♦ children's written record ♦ practical test (ie: build something) ♦ children's self assessment ♦ project report (home/class) ♦ diagnostic test ♦ skill test Self assessment could be generated as suggested in this picture, but there are other ways and some student self-assessment tools are included at the end of this article. Work in pairs and carry out a colour vision evaluation using the City University colour vision test on each other. Make a note of whether any targets are identified incorrectly and fill out the score sheet. 3. Farnsworth D-15 colour vision test. Introduction.
