The invention discloses a construction engineering cost teaching demonstration method. The invention relates to the field of engineering cost teaching. A central processing module is included, whereinthe connection end of the central processing module is provided with a login module, a courseware storage module and a learning quality detection module, the connection end of the learning quality detection module is provided with a learning quality evaluation module, the connection end of the central processing module is further provided with a learning history recording module and a retrieval module, and the central processing module comprises a central processing unit. According to the invention, the learning quality detection module is used for carrying out learning content vacancy filling, learning key point vacancy filling and exercise test on the content learned by students; and then the learning quality evaluation module compares the duration and the score consumed by personal learning with the average value of the duration and the score respectively, so that the learning quality evaluation score can be obtained in time, and compared with the prior art, the teaching effect canbe effectively improved.
