Poster: Alternative Assessments #ViCEPHEC17

This is my poster for #ViCEPHEC17 on a range of assessments through 3 years of the chemistry curriculum. It was a surprisingly difficult poster to put together as there was so much I wanted to include. In the end I focussed on the general skills developed rather than the specifics of each assignment.

One of the highlights of these assessments is getting students to create ‘What Am I?’ puzzles. This started as a part of this blog where I’d post the chemical components of everyday items and readers had to guess the item. Since running this as an assessment, I’ve hidden those blog posts. The students have to decide on an everyday item, investigate the chemical composition of it, draw the compounds using ChemDraw and make it an appealing single page graphic. The purpose of the first page is to allow the reader (that’d be me) to guess the item. I’m getting very good at identifying various body sprays by chemical structure. On the 2nd page they should indicate what the item is, and briefly outline the purpose of each chemical in that item, finishing with a reference list.  Should you wish to play, here is the What Am I? Variety in Chemistry Education Edition:

Below I’ve listed the key chemicals found in a common thing, which may be slightly UK-centric.  I’ve drawn the chemical structures of principal components where simple and appropriate; given the E number or CAS number (however tempting Sigma-Aldrich catalogue numbers would be) if no simple chemical structure exists for an additive; and given the chemical formulae or name if neither of the above make sense.  See if you can guess what this is!  If you guess on Twitter (@kjhaxton), please DM your guess so others can play.

With respect to the other assessments I mention, I have presented on some of the elements before so there are a couple of slide decks for further info.
