Abstract

This study aims to analyze the pedagogical competence of mathematics teachers and students' numeracy level in solving numeracy problems. The research was conducted in one junior high school in Bandung using a qualitative approach and case study design. The subjects of this research were 16 students in grade VIII and one math teacher at a junior high school in Bandung. Data were collected through observation, numeracy tests, and interviews. The numeracy test results showed that four students had a low numeracy level, six were medium, and six were high, with an average numeracy score of 70.625, which was in the medium category based on the indicator scale. Observations and interviews revealed that teachers have good pedagogical competence. Teachers can design learning according to the curriculum, use methods that actively involve students, and provide constructive feedback. However, test results show variations in students' numeracy levels that require adaptive learning strategies significantly to help students with low numeracy. This research emphasizes the importance of problem-based and differentiated learning approaches to improve students' overall numeracy ability. In addition, further evaluation of other factors, such as motivation and learning environment, which may affect students' numeracy ability, is needed.

Abstract

The topic of linear equations with one variable is studied at the junior high school level. This topic is essential as it can be applied to solve various real-life problems. However, many students struggle to master this concept, often due to various learning obstacles. This study aims to describe the learning obstacles faced by students in understanding linear equations with one variable in the context of mathematical literacy. The method of research used is a descriptive method with a qualitative approach. The research subjects were six eighth-grade students from a junior high school in Bandung. Data were collected through written tests and interviews. The results revealed five types of learning obstacles related to the material of linear equations with one variable based on mathematical literacy. These obstacles include: difficulties in forming equations, inaccuracy in reading or understanding questions, and challenges in concluding. Additionally, students faced difficulties in understanding the relationships between different concepts and in understanding what needs to be done. To overcome these learning obstacles, several efforts can be made, including transforming abstract concepts into concrete and visual representations, improving interactive and contextual problem-based teaching methods, and offering varied exercises. These strategies are expected to significantly enhance students' mathematical literacy and reduce learning obstacles.

Abstract

This study addresses the challenge of accurately identifying eligible awardees of the KIP-K scholarship at UIN Sjech M. Djamil Bukittinggi, where scholarship aid requests exceed the allocated funds. The research aims to develop an integrated classification and decision-making model to optimize the selection process. From the 2022 and 2023 scholarship applicant data obtained through AKAMA, preprocessing was conducted, resulting in a final dataset comprising 2,144 records. The dataset includes 14 explanatory variables influencing scholarship eligibility. The study compares three classification methods—logistic regression, classification tree, and boosting—using the 2022 data for training and testing. The SMOTE resampling technique was applied to address class imbalance. The novelty of this research lies in integrating classification analysis with a decision-making system based on the Simple Additive Weighting (SAW) method, enhancing the ranking of applicants based on criteria. The results indicate that logistic regression delivered the best performance in terms of accuracy, sensitivity, and AUC-ROC scores during testing, despite a slight decline in performance when applied to the 2023 dataset. Moreover, integrating logistic regression with SAW significantly improved decision-making precision. The application of logistic regression combined with SAW on the 2023 dataset resulted in a final accuracy of 0.5734 and a balanced accuracy of 0.5820. This integrated framework provides a data-driven, fair, and efficient approach to scholarship allocation. The study highlights the importance of combining predictive models with decision-making systems to ensure equitable and targeted distribution of financial aid to deserving students.

Abstract

Mistakes frequently occur among students when interpreting mathematical problems or engaging with math exercises. This has contributed to the low PISA results in 2022, particularly reflected in a decline in mathematical proficiency, with Indonesia's average score decreasing by 1-3 points compared to previous assessments. Consequently, there is a pressing need to investigate the errors committed by students. This study aims to identify student errors through the lens of Newman's theory while addressing critical thinking ability questions in relation to cognitive style. The research design is descriptive qualitative, as it elucidates the mistakes made by students. The subjects of this study comprised 27 out of 84 seventh-grade students from SMP Negeri 139 Jakarta, who exhibited errors in responding to critical thinking ability questions involving combined material on flat-sided geometric shapes. The findings and conclusions of this study reveal that students with a Field Dependent (FD) cognitive style and those with a Field Independent (FI) cognitive style encounter reading errors, understanding errors, process skill errors, and coding errors; however, students with an FI cognitive style tend to make fewer mistakes than their FD counterparts.

Abstract

Problem-solving abilities are one of the requirements that must be owned in facing the 21st century. In order for the problem-solving ability to be owned by everyone, it needs to be developed from school age. However, in fact, students' problem-solving ability is still low, especially in solving numeracy literacy problems. In addition, to prove problem-solving ability, habits of mind are needed as an attitude that allows individuals to develop behavioral intelligence based on stimulus in the process of solving problems. This study aims to describe and analyze students' problem-solving ability in solving numeracy literacy problems based on Polya's Theory in terms of habits of mind. The research questions are: 1) How is the problem-solving ability of students who have high habits of mind? 2) How is the problem-solving ability of students who have moderate habits of mind? and 3) How is the problem-solving ability of students who have low habits of mind? The subjects of this study were 28 eighth-grade students in one of the junior high schools in Bandung City, West Java. Data collection in this study used numeracy literacy problem-solving ability tests, habits of mind questionnaires, and interview guidelines to confirm the problem-solving ability tests and habits of mind questionnaires. The analysis results showed that: 1) Students with high habits of mind have high and moderate problem-solving ability; 2) Students with medium habits of mind have high and medium problem-solving ability; and 3) Students with low habits of mind have medium and low problem-solving ability.
