Uji yang digunakan untuk mengetahui adanya perbedaan rata-rata gain adalah uji t. Berdasarkan hasil penelitian, rata-rata gain kemampuan pemecahan masalah siswa yang memperoleh pembelajaran dengan model  pembelajaran problem posing tipe post solution posing adalah 13.91, sedangkan rata-rata gain kemampuan pemecahan masalah siswa yang memperoleh pembelajaran secara konvensional adalah 7.09. Dengan uji t terlihat bahwa rata-rata gain kemampuan pemecahan masalah siswa yang memperoleh pembelajaran problem posing tipe post solution posing lebih baik daripada siswa yang memperoleh pembelajaran secara konvensional.  Disarankan guru dapat terus mengembangkan pembelajaran dengan model  problem posing tipe post solution posing dan menerapkan pada materi lain.The purpose of this study was to determine the effectiveness of applying the problem posing learning model type post solution posing to students' problem solving abilities in one of the junior high schools in the Semarang city. This research is a quasi-experimental study with a pretest-posttest design. Sample selection was determined by random sampling technique and was obtained by students of class VII A as an experimental group and students of class VII B as a control group. The instrument used for retrieval of research data is a problem solving ability test on the subject of rectangles. The test used to determine the difference in average gain is the t test. Based on the results of the study, the average gain problem solving ability of students who get learning with problem posing learning model type post solution posing is 13.91, while the average gain problem solving ability of students who obtain conventional learning is 7.09. With the t test it can be seen that the average gain of problem solving abilities of students who get problem posing learning model type post solution posing is better than students who get conventional learning.

Abstract. The research problem is the low level of student learning independence in learn-ing physics that have an impact on the low student learning outcomes. The purpose of this study was to find out the improvement of the independence of learning physics that has an impact on student learning outcomes using cooperative learning model of Numbered Head Together type assisted edmodo. This research use quasi-experiment design. The population in the study was all students of class X SMK N 2 Medan. The research sample consisted of 2 classes, each of which consisted of 30 students, use cluster random sampling technique. Data collection techniques for measure learning independence in form of multiple choice questionnaires totaling 15 items. Data analysis techniques used include normality test, homogeneity test, t-test, and N-gain test. The re-sults of study using the t-test obtained by tcount 4,863 while the t table was 2,002. So that t count> t table (4.863> 2.002) then Ha is accepted and the N-gain test shows that there is an increase in student learning independence of 0.07. From this study it can be concluded that through Edmodo assisted type Numbered Head Together cooperative learning model can increase the independence of students' physics learning. Abstract.
