Using second hand data and recording results
Further reading and comment from the Year 8 text book http://lessonpeer.com/drhillteach/Using%20second%20hand%20data%20and%20recording%20results.MP3covering second hand data (all information you don'r directly observe). The book takes an interesting stance that it is unethical to pretend to take someone else's data. Basic citation is a quality control measure developed by science and almost automatically puts down textbooks with out citation as poor quality.
Chapter 1 section 3 deals with recording and presenting results. I think there was a missed opportunity to make the distinction between graphs (connecting two continuous variables) and charts which show the relative magnitudes of different types with in a class (object oriented programming lingo here). The text committed the horrible educational mistake of saying a hypothesis should include what theory you feel a positive result will show. In my experience: If you are not switched on enough to pick up the problem in setting up confirmation bias, then reading sloppy thinking will probably be evidence that this is not an issue.

I read and comment from our Year 8 science text book. It is good training for me before my big operation, but will students benefit by listening to it? Time will tell.
