Practice (Continued)
Here are key points for demonstrating and providing practice for
Practice for
procedures.
Procedures
Write the name of the procedure as a lead-in to the steps.
Show a demonstration of the procedure.
Include all display changes, auditory tones, control inputs, etc.
If a step involves a decision, state each decision as a separate
step.
For complex procedures, progressively list each step as it is
demonstrated or performed. (Steps should be parallel and in list
form.)
Provide aided practice as part of the presentation segment.
If there are common errors in performance, provide this
information after the student has completed the practice
exercise.
Use the name of the procedure as an action prompt to initiate the
practice sequence.
The action prompt does not name the step to be performed. This
feature should be found in HELP.
Use the same location, color, and font for the action prompt.
(Example: lower right corner, cyan, and BOLD). This
combined
set of cues will make it clear that an action is required.
Confirmation of a step completion is essential to good interface with the
Step Completion
student. The following items are characteristics of a step completion:
Provide progressive confirmation of each step as it is
successfully
completed.
Progressively list each step as it is correctly completed.
Provide a procedural help when the student gets stuck.
Provide Help icon for student to voluntarily select assistance.
Provide Help when student makes a number of incorrect
inputs(we suggest two).
Automatically clear the Help when the correct input is made.
