I recently heard about this clever system of marking essays written by primary and secondary students in the UK. With just a few tweaks, I could easily see this system working very well for grading translations in an academic setting.
Teachers are confronted by two essays on their screen, and only have to choose which is better. The essays are anonymous and (as far as I can tell) teachers see essays from all over the country, not just their own class. The software then statistically devises a mark for each essay.
I cannot stand grading essays and this system seems so much easier on the brain. I’m all for it!
