I do have some experience of Steiner Education (though my kids are state educated). The principles of Rudolf Steiner's philosophy are adhered to by teaching children in 7 year cycles, this is why they have the same teacher throughout lower school (years 1-8) who forms a very close bond over this period.
TV is not encouraged (frowned upon really) and the children are not introduced to computers until year 9 (14 years old) when they have different specialist subject teachers. Music is taught and practiced daily (recorder) and the children knit (hands on crafts are part of the curriculum, woodcarving, pottery etc). There is a lot of outdoor work, animal husbandry, repairing fencing and grounds maintenance as well as gardening and farming with the emphasis on biodynamics (Google the method, it's partly crop rotation, partly magical thinking).
They follow concentrated one subject lessons for half a term and have a structure of 1 day listening (teacher talks), next day discussion in class, then next day record information (the kid's workbooks are like works of art, their musings are always accompanied by illustration alongside their essays). Sleep is considered vital to this process (especially between listening and discussion days).
The school day starts with Eurythmy (again Google it) which is a vital element to how the children learn to read. In a nutshell it's a combination of meditation, dance/movement and yoga-ish martial art performed in a group. A 'B' sound has a specific shape and movement for example. It's used to focus and bond the children before they begin the days learning.
There is however, an antivax climate and Rudolf Steiner believed in reincarnation (this is where the controversial race issue comes in, it's the idea that as we move through life and become more enlightened our skin colour reflects the change by changing from dark to light, I should add that this thinking is rejected today, but that's the origin). I think of the Steiner ethos as a merging of Christianity (angels seem to be a theme), Buddhism and Paganism, but this is my own perspective formed from observation of other people's children who have been Steiner educated.
I don't think it's for everyone, it can be restrictive. They claim to have no uniform but essentially we're talking about hand-knitted wool jumpers etc (no logos or labels allowed) which is its own form of identity in itself (crunchy?). The kids and teachers also wear indoor soft slippers. I think there is a connection too to those who believe in "Indigo Children" (another Google, sorry).
