Beth Still from the Nebraska Educators Network follows Will Richardson on Twitter, which had a link to this great site for chemistry teachers: The Periodic Table of Videos – short videos about each of the elements of the periodic table. So I’ve been back to Twitter and found some friends, and now I think I understand better how it works. It seems nothing I try really takes off the first time – I need a few months to let the idea brew – perhaps until I see a purpose for it – and then go back to it. It just seems to reinforce that learning is best done on an ‘as-needs’ basis. Make it relevant, authentic and interesting.
