1. Engineering Materials Presented By: Brad L. Sandrock Professor CCAC-South Campus

2. The Learning Cycle Exploration Dialog Application

3. Exploration Discovery by student of basic concepts of new theory Instructor must lead and draw theory out Not high priced equipment – some examles: paper clips, file, paper punch, wire, marshmallow,

4. Dialog What used to represent the lecture for a course I use a flip chart, overhead, video clip, occasionally power point presentation Lots of discussion Not held in traditional lecture setting

5. Application: Just as implied - it is the application of the exploration and the developed theory Brings concepts together Still is very “hands on” Much like the traditional lab activity

6. Comments from Students; “…method teaches you problem solving skills…you work side by side in a team environment…this is the way that it works in the real world.”

7. Comments from Students (2); “…the method combines theory with experimental work…it gives an in-depth understanding of the course…the course was more appreciated, exciting and worthwhile.”

8. Comments from Students (3); “I enjoy the hands on activities. The exploration approach was used in hardness testing…I feel that this approach was an effective way of introducing a new topic.”
