Abstract

Numerical methods are a course that studies mathematical problem solving in a systematic way using numbers. Students still have obstacles in learning numerical methods. These obstacles occur in the mental preparation of students in attending lectures, the lecture process carried out by lecturers and students' academic abilities. The purpose of this study is to describe the creative thinking process of students based on the Wallas stage. The method used is qualitative. respondents are students of prospective mathematics teachers. The data was obtained by testing the ability to think creatively. The test results were analyzed by looking at the creative thinking process according to Wallas, namely preparation, incubation, illumination, and verification. Furthermore, an analysis of test answers and in-depth interviews was carried out based on student learning barriers based on the obstacles faced. Interviews were conducted to students who have high, medium and low learning barriers. In general, students have obstacles in the creative thinking process, namely students only use the method of completion without understanding its meaning. This happens because students do not understand the concept well. As a result, students will not be able to solve problems from the lecturer properly if the form or illustration of the questions is changed.

Abstract

Geometry skills are fundamental in studying mathematics in three dimensions. In schools, it is expected to make schemes of methods and solutions so that students in junior high school can more easily understand geometry lessons by providing tangible examples in students' environments. One of the solution keys to mathematics lessons, especially in geometry, is to combine it with ethnomathematics. In this study, a meta-analysis is reviewed to present an empirical synthesis of studies designed to deliver a systematic design of ethnomathematics related to the meta-analysis's geometric learning education submission, empirical studies are used on the analysis of journal articles from 2015-2021. This research is focused on empirical studies using mixs-methods this meta-analysis conduct to gain knowledge of ethnomathematics on the general effect of students' geometric skills. This method aims to examine and combine all pertinent studies, both published and unpublished, so that a weighted mean effect size would be derived. This meta-analysis aims to review the quantitative results of empirical studies of the effect of ethnomathematics in conveying students' geometric abilities The results of this study are statistically significant with small mean scores on effect sizes and heterogeneity test results between studies. Linear models are used to describe the independent variables that affect all effect sizes. The meta-analysis results were obtained. The effect of ethnomathematics has a positive impact on learning geometry in secondary schools. Ethnomathematics can be used as a solution to learning geometry to improve students' geometry skills.

Abstract

Students need to engage in analytical and logical thought processes, as well as the construction of mathematical knowledge and ideas, to solve problems. What these students are doing is an example of intuitive cognition. From what we can tell, many students, especially those taking Integral Calculus, do not fully use their mental capacities when attempting to solve issues. This research aimed to identify the extent to which intuition is used to solve problems encountered in the study of Integral Calculus. The method of this research was a descriptive qualitative method. A total of 43 participants from the FMIPA UNIMUS Mathematics Education Study Program participated in the study. The study's findings were that the problems persisted regardless of whether the children were high, middle, or poor achievers. The instruments used in this study are the evaluation questions, the intuition surveys, and the interviewing procedures for both the problem solver and the intuitive. They used evaluation tests, observations, and in-depth interviews to triangulate their results. Data analysis entails three stages: data reduction, display, and verification. Affirmatory intuition was most common among students with high problem-solving abilities. In contrast, those with average skills utilized a mix of Affirmatory and Anticipatory intuition. On the other hand, students with limited talents relied on Anticipatory intuition rather than actual intuition. The findings suggest that when presented with a problem, pupils' first instincts are not universal. It indicates that further investigation would develop pupils' innate ability to solve problems creatively.

Abstract

There is a relationship between mathematical problem-solving ability and student self-regulated learning. Data collection using trigonometric comparison math problems and self-regulated learning questionnaires. The subjects in this study were students of class 10th at senior high school 1 Doro. They were taking research subjects based on the category of student self-regulated learning consisting of low, medium, and high levels. Data analysis techniques in this study are data reduction, data presentation, and conclusion drawing. Four indicators of problem-solving ability are used, including understanding the problem, designing problem-solving strategies, performing calculations, and looking back at the problem-solving results. The results indicate that students with a high level of self-regulated learning have problem-solving abilities that tend to be better. Students with high self-regulated learning can meet the indicators of problem-solving ability at the stage of understanding the problem. They are less able at stages to design problem-solving strategies and perform calculations. The finding is that the subject cannot meet the step of looking back on problem-solving. Second, students with moderate self-regulated learning have problem-solving abilities that tend to be quite good. Students in moderate self-regulated learning have not been fully able to meet the indicators of problem-solving ability in understanding the problem. They are unable to complete the other problem-solving stages. Third, students with low levels of self-regulated learning have problem-solving abilities that tend to be less good. Students in this category cannot meet the four indicators of problem-solving ability.

Abstract

Mathematical literacy is logical reasoning in solving mathematical problems. But over time, the meaning of mathematical literacy also develops and is often associated with a person's ability to identify and understand problems in which mathematics plays a role in all areas of life. The purpose of this study is to represent Mathematics Literacy Problems in PISA leveling associated with ethnomathematics and can be used as examples to deliver teaching materials in schools. The research used is a qualitative descriptive study with the object of research is the Culture of the Kutai Society, which is represented in the Mathematical Literacy problem of the PISA Socio-Cultural Context Model. From the research, it was found that the Technique of Designing PISA Model Mathematical Literacy Questions Using the Socio-Cultural Context of the Kutai Community contained 3 things in designing the PISA model grids and math problems based on argumentation indicators. The problem design process is carried out by prototyping using three characteristics, namely content, construct, and language.

Abstract

This study aims to describe the creative thinking process of kinesthetic students in solving arithmetic sequences and series problems with the help of congklak media based on the Wallas stages. The research method used is descriptive qualitative. The subjects of this study consisted of four students of class XI MIPA 5 SMAN 3 Kuningan who were selected using a purposive sampling technique based on the highest kinesthetic learning style questionnaire score. Data was collected through questionnaires, tests, interviews, and observations. The triangulation used is time and technique triangulation. The results showed that: (a) at the preparation stage the four subjects were able to identify problems carefully, completely, and accurately; (b) at the incubation stage, one subject asked the researcher about the concept of an arithmetic sequence, this activity is a stage where the subject looks for a relationship between the concept of an arithmetic sequence and the information contained in the problem so that the subject is able to generate other solutions that are different from what the three thinkers think. another subject; (c) at the illumination stage, the four subjects have a strong will and effort to find alternative solutions to the problems given; and (d) at the verification stage, two subjects were able to get more than one alternative answer idea for each given question, while the other two subjects had not been able to find alternative ideas/other solutions to some of the questions given.
