Robert Coe, one of the editors of the trusted educational research companion Research Methods and Methodologies in Education outlines some of the questions you should consider when determining what makes a piece of research good or bad. This is a helpful way for researchers to self-assess their own work as well as other research work.

We present here a list of questions that it may be appropriate to ask in evaluating the quality of a piece of research.
