Abstract

Terdapat perubahan paradigma pendidikan di Indonesia, yaitu pendidikan yang memfokuskan pada pendekatan deep learining (pembelajaran mendalam). Pendekatan pembelajaran mendalam ini tidak hanya berorientasi pada peningkatan hasil belajar tapi juga pada pembelajaran yang nyaman. Dalam prakteknya, hingga saat ini sekolah lebih menitikberatkan pada hasil akhir belajar berupa nilai, peringkat, dan kelulusan dan cenderung mengambaikan kenyamanan belajar. Padahal, kenyamanan belajar adalah langkah awal yang mepengaruhi peningkatan hasil belajar siswa. Oleh karena itu, model pembelajaran selayaknya tidak hanya berfokus pada peningkatan hasil belajar tapi juga kenyamanan belajar siswa. Selama ini model pembelajaran yang direkomendasikan di sekolah adalah discovery learning (penemuan), problem based learning (berbasis masalah), dan project based learning (berbasis projek). Sintaks model pembelajaran tersebut lebih cenderung pada peningkatan hasil belajar siswa dan belum sepenuhnya menciptakan kondisi kenyamanan belajar siswa. Model Pembelajaran AS-SAMAA adalah suatu model pembelajaran yang sintaksnya tidak hanya berfokus pada peningkatan hasil belajar tapi juga kenyamanan belajar siswa. Artikel ini akan menjelaskan apa dan bagaimana Model Pembelajaran AS-SAMAA itu?

Abstract

Computational thinking (CT) is a key competency in 21st-century mathematics education. However, Indonesian students still face challenges in decomposition, abstraction, and algorithmic reasoning due to learning resources dominated by single-solution problems. This study developed and evaluated a mathematics module based on open-ended problems to enhance students’ CT skills in quadratic functions. The research adopted an R&D approach using the ADDIE model, including analysis, design, development, implementation, and evaluation. The process involved needs, curriculum, and learner analyses, followed by expert validation, practicality testing, and effectiveness evaluation. Three experts validated the module, while teachers and students assessed its practicality. Effectiveness was tested using a quasi-experimental pretest–posttest control group design involving 61 high school students. Data were analyzed using descriptive statistics, N-Gain, and inferential tests. Results showed the module was valid, practical, and effective in improving CT skills. The experimental group achieved significantly higher N-Gain (p < 0.05) than the control group, with abstraction and pattern recognition showing the greatest improvement.

Abstract

This study aims to determine the process and results of developing scientific-based mathematics learning worksheets that meet valid and practical criteria and test the developed worksheets' validity, practicality, and effectiveness. This research and development refer to the steps of Borg and Gall. The research subjects were grade VIII students of the Qur'an Science Middle School Minhajuth Thullab Pekalongan for the 2022/2023 academic year: data collection techniques using interviews, problem-solving ability tests, and questionnaires. The results showed that the LKPD teaching materials developed were categorized as valid (fit for use) based on the assessment of media and material expert validators. In addition, the developed scientific-based LKPD is also categorized as practical based on student assessments and responses from the mathematics teacher. Based on hypothesis testing and proportions, the scientific-based LKPD can improve problem-solving skills, but it is not yet effective because the proportion of students with good category problem-solving abilities is not more than 60% of the total number of students.
