I have been using APP a lot in my key stage 3 science lessons in the last few years.
I like the balance between scientific ideas, communicating in science, seeing how science ideas have changed, experimenting in science and writing conclusions using evidence. These are the things that I would like to see in the new science curriculum, and I think we get it.
I am not sure that I like the point "intrinsic nature" of variables, surely there name implies their nature? I wonder what is meant by "other factors", probably repeats and range of the variables. I don't like the use of the word reliability as it is part of the language of measurement that we have been struggling with.
I am pleased with the inclusion of the word field work, it implies that the government supports this.
I don't disagree with any of the statements in this section. Although I wonder if the sections could be better divided as it does overlap with the experimental skills and investigation section. Although I can see a rationale in making them separate as not every practical I carry out to find evidence to draw a conclusion during a lesson would be an investigation. (In fact not many are).
Again, the 2015 is more closely linked to the 1999 curriculum, but there is less detail. I actually think this is a step in the right direction, I don't think that the descriptions in the 2008 curriculum really put enough emphasis on carrying out investigations critically and what this involved. I say this because I think that working scientifically, the investigations and critical analysis of evidence, is the most important aspect of science in the school curriculum.
Here is Alessio's mind map of the working scientifically aspect of the new national curriculum.
