A new construction practice mode of a group practicing in multiple sites is put forward in the paper. In this mode, the group conducts cross-site practice in the projects at different construction schedule within a limited practice time, the students can fully understand the whole construction stages of the foundation engineering, the main structure and decoration engineering, and some problems existed in the single site practice is solved; and at the meantime, the tutor of the construction project will guide the students in the whole practice, it will help the student quickly master the project overview and key construction technology. Moreover, the processes and characteristics of this group practice mode have been introduced, and a comparison analysis with the traditional scattered practice has been carried out in the paper. The practice study shows that the practice mode of group practicing in multiple sites is effective.
