Abstract: This research is a pre-experimental research with the static groupcomparison study design, that aims to determine whether the application of problemsolvingstrategy in mathematics learning positively affect on mathematical problemsolving ability of students of class VIII SMP Al-Azhar Syifa Budi Pekanbaru school year2015/2016. This research involved experimental and control classes that consists of 24students and 20 students. The test score of students’s mathematical problem solvingability is the data that used to test hypothesis of the research. Based on the test score,obtained the average value of mathematical problem solving ability of students inexperimental class was 3,40 and the average value of mathematical problem solvingability of students in control class was 2,16. From the Mann-Withney test, obtained thesignificance is 0,001 (less than ߙ = 0,05), it is mean that ܪ଴ has rejected and ܪଵ hasaccepted. The average value of test mathematical problem solving ability of students inexperimental class is higher than the average value of test mathematical problemsolving ability of students in control class, it can be conclude that the application ofproblem-solving strategy in mathematics learning positively affects the mathematicalproblem solving ability of students of class VIII SMP Al-Azhar Syifa Budi Pekanbaruschool year 2015/2016.Keywords: Problem-Solving Strategy, Mathematical Problem Solving Ability, Pre-experimentalResearch2

Abstract: This research was classroom action research that aims to improve learning process and to increase learning result in mathematics with applied the learning strategy of reciprocal teaching. The subject of this research was student of class VII1 SMPN 25 Pekanbaru in academic years 2017/2018, which amounted to 34 students, consist of 9 boys and 25 girls. The research consist of two cycles, each cycle has four stages, which are planning, implementation, observation, and reflection. 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. The results of this study indicate the number of students who reached Minimum Mastery Criteria of knowledge increase from basic score to UH-I and UH-II. The results of this research showed an increasing number of students learning mathematics about knowledge of the basic score (47,06%) to the first UH-I (61,76%) to the UH-II (76,47%) thus it can be concluded that the application of reciprocal teaching strategy can improve learning process and increase mathematics achievement from the students at class VII1 SMPN 25 in academic years 2017/2018 for the social arithmetic.Key Words: Students’ Mathematic Achievement, Reciprocal Teaching, Class Action Research

Abstract: This research was using class action research. This research aims to fixed the process of learning and improve learning result in mathematics in grade XI MIA 5 of MAN 2 Model Pekanbaru by applying the Discovery Learning model. The subject of this research were the students in the class XI MIA 5 of MAN 2 Model Pekanbaru that consist of 10 boys and 16 girls at the second semester of academic year 2016/2017. During the learning process, there is a problem of learning that is still focused on the teacher so that students can not find the concept of learning. To solve this problem requires a learning model where students can actively discover their own learning concepts. The instruments of data collection in this research were observation sheets and students mathematics tests. The observation sheets were analyzed in desciptive narative, meanwhile the students’ mathematic tests were analyzed in statistic desciptive. Based on the analysis showed that an improvement of learning process prior to the action on the first and second cycles and improve the students’ in the second semester academic years 2016/2017. Based on the result of research, the implementation of discovery learning methods can fix the learning process and improving student’s achievement of learning mathematisc in grade XI MIA 5 of MAN 2 Model Pekanbaru.Keywords : Students’ Math Achievement, Discovery Learning Model, Clasroom Action Research.
