On account of the key problem existing in teaching of civil engineering course, which is separation of theory knowledge from practice, a systematic reformation scheme was put forward based on instantiation thought. By introducing actual cases as “content index” in new teaching material, developing a model room of construction technology and a reference room of actual case, and forming an auxiliary teaching database (video, animation, and site picture), we built a systematic resources platform for teaching and further made reasonable use of the platform in teaching process. As results of course reformation, students can well combine practice knowledge with theory knowledge together during the course of learning and make more clear how and where to use course knowledge. Finally, better combination of theory with practice and better teaching effect can be gained.
