Students’ Mathematisation in Solving Mathematical Literacy Problems with Space and Shape Contents

Abstract

This paper aimed to describe four undergraduate students’ mathematisation from Surabaya and Sidoarjo in solving mathematical literacy problems with space and shape contents. This study used descriptive research with a qualitative approach. Data were collected by giving the mathematical literacy problem with space and shape contents and interviews. Next, data were analysed by studying the four mathematisation processes: formulating, using, interpreting, and evaluating. The results of this study pointed out that students” mathematisation in solving mathematical literacy problems with space and shape contents were as follows 1) formulating contextual problems into mathematical problems by verbally describing, using mathematical symbols that have been understood, and using appropriate modelling, 2) building or using direct mathematical objects (facts, concepts, principles, and procedures) and indirect (mathematical reasoning) to obtain mathematical solutions, 3) summarising the results obtained from the counting operations that have been performed, and the last 4)stating that the mathematical solution obtained is correct by raising logical reasons. Students’ mathematisation was a principal process in solving mathematical literacy problem with space and shape contents, so it was important to emerge students’ mathematisation in the mathematical classroom or daily activities.
