This study evaluates the effectiveness of the Intensive Mathematics Class Program (IMCP) - an expository teaching intervention designed to mitigate mathematics learning loss among low-achieving 10th-grade students at Sekolah Global Mandiri Cibubur, Indonesia, following by the fact of widespread COVID-19 educational disruptions (affecting 90% of learners globally) and documented declines in national PISA mathematics scores. Using a purposive sampling technique, 18 students with the lowest performance (three from each class) were selected to participate in structured instruction on quadratic equations, assessed through a pretest–posttest design. Results indicated significant improvement, with mean scores increasing from 1.33 (SD = 1.14) to 6.61 (SD = 3.47). Non-parametric tests (Shapiro–Wilk W = 0.806, p = 0.002) confirmed data non-normality and the effectiveness of the intervention, further supported by a large effect size, ES = 0.86. Notably, 17 out of 18 students demonstrated score improvements, while only 1 student showed no improvement. These findings show that systematic expository teaching can effectively bridge learning gaps. The study shows the effect of the IMCP as the strategy for low-achieving students in the post-pandemic context. However, the study’s generalizability is limited by its small sample size and localized setting in Senior High School Global Mandiri Cibubur. In the future, the research recommends to expand participant diversity and sample size.

Kawung batik motif is one of Indonesia's cultural heritage that is full of philosophical and aesthetic meanings, and shows regular and symmetrical visual patterns. This research aims to analyze the geometric shapes in Kawung motif and identify the types of geometric transformations that form the pattern arrangement. The approach used in this research is descriptive qualitative method with geometric visual analysis technique. Data were obtained through documentation study of Kawung motif, visual observation of the pattern arrangement, and literature study related to geometric transformation theory. The results show that Kawung motifs contain four types of geometric transformations, namely translation (repetition of patterns horizontally and vertically), rotation (rotation of 90° and 180° towards the center point), reflection (reflection on the vertical and horizontal axes), and dilation (variation in the size of motif elements). Folding symmetry and rotating symmetry were also found to be part of the visual structure that reinforces the regularity of the motif. These findings show that the Kawung motif has a mathematical value that can be explained scientifically, in line with the principles of plane geometry. The conclusion of this study confirms that Kawung batik motifs can be utilized as contextual media in mathematics learning, especially for geometry transformation materials. Thus, the integration between local culture and science through this visual approach not only supports meaningful and applicable learning, but also becomes part of the strategy of cultural preservation through education

This study aims to investigate the effectiveness of digital educational games in increasing elementary school students’ interest in learning mathematics. Using a quasi-experimental design, the research involved two groups of fourth-grade students: one experimental group that received instruction through digital games and one control group taught using conventional methods. Data were collected through observation, questionnaires, and pretest-posttest measurements of students’ learning interest. The results showed that students in the experimental group experienced a significant increase in motivation and engagement compared to the control group. Digital games provided interactive and visually stimulating experiences that helped simplify abstract mathematical concepts and made learning more enjoyable. Furthermore, the games fostered collaborative learning and improved classroom dynamics. The findings support the integration of game-based learning in elementary mathematics instruction as a powerful tool to enhance students’ affective involvement and enthusiasm for learning. The study suggests that educators should consider incorporating digital games to create more engaging and student-centered learning environments.

This study aims to determine the effect of the discovery learning model with the help of quizizz paper mode media on increasing the average mathematics scores of grade 3 students of Segorotambak State Elementary School, Sedati District, Sidoarjo as an experimental group. The background of this study is the large number of students who have mathematics scores below the KKM (Minimum Completion Criteria). In this study, there are 2 population groups, namely Segorotambak State Elementary School as an experimental group using the discovery learning model with the help of quizizz paper mode and Pepe State Elementary School as a control group. This study uses a quantitative experimental research type with a pre-Experimental Design One-Group (Pretest-Posttest Design) research design. The population used was grade 3 of Pepe State Elementary School totaling 28 students and Segorotambak State Elementary School totaling 17 students. Data collection techniques in the form of giving an initial test (pre-test) before being given treatment and a final test (post-test). The data analysis technique used in this study was the results obtained from the pre-test and post-test scores of students using Shapiro Wilk. The results of this study showed a significant increase in the average value from 49.41, after using the Discovery Learning approach with the help of quizizz paper mode media to 70.58 or an increase of 21.17 so that research with the discovery learning approach through quizizz paper mode media at Segorotambak State Elementary School has been proven to be able to improve the mathematics scores of students in the experimental group.

This study aims to investigate the effectiveness of the GeoGebra application in enhancing students’ conceptual understanding of geometry at the junior high school level. Using a quasi-experimental design with a nonequivalent control group, the research involved two classes: one taught using GeoGebra (experimental group) and the other taught using conventional methods (control group). Both groups were given pre-tests and post-tests to assess their understanding of geometric concepts such as angles, shapes, and transformations. The results showed a significant increase in the post-test scores of the experimental group compared to the control group. Gain score analysis also revealed that students in the GeoGebra-assisted class achieved higher learning improvements. The use of GeoGebra helped visualize abstract geometric concepts in a dynamic and interactive way, which enhanced students’ engagement, comprehension, and motivation. The findings support the integration of interactive digital tools in mathematics instruction to foster meaningful learning and improve student outcomes, especially in abstract and visual topics like geometry.

The transformation of digital technology has resulted in fundamental changes in various sectors of life, including the field of education which is experiencing a significant paradigm shift. This study aims to explore the effectiveness of teacher professional education in improving educational technology skills in the digital era. Along with the rapid development of technology, teachers' ability to integrate technology into the learning process becomes a key element in creating innovative and relevant learning experiences. This study uses a descriptive qualitative approach involving teachers who have participated in the professional education program as the main participants. Data were obtained through in-depth interviews, observations, and document analysis of the education programs followed by the teachers. The results show that professional education substantially improves teachers' skills in utilizing various technological tools, including learning software, digital platforms and technology-based teaching techniques. In addition, the program also encourages the development of positive attitudes towards the use of technology as an integral part of learning. However, the effectiveness of the program is inseparable from challenges such as limited access to technology facilities, lack of follow-up training, and differences in the level of individual readiness to adopt technology. This study concludes that systematically designed professional education with a focus on educational technology has great potential to strengthen teachers competencies in the digital era. These results provide important implications for policy makers and education providers to continue developing needs-based programs, providing adequate infrastructure, and creating a supportive ecosystem that supports the application of technology in learning.
