Ah, yes, Head First books are great. I worked briefly at Manning with one of the creators of that series, Bert Bates.

Oh, you know the NumberPhile channel on YouTube? I often see in their videos how they represent information on multiple pieces of paper. I just got the idea. Suppose if I were to write a book, I can first make a video presentation somewhat of a mix between slides and NumberPhile videos and then port it to a book. I think that could work.

But in general, this might work better with an online digital book. Because I could use one frame to show three slides and show some animation.

P.S. just remembered an example of an interesting book: - Beginning Elm

I completely agree Margaret and I think you have all the important points covered. There have been some studies done on how visual aids can enhance learning, so I am definitely all for them - in fact I think they are more important and relevant now because years ago they weren’t as easily incorporated (either due to cost or device limitations). It is also something YouTubers and others using video formats are making the most of.

I’d love to see more traditional book publishers (like PragProg) adopt and lead in areas like this actually - where cutting edge learning technique are used to super-charge the learning experience
