Abstract

The integration of problem posing and problem-solving learning facilitates problem situations that require students to actively engage in tackling non-routine mathematical challenges. However, some students are still not well-adapted to this type of problem-solving, making it potentially less effective when applied simultaneously. This study aims to analyze students’ mathematical problem-solving abilities through problem-posing and problem-solving learning assisted by Heyzine. This research employed a quasi-experimental method. The population consisted of eleventh-grade students from a senior high school in Bandung Regency, with classes XI D1, XI D2, and XI E1, each comprising 37 students selected through random sampling. The findings of this study include: (a) the design of the Jucama learning model was successfully implemented, resulting in a Heyzine-assisted student worksheet (LKPD) that met the criteria of being highly valid and suitable for use; (b) the implementation process of the Jucama learning activities assisted by Heyzine improved significantly and achieved a very good category; (c) there was a notable increase in problem-solving ability among students who received Heyzine-assisted Jucama learning compared to those who received Jucama learning without Heyzine.

Abstract

The purpose of this study was to determine whether or not there was an influence of the realistic mathematics approach on students' ability to understand mathematical concepts. This study used a systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Research articles were found from the publication years 2015–2022, and they were indexed by Google Scholar. Grouping, data analysis, and drawing conclusions were the analysis techniques used. After that, the results were as follows: there was an influence of the realistic mathematics approach on students' ability to understand mathematical concepts; the presence or absence of technology in the application of the realistic mathematics approach can both improve students' ability to understand mathematical concepts; and many studies on the influence of the realistic mathematics approach on students' ability to understand mathematical concepts can be evaluated by considering the year of publication, level of education, sample size of the experimental class, status of assistance and combination of learning.
