Abstract
This reflective article details the evolution of Gerald Nosich’s view of what critical thinking involves. Nosich recounts three major stages in the development of his views: (1) starting a course on Reasoning that strongly engaged students in the actual practices of argument analysis and evaluation, (2) then teaching a course Critical Thinking Across the Curriculum which called into graphic prominence other aspects of critical thinking beyond arguments, for example, observing thoughtfully and reflectively, raising key questions with respect to an issue, and discerning a common structure underlying different phenomena, and, finally, (3) realizing the power of Richard Paul’s emphasis on common elements and standards involved in critical thinking.
