variation-theory
Apply variation theory of learning to structure instructional content using contrast, generalization, and fusion patterns. Variation must target the critical aspects of the learning objective. Use when writing educational materials, explanations, tutorials, literate programming documentation (.nw files), or when user mentions variation theory, learning theory, pedagogy, or critical aspects of learning. Works alongside the literate-programming skill for .nw files.
try-first-tell-later
Structure educational content using try-first-tell-later pedagogy where students predict, attempt, or reflect before receiving explanations. Creates active learning through cognitive engagement and variation theory's contrast patterns. Use when writing educational materials, designing exercises, creating lecture notes, structuring tutorials, writing teaching examples with LaTeX/Beamer, developing problem sets, or when user mentions try-first, predict-first, productive failure, Socratic method, question-before-answer, exercise-driven learning, or inquiry-based teaching.
