10. TEACHING AND LEARNING METHOD
After reform
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.

17. CDIO Process for developing unfired brick---step 1
After reform
CDIO Process for developing unfired brick---step 1
1st mix design
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
After reform
CDIO Process for developing unfired brick---step 2
2nd mix design
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.
Polymer was added, the w/c ratio was reduced

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

After reform
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

Comments from students
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
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.
——Lihua Chen

23. Benefits and Conclusion
After reform
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.
