Making it a video would just decrease the reading levels over time wouldn't it? Also this may sound bad, but there isn't much content out there a 6th grade reading level can't decipher. Instructions aren't about breaking down what meaning they really might have had. I don't need to figure out the underlying meaning of animal farm during "loosen 6 10mm lugnuts" or "enter dsregcmd /status and check the provision status at the bottom.". With each line being discussed I don't need to examine the underlying text. Most everything in life is able to be done at a reading level of 6th grade.
Wish it were higher, but that isn't our biggest failure in education right now in my opinion.
