Abstract

Differentiated learning is an effective strategy for implementing the Kurikulum Merdeka in upper junior high school. This strategy is applied to address several classroom challenges, such as monotonous learning, limited learning resources, a lack of instructional media, and low student motivation. The primary objective of this initiative is to enhance teachers' ability to develop learning modules and assessments tailored to students' characteristics. Through this training, teachers can independently create instructional modules that can be implemented in classroom learning. To achieve this goal, the community service team from the postgraduate school of at Universitas Negeri Medan has designed a series of activities, including preparation, training implementation, mentoring, evaluation, and refinement. The applied method has resulted in learning modules and assessments developed by subject teachers. These modules and assessments are designed based on students' initial abilities and characteristics, leading to improvements in learning outcomes, higher-order thinking skills (HOTS), and student motivation in the learning process. Furthermore, these modules and assessments have become essential instructional tools that teachers utilize in their daily classroom teaching.   Abstrak Pembelajaran berdiferensiasi merupakan salah satu strategi yang tepat dalam implementasi kurikulum merdeka di sekolah lanjutan tingkat pertama. Strategi ini diterapkan untuk mengatasi beberapa permasalahan di kelas seperti pembelajaran yang monoton, keterbatasan sumber belajar, minimnya media pembelajaran, dan kurangnya minat belajar siswa. Kegiatan ini bertujuan untuk meningkatkan kemampuan guru dalam mengembangkan modul dan asesmen pembelajaran yang berbasis pada karakteristik peserta didik. Melalui pelatihan ini guru-guru dapat menghasilkan modul ajar yang dikembangkan sendiri sehingga dapat diimplementasikan dalam pembelajaran di kelas. Untuk mencapai tujuan tersebut, tim abdimas Pascasarjana Universitas Negeri Medan telah merancang tahapan kegiatan mulai dari persiapan, pelaksanaan pelatihan, pendampingan, evaluasi dan perbaikan. Berdasarkan metode yang diterapkan telah diperoleh hasil kegiatan berupa modul ajar dan asesmen dari setiap guru mata pelajaran. Modul dan asesmen pembelajaran tersebut disusun berdasarkan kemampuan awal dan karakteristik siswa sehingga berdampak pada peningkatan hasil belajar, keterampilan berpikir tingkat tinggi (HOTS) dan motivasi siswa dalam mengikuti pembelajaran. Modul dan asesmen tersebut telah menjadi perangkat pembelajaran yang digunakan guru dalam melaksanakan pembelajaran setiap hari di dalam kelas.

Abstract

This research examines how conceptual comprehension, mathematical reasoning, and problem solving affect computational thinking. 122 students from class XI SMA Negeri 1 Pematang Siantar were given essay assessments on conceptual comprehension, mathematical reasoning, problem solving, and computational thinking. AMOS version 21 was used to analyze the test using Structural Equation Modeling (SEM). This study found that conceptual understanding, mathematical reasoning, and problem solving have a positive and significant effect on computational thinking ability with a contribution of 0.528. This means that 52.8% and 47.2% of computational thinking abilities are built by these three abilities, depending on other variables.

Abstract

The very rapid development of technology is slowly appearing in the world of education. Educational games are a form of multimedia that packages learning programs in the form of games, so besides being games, they are also educational. The use of game education technology as an interactive learning medium is one of the right ways to improve students' mathematical creative thinking skills. This educational game is expected to eliminate the feeling of boredom and fear of learning mathematics and can facilitate the learning process on geometry material for Senior High School (SMA)/Islamic Senior High School (MA). This study aims to develop an Android-based educational game that can be operated on various smartphones with the Android operating system and to test the feasibility of using adventure games as a medium for learning geometry. This game can be used as an alternative medium for learning geometry in changing conventional learning methods to learning game simulations, so as to improve students' mathematical creative thinking abilities, because in educational games it has elements of challenge, accuracy, reasoning and ethics. The methodology used in this research is the research development method or Research and Development (R & D) using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model with the following activity stages: (1) Analysis, gathering information; (2) Design, designing multimedia-based animation media and validating media designs; (3) Development, improvement of media design; (4) Implementation, media testing; (5) Evaluation, product revision.
