Abstract

Absrtract: The development of science and technology is very influential on the quality of human resources. Quality of human resources derived from the learning process, that is through education. Education is closely related to the development of the curriculum. The 2013 curriculum focuses on students' understanding and activity. The study is based on the limited learning tools of mathematics as a supporter of learning. This study aims to produce a learning device based on discovery learning mathematics on prism and limas material for students of class VIII junior high school that is valid and practical to use. This research is a development research with ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The results showed that the learning tools developed have been valid indicated by the results of design of learning implementation (RPP) and students activity sheet (LKS) assessment with the criterion "valid". Work sheet developed are practically demonstrated by the results of the students' assessment with the criteria of "very practical". The learning tools of mathematics developed have the following characteristics: (a) the learning activities contain the steps of the discovery learning model consisting of stimulation / stimulation, problem identification, data collection, data processing, verification, and conclusion; and (b) contains a scientific approach consisting of questioning, observing, questioning, collecting information, reasoning, and concluding.Keywords: Learning Tool, Discovery Learning, Curriculum 2013, Scientific Approach

Abstract

Abstract: This-research aims to-develop interactive multimedia using a-problem based learning design on coordinate system topic for 8th grade students. The background of this research was development of information and communications technologies which have made some impact on the practice of education and that limited teacher preparation for the use of ICT in teaching/learning process. The research was conducted to provide learning media that can be directly use in Problem Based Learning (PBL). This research used ADDIE development model by Dick-and Carry. Development is done through the following steps:-(1)-Analyze; created a-need analysis, identified problem (needs)-of-the-students;-(2)-Design; drew a-storyboard which presented the contents of the display of interactive multimedia, prepared everything that will be required among the creation of the media;-(3)-Development; made the media on the computer based on the storyboard that has been design;-(4) Implementation and Evaluation; tested the learning media and analysis the result. The research instrument used is validation sheet to assess the validity requirement of learning media and practicality instrument which is in the form of questionnaire of student response toward learning media implementation. The learning media validated by three-validators, then practicality test was-conducted in MTs-Darul-Hikmah Pekanbaru which is tested in a small-group and large-group. Based on the data analysis, the-result showed that interactive multimedia using a-problem-based-learning design on coordinate-system topic belong to the category of very-valid with an-average value is 3.89 and also could be used very well as learning media for 8th grade-students. Recommendation-for-further research is to test the media in learning process to observe the-effect-of-this-learning-media-to-increase-student’s-score-(learning-outcomes).Key Words : Interactive Multimedia, Development, Coordinate System

Abstract: This research is a class action research that aims to improve the learning process and increase learning result of mathematics in grade VII4 SMP Muhammadiyah 1 Pekanbaru by applying the contextual approuch. The subject of this research were the students in the class VII4 SMP Muhammadiyah 1 Pekanbaru that consist of 14 boys and 11 girls at the first semester of academic year 2017/2018. Implementation of the learning process before action to be held, there is a problem of learning that is still focused on the teacher so that students can not find the learning concept and construct their knowledge by themselves. To solve this problem requires a learning approuch where students can actively discover learning concepts so that they can construct their knowledge. The instruments of data collection in this research were observation sheets and students mathematic tests. The observation sheets were analyzed in desciptive narative, while the students’ mathematic tests were analyzed in statistic desciptive. The descriptive showed an improvement of learning process prior to the action on the first and second cycles. The percentage of students who achieve minimum mastery before the action is 28%, at first cycles is 48% and at second cycles is 72%. The result of the research showed that implementation of contextual approuch can improve the learning process and increased the student’s achievement of learning mathematic in grade VII4 SMP Muhammadiyah 1 Pekanbaru in the first semester academic years 2017/2018.Keywords : Student’s Math Achievement, Contextual approuch, Clasroom Action Research.

Abstract: This study aims to produce mathematic learning device in the form of lesson plan and student worksheet using TTW strategy in cooperative learning on the subject of SET for VII grade students. The study model used is 4-D that consist of define, design, develop, and desseminate. The research instrument used is validity device and practicality device. The validity device is a validation sheet to assess the feasibility of lesson plans and student worksheet. The practicality device is in the form of observation sheet of learning process implementation and questionnaire of student response. Learning device developed are validated by three validators. The research trials were is tested in a small group were conducted in SMP Negeri 21 Pekanbaru and large group in SMP Negeri 20 Pekanbaru. Small group trial aims to assess the practicability based on student response questionnaire, while the large group to assess the practicability based on the open questionnaire sheet of learning process implementation and student response questionnaire. Based on the data analysis, it can be conclude that the average value for lesson plan is 3.70 in very valid category which means that lesson plan is feasible to be used and as well as the average value for student worksheet are 3.95, that are in very valid category which means that student worksheet are feasible to be tested. The average percentage of student worksheet valued as very practical with mean score for small group and large group testing are 95.60% and 93.82%. These categories mean that the lesson plan and student worksheet are feasible to used in school.Key words: Mathematics Learning Device, TTW Strategy, Cooperative Learning, Development Research, 4-D Model

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
