Figure 10. The item interface with the extends keyword typed into the key-in field. If the
input is correct, the “Show Java” button is enabled for the next item to be learned. If the
input is incorrect, the key-in field is cleared, and the “Show Java” button is enabled for
the learner to repeat the sequence of steps for that item
the interface are cleared, and the learner starts to enter the code again from the first row. This
continues until all 10 rows are entered correctly without the learner displaying the code for
any row. Buttons to control the actions available on the row interface are selectively displayed
to the right of each row.
The Stage 7 program interface is presented as the final interactive interface. In this
interface, the learner enters the entire program with a relaxed format. The discipline of the
previous format requirements is eliminated, and the learner may enter the code in any format.
Figure 13 presents a view of the program interface, labeled Text Editor Emulation in the title
bar, with correct code in the text window.
If the code is incorrect when submitted for evaluation, the learner may attempt to make
corrections and submit the code again. If the learner is unable to find and correct the error,
the Review may be selected. This choice sends the learner back to the third pass of the row
interface, and the tutor progresses again from that point. When the learner completes the tutor
in the classroom, the student exits the tutor and awaits additional instruction in the
subsequent class period. Other learners may progress to information that explains how to
compile the program, write the HTML file, and run the Applet.
