Ideas, experiments and observations as they occur [and I have time] relating to teaching and learning in a secondary school - special focus on ICT.

The Ellsberg Paradox, school and trust

Leigh posted "Fear paralysis, Ellsburg paradox and what’s in a name" and referred back to a previous post "What’s in a name? Why some succeed and others fail". Basically the Ellsberg Paradox means that we will tend to choose in favour of things that we know about, hence Leigh's words 'Fear paralysis". He believes that this is a factor that inhibits people choosing FOSS. I agree. People tend to favour the things that they know about and have learnt with which is why it is important that schools provide the chance for students to experience FOSS as well as the proprietary products in school. I think that we should be learning with the free stuff first so that the risk is in taking up the stuff that costs a lot.

As I watched the short video that Leigh pointed to about the Ellsberg Paradox it triggered some thinking about one of the fundamental things we are trying to teach in school. We have this innate mechanism which inhibits our ability to go into the unknown and yet education is really all about taking people into the unknown. Taking a risk, moving into the unknown, conducting experiments and the like. This to me points to the importance of teachers being trust worthy.

In my post "Play with Stuff" I talked about challenging kids and the whole post was about taking risks. I think that having seen the video, the Ellsberg Paradox is the mechanism that we are wanting to play with and learn to control so that we can get to a point where we are more likely to venture into new ground.

As my grandfather often said, "Nothing ventured, nothing gained".

Playing with stuff

Two related posts

This conversation is very much about developing creativity or hacker thinking

Things I like to do:

Have students take apart old computers. I do not allow
  • CRT monitors and computer power supplies to be disassembled because of the electrical charge that could be stored in the larger capacitors in those devices.
  • disassembly of computers with leaking capacitors
  • stress that capacitors are not to be bashed
Have students try to making working computers from old computers/bits.

Students get a real kick out of the disassembly of FDD, HDD and CD drives. The magnets and shiny platters in HDD are particular points of interest.

Removing the cover on a HDD and seeing it work on a live computer

Doing things with kids that are psychologically and physically challenging. eg. Taking young kids down the side of the Valley Lake from the the Potters Point Lookout (Mount Gambier). It is very challenging for kids and sometimes we get tears. The realisation that turning around and going back could be as hard as continuing on down is a hard lesson. Understanding that the only way of succeeding is for us to make it work. When we have completed this descent kids generally feel great pride in their achievement but do not want to do it again and then after a while generally/always change their minds and want to do have another go.
