Abstract: This research is classroom action research that aims to improve the students mathematics achievement by implementing the cooperative learning type STAD. The subject of this research was the third grade students at class III SDN 01 Pendalian IV Koto in the second semester academic years 2014/2015. There were 20 students which consist of 11 boys and 9 girls who have heterogeneous academic ability. This research was implemented in two cycles, and at the end of every cycle carried out mathematics achievement test. Data collected through observation and mathematics achievement test. The results of this research showed that the activities of teacher and students have done well after doing the action. The students learning process have more focussed on increasing the knowledge and students interaction become better. Most of students were excited and more active in learning process, such as while they were doing the steps of learning, like preresenting students’ worksheet or questions, respond to their friend’s presentation and giving the conclusion of learning. The action was successful if the number of students who got the score of minimum mastery criteria increase in mathematics achievement tests I and II. The number of students who got the base of score of minimum mastery criteria on the first mathematics achievement test I (first cycle) and the second mathematics achievement test II (second cycle) are respectively 25%, 45%, and 60%. The results of this research indicates that the cooperative learning type STAD can improve the mathematics achievement of the third grade students at class III SDN 01 Pendalian IV Koto.Keywords: Mathematics Achievement, Cooperative Learning Type of STAD, Class Action Research

Abstract

Lack of concept mastery is thought to be one of the causes of students difficulties in learning mathematics. Moreover, a learning management unsuitablewith the level of students’intellectual development and the low active role of students in learning is seen as a trigger for a tenuous control of concepts.This condition underlies the importance of a research, so the goal is to examine the impact of the application of ExampleNon Example learning models, guided by Bruners Theory. This study employs the design of pre-test and post-test Group Design with a sample of 199 people. Research data were collected by tests and analyzed descriptively and inferentially. The results show that the application of the Examples Non Examples model based on Bruner’s theory contributes significantly to improve students understanding ofthe concept of plane figure by 47.8%.

Abstract: This research is a classroom action research that aims to improve the learning process and improve the learning outcomes of mathematics by applying the Problem Based Learning (PBL) model. The subjects of this study were students of class VIII-8 of SMP Negeri 20 Pekanbaru in 2018/2019 academic year, totaling 42 people with heterogeneous levels of academic ability. This study consists of two cycles and each cycle consists of the stages of planning, implementation, observation and reflection. Every end of the cycle is held Daily Deuteronomy (UH). Data collection is done through UH observations and tests. Data analysis was carried out by descriptive narrative analysis and descriptive statistical analysis. Actions are said to be successful if there is an improvement in the learning process and the number of students who achieve the Minimum Completion Criteria (KKM) increases in UH I and UH II. The results of the study showed an increase in the activities of teachers and students. Most students are seen as actively participating in the learning process, such as discussing, presenting Student Worksheets (LKPD), responding to their friends' presentations and giving learning conclusions. Students also try to solve the problems that the teacher gives them well. Therefore it can be said that there is an improvement in the learning process in the cycle. In addition, the number of students who reached KKM on the basic score, UH I (cycle I), UH II (cycle II) were 15 people (35.71%), 23 people (54.76%), and 33 people (78.57%) respectively. . The percentage of KKM achievement shows an increase from before the action to after the action so that it can be said that the learning outcomes of students also increase. The results of this study indicate that the PBL model can improve the learning process and improve the mathematics learning outcomes of students of class VIII-8 in SMP Negeri 20 Pekanbaru in the odd semester of the 2018/2019 academic year on material relations and functions.Key Words: Mathematic learning evaluation, Classical research, Problem based learning.

The subject of this research is student of class VIII.3 SMP Muhammadiyah 2 Pekanbaru in the secondsemester academic years 2017/2018, which amounted to 25 students. The research consisit of two cycles, each cycle has four stages, which are planning, implementation, observation, and reflection.At the end of every cycle the quiz will be implemented. 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 analysis result of observation sheets indicated the learning process in cycle I were better than learning process in before action and learning process in cycle II were better than learning process in cycle I. 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 quiz I and II. The results of this research showed an increasing number of students learning mathematicsabout knowledge of the basic score (20%)to the first quiz (56%) to the second quiz II (80%). Results of this research indicates that appication of the learning model of Problem Based Learning can improve learning process and increase mathematics achievementfrom the students at class VIII.3 SMP Muhammadiyah 2 Pekanbaru in the second semester academic years 2017/2018.Key Words: Mathematics Achievement, Problem Based Learning, Class ActionResearch
