Different ways of presenting courses for different learning styles, e.g. for #itsecurity:
This course is created with comic figures on a dialogue-way
This course is made with a lot of available videos (visual)
One could also include "podcasts" in each of the courses above... and NOT to forget the "Curation" which could get used by the learners to organize themselves their interests on a certain Topic which they need to learn and which they want also to learn ...
Also PowerPoint presentations and a lot of new online tools make it more interesting for learners to get the maximum of needed information by being engaged and also having some fun to learn...
