Teachers teach computing, whereas computing education researchers make discoveries about this teaching and learning, and invent new ways for these teaching and learning to occur. CER is an example of discipline-based education research, like math education research or science education research, all of which are part of the broader field of education and learning sciences research.

CER is also not educational technology. Computing education researchers often create educational technologies to support the learning and teaching of computing, but CER is not explicitly concerned with the
