Mathematical Communication through Problem Based Learning Model using Question Card Media

Abstract

The research objective is to improve mathematical communication skills regarding addition material through the application of the PBL model using question cards as media. This study used a collaborative Classroom Action Research (PTK) method with the Kemmis and Mc. Taggart models, which consists of 4 stages, is planning, action, observation and reflection. The research subjects were the first grade students of SD N Yogyakarta, totaling 29 students. Data collection techniques using observation and tests. Data analysis includes data reduction, data presentation, and conclusions. The results of this study indicate that the use of the PBL model with question card media can improve students mathematical communication skills in the math subject of first grade summation material, evidenced by an increase in the quality of the learning process seen from students who are more active and enthusiastic and an increase in the percentage results of mathematical communication ability tests in cycle I was 58.62% and increased to 86.21% in cycle II.
