Abstract

Numerical literacy ability is currently most highly discussed in education. Numerical literacy ability is the ability that forms the basis for students in solving mathematical problems and is one of the indicators for the Minimum Competency Assessment (AKM). This study analyzes numeracy literacy skills regarding self-efficacy in junior high school students. The research method used in this research is descriptive qualitative. The data was taken using a questionnaire and an essay test instrument. The subjects in the study were students who represented the category of self-efficacy, namely students with low, medium, and high abilities. The results showed that students in the high self-efficacy category met four indicators of numeracy literacy skills, namely, the problem understanding process, the problem modeling process, the process of using concepts in solving problems, and the process of interpreting and evaluating problems. Students with moderate self-efficacy fulfill three indicators of numeracy literacy skills: problem understanding, problem modeling, and the process of using concepts in solving problems. Meanwhile, students with low self-efficacy fulfill one indicator of numeracy literacy ability, namely the process of understanding the problem. Therefore, the results of this study indicate that the better the students' self-efficacy, the better their numeracy literacy skills are.

Abstract

Representations of mathematical concepts are very important in the teaching and learning of mathematics. Visual representations are used to present mathematical concepts to solve, explore or explain the concepts. The purpose of this study was to examine undergraduate mathematics education students' visual representations of multivariable functions using matching items tasks. The study was qualitative research conducted with 10 second-year undergraduate mathematics education students at a University in Zimbabwe. The students matched the functions of several variables which are represented in symbolic and graphic forms. The result showed that most of the students were able to match the functions with their graphical representations. However, most of the students had difficulties in communicating mathematical information and these difficulties emanate from language problems and conceptual understanding.

Abstract

The purpose of this study is to analyze the ability of mathematical understanding in terms of Self-Regulated Learning. This is based on students who have not been able to independently identify, recognize, detail and arrange several questions that will arise in the problem. This research is a qualitative research with a descriptive approach, the subjects in this study were students of class X SMA Negeri in Jakarta. Based on the results of research that has been done, it is stated that students have three categories of Self-Regulated Learning, namely high, medium and low. Each question states an indicator of mathematical understanding ability, but only the high Self-Regulated Learning category fulfills all indicators of mathematical understanding ability. Because subjects with high Self-Regulated Learning category can understand all the questions that have been asked. Meanwhile, for students in the moderate Self-Regulated Learning category, they fulfill two indicators, namely; (1) students can define a concept in writing, (2) students can present a concept in a problem and turn it into another form of expression. For the low Self-Regulated Learning category, students do not meet two indicators of mathematical understanding ability, only meet one indicator, namely; can identify problems and determine the outcome of a problem.

Abstract

This study aims to describe the high school mathematics teachers' conceptions of creative thinking. The research approach used is descriptive qualitative. The subject in this study was a high school mathematics teacher in Yogyakarta. This study uses the results of an open questionnaire as the main data and interviews as supporting data. The results of the study show that the mathematics teachers' conceptions of creative thinking are limited to ways of thinking/solving a problem by using new steps or ideas so as to find/produce something new/different from usual. Creative mathematics teachers are described as being able to come up with new ideas, being able to make new innovations in learning. The teacher plays an active role in guiding students to be able to think creatively by giving questions or assignments that trigger mathematics in the form of descriptions (open questions) so that students can explore their abilities to trigger their creative thinking. The teacher assesses the ability to think creatively by giving open questions/trigger assignments and then analyzing the steps/results of the work to find new steps/ideas in the process.
