Abstract

This study aims to evaluate the differences in problem-solving abilities among students with low, moderate, and high motivation levels, as well as to compare the problem-solving abilities between students who use and do not use e-worksheet. Data analysis was conducted using prerequisite tests, t-test, and ANOVA hypothesis test. The results of the study indicate that there are differences in problem-solving abilities among students with low, moderate, and high motivation levels. Additionally, there are differences in problem-solving abilities between students who use and do not use e-worksheet. However, no significant interaction was found between the use of e-worksheet and learning motivation on students' problem-solving abilities.

Abstract

This study investigates the effectiveness of E-Worksheets in enhancing students' problem-solving skills, with a specific focus on self-directed learning, in the topic of ratios. The research examines the impact of technology-based learning tools on students' ability to solve problems and explores the relationship between self-directed learning and problem-solving abilities. The study employs a control group design, comparing the performance of students using E-Worksheets with those in a control group. The findings indicate that the use of E-Worksheets significantly improves students' problem-solving skills compared to the control group. Moreover, the analysis reveals a positive association between students' level of self-directed learning and their problem-solving abilities. These findings support the integration of technology in the learning process to create interactive and engaging experiences that foster problem-solving skills. The study emphasizes the importance of cultivating students' self-directed learning and recommends strategies for educators to promote independent problem-solving and collaboration among students. The implications of this research contribute to the understanding of the role of E-Worksheets and self-directed learning in enhancing problem-solving skills and provide valuable insights for future research and educational practices.

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

The integration of technology in education has introduced innovative tools to enhance learning experiences, including the use of educational games. This study examines the impact of the educational game Quizizz on the motivation and mathematics performance of eighth-grade students. The research utilized a quasi-experimental design with a Non-Equivalent Control Group Design. The sample was selected using cluster random sampling, consisting of 25 students from class VIII B as the control group and 25 students from class VIII C as the experimental group. Data were collected through questionnaires and mathematics tests. The analysis employed an Independent Sample t-Test to evaluate the effect of Quizizz on student motivation and a Mann-Whitney test to assess its impact on mathematics learning outcomes. The results revealed a significant positive effect of Quizizz on motivation, with a p-value of 0.042 (p < 0.05). Similarly, Quizizz significantly improved mathematics learning outcomes, as indicated by the Mann-Whitney test (p = 0.047). These findings suggest that Quizizz is an effective interactive learning tool that enhances both student motivation and academic achievement in mathematics. Thus, incorporating Quizizz into classroom activities can be a strategic approach to fostering student engagement and improving learning outcomes in mathematics.

Abstract

In the context of improving student engagement and interest in mathematics, innovative teaching methods are essential. This study aims to examine: (1) students' interest in learning mathematics using a conventional teaching model, (2) students' interest in learning mathematics using a Flippity-based Teams Games Tournament (TGT) model, and (3) the effect of the Flippity-based TGT model on students' interest in learning mathematics. The research employs an experimental design with a quasi-experimental approach using a nonequivalent control group design. The population consists of eighth-grade students at SMP Muhammadiyah 4 Yogyakarta, and cluster random sampling was used to select the sample. Data were collected through observation, questionnaires, and documentation. Data analysis was conducted using a t-test. The results indicated that students' interest in mathematics with the conventional model had an average score of 68.04, categorized as average, while the TGT-based Flippity model showed an average score of 72.72, categorized as good. The hypothesis test revealed a significant effect of the Flippity-based TGT model on students' interest in learning mathematics, with a p-value of 0.036 (p < 0.05). Based on these findings, it is recommended that mathematics teachers consider implementing the TGT model with Flippity media, as this combination positively impacts students' interest in mathematics learning.
