Pengembangan Soal Berbasis Kemampuan Berpikir Kritis Matematis Materi SPLTV Bernuansa Islami Kelas X

This study aims to produce a product, namely Questions Based on Students’ Mathematical Critical Thinking Ability on the Material of the Three Variable Linear Equation System (SPLTV) with Islamic Nuances for Class X which has been tested for validity. The development of questions in this study uses the type of Research and Development (R&D) with the Plomp Model, with stages: 1) Initial Investigation Phase, 2) Design Phase, 3) Realization/Construction Phase, 4) Test Phase, Evaluation, Revision and 5) Implementation Phase. The research data collection instrument is a product validation sheet of questions. The data collection technique used is validation data from 2 lecturers of Mathematics Eduction FKIP UIR and 2 mathematics techers each from MAN 01 Indragiri Hilir and SMA 1 Negeri Tembilahan. The data analysis technique used is validation data analysis. This product is only limited to measuring validity and has not yet reached the trial or deployment stage due to the covid-19 pandemic, so researchers cannot carry out the product trial process. From the results of the research, it was obtained thet the product validation results were 0.88 with a very valid category. From the results of the study, a product was obtained, namely a Question Based on Students’ Mathematical Critical Thinking Ability in the Material of a Three Variable Linear Equation System (SPLTV) with Islamic Nuances for Class X which was tested for validity.
