ABSTRACT
The purpose of this study are to: 1) know the quality enhancement of the students’ process inside the class through the implementation of Think Talk Write (TTW) in learning atmosphere and its effect toward the Earth. 2) know the improvement of the students’ learning result through the implementation of Think Talk Write (TTW) in leraning atmosphere and its effect toward the Earth. This research is categorized as Classroom Action Research (CAR). The subject of this research is 33 students of X5 at SMA Negeri 1 Ngemplak in the academic year of 2014/2015. The applied insturments in marshaling the data within this study are: (1) observation sheet and questionnaire to measure quality process of the students, (2) test used to measure the students’ learning result. Validation instruments used within this research are content validity and construct validity. The result of this study shows that: 1) the implementation of Think Talk Write (TTW) could advance quality of the studentss process in learning atmosphere and its effect toward the Earth, 2) the implementation of Think Talk Write (TTW) could improve the students’ learning result in learning atmosphere and its effect toward the Earth. Precentage of the quality of the students’ process in learning in Cycle 1 showed 73.38%, while in Cycle 2 advances into 82.29%. It means there is an improvement for about 8.19%.
