These role-plays are in zip files. Each file contains an
explanation and/or scripts for the role-play and Java code
that the role-play demonstrates. You will need the objectdraw
library for some of these.
This role play uses the objectdraw library from William's
College. However, it could easily be adapted to another
context that has graphical objects, such as BlueJ.
This is a role-play that can be used early in a course.
role-play for parameters
This role-play is designed to help the participants and
observers understand how object parameters are references
that are passed by value. There are two versions, one that
uses the objectdraw library from William's College,
the other uses BlueJ.
role-play for recursion
This role-play again uses the objectdraw library
but could be adapted. It is based on the broccoli example
from the recursion chapter of the book Java, An Eventful
Approach, by Bruce, Danyluk, and Murtaugh.
Biology Simulation role-play
This role play was developed by Steve Andianoff and David
Levine at St. Bonaventure University (see link below). It
is useful to demonstrate the relationships among the objects
in the MBS case study program. It can be used before any
case study code is examined to help students understand
the parts of the case study code.
Levine's Role-play page
David has a discussion of using role-plays and several useful
examples at this site.
