You also have the option of presenting opportunities for practice in the form of study questions or introductory queries. Allow readers to guess responses, and provide the correct answers as one means of feedback. These strategies engage the learner in ways that move beyond scanning or reading passively a series of slides. Even when this is accomplished in a linear process through PowerPoint, techniques such as these also instill in the learner a sense of control and self- pacing, which are traits that are important when designing computer-based learning.
