Admittedly even the soaps from back then looked a lot cheaper than they do now, compare the look of the studio scenes on Corrie or EastEnders from the 80s to now. I imagine the old tubed cameras and the bright lighting needed to get a decent picture from them didn't help. Modern cameras and ligting are much improved.
On screen production values certainly increased as the unions became weaker and the technical cost of producing television reduced. Presumably a sizeable chunk of the money saved ended up on screen.
The unions also at times refused to light sets in a dramatic way, saying the camera pictures wouldn't be as good. Hence we get supposedly atmospheric Dr Who episodes looking like they are flood lit.... but no picture noise so go unions!
The first series was networked for ITV by Yorkshire if memory serves me correctly. A second series was made but not networked, I think more for International use. Some ITV regions did show that series, Granada ran a couple of the episodes on a Saturday afternoon at one point. Difference between The Baldy Man and Mr Bean was that the latter ran as specials where as Baldy ran as a whole series, plus I think Mr Bean had finished for good by this time too. (And Mr Bean was funnier obviously.)
Take into account that the heyday of BBC / ITV schools programmes was before the National Curriculum so individual schools could set their own curricula and teachers cherry pick whatever programmes they wished to show to the kids.
I have wondered if certain schools programmes were more popular with out of school viewers than with schools. There were many people who watched schools programmes outside of school.
It was more a case of there being nothing else on, than a determined viewing choice of education over entertainment - as I remember it.
You were either at home off school sick, or where the school terms where out of sync with the rest of the country, and schools programming was still airing.
So, it was either 'television for schools and colleges' or the BBC/IBA channel 4 test cards and some music.
We watched very little TV at school, so most of my experience of ITV and BBC Schools was watching when off school for whatever reason. Certain episodes of say, Good Health were always screened during the half term holiday and these tend to be the ones most people I have spoken to remember
I'm sure schools broadcasts had loyal viewers in square eyed housewives, the unemployed and shift workers. There was no Jeremy Kyle or This Morning back then!! For a long time it was a case of choosing between schools programmes on BBC1 or ITV, or the testcard on BBC2!

I could tell the time, and had my own watch at the age of 4 thanks to the BBC 2 continuity clock, even though all I saw it displaying was 11am before Play School, and from 10:28 counting up to 10:30 ahead of 'Service Information for the Radio and Television trade.
