The goal of this research are: 1) the learning outcomes of student’s if using methaphor and prezi desktop applications in math learning is better than the learning outcomes of student who did not receive the same treatment on main subject of the circle 2) the learning outcomes of students who have the higher learning motivation better than the learning outcomes of students who have low learning motivation if using methapor and prezi desktop applications 3) the learning outcomes of students with who have higher learning motivation is better than the learning outcomes for student with low learning motivation if it does not use methapor and prezi desktop application in learning 4) there is or not interaction between the learning with different material presentation and learning motivation toward the results of student learning. This research was quasi experiment with 2×2 factorial design. The population in this study was all eighth grade students of Junior Islamic High School of Durian Tarung Padang Academic Year 2015/2016 consists of 6 classes. Samples were taken randomly, so that get first class VIII.3 as experimental group and VIII.2 as the control group. Based on data analysis conclude that learning by using metaphors and prezi desktop applications produce mathematics learning achievement better than learning without using the treatments on the subject matter of the circle. Mathematics achievement of students who have learning motivation high is better than having a low learning motivation either out of the way of presenting the material to use metaphors and Prezi Desktop, or not, and in this study there is no interaction between the learning by presenting different material and motivation learning on student achievement.

Rapid developments in information technology and communication today is based on the development of mathematics in the field of number theory, algebra, analysis, theory of chances and discrete mathematics. To master the technology and creating future required a strong mastery of mathematics from an early age. Standard mathematical competence and basic competence in elementary school (SD), Junior Secondary School (SMP) and High School (SMA) have been prepared with the intention to develop the ability to use mathematics in solving problems and communicating the idea or the idea of using symbols, tables, diagrams , and other media. At the elementary school where children are in the concrete operational stage and how to effectively communicate the idea of mathematical ideas is to use instructional media. This paper will try to review the instructional media as one means of communication of mathematics learning in elementary school (SD).

The aims of this research is to determine the validity aspects of Realistic Problem Based Learning Model or abbreviated as Reaalistic PBL Model for students of SMK grade X1 semester 1 in Padang. Realistic PBL Model is a learning model developed from Problem Based Learning Model and Realistic Mathematics Education Approach (RME Approach). The development stages of the Realistic Model PBL refer to the Plomp Model consisting of (1) the introductory stage, (2) the prototyping stage which includes planning, evaluation and revision, and (3) the product assessment stage. The validity aspect of Realistic PBL Model is investigated at prototyping stage with 6 test subjects consisting of 4 mathematicians and 1 educational technologist and 1 linguist. The results show that PBL RealisticModel which includes syntax/learning steps, social system, reaction principle, support system and instructional impact and supporting tools, along with learning support tools have fulfilled valid criteria.

This paper study about the interest and the low mathematics learning outcomes of eighth grade students of SMP N 46 Sijunjung in the school year 2017/2018. The aimsof this research are to know:1) the interest of student learning taught by the STAD cooperative learning model, 2) Mathematics learning outcomes from students that taught with the STAD type cooperative model in class VIII SMP N 46 Sijunjung 2017/2018 school year. This research is an experimental research and uses quantitative research methods. The subjects of this study were all eighth grade students of SMP N 46 Sijunjung. The sample taken by purposive sampling technique. The results showed that 1) the interest in mathematics learning of students taught with STAD was categorized as good with a percentage of 84.50% and 2) the mathematics learning outcomes of students taught with the STAD type cooperative model were higher than the mathematics learning outcomes of students taught with conventional learning models. It can be seen from the acquisition of the average value of the experimental class test 81.50 and the average value of the control class test 72.25. The percentage of student learning completeness in the experimental class was 70%, while in the control class 40%. After testing the hypothesis using the t-test, obtained t count> t table (2.68> 1.68) with αi = i0.05 at the 95% confidence interval, then the decision is H0 rejected and H1 accepted.

The purpose of this study is 1) To know the motivation to learn mathematics of taught by using cooperative learning model type Pair Check with reward higher than student motivation taught by convensional learning,and 2) To know the mathematical reasoning ability which was taught by using cooperative learning model type Pair Check with reward on material function is higher than students mathematical reasoning ability taught by convensional learning. This type of research is Quasi Experimental Research with Randomized Control Group Only Design. The population in this study is all eighth grade student of SMPN 19 Padang. In obtaining the sample class it is need to be done normality, homogeneity and equality of classroom average tests the class selected as the experimental class is VIII.5 class and the control class is VIII.3. The result of the research shows that 1) learning motivation of students which was taught by using cooperative learning Pair Check model with Reward is higher than student’s motivation taught by convensional learning. Hypothesis test that is t-score (7.034) > t-table (1.67), 2) students' mathematical reasoning ability after being taught by cooperative model type Pair Check with reward is higher than the students' mathematical reasoning abilities taught by conventional learning models. Seen from the average score of the experimental class test score of 80.16 and the average of the control class test score of 74.13. After hypothesis testing using t-test, obtained tscore > t-table (1.867 > 1.67) at 95%. So it can be student mathematical reasoning ability of class VIII SMPN 19 Padang which is taught by cooperative learning model type Pair Check with reward is higher than taught by using conventional learning.Keywords: Mathematic Reasoning Ability And Student Motivation, Model Cooperative Type Pair Check, Reward Fungsi, And Mathematic
