Enhancing undergraduates' global perspective and capability development through a collaborative general education subject is both important and challenging. The paper reports the findings based on a case study of a collaborative summer program "Construction for Better Living" between The Hong Kong Polytechnic University and Tongji University. The paper first reviews the background, objectives and student groups of the summer program, followed by analyses of teaching module, student assessment module, and student feedback questionnaire. Finally, five recommendations on the design and execution of a collaborative general education subject are provided.
