<p>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 <br />learning media and interest in learning the results of learning Physics. <br /><br /></p>

<p>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.</p>

<p>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. <br /> <br /><br /></p>

<p>The aim of this research is to know the influence of mathematical communication skills of the students toward the learning result (achievement) in junior high school in Jakarta. The research method which was used in the research is survey method. The population of research is all students in junior high school in Penjaringan, north Jakarta. Samples are taken by simple random sampling, consisted of 34 students. The research instrument is mathematical communication skills of the students and mathematics learning achievement. Data analysis employed regretion correlation. The hypothesis testing resulted in conclusion: there a positive correlation of mathematical communication skills of the students toward the mathematics learning achievement. <br /><br /></p>
