Abstract

This study aims to describe the mistakes of class VII students of SMP Negeri 1 Tondano in solving questions on the Algebraic Forms material in the bold and alluring learning process. The errors referred to here may occur in solving Algebra Form problems, including principle and concept errors. The type of research used is descriptive research with a qualitative approach. Data collection techniques are carried out through tests, interviews, and documentation. The sources and subjects of this study were class VII students of SMP Negeri 1 Tondano T/A 2020/2021 and T/A 2022/2023, who were selected based on considerations. Data analysis techniques in this study are the stages of data reduction, data presentation, and conclusions. The results of this study indicate that the mistakes made by students are: 1) conceptual errors, where they cannot identify elements in the algebraic form, such as terms, variables, coefficients, and constants. 2) the principle of error, where it is wrong to operate algebraic forms that have negative terms, and errors in determining operations on terms that are not similar. The causal factors in brave learning are: 1) working on questions in a hurry; 2) do not understand the concept in Algebraic Forms; 3) do not know how to operate tribes that are not of the same type; 4) do not know the correct settlement calculation operating procedure; 5) not careful in working on the questions; 6) ambient distractions that make it out of focus. The causal factors in engaging learning are: 1) Class conditions are not conducive; 2) decreased student discipline.

Abstract

Students' information gathering is heavily reliant on their learning styles. Mathematical education calls for a deeper examination of methodological variations. This study examines the correlation between students' learning styles and their ability to solve math word problems involving a system of two-variable linear equations. The method employed is a qualitative, descriptive research method. The instruments utilized are student aptitude and learning style assessments. Data analysis methods include data collection, data reduction, and data interpretation. The findings included that the visual and auditory subjects completed only three of the five questions they deemed simple. Comparatively, kinesthetic subjects were able to answer four questions. When reexamining the visual, auditory, and kinesthetic subjects, the obtained answers are not rechecked. By concluding the solution process, visual and kinesthetic subjects exhibit similarities. In the final phase, the auditory subject neither concludes nor responds to the initial questions.

Abstract

This research aims to determine the differences in student learning outcomes in junior high school after receiving learning using the Problem-posing model and the direct learning model on Association material. The research method used in this research is a quasi-experiment with a Posttest Only Control Design by applying the Problem Posing learning model and the Direct learning model. In this research, the author used two sample classes, namely VIIA, using the Problem-solving learning model as the experimental class, and VIIB, using the direct learning model as the control class. The instrument used is four descriptive questions whose validity and reliability have been tested and scored. The results of data analysis show that the average student learning outcomes in the experimental class are 80.20 higher than the average student learning outcomes in the control class, namely 75.95; this indicates differences in student learning outcomes in the set metrics by applying the Problem-posing learning model. The results of data analysis using the Liliefors test and t-test show that the data obtained in this study is normally distributed, which means that applying the Problem-posing learning model influences students' ability to solve Association questions at St. Catholic Middle School.

Abstract

The objective of this study is to analyze the disparities in the mean learning achievements between students who utilize the SOLE learning model and those who employ the direct learning model for arithmetic sequence material at Tondano State Vocational School. The research employed a quasi-experimental design with a Posttest Only Control Group Design. The participants in this study consisted of students from class X OTKP 1, who were assigned to the experimental group, and students from class X OTKP 2, who were assigned to the control group. The data gathering method involved administering a technical learning outcomes test at the conclusion of the class (Posttest). The data analysis technique employed in this research utilizes tests on data that has undergone normality and homogeneity testing. The t test calculations yielded a t_count value of 2.736, which exceeded the critical t_table value of 1.685. Therefore, the null hypothesis (H_0) was rejected, and the alternative hypothesis (H_1) was accepted. Therefore, it can be inferred that there is a disparity in the mean learning results of students in the Self-Organized Learning Environment (SOLE) instructional approach and the traditional direct learning approach when it comes to arithmetic sequence material.

Abstract

This research aims to determine the differences in the average learning outcomes of students taught using the Problem Posing learning model on flat-sided geometric material at Woloan Christian Middle School. This research used the experimental method on class VIII students at Woloan Christian Middle School. The samples in the study were class VIII-A as an experimental class with a total of 31 students and class VIII-B as a control class with a total of 31 students, a total of 62 students at Woloan Christian Middle School, even semester of the 2023/2024 academic year. The instrument used in this research consisted of a learning outcomes test in the form of a written test in the form of an essay with flat-sided geometric material. The technique for collecting observation and test data is in the form of evaluation questions. The test is carried out twice. Namely, the pretest is carried out at the beginning of the research to determine students' achievement scores before treatment, and the posttest is carried out on both control and experimental groups after treatment. Based on hypothesis testing using SPSS test statistics, where from the calculation results of the Tcount value of 1.822 with Ttable 1.671 (1.822>1.671), it can be said that there is a significant difference in the average learning outcomes of the experimental group using Problem posing and the control group using the learning model. Direct Instruction, which means that there is an influence of the application of the Problem posing learning model on the average learning outcomes of class VIII students at Woloan Christian Middle School

Abstract

This research examined the average student mathematics learning outcomes when the Project Based Learning Model was applied in mathematics learning with Cube material. The research design used was Posttest Only Control Group Design. The population in this study was all class VIII at SMP Negeri 3 Bolaang. In contrast, the samples taken in this study were class VIII B, with 20 students as the experimental class and class VII A as the control class, with a total of 20 students. The analysis results from this research show that the average posttest score for the experimental class is 82.75, while the average posttest score for the control class is 73.25. The research results obtained were based on hypothesis testing using the T-test with a significance level of 5%. The value obtained was ????ℎ???????????????????? = 4.407 > ???????????????????????? = 1.68595, so reject ????0. So, it can be concluded that based on these results, the Project Based Learning model can improve student learning outcomes
