This research was conducted to improve students' English speaking ability by using the think-pair-share strategy designed in CAR. The findings in Cycle 1 was unsuccessful because the students' average scores was 74.18 and classroom atmospheres were "mid" that did not meet the criteria of success. Therefore, the implementation of the strategy was continued cycle 2 by revising the plan. The students' average score in cycle 2 achieved 81.68 and classroom atmospheres were "mid." It means that the results in cycle 2 met the criteria of success and judged as successful. So, it can be stated that the think-pair-share strategy was effective to be implemented at STAIN Ternate in order to improve the students' speaking ability.
