Abstract

Spatial ability is one of the essential abilities to be mastered by students, especially in geometry. There is not much research, especially in Indonesian, that examines students' spatial abilities and their relation to Descriptive Geometry. This study aims to analyze students' misconceptions in the Descriptive Geometry course and describe the profile of students' spatial abilities in online learning during the COVID-19 pandemic. This study's subjects from the Mathematics Education Department of Universitas Negeri Jakarta. This research is descriptive qualitative. The learning was carried out in 16 meetings with three initial meetings offline, and the next 13 meetings online. The test was given twice at the 8th and 16th meetings accompanied by interviews with students who made mistakes in taking the test. The test results showed that students who made mistakes did not have the ability to spatial perception, spatial relation, and spatial orientation. However, there was a case of students who made mistakes still having the ability to spatial perception, spatial relation, and spatial orientation. The obstacles that affect students' spatial abilities are online learning that is not supported by technical matters, namely: limited internet networks and internet quota availability.

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

Continuous treatment is needed in developing mathematical dispositions. Even at the higher education level, some prospective teachers still need proper treatment in developing their mathematical dispositions. This study tries to reveal instructors' role in fostering their students' mathematical disposition to better didactical situations. This study is qualitative research with a content analysis approach. The results obtained in this study indicate that the instructor's role is still needed in the classroom regardless of the students' mathematical disposition. Instructors ' expected learning role becomes diverse based on the mathematical disposition grouping between good, moderate, and less mathematical dispositions. For prospective teachers who have an excellent mathematical disposition, the instructor's role is to confirm a theorem, confirm answers to questions, and the benefits of contextual topics. For prospective teachers who have a satisfactory mathematical disposition, the instructor's role is to motivate, direct the learning, and keep the classroom conductivity. Whereas for prospective teachers deficient in mathematical disposition, the instructor's role is needed as a direct learning source, structured learning director, and an enjoyable learning rhythm.

Abstract

Argumentation as an aspect of problem-solving has been studied in mathematics education. However, mathematical proof still needs to be resolved further. This study investigates students' mathematical argumentation skills when proving mathematical statements based on their self-efficacy. The research subjects were 43 mathematics education students at a university in Aceh Province who had taken a number theory course. The study used a qualitative approach with a case study design: students’ mathematical proving self-efficacy. Data was obtained using self-efficacy questionnaires and mathematical proof test instruments that experts have validated, while the data triangulation used was an in-depth interview. The results of this study reveal that students' mathematical argumentation skills in proving mathematical statements have differences based on their self-efficacy. The mathematical argumentation ability of students with high self-efficacy involves all aspects of argumentation well so that the construction of the proof is scientifically correct. Meanwhile, the argumentation ability of students with moderate or low self-efficacy still does not involve essential aspects of argumentation. So, the proof results are not scientifically correct because they have not arrived at the proper conclusion.
