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.”
