Peningkatan Hasil Belajar Kimia Siswa Melalui Model Pembelajaran Kooperatif Tipe Team Assisted Individualization (TAI) Pada Materi Stoikiometri Kelas X Sma 17 Agustus 1945 T.A 2017/2018

The purpose of this research is to know the chemical study result class x using learning model cooperative type team assisted individualization (TAI). This research using a quasi experiment (experiment apparent ) method. The cooperative model learning type team assisted individualization (TAI) is the independent variable while dependent variable is study result. Design research which is used is two group pretest and posttest. Design population in research is all of students of SMA 17 AGUSTUS 1945. The sample in this research draw from two classes such as class X MIA I as a class experimentation and class X MIA II as a class control. The taking of Technique method of the sample collection done by means of simple random sampling. The result of data processing showed value sig. (2-tailed) < 0,05. So that we can conclude that there is no increasing learning model cooperative type team assisted individualization (TAI) significantly.
