As for whether the PowerPoint is last decade technology or not, well, for me, it's just one amongst many resources you can use in the class room to get your point across to the students during briefs and de-briefs. The whiteboard and whiteboard markers are still a valid resource and so too is a small model aircraft of a Cessna 172 or Piper whatever. Also useful is a cutout of the 'forward view out the window' to show the students the differences in pitch attitudes during climb, cruise and descent. Yep, call me old fashion. lol..
