Building equipment involves three majors:building water supply and drainage, HVAC and building electricity. Its teaching includes theoretical knowledge, construction drawings and equipment installation. Under the talent training goal of broad caliber, deep foundation and emphasizing practice, the teaching of building equipment has gradually changed from pure theory teaching to the combination of theory and practice. In the teaching mode of question-construction drawing-engineering training, problem-based teaching method is used to strengthen theoretical knowledge learning and emphasize the connection with construction drawing in theoretical teaching, students' practical application ability is improved and theoretical knowledge is consolidated through systematic construction drawing teaching, and students' understanding of equipment installation is enhanced through on-site training or simulated training. The teaching mode focuses on how to better integrate theory with practice and deal with the relationship between theory and practice in teaching. Compared with the course evaluation of pure theory teaching, students' recognition of the course is improved, and the course assessment results show an upward trend. Students change from paying attention to the teaching method to paying attention to the course content. It reflects that this teaching mode can improve the course teaching quality.
