After seeing Geoff Neuss' marking exercise for chemistry, I thought I would make something similar for physics. The idea is that you mark the sample investigation using the Google docs form then compare your scores with other teachers by viewing the form statistics. Comments can also be left in the usual comment boxes. There are now almost 500 IB teachers using this site, if a good number have a go the results could be significant. This is only available to subscribers.

Investigation marking exercise

Note that the report used is an old design lab however it is fine for this exercise.
