The purpose of this study is to systematically analyze the research published in domestic research and derive strategies to promote teacher collaboration for instructional design. In contrast to simply understanding research trends, systematic review is intended to give implications to practice through analysis of research results. For this purpose, this study used the Meta-aggregative approach for analyzing 19 qualitative studies on teacher collaboration during instructional design. As a result, 6 promoting strategies are emerged; (1) Share the goal of teacher collaboration. (2) Let participants exchange opinions on instructional design freely.
(3) Carry out the role of the leading teacher to promote teacher collaboration. (4) Use online tools for sharing. (5) Ensure a formal and informal environment for teacher collaboration. and (6) Differentiate evaluation feedback in accordance with target teacher or students. Through analysis of the results, some suggestions for implementation are provided when educational administrators, school administrators, teachers, and learning community members are interested in promoting collaborative instructional design.
