you need to have a word with yourself if you think just because a person went to school they will be fine to home educate
@MsEllany, I think you are imagining that home education looks like school. Few home educating parents use the school-at-home model, and therefore we don't need the same skills as teachers. For example, we don't need to be able to engage dozens of pupils all at once in a busy classroom, deal with disruptive children, or understand the individual learning needs of a child we barely know. Our job is much easier than that.
I see myself as a facilitator, not a teacher. I help my children find the resources they need in order to learn. For example, my eldest was most interested in subjects about which I knew nothing: music, art, and sports coaching. I helped by looking for for online resources, books, knowledgeable people, courses, choirs, music ensembles, tutors, and sports sessions.
However, my teen was also able to identify many resources without my help, especially as they got more advanced and better at networking. I had very little to do with it in the last three years before they went to university. In fact, there was only one subject they studied which was very familiar to me, namely maths. I have a degree in maths, so I always assumed I'd be delivering lessons in maths for GCSE. I was wrong. It turned out that my kid found many other resources to prepare for maths GCSE, and I only gave a small bit of input very occasionally. My help wasn't instrumental. Often, "lessons" from a parent are neither needed nor wanted!
Those of us who went through the school system tend to assume that the way we were educated is the only way or the best way. It isn't so. Sixteen years into home education, I am still unlearning all that I thought I knew about education.
