This study aimed to examine comprehensively the effect of the application of REACT learning models based on the Malay cultural context of Riau on students’ mathematical problem-solving abilities. The research was a quasi-experimental research with Pretest-post-test control group design. The sample of this study was all students of class VII SMP 12 Pekanbaru. The results of data analysis were: (1) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning; (2) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning in terms of aspects of student ability levels, (3) There was no interaction between the learning model and the level of students’ ability to the ability to solve mathematical problems; (4) There was a difference in the mathematical problem-solving ability of Pekanbaru junior high school students who learned to use the REACT learning model based on the Malay Malay cultural context in terms of aspects of student ability levels.

This study aims to determine the effectiveness of learning with a scientific approach in the STAD-based cooperative model lesson study of learning outcomes in mathematics. This research is a quasi-experimental study. The study population was junior high school students in Rokan Hilir Regency which were divided into three school levels; upper level, medium level and lower level. The research sample was taken randomly (clustering random sampling). Each sample contained an experimental class and a control class. The research instruments were learning devices and instruments for collecting data. The design of hypothesis testing of student learning outcomes in the form of pretest and posttest data analysis through statistical tests. The data was analyzed using integrated statistical tests. The results showe that student learning outcomes in the experimental class were better than the control class for each level. There are differences in student learning outcomes in the experimental class viewed from the school level, and learning with a scientific approach in cooperative type STAD-based lesson study is effective in terms of student learning outcomes. The conclusion is that the learning with the scientific approach in the STAD-based cooperative model is effective.

Development of Mathematics Learning Tools in the Context of Riau Malay Culture to Improve Students Mathematical Problem Solving Ability Resmi Rianti; Sehatta Saragih; Zulkarnain Zulkarnain

This research was motivated by the lack of learning devices that are considered to be able to train students mathematical problem solving abilities. The purpose of this study was to develop mathematical learning tools that meet the valid, practical, and effective requirements to improve the mathematical problem solving abilities of students in grade VIII SMP on flat side space. The development model used was the 4D model. Based on the results of the validation data analysis, it was concluded that the learning device developed was valid. The results of the syllabus validation were 80.56%, RPP 81.43%, LKPD 87.34%, pretest questions 78.94%, posttest questions 79.86%. This learning tool fulfills the practical requirements in large group trials with an average performance result of 93.06% and an average questionnaire response of students 91.21%. The use of effective learning tools has improved the student learning outcomes. Development of learning tools can significantly improve students mathematical problem solving abilities at a significant level of 0,000 with α = 0.05. This shows that the learning tools that was developed already meet the valid, practical, and effective requirements and can improve students' mathematical problem solving abilities.

Application of Cooperative Learning Models of Think Pair Shere Type to Improve Student Mathematics Learning Outcomes Andri Saputra; Zulkarnain Zulkarnain; Sehatta Saragih

The low mathematics learning outcomes can be an indicator of student difficulty in learning mathematics. This study aims to analyze the influence of the application of the cooperative learning model Think Pair Share (TPS) type to the results of mathematics learning. This research used quasi-experimental research with sampling using stratified techniques and random sampling. The population was seventh grade students at SMP 17 Pekanbaru, SMP 12 Pekanbaru, dan SMP 36 Pekanbaru. The instrument of this research was a daily test on the quadrilateral and triangle material to see student learning outcomes before being given treatment and after being given treatment. Statistical analysis was performed by Normality, Homogeneity Test, Independent Sample t-test, One Path Anova test, Two Path Anova Test. From the results of the collation test results obtained that p = 0.4425 and p = 0.4005, Ho is accepted, so there is no difference between the experimental class and the control class as well as the high school there is no difference, but the students' mathematics learning outcomes are reviewed from the level there are differences in the middle and lower schools. Generally, TPS learning is good at medium and low schools because in the learning process students still want to share knowledge with other students.

The fact that students' mathematical representation abilities are still relatively low is an issue that continues to this day in the education sector. One of the factors that influence this issue is the lack of evaluation and habituation of students in solving mathematical problems that facilitate mathematical representation abilities. Good instruments certainly need to support these evaluation and habituation efforts. This research aims to produce an instrument for assessing students' mathematical representation abilities that meets criteria that are valid, reliable, have a good discriminatory item value, and good level of difficulty. This development research uses the Borg and Gall development model, which is carried out up to the main fields testing stage. From the research results, a set of instruments for assessing representational ability in Three - Dimensional topic which amounted to 15 questions, with 8 questions in Question Package 1 and 7 questions in Question Package 2, which met the criteria for validity, reliability, and have a good discriminatory item value with a good level of difficulty too. The instrument for assessing students' mathematical representation abilities was developed from these results and met with good final results.

This research is aimed at developing computer-based media formathematics learning. This media used interactive model to help studentsunderstand the topic of lines, angles and rectangular. This developmentresearch applied development model by Borg and Gallmodified bySugiyono.The study began by finding the potentials materials and itsproblems followed by astudy of literature. The subject in this research isline, angle and rectangular,including rectangle, square and trapezium.Product design was done through two stages: paper-based design andcomputer-based. The applications used for product design are MicrosoftFrontpage, Microsoft Power Point and Photoshop. Learning media werevalidated by three experts or validators and were revised based on the inputfrom the validators. The revised learning media were tested on two stages: asmall group test consisting of five respondens and a large grouptestconsisting of forty respondens. Based on the analysis of data and discussion,it can be concluded that computer-based mediafor mathematics learning isvalid with an average score of 3.17 on aspect of materials and 3.18 fromaspects of media. This computer-based media formathematicslearning alsohad practicalities with an average score of 97,92% on a small group test and99,22% in the large group test.
