When I went to school 100 years ago in the US there was a "Business" track that taught typing, basic accounting, shorthand, etc. There was also a "science" track for math, physics, etc. People could pick and choose among the courses so, for example, many college bound students took typing because they knew they would have to write papers in college that would have to be typed.
In my mind it seems clear that USING computers, MS Word, Excel, etc belong in a vocational or "Business" track. Programming belongs in a separate area such as a computer club or perhaps in basic math to teach students how to program a rpi to graph equations - a useful and relatively simple programming task to get started.
I am retired but I plan to teach a linux and then a python class in the local high school. The class would be after school as part of a computer "club". I will need the cooperation of the school but I think they will be happy to have me Students will have to buy their own rpi which they should be able to do for under $200 or much less if they have a TV or monitor they can use. I feel any UK or US student who is really interested would be able to scrape up the money for a rpi. Asking the student to put "skin into the game" sorts out the ones that are really interested from those who are just trying to kill time, find a new boy friend or girl friend, get out of the house, etc. etc.
Changing the curriculum is hard and, while I think the Foundation should pursue it, I don't think it is the place to start. Starting a computer club, either with the schools blessing or not, is easy and will attract those students who would most profit from a rpi. Just my two cents or pence as the case may be.
