~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
With appropriate triggers "embedded" within short questions, pupils' responses could help teacher to surface misconceptions that need to be clarified.
- In the example of "Do we know these Shapes?", pupils were asked how many of each shape - Rhombus, Triangle and Circles - that they could find in the picture.
- At the end of the session, varied answers received from the class which showed that pupils did not have a clear idea on the properties of the shapes.
- Some differences surfaced includes, Are the 'triangle' look-alike shapes triangles? Some pupils may argue that, having part of the circle made up one side of the figure will mean the triangle look-alike figure has 2 straight sides only.
- Teacher can tap on the 'differences' surfaced among answers and get pupils to explain/justify their answers and invite responses from others, hence making the discussion richer. Active discussion helps pupils to clarify and correct the misconceptions, hence remember the facts/concepts better.
