I was thinking about the IGCSE the other day – I have gone from teaching GCSE, to IGCSE, back to GCSE and now to IGCSE again and I still find myself having to check the list to see what topics are included/not included on IGCSE.
I’m a bit bemused as to why certain topics were omitted/included to be honest.
- Sets, Functions, Calculus – these are the big ones and I can see why as all are relevant for A-level.
- Intersecting Chords Theorem I feel doesn’t bring much, but it’s only a minor topic so I’m willing to let it go.
But excluded topics include:
- Exponential graphs/functions
- COMPLETING THE SQUARE??
- Gradients of perpendicular lines
- Transformations of graphs
- Equation of a circle
- Trigonometry graphs
- Scatter graphs, line of best fit, correlation
- Box plot, stem and leaf
I just don’t know what I think about it to be honest. There is one I strongly disagree with (you may have noticed which one that is…) as I think it’s such a key part of understanding quadratics. But then I suppose if you do completing the square, you should also do graph transformations to get the best out of it. It’s such a key ability at A-level though!
I’m a supporter of IGCSE in general as I think it does stretch the top end more with more problem-solving, but I wish they had kept completing the square! I know you can’t include everything, but what would you omit/include?
