Abstract

Abstract: Problem-solving in mathematics is a fundamental skill that must be mastered by individuals. However, previous research indicates that students' problem-solving abilities tend to be moderate to low. Many factors contribute to this, including the factor of number sense ability. The objective of this study is to describe how number sense and problem-solving skills are used by mathematics education students with low number sense ability in solving linear programming problems using the simplex method. This research is qualitative descriptive involving 36 third-year mathematics education students as participants. Subjects were selected using purposive sampling technique based on a number sense ability test to identify those with low number sense ability. Participants were given an advanced test involving linear programming problems solved using the simplex method. The results indicate that mathematics education students with low number sense ability struggle to solve problems accurately. Stages of problem-solving that were not performed effectively included gathering information, planning, and implementing the plan. Furthermore, students did not engage in the reviewing stage. Moreover, students were not flexible in manipulating numbers, especially when dealing with large numbers. As a result, more time was required for computations, and the iteration process in the simplex method could not be effectively completed.        Keywords: linear programming, number sense, number sense ability, problem solving, simplex method.DOI: https://dx.doi.org/10.23960/jpmipa/v25i1.pp103-115

Abstract

This study aims to systematically review the literature on the influence of the integration of Problem-Based Learning (PBL) with digital technology on the mathematical critical thinking skills of secondary school students. The method used is Systematic Literature Review (SLR) by examining primary studies obtained from Google Scholar, Scopus, and Web of Science published between 2020-2024. Articles were analyzed based on the year of publication, level of study, teaching materials, research methods, and research results. The results of the study show that the application of PBL based on digital technology is effective in improving students' critical thinking skills. The use of electronic LKPDs, digital pocketbooks, interactive e-modules, animated videos, and Classwiz emulators has been proven to support an active, collaborative, and meaningful learning process. The integration of digital technology in PBL not only increases the effectiveness of material delivery but also strengthens the internalization of concepts through learning experiences relevant to 21st century skills. This study concludes that PBL integrated with digital technology has a positive influence in improving the mathematical critical thinking skills of high school students.
