Long description

Photograph of an A3 paper mind map using a tricky topic structure template. In the centre is a box containing the tricky topic, ‘optic ray diagrams’. Connected to this block are four stumbling blocks, ‘what is a light source’, ‘scientific language and use of key words’, ‘rearranging equations’ and ‘what do drawn rays represent’. Around the outside of these stumbling blocks are problem examples such as ‘directionality of rays’ and ‘inability to direct light rays’.
