It really doesn't need the Tech Industry to help with this
The following steps are simplified but the nuts and bolts of this plan are not rocket science and there are plenty of other countries who can offer all the advice that is needed.
1) Scrap all league tables. For every type of school at every age group.
2) Scrap all centralised exams except for the GCSE and A-Levels.
3) Give all teachers a pay rise immediately at five times the current rate of inflation.
4) Let teachers teach. They decide how they are going to teach a certain topic, what skills they will assess during the teaching of that topic and they decide how and what the assessment should be upon the completion of that topic.
5) Scrap infants school. Mandatory schooling should only start in the August of the year the child turns seven.
6) Scrap the stupid "school year" for deciding what children are in what class. All the children who turn seven at any point in 2018 should be starting school next week. In the first year of school.
7) Allow an entirely optional, completely free, one year of "pre school" starting in the August of the year that the child turns 6. This should focus on introducing children to the environment of school and peer awareness rather than getting a jump start on subject material.
8) An example of a school year: August 13th 2018 to October 12th 2018. October 22nd 2018 to December 21st 2018. January 7th 2019 to March 8th 2019. March 18th 2018 to May 31st 2019. Good Friday is a day off and the only time off for Easter. One "national holiday" day to also be taken off. Yes that means the summer holidays run from June 1st 2019 to August 12th 2019 next year!
9) School day starts at 08:50 and ends, at the latest, at 15:00.
On a purely personal level I would also scrap school uniforms but I don't think the UK is quite ready for that yet.
