Stated simply, mindmapping is a technique that uses graphics and text tied together in an effort to increase improve your retention and idea generating capabilities. I know – it sounds like a really “big ask” but bizarrely enough it works!
An extremely useful tool from a brainstorming perspective, having a mind map on the board and multiple parties “throwing” ideas to link to/from that map makes for a very interactive and useful exercise.
Having a simple picture with all the different links to and from it makes it really easy to see some relationships that you wouldn’t have guessed at also to see some extra links that can take you in many different directions.
While the research is still out on its actual impact with regards to study notes, there have been studies that demonstrate a significant impact on memory recall. As with most forms of studying, the act of writing things down improves retention vs. just listening. If you follow all of the mindmapping guidelines and use images to represent ideas with colour also, this is only further enhanced.
