Agree, @Ubertomusic ; the situations with university and work aren’t relevant to the kind of in-class “mentoring” posters were talking about earlier on this thread. The examples of prefects, or “sciences mentor” in the upper years of secondary school (which are more like leadership, pastoral or subject ambassadors) aren’t the same kind of thing either.
My DD, for example, is gifted at maths, but at primary school would finish her work and ask for greater depth and extension work, but instead would regularly be asked to explain the concepts to children who were struggling, or to help other children with their own work instead of being given extra work (most especially in the run-up to SATs). This is the kind of peer teaching/mentoring that we’re talking about. There are two issues here: one that even if this is occasionally a useful task for both children, for it to be regularly a substitute for developing a child’s own work and knowledge should not be acceptable. Yet this is often practice in mixed ability (or even setted) classes in state schools, especially where a teacher either can’t or doesn’t want to provide extra or extension work for one or more outliers working beyond the average.
The second issue is that, during the time DD was at primary school, the guidelines in the primary national curriculum changed from requiring schools to give greater depth students extension work beyond that particular KS curriculum topic, to requiring them only to give extension within the relevant KS topic. This meant that once DD had been given a greater depth worksheet and had finished it, she was often then put to work explaining the topic to other pupils because the teacher simply hadn’t prepared anything more for her to do, but was also not required to give her work beyond the curriculum. So DD ended up massively frustrated and bored, and also pretty pissed off at being used as free teaching labour for the class (because even in primary kids realise perfectly well what’s going on).
None of this is actually developing a bright child, but, as a pp said, just using them as “fertiliser” for everyone else. But that is the key issue, isn’t it? Keeping the bright kids in one comprehensive system might do a bit of fertilising, but those individual kids suffer with frustration and boredom as a result. If you are looking at the system overall, you might think that’s a reasonable sacrifice. However, if you’re one of those kids, or the parent of one of those kids, you aren’t going to be that happy at being sacrificed just so everyone else does better.
Similarly, research on secondary school achievement often shows that boys do better in mixed schooling and girls in single sex. That means that if you have boys, you’re keen for the girls to be sacrificed so your boys can do well. If you’re a girl or the parent of a girl…maybe not so much. Who gets to win? Well, the fact that since the early 2000s almost all state schools have gone mixed, even if they weren’t mixed before then, suggests that someone is winning (and it might not be the girls).
In our case, we accepted the situation for DD at primary, but we weren’t happy with seeing her go through all her secondary career having the same experience over and over again. And our catchment school made it clear that they had a limited amount they could do for her.
So do you think, @CurlewKate, that DD should be frustrated and miserable in a setting that doesn’t suit her, just because that’s what suits others? I spent seven miserably unhappy years in a similar situation before I was able to escape to university, and I don’t want that for DD (who already tests out as brighter than I was, though these things are not exactly a hard and fast science).
