The effectiveness of cooperative learning model with inquiry approach for static fluid materials at SMA Negeri 1 Kabila, Indonesia

This research aims to engender effective learning devices using a cooperative learning model with an inquiry approach for static fluid materials. Developing learning devices using a cooperative learning model with an inquiry approach generated products of a lesson plan, learning material, student worksheet, and learning outcome test. The results of validation conducted by two validators exhibited that the learning devices were valid, and each product had a percentage of 85.01-100%. The limited group test, executed to identify 15 students’ responses to the learning devices, resulted in score percentages of 98.33% for the lesson plan, 98.52% for the learning material, 99.33% for the student worksheet, and 99.33% for the learning outcome test. Overall results indicated that the learning devices were very effective for learning. The effectiveness was implied by the mean assessment scores of responses given by eleventh graders from the Science 4 class as participants as follows: 95.83% for the cooperative learning model, 99.72% for the student worksheet, 98.77% for the learning material, and 97.78% for the evaluation tool. A similar analysis performed on eleventh graders from the Science 5 class generated score percentages of 95.83% for the cooperative learning model, 96.67% for the student worksheet, 94.75% for the learning material, and 94.72% for the evaluation tool. In terms of learning outcome tests, eleventh graders from the Science 4 and 5 classess acquired N-Gains of 0.760 and 0.783 (a high category), respectively.
