    We can use games to make a new toxic mess if we use them merely as a shiny new delivery device for old, bad ideas about teachers, testing and learning. Just like books, games are a technology that can be used for good or ill. Textbooks are the least good educational tool ever made (VanLehn et al. 2007) because they seek to be a one-size-fits-all, standardized, single system, stand-alone delivery platform for facts fit mostly for testing. Games should, together with other tools and with good teaching, deliver customized and collaborative problem solving for a complex, high-risk and fast-changing global world.

  • For now, anyone thinking about how much time using screens and social media is "OK" will ultimately have to make a personal judgement.
  • Rather than stating that social media was harmful, it suggested a more complex effect.
  • increasing the time spent using technology was linked to improved wellbeing
  • ...6 more annotations...
  • the positive effect of regularly eating breakfast, or getting a proper night's sleep, was three times stronger.
  • the effects were small, with the positive effects of exercise being more significant.
  • A broader look at evidence provided by some other high quality studies again suggests the story is not clear-cut.
  • Playing electronic games, however, was not seen as leading to a greater risk of hyperactivity, or friendship or emotional problems
  • So how much time should we, or our children, spend looking at screens? It is difficult to be precise as different people spend time online in such different ways.
