What is Medical Education Research? provides an engaging and novel way of introducing learners and the public to the ins and outs of medical education research. It also demonstrates the unique interests and interdisciplinarity of medical education research. To create the content for the book, we interviewed editors from prominent medical education journals. The book generates understanding and awareness of medical education research, encourages more individuals to engage in medical education research, and motivates others to embrace innovative knowledge mobilization in medical education.
