STEM-Based Interactive Learning Media to Improve Student's Critical Thinking Skills on Number System Materials.

Abstract

The goal of the study is to produce STEM-based interactive learning media that can enhance student’s critical thinking skills on number system materials. The research method used is the method of development or Research and Development (R&D) with addie design (Analysis, Design, Development, Implementation, Evaluation). The instruments used in the study consisted of expert media validation sheets, materials, critical thinking tests, and student questionnaire sheets to determine student’s responses to interactive learning media. To find out the practicality and effectiveness of interactive learning media in improving the ability of critical thinking, a double choice test is grounded. The results show that 1) the results of media and material validation by 2 experts were 86% (very high) and the results of validation of tests of learning results by experts and teachers were 90.67% (very high), 2) interactive learning media can improve student’s critical thinking skills which is shown with average pretest results by 54.7%, average post-test by 91.9% and average %N-Gain by 68.48% (height), 3) Student’s responses to the use of interactive learning media earned 84% (excellent) grades.
