Abstract

Fraction division is one of the most difficult subjects in elementary school. Not only elementary students but many prospective teachers don’t understand the fraction division concept yet—most of them using a keep-change-flip algorithm to solve fraction division problems. A study using rectangle representation was conducted by us to prospective teachers. This study aims to see whether this rectangle representation will make prospective teachers understand or not. To do so, we made a mixed-method study with 80 prospective teachers as participants. The results show that 53,75% of prospective teachers use the keep-change-flip algorithm without understanding the concept of fraction division, and just 15% of prospective teachers understand fraction division. We assume that most prospective teachers still can’t imagine how fraction division works in a real-life context. They remember what they used to do to finish the fraction division problem that their teacher has introduced in primary school. Based on the results, we conclude that the study with rectangle representation still needs an improvement, whether the teacher’s explanation or the rectangle media.

Abstract

Mathematical communication skills are essential for prospective elementary school teachers. However, many problems still occur in prospective elementary school teachers related to their mathematical communication skills. This study aims to describe the mathematical communication skills of prospective elementary school teachers and their level of self-regulated learning. This qualitative research, employing a phenomenological design, aims to explore and identify the mathematical communication skills of prospective elementary school teachers. Forty-eight prospective elementary school teachers participated in this study, and nine were selected for in-depth interviews to understand their mathematical communication skills better. The results showed that prospective elementary school teachers with high self-regulated learning almost met all indicators, prospective teachers with moderate self-regulated learning met three indicators, and prospective teachers with low self-regulated learning met one indicator. All of them were unable to provide mathematical solutions with rational reasons. Several factors cause prospective elementary school teachers not to have good mathematical communication skills, such as 1) lack of knowledge of basic geometry concepts, 2) lack of motivation to learn independently, 3) inability to manage what to learn, and 4) inability to evaluate their mistakes. Based on the research results, not all prospective elementary school teachers possess practical communication skills.
