The image and word could form a stronger image in the memory than mere text, such as this.

In my personal experience, I remember most vocabulary when confronted with a real life situation which is very easy to recall later. I remember grammar rules better when explained with diagrams. Not everyone will find these methods beneficial, but those struggling with text books could.

In the same way, videos and cartoon strips could provide very useful learning aids. As well as a real world situation such as a phone call asking you to do something specific.
