Example #3: This map is from a course called “Developing
Performance Aids,” created by Peter Pipe. Here the meaning of
the horizontally dashed line is: The units below it are to be
read, studied, and discussed; but because they are informa-
tional only (e.g., Module IN-2), there are no performance
checks (criterion tests) associated with them.
The placement of modules DT-1 and ED-1 on the map
expresses the best wisdom and experience of the author and
says to the student,“While it is true that these modules have no
prerequisites and may be studied at any time, you will find it
more productive to study them sometime after you have com-
pleted module PA-1.” Why then didn’t the author draw a line
between PA-1 and the other two modules? Because he didn’t
want to falsely suggest that PA-1 must be learned before DT-1
and ED-1 can be learned.
