Abstract

Satuan pendidikan melalui Kurikulum Merdeka berkewajiban untuk memfasilitasi siswa dalam memaksimalkan potensi dan kemampuan individu setiap siswa, salah satunya melalui pembelajaran berdiferensiasi. Pembelajaran berdiferensiasi merupakan pembelajaran yang didasarkan pada kebutuhan siswa, baik kesiapan belajar siswa, minat belajar, dan profil belajar siswa. Akan tetapi, terdapat hambatan yang dialami oleh guru, khususnya guru Matematika SMP di kota Surakarta, dalam memahami pembelajaran berdiferensiasi, baik secara konsep maupun pelaksanaannya. Guru masih mengalami hambatan dalam menyusun alur dan proses pembelajaran berdiferensiasi. Untuk itu, dilakukan pelatihan implementasi pembelajaran berdiferensiasi yang melibatkan guru Matematika SMP di kota Surakarta sebanyak 20 orang. Adapun tahapan kegiatan yang dilakukan yaitu: (1) penyampaian materi mengenai kebijakan Kurikulum Merdeka dan pembelajaran berdiferensiasi; dan (2) perancangan pembelajaran matematika pembelajaran berdiferenisasi. Kegiatan pelatihan memberikan pemahaman kepada guru Matematika SMP kota Surakarta terkait pembelajaran berdiferensiasi, pada aspek konsep pembelajaran berdiferensiasi maupun merancang pembelajaran matematika dengan pendekatan pembelajaran berdiferenisasi melalui menggunakan kerangka backward design.

Abstract

Integers are one of the essential materials in mathematics, but provides its own difficulties for students, especially with regard to negative integers. This study aims to develop a hypothetical learning trajectory based on the results of the learning obstcale study. Specifically, the alleged learning trajectory is a conjecture on phase D students, namely Junior High School students based on the differentiation of the readiness aspects of high, medium, and low students. This study used development research with a didactical design research approach at the prospective analysis stage, namely analyzing the didactic situation before learning. The development results obtained a hypothetical learning trajectory based on the analysis of learning obstacle and literature review. Based on this, the hypothetical learning trajectory that is compiled consists of four stages starting from the concept of negative numbers, the concept of integers, counting operations on integers, and the properties of calculating operations on integers and their application. In addition to these four stages, the alleged learning trajectory also emphasizes the meaning of the minus sign as a prerequisite concept in integers. The integration of didactical situations in the hypothetical learning trajectory emphasizes the diversity of didactical situations towards students’ abilities as a form of differentiated instruction, especially in differentiating content.

Abstract

The absence of a standardized instrument contextualized for Indonesian students was a primary problem motivating this research, which aimed to develop and validate the Mathematics Learning Motivation Scale (MLMS) for junior high school students. This study employed a systematic instrument development process. The scale was constructed based on a synthesis of motivation theories, specifically operationalizing four key aspects: choice of tasks, effort, persistence, and self-confidence. These aspects were formulated into 30 Likert-scale items. The validation method included content validity, which was established through expert judgment from two education experts, and construct validity. The subjects for the validation trial were 31 eighth-grade students from a junior high school in Boyolali. The primary instrument used was the 30-item MLMS questionnaire itself. Data analysis was performed using SPSS version 22. The results from the Pearson product-moment correlation showed that all 30 items were valid, with each item's rcalculated score exceeding the rtable value of 0.355 at a 5% significance level. Furthermore, the reliability analysis reported a Cronbach's Alpha coefficient of 0.917, demonstrating very high internal consistency. It was concluded that the developed MLMS is a valid and highly reliable instrument, suitable for objectively measuring mathematics learning motivation in this specific student context.
