Threshold Concepts in Preclinical Medical Education: Students' Perceptions.

Threshold concepts are those ideas that learners often find difficult, but must understand in order to master a discipline. Nearly all research into threshold concepts has been from the perspective of teachers. We argue that the students' perspectives can also be helpful. In this commentary, we explore this issue and inform the debate by drawing on insights from a pilot study in which medical students articulated their own views on what constituted threshold concepts from recent learning experiences in physiology. Combining insights, from teachers and students, into candidate threshold concepts could be used to improve the medical curriculum.
