Argument mapping is a technique for visually mapping out arguments and the relationships between different ideas. It can help clarify complex debates and make the various positions and supporting evidence more understandable. Research suggests it may improve learning, though not always. Tools now exist for mapping arguments on the web in a collaborative manner. This allows learners and analysts to jointly build argument maps by directly annotating websites. Mapping has been applied to topics like climate change, science debates, and political discussions to untangle complex arguments and analyze different perspectives.
