Abstract

This study aims to examine the relationship between breakfast habits and concentration in mathematics learning among seventh-grade students at MTs Al-Amin Kampung Pajak. The research employed a quantitative approach with a correlational design. Data were collected from 59 students using structured interviews, supported by teacher observations. The instrument underwent content validation by experts and was refined through a pilot test prior to implementation. The collected data were categorized into two nominal variables: breakfast habits (had breakfast vs. skipped breakfast) and concentration levels (high vs. low). The Phi coefficient (φ) was used for statistical analysis, supported by the chi-square test. The findings show a perfect correlation (φ = 1.0) between breakfast habits and learning concentration. All students who had breakfast exhibited high concentration, while all students who skipped breakfast demonstrated low concentration. The chi-square test yielded a value of 59, which exceeds the critical values at both 5% and 1% significance levels. These results indicate a statistically significant and strong positive relationship between breakfast consumption and mathematics learning concentration. The study concludes that breakfast is a critical external factor that enhances students’ cognitive readiness and supports academic success, particularly in mathematics.

Abstract

Mathematics is often perceived as an abstract and difficult subject by students, especially when learning topics such as Sequences and Series. The constructivist approach is considered effective in helping students build their own understanding through active involvement in the learning process, which in turn enhances their critical thinking skills. This study aims to quantitatively evaluate the impact of implementing a constructivist approach on students’ critical thinking skills in mathematics learning. A pre-experimental one-group pretest-posttest design was used, involving 32 tenth-grade students from the Industrial Computer and Network Engineering (TKJ Industri) program at SMKS Muhammadiyah 9 Medan in the 2024/2025 academic year. Data were collected using critical thinking tests administered before and after the learning intervention. Analysis involved descriptive statistics, normality tests, paired sample t-tests, and N-Gain calculations. Results indicated a significant improvement in students’ critical thinking scores, with the average score increasing from 54.06 to 77.19. The paired sample t-test yielded a significance value of 0.000 (p 0.05), and the N-Gain score was 0.50, indicating a moderate level of effectiveness. These findings suggest that implementing the constructivist approach positively impacts students' critical thinking development.

Abstract

The integration of digital technologies in mathematics education has become increasingly essential in the digital era. GeoGebra, an interactive mathematics software that combines algebra, geometry, calculus, and statistics, has been widely used to support visual and student-centered learning. This study aims to systematically review the literature on the effectiveness of GeoGebra in mathematics education by analyzing ten peer-reviewed articles published between 2020 and 2025. Using a qualitative descriptive design and systematic literature review method, the selected studies were examined in terms of their educational level, research design, and key findings.The results indicate that GeoGebra significantly enhances students’ conceptual understanding, visualization skills, problem-solving ability, and critical thinking. Moreover, it fosters greater engagement and motivation, particularly when integrated into interactive or constructivist learning settings. However, the review also identified challenges, including teacher readiness, technological infrastructure limitations, and a lack of focus on long-term and non-cognitive outcomes. These findings highlight the need for professional development, pedagogical alignment, and institutional support to optimize GeoGebra’s impact. Overall, GeoGebra holds strong potential as a transformative tool in mathematics instruction, provided its implementation is contextually and pedagogically supported.

Abstract

This study investigates the influence of daily study duration, task completion time, and gender on junior high school students' mathematics achievement using a Bayesian regression approach. The research was conducted at Sutomo Junior High School in Medan with a purposive sample of 19 seventh-grade students. Data were collected through a structured questionnaire and a mathematics achievement test, and analyzed using JASP software. Descriptive statistics were used to summarize student behavior, while Bayesian linear regression assessed the impact of the predictor variables. The results revealed that neither study duration nor task completion time significantly predicted mathematics achievement. Both variables showed a weak negative association with academic performance, suggesting that longer study or test-taking times do not necessarily yield better outcomes. The Bayes Factors indicated anecdotal or weak evidence in favor of the models. These findings highlight the limited predictive power of time-based behavioral indicators and emphasize the importance of study quality, learning strategies, and cognitive efficiency. The study contributes methodologically by demonstrating the utility of Bayesian analysis in small-sample educational research and offers insights for developing more comprehensive models of academic success

Abstract

This study aims to develop and assess the effectiveness of KOMAT (Mathematics Comic Media) integrated with a Problem-Based Learning (PBL) approach to improve students' motivation and learning outcomes in the topic of Systems of Linear Equations in Two Variables (SPLDV). The research employed the ADDIE development model consisting of analysis, design, development, implementation, and evaluation phases. The product was validated by material and media experts and tested on 28 eighth-grade students at SMP Negeri 42 Medan. Research instruments included expert validation sheets, pretest and posttest assessments, and student response questionnaires. The validation results showed that KOMAT was highly valid, with a score of 97% from material experts and 94% from media experts. Learning outcomes improved significantly, with average scores increasing from 59% (pretest) to 88% (posttest), yielding an N-Gain of 0.71 in the high category. Furthermore, student responses averaged 88%, indicating very good engagement and motivation. These findings suggest that KOMAT is a pedagogically effective and engaging media that supports conceptual understanding and learner motivation in mathematics. Future research is recommended to explore broader applications across topics and digital formats.

Abstract

The rapid growth of Indonesia’s sharia digital economy has created new financing models, particularly sharia crowdfunding, as an inclusive alternative for MSMEs. However, the current regulatory framework Financial Services Authority Regulation (POJK) No. 16/POJK.04/2021, remains general and has not fully incorporated sharia compliance principles. This study aims to analyze the strengthening of sharia crowdfunding law through the Maqasid al-Shari‘ah approach, emphasizing maslahah (public welfare), hifz al-m?l (protection of wealth), and ‘adl (justice). Using a normative legal method that combines statute and conceptual approaches, this research evaluates the extent to which POJK No. 16/2021 aligns with Islamic legal objectives. The findings show partial conformity, strong in procedural governance but weak in substantive justice and sharia supervision. The absence of a Sharia Supervisory Board (DPS) and explicit sharia audit requirements limits regulatory effectiveness. The study recommends reconstructing POJK No. 16/2021 through an integrated sharia governance system involving OJK, DSN-MUI, and halal certification bodies. Mandatory sharia audits, digital financial literacy, and value-based supervision are proposed to enhance ethical accountability. Such reform would harmonize technological innovation with the moral imperatives of Maqasid al-Shari‘ah, positioning Indonesia as a global pioneer in Islamic digital finance.

Abstract

Integral Calculus is a form of mathematics learning that can be applied in everyday life. One application is in calculating the volume of rotating objects. In this research, we combine integral concepts in calculus with the numerical and visualization capabilities provided by GeoGebra software. The aim of this research is to apply the concept of integral calculus in calculating the volume of a rotating object in the form of a ball. The method used is a qualitative descriptive method that uses literature studies to search for formulas and to construct spherical shapes to determine their volume. The experimental method is used to find manual calculation results on real objects. The research results show that the integral concept used in calculating the volume of a ball using software assistance in the form of the GeoGebra application can produce quite accurate results.
