** Based on a representative sample of 186 Year 8 students in May 2000

NOTE: Students found each question easier in the online version than the previous print version, especially for question c). This is almost certainly because they can compare the dragged image with the given one, and become less reliant on visualising. 

Diagnostic and formative information: 
  Common error Likely reason
a)
2 (online and print)

 Confuses rotation with reflection in a vertical line.
Confuses quarter and half turn.
c)
1 (print)
cat-patch-a.png
 Confuses translation with reflection in a vertical line.
d)
3 (print and online)
 Confuses clockwise and anticlockwise and doesn't see a reflection is also needed.
