Abstract

This study aims to analyze the effectiveness of the explicit-reflective approach to enhance the understanding of NOS and concept mastery, and to see the relationship between the two variables through the application of an explicit-reflective approach in middle school students in Sengkang, South Sulawesi. A total of 21 students of grade 8 in public middle school became the sample in this study. To achieve the objectives, the research method employed was pre-experimental through The One-Group Pretest-Posttest Design. The result showed that the understanding of NOS and students^ concept mastery increased significantly after the implementation of explicit-reflective approach. Paired-t-samples test results indicated that the average posttest score of NOS understanding and mastery of students^ concepts increased significantly compared to the pretest score (sig. 0.00<0.05). The correlation between the enhancement of students^ NOS understanding and students^ concept mastery was obtained through the Pearson product-moment correlation analyst. The relationship between two variables was significant with the moderate category (r = 0.491).
