"The purpose of the review is to learn from the evidence to inform the development of a graduate level training programme in England and Wales. The review, inspired by a realist approach, includes a total of 33 studies conducted in a number of countries. Key training contexts, mechanisms, and outcomes were examined to determine how training works, under what conditions, and for whom. Findings indicate that student-centred teaching approaches were found to promote critical thinking and problem-solving skills."
