Abstract

The aim of this research was to develop instructional materials in the form of student worksheets based on realistic mathematics education to facilitate valid, practical, and effective critical thinking skills in trigonometry. This research was a development research (R&D) using the ADDIE model (Analysis, Design, Develop, Implementation, and Evaluation). The research was conducted at SMA N 4 Yogyakarta with the research subjects being media and material experts from mathematics education lecturers and mathematics educators, as well as Grade X students of SMA N 4 Yogyakarta. The sample in this research was the XE 6 class students. The object of this research was the student worksheets based on Realistic Mathematics Education (RME) to facilitate critical thinking skills. The data collection instruments in this study consisted of validation sheets, student response questionnaire sheets, and critical thinking skills test sheets. The data analysis techniques used were qualitative and quantitative analysis. The research results showed that the validity of the Student Worksheets based on RME to facilitate critical thinking skills was obtained based on assessments from material experts with the criteria of 'very good' and from media experts with the criteria of 'good.' The practicality results indicated that the percentage of ideality was included in the 'good' criteria, making the developed LKPD considered practical. The effectiveness results achieved the 'good' criteria, indicating that the LKPD was effective for use. This demonstrated that the Student Worksheet based on RME to facilitate critical thinking skills was valid, practical, and effective for use in mathematics learning.
