Penggunaan Model Pembelajaran Problem Posing Tipe Post Solution Posing Untuk Meningkatkan Hasil Belajar Kimia Siswa Kelas X IPA SMA Pusaka 1 Jakarta

Declining average value of computer-based national exams in 2017, proves that chemistry learning in Indonesia is not optimal yet. Initial set at Pusaka 1 East Jakarta High School, the interest in studying chemistry students is not directly proportional with the learning outcomes. This is because of the students' understanding ability low. The use of problem posing posing posing learning models forcing people who make similar and deficient questions like that exemplified by the teacher. This study aims to: (1) Know the increase in results learn student chemistry using problem type posing learning models post the posing solution. (2) Knowing the level of improvement in student chemistry learning outcomes by using the posing posing pose posing learning problem model. This study uses a pre-test and post-test only control design. Population The study was all students of class X Science at Pusaka 1 Semester II Year High School 2017/2018 lesson with a permanent sample of 55 students determined in a way purposive sampling. Class 10 Science 2 as an experimental class using the model posing posing pose posing learning problems, while 10 Science 3 as Control class uses one-way interactive lecture learning with questions answer with students. The research instrument was in the form of a question test. Test analysis Shows data that is normally distributed and is homogeneous. Hypothesis testing using paired samples t test with a significance of 0.05 results t count of 20.67 and a significant value of 0.00. Data analysis and testing the hypothesis assisted by SPSS 22, obtained the following results: (1) there Improve student chemistry learning outcomes by using learning models posing posing problem posing problem. (2) Increasing student chemistry learning outcomes by using the posing posing pose posing learning problem model by 76%.
