In-Depth Information
Figures 1, 2, and 3 present detailed performance data for all three learners, respectively,
across the five successive session occurrences. Each figure is a cumulative record of all
interactive events that occurred during performance on the item interfaces and the serial
stream interfaces. The day of each session is presented relative to the first session. The
figures show that S-3 had the first four occurrences spaced apart seven days, and S-1 and
S-2 had some session occurrences that were somewhat less than seven days apart. The
performance data did not support learning outcome differences that could be attributable to
these small differences in occurrence intervals over Sessions 1 through 4. The figures also
show that the fifth session, which involved a fifth exposure to the tutor, occurred approxi-
mately three months following the fourth session for all learners.
The primary data of interest are
Item Correct
and
Stream Correct
. These entries refer
to the correct input of individual Java items on the item interface and correct input on the serial
stream interface, respectively. The serial stream interface required entering up to three
successive items of code as a unit. The
Observe Item
dash reflects the selection of a pop-
up window displaying the correct item input. The interpretation of these figures and those
below would be assisted by the reader's use of the tutoring system.
