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

The Learning Cycle Exploration Dialog Application

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,

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

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

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.”

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.”

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.”
