Abstract

The COVID-19 pandemic has had an impact on the learning process in schools. For this reason, researchers observed learning at SMA Negeri 1 Gorontalo, it was found that students were still not optimal in solving mathematical problems, especially in formulating steps to solve problems. This research aims to improve students' problem-solving abilities by using GeoGebra on three-dimensional material. The research was carried out at SMA Negeri 1 Gorontalo in class XII IPA 5 from September to October of the 2022/2023 academic year with research subjects totaling 30 students. The research is Classroom Action Research (CAR) using the Kemmis and McTaggart model, which involves the stages of planning, action, observation, and reflection. Data was obtained from observation and written tests. Analysis of observation results was obtained by calculating scores for each aspect criterion observed both on the teacher observation sheet and the student observation sheet, while the written test was analyzed by referring to the minimum completeness criteria. The results of the research show that there is an increase in students' problem-solving abilities in three-dimensional material after taking action using the GeoGebra learning media.

Abstract

Relational understanding is an essential skill that reflects students' mastery of the relationships between mathematical concepts, while APOS Theory provides a framework for analyzing the mental construction of this understanding. This study aims to identify and compare the application of APOS Theory and relational understanding in the context of mathematics learning. This study used the Systematic Literature Review (SLR) method based on the PRISMA framework. The literature search was conducted in the Scopus and Google Scholar databases with publications limited to 2014 to 2024, focused on elementary and secondary school levels. Of the 228 identified studies, 11 empirical articles were selected for analysis. The review results showed significant differences in the focus of the material; APOS Theory is predominantly applied to number topics and is often used as a basis for developing assessment instruments. In contrast, relational understanding is more widely studied in algebra topics. Furthermore, it was found that the problem-solving approach is a major factor influencing the formation of students' relational understanding. These findings offer educators insights into selecting pedagogical approaches that are suitable for the material's characteristics.
