@JulieNS: Hope SDeuchars comes along and sees this thread. I'd have loved for our kids to have been involved with the South Wilts group's adventures!
OK, I'm here, but not for long - today is Robotics day! Julie is referring to the North Wilts FLL Robotics team (which has a website). It has been running (from my house!) for 6 years and we've had upwards of 25 kids aged 9-16 involved (up to 10 at a time apart from Y1, when we also had two foreign exchange children). We take part in a competition to build and program LEGO robots and we usually win something at the UK final. We have taken part in competitions in NL, and Japan and should have gone to Turkey this year (but the ash cloud intervened).
BTW, if anyone is near Bristol (UWE Exhibition and Conference Centre, Filton) we are in the regional tournament on Thurs 25 November and we can have as many supporters as we like this year. Contact me on [email protected].
To return to the OP, we've been involved in groups since about 1995. I joined EO then and went along to the local group in SW London. We didn't get on with everyone, but I generally found that there were a few people I could relate to and that there was some point of contact and discussion with everyone.
When your children are older, you can plug in to other ("normal" after-school) activities (sports, music, youth orgs, etc.).
Life is freer as an EHEer. If you come out of a group meeting, you can often then go off with another family or arrange to meet up another day because both the parents and children know each other. At the school gate, the parents aren't really going to know much about each other.
When we moved to Swindon, I used the internet and EO contact list to find out about groups here and we joined in pottery, swimming and other activities. I have no experience of groups that meet for structured school work. Our groups have either been special interest or simply social. My DD did find it difficult the last 18 months or so as there were very few other EHE people around in her age group, but I suspect that would have happened if she had been at school (our local comp gets 27% with five A*-C GCSEs). Although robotics helped as she had access to a load of adult women (mostly) once a week. She also was confident about joining adult community groups (e.g. church homegroup, a toddler group and an evening class in ballroom dancing).
EHE young people take others seriously and expect to be taken seriously. Teachers and others often say "they cannot relate to their peers in secondary". IME, this is because they do not expect to behave like "typical teens" - they are in charge of their own destiny and learning, so they do not need to rebel and muck around. My DD was always odd, so it not necessarily a good guide. However, my DS is neurotypical and has not been hanging around the adults so much (more choice of teen boys to hang around with). He is growing into a young man who relates well to adults - respectful without being deferential. He gives his opinion in the way you'd expect another adult to do. People used to schooled teens often find that difficult (in fact, my DD did a term in school at Y5 - her choice - and the teachers could not cope with the idea that she was not being rude but assertive...).
I'm also aware that the relationship with the others in the robotics team has changed - we are very much a team now, rather than adults in charge pushing them on.
Rubimou, if you'd like a phone conversation, I'm up for that - I could wax lyrical all day!
