  accomplished through classroom teaching for 38
  hours
• Experiment----was accomplished through
  demonstrated and validated for 10 hours

COURSE OBJECTIVES
Before reform

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

Content of CEM course after reform
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
After reform

• 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.

Project Examples
After reform

• Un-fired bricks
• Concretes used for underground structure
• Waterproof materials
• High temperature resistance concretes

15
Un-fired bricks
After reform

• 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
After reform
Mixture planning--- Conceive and design
Manufacture-- Implement
Testing--- Implement

CDIO Process for developing unfired brick---step 1
After reform
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
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
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.

Comments from students
After reform

• 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
After reform

• 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
After reform

• 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.

Benefits and Conclusion
After reform

• 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.
