Abstract

Normality testing is an essential part of statistical analysis to determine whether observed data are normally distributed or not. This study aims to document and analyze various types of errors frequently made by non-mathematics students when conducting normality tests. Furthermore, this descriptive qualitative research involved 32 second-year non-mathematics students as participants, who were given tasks requiring them to perform normality tests on datasets. The research findings indicate that the most common type of error made by non-mathematics students in conducting normality tests is encoding error, accounting for 40.7% of errors. This occurs when students mistakenly compare decimal values between Lcalc and Ltable. Consequently, the conclusions drawn from these normality tests may be inaccurate. Additionally, other types of errors identified include reading error, comprehension error, transformation error, and process skills error.

Abstract

This study aims to analyze students' errors in solving Ordinary Differential Equations (ODE) problems based on the SOLO taxonomy (Structure of the Observed Learning Outcome). This qualitative descriptive research involved 29 students from the Mathematics Education Study Program at the University of Mataram. Data were collected through essay tests and interviews, then analyzed using the SOLO taxonomy classification and error types based on the framework by Subanji and Mulyoto. The results show that most students were at the pre-structural, uni-structural, and multi-structural cognitive levels, with a dominance of conceptual and technical errors. Common mistakes included the use of incorrect formulas, errors in algebraic manipulation, and weak fundamental calculus skills. A lack of understanding of prerequisite concepts such as algebra and calculus was identified as the main factor contributing to these errors. These findings highlight the importance of strengthening basic concepts and implementing learning strategies based on the SOLO taxonomy to improve students' understanding of ODE topics

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.
