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.
