On-Line Drill and Examinations
If the more traditional computer-assisted instruction tools of
tutorials and simulations have been given new life in the
multimedia environment of the World Wide Web, traditional "drill
and practice" exercises and multiple choice examinations can
also be revitalized on-line. Such on-line tools can certainly
reach larger audiences than comparable disk- or CD-ROM-based
software tools.
Again like on-line tutorials and simulations, on-line drill and
examinations must implement the best practices of traditional
CAI for effective presentation on the Web. On-line "drill and
practice" should be used to reinforce previously learned
information, never to learn new information. These exercises
should offer a randomly generated series of questions taken
from a larger question bank. In this way, the exercise could be
repeated without covering the same questions. Each question
should provide maximum feedback that corrects the mis-logic of
wrong answers and reinforces the logic of correct answers.
Navigation between questions should be controlled. Wrong
answers should receive feedback and navigate back to the
original question. Only after a correct answer and feedback
should the student proceed to the next question.
On-line examinations -- while not providing the depth of
feedback of "drill and practice" exercises -- should be graded
automatically and should return a "marked" exam page. This
"graded" page should redisplay all of the questions and offer
a cumulative score, display some sort of graphic indication of missed
questions, and note the correct answers to all questions. A
tracking database might be used to record student performance.
