Abstract

This study aims to analyze the critical thinking skills of grade 2 students of Kedungmutih Elementary School in measurement material using non-standard units through the Indonesian Realistic Mathematics Education (PMRI) approach. This research used a qualitative method with a descriptive approach. The research subjects were grade 2 students, and data collection was done through observation, interviews, tests, and documentation. The results showed that the PMRI approach and the use of nonstandard measuring tools such as the “Who is More” game helped improve students' critical thinking skills. Students are better able to observe, compare, and draw logical conclusions from the measurement activities carried out. Although some students still have difficulties in understanding the concept of instability of nonstandard unit measures, this study shows that learning with the PMRI approach creates a more interactive and meaningful learning atmosphere, which is relevant to everyday life.

Abstract

This study was motivated by the low collaboration skills of students, which were reflected in the lack of active participation in discussions, lack of responsibility in group assignments, and the tendency to discuss outside the learning topic. This study aims to analyze the impact of the implementation of the Project-Based Learning (PjBL) model on the collaboration skills of class VII students at SMP Negeri 7 Kotabumi. The study used a quasi-experimental method with a Nonequivalent Control Group Design. The research sample consisted of class VIIA as the experimental group and VIID as the control group, each with 35 students. Data were collected through questionnaires and authentic assessment observations. Data analysis was carried out using parametric statistical tests. The results of the study indicate that the Project-Based Learning (PjBL) model has a significant impact on students' collaboration skills. Hypothesis testing at a significance level of 0.05 produces a tcount value = 2.31> ttable = 1.995, so the null hypothesis is rejected. This indicates that the implementation of Project-Based Learning (PjBL) has a positive impact on collaboration skills. Conclusion, the Project-Based Learning (PjBL) model has a positive impact on students' collaboration skills and can be an alternative innovative learning to face the challenges of 21st century education.

Abstract

This research was motivated by observations at SMP Negeri 7 Bukittinggi. The observation results show that there are still many VII grade students who have low mathematical reflective thinking skills. One of the reasons for the low mathematical reflective thinking ability of students is because they are not accustomed to working on non-routine problems that contain indicators of mathematical reflective thinking ability. The purpose of this study was to describe the mathematical reflective thinking ability of students in class VII.2 SMP Negeri 7 Bukittinggi in the 2024/2025 academic year in solving mathematical problems. This type of research is descriptive quantitative used to provide a clear picture of the level of student ability in mathematical reflective thinking. The research subjects were students of class VII.2 who had been selected through purposive sampling technique and data collection using instruments in the form of mathematical problems solving tests designed to measure indicators of reflective thinking. The results showed that students' ability in mathematical reflective thinking was still concerning. Only 14.29% of students are in the sufficient category, 50% in the low category, and 35.71% in the very low category based on the results of the data analysis that has been done. The overall average of students in mathematical reflective thinking is 58.8%, which is included in the low category. This shows that most students have difficulty identifying what is known and asked in the problem (reacting), comparing and connecting old problems with new problems (comparing/elaborating), and reflecting and re-evaluating their answers before drawing conclusions (contemplating).
