Having seen my share of eLearning courses, built a few, and reviewed quite a few, this link was interesting to read.
The Back/Next navigation, which relegates interaction outside the content has been done to death, almost like PowerPoint. The learner is a passive consumer of the content – the said interaction is no interaction, but a chore to push the passive state of content from one screen to another. There is no excitement in the “interaction” and the said “interaction” is in a frame that contains the interaction.
Instructionally, this imposes a way of navigating on the learner, that leaves no scope for discovery or exploration. More often than not, moving media (animations, video clips) embedded in the content is often passed for interactive content. This is, at best, active content.
Not all samples in this link are the best in terms of instructional design, but they definitely make a case for breaking away from frame-based navigational interaction.
