This exploratory project involved the design and implementation of an interactive self-paced course to teach the principles of Ohm's law. The course consists of approximately 26 base screens of text, narrations, graphics, quizzes, and interactive flash simulations.

The purpose of the project was to calculate approximate instructional hour-to-development estimates using our recently developed authoring tools.

In the first iteration, the two hour course took approximately 20 hours to produce for a development ratio of 1:10. This included the addition of text, graphics, quizzes, and narration. In the second iteration, five or six interactive quiz sections were removed and replaced with Flash simulations. The final development ratio was approximately 1:27.
