Abstract

The process of thinking in formulating a mathematical model requires cognitive processes. In learning mathematics, one of the factors that influence mathematics ability is gender differences.  This research explores and provides an overview of the cognitive processes, especially using the representational form in mathematical modeling regarding gender differences. The type of research used is descriptive exploratory with a qualitative approach. The research subjects were 36 pre-service teachers in the mathematics education study program, consists of 18 males and 18 females. The instruments were a written test and an interview guide sheet. The result shows that males get higher percentages than females to answer the representational problem correctly. In conclusion, both males and females solve the graph problem using representative form through three components of the cognitive process.  The first and second component, namely knowing and applying, shows the same behavior: retrieving the information from the mathematical problem and displaying the information into the graph. For the third component, reasoning also offers the same behavior because the truth of the graph that justifies refers to the mathematical properties. The study implies that it might be the same treatment for males and females to improve representational form regarding the components of cognitive process, namely, knowing, applying, and reasoning.

Abstract

This research aimed to identify students' mathematical thinking style in mathematics education to resolve the higher-order thinking problem. The type of study was descriptive using qualitative data based on the vector analysis test. The vector analysis was identified by mathematical thinking style that divided into visual, analytic, and integration. This thinking style formed the qualitative data in the form of a description of the suitability of the student answer using indicators of any mathematical thinking styles. The subject whom students in the course of Vector Analysis Fourth Semester was interviewed after got mathematical thinking style data. The results showed that a lot of students has mathematical integration, that is, both visually and analytic. Students who have mathematical thinking style visually answered the question using a sketch of parallel vectors, perpendicular vectors, vector tangent, but they do not put the vector notation. Students who have analytical thinking styles differentiated vectors relationship using the verbal description of the appropriate definition that has been studied when they were in high school level. Students who have integrated mathematical thinking styles draw vectors using vector notation and explain verbally.

Abstract

This study aims to determine whether students' mathematical creative thinking skills that are taught with a quantum learning model based on contextual problems are better than mathematical creative thinking abilities that are taught with conventional learning. The population of the study was students of class XII MIPA SMA 2 Singaraja in the first semester of 2018/2019 academic year. The research sample was determined by cluster random sampling technique. This research was categorized as quasi-experimental research with post-test only control-group design research design. Data about the ability of students' creative thinking skills were collected through tests of students' mathematical creative thinking skills. Furthermore, the test scores of the ability to think mathematically creative were analyzed using the t-test of one tail (right tail) at a significance level of 5%. The results of the analysis show that tcount = 1.80295 while the significance level of 5% is obtained ttable = 1.66864, so H0 is rejected. This statistical value means that students' mathematical creative thinking skills that are taught with contextual problem-based quantum learning models are better than students' creative thinking abilities that are taught with conventional learning. It can be concluded that the application of learning with contextual problem-based quantum learning models provides a positive influence on students' mathematical creative thinking skills.

Abstract

This study aims to use the Pendidikan Matematika Realistik Indonesia (PMRI) approach to measure the mathematical reasoning ability of grade VII students in answering PISA-like mathematics problems on number content in the context of COVID-19. This study employs descriptive research with 34 participants from a junior high school in Palembang, Indonesia. Tests, interviews, and observations were utilized to collect data. The method of analysis adopted is descriptive. Google Meet is used to facilitate learning. Learning the PMRI technique was accomplished in this study by assigning sharing and jumping tasks. That is, assignments for students to discuss with each other have different levels of difficulty, followed by two exam questions. In the context of COVID-19, the test questions are PISA-like maths problems. The results show that students’ average mathematical reasoning skill is 63,037, with mathematical manipulation a common indicator. Most students have exhibited indications for presenting conjectures. However, only a few students have put down indicators for drawing logical conclusions, so drawing logical conclusions is an indicator that students rarely see. Overall, grade VII students' mathematical reasoning skills in answering PISA-like mathematics questions on number material in the context of COVID-19 utilizing the PMRI approach is good since students are used to modeling contextual problems such that mathematical manipulation indicators occur.

Abstract

The test is a tool to collect information about the achievement of learning objectives so that the test must have good quality in order to be able to measure students' abilities accurately. To determine the quality of the test, it is necessary to do an analysis, one of which is the Rasch model approach. This study aims to analyze the quality of the final semester test results in learning mathematics—sampling using a purposive sampling technique. The subjects of this study were 56 students of Junior High School (SMP) in Yogyakarta, consisting of 25 males and 31 females. The test instrument consists of 40 multiple choice questions with the correct answer given a score of 1 and the wrong answer being given a score of 0. Therefore, the data obtained is dichotomous. The test kits were analyzed by applying the Rasch model. The study results obtained an estimate of the validity of item fit, where the questions analyzed had an INFIT MNSQ value between 0.94 - 1.11 and all questions with an OUTFIT value t ≤ 2.00; thus, 40 items fit according to the Rasch model. The characteristics of the test questions based on the Rasch model have a very difficult difficulty level of 0 items by 0%. The difficult category is three items at 7,5%, the medium category is 20 items at 50%, the easy category is 17 items at 42.5%, and 0% for the very easy category. The reliability of the case estimate value is 0.00 in the medium category, and the reliability of the item estimate value is 0.85 in the very high category. The implication of this research is additional knowledge regarding the Rasch analysis of mathematical problem models as a graduation standard.

Abstract

The teacher’s attitude towards mathematics teaching is seen as an essential factor in forming students’ attitudes towards mathematics. However, no one has extensively described the reflection of teachers’ self-confidence in teaching mathematics, especially for novice primary teachers. Therefore, the purpose of this study sought to describe a reflection of the self-confidence attitude of novice primary teachers in teaching mathematics. A questionnaire based on novice primary teachers’ teaching experience was administered to a total of 28 novice primary teachers (N = 22 males, N = 6 females) conveniently selected to participate in the study reported in this article. The semi-structured interviews data explored novice primary teachers’ reflections on the given questionnaire scale items. The qualitative data obtained from semi-structured interviews informed the quantitative information extracted from the questionnaires. The results showed that the reflection of the self-confidence attitude of novice primary teachers in low, moderate, and high participants on the scale of confidence in teaching mathematics raises three essential findings, specifically (1) ability on content knowledge, (2) ability to explain, and (3) ability in classroom management. The resulting reflection in low, moderate, and high participants on the scale was an attitude toward success in teaching mathematics, namely, the appraisal of others, and on the scale, the usefulness of mathematics teaching, namely the ability to understand the usefulness of mathematics.
