The use of multiple forms of media types throughout education can help students engage better with the lesson. Not only can this be used for the purpose of enhancing a lesson, but multimedia theory can also help students that may struggle to engage with certain media types.
Carrying on along this train of thought, by expanding our fidelity into more forms of media during our lessons, students will have more ways of engaging with them. This could take many forms, be it oral, visual, tactile or something else entirely.
Some examples we could use for this would be lessons that incorporate videos alongside the actual lessons, or even potentially more interactive forms of media. A good example of this could be formats such as Minecraft: Education Edition, or other such software designed for these purposes.
