Analysis of students Initial mathematical communication skills in mathematics learning

Abstract

This research is motivated by the low ability of students to communicate mathematical ideas, compile mathematical evidence using complete sentences, symbols, tables, and diagrams, to clarify the existing problems. This study aims to find out how the initial mathematical communication skills of students in learning mathematics, namely by giving mathematical problems related to the daily lives of students of grade VIII SMP. Problems are constructed based on indicators of communication ability and then assessed using the scoring rubric mathematical communication skills. The instrument used in the form of a preliminary test with 2 item and a sample of as many as 21 students. The results of the scoring rubric of students’ mathematical communication skills obtained in indicator 1 were 23.81%, indicator 2 was 28.57%, indicator 3 was 38.11% and indicator 4 was 14.28%. If seen from the overall results of the initial test students only get 14.28% who is able to explain with the idea of dramatic communication. The results of this initial test study was 42.85%. It indicate the need for follow-up to improve students’ communication skills.
