Abstract

Abstract: The background of this research was the low ability of students mathematical understanding which effect to the lower score of mathematics learning outcomes in junior high school. The type of this research is experimental research and using the static group comparison design. The population in this research were all grade IX students of SMP Negeri 1 Kampar Timur. The sample in this research consists of two class, where the IX1 as an experimental class and the IX2 as a control class. The aim in this research was to know the effect of implementation discovery learning model toward students mathematical understanding ability based on KD 3.7 Create the generalization of the surface area and the volume of curved side geometry (tube, cone, and ball), and KD 4.7 Complete the contextual problems which are related to the surface area and the volume of curved side geometry (tube, cone, and ball), and also the combination of some of the curved side geometries. The instruments in this research were mathematical early ability test and the mathematical understanding ability test (postest). The result of mathematical early ability test was used for determining the sample of class. The postest result was analyzed by nonparametric statistic test of Mann Whitney and the magnitude of the effect was calculated using the Cohen’s formula. The result of the research showed that implementation discovery learning model gave the positive effect toward the mathematical understanding ability. The implementation discovery learning model had a magnitude of the effect for 76% toward the students mathematical understanding ability at grade IX of SMP Negeri 1 Kampar Timur and included in the medium category.Key Words: Discovery Learning, Mathematical Understanding Ability.

Abstract

Abstract: This research is classroom action research that aims to improve learning process and to increase mathematics achievement with applied the learning cooperative approach Think Pair Square (TPS) model. The research consist of two cycles, each cycle has four stages, which are planning, implementation, observation, and reflection.The subject of this research is student of class VIII6 SMPN 4 Siak Hulu in academic years 2017/2018, which amounted to 40 students, consist of 19 boys and 21 girls. The instruments of data collection in this research were observation sheets and students Mathematic tests. The observation sheets were analyzed in qualitative desciptive, while the students’ Mathematic tests were analyzed in quantitative descriptive. The qualitative descriptive showed an improvement of learning process prior to the action on the first and second cycle. Most of students were very confidenced and actived in learning process, such as while they were finished mathemathic’s problems that given, presenting the result of problems and giving the conclusion of learning. Number of students that reach Minimum Mastery Criteria increase from basic score to first test I and II. The results of this research showed an increasing number of students learning mathematicsabout knowledge of the basic score (42,5%)to the first test (62,5%) to the second test II (80%). For the skills of basic score the first test (72,5%) to the second test (95%), Results of this research indicates that appication of the learning cooperative approach Think Pair Square (TPS) model can improve learning process and increase mathematics achievement from the students at class VIII6 SMPN 4 Siak Hulu in academic years 2017/2018 for the subject matter relations and functions.Key Words: Mathematics Achievement, Learning Cooprative Approach ThinkPair Square (TPS)
