This research was done to know student learning outcomes in junior high schools using the SAVI (Somatic, Auditory, Visual, Intellectual) learning model in the PMR (Realistic Mathematical Education Approach) setting. This study used a quasi-experimental method (Quasi-Experimental Design). In contrast, the sampling technique used was random cluster sampling using two classes, one as the experimental group class and one as the control group class. Data analysis techniques are normality tests, homogeneity tests, and hypothesis testing. Based on the study's results, it was found that there was an increase in student learning outcomes. The scores of student test results indicate this. Of 24 students who did not pass, only 2 people (5%) and 22 people (95%) passed. So that the results of the study concluded that the average student learning outcomes taught exceeded the minimum completeness criteria set by the school

This study sought to examine and evaluate the average learning outcomes of students who received instruction in a system of two-variable linear equations using either the direct learning model or the blended learning model. The research employed the posttest-only control design. The participants in this study comprised of two groups: class VIII-A, an Experimental class consisting of 17 students, and class VIII-B, a control class consisting of 17 students at SMP Negeri 4 Touluaan. The data collected pertains to the posttest outcomes in both the Experiment and Control groups, indicating an average learning outcome of 85.29 for the Experiment group and 77.94 for the Control group. The normality test for the data is satisfied when the data follows a normal distribution. The study yielded results indicating a significant level of 0.05, with the obtained t-value of 1.89098 being greater than the critical t-value of 1.694. According to the findings of this study, students who engage in Blended Learning exhibit superior learning outcomes in the context of acquiring proficiency in solving systems of linear equations with two variables, as compared to students who rely solely on direct instruction.

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.

This research aims to determine the utilization of information technology in mathematics learning in Class VIII of SMP Negeri 1 Parigi Selatan. This is a case study that describes an actual situation. In collecting data, the researcher used data collection procedures through interviews with informants, who, in this case, were students, as the source of data and information. Qualitative data analysis in this research uses the SWOT analysis method, which systematically identifies various factors to formulate company strategies. This analysis is based on the logic that can maximize strengths and opportunities while minimizing weaknesses and threats. Then, identify the types of errors and conclude. From the strengths perspective, the results indicate that implementing online learning allows learning resources to be easily accessed online. From the perspective of weaknesses, an unstable internet connection affects students' focus on learning and teaching. From the perspective of opportunities, online learning enhances students' self-learning skills and provides new insights into technology and learning. Finally, from the perspective of threats, students' learning motivation decreases.
