Abstract

The purpose of this study is to ascertain how class IX students at SMP N 4 Sungai Penuh self-confidence and mathematical disposition relate to one another. The 113 pupils in class IX of SMP Negeri 4 Sungai Penuh comprised the study's population. This study will use a probability sampling technique, specifically simple random sampling with the use of the Solvin formula, to select 30 students to serve as the sample. Correlational research is the type of study that this study is. The F test significance test, the Pearson product moment correlation calculation, and a comparison with the F table are the steps in the data analysis procedure utilized in this study. The study's findings suggest that self-confidence and mathematical temperament have a positive but negligible impact on the mathematics learning achievement of SMP N 4 Sungai Penuh class IX pupils. The study's findings demonstrated that, at a significance level of 0.022 < 0.05, the self-confidence variable had a positive and substantial impact on learning achievement. The mathematical disposition variable likewise significantly and favorably affects student learning achievement. Student learning achievement was positively and significantly impacted by the variables of self-confidence and mathematical disposition, with a coefficient of determination of 0,428.

Abstract

In recent decades, attention to the preservation of local culture, especially in the context of education, has increased. This research explores ethnomathematics as a bridge between culture and mathematical concepts through traditional games. Ethnomathematics not only functions to understand mathematical concepts in a cultural context, but also to preserve traditions. The method used is a systematic literature study with qualitative analysis of 9 articles published between 2018 and 2024. The findings show that traditional games, such as marbles, congklak, and engklek, contain various mathematical concepts, including geometry, calculation, and logic. The results of this research provide new insights for educators about the importance of cultural context in mathematics learning, and encourage the development of a more inclusive curriculum. In addition, this research contributes to preserving local culture and increasing students' understanding of mathematics. By integrating traditional games in education, it is hoped that mathematics learning will become more interesting and relevant for students.

Abstract

This research aims to explore the ability to understand mathematical concepts between students with Feeling and Thinking personality types. The qualitative descriptive method with a case study design was applied to four students of SMA N 3 Sungai Full who were selected based on the results of the Myers Briggs Type Indicator (MBTI) test. The instruments used were personality type questionnaires, tests of ability to understand mathematical concepts, and unstructured interviews. Data analysis was carried out using data triangulation to ensure the accuracy and validity of the results. Students' understanding of mathematical concepts in the feeling and thinking aspects on the seven indicators that have been evaluated shows relatively low results, even though their approaches to learning are different. Students with the Feeling type tend to consider more emotional aspects in their understanding, while students with the Thinking type focus more on logic and analysis. This research underscores the importance of approaches tailored to students' personality types to improve their understanding of mathematical concepts.
