Abstract

This study aims to 1) evaluate students' mathematical representation skills before participating in HOTS practice questions, 2) evaluate students' mathematical representation skills after participating in HOTS practice questions, and 3) determine the improvement in students' mathematical representation skills through HOTS practice questions. This research uses a quantitative method with a one-group pretest-posttest design. The research population included 60 fifth-grade students from SD Negeri 1 Pelandakan, Cirebon, with a sample of 30 students selected using purposive sampling. The instrument used was a mathematical representation skills test. Data were analyzed using the N-Gain test and paired sample t-test to compare pretest and posttest results. The study results show that: 1) the average mathematical representation skills of students before participating in HOTS practice questions was 67.83, classified as weak category; 2) the average mathematical representation skills of students after participating in HOTS practice questions was 85.38, clasified as strong category; and 3) there was a significant improvement in students' mathematical representation skills, with an average N-Gain score of 0.5551 and p < 0.000. This improvement falls under the moderate category and is statistically significant. These findings suggest that HOTS-based practice questions effectively enhance mathematical understanding and should inform curriculum and instructional planning.

Abstract

This study addresses persistent difficulties in students’ geometry problem-solving, particularly in coordinating representations and applying structured reasoning. Prior research has shown the potential of problem-based learning (PBL) and digital tools; however, limited evidence exists regarding how technology-enhanced PBL supports students’ engagement across Polya’s problem-solving stages. To examine this issue, a quasi-experimental pretest–posttest control group design was employed involving two intact undergraduate geometry classes. The experimental group was taught using e-Problem-Based Learning (e-PBL), while the control group received conventional instruction. Students’ performance was measured using a Polya-based problem-solving test. Data were analyzed using descriptive statistics, assumption testing, and an independent samples t-test. The results showed that the experimental group outperformed the control group (M = 70.74 vs. 65.07), with a statistically significant difference (p < .001) and a large effect size (d = 1.16). Performance gains were observed across all four stages of Polya’s framework, particularly in the planning and reflection stages. These findings suggest that e-PBL is associated with improved mathematical problem-solving performance by supporting structured reasoning and reflective thinking. The research emphasizes the necessity of integrating digital scaffolding and collaborative inquiry in geometry instruction.

Abstract

This quantitative experimental study aims to examine the effect of mathematical representation ability and mathematical spatial ability on students’ mathematics learning outcomes, with gender as a moderating factor. The population consisted of 74 third-semester Mathematics Education students at UIN Syekh Nurjati Cirebon during the 2024/2025 academic year. A sample of 30 students was selected using purposive sampling. Validated test instruments were used to measure mathematical representation ability, spatial ability, and learning outcomes. Data were analyzed using simple and multiple linear regression. The results show that for female students, both abilities significantly and positively influenced learning outcomes (p < 0.05). For male students, only mathematical spatial ability showed a significant effect (p < 0.05). These findings suggest that female students may be better at integrating representational and spatial skills in mathematical learning than their male counterparts
