This document summarizes a study that investigated incorporating collaborative action research into an in-service teacher training program in Taiwan. Key findings include:
1) Teachers reported that conducting their own action research helped them learn how to better teach and understand their students' learning.
2) Participating in the training program helped teachers develop their knowledge of designing information gap activities, a communicative language teaching strategy.
3) Teachers perceived that using information gap activities in their own classrooms helped students improve their English vocabulary, sentence structure, speaking ability, and meaningful communication.
4) Teachers learned from collaborating with one another and sharing experiences in the action research group. This collaboration benefited their teaching practices.
