Abstract

This study aims to analyze the level of students' understanding of mathematical concepts systematically. The research sample consisted of thirty ninth-grade studentsof SMP Muhammadiyah 3 Bandar Lampung who were selected through purposive sampling technique. This study employs a quantitative approach, utilizing standardized tests and statistical analysis to measure and analyze the phenomenon in depth. The data used in this study include quantitative data in the form of test results that measure the level of students' understanding of mathematical concepts. Based on the results of the analysis and discussion, it was found that the level of students' understanding of mathematical concepts was still in the low category.

Abstract

This study aims to analyze how junior high school students express their ideas when solving problems related to the System of Linear Equations in Two Variables (SPLDV). Mathematical Representation Ability is essentially a "bridge" for students to transform difficult and abstract mathematical concepts into more real and simple forms, whether through images, symbolic formulas, or written explanations. SLETV was chosen due to its characteristics that involve complex word problems, requiring students to be proficient in converting long narratives into correct mathematical models. Through a literature review method analyzing various previous research findings, it was found that students' representation abilities are heavily influenced by their basic mathematical proficiency levels. High-achieving students are generally proficient in using symbols and graphs, yet they still face challenges in providing narrative explanations for their reasoning. Meanwhile, low-achieving students and slow learners show significant obstacles in initiating problem-solving, thus requiring specific assistance or scaffolding.

Abstract

This study aims to describe the reflective literacy profile of seventh-grade junior high school students in solving mathematical problems on the topic of data presentation by analyzing three main indicators: reacting (understanding problem information), comparing (connecting information with mathematical concepts and selecting strategies), and contemplating (monitoring problem-solving steps and evaluating final answers). A quantitative descriptive design was employed, involving 32 students and a 10-item essay instrument tested for validity and reliability. Results show an average reflective literacy score of 31.00, classified as moderate, with 15.63% of students in the high category, 59.38% in the moderate category, and 25.00% in the low category. Indicator analysis revealed the highest achievement in reaction (64.58%), followed by comparing (62.08%) and contemplating (60.00%), indicating that evaluation and monitoring skills still require improvement. These findings suggest the need for mathematics instruction emphasizing reflective activities, such as metacognitive questioning, reflection journals, group discussions, self-assessment, and answer review, to enable students to better understand, manage strategies, monitor processes, and evaluate solutions effectively.
