Abstract

Rendahnya kemampuan berpikir kritis siswa merupakan salah satu masalah yang harus diatasi, khususnya menghadapi Era Revolusi Industri 4.0 dan pembelajaran abad 21. Salah satu cara meningkatkan kemampuan berpikir kritis siswa adalah melalui pembelajaran Realistic Mathematics Education (RME) berbasis Lesson Study for Learning Community (LSLC). Tujuan penelitian ini adalah untuk mendeskripsikan peningkatan kemampuan berpikir kritis siswa dalam pembelajaran materi SPLDV menggunakan pendekatan RME berbasis LSLC. Penelitian ini menggunakan jenis penelitian Quasi Eksperimen, dengan menggunakan satu kelas eksperimen dan satu kelas kontrol. Subjek dalam penelitian ini adalah 50 siswa kelas VIII SMP Al-Ikhlash Lumajang. Pembelajaran RME berbasis LSLC dikenakan pada 25 siswa kelas VIII A sebagai kelas eksperimen dan pembelajaran konvensional dikenakan pada 25 siswa kelas VIII B sebagai kelas kontrol. Hasil penelitian menunjukkan bahwa penerapan model RME berbasis LSLC mampu meningkatkan kemampuan berpikir kritis siswa pada materi SPLDV lebih baik dibandingkan dengan pembelajaran konvensional. Tingkat berpikir kritis siswa pada kelas eksperimen lebih besar dari kelas kontrol terjadi pada tingkat berpikir kritis level 3 (TBK 3) dan level 4 (TBK 4). Pada kedua level tersebut, kelas eksperimen mencapai 40% dan 24%, sedangkan kelas kontrol mencapai 32% dan 20%. Dari hasil ini disarankan kepada guru matematika hendaknya menerapkan pembelajaran RME berbasis LSLC dalam upaya meningkatkan kemampuan berpikir kritis siswa.

Abstract

An open-ended problem in learning mathematics is a problem with more than one answer or method of solving. In solving open-ended problems in learning mathematics, one of the abilities students must use is decision-making ability. Each student has a variety of capacities, so this study aims to determine students' decision-making abilities in solving open-ended problems in learning mathematics. The type of research used is descriptive qualitative research. The subjects of this study were four students with different numbers of correct answers in working on open-ended problems. Data collection was carried out using tests and interviews. The results showed that (1) the decision-making ability of the subject who answers correctly for both problems is complete because they fulfill all indicators, the subject can identify goals, make decisions, evaluate the results of determination, and present and remember between problems with things known to the problem and related to decisions that have been taken correctly; (2) decision-making ability for subjects with wrong answers on one number or two numbers is incomplete because they only fulfilled two indicators, the subject can identify goals, make decisions, is less able to evaluate decision results and present and remember between problems with things known to the problem, and related to decisions that have been taken with correct. Mathematics teachers should often reinforce students to practice operating integers because it is a prerequisite for learning mathematics at the middle and high school levels.

Abstract

This study aims to develop Realistic Mathematics Education (RME) learning tools integrated with agricultural activities, fulfilling the criteria of valid, practical, and effective to improve numeracy skills, particularly in the topics of direct and inverse proportionality. This study used the research and development with the Plomp model, comprising three phases. The first phase, preliminary research, involved 26 teachers and prospective teachers. The second phase, development or prototyping, engaged three experts and three students. The third phase, assessment, was conducted through trial testing with 31 participants in the experimental class and 31 participants in the control class. Data collection techniques included questionnaires, surveys, observations, tests, and interviews. Data processing was conducted using descriptive statistics. The results of the study indicate that the developed RME learning tools integrated with agricultural activities fulfills the criteria of valid, practical, and effective. The validity criteria were achieved with scores of 3.77 for the teaching module, 3.81 for the LKPD, 3.84 for the learning achievement test, and 3.87 for the instruction manual. The practicality criteria were met with a learning implementation rate of 95% (very good), and student activity reaching 84.9% (active). Additionally, student and teacher response questionnaires showed positive feedback, with scores of 95.48% and 100%, respectively. The effectiveness criteria were achieved with an average N-Gain score of 0.65 (moderate) and the experimental class achieved higher average scores than the control class. This study implies that RME integrated with agricultural activities can be recommended for mathematics teachers to support numeracy teaching.
