Introduction to Digital Publishing
Improving the student learning experience Student evaluations communicated that learning materials were scattered across a wide range of formats and locations—the cognitive load was high, and it was getting in the way of their learning. Our team set out to improve students’ experience with faculty-created materials. The goal of the Digital Publishing and Instructional Design […]

To live up to the highest ideals of medicine and to “first, do no harm,” physicians must have a deep understanding of the evidence base that informs patient care and the ability to continue growing their knowledge throughout their careers. Learning the scientific method and basic scientific and ethical principles of clinical and translational research, […]
