Abstract: Based on the disadvantages of the teaching of civil engineering computer aided drawing (CAD) course and the pressure of continuous compression of class hours, the teaching reform scheme of CAD is presented in three aspects including teaching means, teaching methods and evaluation methods. According to different knowledge points in CAD teaching, 121 micro-videos with averaged duration of 3–5 minutes were recorded. Then a network course named computer drawing micro-course was developed on the platform of Chaoxing Xuexitong, which supports online study on personal mobile devices such as mobile phones and iPad in fragmentated time. Based on the micro-videos, the task-driven method and flipped classroom are adopted to carry out teaching, which could shorten the class time by 1/4 and focus on the cultivation of students’ innovative learning ability. What’s more, theory examination of CAD is cancelled, but the completion of micro-video self-study, homework, performance in flipped classroom, creation of 3D model and examination on computer are all included in the assessment, aiming to strengthen the management of learning process and the practical drawing ability with computer. Compared with the traditional classes, the pilot classes that adopted the scheme not only shorten the class hour, but also raises the average score of final examination on computer by about 4 scores, which demonstrates the feasibility of the proposed teaching reform scheme.
