Building Numerical Skills in Ethnomathematics Learning in Engklek Games

2025-01-23T09:10:06+07:00

This research aims to explore the numerical abilities of elementary school students through ethnomathematics learning in the engklek game. Ethnomathematics is a learning approach that integrates cultural and mathematical elements to improve understanding of mathematical concepts. Engklek, as one of Indonesia's traditional games, has the potential to be used as a fun and contextual learning medium for students. Through a literature review, this research analyzes various relevant literature to explore the relationship between the crank game and students' numerical abilities. The research results show that the integration of engklek games in mathematics learning can increase students' learning motivation, facilitate understanding of numerical concepts, and develop critical thinking and logistics skills. These findings have an impact on developing a more inclusive and contextual curriculum by incorporating cultural elements in mathematics learning at the elementary school level.

Development of Interactive Video Learning Media for Seventh-Grade Middle School Students

2025-06-11T10:52:35+07:00

Mathematics is an important field of knowledge, yet in reality, math lessons are less popular, feared, and boring for students. The use of teaching media in the math learning process can assist teachers in improving students' learning outcomes. Therefore, a teacher must be able to choose or create appropriate teaching media for the students. From the problems presented, there is a need to develop visualization media designed as interactive video learning media.

Analysis of Critical Thinking Ability in Solving Linear Inequalities with One Variable Reviewed From a Mathematical Disposition

2025-01-23T15:58:17+07:00

Abstract

This study aims to describe students' critical thinking skills in solving linear inequality problems with one variable in terms of mathematical disposition. This type of research is quantitative-qualitative research. The subjects in this study were three students selected from 31 students in class VIII-4 of SMP Negeri 4 Ambon with categories of high, medium, and low mathematical disposition. The results of the study showed that subject JA, with a high mathematical disposition showed that he could fulfil every indicator of critical thinking. Subject JFT, with a medium mathematical disposition category, showed that he could fulfil the critical thinking indicator on some questions and could not fulfil the critical thinking indicator on other questions. Meanwhile, subject JK, with a low mathematical disposition category, could only fulfil two indicators of critical thinking. Based on the percentage of the results of filling out the mathematical disposition questionnaire, the high mathematical disposition category is 41.94%, the moderate disposition category is 48.39%, and the low disposition category is 9.68%, which means that the largest percentage of mathematical disposition of class VIII-4 students is in the moderate mathematical disposition category.

Numeracy Literacy Ability of High School Students in Solving Statistics Questions

2025-01-24T18:16:02+07:00

Numeracy literacy skills refer to an individual's ability to understand, interpret, and apply mathematical concepts, numbers, and data in everyday life to make appropriate decisions and solve practical problems. This study aims to describe the numeracy literacy abilities of class XII students of senior high schools in Ambon City in solving statistical problems using a qualitative descriptive research design. The data sources include the mathematics teacher and the students. The subjects, selected based on test results, consisted of 22 students. Data were collected through written tests containing three questions related to statistical material and interview results. The data were analyzed through data reduction, data presentation, and conclusion drawing stages. The results show that high-performing students were able to meet all numeracy literacy skill indicators, students with moderate ability were unable to use various mathematical numbers or symbols to solve real-life problems and were unable to analyze information in various forms (graphs, tables, charts, diagrams, etc.), while low- performing students fail to meet all numeracy literacy skill indicators. Therefore, the numeracy literacy ability of the high school students was categorized as low, at 22.58%.

Critical Thinking Ability of Students on Probability Material in Class XII SMA Negeri 1 Ambon

2025-01-23T15:54:23+07:00

This study aims to describe the critical thinking skills of students on opportunity material in class XII SMA Negeri 1 Ambon. The type of research used is descriptive qualitative research. The research subjects, namely students of class XII-F10 SMA Negeri 1 Ambon, totaling 3 people. The subjects in this study were selected through purposive sampling based on the categorization of the test results of students' critical thinking skills supported by the results of observations from researchers while teaching in class XII-F10 and opinions from subject teachers. The object of this research is the critical thinking ability of students measured through research instruments in the form of test questions and interview. Data analysis with data reduction, data presentation, and conclusion. The results showed that subject DF, with high critical thinking ability, showed good performance in analyzing, evaluating, and drawing logical conclusions, although there were deficiencies in the interpretation indicator. HPH subject, with moderate critical thinking ability, was good in analysis and evaluation indicators but still needed improvement in interpretation and inference. Meanwhile, the JCP subject, who has low critical thinking ability, had difficulty interpreting the problem and applying the solution completely and did not draw clear conclusions on the inference indicator. The results of this study also indicate the need to develop critical thinking skills on the inference indicator.

Meta-Analysis: Effectiveness of ICT-Based Learning Learning Model on Students' Mathematical Ability

2025-05-21T09:22:09+07:00

The purpose of this study is to determine the effectiveness of the ICT learning model on students' mathematical potential. The type of research used is meta-analysis. The Publish or Perish (PoP) database and Google Scholar are reviewed to achieve appropriate research within the scope of the research. By inputting keywords that have existed in this database, approximately 200 articles have been found that have been published around 2014 to 2023 and have been researched for research goals. Based on the inclusion conditions, 22 articles have met the suitability requirements for research. The software used as an analysis tool is the Comprehensive Meta-Analysis (CMA) version 3.7, and the effect size index of the Hedges-g Coefficient equation is obtained from the determination through the estimation of the random-effect design. The results of the study found that the overall effect measure of ICT use on students' mathematical ability was 0.498, with a confidence level of 95%. These findings indicate that the use of ICT in Indonesia or abroad is still quite effective because it has a positive impact on students' mathematical skills. Thus, the application of ICT has a greater effect on mathematical abilities than conventional approaches.
