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

Learning mathematics has a significant contribution to the students’ daily activities, one of which is on social arithmetic topic. The implementation of social arithmetic, in general, is mostly found in buying-selling and banking activities. However, students still find difficulties in understanding this topic. It is because the teaching and learning activities still use a conventional approach, which restricts the students to imagine how it is implemented in daily life. Therefore, this paper aims to describe the innovative learning activities of social arithmetic among junior high school students using the Realistic Mathematics Education (RME) approach. This research was conducted in three meetings, and the researcher acted as the teacher in the class. The results showed that the innovative learning of social arithmetic using the RME approach and word problems could improve the students’ learning outcomes with an average score of 81.92% and 92.59% of the total of students scored above passing grade.

Abstract

Mathematisation ability of prospective teachers that was low in solving mathematical literacy problems needs serious attention. Therefore, to help prospective teachers do mathematization, they were employed by giving mathematical literacy problems. This study aims to produce mathematical literacy problems that were valid, practical, and have potential effects on the mathematization ability of prospective teacher students. The study was conducted using a design research type development study. Thirty students of prospective teachers in a private university in Sidoarjo became the subjects. Mathematical literacy problems’ qualities from this research should support prospective mathematics teachers in categorizing horizontal and verticalization activities. In addition, the problems were designed using the Program for International Student Assessment (PISA) framework with the Indonesian context. The results suggested that the developed mathematical literacy problems could be categorized valid based on validators’ evaluation, practically based on the small group phase results, and have the potential effects were assessed from the results of student tests handed in field test phase using mathematical literacy problems. The test results showed that 78% of prospective mathematics teachers were in the good category of mathematization ability after using the developed problems. The developed mathematical literacy problem has a potential effect so that it can be used as an alternative question in lecturing higher education activities to support the mathematics of prospective teacher students.
