OP - In my opinion I dont think extending school hours would aid learning especially in a primary school environment. Having a wife as a primary school teacher i can say that the level of practical work depends on the school and there approach to teaching the curriculum. Having been in her school to help set up her class in the summer i can say they do plenty at her school with photos, art etc on the walls and going on trips to try new experiences and learn about other cultures.
I would like to see homework removed from a teachers point of view as marking 35 kids books maths english science and any other topic covered that day may stop her marking until half 8 / 9pm each night and then planning all of it on the weekend for the following week. However i think it should play a role in a child's school time as it lends to independent learning. Parents should be involved in helping educate their child it shouldn't just be a drop off and put all the pressure on the school to provide you with a A* (Was letters when i was at school think their numbers now?) child when you pick them up at the end of the day. Methods might have changed but is it really that different. I might do say multiplication different to how they are taught now but it wouldn't take me that long to get my head round it.
Funding would need to significantly increase. They have cut teaching assistants right back recently and her school have had to let a couple go as they simply cant afford to employ them. I dont think there would be a big struggle to find teachers though should you employ 2 over a school day at their current salary level. My wifes first school had over 100 applications for 3 positions available.
By extending the day yes more breaks would be needed as suggested but i would question how much extra teaching will be accomplished. The cost may be cut to the parent for after school club but where would the extra money be sought for the extra meal / food for the extended day?
I agree with supporting teachers more. Its the admin and size of the curriculum that need addressing with goalposts constantly moving and testing bigger than ever. (Not aimed at yourself) But dealing with parents is also a tricky area with teachers afraid to say anything with fear of a complaint.
With regard to secondary schools i think this is where is much more room for restructure of days lessons etc and where slightly more investment is required. You can leave primary school having done well in SATS and then perform drastically different in the exams that count at secondary school. Im not knocking primary schools as they provide the foundation but having had friends of different levels of intelligence , results can be the same across those levels come the end of your A levels.
Then again i dont work in education or like children ha
I would be interested to see the results of some schools that could try this setup for say a term before I could be convinced it would be a major benefit that should be implemented across the board.
