Abstract

Population projections are scientific estimates based on assumptions about the factors that contribute to population growth rates, such as migration, births, and deaths. They are not population predictions. The future population's size and age distribution are determined by these three factors. Data describing trends from the past to the present are needed to make estimates about the pace of development of future births, deaths, and movements. The goal of this study is to use the logistic and exponential growth models to project the population growth in Sinonsayang Subdistrict. BPS Sinonsayang Subdistrict provided the population census data for Sinonsayang Subdistrict from 2016 to 2022. Both logistic and exponential models are used to model data analysis procedures. The model that was chosen was based on the findings.

Abstract

This research aims to examine the difference in improving mathematical problem solving abilities in the System of Linear Equations Two Variables material for students who applied the Problem Based Learning model and students who applied the Direct Instruction model. This research uses a quasi-experimental method, with a pretest-posttest control group design. The subjects in this research were 20 students in class VIIIA as the control class and 20 students in class VIIIB as the experimental class. Both classes are homogeneous and the same. Gain data analysis using the t-test concluded that there was a difference in the increase in the mathematical problem solving abilities of SPLDV material for students who applied the Problem Based Learning model and students who applied the Direct Instruction model. The results of the analysis of the level of students' mathematical problem solving abilities that apply the problem based learning model in the experimental class can be seen from the achievement of the KKM. Where 85% of students have been able to reach the KKM, while 15% of students are still below the KKM. This shows that the application of the problem based model has a better influence on increasing students' mathematical problem solving abilities

Abstract

Tujuan penelitian untuk mengetahui perbedaan. Hasil belajar siswa yang diajarkan dengan model Pendidikan Matematika Realistik Indonesia (PMRI) lebih dari hasil belajar model Pembelajaran Langsung (PL) materi Perbandingan. Penelitian ini menggunakan studi komparatif dengan, desain posttest only control group design, dan menggunakan metode quasi experiment. Subjek penelitian ini ada 18 siswa dikelas VIIA adalah kelas eksperimen dan 17 siswa dikelas VIIB adalah kelas kontrol. Pada kelas eksperimen diterapkan model PMRI, sedangkan, pada kelas kontrol diterapkan model PL. Hasil penelitian menunjukkan bahwa nilai rata-rata kelas eksperimen: 83,44, sedangkan, nilai rata-rata kelas kontrol: 74,76. Uji hipotesis menggunakan uji perbedaan rata-rata dua kelompok tidak berpasangan dengan taraf signifikasi 5%, hasil pengujian menyimpulkan bahwa hasil belajar siswa yang diajar dengan model PMRI, lebih baik dibandingkan dengan siswa yang diajar dengan model PL, pada materi Perbandingan

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 study aims to identify whether the learning outcomes of students who learn using the Problem Based Learning (PBL) model are higher than the learning outcomes of students who learn using the Conventional learning model on the material of Curved Side Spaces. This study used a posttest-only control group design. The population in this study were all grade IX students, with a sample consisting of grade IX A as an experimental class of 23 students and grade IX B as a control class of 23 students at SMP N 3 Tondano in the 2024/2025 school year. The results showed a difference in the learning outcomes of students taught with the Problem Based Learning (PBL) learning model compared to students taught with the Conventional learning model. Based on these results, it is concluded that learning using the Problem Based Learning (PBL) model can improve students' mathematics learning outcomes on the material of Curved Side Spaces.

Abstract

Mathematics trains one to think systematically, scientifically, critically, and creatively. Creative thinking such as Critical Thinking Skills, Creative Thinking Skills, Communication Skills, and Collaboration Skills are competencies needed in the second century. This research will be conducted in SMA Negeri 1 Kawangkoan Barat, Minahasa Regency, North Sulawesi Province. The subject selection technique in this study used a data source subject selection technique with certain considerations. Data were collected with questions that refer to 4 indicators and after the data were collected, descriptive quantitative analysis was conducted. The results obtained showed that the mathematical creative thinking ability of students at the SMA Negeri 1 Kwangkoan Barat level as a whole was in the moderately creative category with the results of indicators from highest to lowest, namely fluency 36%, flexibility 26%, originality 20%, elaboration 18%.
