Exemplars (from the NaCCA curriculum)

Group work/collaborative learning: Group learners to discuss and tolerate each other's views on heat treatment of plain carbon steels using video. And to describe the heat treatment processes. Assist learners to use the iron carbon equilibrium diagram to explain the behaviour of plain carbon steel when heated and cooled.
Problem-Based Learning: Learners investigate the conventional technique for quenching a plain carbon steel when heated and report to the class

Assessment (2.2.1.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall; Level 3 Strategic reasoning; Level 4 Extended critical thinking and reasoning.
