I had about 8 elementary school students, who were KSP first-timers, run the first three KSP tutorials today.
Short story: With the instructions up in front of them, the students kept asking me what to do next, because they were lost.
Long story: The tutorial dialogs are way too verbose - or in the case of my students: TLDR.
WHAT TO DO should be highly visible, and easily distinguished from descriptive or ancillary text.
I found having to set the parachute parameters on the first rocket you build to be unnecessary and confusing; my students couldn't figure it out at all.
I experienced this with both middle school students in the Endeavour Space Academy last year, and elementary students today.
