I'd suggest getting hold of the Education Otherwise http://www.alicebachini.com/ newsletter, or contacting similar local home education groups, to see what kind of stuff they might be interested in.

The two obvious difficulties are 1) home educating families often sacrifice an income in order to home ed, and therefore don't have a lot of cash to spend, and 2) a large proportion of home educators value self-directed learning over traditional teaching by experts: they are actually rejecting the teacher/ pupil paradigm as the only/ best method of learning.

My view is that most teachers are paid precisely because they have to deal with the public school mess- they are crowd-controllers, babysitters and moral disciplinarians, and that's what society puts a premium on. Actual learning is not only severely limited by the constraints of the classroom, but sheerly pleasurable to share with a child when they are able to do it under more humane conditions. Imparting knowledge to children who are interested and in the mood to learn is extremely easy and enjoyable- and that's what motivates school teachers to put up with the crap. But I doubt it will be considered a specialist skill worth paying for so much as a human privilege, if in the future home educating becomes the norm, particularly as knowledge of all kinds becomes more and more freely available from forums such as the internet.

My father is a retired teacher who earns some income by giving private tuition. He's put in touch with his students through some tuition agencies which can be found in the Yellow Pages, and some of them have websites. I don't think most of the agencies insist on formal teaching qualifications, but they will demand evidence that you're competent to teach your subjects.

Most of my father's students are sitting Standard Grade and Higher Geography, who are getting additional help outside school, but some of them are home schoolers. A couple of them, I believe, were the children of creationists who didn't want them to be indoctrinated by conventional schooling. My father was given a list of things he couldn't teach them, which I suppose must have put him in a minor quandry since it meant he couldn't say anything about the Ice Age.

Writing course material on computer-related topics for homeschoolers might really succeed. I don't know what age-range he'd be willing to write for, but my 10-year-old is dying to learn about computers, but I'm somewhat computer-illiterate (internet and Word documents are about as far as my talents go), and the more I try to understand, the more confused I get. If he could design a course or two that is written like some of the science and other programs-towards the student, with enough teacher (parent) support, and maybe a website that offers some extra support, if needed, I think he would do well. I don't know how feasible it would be to start such a project, what kind of work would be required, startup costs, etc., but I do know there are quite a few homeschoolers that would be interested in such a program. Tutoring and community classes might also go over quite well.

Alice hits the nail on the head (as usual) with regard to the teacher/pupil relationship however, there could be some leeway in offering services to individual home ed. groups as a kind of "Resident Expert".

What you will have to consider though is that unlike being a teacher in school, these kids will listen to you when you are interesting or they are interested but will wander off to do something else if the fancy takes them. I know for a fact that 'teachers' find this really frustrating as they normally have a plan and tend to think that they, and their opinions are far more important than those of the children. So if you have ideas of pontificating to a captive audience stick to school because free spirited and intelligent home ed. kids will find you out!

I don't think the majority of home educators are dogmatic about excluding paid specialists. We pay a piano teacher so I can't see any reason why we wouldn't pay a computer teacher when the kids are old enough. I imagine the same is true of other home-schoolers, although obviously the rates they could pay will often be relatively low (reflecting generally low incomes in home educating families). It all depends whether the subject is one which would benefit from outside involvement.
