The research objective is to obtain an appropriate media and learning physics can help understanding the basic concepts in physics learning, especially for the completion of a straight motion of matter in the junior class VII. The study design used in this study is a 2x2 factorial design with three variables, namely instructional media, interest in student learning, and learning outcomes Physics. The samples obtained through the Multi Stage Sampling, each 13 person for 4 classes, so that individual large sample size of 52 students. Data analysis using ANOVA of two lines techniques, and first performed a descriptive statistical analysis and test analysis requirements. The results showed that: 1) there is the differences of learning outcomes of students who were taught physics learning media fascination with physics and conventional instructional media, 2) there is the differences of learning outcomes of students who are interested in studying physics of high and low learning interest, and 3) there is an interaction effect of learning media and interest in learning the results of learning Physics.

Tenaga pendidik merupakan unsur terdepan yang menentukan kemajuan sebuah bangsa. Tenaga pendidik yang kompeten sangat menjamin perbaikan kualitas sumber daya manusia di sebuah negara, sehingga tidak berlebihan jika mengatakan bahwa guru memang harus memiliki kompetensi yang luar biasa. Akan tetapi, kenyataan di lapangan menunjukkan bahwa guru belum memiliki kompetensi yang memadai, terutama dalam hal mendesain pembelajaran, penelitian, dan juga penguasaan bahasa asing, khususnya bahasa Inggris. Perlu solusi yang cermat untuk mengatasi permasalahan kompetensi guru, beberapa diantaranya adalah dengan memperbaiki sistem kurikulum perguruan tinggi, khususnya LPTK, sehingga dapat mengakomodasi kesenjangan yang dimiliki oleh guru. Selain itu, perlu diadakan berbagai model pendidikan dan pelatihan yang sesuai dengan kebutuhan para guru, serta dilaksanakan secara sistematik dan komprehensif, sehingga target yang diharapkan dapat menjadi kenyataan.

This research aims to develop MONOTIKA learning media (Monopoly Mathematics) and test the feasibility of MONOTIKA learning media (Monopoly Mathematics) in algebraic materials for middle school students. The learning development model is the ADDIE design model. This study's sources of needs analysis are SMP Negeri 126 and SMP Negeri 209 east Jakarta area. Data collection techniques used are teacher interviews and polling stations. Validation of the development of this learning media between 2 validators is material experts and media experts and students response usage if MONOTIKA media is used in schools. This media trial was conducted on 41 students in grades 7 G and 7 H at SMP Negeri 209 Jakarta. This study showed that MONOTIKA (Monopoly Mathematics) obtained a total average score for all aspects of all is 4.50 material expert validity and 4.28 valid expert media, which is an average media that deserves good both as a learning medium. Student poll results showed an average score of 4.47, which the average student gave responsibility for positive MONOTIKA (Monopoly Mathematics). Thus, the results of the development of MONOTIKA (Monopoly Mathematics) learning media for junior high school students in grade VII are valid and eligible for use.

This research aimed to make the development of an effective instructional design for Elementary School student’s class 1 to facilitate the development of mathematics learning process based on expert assessment, the achievement of problem-solving abilities, and the student’s response. The development Procedure is adapted from instructional development models M. Atwi Suparman including the step definition, analysis and development of a prototype system, and conducting formative evaluation. The yielded products included of book learning model, student activity sheets, and student test results. This product has several times revised based on suggestions and feedback from lecturers, validators, and limited testing. The results showed that (1) the quality of the Mathematics learning materials Grade 1 of Elementary School based on expert assessment is fair; (2) the students response to the learning material products classified as very positive. After using Math instructional design is expected to facilitate either students or teacher of elementary school in Mathematics Learnig Grade 1.

Human beings as social creatures need cooperative with others due to their independencies. It means that cooperative is needed by all the people. Recently, some of the problems in education are the students’ cooperative is still not optimal and the low point of students’ achievement in the learning process. In cooperative learning, one of the methods is Think Pair Share method that can improve the students’ achievement. This method is focused on student-center that allows students to think independently forming ideas of their own then they are grouped in pairs to discuss their thoughts and train their social interaction to articulate their ideas and to consider those of others. Improving the students’ teamwork in cooperative learning through Think Pair Share habitually will achieve the purpose of studying.

Penelitian ini dilakukan untuk memperoleh gambaran tentang pengaruh model pembelajaran kooperatif terhadap kemampuan berpikir kreatif matematis siswa.Metode penelitian yang digunakan yaitu metode eksperimen. Sampel dalam penelitian ini diambil dengan teknik simple random sampling dengan jumlah 60 orang terdiri dari 30 kelas eksperimen yang diajarkan menggunakan Jigsaw dan 30 kelas kontrol yang diajarkan menggunakan Think Pair Share (TPS). Instrumen untuk pengambilan data berupa tes uraian. Uji normalitas data menggunakan Chi-Kuadrat dan uji homogenitas menggunakan uji Fisher. Pengujian hipotesis menggunakan uji-t, menunjukkan thitung = 2,286 > ttabel = 2,002 dengan =0,05yang menyatakan bahwa H0 ditolak, sehingga dapat di simpulkan bahwa terdapat perbedaan kemampuan berpikir kreatif matematis peserta didik yang diajarkan menggunakan model pembelajaran Jigsaw dan Think Pair Share (TPS). Dengan demikian terdapat pengaruh model pembelajaran kooperatif terhadap kemampuan berpikir kreatif matematis peserta didik.
