Bad teacher's

Yes Day6, a good point to remember teachers who encouraged us. the OP though is about bad teachers.

In a spirit of fairness, I remember Miss Slater who taught us history from 12 - 15 when I moved (again). She nurtured by existing fascination with history and her lessons on the Empire, East India Company and the slave trade influenced my politics. Thank you Miss Slater

The grammar school across the road from your secondary modern was not the one I attended then!

The teachers at the grammar school I went to made sure we all realised just how stupid we were. Any ambition other than becoming a teacher was scoffed at.
The last thing I wanted to do was become a teacher and end up like one of them.

Callistemon, I was lucky at that school, it had an inspirational head. We had houses, competed in various sports events and choral speaking competitions. He was a Gilbert and Sullivan fan so we had a production every year, everyone involved.. we were taken to the ballet,to Shakespeare and on trips to Europe. We also took O levels.
Needless to say, many of us went on to university as mature students

Let's not forget that as children we weren't all angels. I remember we had a young French teacher we played up appallingly. It was a co-ed school but he had one lesson where he just had girls (think the boys were in PE). We specialised in distracting him by asking silly questions which he tried to answer so earnestly. We also sometimes asked things just to see if we could make him blush. Poor man!
