I don't think the UK education system is ready for more IT. All I've seen at my son's school is a lot of time wasted in badly thought out initiatives that are soon forgotten. It's usually nothing but fur coat and no knickers. Teachers doing the same stuff, but using a computer instead of traditional methods. So, they'll still create a home made scrappy worksheet and email it out instead of printing it - but still the kids have to print or copy it to write the answers - doh! Likewise, online textbooks are often just pdfs of the paper one with no hyperlinks, no automatic marking included etc. Just one wasted opportunity after another. Then so many teachers just don't use the facilities they should, such as show my homework.
They should be using new teaching methods more suited to the IT available. My son has just done an open university module, all on his iphone - he could read a chapter whilst waiting for us shopping in the town centre - then before he could move on, he had to complete end-of-chapter texts, some multiple choice, some wanting specific single word or short sentence answers - all marked automatically so there was a running record showing his scores, which questions had to be repeated etc - all excellent for monitoring etc. No "human" intervention required by teachers etc. I thought at the time it would be ideal for schools as it leads, controls and monitors through each subject all automatically. In schools, that would give teachers a massive amount of extra time to help the strugglers if they don't have to do so much "hands on" work with everyone and let the more capable students study virtually independently.
