Abstract

This study aims to determine the improvement of students' ability to understand mathematical concepts by using the Realistic Mathematics Approach (PMR). This study is a pseudo-experimental research with posttest only control group design. The population of this study is all students of grade XI SMK Negeri 6 Medan even semester of the 2025 school year with a total of 280 students and distributed into 8 classes. The sample of this study is class X Accounting 1 with a total of 36 students as an experimental class and class X Accounting 2 with a total of 35 students as a control class. Data were collected using tests and statistically analyzed to find out the differences between the two classes. The results of the hypothesis test with the Mann Whitney U test, it is known that the value of Z-count = 1.879 is more than Z-critical = 1.645. This shows that the median concept understanding of students who follow learning with the PMR Approach is higher than the median concept understanding that follows regular learning. The average value of students' concept understanding in the class applying the PMR approach x ̅=62 was higher than the class that followed the usual learning where x ̅=53. Thus, it can be concluded that the understanding of mathematical concepts of students who participate in learning with the PMR approach is higher than the understanding of mathematical concepts of students who follow ordinary learning

Abstract

This study aims to determine the effect of the Project Based Learning (PjBL) model on students' mathematical problem-solving abilities. This research uses a quantitative approach with a quasi-experimental method. The research sample consists of two eighth-grade classes at SMP Negeri 1 Pantai Cermin, each consisting of 30 students. Class VIII-1 serves as the experimental class treated with the PjBL model, while class VIII-2 serves as the control class using conventional methods. Data were collected through pretest and posttest, then analyzed using normality test, homogeneity test, and t-test. The test results indicate that the data is normally distributed and homogeneous. The t-test shows a significance value < 0.05, which means there is a significant difference between the two classes. The average posttest score of the experimental class (86) is higher than that of the control class (72). These results suggest that the PjBL model has a positive effect on improving students' problem-solving skills.

Abstract

This study aims to describe the implementation of assessment and evaluation of mathematics learning outcomes in spatial geometry material in the Merdeka Curriculum at SMA Negeri 1 Girsang Sipangan Bolon. The study used a descriptive qualitative approach with data collection through observation, interviews, and document analysis. The results of the study indicate that teachers have implemented formative assessment, practical assessment, and context-based assignments. However, authentic assessment has not been implemented consistently, and assessment instruments still tend to focus on students' procedural abilities, so that contextual abilities have not been optimally explored. The main obstacles in the implementation of assessment include limited learning time, the administrative burden on teachers, and teachers' skills in developing and using assessment rubrics. This study concludes that the implementation of assessment on spatial geometry material has been in line with the principles of the Merdeka Curriculum, but it still requires improvement in teacher competence and institutional support from the school so that assessment can be carried out more optimally.

Abstract

This study aims to analyse the problems and evaluate the implementation of the curriculum in mathematics learning at Deli Murni Bandar Baru Junior High School. The research used a qualitative descriptive approach with mathematics teachers and related parties at the school as the research subjects. Data were collected through in-depth interviews, observation of the learning process in the classroom, and analysis of curriculum documents and teaching tools, such as teaching modules and assessment instruments. The data obtained were analysed using qualitative analysis techniques through the stages of data reduction, data presentation, and conclusion drawing. The results showed that the implementation of the curriculum was quite good in terms of planning, as demonstrated by the teachers' ability to develop teaching tools in accordance with the curriculum requirements. However, the implementation of learning and evaluation was not yet optimal. Teachers still tended to use conventional learning methods and had difficulty in implementing authentic assessment. These findings emphasised the need to improve teacher competence through continuous training so that the implementation of the curriculum could be carried out more effectively and have an impact on improving the quality of mathematics learning

Abstract

This study aims to describe the implementation of Understanding by Design (UbD) as a framework for the Merdeka Curriculum at Santo Thomas 1 High School in Medan. This study uses a descriptive approach with a mixed qualitative and quantitative design. Research data were collected through interviews with teachers, observations of teaching and learning activities, analysis of teaching materials, and measurement of teachers' perceptions using a Likert scale questionnaire. Qualitative data were analysed through data reduction, data presentation, and conclusion drawing, while quantitative data were analysed descriptively to determine the categories of UbD implementation levels. The results showed that UbD implementation was in the good category, especially in the planning and formulation of learning outcomes stages. However, the learning implementation and assessment stages still needed improvement because they were not fully consistent with the backward design principle. Overall, UbD played an important role in strengthening the quality of learning planning in the Merdeka Curriculum, but further assistance was still needed to optimise its application in all stages of learning.
