Want to study argument mapping? Read Dona Warren's textbook, Critical Thinking with Argument Mapping. And practice, practice, practice!
Computer-based argument mapping (AM) is an unprecedentedly effective teaching method. It improves many abilities, like memory , writing , and critical thinking. Here is an explanation of what AM is.
Whereas a typical semester of college improves critical thinking by 0.2 to 0.3 standard deviations, a semester with an AM-based course produces a 0.7 standard deviation improvement [1,4,5,7].
The critical thinking skills measured in this research have been shown to predict life outcomes . By improving students' abilities to reason about how to achieve their goals, and about which goals are worth pursuing, AM-based courses will help students achieve more valuable goals, from the big ones, like owning a home or being a good parent, to the small ones, like returning a library book on time .
Given these benefits, we think it's worth exploring whether widespread AM training could help with some of the social problems we face.
