PENGEMBANGAN MEDIA PEMBELAJARAN FLASH CARD UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS SISWA SMA PADA MATERI DIMENSI TIGA

The purpose of this research is to develop a valid, practical, and effective Flash Card learning media for use in learning mathematics, especially in Three Dimensional material. This type of research is Research and Development (RnD) with the ADDIE model. ADDIE consists of analys, design, development, implementation, and evaluation. The developed media passed three tests, namely validity, practicality, and effectiveness tests. The instruments used in this study were validation questionnaires, student response questionnaires, and tests. The research was conducted at MA Al-Azhar Jombang which involved two classes with a total of 52 students. The results showed that the Flash Card learning media met the validity test with a score of 94% (very feasible) by mathematics lecturers and 87% (very feasible) by mathematics teachers. In addition, Flash Card learning media also improves student learning outcomes as evidenced by a sig. (2-tailed) value of 0.000 which indicates that there is a difference or influence in the use of media because the magnitude of the test results is < the set significance value level of 0.05. The use of Flash Card learning media also received a positive response from students as indicated by the large average number of assessments for each student response questionnaire point of 85.53%.
