimming skills. Where the integration of the PBL-Multimedia Interactive model is proven to be more effective than the conventional model. That way, the integration of the PBL-Multimedia Interactive model is effective and can be applied in swimming learning, especially in improving breaststroke swimming
