A dismal introduction I know, but my first posting will have to be about exams, since I have been almost wholly occupied with grading both AP and IB papers over the past month. While I prefer teaching (economics and math), I have to admit that I am always thrilled to have the chance to mark external tests. I open each paper expectantly—never knowing what might be inside—and it’s interesting to compare and contrast responses.

Indeed I always learn a lot while I’m grading; at the risk of boring you, may I pass on the following few points:

1. Every word in a question is significant; nothing should be ignored.
2. Keep your answers straightforward: 1.If in doubt confine yourself to the short run (unless it’s an economic growth question); otherwise you are likely to end up with a convoluted response, which could go on for ever! 2. Don’t ever contradict yourself; the examiner will think that you’re hedging your bets. It’s preferable just to pursue a consistent line of reasoning.
3. Don’t use vague terms or statements that are unsupported. Words such as “productivity”, “profits” and “efficiency” are often used glibly and inappropriately. The test taker consequently appears to be gabbling. Make sure to cite actual policy tools, not just general strategies, such as “expansionary”.
4. When drawing graphs: a) Every axis and curve must be labeled. (If in doubt put P on the vertical axis and Q on the horizontal). b) Never indulge in double shifts of demand and supply unless two events have happened. c) Clearly show the old and new equilibrium points with the use of dotted lines to the axes.

I really should have waited until next year to write the above, but by then I might have forgotten what seemed most important while marking. In the meantime I will take to heart what I have learnt from reading many student responses to AP and IB question; in particular I will try not to gabble myself while teaching.

She has engaged in various occupations (development economist, mother, researcher & writer) since first leaving home (Britain) for Tanzania in 1974, but teaching is her favourite activity, along with reading, making timetables and skiing.
