YABVU IMO.
I also get annoyed by this assumption that by taking them out is purely to get a cheapo Benidorm style holiday
My DS has severe SEN so the focus is more on learning simple life skills rather than a more traditional curriculum.
A while ago now, my DS's class were doing a space project whilst we were planning to take him out of school.
It was purely by coincidence, but one of the reasons we were going was to witness the final launch of Space Shuttle Atlantis at Kennedy Space centre, which we did, along with meeting a real astronaut.
The whole experience was absolutely mind blowing and is one of the best moments of our lives at this point in time.
The shuttle launches were notoriously unreliable so we were incredibly lucky that it did go ahead in the first place.
So OP, as a teacher, which do you think was more beneficial to my DS?
Sitting in a classroom looking at astronomy books or on the internet versus Actually being there, feeling the ground shake, Hearing that indescribably roar of blast off, as well as getting to talk to and ask questions of a real Astronaut, a Female one at that too, who was also a Teacher when not whizzing around in space?
To me, and my DS's very sensible Headteacher it's a bit of a no brainer really, don't you think?
Especially because my DS learns in a very visual, emotional way.
Each case should be judged on it's own merit. Not all parents are taking their DC's out to sit by a pool quaffing sangria.
