I am a teacher in Communication and IT at Tech College Aalborg in Denmark. I worked with level design and quality assurance in the mobile games industry a few years back.
I also run the site http://www.yourgamedesign.com/ - a starting point for new and hobbyist game developers.
Teaching game production really catches the attention of the pupils. Sadly I often miss having a website for pupils who couldn't attend important lessons or need to see it all one more time. This sparked the idea of moving everything online.
You can actually kill more than 1 per second in some levels - kills in singleplayer count too and you can reload levels over and over to wipe out the locust again and again. I heard it takes 6-7 hours that way...
Thank you for this excellent article Rarely have I seen anything that can be evaluated and applied as easily as this. I wonder how well this translates to first person shooter controls.
