Abstract

Misconceptions in solving linear programming problems remain a challenge in mathematics education. Conceptual errors made by students can lead to misunderstandings and suboptimal learning outcomes. This study aims to identify students' misconceptions in solving linear programming problems based on the Newman method and analyze them from a gender perspective. The research method used is qualitative descriptive, with research subjects consisting of high school students who have studied linear programming. Data were collected through a diagnostic test based on the Newman method and in-depth interviews. The Newman method was used to analyze students' errors in five stages: reading, comprehension, transformation, process skills, and writing the final answer. The results showed that misconceptions most frequently occurred in the transformation and process skills stages. Male students tended to make errors in process skills, while female students made more mistakes in the comprehension and transformation stages. The conclusion of this study indicates that gender influences students' misconception patterns in solving linear programming problems. These findings are expected to serve as a reference for educators in designing more effective teaching strategies to reduce misconceptions and improve students' understanding of linear programming.

Abstract

Difficulties in understanding fraction concepts remain a significant challenge for elementary school students, primarily due to limitations in connecting abstract ideas with concrete experiences. This study aims to examine the implementation of GeoGebra and manipulatives blocks as visual and concrete representations in teaching fractions at SD Negeri 35 Ampenan. Employing a case study approach, the research involved 25 fourth-grade students as participants. Data were collected through observations, written tests, in-depth interviews, and documentation. The findings reveal: (1) an improvement in learning outcomes, indicated by an increase in average test scores from 72.2 (using manipulatives blocks) to 78.4 (using GeoGebra), representing an 8.6% gain; and (2) interviews with three students of varying ability levels suggested that concrete media (manipulatives blocks) were more effective for students with lower mathematical ability, while GeoGebra was preferred by students with stronger visual and conceptual skills. These findings suggest that the use of multiple representations can bridge understanding gaps and provide a more adaptive learning experience, particularly in teaching fractions. The study recommends integrating both visual and concrete media into mathematics instruction to enhance instructional effectiveness and strengthen student engagement.

Abstract

Duality in linear programming is an essential concept in optimization-based decision making. However, many undergraduate students still struggle to understand and solve duality problems, especially when converting primal to dual models and interpreting their results. This study aimed to explore the learning strategies used by fifth-semester students in solving duality problems. A qualitative case study approach was employed, involving 36 students from a mathematics education program. Data were collected through classroom observations, open-ended tasks, reflective writing, and interviews, and analyzed thematically. The findings revealed that most students (52.8%) used procedural repetition strategies, while others adopted conceptual elaboration (30.6%) and organizational strategies (16.6%). Students who used elaboration and organizational strategies demonstrated deeper conceptual understanding and greater problem-solving flexibility. These results suggest that procedural approaches still dominate, and instructional efforts should focus on fostering more reflective and meaningful learning strategies among students.
