Abstract

This study aims to determine the effectiveness of brain-based learning on improving students' mathematical logical thinking abilities. The research uses a quantitative approach with a quasi-experimental method, specifically a non-equivalent control group design. The population in this study consists of all eighth-grade students at SMP Negeri 2 Karawang Timur. The sample includes two classes: Class VIII-G as the experimental group and Class VIII-J as the control group. The sampling technique used is cluster random sampling. Data collection was carried out using instruments in the form of pre-test and post-test. The instrument used in this study was a test designed to measure students' mathematical logical thinking abilities. There are two variables in this study: the use of the brain-based learning model as the independent variable and mathematical logical thinking ability as the dependent variable. The results of the study show that the post-test scores of the experimental class were higher than those of the control class, with N-Gain values of 0.50 and 0.45, respectively. The t-test for the difference in mean N-Gain scores showed a significance value (Sig. 2-tailed) < 0.05, namely 0.014, indicating that there was a significant difference in improvement between the control and experimental classes. Additionally, Cohen's d effect size (standardized mean difference) was 0.31, suggesting that the brain-based learning model had a moderately meaningful practical impact on improving students' mathematical logical thinking abilities. Thus, the brain-based learning model is proven to be effective both statistically and practically in enhancing students’ mathematical logical thinking skills.

Abstract

In junior high school mathematics, exponents are a fundamental topic that underpins the understanding of more advanced concepts such as logarithms and exponential equations. However, many students still struggle to fully grasp this concept, leading to various forms of misconceptions. Using a systematic literature review approach, this study aims to examine the types of misconceptions, their causes, and the implications for teaching and learning. The literature search was conducted through Google Scholar and Dimension AI databases using specific keywords and inclusion criteria, namely: articles discussing the analysis of misconceptions in teaching exponents at the junior high school level, published between 2020 and 2025, and sourced from indexed national and international journals. The selection process yielded four articles that met the criteria and were relevant for further analysis. The review findings indicate that the types of misconceptions found among students include generalization, notation, overspecialization, and mathematical language. The causes of these misconceptions are classified into internal factors (such as incorrect preconceptions and a tendency to memorize without understanding), external factors (such as non-contextual teaching approaches and lack of visual media), and differences in students' academic abilities. These findings imply the need for diagnostic assessment, meaningful learning, the use of concrete media, and differentiated instruction strategies tailored to students' needs to minimize misconceptions and enhance conceptual understanding of exponents.

Abstract

This study aims to analyze the influence of student participation and mathematics achievement on students' mathematical resilience at the elementary school level. The research design employs a quantitative approach with an explanatory design to examine the causal relationships between the independent variables (participation and achievement) and the dependent variable (resilience). The participants in this study were 158 elementary school students from Mataram City, selected using convenience sampling. Data were collected through questionnaires to measure student participation, report card grades for mathematics achievement, and a resilience questionnaire tailored for elementary school students. Data analysis was performed using normality tests, non-parametric regression, and RT-ANCOVA. The results indicate that student participation significantly influences mathematical resilience, while mathematics achievement does not have a significant effect. Gender and geographic factors also affect mathematical resilience, with female students and those from urban areas exhibiting higher resilience compared to male students and those from mountainous or coastal areas. This study highlights the importance of active student involvement in mathematics learning and the need to address gender and geographic disparities in mathematics education. The findings offer insights into educational policies to support the development of students' resilience in mathematics.

Abstract

This study aims to examine the effect of implementing Culturally Responsive Teaching (CRT) on the mathematics learning motivation of eighth-grade students at SMP Negeri 2 Palu. The problem stems from students’ low motivation, which leads to difficulties in understanding concepts, weak problem-solving skills, and low learning outcomes. This research employed Classroom Action Research (CAR) using the Kemmis and McTaggart model, carried out in two cycles with 32 students as the subjects. Data were collected through a Likert-scale motivation questionnaire and classroom observation. The results showed an increase in learning motivation from 61% (moderate category) in the pre-cycle, to 66% (moderate category) in the first cycle, and 76% (high category) in the second cycle. Improvements were evident in several indicators, including the desire to succeed, learning drive, future aspirations, recognition in learning, engaging learning activities, and a supportive classroom environment. Thus, the implementation of CRT was proven to enhance students’ mathematics learning motivation through contextual, meaningful, and culturally relevant instruction, while also highlighting the importance of integrating students’ cultural backgrounds and real-life experiences as strategies to foster motivation and active participation in learning.

Abstract

In this study, a descriptive qualitative approach was employed, with data collection tools consisting of tests, interviews, and document analysis. The subjects involved were three seventh-grade students from class VII E at SMPN 1 Sanankulon, selected based on test results and recommendations from their mathematics teacher, representing three levels of cognitive ability: high, moderate, and low. After analyzing the collected data, it was found that each student demonstrated potential for critical thinking, with varying levels of achievement influenced by their conceptual understanding and ability to process information. The assessment of critical thinking skills was based on Facione’s four indicators: interpretation, analysis, evaluation, and inference. The findings showed that: (1) Students with high ability were able to solve each problem while clearly addressing all four of Facione’s indicators and applying accurate strategies and calculations. (2) Students with moderate ability did not fully demonstrate all four indicators but showed sufficient computational skills and arrived at correct answers, although they were not thorough in documenting their solution processes. (3) Students with low ability failed to meet all four indicators comprehensively, were less meticulous in presenting their solutions, and made frequent errors in their calculations.
