E-learning Essentials Guide was developed for course developers and training decision-makers who are new to e-learning. The guide aids in the creation of quality e-learning by identifying key instructional components and summarizing what they are, why they are important, and how to use them most effectively. At the end of the guide, you can find additional resources that were consulted to create this manual.
