Abstract

Low levels of student engagement and learning motivation have led to limited critical thinking skills, which in turn have affected students’ learning outcomes that remain below the Minimum Mastery Criteria (MMC). This study aims to determine whether students who received instruction through the Problem-Based Learning (PBL) model achieved higher mathematics learning outcomes than those taught using the conventional (lecture-based) model on the topic of Relations and Functions. This research employed a quasi-experimental method with a pretest–posttest control group design. Population consisted of eighth-grade students from SMP Negeri 3 Tondano, while the samples were class VIII-A (22 students) as the experimental group and class VIII-B (17 students) as the control group. The research instrument comprised written essay tests administered as pretests and posttests in both groups. Data were analyzed using inferential statistical procedures. Data were first tested for normality using the Liliefors test, followed by a homogeneity test (F-test). After both assumptions were met, an independent samples t-test (two-tailed) was performed to test the hypothesis. The results showed a statistically significant difference in mathematics learning outcomes between students who learned through the PBL model and those taught using the conventional lecture-based method. Therefore, it can be concluded that the implementation of the PBL model effectively enhances students’ mathematics learning outcomes on the topic of Relations and Functions, providing evidence that active, problem-oriented instruction can improve students’ conceptual understanding and achievement in mathematics.

Abstract

Students' problem-solving abilities in solving mathematics story problems could be much higher. Innovation and special studies are needed regarding learning models that can improve problem-solving abilities. This research aims to determine the differences in the test results of students' mathematical problem-solving abilities in solving story problems taught using the think pair share type cooperative learning model with the problem-based learning approach and the results of tests of students' mathematical problem-solving abilities taught using the conventional model on cube and block material. The subjects of this research are class VIIIA, which is taught using a think pair share type cooperative learning model with a problem-based learning approach, and class VIIIB, which uses a conventional learning model. The two classes are homogeneous or equal. The data in this study were taken from the pre-test and post-test results from both classes. Thus, the test results of students' ability to solve mathematical problems to solve story problems are better using the think pair share type cooperative learning model with a problem-based learning approach than the conventional learning model using cube and block material.

Abstract

This study tries to identify the faults and circumstances that lead students to miscalculate when attempting to solve word problems involving a system of linear equations with two variables using Watson's criteria. This kind of study employs qualitative, descriptive research methods. Data was gathered using a variety of methods, including analysis, interviews, documentation, and a written test with five-item description questions. Class VIII students from SMP Negeri 5 Tondano 2022/2023 served as the study's sources and subjects. They were chosen after careful consideration. Data analysis techniques in this study through data reduction, data presentation, and conclusions. The results showed that the students' errors were incorrect data, inappropriate procedures, response level conflicts, and skills hierarchy problems. The causative factors are that students are not careful when writing answers, students think that conclusions do not need to be written down, students forget how to change the story form questions into the form of mathematical models or the principles used are still wrong, students forget to write examples, students are wrong in operating numbers either subtraction, addition, division and multiplication, students forgot to write conclusions, students were unable to write down existing data, students did not know how to answer questions, students forgot to find x and y values using the substitution method, students used wrong marks in mathematics, students ran out of time when solving problems.

Abstract

This study aims to determine whether there is an effect of applying the Snowball Throwing cooperative learning model on mathematics learning outcomes in grade VII on the subject of Algebraic Operations at SMP Negeri 2 Tondano using quantitative research through an experimental method with two classes randomly selected as subjects. The research instrument was a post-test consisting of multiple-choice and essay questions that had been tested for validity and reliability. From the hypothesis testing using the t-test, tcount = 5.567 > ttable = 2.023, which means rejecting Ho. Therefore, it can be concluded that the average learning outcomes of students on the subject of algebraic operations using the Snowball Throwing model are higher than the average learning outcomes of students using the conventional learning model.

Abstract

This study aims to analyze the influence of teacher performance and school environment on elementary school students’ learning outcomes in Cluster 1, Tikala District,Manado City. The research employed aquantitative approach using a survey method to obtain empirical data regarding the relationships among the variables studied. The research subjects were elementary school teachers in Cluster 1, Tikala District, Manado City, selected using proportional sampling to ensure that each school had a proportional opportunity to be included in the sample. Data were collected through questionnaires as research instruments, which had previously undergone validity and reliability testing to ensure their appropriateness. The collected data were analyzed using multiple linear regression analysis with the assistance of SPSS as a statistical analysis tool. The results indicate that teacher performance has a significant effect on students’ learning outcomes, and the school environment also significantly influences students’ learning outcomes. Simultaneously, teacher performance and school environment contribute significantly to improving students’ learning outcomes. These findings suggest that the improvement of students’ learning outcomes is influenced not only by teachers’ professionalism in implementing the learning process but also by the creation of a conducive, safe, and supportive school environment that enhances the effectiveness of teaching and learning activities.

Abstract

Purpose: This study aims to systematically review the mathematical concepts represented in Hill Cipher-based cryptography and examine their applications and implications for mathematics education across different educational levels. Methods: A systematic literature review was conducted following the PRISMA 2020 guidelines. Literature searches were performed across five academic databases, yielding 1,247 initial records. Following identification, screening, eligibility assessment, and quality appraisal, 14 primary studies published between 2020 and 2023 were included for qualitative thematic synthesis. Findings: The review identified modular arithmetic, matrix multiplication, and matrix inversion as the predominant mathematical concepts represented in the reviewed studies. Modular arithmetic appeared in all 14 studies and was primarily associated with secondary-level mathematics, whereas matrix operations were predominantly implemented in undergraduate contexts. The reviewed studies reported educational applications including mathematics learning media, simulation-based learning, and project-based learning. However, only a limited number of studies explicitly investigated classroom implementation, while most focused on algorithmic development and technical applications. In addition, the available evidence was dominated by studies conducted in Indonesia, limiting the broader generalizability of the findings. Research Implications: This review provides a conceptual synthesis that connects mathematical concepts, classical cryptographic algorithms, and their potential educational applications. The findings may inform mathematics educators, teacher educators, and curriculum developers in designing contextual mathematics learning activities while also highlighting the need for more classroom-based empirical studies across diverse educational settings. Originality: Unlike previous reviews emphasizing cryptographic performance and algorithm development, this study synthesizes the educational dimensions of Hill Cipher-based cryptography by mapping the relationships among mathematical concepts, instructional applications, and research gaps. The review contributes an evidence-based conceptual framework to support future research and curriculum development in mathematics education.
