Abstract

Numerous studies have demonstrated that the implementation of problem-based learning (PBL) can enhance student motivation and learning outcomes. However, the integration of contextual media in these instructional activities remains limited. This research aims to investigate the impact of using PBL with contextual media on student outcomes, compare the differences in mathematics achievement between students taught through PBL with contextual media and those taught through conventional methods, and assess variations in student motivation between these two instructional approaches. A quasi-experimental design with a non-equivalent pretest-posttest control group was employed in this study. The participants consisted of 60 sixth-grade students, divided into an experimental group (taught using PBL with contextual media) and a control group (taught using conventional methods). Data were collected through learning motivation questionnaires and objective mathematics tests, with data analysis conducted using normalized gain scores (N-Gain) and t-tests. The results indicated significant improvements in student outcomes when taught using PBL with contextual media. Additionally, there was a marked difference in mathematics achievement between the experimental and control groups, as well as differences in student motivation between the two instructional methods. These findings suggest that implementing PBL with contextual media presents a promising strategy for enhancing both student motivation and mathematics learning outcomes.

Abstract

The purpose of this study was to determine the ability to solve problems and think critically through problem-based learning. The problem-based learning framework supports talent abilities by shaping students' thinking. This study involved students of class VIII-A SMP PGRI 4 Medan. The research approach used descriptive qualitative. SMP PGRI 4 Medan became the locus of the 2024/2025 research. This study used interviews and assessments of problem solving and critical thinking. The results showed that students' mathematical problem solving abilities averaged 65, which was moderate. Students' critical thinking averaged 66.9, which was moderate. The difficulties faced by students by comparing the results of the interview can be seen that students have difficulties in the four indicators of problem solving and critical thinking abilities. Where students ignore or do not recheck or draw conclusions and only concentrate on the solution procedure. This study shows that students have moderate problem solving and critical thinking skills when dealing with a system of linear equations of two variables.

Abstract

The purpose of this study was to analyze and describe the use of deductive reasoning and mathematical problem solving skills based on Adversity Quotient (AQ). The type of research used is qualitative descriptive research. The instruments in this study were deductive reasoning and problem solving ability test questions, and AQ questionnaires. The number of respondents in the study was 20 students. Respondents were divided into three types, namely Quitter, Camper, and Climber. The results showed that students with the Quitter type were only able to make calculations based on rules/formulas, but had not been able to draw conclusions and compile direct proof steps so that the problem solving indicators had not been achieved optimally. Students with the Camper type were able to make calculations based on rules or formulas, and were able to plan and implement plans in the problem solving aspect. Students with the Climber type were able to meet all indicators of deductive reasoning and problem solving in understanding problems, planning, implementing plans, and re-checking

Abstract

The Implementation of Content Differentiated Learning Based on Students' Readiness in the Topic of Presenting Data in the Form of a Scatter Plot in Class XI-7 of SMA Negeri 1 Jayapura. This research is a descriptive qualitative study aimed at describing the implementation of content differentiated learning based on students’ readiness in the topic of presenting data in the form of a scatter plot. The subjects of this study were 37 students from Class XI-7 of SMA Negeri 1 Jayapura, selected through purposive sampling technique.. The research instruments used included a teaching module, diagnostic assessment, individual test, and teacher observation sheet. The results of the diagnostic assessment were used to categorize students into three levels of readiness: low, medium, and high. Students were grouped into seven groups: three low-readiness groups, three medium-readiness groups, and one high-readiness group. The differentiated learning was implemented effectively, as indicated by the teacher’s observation score of 86.875% and the peer observer’s score of 88.125%, both of which fall under the “very good” category. The results of the individual test showed that 27 out of 37 students (72,97%) met the KKM, while 12 students (27,03%) did not. Among the medium- readiness group, 5 students did not meet the criteria, and among the low-readiness group, 5 students were not yet successful. These findings indicate that content-differentiated learning positively impacts students' learning outcomes, although further support is needed for those in the low-readiness group.
