In order to be explicit about what teaching entails I modified the diagram. I changed “Teaching” to “Instruction,” but I continue to use the initial description: “Amount of support needed for new learning to occur.” Sometimes that means a demonstration, and other times it means an activity that allows learners to engage independently in a worthwhile learning task. Sometimes instructions falls somewhere in between.
Instructional decisions depend on the plans the teacher develops as a result of his or her evaluation of assessment data. That was the reason behind the change – to enable pre-service educators to recognize the role of each element in teaching and not just associate teaching with instruction. And so far the change seems to be working.
