Figure 6. Top view = item familiarity interface showing the extends keyword displayed and
entered into the key-in field. This is the first interactive interface in the tutoring system.
Bottom view = item identification interface showing the extends keyword displayed for
highlighting in the list of items
of the MyProgram.java file is explained, and the HTML file is taught. Students then run the
Applet on the Web.
The Stage 2 item familiarity and the Stage 3 item identification interfaces are presented
next, and these are interactive interfaces, as are all remaining interfaces in the tutoring system.
Figure 6 presents these two interfaces as they would appear for the following Java keyword:
extends.
Figure 6 (top view) displays the
