Abstract

Mathematical creative thinking ability is a student's ability to create or find new ideas in solving a problem. Everyone must have the ability to think creatively, especially students. The ability to think creatively plays an important role in the progress of every student. However, in reality, many students are not able to solve a problem using their creative thinking skills. This is possible because students do not get used to thinking (habits of mind). This research aims to determine students' mathematical creative thinking abilities in solving circle problems in terms of habits of mind. The method used in this research is a qualitative method with a case study type of research. There are three data collection techniques used, namely: tests, questionnaires and interviews. The results showed that 6 subjects who had high habits of mind were able to show all indicators of mathematical creative thinking ability, 12 subjects who had moderate habits of mind were able to show three indicators of mathematical creative thinking ability and 3 subjects who had low habits of mind were only able to show one indicator of mathematical creative thinking ability. So, habits of mind have an impact on students' mathematical creative thinking abilities.

Abstract

This research explains students' mathematical proficiency by considering mathematical resilience in solving problems. This research sample involved 30 grade 8 junior high school students in Pringgarata, who were chosen randomly. The research method used is descriptive qualitative. Data was collected through a mathematical resilience questionnaire with 12 statements, as well as a mathematical proficiency test consisting of 2 essay questions and an interview guide. The research results show that students with high mathematical resilience have good mathematical proficiency, and students in this category have a good understanding of concepts, where conceptual fluency in solving problems, choosing strategies, and adaptive reasoning are used appropriately. Students have a productive disposition, which can be seen in their being confident in their answers in solving each question. Meanwhile, moderate mathematical resilience has good mathematical proficiency, and students in this category have a good understanding of concepts, strategies, and adaptive reasoning. However, when students' conceptual fluency is in the medium category, failure to solve the problem results in a less productive disposition, productive disposition refers to self-confidence. However, students with low mathematical resilience have good mathematical proficiency, and students in this category have a good understanding of concepts and strategies. During adaptive reasoning and conceptual fluency, students in the low category failed to solve the problem, which resulted in a less productive disposition.

Abstract

Based on a literature review covering the time period 2005-2023, the objective of this article is to present the research trends on the concept of variable and the contributions for its study made through the theoretical framework called Model of the Three Uses of the Variable (Model 3UV). For this reason, a documentary research design was developed with a qualitative approach and at a descriptive level. The instruments for the collection and analysis of information were a search log, a bibliographic matrix, and a synthesis matrix, elaborated in the Excel software. The technique used to carry out the documentary review was the content analysis, from the deductive analytical categories: objective, research method and conclusion. The advanced search was carried out in Academic Google and of the total results obtained, the 10 most relevant articles published during the period 2005-2023 were selected. One of the main findings found was the identification of three trends in research with Model 3UV: the first, related to teaching proposals; the second, concerning the understanding of difficulties in the learning of students; and the third, concerning teaching materials.
