There is growing recognition globally of the need to teach Critical Thinking as part of formal schooling and of its importance to the “knowledge economies” of the future. Yet international research demonstrates that without explicit instruction in critical thinking, undergraduate education often results in little to no gains in critical thinking, analytic reasoning, and other "higher level" skills.
One very effective way to improving critical thinking is through argument mapping — the visual representation of an argument’s logical structure. Argument mapping can improve critical thinking skills by offering students an opportunity to engage in metacogntive evaluation — evaluating the quality of their own, and others', reasoning.
Unfortunately, argument mapping is rarely used outside of philosophy classes owing either to a lack of instructor expertise or availability of tools appropriate to non-philosophical pedagogies. Current digital argument mapping tools are either desktop software, limiting their ability to be integrated into online courseware, or propriety and tighly coupled, limiting their access and extensibility.
