@jennymanara we home educated our two boys for several years. We were never 'inspected' and they played Minecraft a LOT. For years actually and it seemed non stop at times. And that's all you would have seen them do or talk about if you knew us/came round to our house.
We didn't follow the national curriculum, in fact we didn't formally teach them anything. However Minecraft does have many educational benefits.
But what you won't have seen is that we talked with them/to them a LOT as well. Discussed anything and everything. We went on lots of days out. Where they showed an interest in anything, we went to find out more about it. We all learned something along the way.
My eldest taught himself how to strip down a computer and build one from scratch, getting himself a part time job at the age of 13, repairing computers for paying customers.
They both returned to mainstream education at the age of 14, because they wanted to. They settled in really well, mainly because it was a small school with amazing teachers.
Whilst many of his peers failed their GCSE English language and Maths, my eldest son passed with flying colours. In fact he got the highest scoring mark in literature. He's just taken 4 A levels.
My youngest has just taken his GCSEs and has 3 offers from 3 colleges in his chosen subject.
Unless you're actually living with a home ed family for some considerable time, day in day out, you have no idea what they are actually learning along the way. It's just that schools are very good at telling you what they are putting in front of the children, but that doesn't mean they are actually learning and retaining any valuable information. Both my kids are independent thinkers and doers, which is exactly what we wanted for them.
