Abstract

This study aims to describe the thought process of students in solving problems in terms of personality types guardian and idealist in class XI SMA Negeri 5 Palu. This research is a qualitative descriptive research. The main instrument in this research is the researcher himself and supporting instruments are The Keirsey Temperament Sorter (KTS), math the problems, and interviews. The results of this study show that guardian students and idealist students are able to perform all stages of the thinking process in solving math problems, namely receiving information, processing information, and forming conclusions. Guardian and idealist students at the stage of receiving information read the problem well. Guardian students read enough once to understand the problem, while idealist students read repeatedly to understand the problem. At the information processing stage, guardian students can explain the problem solving plan while idealist students have difficulty explaining the solution plan. At the conclusion formation stage, guardian students consistently solve the problem according to what was previously planned. idealist students at the conclusion formation stage can solve the problem even though at the information processing stage they cannot explain the solution plan.

Abstract

Mathematical representation is a fundamental skill in mathematics learning, allowing students to express and solve problems through symbolic, verbal, and visual forms. However, students' varying levels of mathematical ability can significantly influence the quality of their representational skills. This study employed a descriptive qualitative method involving three eighth-grade students from SMPN 2 Kasimbar, selected based on their mathematical abilities: high, medium, and low. Data were collected through tests and semi-structured interviews, and analyzed using data condensation, data display, and conclusion drawing techniques. The results indicated that high-ability students could construct and solve systems of linear equations in two variables, although they exhibited some difficulty in interpreting variables accurately. Medium-ability students demonstrated proficiency in formulating equations and performing calculations, with particular strength in verbal and visual representations. In contrast, low-ability students struggled with algebraic operations, often misused variables, and were unable to generate appropriate graphical representations. These findings highlight the significant role of mathematical ability in shaping students’ representation skills and underscore the need for teachers to implement more adaptive and differentiated instructional strategies.

Abstract

Pendidikan yang efektif memerlukan pendekatan yang relevan dengan keberagaman budaya peserta didik, terutama untuk meningkatkan pemahaman konsep abstrak seperti penyajian data. Namun, dalam praktiknya, pembelajaran matematika sering kali bersifat monoton dan kurang mengaitkan materi dengan latar belakang budaya peserta didik, sehingga menyebabkan rendahnya hasil belajar. Penelitian ini bertujuan untuk mendeskripsikan penerapan Culturally Responsive Teaching (CRT) melalui model Problem-Based Learning (PBL) dalam meningkatkan hasil belajar peserta didik pada materi penyajian data. Penelitian ini menggunakan jenis penelitian tindakan kelas (PTK) dan dilaksanakan dalam dua siklus. Setiap siklus terdiri dari empat tahap yaitu merencanakan, melaksanakan, mengamati, dan merefleksikan. Subjek penelitian adalah peserta didik kelas VII yang berjumlah 30 orang, sedangkan instrumen yang digunakan meliputi lembar observasi dan tes hasil belajar. Hasil penelitian menunjukkan bahwa penerapan pendekatan CRT melalui model PBL secara signifikan meningkatkan hasil belajar peserta didik. Pada siklus I, terdapat 14 peserta didik (53,3%) yang mencapai ketuntasan belajar, sedangkan pada siklus II jumlah tersebut meningkat menjadi 24 peserta didik (86,7%).

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

This study aims to describe the profile of students who have Field Independent (FI) and Field Dependent (FD) cognitive styles in solving integer counting operation problems. This type of research is descriptive research. The approach used in this study is a qualitative approach. The results of this study show the profile of student problem solving with FI and FD cognitive styles in solving integer counting operation problems. (1) Student problem-solving profile with FI cognitive style in solving integer counting operation problems. Subject FI can determine and declare the elements that are known, that are questioned, and the sufficiency of other elements. Subject FI shows good ability in implementing problem-solving strategies with correct and thorough steps. Subject FI can explain the results of the completion orally and in writing. (2) Student problem-solving profile with FD cognitive style in solving integer counting operation problems. Subject FD can determine and state the elements that are known, that are asked, and the sufficiency of other elements, even though Subject FD reads the question repeatedly and takes a little longer, but Subject FD seems to understand the problem because it can determine and express the information from the question. Subject FD can compile a mathematical model from the problem. However, the mathematical model that was written did not use parentheses, so the sequence of operations did not correspond to the context of the story. Subject FD is still wrong in solving the problem so that the answers obtained are not correct. Subject FD can explain the results of the settlement orally, but does not write them in writing on the answer sheet.

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.
