It has been exploring changes and improvements in materials,personnel composition,organization mode,etc.ever since 2013. And it has gradually developed from a course practice into a challenging and enthusiastic competitive social activity with primary school group, middle school group and university group engaged.The whole project consists of four parts, namely assignment, development, preparation and Construction.In the end,the course requires students to use real building materials for outdoor on-site construction within a certain time limit (usually 8 hours in a row), and requires the built space to be able to overcome the influence of self-weight, self-deformation and external force, and to provide stable, reliable and communication space for people within a predetermined time period. Details of teaching links,task requirements,teaching methods,etc.are shown in fig. 2.During the development of the program, regular teaching seminars on curriculum improvement and teaching methods were hold.
