Abstract: This research is classroom action research that aims to improve learning process and to increase mathematics outcomes by applied the learning model of Problem Based Learning. The subject of this research is students in VII3 class of SMPN 8 Pekanbaru in academic years 2017/2018, which amounted to 36 students, consist of 17 boys and 19 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 descriptive, while the students mathematic tests were analyzed in statistic quantitative descriptive. The qualitative descriptive showed an improvement of learning process from before the action to 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 research showed the number of students that reach Minimum Mastery Criteria (KKM) for knowledge increase from the basic score (38,89%) to (55,56%) at the first test and to (72,20%) at the second test. For the skills, the score increase from (55,56%) at the first test, to (69,44%) at the second test. The results of this research showed that appication of the learning model of Problem Based Learning can improve learning process and increase mathematics outcomes for students in VII3 class of SMP Negeri 8 Pekanbaruin academic years 2017/2018 for the subject matter Algebra Operations and Functions.Keywords : Mathematics Outcomes, Problem Based Learning

Abstract

Most of the lecturers do not give great attention or not considered the importance of teaching materials. This is reinforced by the lack of existed teaching materials that to supports the lectures. This study aims to develop competency-based teaching materials in for the subjects of Initial Value Problem and Boundary Condition (IVPBC) to build students higher-order thinking skills. This research is a development research consisting of three main stages, namely preliminary analysis, product design, and development. The object of this research is competence-based teaching materials in the subject of the initial value problem and boundary condition itself. After designing the teaching materials, then it was tested and validated by experts. The instrument used is a validation sheet consisting of 35 statement items. The result of the research shows that all validators have approved every aspect of assessment of teaching materials that are (1) relevance, (2) accuracy, (3) completeness of the presentation, (4) presentation system, (5) conformity of the presentation with the demand of student-centered learning, (6) presentation technique, (7) Indonesian language compliance and (8) legibility and communicativeness. As the conclusion, the developed teaching materials are valid and can be used on a wide scale of teaching.

Abstract

The purpose of this research is to repair the mathematic learning process of Initial Value Matter and Boundary Requirement (IVMBR) course. The variables which have been examined (1) the activities of lecturer and students in learning process, (2) the development of student grades, and (3) the completeness of student result in studying of IVBVP. These actions have been done in three cycles based on data’s analysis, we get the result (1) the lecturer and students activities in learning process have been improved, (2) the development of student grades is rather the same in three of the cycles, and (3) the student who could reach the studying completely. After first cycle, these students get A or B increasing to 62,50,`4%, and after second cycle, the completeness of study has increased to 66,67%, and after third cycle, the completeness of studying have increased to 75,00%. Based on these informations, the constrctivism learning is good to use in learing of IVMBR course.

Abstract

Limited learning instruments for innovative mathematics where students are used as learning centers in accordance with the demands of the 2013 curriculum. The innovative learning instruments referred to in this study are a learning tool in the form of learning implementation plans (RPP) supplemented by student worksheets (LKPD) based on experiential learning model. This model allegedly corresponds to the characteristics of teaching materials and characteristics of students. This study aims to produce learning tools based on experiential learning models on the material of cube and beam of class VIII SMP with a high level of validity and practicality. The form of this research was development research (R & D) using ADDIE development procedure; analyze, design, development, implementation, and evaluation. The object of this study is to develop a learning instrument based on experiential learning model on the material of cube and beam of class VIII SMP itself. After the RPP that is equipped with LKPD is declared valid by the expert, a trial is conducted on a larger class to examine the practical aspects. The subjects of the trial were 38 eighth grade students of SMP 21 Pekanbaru. The instrument used is a validation sheet consisting of 34 statement items and student response questionnaires to LKPD. The results of the study are that all validators have agreed on every aspect of assessment of the learning instrument, namely aspects of 1) format of learning instrument, 2) activities of the entire contents of learning instrument, 3) content of learning instrument, 4) pictures or graphics, and 5) language / text and 6 ) overall assessment of learning instrument. Then based on the results of data analysis about student response questionnaires to LKPD, it is obtained that 95.5% is with a very practical category. It can be concluded that innovative learning instruments in the form of RPP equipped with LKPD are based on experiential learning model on cube material and grade VIII SMP beam can be used in learning with a high level of validity and practicality.

Abstract: This research was done due to the problem found by the teachers' difficulties in developing learning instruments based on Curriculum 13. It needed certain learning instruments to increase students’ knowledges and makes them able to solve problems in their daily life. This research was purposed to make a syllabus, lesson plan, and LAS by using PBM (Problem Based Method) in System of Two Variable Linear Equations Material for Junior High School Students Grade VIII. It was Research and Development design with 4-D models; defining (pendefinisian); designing (perancangan); developing (pengembangan); disseminating (penyebaran). This research was done until third model because of the financial limit. The instruments used were learning instruments validation paper and questionnaire. Syllabus, leasson plan, and LAS were validated by three validators, then it revised and the researcher did tryout test for a small group (consisted of nine students) and large group (consisted of twenty students) at SMPN 14 Pekanbaru. Based on the analysis result, it showed that the validation for syllabus, lesson plan, and LAS with a Likert scale by average 3.70, 3.80, and 3.77 was valid. Besides, for the questionnaire result showed that 88.3% for small group and 95.2% for large group. Based on analysis result and explanation, it can be concluded that syllabus, lesson plan, and LAS by using PBM (Problem Based Method) in System of Two Variable Linear Equations Material for Junior High School Students Grade VIII is practical and suitable for Junior High School Students Grade VIII.Key Words: Problem Based Method (PBM), Mathematics Learning Instruments, System of Two Variable Linear Equations, Validity and Practicality.
