Tujuan Penelitian ini adalah untuk mengembangkan sebuah model Didactic Design Research untuk mengatasi hambatan belajar matematika mahasiswa. Jenis penelitian ini adalah penelitian dan pengembangan dengan model ADDIE. Mengenai validitas produk, hasil data validasi dari ahli materi diperoleh persentase 82,15% yang termasuk dalam kategori layak dan revisi serta hasil data validasi ahli model diperoleh persentase 83,42% dengan kategori layak. Rancangan didaktis yang dikembangkan untuk mengatasi hambatan belajar matematika mahasiswa didasarkan pada hubungan dosen, mahasiswa, dan materi digambarkan menjadi sebuah Segitiga Didaktis. Segitiga Didaktis ini kemudian dimodifikasi karena hanya menggambarkan hubungan pedagogis (HP) antar dosen dan mahasiswa dan hubungan didaktis (HD) antara mahasiswa dan materi. Setelah dimodifikasi Segitiga Didaktis menggambarkan hubungan pedagogis (HP) antar dosen dan mahasiswa dan hubungan didaktis (HD) antara mahasiswa dan materi, dan hubungan antisipasi dosen dan materi yang disebut sebagai antisipasi didaktis dan pedagogis (ADP).

This study aims to determine whether there is an influence of the problem-based learning model (PBL) with a STEM approach on the mathematical problem solving ability of grade VIII students of SMP Negeri 17 Medan. This research was conducted at SMP N 17 Medan T.A 2023/2024. The research method used is a quasi-experimental method. The sample of this study consisted of two classes, namely class VIII-3 as an experimental class taught with a PBL model with a STEM approach and class VIII-4 as a control class taught with conventional models. Based on descriptive statistics and categorization of research results, it was found that the mathematical problem solving ability of experimental class students was 67,74% of students in the high category, 32.26% of other students in the medium category, and no students in the low category. Meanwhile, in the control class, 15,63% of students were in the high level of problem solving ability, 53,13% were in the medium level and 31,24% of students were in the category low category. Thus it can be seen that the mathematical problem solving ability of grade students taught with PBL with a STEM approach is better than conventional learning models. Furthermore, with inferential statistical analysis for the t test, calculated t value = 2,42 and ttable = 1,999623, thus t calculated > t table means that the problem-solving ability of students taught with PBL with a STEM approach is not the same as students who use the learning conventional model. With further analysis, Fcalculated = 5,6847 and F table = 3,998494482, then calculated F > F table so it can be concluded that problem-based learning models with a STEM approach have a significant effect on students' mathematical problem solving abilities.

Based on the results of initial observations at SMP Negeri 40 Medan, there are teachers who have not maximized the design, development, and utilization of learning media, especially flipbook media that has never been implemented. As well as the mathematical literacy skills and learning motivation of students are still low. This study aims to (1) produce flipbook media based on the Problem Based Learning learning model that is valid, practical and effective, (2) analyze the improvement of mathematical literacy skills and (3) analyze the improvement of student learning motivation using flipbook media based on Problem Based Learning. This study uses the ADDIE model. This study involved class VIII students of SMP Negeri 40 Medan. The instruments used in the development of flipbook media are Teaching Modules, LKPD, Mathematical Literacy Ability Tests and Student Learning Motivation Questionnaires. The results of the study are that the flipbook media meets the valid criteria with a score of 4.69, then the flipbook media was tested to obtain practical and effective media so that it meets the practical criteria with a score of 88.95, and the flipbook media meets the effective criteria with a score of 87.79. The increase in mathematical literacy skills measured by N-gain on the development trial conducted twice against pretest with posttest I with an average N-gain of 0.33 in the medium category, then against posttest I and posttest II with an average N-gain of 0.73 in the high category. Furthermore, the increase in students' learning motivation by measuring the pretest and posttest with an average N-gain of 0.6 in the medium category. Based on the N-gain results, it is stated that flipbook media based on the Problem Based Learning learning model is able to improve students' mathematical literacy skills and learning motivation at SMP Negeri 40 Medan.
