The aim of this research is to determine the development of e-comic learning media to improve the mathematics problem solving abilities of 4th grade elementary school students. The type of research carried out uses descriptive qualitative with field research methods. The type of research used is Research and Development with a 4-D design which includes a modification of the Thiagarajan model (1974:36). The stages carried out in 4-D design are the definition stage, design stage, development stage by carrying out validation tests on material, media and learning experts. After the results of the e-comics media development material test, media expert test and learning expert test were categorized as valid and feasible. Then the final stage is carried out, namely the distribution stage which aims to promote e-comic media to teachers and students. So it can be concluded that the development of e-comics media is suitable for application in mathematics learning to improve students' mathematical problem solving abilities.

Penelitian ini bertujuan untuk mengeksplorasi model mental, strategi, dan skema berpikir mahasiswa dalam memecahkan masalah luas segitiga serta menelaah efektivitas desain didaktis berbasis pendekatan metakognitif dalam meningkatkan kemampuan pemecahan masalah geometri. Penelitian menggunakan metode studi kasus eksploratif dengan pendekatan kualitatif deskriptif yang melibatkan 23 mahasiswa Program Studi Pendidikan Matematika Universitas Negeri Medan tahun akademik 2024/2025 sebagai subjek penelitian. Data dikumpulkan melalui lembar tugas pemecahan masalah bidang datar dan dianalisis melalui tiga tahap, yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa representasi visual mahasiswa masih dipengaruhi oleh citra mental prototipe, sehingga strategi pembagian bangun datar belum bervariasi. Namun, penerapan desain didaktis berbasis pendekatan metakognitif terbukti efektif dalam meningkatkan kesadaran mahasiswa terhadap proses berpikir visual mereka. Pendekatan ini tidak hanya memperkaya citra mental dan kesadaran visual mahasiswa, tetapi juga memperbaiki ketepatan strategi dan fleksibilitas representasi geometri dalam memecahkan masalah luas segitiga. Dengan demikian, integrasi metakognisi dalam pembelajaran geometri berpotensi meningkatkan kualitas model mental dan kemampuan berpikir spasial calon guru matematika.

STAD type cooperative model. The subjects in this research were 30 class VII students of SMP Negeri 4 Pantai Labu and the object of this research was to see the learning outcomes of the learning process carried out. 2) the effectiveness of Learning Design Development using the STAD Type Cooperative model developed on students' mathematical abilities. The learning design developed (STAD Type Cooperative Model, has met the level of validity with a reliability coefficient of 0.790. Based on data obtained from testing the learning design, it is known that: 1) the design developed has been able to meet the effectiveness of the learning process, 2) Obtained learning outcomes good for students' mathematical abilities. Based on the research results, it can be concluded that all aspects determined to declare a design development product valid and effective have been fulfilled, so the development cycle to obtain a valid and effective learning design has ended. Improved student learning outcomes can be seen from the results of students' mathematical ability tests on flat plane material. In the trial, there were 26 students (86.67%) out of 30 students who took the posttest with a level of student mathematical ability in the minimum category B. This shows that the percentage of students who have completed their mathematical abilities on flat plane material has increased from trial I to trial II, namely 16.67%.

The purpose of this study was to determine: 1) increasing mathematical connection abilities through a contextual approach. Educational science is a continuation of education. Education and Culture continues to carry out reforms and innovations in the field of education, one of which is curriculum renewal and innovation, namely the birth of the 2013 curriculum which is a shift in the development paradigm from the 20th century to the 21st century. Mathematics is one of the mandatory subjects in the 2013 curriculum which plays a very important role in improving human resources. Mathematical connection abilities are closely related to problem solving abilities which of course will help students to improve their mathematical connections, and vice versa. Therefore, it is very important that mathematical connection abilities to be able to improve students' mathematical connection abilities through contextual learning are a very appropriate choice. Johnson (2010:35) states that contextual learning and teaching involves students in important activities that help them relate academic lessons to the real-life contexts they face. Based on the results of research by experts, the average normalized gain score for mathematical connection abilities of students who were given contextual learning was higher than students who were given regular learning. The results of this study show that the average increase in the mathematical connection abilities of students who were given contextual learning was higher than that of students who were given regular learning.
