Analysis of Mathematical Communication Ability Third Grade Elementary School Student on The Material to Know the Concept of Fractions

Abstract

This research is based on the results of preliminary field studies on students’ mathematical communication abilities on fractions concept that have not been considered to be developed. The ability of communication is an ability to convey various mathematical concepts of ideas, symbols, formulas both orally and in writing in order to be understood by others. This mathematical communication is one of the demands contained in the mathematics learning curriculum in elementary school third grade. Therefore, it needs to be analyzed how third grade students ability of mathematical communication on material knowing the fractions concept. Method used in this study is descriptive qualitative method To provide an overview of students’ mathematical communication skills and make conclusions about the underway phenomenon or conditions. Data collection techniques such as observation, interview and documentation study. Data analysis technique is content analysis with research focus on the whole contents of communication either expressed or implied. The results showed that the communication ability of third grade students of elementary school on the material knowing the concept of fractions is still lacking. This is indicated by the five indicators studied, only three indicators appear. The most common indicator is showing the fractions by draw the fraction into picture and reading the fractional numbers that show on picture. While the indicator that does’nt appear is explaining fractions using real objects, declaring the concept of fractions in everyday events in mathematical ideas, and revealing the concept of fractions using their own language orally and in writing.
