Exemplars (from the NaCCA curriculum)
Experiential Learning, Talk for Learning, Group work, and Building on what others say. Learning Experience: Learners in mixed-ability identify the maximum and minimum values of the trigonometric graphs. Activity 1: Turning point of trigonometric graphs Learners in groups explore the turning point of trigonometric graphs. - Learners observe that when the curve opens upwards, the curve has a minimum value. - Learners observe that when the curve opens downwards, the curve has a maximum value. Activity 2 Sketch the trigonometric graphs. Learners in groups create and sketch the trigonometric graphs and identify the minimum and maximum points. Teaching and Learning Resources: - Scientific Calculator Assessment (3.2.2.AS.2). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding.
