Abstract

The purpose of this study was to describe the errors made by students in solving story problems on pythagorean material in class VIII B SMP Negeri 2 Langowan based on Kastolan's theory. This research uses qualitative research, with the methods used in data collection are written tests in the form of description questions (essay), interviews, and documentation. The subjects in this study were class VIII Byang students totalling 29 students. Based on the results of the data obtained, it shows that in solving story problems on pythagorean material, students make mistakes at the stage of understanding the concept with a percentage of 15.17%, the stage of understanding the procedure with a percentage of 42% and the stage of understanding the technique with a percentage of 62%.

Abstract

This study aims to determine the difference in student learning outcomes using the Project Based Learning (PJBL) Model is higher than student learning outcomes using Direct Learning in mathematics learning curved side space building material. This type of research is Experimental Research using Posttes Only Control Group Design, this research was conducted at Rurukan Christian Junior High School. The subjects in this study were all students of class IX, where IX-A with 18 students as the experimental class and IX-B with 17 students as the control class, which were randomly selected. From the results of research and data analysis with a real level of 5% (0.05) shows the average value of the experimental class is 81.5 and the average control class is 74.23. Thus it can be seen that student learning outcomes using Project Based Learning (PJBL) are higher in learning mathematics curved side space building material

Abstract

The objective of this study was to assess the impact of the Open Ended approach on the mathematics learning outcomes of seventh-grade students at SMP Negeri 1 Lembo, specifically regarding Triangle Material. This research is classified as pseudo-experimental, utilizing a quantitative approach and employing a Non-equivalent Control Group Design. Class VII B served as the experimental class with 20 students, while class VII C acted as the control class, also comprising 20 students. The data collected for this study were analyzed using Microsoft Excel with a t-test, revealing a tcount value of 3.39484, which is greater than the ttable value of 2.02439 at a significance level of α = 0.05. Consequently, the research hypothesis was accepted. The findings of this study indicate that the Open Ended approach significantly influences the learning outcomes of seventh-grade students at SMP Negeri 1 Lembo in relation to triangle material.

Abstract

The aim of this study was to assess students' understanding of mathematical concepts pertaining to triangle topics. This research employed a qualitative approach, intending to generate descriptive data through written and verbal expressions from various sources observed. The study took place at SMP Negeri 1 Tenga, located in South Minahasa. Data collection methods comprised written tests and interviews, which were administered to a total of 12 eighth-grade students. The gathered data was analyzed by categorizing students into three groups based on their understanding of mathematical concepts. Findings revealed that 83.3% of the eighth-grade students at SMP Negeri 1 Tenga achieved a high level of understanding at the translation stage, as this indicator was relatively straightforward. In contrast, 66.6% demonstrated a good understanding at the interpolation stage, as some students were able to effectively select and apply appropriate procedures. However, only 33.3% of students exhibited comprehension at the extrapolation level, which fell into the low category, primarily due to difficulties in problem-solving accuracy and an insufficient grasp of the problems. Additionally, the distribution of understanding levels included 3 students in the high category, 3 in the medium category, and 6 who displayed a very low understanding of mathematical concepts at both the extrapolation and interpolation levels, as well as at the translation level

Abstract

This research aims to design and develop a learning device in the form of ethnomathematics-based LKPD containing questions and explanations related to local culture that are valid, practical, and effective. The type of research used is Research and Development (R&D) employing the ADDIE model, which consists of the stages of Analysis, Design, Development, Implementation, and Evaluation. The percentage of assessment results obtained from media validators was 92.72%, and the percentage of assessment results from material validators was 96.66%, categorizing them as very valid. Based on the percentage of student responses to the ethnomathematics-based LKPD on the topic of surface area and volume of a cylinder, an average percentage of 91.99% was obtained, categorized as very practical. Furthermore, according to the effectiveness aspect, a student mastery percentage of 85% was obtained, categorized as very effective. Thus, the conclusion of this study is that the development of learning devices, in this case, ethnomathematics-based LKPD on the surface area and volume of cylinders, meets the aspects of validity, practicality, and effectiveness
