Devedžic's Semantic Web and Education, reviewed by Bürger

Source: elearning-reviews

elearning-reviews is an impressive, well-organised printing-friendly web site, from the Swiss Centre for Innovations in Learning. It "provides those interested in research on elearning with concise and thoughtful reviews of relevant publications".

This review by Tobias Bürgerof Vladan Devedžic's 2006 "Semantic Web and Education", does just that. Concluding paragraph:

"This book also shows that the marginal importance (compared with e. g. prior learning experiences) of “general” learning styles (as it was shown in research) is still not recognised in the world of artificial intelligence and computer science; they still deal with the idea of several cognitive styles and the possibilities for adaptation of e-learning materials. By the way: We were surprised that the different ways of reasoning seemed not to be important to Vladan Devedižic. Some could say that we should not be so harsh with our comments on this book, because it is one of the first longer publications on this topic (published 2006). Yes, we agree – but we would not have been as harsh, if there were not some very interesting older publications, where we find a deeper understanding of what learning and education is and could mean in the Semantic Web. Nevertheless, we will use this book and can recommend it as a standard work about education and the Semantic Web with the clear strength in an overview about relating technical concepts."

Felling the towers - 24/8/2008

Sheffield's landmark 70 year old cooling towers were demolished at 02.00 GMT today.

Links to video and BBC web site description of the towers falling.

[Previously updated 27/9/2007]

These two cooling towers above are on the edge of Sheffield, where I live, in South Yorkshire, England. They are next to the vast Meadowhall shopping centre, and the Tinsley Viaduct of the M1 motorway. Taking a leaf out of Soweto's book (see also the picture on the right), there is a campaign to turn them into massive works of public art to reflect what Sheffield is now: "green, creative and different".  Funds are stacking up to make the project a reality. The Channel 4 TV company is committed to the idea.  But there is a problem. Eon, owners of UK electricity company Powergen and the towers, wants to demolish them.

Coroner calls for Government action on sleep apnoea

Today my sister and brother in law issued a media release stemming from last month's Inquest into the death of their son Toby. Regular readers of Fortnightly Mailing may remember from a long post I wrote in October 2007 that my 25 year old nephew was killed 2 years ago on his way to work in Liverpool. His car was waiting in a morning rush hour queue on the M62 motorway approaching the Rocket Interchange. The queue was hit from behind by a heavy goods vehicle and Toby’s car was crushed. The driver of the HGV had fallen asleep at the wheel, and was later diagnosed to be suffering from Obstructive Sleep Apnoea (OSA).  When we investigated OSA we found serious weaknesses in the way that the condition is controlled by Government, by the road haulage industry, and by General Practitioners.

Following the Inquest, the Coroner issued a Rule 43 Report to the Lord Chancellor, calling for major changes in the way that sleep apnoea amongst lorry drivers is dealt with. The media release [137 kB PDF] provides full details, and includes the Rule 43 Report itself, as well as the bulk of a fascinating and comprehensive report to the Inquest by Dr Dev Banerjee, who is Consultant Respiratory and Sleep Physician at Birmingham Heartlands Hospital.

The Coroner's Rule 43 Report calls for the following:

• regular medical screening for all lorry drivers;
• amendment of the DVLA Medical Examination Report form to improve identification of undiagnosed sufferers from OSA;
• fast track medical assessment of commercial drivers involved in road traffic collisions;
• better education of all drivers on the dangers of tiredness when driving, in the same manner as drink-driving campaigns;
• better education of commercial drivers to make them aware that a diagnosis of OSA is almost certainly not the end of their livelihood as a driver.

Under new rules that came into force on 17 July, the Lord Chancellor is required to respond to a Coroner’s Rule 43 Report within 56 days.

European e-Inclusion Awards - closing date 12 September

The European Commission has launched the first ever European e-Inclusion Awards. The Awards will "celebrate the best and most imaginative uses of Information and Communications Technology to reduce digital and social exclusion". The closing date for applications is 12 September. Excerpt:

"The European e-Inclusion Awards are open to organisations in the public, business and voluntary sector or civil society. There are seven competition categories:

• Ageing well
• Marginalised Young People
• Geographic Inclusion
• Cultural Diversity
• Digital Literacy
• e-Accessibility
• Inclusive Public Services"

How to stop email overload

Nice clear explanation by Anand Rajaraman about how his 30+ person business (Kosmix - a company that is developing a pretty impressive topic-focused search engine - example 1; example 2) uses blogs, wikis, and instant messaging for internal communication. Plenty to emulate there for many organisations.
 

Court in Texas denies Blackboard's motion for contempt against Desire2Learn

According to Desire2Learn, Blackboard Inc.'s forcefully worded motion for contempt against Desire2Learn was denied by the court in Beaumont, Texas, yesterday. Blackboard has apparently failed to convince the court that the changes made by Desire2Learn in Version 8.3 of its VLE are "only transparently cosmetic", and "do not design around the claims of the ’138 patent".  Blackboard had sought explicitly coercive damages in its motion for contempt:

"Blackboard suggests that for each day following this Court’s order that Desire2Learn uses, sells or offers for sale version 8.3 or associated services, Desire2Learn should be ordered to pay Blackboard $23,000.00. No litigant can be permitted to simply choose to pay a sanction and continue to violate a federal district court’s injunction, however. If, after five days, Desire2Learn continues to defy the order, the daily sanction should double to $46,000.00. And if, after five more days, that sanction is insufficiently strong coerce Desire2Learn into compliance, it should double again. The sanction should continue to increase until Desire2Learn complies."

so the failure - even if it is only a temporary failure - must come as a relief for Desire2Learn. Expect more on this in the next few days on the Desire2Learn and/or on the Blackboard patent information pages, especially once the full judgment from the case is published. Conceivably this may have a sting in its tail for either company.

US National Academy of Engineering selects "Advance personalized learning" as one of 14 grand challenges for engineering

Source: US National Archives

Advance personalized learning is in pretty august company as one of 14 grand challenges for engineering (alongside, for example, Make solar energy economical, Provide access to clean water, Prevent nuclear terror, and Provide energy from fusion) chosen earlier this year by a panel of luminaries including Ray Kurzweil, Alec Broers , and Google's Larry Page. (The picture, from the Grand Engineering Challenges web site, is of a one-room 1950s US school-room  where lessons were individualized, since classes included children of different ages.)

There are two short video interviews from panel members: Calestous Juma (Professor of the Practice of International Development, Harvard University), and Wesley Harris (Professor of Aeronautics and Astronautics, Massachusetts Institute of Technology).

The rubric about the personalized learning challenge is interesting for the way challenge is posed; and the fact that personalisation is seen as a long-term challenge - on a par with fusion power - does act as a useful caution to the current UK policy emphasis on achieving extensive personalisation using technology right now.

Why are researchers citing fewer papers than ever?

Via this article about James Evans's work in the Economist, referring to Electronic Publication and the Narrowing of Science and Scholarship, published yesterday in Science, I came across this (poorly produced!) National Science Foundation short video of Evans discussing why researchers cite fewer research papers despite having access to more. Blurb:

"Thanks to the Internet, scientists now have access to an astonishing number of research papers, scholarly journals and other papers. But according to new research conducted by James Evans, a professor sociology at the University of Chicago, researchers are actually citing fewer papers than ever, and they tend to cite newer papers that are also cited by many of their peers. In this interview, James discusses what got him interested in the topic, how he conducted his research and what he believes are some of the implications of this trend."

The key cause of the change - which Evans alludes to towards the end of the interview - is surely "search", and in particular the ranking technologies that search engines employ: once a paper on the Web has a lot of citations from articles also on the Web, then that paper's search ranking rises; if its search ranking is high it is more likely to be cited.  You wonder what account is being taken of this by proponents of metrics-based assessments of research excellence.

Becta-funded "Schools Open Source Project" is looking for serving teachers for its advisory committee

The Schools Open Source Project is looking for practising senior teachers to serve on the project's advisory committee. The committee will meet 3 or 4 times each year, receive reports from the project team and provide advice and guidance to ensure the service meets the objectives of the project and its customers. Here is an excerpt from the project web site:

"The Schools Open Source Project is a Becta funded initiative to help schools with awareness, adoption, deployment, use and ongoing development of Open Source Software. A number of schools are already realising the benefits of OSS within their ICT strategy. This project will work to share their experiences along with good OSS practice from other sectors with the wider community of educational practitioners, including teachers, decision makers and IT specialists.

From September 2008, we will provide an authoritative, informative and impartial website that will raise awareness of how OSS can be used to enhance teaching and school infrastructures. The project will then develop and support a community of practice that engages those who are currently using OSS and welcomes and supports new members."

A welcome development, but you are left wondering what the link is between this Becta-funded activity, and JISC's Open Source Software Advisory Service. How will these two services avoid duplication of effort? How can the knowhow they are each developing be shared? Why not have a single cross-sectoral service? Readers with insights are welcome to comment below, or to write to me directly and I will summarise.
