Abstract

GeoGebra-assisted Discovery Learning offers a promising solution to the challenges of mathematical literacy. This model is not only student oriented but also encourages learners to actively and independently construct mathematical concepts and connect them to real-life experiences. This study aimed to examine the effectiveness of GeoGebra based Discovery Learning in enhancing students’ mathematical literacy and to assess their literacy level after its implementation. An experimental method with a one-group pretest–posttest design was employed. The population consisted of all tenth-grade students at SMA Negeri 1 Singaparna, and the sample was selected through cluster random sampling from class X-3. The instrument was a mathematical literacy essay test, validated by experts and tested for validity and reliability on a separate sample. Data were analyzed using descriptive statistics and N-Gain calculations with IBM SPSS Statistics 24, including the Shapiro–Wilk normality test and a one-sample t-test. The findings revealed a mean N-Gain score of 0.66 (moderate category), indicating the model’s effectiveness in improving students’ mathematical literacy. Moreover, students’ literacy levels after the intervention also fell into the moderate category. Practically, this study provides teachers with learning resources, such as teaching modules, to support instruction and foster collaborative, discovery-based learning that deepens students’ understanding of mathematical concepts.

Abstract

Mathematical disposition, which encompasses students’ confidence, perseverance, curiosity, and appreciation toward mathematics, plays a significant role in shaping their approaches to problem-solving. This study aims to investigate gender-based differences in students’ mathematical disposition and problem-solving ability, and to analyze the overall relationship between these variables. A quantitative approach employing a comparative–correlational design was used. Following Yount’s sampling guideline, 10% of the population (comprising 39 seventh-grade students) was randomly selected through simple random sampling. Research instruments included a Likert-scale questionnaire to measure mathematical disposition and an essay-based test developed from the IDEAL problem-solving framework. Both instruments were previously validated and tested for reliability to ensure data accuracy. Data were analyzed using an independent-samples t-test and Spearman’s rank correlation. Results revealed no significant difference in mathematical disposition between male (M = 67.26) and female students (M = 65.65), t(37) = 0.553, p > 0.05. In contrast, a significant difference was found in problem-solving ability, with male students (M = 69.42) outperforming females (M = 56.70), t(37) = 2.77, p < 0.05. Moreover, a low positive correlation (ρ = 0.2172) was observed between mathematical disposition and problem-solving ability. These findings suggest that gender factors may influence students’ cognitive and affective engagement in mathematical problem-solving. The study contributes to the growing body of research on mathematics education by emphasizing the importance of integrating affective and cognitive dimensions in designing more personalized and effective teaching practices

Abstract

This study investigates the feasibility and practicality of developing the Play Mathematics media using Articulate Storyline 3, designed to help eighth-grade students at SMP Negeri 6 Tasikmalaya explore their understanding of algebraic concepts. This R&D research employed the ADDIE model and involved media and content validation, as well as the measurement of student responses and conceptual understanding. The findings indicate that the media is highly feasible, with a technical feasibility score of 93% and a content and objective feasibility score of 92%, and is considered highly practical based on student evaluations. Additionally, the majority of students achieved very good and good levels of conceptual understanding. In conclusion, the Articulate Storyline 3-based Play Mathematics media is a feasible, practical, and effective tool for mathematics learning, particularly in exploring mathematical concepts.
