Prospective mathematics teachers making sense of multiplication algorithm

Abstract

Abstract Multiplication algorithm is broadly used in Indonesian classroom as a technique to multiply two-digits or more numbers. Traditionally, it is introduced as a set of memorized procedures. Hence, despite of its popularity, multiplication algorithm is hardly understood by the students. To understand the root of problem in teaching multiplication, this study aims a t elaborating the abilities of prospective mathematics teachers in making sense the multiplication algorithm. To gather the data, we conducted a survey using written test. The participants were 50 students of mathematics education study program in a state university in Bali, Indonesia. The data were analysed using descriptive quantitative method. From the findings, it is found that 18% of participants were able to explain the logic behind the procedures. Furthermore. the analysis shows the prospective mathematics teachers encountered difficulty in explaining multiplication algorithm due to their inability to making sense the process.
