Improving Mathematic Students’ Learning Process and Achievement Through Discovery Learning Model at MAN 2 Model Pekanbaru

This classroom action research is aimed to improve teaching learning process and students’ achievement by applying Discovery Learning model. The subject of this research was the second semester mathematic students of tenth grade science class in MAN 2 Model Pekanbaru year 2016/2017 which consisted of 13 male students and 17 female students. There were two types of instruments used in this research namely observation sheets to record the teaching learning process and students’ achievement test to obtain students’ score achievement. From the observation sheets which were analyzed descriptively narratively and the second instrument which were analyzed descriptively statistically, it was found that there was a significant improvement in the teaching learning process and the number of students who reached the minimum passing grade increased before the treatment was carried out towards the Cycle I and Cycle II. In the regard of knowledge competence, there were only 11 students or 36,67% who reached the minimum passing grade before the treatment, became 15 students or 50% at the first cycle and 21 students or 70% at the second cycle. In the regard of skill competence, the number of students who reached minimum passing grade from the first cycle with a percentage of 23.33% was increased to 50% in the second cycle. According to the finding of this research, it can be concluded that the implementation of Discovery Learning (DL) model successfully improved the mathematic of second semester students of tenth grade science class in MAN 2 Model Pekanbaru year 2016/2017.
