Abstract

This study aims to develop web-based learning media in the form of e-learning on the topic of algebra to improve junior high school students' problem solving ability. This research uses a mixed method with the ADDIE development approach as well as an experiment with a pretest-posttest control group design. The research was conducted at MTs involving 20 students as samples. The results of the validation show that this learning media is valid, with a validation score from media experts of 92% and from material experts of 88%. The field test showed that the average student response was 71.7%, which was categorized as “good”. N-gain analysis showed an increase in students' ability to solve problems with an average score of 0.6724, indicating significant effectiveness. This research implies that web-based learning media can be an innovative solution to overcome challenges in learning mathematics in junior high school, especially on algebra topics that are often considered difficult. This media is able to motivate students, improve understanding, and provide flexible and interactive learning alternatives. However, further research is needed with a larger sample size to ensure the results can be generalized

Abstract

The purpose of this study is to determine the improvement of students' mathematical representation ability after applying the Problem Based Learning (PBL) Model in junior high school students. The research method used is a quasi-experimental research with a Control Group Pretest-Posttest Design. The sample of this study consisted of 30 students in the experimental class and 30 in the control class. The sample in this study was taken by simple random sampling. Data collection was used using a mathematical representation ability test sheet. The data analysis techniques used are the N-Gain test, and the independent t-test. The results of the study were obtained: (1) The application of the PBL model can improve the ability of mathematical representation with an average N-Gain value of 0.43 which is classified as "moderate", (2) Based on the independent t-test, obtained 0.000, it can be concluded that the mathematical representation ability of students who are taught the PBL model is better than the mathematical representation ability of students who are taught with regular learning.

Abstract

The low mathematical disposition of students is the background of this study. The aim is to analyze the mathematical disposition of students through a set of mathematical disposition scales using the Likert scale. 2 classes were taken as research samples through simple random sampling techniques. The research design used was Posttest-Only Control Design. The method used was the quasi-experimental method. The data analysis technique was descriptive statistics, then the Mann Whitney non-parametric test was carried out. A conclusion was obtained that the mathematical disposition of students with the application of the VBL method was better than the mathematical disposition of students with the application of the conventional method where the class with the VBL method showed a percentage of 76% in the moderate category and the class with the conventional method showed a percentage of 60% in the poor category.

Abstract

The low mathematical literacy ability is the background of this study. The aim is to create PISA type mathematics questions with quantity content using the context of Jambi's specialty coffee that are valid, practical, and have a potential effect on mathematical literacy skills. The study method used is the design research model development studies, namely preliminary, prototyping with a series of formative evaluation stages including self-evaluation, expert review, one to one, small group, and field test and assessment phase. The study subjects were 29 students of class VIII SMP N 22 Jambi City. Data were obtained using walk through, tests, questionnaires and interviews. This study presents PISA type mathematics questions with quantity content, especially the topic of comparison. The context is personal, namely Jambi's specialty coffee. The questions produced are included in the reasoning level category. The questions produced are valid and easy qualitatively and have a potential effect on mathematical literacy skills. In addition, by linking mathematics questions to contexts known to students, such as Jambi coffee, it makes it easier for students to understand abstract mathematical concepts.

Abstract

Finding out how well one can solve issues involving mathematical sequences and series is the primary goal of this study. The confidence that students feel after they have solved a problem is strongly correlated with their problem-solving ability, which is why this study was carried out. A quantitative technique based on survey methodology is used in this study. Thirty students from class IXA at SMPN 8 Pontianak made up the sample for this research, which used basic random sampling to determine the population. The tool used consisted of a 26-statement self-efficacy questionnaire with Likert scale measurements and a 4-question problem-solving skill test with four indications. The results were examined by using the Spearman Rank method to the collected data. Since the study data included both ordinal and interval variables, the Spearman Rank method was used. Findings indicated that self-efficacy and problem-solving skills were unrelated.

Abstract

This research aims to analyze and examine the improvement of seventh-grade junior high school students’ mathematical reasoning abilities using the problem-based learning model assisted by VBA for Excel, compared to the conventional learning model. The research method used is an experimental method with a quasi-experimental design, consisting of two groups, the experimental class and the control class. This research was conducted at SMP Negeri 2 Batujajar, with the sample comprising of class VII-D as the experimental class and class VII-B as the control class, each with 29 students. The instruments and learning materials used include a mathematical reasoning ability test and student worksheets (LKPD) containing material on plane figures according to the stages of problem-based learning. The data obtained will be analyzed using inferential statistics. The results of this research indicate that the improvement in students’ mathematical reasoning abilities using the problem-based learning model assisted by VBA for excel is better than that of those using conventional learning.
