Abstract

Mathematics is often perceived as a difficult subject due to the large number of formulas that students must understand and memorize. This condition can lead to learning difficulties and trigger mathematics anxiety, which may reduce students’ ability to retain mathematical concepts. This study aims to examine various effective strategies for memorizing mathematical formulas based on previous research. The research employed a qualitative approach using a literature review method involving 30 relevant scientific articles obtained from several academic databases. Data were collected through a literature study, while the analysis was conducted by identifying, comparing, and synthesizing findings from the collected literature. The results show that strategies for memorizing mathematical formulas can be categorized into four main groups: audio-musical and artistic strategies, digital technology and gamification innovations, cognitive strategies through mnemonics and kinesthetic tools, and structured drill methods. These strategies have been shown to improve memory retention, learning motivation, and students’ learning outcomes. The findings indicate that the application of creative and multisensory learning strategies can help students memorize mathematical formulas more effectively.

Abstract

Educational game media developed based on problem-based learning is one alternative designed to help students improve their mathematical literacy skills and understand sequences and series in a more interesting and interactive way. This study aims to examine the validity, practicality, and effectiveness of using media in mathematics learning. The type of research used is development research with the ADDIE research model. This study was conducted at MAN 1 Medan with class X-16 as the subject. The results showed that the use of educational game learning media could improve the mathematical literacy skills of class X-16 students. This was indicated by the results of subject matter expert validation with a percentage of 88% in the ‘highly valid’ category, as well as media expert validation results with a percentage of 89.9% in the ‘highly valid’ category. In addition, the students' response to the media reached 88.4% and was categorised as ‘very practical’, which was also supported by the N-Gain results on the mathematical literacy skills of class X-16 students with a result of 0.710, which falls into the high category, meaning that the educational game media developed is effective for use in learning the material on sequences and series

Abstract

This study aims to examine the basic concept of function limits in calculus and analyze their vital role as the main foundation in learning calculus. The research method employed is a literature review, analyzing various sources such as textbooks and scientific journal articles related to limit concepts, student misconceptions, and relevant pedagogical strategies. Data analysis was conducted qualitatively and descriptively to synthesize the relationship between the concept of limits, derivatives, and integrals. The results indicate that the limit is a fundamental concept that explains functional behavior and serves as the formal basis for defining derivatives as rates of change and integrals as area accumulation (Riemann sums). The study concludes that a strong conceptual understanding of limits is essential to avoid the dominance of mechanistic procedures and to help students master advanced calculus concepts systematically. It is suggested that calculus instruction should emphasize visual representation and mathematical interpretation, although this study is limited to a literature approach without empirical field data.

Abstract

Purpose - This study critically synthesizes research on the development of technology-based assessment instruments in secondary science education (junior and senior high school) through a structured Narrative Literature Review (NLR). This review therefore identifies instrument types, implementation contexts, research dimensions examined, and learning impacts, while highlighting gaps in equity, teacher readiness, and longitudinal outcomes.Methodology - Articles were systematically retrieved from Google Scholar and Mendeley within the 2015–2025 publication range using predefined keywords related to technology-based assessment and science learning. Inclusion criteria required peer-reviewed empirical studies focusing on secondary-level science and reporting instrument development or evaluation. Fourteen eligible articles were analyzed using structured content analysis, with emphasis on instrument characteristics, evidence of validity and reliability, implementation contexts, methodological approaches, and reported limitations.Findings - The synthesis indicates that research predominantly centers on Computer-Based Testing (CBT), Computerized Adaptive Testing (CAT), gamified assessments, two-tier diagnostic tests, and LMS-based e-portfolios. Overall, these instruments demonstrate satisfactory validity and reliability and effectively measure higher-order thinking skills and conceptual understanding. They also enhance student motivation and accelerate feedback processes. However, most evidence is based on short-term, small-scale implementations, with limited attention to equity issues, teacher readiness, and sustained learning effects.Contribution - This review integrates psychometric, pedagogical, and technological perspectives into a coherent analytical framework for technology-based assessment in science education. It clarifies existing research gaps and underscores the need for broader contextual validation, stronger methodological rigor, and the integration of learning analytics to ensure sustainable and evidence-based digital assessment practices.
