    1. Design and Realization of CDIO Elements in Civil Engineering Material Course

    2. Overview

    3. CEM course before reform COURSE OBJECTIVES : Enable students to understand, choose, mix and apply various materials correctly CONTENT: TEACHING AND LEARNING METHOD: ASSESSMENT :

    4. Content of CEM course before reform THEORETIC KNOWLEDGE : Chapter 1 Basic Properties of Materials Chapter 2 Air Hardening Inorganic Binding Materials Chapter 3 Cement Chapter 4 Ordinary Concrete Chapter 5 Construction Mortar Chapter 6 Wall Materials Chapter 7 Building Steels Chapter 8 Water Proofing Materials Chapter 9 Bituminous Mixture EXPERIMENT:

    5. TEACHING AND LEARNING METHOD Basic theoretical principles and knowledge---was accomplished through classroom teaching for 38 hours Experiment----was accomplished through demonstrated and validated for 10 hours

    6. ASSESSMENT : Based on a written examination An experimental report at the end of the semester

    7. CEM course after reform COURSE OBJECTIVES: CONTENT: TEACHING AND LEARNING METHOD : ASSESSMENT :

    8. COURSE OBJECTIVES Understand and apply materials correctly; Understand and practice the process of designing and developing materials; Develop CDIO competencies through a teamwork re-design project.

    9. Content of CEM course after reform THEORETIC KNOWLEDGE: Basic principles and knowledge: the same as reform before an extension knowledge : Knowledge on environmental friendly insulating materials Heat preservation and energy-efficient materials ……. TEAMWORK REDESIGN PROJECTS:

    10. TEACHING AND LEARNING METHOD Basic theoretical principles and knowledge---- was accomplished through classroom teaching for 24 hours and self learning; Extension knowledge --- was accomplished through classroom discussions for 10 hours and self learning ; A teamwork re-design project---- was accomplished through self learning, team discuss, conceive, design, implement, discuss and display their products in classroom, then amend their project and follow another CDIO till to fulfil their aim.

    11. Discuss, Implement and display

    12. ASSESSMENT : Classroom examination Design report and display of products Routine performance

    13. CDIO PROCESS

    14. Project Examples Un-fired bricks Concretes used for underground structure Waterproof materials High temperature resistance concretes

    15. Un-fired bricks Bricks were developed by using shell-lime and fly ash which considering social and resource problem. And the new brick is an environmental friendly insulating material. Results of re-design

    16. Un-fired bricks

    17. CDIO Process for developing unfired brick---step 1 1st, accomplished reference reading and comprehending 2nd, selected raw materials and designed mixture based on the principles of environmental protection and energy-saving. 3rd, applied the first mixture and found that the w/c ratio was high, leading to lower strengths, as shown in Fig.1.

    18. CDIO Process for developing unfired brick---step 2 1st, a further reference reading, team discussion and teachers` suggestions---to modified their mixture 2cd, selected raw materials according to the modified mixture. 3rd, applied the second mixture.

    19. CDIO Process for developing unfired brick---step 3 After the test and analysis for the second designed mixture, the third designed mixture was proposed by the students as shown in Fig.3.

    20. Comments from students Through this project I further realize the virtue of CDIO approach. In the approach we learned how to study, how to communicate and how to cooperate. I have gotten a deeper appreciation of a civil engineer. I realize that we need not only to posses a rich, comprehensive professional knowledge, but also, more importantly, to be professional in learning and conduct

    21. It is true that do more, learn more. We should pay more attention to practical abilities, such as independent thinking and self-learning. Teamwork is not a work easy to be done; each member of a team must have his own unique insight in order to complete the project perfectly. How to communicate effectively, how to screen the useful knowledge, and how to use knowledge are all great challenges for us. It is true that practice is the sole criterion for testing truth. Comments from students

    22. Comments from students The teamwork re-design project of CEM makes us really go into the construction practice. We resisted at first doing this project because we thought the experiment being hard, dirty and tired. However, during the project process we really felt the joy of the harvest of working hard, and understood the knowledge more deep-set through learning from practice. Here, I show my thanks to Teacher Li for providing us the good guidance, and I also thank my classmates for their good ideas to amend my project.

    23. Benefits and Conclusion Master a deeper knowledge of CEM than before. Innovative ideology, analysis ability, system thinking, experimentation and knowledge discovery were effectively enhanced. Ability to communicate with others and capability of self-learning were improved. Strongly value the importance of teamwork and how to collaborate with others.
