Just solved an annoying Firefox - OSX problem

Filed under: English, Misc — frepa @ 09:00

Since I’m not particularly fond of Safari I’m using Firefox on my Mac. However, Firefox introduces a really annoying problem: each time a file is opened from the Internet it is saved on the desktop. This means that the desktop becomes extremely messy after a while.

I have now managed to solve this problem by downloading an older Safari (version 2.04) from here, launch it, and change the preferences for saving downloaded files. I changed it to the /tmp/ directory. Firefox  apparently uses the Safari setting for saving files that are opened directly from the Internet, but it doesn’t work to change the setting in Safari 3.0…

Satisfied at last:)

Ersätt slöjd med it i skolan!

Filed under: Misc, Swedish, eLearning — frepa @ 08:14

Ett problem i debatten om IT i skolan (den som knappt existerar) är att det ständigt dyker upp mer eller mindre (ofta mer) puckade förslag. Nu senast var det i Computer Sweden som det kom med det konstruktiva förslaget att ersätta Slöjd med "IT". Förslag av den här sorten är lika idiotiska som de är naiva. Det handlar givetvis inte om antingen eller, utan om både och. I just slöjd finns det dessutom massor av bra exempel på IT-användning - dessutom är dagens symaskiner nära på mer datorer än symaskiner. Inom slöjdämnet finns dessutom en av de få vettiga användningarna av POD-cast som jag har sett.

Problemet med förslag av det här slaget är inte enbart att de inte är särskilt konstruktiva, utan framförallt att de bidrar till att skapa en negativ attityd till IT bland pedagoger. Dessutom vittnar texten i övrigt om flosklig och oinitierad bild av hur man arbetar i skolan. Visst kan man diskutera skolans struktur, arbetssätt och innehåll, men då bör man samtidigt lyfta nivån på diskussionen ett antal snäpp…

CS föreslår att slöjd ersätts med informationsteknik i grundskolan. Under 2000-talet är det väsentligt viktigare att lära sig att använda en dator än en symaskin eller cirkelsåg.

På gymnasiets teoretiska program kan man argumentera för att främmande språk får maka på sig.

Datorn ersätter miniräknaren, pennan, suddgummit, linjalen och skrivmaskinen som det viktigaste arbetsredskapet. Internet ersätter boken som främsta kunskapskälla.

Med få undantag jobbar både grundskolor och gymnasier runt om i landet på ungefär samma sätt som för 20 år sedan. Ämnestablåerna är påfallande lika, samma sak med fördelningen av undervisningstid mellan ämnena.

Här kan du även rösta om eländet

Ny myndighetsstruktur för skolan

Filed under: MSU, Misc, National policy, Policy, Skolverket, Swedish — frepa @ 20:21

Häromdagen gick det ut ett pressmeddelande om att regeringen beslutat om en omorganisation av de svenska skolmyndigheterna. Föga överaskande. Bland annat slås nationellt centrum för flexibelt lärande (CFL) och Myndigheten för skolutveckling (MSU) samman med Skolverket, som i sin tur sannolikt får en ganska annorlunda roll än nu. Det blir intressant att se vad som händer med IT i skolan. Både MSU och CFL arbetar med dessa frågor, men några särskilt imponerande satsningar handlar det inte om. Det skall bli intressant att se om IT i skolan kommer att bli en av Skolverkets nya "kärnuppgifter". De signaler som varit hittills inger dock inget större hopp om att IT i skolan kommer att lyftas från dagens mycket låga ambitionsnivå.

Läs pressmeddelandet här . Där finns också utredningsdirektiven att ladda ner.

Inte helt klurigt av CETIS…

Filed under: Misc, National policy, Strange and interesting, Swedish, eLearning — frepa @ 11:51

… att kalla sig för CETIS. Med tanke på att CETIS är en, sedan länge, såväl välkänd som välrenommerad Brittisk organisation för IT och lärande så är det ganska märkligt att man väljer att kalla ett svensk nationellt centrum för tekniken i skolan för just CETIS. Nåväl, man kan inte lyckas jämt…

Massachusets skolor får MS office gratis

Filed under: Misc, Open Source, Standards, Swedish — frepa @ 22:55

Ett drag som tillsynes är lika märkligt som desperat från Microsoft. Man får verkligen hoppas att Massachusets valt Open Document formatet för att de har en genomtänkt strategi för hur man vill arbeta med öppna standarder och informationsstruktur (vilket sannolikt är fallet) och inte för att mjukvaran råkar vara gratis. Om så är fallet visar det att man inte alls har förstått vad detta handlar om på Microsoft. Det handlar inte om licenskostnader, utan om öppenhet, flexibilitet och beständighet över tid - det vill säga betydligt viktigare, strategiska egenskaper.

Vi har tidigare nämnt att delstaten Massachusets i USA tagit ett beslut att använda öppna format för informationslagring. Alla dokument skapade av delstatens anställda ska sparas i öppna format. Detta har uteslutit Microsoft office. Nu skriver Internetworld att Microsoft beslutat ge bort licenser till delstatens alla skolor. Det ska bli intressant att se om detta innebär att man ger upp kravet på öppna format eller inte.

Öppen Källkod inom Offentlig Sektor, 25-26 april 2006, Stockholm

Filed under: Misc, National policy, Open Source, Swedish — frepa @ 12:11

Konferensen Öppen Källkod inom Offentlig Sektor syftar till att ge dig som vill lära dig mer om öppen källkod, tillfälle att ta del av den erfarenhet och den kompetens som finns inom offentlig sektor.

Som deltagare kommer du att få tillfälle att ta del av kunskap och erfarenheter från andra myndigheter, verk, kommuner och Landsting som använder sig av öppen källkod, öppna standarder och öppna filformat. Vad innebär det egentligen att använda program som bygger på öppen källkod? Att öppen källkod inte är en universallösning för offentlig sektor eller att det är helt “gratis”, är de allra flesta överens om. Vari ligger då nyttan? Vilka applikationer finns tillgängliga idag? Har öppna programvaror samma prestanda, säkerhet och support som proprietär programvara? Hur ser framtiden ut? Kan öppna programvaror verkligen konkurrera med programvaror som alla användare redan lärt sig använda? Det är några av de frågeställningar som kommer att behandlas under konferensen.

Mikael Nilsson’s presentation to the IEEE/LOM meeting in Orlando in October 2005

Filed under: Misc, Semantic Web, eLearning — frepa @ 11:52

This is an important work in order to make two of the leading metadata standards move in a common direction. This work emphasizes the importance of RDF and Semantic Web technology as a mechanism for metadata interoperability.

Via the CEN/ISSS Learning Technology Standards Observatory (even though Mike is my colleague at KTH;)

In the context of the joint work item between DCMI and IEEE/LOM to develop a recommended representation of the metadata elements of the IEEE Learning Object Metadata Standard in the Dublin Core Abstract Model, Mikael Nilsson made a presentation to the IEEE/LOM meeting in Orlando in October 2005 outlining the approach and the current status.

The papers from the DC-2005 Conference are avaliable online

Filed under: Conferences, Metadata, Misc, Semantic Web, eLearning — frepa @ 10:39

The papers from the DC-2005 Conference are now avaliable online at http://dcpapers.lib.sfu.ca/, where the papers from previous DC Conferences are avaliable as well.

There are some papers that i find especially interesting from an e-learning perspective - even though they do not explicitly address e-learning, the content is applicable to e-learning with a minimum of fantasy…:

The importance for Web applications to reach all kind of potential users and customers is being stressed by companies and public sectors. The standardization initiative for Web applications, WAI and the Universal Design framework establish useful rules for building accessible applications for any kind of disabled and non-disabled users. The proliferation of Semantic Web technologies and formal ontologies offer a technological opportunity for establishing automatic and advanced methods for accessible Web applications. In this work we introduce a method for publishing Semantic Web content that establishes separated stages for content selection and its presentation, through Semantic Portal. We are applying some of those principles to a portal devoted to international affairs.

We present a national ontology development nd service framework being developed in Finland in 2003-2007. The framework is based on a set of related core ontologies, most notably on a national upper ontology based on the commonly used Finnish General Thesaurus YSA maintained by the National Library of Finland. The framework implements three ontology services by a web-based system ONKI. Firstly, ONKI supports distributed collaborative development and versioning of interde- pendent ontologies. Secondly, external cataloging and indexing systems can use ONKI as a web service for ontology-based annotations. Thirdly, information retrieval systems can use ONKI for disambiguating keyword meanings for concept-based search on the Semantic Web.

Markup is based on mnemonics (i.e. element names, attribute names and attribute values). These mnemonics have meaning, being this one of the most interesting features of markup. Human understanding of this meaning is lost when the encoder doesn’t have a good command of the language the mnemonics are based on. By "multilingual markup" we refer to the use of tags built with mnemonics in one’s own language, but still following the rules ofthe original markup vocabulary. In this paper we show the benefits of using multilingual markup vocabularies, especially in large digital library projects, and we describe our work to automate the use of multilingual vocabularies, including the translation of DC to Catalan, French, German and Spanish.

Web content accessibility for impaired people has been mainly addressed by the Web Content Accessibility Guidelines (WCAG) developed by the Web Accessibility Initiative (WAI) of the W3C Consortium. Those guidelines have proved to be good diagnostic means for testing accessibility for different types of impairments, as well as for guiding the development of accessible content. A further step would be to promote discovery of material having appropriate accessibility support, as well as the adjustment of control and display of resources to meet user accessibility needs and preferences [5]. The last two challenges have been addressed by the IMS Global Learning Consortium in the IMS-AccessForAll (ACCMD) and the IMS Learner Information Profile (ACCLIP) specifications. Although IMS has approached both goals in a learning framework, both accessibility specifications pay a special attention to impaired users’ needs. As a first step, in this paper we survey how far IMS accessibility specifications cover WCAG, and discuss the convenience of extending it to the whole WAI guidelines. Secondly, we argue how accessibility could be considered as a key issue for promoting reusability. We continue explaining why using a semantic framework (such as the MPEG-7 semantic tool, RDF or OWL) for describing textual and contextual information in a standardized manner could promote both, accessibility and reusability. Finally, we explain how some accessibility issues have been already addressed by XimetriX’s xmDex, a semantic-web Content Management System (CMS). We conclude proposing a plan to better integrate accessibility specifications and contextual description tools into that CMS.

We present a national ontology library devel-opment tool ONKI under development in Finland. ONKIÕs main goal is to support collaborative development and reuse of interdependent ontologies. It features change management and versioning of ontologies and concepts as well as a Browser component which provides the on-tology search and utilization services as Web Services.

Our eChallanges paper was awarded the “Ingo Hussla Innovation Award”!

Filed under: Misc, eLearning — frepa @ 10:33

I just got the news that the paper (Marking the National Curriculum - a New Model for Semantic Mark-up) which I presented at the eChallenges 2005 conference was awarded the Ingo Hussla Innovation Award! I am of course really happy about this and and further more - this feels like a confirmation that our model for managing semantic metadata as annotations has a great potential!

Unfortunately I was unable to attend the price ceremony as I had to leave Ljubljana early on Friday morning, but I hope that the price (that according to testimony is a beautiful piece…emoticon will be delivered to my door soon…
