Exercise 8-4
Exercise Title: One-Way and Two-Way Communication
Purpose: To demonstrate the advantages of two-way communication over one-way communication.
Summary: This is an exercise that is virtually always interesting to observe and provides rich data for
discussion. You will need a set of Tinker-Toys or Legos for this activity.
Before class, build a structure out of Tinker-Toys or Legos of moderate complexity. We have found
structures using 30–40 “sticks”, “wheels”, or “building blocks” of varying sizes and colors work best.
You may choose to make your structure either symmetrical or asymmetrical. It probably should not
represent an actual object (e.g., a car), and it is best if your structure uses a variety of pieces. When you
bring the structure to class, be sure to keep it covered.
The task is for the leader to describe and for the follower to build a structure identical to the one in front
of the leader. The leader should proceed at as rapid a pace as possible, mindful that the task is to direct the
follower to precisely duplicate the model structure. Tell them both from this point on that they may only
communicate with each other according to the following rule. In essence, the follower may not
communicate with the leader in any way whatsoever. This includes not only direct queries or
acknowledgements, but also any other sort of information such as laughs, grunts, moans, sounds with the
pieces, etc. Communication is to be one-way only, from the leader to the follower.
You may stop the exercise either by setting an arbitrary deadline or by waiting for the leader to complete
his or her directions (obviously this must be totally independent of any knowledge about the actual state
