Abstract: The background of this research is low of mathematics learning outcomes of class VII8 of 21 Junior High School Pekanbaru in first semester of the 2017/2018 academic year. Related to learning outcomes, one of the main factors affecting is the learning process. In line with it, the in order to improve student learning outcomes, it is necessary to improve the learning process. The type of this research is the Classroom Action Research that has purpose to improve the learning process and to increase student’s mathematic learning outcomes by applied the Problem Solving Strategy in Cooperative Learning. This research consists of two cycles that each cycle composed of 4 stages, such as planning, implementation, observation and reflection. At every end of a cycle, math achievement test will be held.The research instrument consists of learning devices that involve Syllabus, Lesson Planand Worksheet, and instrument data collector that involvethe observation sheet and math achievement test. The Observations collected through the observation sheet by narrative descriptive analysis and math achievement test by statistic descriptive analysis.The result of the research showed that implementation of learning process on cycle II had happened improvement from implementation on cycle I. Weakness on cycle I is improved on implementation cycle II according with planning of improvementafter reflection cycle I. Number of students that reach Minimum Mastery Criteria increase from basic score to daily test II. The number of students who reach Minimum Mastery Criteria on basic scor, daily test I and daily test II are respectively 12 person (27,27%), 23 person (52,27%) and 28 person (61,36%). Results of this research indicates that application of Problem Solving Strategy in Cooperative Learning can improve learning process and increase mathematics learning outcomes from the studentsof class VII8 of 21 Junior High School Pekanbaru in first semester of the 2017/2018 academic year at the subject matter of equation and linear inequalitiesof one variable.Key Words: Problem Solving Strategy, Cooperative Learning, Mathematics Learning Outcomes

Abstract : This research is a developmental research which aims to produce computer based learning media of an interactive tutorial model in main value topic for 7th grade of SMP/MTs that is valid and practical. This developmental research used development model based on the teory of Borg and Gall modified by Sugiono (2011). The stages are: (1) potential and problem; (2) literature collection; (3) product design; (4) product validation; (5) product revision; (6) product tested; (7) product revision; (8) product tested in large group; (9) product revision. Product design is through two stages, that are making paper based design and then used microsoft office power point program. The research instrument used a validation sheet that was validated by three experts or validators and participant response questionnaires assessed by students. Assessment of validation data and questionnaire responses of students is done by adapting the formula from Anas Sudijono (2011). The results of the validation of three experts or validators obtained an average score of 3.31 (very valid). The product testing on 6 students of class VII SMP PGRI Pelalawan with an average score of 3.83 (very practical). Furthermore, a trial of use or trial of a large group on 22 students of class VII SMP PGRI Pelalawan with an average score of 3.46 (very practical). Thus, it can be concluded that computer based learning media is valid and practical.Key Words : Computer based Interactive Learning Media, Development, Main Value

Abstract: This research aims to develop mathematics learning device that are Lesson Plan (LP) and Students Worksheet (SW) and 2013 curriculum-based with discovery learning model on the equations and inequalities of linear one varible absolute value material. This development research uses 4D development model who developed by Thiagarajan and modified by Endang Mulyatiningsih. The development carried out by the stages: (1) define; (2) design; (3) development; and (4) dessemination that is not implemented due to time and cost limitations. Data collection instrumen in this study were LP and SW validation sheets and student response questionaires. Then, learning device that had been compiled are validated by three validators and revised according to validator’s suggestions. Then, learning device that had been validated are tested in two stages, namely small group trials with the subject of six students of class X.4 SMA Negeri Plus Provinsi Riau and a large group trial with the subject of 20 class X.2 students of SMA Negeri Plus Provinsi Riau. Based on the data analysis results and the discussion it can be concluded that the 2013 curriculum-based mathematics learning device with a discovery learning model on the equations and inequalities of linear one varible absolute value material was considered very valid with the rating average for lesson plans was 3.63 and the rating average for Students Worksheet is 3.62, and meets the practical requirements for use by the students of grade X SHS.Keywords: Mathematics Learning Device, Discovery Learning Models
