In the first series of That’ll Teach ‘Em, Twenty Twenty set out to answer the debate once and for all, with a major reality/living history series. Thirty academic kids were sent back in time to a reconstructed 1950's boarding school. Strict teachers, tough lessons, lots of physical exercise and a diet of no-nonsense, healthy food were all par for the course, and at the end of four gruelling and rewarding weeks our kids sat genuine 1950's exams. The results were astonishing. And the series was a major hit for the UK’s Channel 4. The second series asked if we are failing the less academic kids of today. Instead of GCSEs in Media Studies or Citizenship, our school offered the no-nonsense practical lessons of a 1960s secondary modern. Rural Science, Bricklaying and Cookery were all on the timetable as once again, thirty kids went back in time to try it out. Once more, the results were a national talking point as we showed there’s still a case for vocational training. A third series of That’ll Teach Em is currently showing on Channel 4 in the UK. With boys falling further and further behind girls in today's exam tables and displaying chronic disinterest in the Sciences, the third run of this historical reality series sees single sex classes introduced, and thrills, spills and explosions in the science lab. With a practical, 1950's education imposed, competition runs high. But will the boys close the gap, or will the girls stretch their lead?
