THE IMPACT OF DISCOVERY LEARNING ON THE MATHEMATICAL COMMUNICATION ABILITY ON TRIGONOMETRIC MATERIALS

Abstract

Mathematical communication ability in Indonesia are still relatively low due to students'lack of mastery of concepts and lack of teacher attention. This is evidenced by the fact that students cannot capture, master, and explain questions in their own words. The purpose of this study was to determine the effect of the Discovery Learning model on the mathematical communication abilities of class X students in trigonometric material. This research is a quantitativeresearch. This research was conducted on class X students of SMA Negeri 1 Mantup, with a sample of 66 students selected using a purposive sampling technique. Data collection techniques obtained from observation and tests. Data were tested using n-gain, normality test, homogeneity test and hypothesis testing using the t test. The results showed that after being given treatment the average posttest score of the experimental class was higher than that of the control class. In addition, based on the results of the hypothesis test, the value of sig (2-tailed)is less than 0,005 (0,000<0,05) then it is accepted. So it can be concluded that there is a significant influence of the Discovery Learning model on the mathematical communication abilities of class X students in trigonometry material
