Een deel van deze les bestaat uit luisteren met vragen en een deel zelf verwerken. 
Why this subject?
  • There is plenty of technology in all the tasks of life that you have to deal with. That is in fact your duty. 
  • This often changes so you have to keep understanding.
  • There is work to be done because government research states that most young people find technology difficult. Being handy with your phone is not necessarily the same as being handy with everything else.
  • This subject lays the foundations for later.
