The development of learning instrument with Contextual Teaching And Learning (CTL) based on Lesson Study for Learning Community (LSLC) on two variable linear equations and its effect on creative thinking of junior high school student

Abstract

This study aims to develop learning instrument with contextual teaching and learning (CTL) based on lesson study for learning community (LSLC) on the two-variable linear equation material for grade VIII students of Junior High School/MTs and its effect on students’ creative thinking. The method used is mix methods with a combination model of sequential exploratory design with the Thiagarajan development model through four stages, those are define, design, develop, and disseminate. In experimental research using a quasi experimental design, namely pretest posttest non equivalent control group design. The subjects of this study were students of MTs Bustanul Ulum Panti, class VIIIA as the experimental class and class VIIIB as the control class. Students’ creative thinking abilities were measured using tests of creative thinking abilities. The assumption test for normality and homogeneity of variance is carried out before the data is analyzed. This research generates learning instrument that meet the criteria of practical validity, and effective, also the significance value (t-tailed) of 0,000 (p < 0,05) which indicates the application of learning has a significant effect on students’ creative thinking abilities.
