"Sketchnoting, in its purist form, is creating a personal visual story as one is listening to a speaker or reading a text. I also believe the interactive notebook, which includes the process of taking "regular" notes" while listening to a speaker and later creating a sketchnote of the text notes, would also be considered sketchnoting. This page will provide links, ideas, tips,and research evidence dealing with the power of sketchnoting. If you are looking for a book on the topic, the seminal work is this book by Mike Rohde. "
