Abstract

The ability of mathematical connections possessed by students can be seen from the ability of students to compile math problems. This study aims to determine the type of mathematical connection made by elementary school students in problem-posing activities. The research was conducted using a qualitative descriptive method. The participants were 34 fifth grade students (male =16 female =18) of one of the public elementary schools in Mataram, West Nusa Tenggara. Data were collected from the results of student work and interviews. The analysis was carried out qualitatively according to the indicators of the complexity of the problem through problem posing learning. The results showed that there were four types of mathematical problems and their relatedness that occurred in student problem-posing activities, including (1) unsolvable math problems, (2) incorrectly solved math problems, (3) neglected math problems contextual information, and (4) mathematical problems that have complexity and relevance. Based on these results, it can be recommended for further research to determine strategies to improve students' mathematical connections in problem-posing activities.

Abstract

One of the competencies for mathematics teachers that needs to be developed continuously is professional competence. However, even if efforts for developing teachers’ competencies have been made formally by the government, it seems still lacking. This study, therefore, aims to develop mathematics teacher professional competencies through an informal development model using social media. This research used a qualitative method, a case study design, involving 19 mathematics teachers from various regions in Indonesia in the informal development process in the range of 2019-2021. The informal approach was carried out using question-and-answer techniques and guided discussions on mathematical problems. From the teacher development processes, 30 mathematics problems and their solutions were collected. As an illustration of this development process, this article presents five problems and their solutions, including solutions for two mathematics problems on conceptual understanding and three mathematics problems on problem-solving. We conclude that this informal approach is fruitful in helping mathematics teachers solve mathematics problems. This study implies that the teacher development process carried out in this study can be used as a model for informal teacher development by other higher education academics in their respective places.

Abstract

Research on developing a mathematical reflective thinking test instrument for prospective mathematics teachers using the Rasch model is limited. This study aims to develop a reflective thinking ability test for prospective mathematics teachers using the Rasch model. The development steps consist of preparing a blueprint, writing items, reviewing items, conducting trials, analyzing test results, and revising. The test developed is a description test validated by five experts, consisting of two expert professors in evaluating mathematical ability, one expert lecturer in mathematical ability, and two expert lecturers in group theory. The test was also piloted on 26 students. The study's results using the Rasch model analysis showed that this instrument was "very reliable," and 12 of the 13 test items were "valid." The instrument has fulfilled all the stages of instrument development and was declared valid and reliable; thus, this test can be used to examine prospective mathematics teachers’ mathematical reflective thinking ability.

Abstract

In cultural anthropology, people have recognized various mathematical activities, such as counting, calculating, measuring, and weighting, with different terms derived from each culture. Community activities in responding to the existence of their environment will give rise to mathematics as part of problem-solving, including finding characters or features of residence to build. Therefore, this study explores mathematical forms in the measurement of residential characters based on sikut awak that can be used in mathematics learning. This research is an ethnographic study. Data were collected from various literature studies, field observations, and interviews. Informants included in the study were two cultural experts, one Adat leader, and one traditional builder who knows sikut awak’s measurement format in determining the traditional residential characters of Sasak people. This study shows that the determination of residential characters uses mathematical models in its calculation.
