<![CDATA[This study aims to identify errors made by students when solving mathematics problems, particularly in algebraic operations, and to analyze the factors contributing to these errors. Employing a qualitative descriptive method, the research involved 28 students. Data were collected through written tests and interviews. Interview results were used to determine the factors causing student errors in solving algebraic operation problems; written test results determined the percentage of each error type. The tests revealed that 57.14% of student errors were factual, 32.14% were conceptual, 25% were principle errors, and 64.28% were procedural.]]>

<![CDATA[Learning model that meets the criteria of being valid, practical and effective. This research is categorized as development research. This study uses the ADDIE model developed by Dick and Carey. There are five stages, namely: 1) Analysis, 2) Design, 3) Development, 4) Implementation, and 5) Evaluation. The learning tools produced in the study were the lesson plan (RPP), student activity sheets (LKPD) and evaluation of learning outcomes (EHB). The results showed that the products developed to meet the criteria of validity, practicality, and effectiveness. The learning device is feasible to use with an average score of the learning device assessment from the validate of 3.5 with valid criteria. The practicality of the learning device was seen from the student response questionnaire which gave a positive response and the teacher's ability to manage learning at the first meeting with an average of 3.69 and the second meeting of 3.46 which reached the good category, which was located in the interval 3.50 ≤ TKG < 4 , 50. The effectiveness of the learning device is seen from the test of student learning outcomes which shows the value of student learning completeness by an average of 80%.]]>

<![CDATA[This study aims to determine the differences in student learning outcomes taught with the Problem Based Learning model and student learning outcomes taught with the Direct Instruction model on social arithmetic material. This study used a quasi-experimental method, with a research design of Posttest Only Control Group Design. The samples of this study were taken from 2 homogeneous and the same classes, class VIIA which consisted of 20 students as the experimental class and VIIB which consisted of 20 students as the control class. Research statistics were analyzed using t-test with tcount = 3.644 ttable value = 1.686 then H0 was rejected. Thus, it is concluded that the average learning outcomes of students who are taught using the Problem Based Learning (PBL) model are higher than the average learning outcomes of students who are taught using the Direct Instruction (DI) model on social arithmetic material.Keywords : Problem Based Learning Model, Sosial Arithmetic, Learning Outcomes]]>

<![CDATA[The purpose of this study is to examine how students make mistakes when attempting to solve equality and inequality problems in trigonometry and algebra using the Newman method. A qualitative descriptive research methodology is employed in this study. Students enrolled in Manado State University's 2023–2024 Mathematics Education Study Program during their first semester served as the research subjects. Test and interview techniques are used in data collection. Three steps made up the data analysis in this study: reduction, data display, and data verification. Data analysis utilizing the Newman approach yielded the following conclusions: 5.6% encoding errors, 4.8% reading errors, 12% comprehension errors, 8.4% transformation errors, and 18.8% process skill errors were made when solving equation and inequality problems. The inability of pupils to comprehend the concept of the subject being explained, their lack of willingness to study, and their carelessness when reading and completing questions are the causes contributing to these blunders.]]>

<![CDATA[In learning mathematics, students' ability to solve problems affects their learning outcomes. At Smp Negeri 1 Kakas in class VIII, it was found that students' mathematics learning outcomes were still low, especially in the material of the system of linear equations of two variables, this was due to the lack of students' ability to solve mathematical problems. Therefore, the Missouri Mathematics Project model is applied in learning to solve one of the factors causing the above problems. This study aims to see student learning outcomes in learning mathematics material on the system of linear equations of two variables by knowing the average difference in learning outcomes of students who learn using the Missouri Mathematics Project learning model and those who learn using the direct learning model. This research is an experimental research that uses a quantitative approach. The samples in this study were class VIII-D as the experimental class and class VIII-A as the control class at Smp Negeri 1 Kakas in the 2023/2024 academic year. The instrument in this study was an essay-shaped student learning outcomes test. Data collection techniques through posttest results on the material of the system of linear equations of two variables in the experimental class and control class. The results of this study were obtained based on hypothesis testing using t-test statistics obtained at a significance level of 0.05 tcalculated = 2,900 and ttable = 2,010 which means H0 rejected. The conclusion of the research results is that the average learning outcomes of students who learn by using the Missouri Mathematics Project learning model are higher than the average learning outcomes of students who learn by using the direct learning model on the material of the system of linear equations of two variables.]]>

<![CDATA[Learning outcomes refer to the successful attainment of educational objectives by students who actively engage in the process of learning. Nevertheless, it is evident that student learning outcomes remain subpar, hence necessitating the implementation of a learning model aimed at enhancing student learning outcomes. The Group Investigation (GI) Learning Model is an educational approach that has been shown to enhance student learning results. The primary objective of this study was to assess the impact of implementing the Group Investigation (GI) Cooperative learning model and the direct learning model on the learning outcomes of eighth-grade students at SMP N 6 Tondano. Specifically, the study focused on the topic of straight-line equations. The research employed a Quasi-Experimental Design as its chosen methodology. The present study comprised two classes, namely class VIII B as the experimental group and class VIII A as the control group. The sampling methodology employed in this study was Cluster Random Sampling. The methodology employed in this study involves the utilization of written tests for the purpose of data collecting. Based on the findings of the study, the statistical analysis using the t-test yielded a t-value of 2.5709, while the critical t-value (t-table) was determined to be 2.0322. Consequently, the calculated t-value exceeded the critical t-value (t-count > t-table). This implies that the null hypothesis (H0) is rejected in favor of the alternative hypothesis (H1). Based on the findings, it can be inferred that students who were exposed to the Group Investigation (GI) cooperative learning model exhibited superior learning outcomes compared to students who were subjected to the direct learning model. This observation was made specifically in the context of studying straight-line equations among eighth-grade students at SMP Negeri 6 Tondano.]]>
