Abstract

Spatial ability is an important one of the abilities for completing many tasks in everyday life successfully. Spatial ability is considered a type of different ability to others. Therefore, there needs a study on how are the characteristics of spatial abilities and to develop in schools. This paper is to reveal the ways are developing spatial abilities in learning mathematics. Based on literature review from some research, at least that there are six ways to develop spatial abilities in learning mathematics, namely: (1) using spatial language in daily interactions; (2) teaching for sketching and drawing; (3) using a suitable game; (4) using a tangram; (5) using video games; and (6) origami and folding paper. Playing video games like Tetris are exercises for spatial relations, mental rotation, spatial orientation, and spatial visualization.

Abstract

After confirming the positive case on March 2, 2020, online learning and distance learning is one of the alternatives for learning that is carried out in Indonesia. Apart from the advantages and disadvantages, this learning is an alternative so that learning continues during the COVID-19 pandemic. In connection with this condition, research in the field of education must also adapt to several new phenomena such as limited face-to-face learning, so researchers need to think about research designs that are relevant to the conditions of the COVID-19 pandemic. Single subject research or often referred to as Single Case Experiment Design is one of the alternative research methods that can be carried out during the COVID-19 pandemic, where one of the characteristics of this research is to focus on one subject, so there is no need to use relatively large subjects to conduct experiments.

Abstract

The deductive structure is fundamental in mathematics, but students often struggle to derive logical consequences when constructing proofs or engaging in the bridging process. This study analyzed students’ ability to deduce logical relationships between properties in geometric thinking on quadratic functions. The participants were students (N=139) from the mathematics education program. The properties of quadratic functions and their interrelationships contained in the premises represented students’ responses to the instrument. The responses were dichotomously coded based on the criteria of the carried-out deduction process and then evaluated using Rasch analysis. The findings revealed that, in general, the distribution of students’ ability levels was below most levels of the carried-out deduction process. Although a group of students had already reached the high-ability category, the overall distribution was still dominated by low-ability levels. Many students continued to face serious challenges in reaching the final stage of the deduction process—advanced premise integration and deductive synthesis—since most of them established relationships among properties merely from the given information. There were indications that learning experiences during higher education contributed positively to the improvement of students’ ability at the deduction level. The study recommends four steps to habituate students to the process of deduction.
