Abstract

This type of research is development research using R&D (Research and Development) with the Plomp development model consisting of three stages, namely Preliminary research, prototyping phase, assessment phase but in this study it only reached the prototyping phase. The instruments used are validity, practicality and independence questionnaires. The result of the validity of the validator is 88.57% with very valid criteria. The results of the practicality of learning worksheets with one mathematics teacher and students obtained a score of 97.4% in the very practical category. The learning outcomes of students using LKPD 6 students obtained a value of 93.40% with very valid criteria. Based on the results of this study, it can be concluded that learning media using Project Based Learning (PjBL) Based Learning Worksheets on Quadrilaterals and Triangles Material are valid and practical, and Project Based Learning (PjBL) Based Worksheets make students independent in the learning process on quadrilaterals and triangles material .

Abstract

This research was motivated by the test instrument used by teachers at SMP Negeri 7 Padang. The limitations of the test questions used by the teacher emphasize the mastery of basic skills and there is no application of mathematics in everyday life.This study aims to produce a problem solving test instrument that is valid and reliable. This type of research is research and development (R&D) using the Plomp model. The Plomp model consists of 3 phases, namely Preliminary Research, Prototyping Phase and Assessment Phase. The instruments used were interview guidelines and validity sheets. The test subjects in this study were class VIII students of SMP Negeri 7 Padang with a total of 26 students. Where 3 students as one to one test subjects and 23 students as small group test subjects. The results of this study indicate that the student problem solving test instrument is very valid, namely 88.33%. In the reliability analysis the instrument has a high reliable value of 0.72 and the reliability value is in the range of 0.60 < < 80

Abstract

The role of mathematics needs serious attention, considering its benefits in everyday life. Mathematics lessons are provided starting from elementary school to tertiary institutions in order to equip students to have the ability to think logically, critically, and creatively. The low ability to understand students' mathematical concepts is due to the fact that previously, students carried out online learning, so the teaching carried out was not adequate, and many students did not do the assignments given, resulting in students not understanding mathematical concepts correctly. The purpose of this study was to describe the ability to understand mathematical concepts of class VIII.1 students of SMP Negeri 2 Tanjung Raya. The subjects of this research were class VIII.1 students of SMP Negeri 2 Tanjung Raya. The research method used is a descriptive method with a qualitative approach. The sampling technique used purposive sampling. Instruments are used to collect data in the form of tests of ability to understand the concept, interviews, and documentation. The test results were analyzed based on indicators of understanding the concept. The results of the research on academic ability related to the ability to understand concepts are high, medium, and low from the test results.

Abstract

This study investigates the effect of the Realistic Mathematics Education (RME) model on students’ conceptual understanding in mathematics within the framework of the Merdeka Curriculum. Despite curriculum reforms emphasizing student-centered learning, many classrooms remain teacher-centered, resulting in low levels of student engagement and poor conceptual understanding. This quasi-experimental study employed a one-group pretest-posttest design with a quantitative approach. The research involved students from class VIII.6 at MTsN 2 Pesisir Selatan, selected through purposive sampling. A total of four essay-type items were used in both pretest and posttest assessments, targeting three key indicators of conceptual understanding: restating concepts, applying problem-solving algorithms, and representing mathematical ideas in various forms. Data analysis involved normality and homogeneity tests, followed by a paired sample t-test to determine statistical significance. The results showed that students’ posttest scores improved significantly compared to their pretest scores, with a t-value of 18.63 exceeding the critical value at a 5% significance level. Qualitative analysis further supported the quantitative findings, as students demonstrated notable improvement across all indicators. These results suggest that the RME model effectively enhances students' conceptual understanding by fostering contextual learning, active participation, and collaborative problem-solving. The study concludes that RME is a promising instructional model that aligns well with the goals of the Merdeka Curriculum and recommends its broader implementation in mathematics education to improve learning outcomes.
