David Kolb has produced a hypertext essay on the nature of modern spaces in cities called Sprawling Places
This hypertext has 100,000 words, 600 pages and 1,000 images
The work is multiply linked and threaded by a number of outlines or themes
It is possible for two (or more) people to ‘read’ the work in quite unconnected ways [...]
A BBC News article reports a survey by the Institute of Advanced Motorists into perceived driving risks based on a sample of 700 drivers. The survey finds differences based on gender and age regarding the risks.

“Alternatives to the ‘monolithic’ VLE, including public domain and open source VLEs, are emerging strongly. Some, such as ‘blogs’ and ‘wikis’, are completely different avenues to electronic publishing and collaboration and can be relatively inexpensive. Although UK universities seem to be surprisingly reluctant to spend less rather than more money on technology solutions, one can [...]

Seems to have a good range of patterns including polar and log-lin. The metric rulings are on the right, and seem short of smaller divisions (i.e. 20mm/2mm isn’t there). The isometric papers could come in handy for 3-d drawing!

The Becta report based on an ‘oportunity’ sample of schools using Open Source software to varying extents compared to schools using commercial software (i.e. Windows servers, desktops and Office) has now been published (publication was delayed during the General Election).

Survey! Question! Read! Recite! Review! is a reading framework that is suggested for University students.
As I find myself teaching a reading / writing based subject (Forensic ICT) to a group of sixth formers and some adults in the evening, I come up against problems with reading, summarising and writing. I have been ‘scaffolding’ complex readings [...]

Students searched for information about Adrian Lamo, the ‘homeless hacker’
Then we read page 3 and 4 of Marc Roger’s essay A New Hacker Taxonomy
Students were invited to analyse aspects of Lamo’s ‘career’ using Rogers’ roles
Disagreements! Arguments focussing on what the roles meant! Useful!
Lamo’s minimalist home page provides an example of embedded hypertext – [...]
“On the Friday evening of April 25, 1986, the reactor crew at Chernobyl-4, prepared to run a test the next day to see how long the turbines would keep spinning and producing power if the electrical power supply went off line. This was a dangerous test, but it had been done before. As a part [...]
Zeldman has this link to a Web designer called Joe Clark. Ten Questions for Joe Clark is a thought provoking piece in the style of a pop mag interview. Should get Web design students at least thinking about the issues. Mr Clark links to Techniques for Accessible HTML Tables

Dmitri Baltermans was an ‘official’ Soviet photographer. His war photographs are bleak and direct. Mark Bernstein quotes Lilia Efimova about the media coverage of the war memorial on May 9th in Moscow.
“And the irony is that level 3 is what employers are looking for,” she says. “If we are seriously trying to support our local community through economic regeneration, then we have to kit them out with the best qualifications – which, in London, is level 3 and upwards.”-Barbara Field, Principal of Harrow College, quoted in [...]
Timetabling (that three dimensional jigsaw puzzle) is occuring and it looks like I’ll be teaching a GCSE Maths course next year. Expect a week by week puzzle page. Hot Potatoes looks like the way to go with quizzes and puzzles delivered through a blog like WordPress with ‘future posting’. Animated formulas (see below) might be [...]

The Natioanl Library of Virtual Manipulatives for Interactive Mathematics is a Web site with a large number of Java applets that invite students to explore Mathematics problems. ‘Manipulatives’ is the US term for things like Cuisenaire rods and Dienes blocks.

The GIMP is a powerful open source image editing application that works on both Windows and Mac OS X platforms. I can edit images in the same application at work (Win 2000) and at home (Mac OS X).
There is a simple graphical construction that you can add to estimate a more accurate value for the mode of a grouped frequency distribution (see the red lines on the sketch graph below).
Can you write a formula for the value of the mode estimate in terms of the locations of the bar boundaries and the [...]
“Within three months of opening up of the Internet kiosk, it was found that the children, mostly from the slum, had achieved a certain level of computer skills without any planned instructional intervention. They were able to browse the Internet, download songs, go to cartoon sites, work on MS Paint. They even invented their own [...]
Edward Lorenz was using a primitive computer (it was 1963) to numerically integrate an apparently simple set of coupled differential equations. The computer worked to 6 decimal places and printed out each line to 3 places. Restarting a run, he noticed that the trace started looking similar but became slowly different to a previous run [...]
