Abstract

The character of curiosity is inherent to support students in actively exploring an abstract concept such as mathematics. The lack of studies that discuss the importance of curiosity in students, which is the main urgency of the need to conduct this study to provide a reflection that there is a suboptimal character of curiosity itself. Thus, the purpose of this study focuses on describing the character of curiosity shown by analyzing 30 students at one of the Junior High Schools in Karawang Regency when mathematics lessons are taking place. Therefore, a descriptive qualitative approach was used with a simple random sampling technique for grade IX students. In data collection, a non-test instrument was used in the form of a questionnaire containing indicators of curiosity, including 1) Asking, 2) Reading from other sources, 3) Learning initiative 4) Desire to solve problems. The findings show the need for improvement in the character of curiosity because it is shown in one of the indicators of curiosity, namely reading from other sources, showing a percentage of 55%, meaning that only a large part has the desire to explore information from various existing references. Likewise with other indicators, it shows that most students still cannot be said to be optimal from the entire sample used.

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

The research's background is students' poor representation skills.  This investigation sought to determine how the Adversity Quotient (AQ) and Missouri Mathematics Project (MMP) learning models affected students' capacity for representation of mathematics. During the even semester of the 2023–2024 school year, this research was conducted at one of the MTs in South Tangerang City. Using the cluster random sampling method, 45 learners were chosen for the study, 23 of them were from the experimental class and 22 from the control class. Each class is divided into three levels of AQ which are students with Quitters, Camper, and Climber types. This study used a design similar to an experiment with a control group that was only included in the post-test. The data analysis technique used is two-way ANOVA testing. The findings of the investigation indicate that 1) students' mathematical modeling skills are influenced by their acquisition of model; 2) students' mathematical representation skills are influenced by the AQ type; and 3) there is no interaction effect between the AQ type and learning model on pupils mathematically illustration skills.

Abstract

Linear Algebra is often considered a difficult subject by students due to the complexity of its content and their limited problem-solving abilities. In addition to cognitive aspects, this ability is also influenced by affective factors, one of which is self efficacy. This study aims to investigate the problem-solving abilities of students in Linear Algebra, based on their self-efficacy levels. The research was conducted in the odd semester of the 2023/2024 academic year and involved participants from the 2022 cohort of the Mathematics Education Study Program who were enrolled in the Linear Algebra course. Data were collected through a self efficacy questionnaire, problem-solving tests, and interviews, and analyzed using the Miles and Huberman qualitative model. The findings indicate that students with high self efficacy demonstrated stronger abilities, especially in implementing solution plans and reviewing their answers. Meanwhile, students with moderate self efficacy tended to make calculation errors and were less likely to verify their results. These results suggest that self efficacy plays a significant role in comprehensive mathematical problem solving.
