Abstract

Tujuan penelitian ini adalah untuk mendeskripsikan dan mengkaji pengaruh pembelajaran dengan pendekatan explicit instruction dengan teknik scaffolding terhadap kemampuan penalaran matematis siswa SMP. Penelitian ini menggunakan metode kuasi eksperimen, desain yang digunakan adalah nonequivalent control grup design. Kelas eksperimen memperoleh pembelajaran dengan pendekatan exsplisit instruction dan kelas kontrol memperoleh pembelajaran konvensional. Populasi penelitian ini adalah seluruh kelas VII salah satu SMP Negeri di Cianjur. Adapun yang dijadikan sampel dalam penelitian ini dipilih sebanyak dua kelas dari tujuh kelas yang ada dipilih dengan teknik purposive sampling. Untuk memperoleh data hasil penelitian digunakan instrumen berupa tes kemampuan penalaran matematis dan angket. Pengolahan data peningkatan kemampuan penalaran matematis menggunakan uji mann-whitney. Berdasarkan analisis data, hasil penelitian menunjukkan bahwa peningkatan kemampuan penalaran matematis siswa yang menggunakan pendekatan explicit instruction dengan teknik scaffolding lebih baik dari pada peningkatan kemampuan penalaran matematis siswa yang menggunakan pendekatan konvensional, peningkatan yang terjadi ada pada kategori tinggi. Hasil angket menunjukkan bahwa sikap siswa terhadap pembelajaran matematika menggunakan pendekatan explicit instruction dengan teknik scaffolding adalah hampir seuruhnya positif. Kata Kunci: Explisit Instruction, Scaffolding, Kemampuan Penalaran Matematis.

Abstract

Students' mathematical investigation ability is not only influenced by cognitive knowledge, but also by affective factors such as mathematical disposition and self-esteem. This study aims to analyze the effect of mathematical disposition on students' mathematical investigation ability, analyze the effect of self-esteem on students' mathematical investigation ability, and analyze the effect of mathematical disposition and self-esteem on students' mathematical investigation ability. This study uses a quantitative approach. The population of the study was 49 students of class XI of a private high school in Cianjur Regency in the 2024/2025 academic year. The sample in this study was class XI-1 selected by purposive sampling. The research instruments were mathematical disposition and self-esteem questionnaires, as well as students' mathematical investigation ability tests on circle material. In addition, interviews were conducted with several students to strengthen the results of the mathematical investigation test. The data analysis techniques used included simple linear regression tests and multiple linear regression tests, by first ensuring that the classical assumptions were met. The results of the study showed that there was a significant influence between mathematical disposition and mathematical investigation ability of 40.2%. Meanwhile, self-esteem did not have a significant effect on mathematical investigation ability, with a contribution of 18.7%. Simultaneously, mathematical disposition and self-esteem had a significant effect on students' mathematical investigation ability, with a contribution of 31.6%. This finding emphasizes the importance of strengthening mathematical disposition in learning to improve students' mathematical investigation ability

Abstract

Mathematics is a basic science that is essential for mastering other sciences and continues to develop to meet the demands of the 21st century. Meaningful mathematics learning requires a contextual and technology-based approach. Kurikulum Merdeka is a government effort to address this challenge. However, obstacles remain in its implementation, such as teachers' lack of understanding of the learning modules and students' understanding of the material. Therefore, this study aims to develop a Geometry Transformation e-module using the Contextual Teaching and Learning (CTL) model in the Ruang GTK with the assistance of GeoGebra, which has been tested for its feasibility and practicality. This study uses a Research and Development (R&D) approach with the ADDIE model, through five stages: analysis, design, development, implementation, and evaluation. The research subjects consisted of three experts in material, media, language, and mathematics learning for the feasibility test and three mathematics teachers for the practicality test. The instruments used included an observation sheet, a validation sheet, and a practicality sheet. The developed e-module consists of four sub-chapters: Translation, Reflection, Rotation, and Dilation. This e-module also includes flowcharts, prerequisite materials, learning activities, teaching materials, learning media, GeoGebra, Student Worksheets (LKPD), and assessments. The study results showed that this e-module was highly feasible with a score of 85.14% and very practical with a score of 89.33%. This module is easily accessible and supports contextual and technology-based learning

Abstract

This study aims to analyze the influence of learning independence and self-efficacy on students’ mathematical understanding ability based on Kinach’s theory. This study employs a quantitative approach with data analysis techniques consisting of simple linear regression and multiple linear regression. The study population includes all 10th-grade students at state Islamic senior high schools (MA Negeri) in Cianjur Regency, with a sample of 34 students from class XA selected through purposive sampling. The instruments used consist of a mathematical understanding ability test based on Kinach’s theoretical indicators in the topic of Arithmetic Sequences and Series, as well as questionnaires on learning independence and self-efficacy. The data were analyzed using simple and multiple linear regression tests, preceded by prerequisite tests including normality, linearity, heteroscedasticity, and multicollinearity. The results show that learning independence has a positive and significant influence on students’ mathematical understanding ability based on Kinach’s theory, with a contribution of 36.3%. Likewise, self-efficacy has a positive and significant influence, contributing 69.4%. Furthermore, learning independence and self-efficacy simultaneously have a significant influence on students’ mathematical understanding ability based on Kinach’s theory, with a combined contribution of 69.7%. These findings indicate that the higher the students’ levels of learning independence and self-efficacy, the better their mathematical understanding ability as conceptualized in Kinach’s theory.
