Abstract

Abstract: The purpose of this study was to determine the misconceptions made by Unisa Mathematics Education students about the concept of limit.  The research method used was a descriptive qualitative approach or survey design, where data were collected through comprehension tests, interviews, and observations of 16 students. The results showed that students consider limit as something that is not reached, limit is an estimate, limit is a boundary, and a function will always have a limit at a certain point. Other misconceptions are that students consider limit as a substitution process, even though the substitution process causes the denominator to become 0, students still write 0, and they think that when the function has a limit value, the function is defined at a certain point and must be continuous. These findings are expected to contribute to the development of more effective learning strategies to overcome misconception in Mathematics Education students and improve their understanding of calculus concepts, especially function limit.       Keywords: limit concept, limits of functions, misconceptions.

Abstract

A deep understanding of prime numbers remains a significant challenge, particularly for pre-service mathematics teachers responsible for conveying this essential knowledge to their students. Prime numbers have an essential role in mathematics, including in factorization, proof, and cryptography. Therefore, this study aims to describe and analyze the representational abilities of prospective mathematics teacher students at Alkhairaat University, regarding the prime numbers in Number Theory. This study uses a descriptive exploratory method with a mixed-methods approach based on a sequential explanatory design. Data collection was carried out through diagnostic tests, semi-structured interviews, and documentation, which were then analyzed using descriptive statistics for quantitative data and the Miles & Huberman model for qualitative data. Triangulation of methods and time was used to ensure the validity of the data. The findings showed that out of 17 students, only 29.41% were able to provide accurate verbal representations related to the prime and composite numbers, and only 5.88% were able to link the two meaningfully. In addition, while students were able to mention definitions, most of them had difficulties applying the prime numbers in the abstract problem context, including examples in algebraic notation. This study concludes that there is still a significant gap in the representation ability of prime number concepts of pre-service mathematics teachers. The implications emphasize the need for integrating multidimensional representation learning strategies into the mathematics education curriculum so that prospective teachers are better prepared to teach prime numbers in a comprehensive and meaningful way.    Keywords: representation, prime numbers, number theory, pre-service mathematics teachers.

Abstract

The quality of measurement in educational research is highly dependent on the validity and reliability of the instruments used. However, in practice, many numeracy literacy and problem-solving instruments have not undergone adequate psychometric testing, particularly those that use cultural contexts as question stimuli. This study aims to develop and evaluate instruments for numeracy literacy and problem-solving in sequences and series, grounded in cultural context/local wisdom, using a research and development approach and Rasch modeling. The instrument's content validity was assessed through expert review by learning evaluation experts, mathematics education lecturers, and cultural experts (traditional councils). The analysis was conducted using the average validator score, Aiken's V coefficient, and percentage agreement to ensure the appropriateness of the substance, clarity of language, instrument appearance, and the appropriate integration of cultural context. Empirical trials were conducted in small groups with 71 high school students in grade X with 15-17 years in three regions in Indonesia: Palu City, Donggala Regency, and Sigi Regency, who were selected purposively. The test data were analyzed using Rasch modeling to evaluate item suitability, difficulty level, reliability, separation index, unidimensionality, and potential bias through DIF analysis. The analysis results showed that the developed instrument had very high content validity, strong person and item reliability, and that most items fit the Rasch model. However, the distribution of item difficulty did not fully cover the extreme range of respondents' abilities, and indications of DIF were found in some items in one area, indicating the need for further refinement. Thus, the developed numeracy literacy and problem-solving instrument was deemed suitable based on initial findings at the development stage; however, it still requires further revision and testing before being widely used in a more diverse population. Keywords: numeracy literacy, problem-solving, rasch model, reliability, validity.
