Abstract

Mathematics plays an important role in daily life, but students often have trouble solving word problems, especially on the topic of direct proportion. This difficulty highlights the need for a profile of students' problem-solving processes to help teachers identify where learning challenges occur. This study aims to describe the problem-solving profile for direct proportion based on the logical-mathematical intelligence of eighth-grade students at SMPN 19 Palu. The research used a descriptive qualitative approach. The subjects of the study were two eighth-grade students chosen based on the results of logical-mathematical intelligence questionnaire, each representing the high (AST) and low (PTR) categories. Data was collected through written tests and in-depth interviews, then analyzed using techniques of data condensation, data presentation, and drawing conclusions. The research results show that AST was able to complete all four stages of Polya completely and accurately with the correct answer (12 liters), while PTR only managed to understand the problem stage and made fundamental conceptual mistakes in the next stages (wrong answer: 5.333 liters). PTR also couldn't verify the answer. It was concluded that mathematical logical intelligence has a decisive influence on the quality of solving ratio problems at each stage of Polya.

Abstract

Exponential functions pose conceptual challenges for secondary students due to their abstract nature. This quasi-experimental study investigated the effect of GeoGebra-based instruction on Grade 10 students’ conceptual understanding in two Indonesian senior high schools (N = 132). A validated four-item essay test (r > 0.219; Cronbach’s Alpha = 0.71) was administered before and after instruction. Mann–Whitney U analysis showed a significant difference in posttest conceptual understanding between the GeoGebra and conventional groups (p < .001), with a moderate-to-large effect size (r = 0.44). These results provide classroom-based empirical evidence that dynamic visualization through GeoGebra strengthens students’ conceptual understanding and supports its structured integration in conceptually demanding mathematics topics.

Abstract

This study aims to describe the problem-solving process for composition and inverse functions using Polya's stages, based on the mathematical abilities of students at SMA Negeri 1 Pamona Utara. The results show differences in problem-solving approaches according to students' mathematical proficiency. (1) Students with high mathematical ability can accurately identify given and required information, assess the sufficiency of the available data, and understand the relationships between different pieces of information. They can also determine additional necessary information, utilize all essential data, and systematically plan their problem-solving process. Moreover, they are skilled in answering accurately and verifying their solutions by identifying errors. (2) Students with moderate mathematical ability exhibit similar skills in understanding problems and planning solutions. However, in inverse function problems, they struggle to apply systematic steps and are less precise in their answers. (3) Students with low mathematical ability can identify given information and its connections but are unable to develop an effective problem-solving strategy. They still face difficulties in structuring systematic steps to arrive at the correct solution.
