This document discusses creating online tutorials using screencasts for an online class. It explores how librarians typically teach using techniques like scaffolding, modeling, and connecting new concepts to prior knowledge. It also examines learning theories like behaviorism which focuses on stimulus-response learning and cognitivism/constructivism where learners actively construct their own understanding. The document questions how to determine learning goals for tutorials, how to assess if users attain the goals, and how to understand why certain teaching approaches in screencasts are effective.
