How did sketchnoting change your ability to recall the information you were documenting?
When sketchnoting I definitely found that breaking down the thoughts that I had in class into important bits of information was more effective. I did my sketchnote during the lecture itself and found it difficult to add things like images or little pictures throughout the note. I instead stuck to things like symbols, outlines and arrows. This would probably be better used as a studying technique to review your notes after a lecture. I am still able to recall most of the information from the lecture when I go over the sketchnote. It is also much easier to read and review a sketchnote instead of a block of text.
How would you incorporate it into a learning activity?
A learning activity that could have sketchnoting incorporated into it is a memory test. I remember in a psychology class when I was in highschool we were discussing how people remember things and my teacher had us try to repeat the information in a block of text, but we were only allowed to make a limited amount of notes. Sketchnoting could be used to make the notes and we could see the difference between how much information that can be recalled in making limited text notes and sketchnoting with the same limit of words but allow the inclusion of images and symbols that are utilized in sketchnoting.

I think that sketchnoting is extremely useful for visual learners and for simplifying notes on topics that have way too much information to write down, like biology and psychology. I have been using sketchnotes for a very long time apparently as i have always done my notes this way!
