one of my chemistry teachers was a “Dr”, my main recollection of him is that he appeared to have faintly dark green stubble – it could have been the light in the class room but I think we all put it down to too many chemicals!
Most of my teachers in school were not doctors, although I do remember having a biology teacher one year that did have a PhD and a physics teacher that was a PhD student while he taught at our school (tough doing both at once!)… However, most of my teachers at University were doctors!
Let’s see, all 3 of my Chemistry teachers were Doctors, and 2 of my 3 Biology teachers were too. I don’t think either of my Physics teachers were.
One of my favourite teachers (Miss Heymans) was the Biology teacher without a PhD – she really knew her stuff and she made lessons really enjoyable. A good researcher doesn’t necessarily make a good teacher!
