Computer Tutorials

From XKCD.com - so very true.


So often someone will give me a mobile phone and say - "You're a techie/computer person can you fix this for me?"

I wish I had this in my pocket to give them.

Sometimes though some people do really want to learn, but you just don't have the time to help them every step of the way.

I learn best through a combination of tutorials, pictorials and project based or problem solving. So if you have someone who wants to learn "computers" try pointing them in these directions.

There are some good JAVA and .net tutorials as well.

http://inpics.net/index.html - I like this one becase it has step by step pictures.

Network Visualisation Tools

When I was teaching computing to middle school and high school students we didn't do much on networking. Partly because there was no real curriculum on it and partly that they had already set up LAN parties and they now knew almost as much as I did.

Times have changed and "the network" is the most important thing in a school, college, university or workplace (watch what happens when it goes does down for a day). So teaching the network is now an important part of the syllabus for computer studies.

So here are a few network Visualisation tools.

Video
Warriors of the Net - a cool animation / visualisation tool of what a Packet switch network looks like from a packet point of view.

Software
CNET - From my home town of Perth - cnet enables development of and experimentation with a variety of data-link layer, network layer, and transport layer networking protocols in networks consisting of any combination of wide-area-networking (WAN), local-area-networking (LAN), or wireless-local-area-networking (WLAN) links.Available for linux and Apple OS only.

INET framework -

GINI - GINI (GINI is not Internet) is a toolkit for creating virtual micro Internets for teaching and learning computer networks.

CLACK - Clack is a virtual network environment for visualizing network behavior and router internals.

The role of computers in education.

You would think that for someone who works in educational technology I would have a firm grasp of where technology sits in schools in Australia.... Not really. Part of the problem is things change really fast in the outside world. When I was at school the internet was not accessible (it was there though), computers were found in one place - the lab, and the only time I got to use them was for doing some basic accounting applications.

20 years later and things have changed so much outside but still stayed the same in the classroom.

Recently on echalk the denizens were discussing the role of the computer teacher and whether they will eventually be phased out. It really depends on your view but here's how I think it will go (re posted on echalk).

We have a continuum with traditional subjects.

With abstract knowledge/understanding based subjects (such as Maths and English Lit) at one end and Product/Process based subjects (English and Industrial workshop) at the other, with other subjects spaced out in between. The question here is where does computing fit in... Comp Sci down one end, Robotics at the other and game making in the middle perhaps?


Actually the more I think about it English as a subject fits computing in schools much better than the old Pen analogy.
English is used in just about every subject to a certain degree to read, process and output data, we are now moving to a point where computers are used in every subject (one hopes) to a certain degree either to read, process or output data.

English Lit=Comp Sci English=AIT English+subject=Computers+subject.

"computer" teachers will teach the first two much like English teachers share the English/ English Lit classes. Much like the support staff for literacy and numeracy there will be integrators for subjects other than computing to help teachers use the technology effectively.

Sorry this post is a bit of a ramble and I think it needs to be a bit more focused - I'll work on it.
