Student academic performance is a key indicator of successful study program management. Detection of academic performance can help study program managers monitor and take proactive action against students who are potentially experiencing difficulties. Machine learning can be a solution to this challenge by assisting in the classification and detection of students' academic abilities. Machine learning techniques have proven to be very effective in analyzing complex data and uncovering hidden patterns that are difficult to detect by humans. This research aims to explore the implementation of machine learning algorithms in detecting students' academic performance, especially in the Mathematics Education Study Program at Nias University. With the advancement of technology, machine learning has proven to be effective in classifying data and detecting hidden patterns that traditional methods cannot identify. This research uses the Support Vector Machine (SVM) algorithm to predict student academic performance based on a dataset collected from student primary data. The dataset includes factors such as GPA, attendance, participation, and use of learning resources. The analysis results show that the SVM model used has an accuracy of 77.59%, with a bias that is more inclined to the class of students with good academic performance. The results of this study are expected to make a practical contribution in the development of more effective learning methods and personalization of academic interventions in higher education.

Mathematical concept understanding is an essential ability that students must master in mathematics learning to enable them to comprehend and apply mathematical ideas effectively. However, in reality, many students experience difficulties in understanding mathematical concepts due to low learning motivation, which ultimately affects their learning outcomes. This study aims to examine the relationship between learning motivation and mathematical concept understanding among Grade XII students. This research employed a quantitative approach with a correlational research design. The population consisted of 90 Grade XII students, and the sample was selected using purposive sampling from class XII IPA-1. The research instruments included a learning motivation questionnaire and a mathematical concept understanding test, both of which had been tested for validity and reliability. Data analysis techniques involved normality testing, homogeneity testing, and hypothesis testing using the Product Moment correlation method. The results showed that students’ learning motivation was categorized as high, with a percentage of 78.79%. Meanwhile, students’ mathematical concept understanding was mostly in the good and very good categories, with percentages of 51.52% and 27.27%, respectively. The hypothesis test indicated that the calculated t value (4.354) was greater than the t table value (2.040) at the 5% significance level. The correlation coefficient obtained was r = 0.616, with a coefficient of determination of 37.94%. These findings indicate that learning motivation is not the sole factor influencing students’ mathematical concept understanding; other internal and external factors also contribute.

This study addresses the limited use of technology-based instructional media and insufficient instructional time in mathematics learning. It aims to develop and evaluate Wordwall-based learning media in terms of validity, practicality, and effectiveness in improving students’ learning interest and achievement. The study employed a Research and Development design using the ADDIE model up to the evaluation stage. Participants included 32 eighth-grade students from SMP Negeri 3 Huruna and one mathematics teacher. Data were collected through expert validation involving three validators, student and teacher response questionnaires, and learning achievement tests. Data analysis combined descriptive qualitative analysis with quantitative analysis using percentage scores and pretest–posttest comparisons. The findings indicate that the developed media is valid in terms of content, language, and visual design; highly practical, as reflected by positive responses from more than 90 percent of students and teachers; and effective in improving learning interest, with an average increase of 25 percent, as well as learning outcomes, with an N-gain of 0.62 in the medium–high category. The novelty of this study lies in positioning Wordwall not merely as a gamification tool, but as an interactive learning medium systematically integrated within the ADDIE instructional design framework for mathematics learning. Theoretically, this study strengthens evidence on the role of gamification within instructional design. Practically, it offers teachers a viable strategy to address time constraints while enhancing student engagement and learning outcomes.
