“My school has just announced that from September, it will be co-teaching French, German, Music, Textiles and Theatre Studies A level in mixed year 12 and 13 classes, due to a lack of funds.”
“Must be chaotic, though and really hard in languages, I'd have thought.”
Actually it works really well in languages. The syllabus is over two years and it can easily be overlapped so that the current year 12s are learning the same as the year 13s, then next year’s year 13s will be learning the same as next year’s year 12s.
My school did mixed lower and upper 6th for A level French and for A level Home Economics, and it worked really well. The subjects aren’t like maths and sciences where you need “building” blocks before going on to the next stage. The work doesn’t get harder. It is just more work.
I think it would work well with history and geography as well.
