Aiming at the current situation that different course sequences and teaching arrangements of computer graphics exist in civil engineering specialty in our country’s applicationoriented undergraduate colleges,this paper researched the teaching effects of different course sequences and teaching arrangements on computer graphics by teaching experiments to 319 “the second batch of undergraduates” and “the third batch of undergraduates” from nine experimental classes,and evaluating the above teaching experiment results from quantitative course scores and qualitative surveys.Results show that the teaching effect of computer graphics and descriptive geometry and civil engineering drawing followingup method is well better than simultaneous method; when teaching computer graphics to applicationoriented undergraduates,the method of teaching and studentdrawing at the same time is not as good as the method of teaching firstly and then studentdrawing; the computer graphics learning effect of “the second batch of undergraduates” is generally better than that of “the third batch of undergraduate” whose learning polarization should be paid attention to by teachers.
