History would be taught for half an hour a day half of the months when Science wasn't taught. For two lessons a week, we'd read books getting an overview of our topic. For another lessons, we'd look at primary source documents. In the other lessons, the kids would respond to the reading in various ways...
Geography would be in the non history/science months. The kids would learn that England is not part of Asia and that Melbourne is not a state. I know there is more to Geography than this, but basically I wouldn't care if was all just maps, maps, maps. There are basic things that everyone needs to know.
Music would be taught for half an hour each day following a (seriously accelerated) Kodaly model. From year 3 students would be expected to be learning an instrument privately. There would be orchestra and concert band and choir of course.
PE would be taught for half an hour a day with two lessons a week run by a specialist. Two of the non specialist days would be pure cardio training. Get out there and swim/run/skip. If you aren't puffing, you're not working hard enough!
Maths would be taught for an hour each day by someone who understands it and likes teaching it. (I understand it, but hate teaching it to kids who don't. get. it.)
English would be taught for an hour and a half each day. 15-20 minutes of that time each day should be spent listening to a story. 20 minutes should be spent on spelling. Two days a week should be spent on skills training - comprehension, grammar etc (Texts that are used for comprehension tasks should be carefully graded so that kids are working at a good level for them. They should also be worth reading.) three days a week should be spent in more creative, interesting, analytical... joyful pursuits. Poetry must not be taught by people who have no interest in poetry. Kids who are struggling to read and write should be assessed by educational psychologists, speechies and OTs to work out exactly what is going wrong and plans put in place to help them progress and remain engaged with learning despite their difficulties.
Visual art would be taught by a specialist for 2 hours a week.
Dance and drama would happen within English and PE and also have intensive bursts with specialists a couple of times a year.
There would be only 20 kids in each class.
Homework would be minimal. Home readers would be worth reading. Technology would work.
