Making Computer Science Exciting for Children – Kinderuniversität

admin 1 Kommentar

Petra is teaching at the primary school in Satteldorf. As there is no University close by we decided to have a university afternoon at school. The idea behind this (in German Kinderuniversität) is to get young children excited for scientific topics and show that research is fun. The lecture should make them curious and motivate them to ask fundamental questions.

My lecture was on principles and technologies for communication (in German) and we looked fundamentally at what information is, how it relates to probabilities, how to encode information, and what devices people used and use for communication. For me this was a very exciting experience and also showed that we (as a discipline Computer Science) should probably look more into didactic and how to communicate fundamentals of our subject in school. So far many students associated computer science with using PowerPoint 🙁 but there are interesting starting points, e.g. a German book on algorithms for school children [1].

Geocaching, Travel bug

admin Schreibe einen Kommentar
On Saturday we went for a walk and to make it more exciting we decided to look for a geocache (GCXP87, N 49° 08.775 E 010° 06.672). To our surprise it took us quite some time (10 minutes) to find it as the GPS reception was not perfect. Vivien, my daughter was excited by the idea of geo caching (I think I can anticipate some of our activities on the next weekends ;-), especially as we even found a travel bug. The travel bug is alreay on its second continent and we still discuss where we place it 😉 

Teaching in primary school, digital photography, civilization

I had a day off an was as “teaching assistant” on a school trip with the kids my wife is teaching. The trip went to a museum village (Wackershofen), which tries to preserve and communicate how people lived about 100 years ago.

On side observation was that in digital photography the limiting factor is now not anymore the memory space but the batteries in the camera. This has changed over the last 2 years – there children still selected which pictures they have to delete – now that is no issue anymore. This shows that some of the trends in pervasive computing (in this case unlimited memory) is already there…

In a project we converted manually flax into threads and theoretically into linen fabric. Some years ago I was involved in doing a similar project – with a focus on the multimedia docummentation – also with a primary school. We learned that it took a person one winter to make one piece of garment. Putting this into perspective we see an interesting trend of devaluation of physical object (cloth are one example, but applies also to high tech goods such as MP3 players) due to advances in engineering. This devaluation of physical goods led to a higher standard of living and consequently to a higher life expectancy. I wonder how further advances – especially in digital engineering will affect the quality of life…

Tagging Kids, Add-on to make digital cameras wireless

Reading the new products section in the IEEE pervasive computing magazine (Vol.7, No.2, April-June 2008) I came across a child monitoring systems: Kiddo Kidkeeper – In the smart-its project Henrik Jernström developed 2001 a similar system in his master thesis at PLAY which was published as a Demo at Ubicomp [1]. I remember very lively the discussion about the validity of this application (basically people – including me – asking “Who would want such technology?”). However it seems society and values are constantly changing – there is an interesting ongoing discussion related to that: Free Range Kids (this is the pro side 😉 The article in the IEEE Magazin hinted that the fact the you can take of the device is a problem – I see a clear message ahead – implant the device – and this time I am more careful with arguing that we don’t need it (even though I am sure we do not need it I expect that in 5 to 10 years we will have it)

There were two further interesting links in the article: an SD-card that includes WIFI and hence enables uploading of photos to the internet from any camera having an SD-slot (http://www.eye.fi/products/) – the idea is really simple but very powerful! And finally the UK has an educational laptop, too (http://www.elonexone.co.uk/). Seems the hardware is there (if not this year than next) and where is the software? I think we should put some more effort into this domain in Germany…

Not to forget the issue of the magazine contains our TEI conference report [2].
