Description

There is a perception about calculator use within the school mathematics setting in that it has no purpose aside as a computing tool and can have a negative impact on the students’ mathematics ability, especially in the lower educational stages. In Indonesia, using calculators in the classroom is frowned upon and it is prohibited in the examination. In this study, we attempted to answer this issue by investigating the impact of calculators on the students’ critical thinking. Through design research, we developed mathematics learning materials involving calculators for 4th-grade students. The implementation of the learning materials was conducted in nine schools in Yogyakarta. The data collected in the form of video recording was then analysed according to the critical thinking framework. This paper reports the results from the first cycle of this study. The result is expected to contribute to the mathematics education literature and help to rectify the negative perception of the use of calculators in primary school mathematics.
