If you’re not careful, an eLearning lesson can quickly devolve into an “information dump” where learners are barraged with a huge pile of data with no opportunity to apply it to their everyday lives. This often happens when you have an overly price-conscious client who’s looking for a lot of production on the cheap, or a client who has not filtered out all but the most essential and relevant content from the course.
I recommend that for every five minutes of content you should have some sort of interaction where the learner gets to do something to apply what they have learned. These can be something as simple as a multiple choice question or a drag and drop interaction, or you can create a branching real-life scenario. There are all kinds of interactions which will break up the lesson, and help the learner to think about what they’ve learned instead of just glazing over as the information flies by them.
