Presentation Transcript

  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.”
