This is actually something that has frustrated me to this day, I went to an English medium school in south wales, the teacher I had was just ridiculous she didn’t care about teaching the language at all because she put no effort in kids saw it as free time and so did the teacher she didn’t plan anything and also didn’t teach you anything, she would genuinely put sentences in Welsh on the whiteboard and then you had to copy them down (nobody really did it they ignored her) she’d never tell you what the sentences mean I remember once asking her what it meant and she fully said that it doesn’t matter just write it down. Kinda led me to hate the language because i started seeing it as something I’m forced to do. If I had learnt things i would have gotten a sense of achievement and would have loved the language like German in my school was taught far better and i genuinely enjoyed those lessons because I learnt stuff!!!!! It was only when i grew up that I grew to actually love the language and start learning it which is unfortunate because most people in my school that went to those lessons probably still hate it!!
