Abstract

Pemahaman konsep matematis adalah kemampuan siswa untuk memahami konsep-konsep matematika secara mendalam dan dapat menerapkan konsep tersebut dalam menyelesaikan masalah matematis dalam kehidupan sehari-hari. Salah satu faktor untuk menunjang pemahaman konsep matematis siswa dengan memanfaatkan teknologi informasi internet dengan bijak dan tepat oleh siswa. Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh signifikan antara pemanfaatan teknologi informasi internet terhadap pemahaman konsep matematis siswa SMP Negeri 9 Kota Palu kelas VIII. Jenis penelitian ini adalah penelitian kuantitatif. Sampel dalam penelitian ini berjumlah 60 orang yang terdiri dua kelas dan dari 246 populasi total dari delapan kelas. Teknik pengambilan sampel menggunakan Random Sampling. Instrumen yang digunakan berupa angket pemanfaatan teknologi informasi internet dan tes pemahaman konsep matematis. Temuan hasil dari penelititian ini bahwa terdapat pengaruh signifikan antara pemanfaatan teknologi informasi internet terhadap pemahaman konsep matematis siswa SMP Negeri 9 Kota Palu kelas VIII yang mana nilai R2 0,420 atau bahwa pemanfaatan teknologi informasi internet berkontribusi sebesar 42% terhadap pemahaman konsep matematis siswa adapun 58% pemahaman konsep matematis siswa dipengaruhi oleh faktor lainnya. Kata kunci: pengaruh, teknologi informasi, pemahaman konsep, penerapan, kemampuan matematis

Abstract

This study aims to analyze the errors of ninth-grade students at SMP Negeri 5 Palu in solving word problems involving arc length and sector area using the Newman procedure, from a cognitive perspective. The subjects in this study were 26 ninth-grade students in the 2024/2025 academic year. Subjects were recruited using the GEFT test. Data were analyzed using the Newman procedure to identify error types. Data collection techniques included the GEFT test, written tests, and interviews. The results showed that both FI and FD students made no errors in reading and understanding the problems. FI students were more thorough in the transformation and process skills stages, but experienced difficulties in the final writing due to time constraints. Meanwhile, FD students made errors in transformation and process skills, particularly in entering incorrect radius values ​​into formulas, as well as errors in the final writing. Cognitive style influenced the types of errors made by students. FI students were more able to solve problems independently, while FD students required more guidance.

Abstract

This study aimed to examine the effectiveness of the Problem-Based Learning (PBL) model assisted by GeoGebra on students’ mathematical literacy skills in solid geometry. The research employed a quantitative approach using a quasi-experimental design with a pretest-posttest control group design. The population consisted of ninth-grade students at a junior high school in Palu, and the sample was selected using cluster random sampling. Data were collected through essay tests to measure students’ mathematical literacy skills. Data analysis was conducted using the independent sample t-test and N-gain analysis at a significance level of 0.05. The results showed that the Sig. (2-tailed) value was 0.001, indicating a statistically significant difference between the experimental and control groups. The average N-gain score in the experimental class was 0.46, which falls into the moderate category and is higher than that of the control class, which was 0.15 in the low category. These findings indicate that the Problem-Based Learning (PBL) model assisted by GeoGebra is effective in improving students’ mathematical literacy skills in solid geometry and can be used as an alternative instructional approach in mathematics learning.

Abstract

Learning achievement in mathematics at the university level is influenced by various internal factors, including students’ beliefs in their abilities and their capacity to regulate learning processes. This study aims to examine the effects of self-efficacy and self-regulation, both individually and simultaneously, on university students’ mathematics learning achievement. An ex post facto quantitative design was employed involving 98 mathematics education students selected through proportional random sampling from a population of 130 students. Data were collected using self-efficacy and self-regulation questionnaires, as well as students’ grade point averages from first- and second-semester mathematics courses as indicators of learning achievement. The data were analyzed using simple and multiple linear regression after meeting classical assumption requirements. The results indicate that self-efficacy has a significant effect on mathematics learning achievement, contributing 15.5% of the variance, while self-regulation contributes 13.1%. When analyzed simultaneously, both variables significantly influence learning achievement with a combined contribution of 16.7%. Despite their statistical significance, the magnitude of these effects is relatively modest, suggesting that mathematics learning achievement is shaped by a combination of internal and external factors beyond self-efficacy and self-regulation alone. These findings imply that efforts to improve students’ mathematics achievement should not only focus on strengthening self-efficacy and self-regulation but also be supported by effective instructional strategies, learning environments, and institutional support. This study provides empirical evidence for mathematics educators to design learning interventions that integrate psychological and pedagogical approaches in higher education contexts.
