Magdelene,
1992, in teaching terms, is such a long time ago as not to be relevant to what is happening in schools today.
As with all things in school, there are 'fashions' in these things. As a school child in the 1970s, I hit 'child centred learning' and 'topics' in full force. The National Curriculum arose in reaction to that, and the current creative curriculum approach has responded to the worst excesses of the 'compartmentalised' learning that created. The 'lunatic fringes' of each approach are not goiod - the truth is, as in all these things, somewhat more nuanced.
I feel that cross-curricular learning is the BEST way to introduce knowledge that cannot be enountered elsewhere. If I had taught Hinduism in isolation, to my very rural, very white class, it would just have been dismissed as 'alien'. However, it was linked to a whole topic (which took a whole term, so covered all aspects in depth) on India, and in that context it was relevant to the kids and they absorbed it like sponges. I think of it as being like Velcro - the more 'hooks' you create for a child to link new knowledge onto old, the more likely is the child is to genuinely learn and absorb that knowledge. So the children already knoew about India, about its geography, its people, typical lives of the rich and poor - then we worked on Indian Myths in Literacy in tandem with learning about Hinduism in RE. Even now, 2 terms on, their recall is fantastic, and at the time the depth of understanding, the type of questions they asked, the appreciation of an unknown culture was far in advance of what I would have expected from 7 year olds.
I really do question the source of your information when you state that learning in state schools is all about skills. This week in science I will teach my class about magnets - and yes, they will experience magnetic force and learn the skills of carrying out a fair test experiment, but they will also learn about magnets. In RE, they will learn about the Bible and its use in Christian worship - and use the skills of textual analysis to study how Psalms become hymns. In Maths, they will analyse data using different types of graphs to answer questions they have come up with - yes, a skill, but one which needs knowledge to underpin it. And in Literacy they will learn about how an adventure story is structured and begin their own extended writing. I could go on - but is this really 'content free and all about skills'?
On the other hand, I use the SKILLS I learned through my education many times every day. I use the specific knowledge very rarely, and would do so even more rarely if I wasn't a teacher. When did you last use a particular piece of knowledge you learned at school in your daily work? Or do you instead use the skills - of research, of adding money, of structuring a text, of comprehending the meaning of a text, of deciphering something in an unknown langiage, of making a fair test or comparison, of weighing evidence?
