We thank the University of Michigan's Language Resource Center and Department of Near Eastern Studies for their help in preparing the showU demo materials, including creating the RealAudio® sound files, supervising the preparation of the Hebrew language story, and providing invaluable guidance in improving the pedagogical value of the exercise.  In particular, we thank Reid Paxton and Philomena Meechan for their support and guidance of this work, Edna Amir Coffin, Doron Lamm and Ilan Rosenberg for their assistance in Hebrew translation, and Ilan Rosenberg for narrating the story.

An English translation of the story for this exercise is available here.  The objects, in order down the list, are:

file cabinet
telephone
chair
computer
papers
mug
book
rug
stool
diskette

The exercise expects one computer to be placed on the empty table in the room with the red door.  The computer is the fourth item from the top of the list.
• Begin by doing nothing -- just click the compare button at the bottom right of the applet.  You will see a message, and the corners of a "hint" rectangle marked in red.  (The corners will briefly flash yellow to catch your attention.)  Click the return button (it replaced the compare button) to try again.
• Put one computer on the table with the soda can, and click the compare button.  You will see a new message, and the computer will be surrounded by a red box.  Click the return button to try again.
• Put one or more extra computers in the scene, and click the compare button.  You will see a new message, and each computer will be surrounded by a red box.  Click the return button to try again.
• Clear the scene by clicking the eraser.  Now put a computer between the tables.  Click the compare button.  You will see a new message, and the computer will be surrounded by a red box.  Click the return button to try again.
• Try your own combinations.  When you click the compare button, look for a down arrow at the bottom of the message area.  If you see one, click on it to see additonal messages.  There may be several messages generated for any submission, depending on the complexity of the exercise and the number of errors.  Here, there are many other objects specified by the exercise, so if you only place the computer, many other error messages will be generated.  In each case, click the return button to try again.

The exercise expects two diskettes to be place on the empty table in the room with the red door.  The diskette is the last item on the list.  To simplify your review of the error messages, click the eraser and then place a computer on the empty table so that no error messages about the computer will be generated.
• Begin by doing nothing else -- just click the compare button.  You will see a message, but no region will be marked.  This is a result of choosing a certain design for the writing the feedback rules.  It may be preferred for certain types of exercises.  Click the return button to try again.
• Put various numbers of diskettes around the scene, click the compare button, and see how the objects are marked with surrounding red boxes.  Click the return button to try new arrangements.

Try out some other parts of the exercise (read the English translation to understand what is required.)  A variety of techniques have been used for designing the feedback for different objects.
