Abstract

The use of GeoGebra in mathematics education positively impacts students' mathematical abilities. This meta-analysis examines its overall effectiveness using 10 studies selected from Google Scholar and Scopus based on inclusion criteria. Data were analyzed using RStudio, revealing an overall effect size of 1.31, indicating a highly positive impact. The study also analyzed variability with four moderator variables: education level, publication type, control class type, and mathematical ability. Results show that GeoGebra significantly enhances mathematical abilities based on publication source and control type but is not influenced by education level. Notably, GeoGebra effectively improves students' conceptual understanding of mathematics, making it a valuable tool for enhancing mathematical skills in education. These findings emphasize the significant role of GeoGebra in fostering students' mathematical comprehension.

Abstract

Students' failure to grasp mathematical concepts can impede their mastery of learning standards, necessitating remedial efforts often constrained by time. Video-based remedial learning emerges as an innovative solution to enhance learning effectiveness. This study assessed the improvement in student outcomes following video-based remedial learning. Using an experimental pretest-posttest design, the study involved 100 Year 11 and 12 students from a public high school in Sukamakmur, Aceh Besar, Indonesia. Data analysis, via N-Gain score and t-tests, revealed three key findings: (1) a notable improvement in student outcomes after video-based remedial learning on trigonometric comparisons, (2) a greater enhancement in science classes compared to social studies classes, and (3) a higher increase in Year 12 compared to Year 11. The results affirm that video-based remedial learning positively impacts students' understanding of trigonometric functions

Abstract

Many ethnomathematical studies focus on Indonesian culture, particularly traditional dwellings, although research into the mathematical notions of the Tajug House is sparse. There has been no previous research that examines the Tajug House form the aspect of geometry. Tajug houses are becoming increasingly rare. Nowadays students are less familiar with traditional house types. As a result, this study investigates the mathematical principles found in traditional Tajug houses in Java, and how these notions might be integrated into educational curriculum to conserve cultural heritage while also improving mathematics learning. This study used an ethnographic approach, to investigates the Tajug House's design through a literature review, expert interviews, and observations. The data obtained were analyzed based on mathematical and Tajug House knowledge by author to see the existence of mathematical concepts in the tajug house. The findings reveal significant geometric concepts, including plane geometry (square, triangle, trapezoid), solid geometry (cuboid), and geometric transformations (reflection). Square found in the base of the house, triangle found in the side of the roof, and trapezoid found in the base of pillar. Cuboid found in the pillar. Reflection found in the base of the house. These results suggest that Tajug Houses can effectively become one of the learning media to geometry subject in schools, demonstrating practical ethnomathematics applications. The learning process can utilize the GeoGebra application. By linking cultural heritage with mathematical education, this research promotes a deeper understanding of both subjects. Future studies should evaluate the effectiveness of Tajug House-based learning in improving students' math comprehension and cultural appreciation.

Abstract

This research is motivated by the results of observations which show that the results of the three-dimensional daily assessments and end-of-semester assessments are still not optimal. This is influenced by several factors, especially the student's interest in learning in class. They still have difficulty visualizing the three dimensions so in calculating the questions given, they still experience difficulties completing them. Three-dimensional material requires a good understanding of the shapes of three-dimensional space and related concepts. Therefore, the Augmented Reality (AR) feature is needed in the Geogebra application. This research aims to analyze students' learning interests by using the Augmented Reality (AR) feature in the Geogebra application. This research used a qualitative approach where the research subjects were 61 students consisting of 33 students in class XII IPA 1 and 28 students in class XII IPS 1 at SMAIT Raudhatul Jannah Cilegon. The research results show that the presentation of each indicator on the student interest scale questionnaire has an average of 80.19%, which means that almost all students already have an interest in learning three-dimensional material using the Augmented Reality (AR) feature in the Geogebra application. It is hoped that other researchers can develop the results of this research, as well as improve the quality of learning, especially in mathematics learning with the help of the Geogebra application to increase insight.

Abstract

The critical problem in this research is the lack of instructional strategies that simultaneously enhance literacy and numeracy skills while addressing students' diverse learning needs. While the Problem Based Learning model fosters problem-solving, its implementation often overlooks individual differences, making its integration with differentiated instruction crucial and challenging. One of the mathematical skills that students must have is literacy numeracy skills. However, based on initial observations at one of the public senior high schools in Kuningan, students' literacy and numeracy abilities are still low. This study aims to examine the effectiveness of the Integrated Problem Based Learning Differentiated Instruction model in improving high school students’ literacy and numeracy skills. The research employed an experimental method with a one-group pre-test and post-test design involving 36 class XI students. Data were collected through literacy numeracy tests administered before and after the intervention. Data analysis was conducted using N-gain to measure the improvement in students' literacy numeracy ability. The research results were obtained from test results N-Gain, with scores of 0.56 (medium category) and an increase percentage of 56.05%. Students show better abilities in understanding, interpreting, and analyzing problem-based questions related to mathematical concepts
