Only female in A level class

I’d explore the impact on her other classes - she can then make an informed choice. I’m a teacher and 6th form tutor and have dealt with variations of this issue.

Being a girl mathematician, I've been in similar situations on many occasions, and honestly, it's not an issue, although tbf I normally could out maths the boys which may have helped.
I found they treated me with wariness initially, moving to respect when they found I was better than them, but fairly quickly they forgot that and treated me the same as the others.
They did love it when I (rightly) corrected the teacher though.

I was the only girl in my geography class, I didn't find it a problem but I'm not shy and and I had a massive crush on one of the boys and got to sit next to him. I suspect your dd is a lot more studious and sensible than me though if she's doing physics. From a teacher point of view I can totally see how this might be hard for her. I think whatever she choses has to he her decision at this stage though.

For what it's worth, 25 years ago when I worked in a sixth form college and did timetabling, we checked for imbalances like this and did all we could to avoid them. So not that impressed by the college here, though it's possible another girl was originally timetabled in that class and dropped out of the subject or the college. (I'd be on the side of moving, if it were my DD.)

My dd was the only female in her A level physics class at her grammar school .
Originally there were thirty students in her class and after two weeks thirteen dropped out ( four of the thirteen were girls) .
This left dd and sixteen boys . Dd wasn’t happy about it at first but she liked physics ( at the time ) and didn’t want to change subjects .
She eventually got used to it and was fine

I’d recommend getting used to it if she likes the subject. I was the only girl in my higher and csys classes thirty years ago then one of five out of 50 in my degree cohort. It’s not great I wish it wasn’t the case it’s better now but it is still a very male field.

But there are lots of girls young physics. Just not in her class

The OP will know best how her DD would handle this scenario, but she did mention lack of confidence. I expect there will be other occasions where she can work on her resilience without compromising a crucial stage of her education.

Statistically "tend(ing) to receive less attention" does not equate to "letting the boy dominate" though, does it ?

Having said all that…

Back on those days IT was a new and shiney subject, and all the numerate kids were were begining to pick it over Physics, so my Physics cohorts were all pretty small, and i never felt overlooked.

I was in that position many years ago. What was upsetting was seeing your friends bonding, making friends and having fun in their lessons, whereas I sat at the end of a science bench on my own for two hours at a time. The boys in my physics class were not yet friendly with girls.

I remember the first day of my physics course at university. About 40 male students had arrived for the first lecture when a lone female arrived - there was a spontaneous cheer... and sadly, she turned around, walked out and was never seen again... and I think that was such a shame. I've had a wonderful time working with many smart women in various physics related fields over the years and I have always valued that sometimes we don't think or talk about things in the same way... it's perfectly possible she could be a real asset if she can get past this initial realisation that she might often be the only woman or one of few women working on a particular project or in a particular team or environment.

We know that boys in general dominate in the classroom.

This recent study for example:

"Girls tend to receive less attention when paired with boys, even when they are the lower achieving student in the group. Lower-achieving female students in mixed-gender pairs receive significantly less attention than their higher-achieving male peers, while lower-achieving male students receive significantly and substantially more attention than their higher-achieving female peers."

I was the only girl in my A level Physics class.
Then I was the only girl in the Physics part of my degree (joint honours physics and geology).
After that I was the only girl on my MSc course.
I’ve since been only one of a handful of girls in my office more than once, and the only girl on a construction site several times.

It’s a non-issue. I have plenty of femal friends elsewhere.

What ???

Why would you think that?

Why do you think she would 'give it a go' if there happened to be another girl in the class, but 'let the boy dominate' when paired with a boy

What an odd way to think.

It's maybe useful to get used to being outnumbered in the relatively safe environment of school. And I agree that being one of two or three girls is not necessarily better. I taught a maths class with two girls, one of whom was a poor attender, and the other preferred it when she wasn't there!

If it's bothering her, it may be worth a quiet word with the teacher. They may be able to ease things - and I'm thinking particularly for practical work which might be done in pairs - if they allocate the pairs then it avoids all the boys pairing up and leaving her out.
(DD was the only girl for chemistry, but there were only four of them, so it was never a problem for pair work.)

It's going to be disconcerting if she wasn't expecting it, but it's often a reality in a physic class in a mixed school.

Talk to her and ascertain the underlying reasons for her unease. If it is concern that they will be inappropriate, raise it with the teacher to ensure off colour comments are instantly smacked down.

If it is concern that she will not make friends, ask her to give it time - and to think about how she could engineer the issue, based on the personalities around her (and her own).

If she's happy in her other classes, and there's no identifiable impetus to change things, I'd leave it as is and she'll get used to it.

I’m sorry to say that many parents have absolutely no idea how complex timetabling is and certainly do expect the timetable to be built around their child! I’m pleased to encounter a parent who is cognisant of the reality

I’m sorry but what is the issue ? This is a situation she may find herself in throughout her working career how will she manage that ? It’s a total no issue and that’s how you need to deal with it , it’s about learning some resilience and understanding that sometimes in life you don’t always get exactly what makes you happy / comfortable. I was the only female in my chemistry class 40 years ago and throughout my career worked in a male dominated industry so was often the only female in a team / part of the management. It will teach some really valuable life skills about how to be respected and heard in a male environment.

There's a lot of survivorship bias on this thread. Sure, many of us experienced the same thing and were fine - because we were top of the class, or resilient, or were lucky to have brilliant teachers/mentors, or actually thrived in an environment where we were a bit different.

But many of the female undergraduate physicists I teach are still telling me even now that they are sidelined by their male peers doing experiments, or subject to inappropriate comments on academic group chats, or were told by their A-level teachers that "girls don't do well in physics" (multiple, in recent years - I'm not making that up).

Why should it be up to them to learn to tough it out? Why should they have to swim against the current right from the beginning, at 16? Yes, physics is a male-dominated subject but the point is it shouldn't be! And it won't change if we don't make room from the beginning for girls who are not top of the class, or not particularly resilient, or don't find their confidence until they are a little older.

I promise this scenario is being repeated in classrooms across the country. It's significant that all-girls schools are much more likely to send girls on to study physics post-16 (to quote the IoP).

So I really hope that OP's DD is supported to make a decision that works for her, that her teachers are aware of gender bias and proactively work to create an inclusive classroom, and that her school is keeping close records on their statistics and making action plans accordingly. Because these are things we can actually do to make change long term, rather than putting the onus on individual students to sort themselves out or muddle on through.

I did Higher Geography in Scotland in the late 80s and was the only girl out of a class of 20. No issues.

I think you have to validate her feelings, try to find out more what they are about, and help her go through the options. It entirely depends on the boys and teacher in question. If she has had attention drawn to the fact of her femaleness already perhaps it’s not a great environment. I wouldn’t make light of it - being in an all male environment can be intimidating as I am sure nearly every woman on the planet can attest to.

@ThanksItHasPockets We all know that timetabling is complex and nobody would expect the entire timetable to be designed around the needs of one student. The school can't magic up more female physicists. However, it appears there is an alternative timetable that could have been allocated to this girl and now been offered. Presumably this is because she is doing a combination of subjects that is available is several timetable slots. If us this is the case then it could have been offered in the first place and not put this student in an uncomfortable position.

It is useful to discuss lessons with the other students in a class outside of lessons. If this is made harder by the gender balance then it may be worth swapping. Or maybe start a girls in STEM society.

It is such a shame, though - in my Midlands all-girls’ school in the 1980s, half the year group did Physics A level (the other half did History: only 3 girls did neither, as I found out when I had to timetable something). We were taught by female teachers, all but 1 with PhDs in the subject.

The fact that in the last 40 years, the gender imbalance has remained and is still so acute is really sad.
