Watching my toddler grandsons, I observe them learning. They can both concentrate when they are not interrupted (by parent or brother). The nearly two year old at a “Messy Play” event once a month, is given pens to colour in, but does no more than the obligatory draw of the pen that he sees the grown up wants. No one has yet shown him how to hold the pen and I think he’d ignore them if they did. But he is fascinated by the way pen lids come off and go on. He can happily spend half an hour pulling and pushing lids, gesticulating to be given another pen in order to try that lid too. He has also spent half an hour on a paste stick, poking pens into it, pushing the paste up and down.
Susan Isaacs believed in nursery education. Issacs emphasised the value of play in nursery school, with bricks, sand, clay, art and craft, which is what Messy Play afternoons are about.   They also provide opportunities to play with other children, or at least to observe them, observe how they play, observe how the adults interact too.
Sometimes, as a tutor of adults, I’ve had the chance to observe my university students actively learning. Once, I knew a student was close to working something out, whilst her neighbour who already understood was dying to explain it to her, but waited when I gesticulated. And the student got it! That is what is so satisfying about being a tutor – seeing students achieve understanding through their own efforts.
I can’t see that achievement with online tutorials.
