As a basic clinical course, diagnostics learning needs to practice hardly and frequently.The traditional teaching and examination mode of physical examination and electrocardiogram (ECG) for students was short of guidance and practice, and the workloads of manual paper marking was burdensome.Therefore, our office and department of mathematics office have developed a self-regulated learning platform of diagnostics which provides plentiful medicine resources for studying.It enhances students’ self-regulated learning ability, improves the work efficiency of teachers, and strengthens the teaching effect of diagnostics.
