Conclusions School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

3 Introduction  Traditional Approach to Teach Structural Analysis & Design Modules  A series of lectures on physical laws, mathematical tools and methods for structural analysis and design  Students are passive recipients  Supplemented by a few laboratory experiments on scaled-down models in different sessions at different places School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

4 Introduction  Perceptions of Civil Engineering Students on Structural Analysis & Design Modules  Abstract  Dry  Difficult to visualize and understand  Killer modules  No confidence to pass  … School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

5 Introduction “Tell me, and I will forget. Show me, and I may remember. Involve me, and I will understand.” Confucius ( B.C.) School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

6 An Innovative Solution For Real-Time Experiential Learning of Large Structures  Conceiving Stage (brain-storming sessions)  Adopted two-pronged approach  applied systems thinking  consulted relevant staff members  consideration of future implementation of CDIO as the context for civil engineering education School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

7 An Innovative Solution For Real-Time Experiential Learning of Large Structures  Solution To upgrade an existing laboratory space and design-build- operate a real size structural system to give students integrated hands-on learning experience School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

8 An Innovative Solution For Real-Time Experiential Learning of Large Structures  Why this solution is Innovative? a)Motivating students in understanding of structural concepts and behaviours. b)Integrating discrete and disconnected experiments across different structural engineering modules. c)providing a conducive learning environment within existing laboratory that was used for concreting and building technology work, and d)providing a platform for implementing principles and standards of CDIO in the context of civil engineering education. School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

9 An Innovative Solution For Real-Time Experiential Learning of Large Structures  Designing Stage  Developed design specifications  Carefully selected a consultant  Worked closely together with the external consultant  Issued drawings to an external contractor for construction School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009

10 An Innovative Solution For Real-Time Experiential Learning of Large Structures  Construction Stage  Played roles of “site supervising engineer” and “product system operator”  Worked closely together with the external consultant and contractor School of Architecture and the Built Environment The 5th International CDIO Conference, Singapore Polytechnic, Singapore, June 7-10, 2009
