Other forms: dialogics
Dialogic refers to something using or consisting of dialogue. A technique for teaching language that relies on a lot of casual, spontaneous chatting between students might be called dialogic.
The term dialogic comes from dialogue, which can refer to any kind of conversation, especially between two people, or to a discussion that's intended to help people come to an agreement or an understanding. So something that's dialogic is either based on conversation and discussion, or involves conversation and discussion. It's especially used within the fields of literature, education, communication studies, and politics.
