As a supplement of steel structure course, Tongji University took the lead in building a multi-functional test platform for teaching in P. R. China, on which a course named basic principles of steel structures was offered. The test course included cognition test, demo test and self-designed test for students of different levels. Practiced and explained by teachers, a large variety of tests in close accordance with syllabus were included in demo tests, which could deepen students’ understanding of basic theories and make up for the disadvantage of classroom teaching. Self-designed tests were designed and practiced by students, which could improve their practical abilities and study initiative. Within three years of practice, 1 500 students have been involved in the test lessons. The test course achieved good teaching effect.
