"Most instructors notice places in their courses where students find it difficult to learn. Decoding the Disciplines holds that these stuck places, or “bottlenecks” to learning, mark the important ways of knowing in a field. By “Decoding” what an expert does so that they do not get stuck at the bottleneck, we can spell out the expert’s mental process, the “critical thinking” of a discipline. Decoding the Disciplines is a theory of pedagogy with principles for identifying bottlenecks and decoding tacit disciplinary knowledge. With expert tacit knowledge “Decoded,” we can make it available to students."
