Figure 9. A multiple-choice test window for the extends keyword. If the answer is incorrect,
the “Explain It” button is enabled, and the sequence repeats. If the answer is correct, the
key-in field is presented for the learner to type the item by recall
Next are presented the Stage 5
row familiarity
interface and the Stage 6
row
interfaces.
Figure 11 (top view) presents a view of the
row familiarity
interface, which is labeled Row
Symbol Familiarity in the title bar. The
row familiarity
interface is functionally similar to the
item familiarity
interface, except that the input is based on the rows of code rather than on
the items of code. Figure 11 (bottom view) presents a view of the row interface with accurate
code entered into each of the 10 rows. There are three successive iterations, or passes,
through the row interfaces. The first pass is similar to the item
interface. The task is for the
learner to enter the code accurately in rows by recall. The learner may display the row code
and keep attempting to input the row until it is entered correctly. Figure 12 (top view)
presents
a row explanation window, which displays the meaning of the code in a row. The multiple-
choice test, displayed in Figure 12 (bottom view), appears after a row is entered correctly, and
the cycle is functionally similar to the item
interface. In the second pass through the row
interface, there is no multiple-choice test, and there are no explanation windows. The learner,
however, can still display the code in a row before trying to enter it or after making an error.
Each row of code must be entered correctly by recall before moving to a succeeding row of
code. The third pass requires the learner to enter all 10 rows accurately without displaying
the code for any row. Whenever the learner selects to display the code in a row, all rows of
