Application of Team of Accelerated Instruction Cooperative Learning with Problem Solving

This research aims to improve the activity and learning outcomes of science through the application of cooperative learning type of Team Accelerated Instruction (TAI) with problem solving method on the fifth grade students.Based on preliminary observation at elementary school researchers found problems on learning science in the fifth grade.Teachers have not used varied models and learning media, so it made the passive students and have not spirit to follow the learning process.This type of research is a classroom action research was conducted through planning, action, observation, and reflection.The sample of the research is on the fifth grade of 30 students.Based on activity results and student learning results can be concluded that TAI learning models can improve activities and outcomes of science, especially thermal energy material and its sound and properties.Based on the results of the study suggested in class V teacher to use TAI model, because by using TAI model can make students active and can improve the results of science study.This is evident from the results of students ' activities and learning outcomes.Besides, TAI models can also motivate students to learn and work on questions, and students can play an active role during the learning process.
