Medical education is a lifelong learning continuum that begins with undergraduate education and extends through postgraduate education and continuing professional development. It aims to train medical professionals to promote health and relieve suffering. Traditionally, medical education combined didactic classroom instruction with hands-on clinical learning. However, there is now a greater emphasis on self-directed and problem-based learning, using technologies like e-learning. Effective knowledge transfer remains a challenge with the growing amount of information. Medical teachers also need to adapt to changing models of education that focus more on students and active learning rather than traditional didactic lectures. The ideal physician of the 21st century requires strong communication skills and the ability to apply evidence-based practices and lifelong learning.
