Abstract

This research aims to determine the improvement of Mathematics calculation skills by implementing STAD learning assisted by PANAMA media (Mathematics Napier Board). This research is Classroom Action Research (PTK) with the research subjects being 27 class IV students at SD Negeri Depok 1, Sleman. The object of this research is mathematical calculation skills in the arithmetic operations of multiplication and division. The instrument used in this research was test questions supported by observation sheets. The results of the research at the pre-cycle stage showed a class average of 68.07 with the number of students completing only 10 students or 37.0%. These results increased significantly after taking action in cycle I with a class average of 81.18 and in cycle II the class average was 90.59. In cycles I and II, it was seen that there was an increase in Mathematics calculation skills by 22.2% with the number of students who achieved KKTP at the end of cycle II being 23 students or 85.1%. Based on these results, it can be concluded that the application of STAD learning assisted by PANAMA media) can improve calculation skills, especially in the calculation operations of multiplication and division.

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

The purpose of this study was to see whether the situation-based learning model can increase students' learning independence and ability to solve mathematical problems in class VIIA SMP Negeri 8 Pontianak. This study used an experimental method with a sample of 31 students. The instruments used in this study were questionnaires and tests. The data analysis technique used was hypothetical statistical test, t test, and product moment test. Based on the analysis, it is concluded that: 1) students' learning independence is in the high category (94%), 2) in the t-test the results obtained t_hitung ≥ t_tabel or 1.871 ≥ 1.697 in accordance with the testing criteria, the situation-based learning model affects the ability to solve math problems, 3) there is no significant relationship between learning independence and the ability to solve math problems. Therefore, the application of the situation-based learning model has a positive influence on learning independence and the ability to solve math problems of students in class VII SMP Negeri 8 Pontianak.

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.

Abstract

The aim of this research is to analyze the visual reasoning abilities of high school students based on gender using trigonometry comparison material. The subject consists of two students with the provisions of one male student and one female student. Data was collected by administering a visual reasoning test to 10 10th grade students, then the selected subjects were interviewed. The data validation used is the triangulation method. Data analysis techniques use data reduction, data presentation and conclusion drawing. The results of the research showed that male students in the trigonometry comparison material were able to identify side sides, slanted sides, front sides, and were able to determine the use of the cos and tan formulas to solve problems with correct calculations. Meanwhile, female students in the trigonometry comparison material were able to identify side sides, slanted sides, front sides, were able to determine the use of the cos and tan formulas, but were less precise in determining the value of cos 30°, and less precise in making the final decision because they did not convert it into units. the same thing, namely meters.

Abstract

The failure of students to solve matrix problems may be due to misconceptions in their concept image. Concept image encompasses cognition related to a concept, including mental representation, properties, characteristics, and cognitive processes associated with that concept. This study aims to understand students' concept image regarding matrices. The method used is qualitative with a phenomenological approach, conducted on 19 eleventh-grade students in a madrasah located in Narmada District. Data collection involves tests and interviews. Samples are selected through testing. Concept image is determined based on indicators, including aspects of mental representation, processes, and properties. The research findings reveal that Subject 1 has a strong concept image, demonstrated by their ability to relate matrix concepts to relevant contexts, internalize concepts well, and apply them in various situations. Conversely, Subject 2 has a weak concept image, struggling to form a clear mental representation of matrix concepts and facing difficulties in applying correct formulas and procedures. Therefore, it is essential to implement teaching approaches focusing on deep conceptual understanding and fostering a strong concept image to enhance student comprehension.
