>I was a trouble maker at school.

Everyone has different motivators and different idea's of success. Some of those ideas can lead to being classed a criminal, but the state wont accept its own part it plays in people's failures. Until the state recognises this, you will continue to have failure's in people who shouldn't really be failing. Family can also contribute to a persons failure, you cant help it they have different idea's to your own but a lot of parents view their kids as possessions and they don't always accept a kid can form strong beliefs and desires from a young age even though we hear of people who have managed to pursue childhood dreams.

>Sometimes disruptive kids need to be told they are capable
I'd agree with that, but having a suitable person to recognise this and guide them is hard, some benefit from a hands off approach others benefit from a hands on coaching position. Out of all the secondary school teachers only 1 would defend me in the staff room, I really pushed the boundaries and challenged people even teachers, but anyone will know cognitive dissonance can create powerful anger in one or more people.
I don't think the UK is geared up to educating and exploiting the talent of each individual to their max yet but I hold out hope.
>I think a lot of disruptive boys can really benefit from a strong masculine teacher
Certainly at primary school I gave female teachers a hard time especially if they didn't "flirt" with me and yes kids can have feelings at that age largely controlled by oxytocin imo, but I think it was a respect to the hidden but generally controlled anger you would sometimes from older male teachers, it was a shocking sight in some ways because older people are generally more laid back so to see them lose their temper was more of a shock than a younger adult who lost their temper more frequently.
I also respected the older teachers more than the young teachers, whilst at primary school (6-7age), I am supposed to have caused a young female teacher to have had a nervous breakdown which perhaps backs this idea up, but I came from a very strict background where extreme corporal punishment was also the norm. Even at primary school I was very competitive, often completing work in the classroom first then disrupting the rest of the class as I hated having to sit in silence. When the teachers started setting me extra work to keep me occupied, that lasted for a few days as there was no extra benefit, but it proves some primary school kids can be highly motivated and quite likely the most disruptive. I wrote my first program on a ZX Spectrum one summer around 7-8yrs when it first came out because student neighbour had one and was studying computer science at Uni. He taught me to write basic programs. I didn't know what I was doing was considered hard or difficult because I hadn't been socially conditioned into thinking it was hard, here was something novel and fun which fitted in with the scifi like Dr Who/Star Wars I liked to watch. That I think is an important point, kids learn when its fun, if you have everyone including the teacher saying we are going to learn some hard maths, physics or sciences, the teacher, parents and older peers have subconsciously created a barrier to learning in the classroom. Its why we need to be careful what we say around kids because they are sponges for knowledge and we should be exploiting that better, but I think AI will be taking over soon, which is my primary interest. Cambridge is nice, could have gone, but education held me back imo so I pursued my own non educational path. Do I need those pieces of papers, no, I work for myself because no one has yet to build a general AI and so no one can teach people how to build one. Having a belief in yourself is also important which can be hard some days when things don't go right and then it can be easy to blame others for our own failures which I see a lot of in this thread. Noone will do it for us, we need to do it ourselves, but getting the right environment to make that happen can be hard and we don't always recognise what is a bad environment for us, in fact that can sometimes take years to spot so having periodic times of reflection can be a good thing when looking for ways to do things better and trying to be the best in the world!
