Two small things but really made a difference.
My youngest son is an introvert, which I didn't realise when he was only 5! His primary teacher told me that sometimes he would crawl under the big table, right into the middle and spend some time just sitting there. She figured that he just needed some time to himself and let him do it.
Now he is (much) older I realise that he probably found all day in a class of noisy kids overwhelming and needed some time out. No other school problems but I think her understanding made it bearable for him.
My middle son always struggled with school, from day one. He was very intrinsically motivated, stars, charts etc. meant nothing to him but he loved to learn if it was what he wanted to learn. What a pain for teachers. One of his primary teachers told me she'd worked out he came to school to see his friends but went home to learn.
As he got older the situation didn't improve. He wasn't disruptive, just wasn't there if you see what I mean. I remember one parent/teacher interview in particular where the teacher said "Ah yes, your son. Never going to be a high-flier, is he?" Very discouraging having him written off like that.
One day, out of the blue, I had a call from one of his teachers who said he just wanted me to know what a pleasure it was teaching my son. Every few years, he had a pupil come along like my boy, who sees the world in a different, original way and he found them a real pleasure to teach. He hoped I appreciated my son and his "special qualities"
.
Just today I had a text from my "different, original" son, telling me he had achieved 100% in his final exam in the medical field he's been studying. What's more he's been struggling with the most dreadful health problems which meant that one night recently, he discharged himself from Addenbrookes so he could take an exam the next day. Which he also passed.
So thank you to all you teachers who see the individual child. Really, a big, big thanks.
