1. How is this sketchnoting technique different to the traditional note taking?
I think that the difference lies mostly in the way we revise the notes. Sketchnoting makes it easier for us to summarize an entire idea which helps us to easily memorize the whole point of the subject. Traditional note taking makes it hard for us to find the core idea of the subject unless we read the whole text, while sketchnoting will simply present the main idea with visuals.
2. How does this visual approach facilitate communication of your ideas? Conversely, how does it prevent it?
For starters, I think the visuals incorporated with sketchnoting helps us memorize the ideas much more effectively and easily. As they say a picture worth a thousand words. In our case, a sketch of an idea is worth a couple of hundreds. Sometimes a simple sketch can hold a lot of meanings that our brain can interpret without wasting our time reading an entire paragraph. All I am trying to say is sketchnoting is much more faster at presenting an idea than simple writings.
However, I think the down side of the whole process is if we missed out the point or idea of the given subject, it will be hard to remember what the subject is all about. Or if we misrepresent the idea due to underdeveloped sketching vocabulary, then that would be a problem.
3. Personal challenges as a sketchnoter.
I reckon the hardest part for a sketchnoter is during taking notes of a talk or a presentation. Personally if I take the TED talks as an example, I personally couldn’t start sketching anything as I was busy trying to grasp what is the whole point of the talk is all about. I cannot gather my thoughts until the talk is over, because we are unaware if the presenter has anymore ideas to share, before he concludes his talk.
