Hi guys, I've been teaching the Edexcel course for a few months now and I am just about able to get my head around teaching the Controlled Assessment part of the course, but trying to teach revision without a text book is leaving me unsure of how much content to teach and from what point of view. I have been using the specification but I am a little uneasy about teaching students the content I know in case it is not the 'text book' answer. I learned how to do things slightly differently from how it is stated in the Heineman textbooks that my school has, but this only gives you so much info. I contacted Edexcel and there are no courses available; I am not sure how willing my school would be to put me on one as I am only a supply teacher. Has anyone been on a course and learned about teaching nanotechnology, smart materials etc? The resistant materials text has proved useful in helping with teaching sustainability but other than that I am using bits and pieces of a range of revision guides. I am worried about teaching my A* students the wrong things and they miss out on the grade. Any suggested resources would be greatly appreciated!!
