Comments from those who selected Cmap as one of their Top 10 Tools

“Excellent for creating concept maps and visualizing my students process of gaining and retaining knowledge” Santiago González Chávez, 2015

“When I’ve got some complex ideas to sort out and simplify, I quite often turn to CmapTools. This is a concept mapping tool that allows any concept to link to any other concept, along with linking phrases. Very quickly, a map can become too complex. But then that forces a thought process to simplify it down to its essentials. I often go through that process when preparing presentations or learning materials. It makes sure you only include detail that is relevant”  Mark Berthelemy

” I use concept mapping for planning, organizing topics, and to see how ideas connect to each other. When teaching, in order to evaluate learner’s understanding, I require her/him to produce a CMAP of how course components relate.”  George Siemens
