The level of interactivity used in a course has a direct correlation with the time to develop and the cost of development. While having a high degree of interactivity adds to the interest level of the learner, too much of it can sometimes backfire as the core message tends to get lost.
Our team agrees with the sponsor and the client team on the level of interactivity in the courseware and document the agreement in the project management plan. Below are the guidelines for the level of interactivity.

"Level 3 is a preferred level of interactivity because it optimizes the trade-off between active learning and time to develop"

Level 1 - Passive. The learner acts solely as a receiver of information. The learner progresses linearly through the course reading text from the screen, viewing video, or listening to audio. This level is highly discouraged.

Level 2 - Limited interaction. The learner makes simple responses to instructional cues. Examples include multiple-choice or true/false questions. If this level is used, as a rule of thumb the learner should have an interaction every four or six screens.

Level 3 - Moderate participation. The learner makes a variety of responses using varied techniques in response to instructional cues. Examples include assembling a model or diagram from available parts, drag-and-drop, or answering multiple choice questions about realistic scenarios. This is a preferred level of interactivity because it optimizes the trade-off between active learning and time to develop.

Level 4 -Simulation & game based learning. This level involves high degree of interactivity wherein the learner is provided with extensive simulations and the core message is delivered through the use of complex games to keep the learner motivated. This level almost borders on entertainment and the time to develop is longer.
