After PiXL conference yesterday I have been thinking about exposing students to mark schemes and getting them to be in the shoes of an examiner more often.
Here's my dodgy solution to a CP1 series question, i'll give it to my class to mark and spot the mistake(s).

There's water trapped in this train window, and here's how it sits when the train
• moved at a constant speed
• accelerated out of the station
• decelerated coming into the station
Which is which? How do you know?

Its interesting to me that in about 3 clicks on my phone I can learn that the new pope did a maths degree and was the editor of his college yearbook (which placed 2nd in a yearbook competition)
I'm not saying I'd like this information to be more difficult to find. Just interestingly accessible.
