Objective To investigate and study general the features of teaching design of excellent medical Micro-Lecture works in order to provide references for college teachers to improve their teaching skills. Methods Teaching theories of Dale's Cone of Experience, Merrill Principle, and Blending Learning were used to study twenty prizewinning medical works in the competition comparatively. Blue View Word Cloud Tool was used to analyze word frequency of teaching design key words and produce a word cloud picture. Results The selected topics of excellent medical works were quite valuable. Problem-based heuristic teaching method was applied most frequently. Teaching links generally include leading-in, new knowledge instruction and summary. Case-based leading-in appears most frequently with story-based leading-in the second. The elements of visualization were everywhere.
