Abstract

This research aims to analyze students' difficulties related to mathematical dispositions and measure students' abilities in solving problems related to three-variable linear equation systems based on mathematical dispositions. Descriptive analysis methods are used in this qualitative research. All X-G students were given a mathematical disposition survey as part of the data collection process for this research. Three students were selected from each mathematical disposition category to take a test of their contextual problem-solving skills. Based on the results of the research, there were three groups of students in class X-G SMAN 1 TOROH, namely 3 students with high mathematics dispositions, 14 students with medium mathematics dispositions, and 16 students with low mathematics dispositions. Based on the analysis of answers and discussions, students with strong mathematical skills have excellent problem-solving skills because they meet three problem-solving indicators, namely making a problem-solving plan, implementing a problem-solving plan, and evaluating problems. Students have difficulty in the indicator of understanding problems because they are not used to writing what they know and what is asked. Students with a moderate mathematical disposition meet two indicators of problem-solving, namely creating and implementing a problem-solving plan, so they are in the moderate category in terms of problem-solving. Students with moderate mathematical dispositions also have difficulty writing the conclusion of the problem. Because students with low mathematical dispositions only fulfill one indicator, namely evaluating the problem, these students have problem-solving skills in the low category. In addition, students with low mathematical dispositions had difficulty in applying the formula.

Abstract

Middle school students often encounter dificulties in solving integer operation problems, such as understanding concepts like positive and negative integers and correctly applying arithmetic symbols. This study utilizes a Systematic Literature Review (SLR) approach to analyze these difficulties, searching academic databases like Google Scholar, ResearchGate, and Sinta for relevant articles published from 2019 to 2023 and included articles published in 2024 . Articles were selected based on criteria assessing their relevance to the research topic, methodological rigor, and contribution to understanding students' struggles in integer operations. The research identifies three main difficulties: conceptual comprehension, handling factual knowledge, and procedural application. Many students struggle with applying learned concepts, differentiating between positive and negative integers, and using arithmetic symbols accurately. Factors contributing to these difficulties include a lack of seriousness in problem-solving, reliance on peers for answers, and hesitancy in seeking assistance from teachers. The study recommends reinforcing fundamental concepts through diverse teaching methods, fostering student independence in mathematical problem-solving, and developing critical thinking skills to support students in overcoming these challenges and improving their mathematical proficiency.

Abstract

One learning approach that can be applied to learning mathematics is reciprocal teaching because it is efficient in helping students become independent learners and developing students' courage in expressing opinions. Many studies have discussed Reciprocal Teaching with mathematics learning outcomes in primary and secondary schools with different conclusions. This study aimed to determine the effect of the Reciprocal Teaching model on students' mathematics learning outcomes. This study used a meta-analysis, a statistical analysis method that synthesizes data from several studies to obtain stronger findings. The sample in this study were articles that met the inclusion criteria and obtained as many as 8 articles. Data were analyzed using JASP V-0.18 software. The results showed that the Reciprocal Teaching model affected students' mathematics learning outcomes, with an effect size of 1.07 and a high effect size category. However, this analysis did not include some related studies because they did not meet the inclusion criteria. Therefore, further research using a larger sample size and a wider variety of studies is needed to gain a more thorough understanding.

Abstract

This research is motivated by the students' self-assurance in the acquisition of mathematics and their limited mathematical representation ability. The objective of this study is to examine the relationship between self-assurance and mathematical representation skill with the goal of utilising it as a model to improve mathematical representation ability. The research investigated the capacity for mathematical representation in terms of verbal and visual representation. Correlational quantitative research is implemented in this investigation. A self-confident questionnaire and a written exam of mathematical representation ability were implemented as the data collection methodology. The subjects they studied were those of the ninth-grade students at SMP Muhammadiyah 4 Pekanbaru. Self-confident questionnaires were disseminated to gather data, and the mathematical representation ability test was administered in the form of description questions. The impact of self-confidence on learning outcomes is 91.6%, as indicated by the results of simple linear regression and simple correlation analysis. The learning outcomes of mathematical representation are influenced by 8.4% of other variables and are not specific to this case.

Abstract

Self-confidence is a critical factor in mathematics learning, influencing students' engagement and performance. However, studies show that Indonesian students often lack confidence in mathematics subject, hindering their academic potential. Accurate instruments are needed to measure and address this issue effectively. This tudy aims to develop a self-confidence measurement instrument for mathematics learning among secondary school students. The instrument comprises 25 statements categorized into four main aspects. The research employs a descriptive quantitative method with the Rasch Model approach and utilizes exploratory and confirmatory factor analysis. The sample consists of 122 randomly selected tenth-grade students in Yogyakarta. The results indicate that the developed instrument has high validity, with an Aiken's V coefficient of 0.99, and very high reliability, evidenced by a Cronbach's Alpha coefficient of 0.845 with a total of 18 items used. Factor analysis shows that the items in the self-confidence questionnaire meet the unidimensionality requirement, although some items need correction to enhance measurement accuracy for one self-confidence indicator. Overall, this instrument provides a valid and reliable tool for measuring students' self-confidence in mathematics learning, potentially contributing to the enhancement of students' confidence in this subject. So that, 18 statements are more efficient to use, without reducing the scope of the self-confident aspect being measured. The results allow the use of instruments for various levels of education and support the implementation of more personalized learning strategies.

Abstract

Mathematics, often perceived as abstract and daunting, can be made more engaging and relevant through its integration with cultural contexts. Ethnomathematics, the study of mathematics embedded in cultural practices, offers a promising approach to enhance student motivation and understanding. This study investigates the potential of the traditional Indonesian Congklak game to teach fundamental mathematical concepts (multiplication, division, GCF) within an ethnomathematics framework. By analyzing game mechanics and observing student engagement, the study demonstrates Congklak's effectiveness in fostering positive attitudes towards mathematics, enhancing problem-solving skills, and promoting deeper conceptual understanding. While previous research has explored Congklak in mathematics education, the novelty of this study lies in its specific focus on analyzing the game's rules to explicitly demonstrate how it embodies and reinforces key mathematical principles. This approach provides a more nuanced understanding of Congklak's pedagogical value and offers a replicable model for integrating other traditional games into mathematics curricula.
