Arnieboy - So true. My mum was a primary school teacher for 40 years. She used to laugh about whether she was currently in or out of fashion. Maths was one example, phonetic spelling another. She was old school and tried to stick to that but every few years she had to bend a little bit when she had no choice. Inevitably after a few years of experimentation the system always went back to the old school way again and she was back in fashion. She retired 10 yrs or so ago but as my kids are going through the system I am seeing the same cycles happening.
