Through this study, the important issues for planning open-plan learning environment were summarized as follows:
1. Teachers are satisfied with ‘open space’ for various learning style and they want to use open spaces more conveniently.
2. Teachers recognize advantage of open-plan learning environment in terms of learning effects and psychological aspect. However, if the indoor environment such as acoustic condition has significant problems, teachers don't highly evaluate the open-plan.
3. Open-plan learning environments work properly in the cooperative teaching management system by each grade.
4. When student numbers exceeds the capacity of learning environment, it is difficult to manage a grade as a group. In this case, class activities are mainly managed by each class and the class uses open space as an extension of its classroom.
5. Teachers require the classrooms that can be both open and closed condition with appropriate acoustic performance for open-plan learning environment.
