Crossword software: Consolidating learning 

Physics teacher, Ian Yems, describes how his learners construct crosswords as a way of revising their knowledge of scientific terminology. Software for creating simple puzzles is available from a number of sources. Ian downloaded ‘Hot Potatoes’ from http://web.uvic.ca/hrd/halfbaked/ to create the crosswords. 'Hot Potatoes' can be used free of charge by educational institutions provided they make all their pages available on a public website.
