In this paper, the authors reveal how learners evaluate different learning environments including CSCL and classroom, and how learners describe relationship between different groups in some learning environments. In order to demonstrate these relationships, they try to use combinations of qualitative semi-structured interviews and a collage method, which facilitate learners externalization of relation among learning environments and groups. They especially focused how learners describe CSCL on collages. As a result, three types of collages were found showing different relations. It is suggested that a collage method is useful for learners to transform internal thought into outer representations. hi addition to these effects, this method has possibilities to reconstruct their thinking more clearly. As a whole, it is suggested relations making like collages is important for learners to reflect about learning environments.
