Probing-Prompting Based On Ethnomathematics Learning Model: The Effect On Mathematical Communication Skill

Abstract

Communication skills on mathematics should be mastered by students to involve in mathematics learning process. This study aims to determine the effect of the Probing-Prompting based on Ethnomatematics learning model on the impact on mathematical communication skills. This research is an experimental with simple random sampling technique. The instrument used to collect data is a test of mathematical communication skills. Test trials include content validity, level of difficulty, difference in power, and reliability. For the normality test using the Liliefors-test, the homogeneity test uses a similarity test of two variances. The hypothesis test used by t-test. The results show that there is an influence from the Probing-Prompting based on Ethnomatematics learning model on mathematical communication skills.
