This research entitled "Application of Think Talk Write Model (TTW) to Improve Communication Ability of Grade XII Students on Biology Learning". This research is a classroom action research that aims to know the level of student communication in oral and written by applying Think Talk Write (TTW) learning model on Growth and Developmental materials in Cycle I and Enzyme (Metabolism) materials in Cycle II. The data of students' oral communication ability is obtained from the observation sheet to observe the achievement of the students' communication ability indicator orally on the learning activity. While the data for students' communication skills in writing obtained by using the test in the form of a description of 10 numbers. Ability to communicate students orally in the first cycle of 53.80%, while in the second cycle increased to 73.02%. While the results of the ability to communicate in writing showed the results of 71.55% in cycle I and increased to 83.97% in cycle II. Based on the results obtained, it can be concluded that the application of Think Talk Learning (TTW) model can improve communication ability of grade XII students in Biology learning. © Published under licence by IOP Publishing Ltd.
