Concept maps illustrate a topic that is guided by a focus question. It is generally best practice to brainstorm the relevant concepts first to create a list.
The benefit of concept maps are that they support learning through augmentation into existing knowledge and frameworks, and therefore build stronger memories than rote learning.
From there, they can be formed into a map using links with effective descriptors. Cross links between concepts often represent the most creative thinking.
Concept maps are depicted hierarchically, with general statements at the top, with specificity growing downwards.
Mindmaps commence at a central point and can diverge wildly through brainstorming. They are not designed to answer a focus question.
