A day in 2061 - TEDxBrussels

What a day in TEDxBrussels- 35 speakers of a huge variety talking about the deep future, namely what will it be like in 2061.

Very inspiring, but requires lots of thinking and making connections between things that did not exist before or did not click together before (e.g. much talk about singularity, so I really had to re-fresh my memories about Kurtzweil's book, a good thing that Matt was there to help me!).

Here is my top talks:

• Leila Janah Absolutely the best "TEDTalk" of the day, just like what you would expect. She's smart, has a dream, then a vision and an idea, and able to make things happen. This talk was actually very inspiring for me, I really dig her idea and the fact that she was able to make it happen (and make it to TEDxTalks :)

• Peter Hinssen This guy had a challenge to be the 34th speaker of the day - boy, we were pretty tired at that point! He was good and able to energise us - and he talked about health care (about the most boring topic on my list). Regardless, he made it interesting and he made strong statements, like that he's the S-curve guy (as opposed to exponential curve, which was the underlying message of the remaining 30 talks).

• Rudy Rucker (video not yet online when I posted, must be coming soon) I like some of the science fiction just because it's so freaking innovative and mind-blowing. So this sweet looking, gray-haired dude turns out to be one of the early CyberPunks - and he is still totally out there! Check his predictions for year 3000 - we no longer produce things, we grow them.

• Rob Spence One particular thing about TEDTalks is that they are always sooo personal. They always tell something touchy about themselves, which after a few rounds gets pretty boring. Not so with this guy. After loosing his eye, he now replaced it with a video camera and he's talk is about pimping up humans with machines (the cyborg stuff) - really cool.

• Andrew Hassel A talk about science and biology in 2061. Very well composed and making a point about open science.

• Eileen Bartholomew Her talk is informative if you are interested in snooping out what the next X PRIZE challenge might be.

Probably any of the other videos are also worth of your 8 or 18 minutes. Some of the space travel stuff was fascinating too.

About dual licencing: Creative Commons and commercial work

Can I make money with Creative Commons?

• A FAQ answer by CC
• Creative Commons Plus (CC+), initially it's the same as dual licencing in open source world
• Example of dual licencing on Flickr with Getty image.
  
• Example of dual licencing on Magnatunes.
• Examples of making money in education
• E.g. offering print-on-demand (POD) copies at reasonable prices: MoveMeOn-book: pdf is made available for free and printed book at a price
• See a video by a commercial textbook publishing company that is leveraging CC licenses as part of their business model (Eric Frank, co-founder of Flat World Knowledge)
• A nice slideshare about Creative Commons and Open Educational Resources

Workshop: Social and Personal Computing for Web-Supported Learning Communities (SPeL 2011)

The website with the call for papers is at: http://software.ucv.ro/~epopescu/spel2011 and the schedule for SPeL 2011 is as follows:

September 7, 2011 Abstract submission
September 10, 2011 Workshop paper submission
October 5, 2011 Workshop paper notification
October 15, 2011 Camera ready paper & Registration
December 8-10, 2011 ICWL 2011 conference

The workshop follows the previous SPeL 2008, SPeL 2009 and SPeL 2010 workshops. The general topic of the workshop is the social and personal computing for web-supported learning communities.

Web-based learning is moving from centralized, institution-based systems to a decentralized and informal creation and sharing of knowledge. Social software (e.g., blogs, wikis, podcasts, media-sharing services) is increasingly being used for e-learning purposes, helping to create novel learning experiences and knowledge. In the world of pervasive Internet, learners are also evolving: the so-called "digital natives" want to be in constant communication with their peers, they expect an individualized instruction and a personalized learning environment, which automatically adapt to their individual needs.

Call: Datasets and Data Supported Learning in Technology-Enhanced Learning

************************************************

CALL FOR JOURNAL PAPERS

Special Issue on dataTEL
“Datasets and Data Supported Learning in Technology-Enhanced Learning”

International Journal of Technology Enhanced Learning (IJTEL)
ISSN (Online): 1753-5263 - ISSN (Print): 1753-5255

Deadline of submissions: 25 October 2011

************************************************

SCOPE

The prospect of great growth of open and linked data in the knowledge society creates opportunities for new insights through advanced analysis methods based on e.g., information extraction, filtering, and retrieval technologies. Educational institutions also create and own large datasets on their students’ and course activities. The analytic use of such data, however, is very limited, when considering new educational services, recommending suitable peers or content or processes or goals, and improving the personalization of learning. Nevertheless, personalized learning is expected to have the potential to create more effective learning experiences, and accelerate learners’ time-to-competence. In the educational world, the literature is sparse on how to build upon today’s very limited public datasets and how to accommodate the lack of agreed quality standards on the personalization of learning.

The special issue on dataTEL in IJTEL aims to address this issue by collecting high value research papers to develop a body of knowledge about data-based personalization of learning. So far, there is no consensus on algorithms that can be successfully applied to make reliable analyses of data in a specific learning setting. Having an initial collection of datasets, coupled with case studies of their use in TEL, could be a first major step towards a theory of personalisation within TEL that can be based on empirical experiments with verifiable and valid results.

However, data driven research confronts researchers with a new set of challenges, for instance, a lack of common dataset formats or policies to share educational datasets, a huge variety of different evaluation methods for comparing diverse personalization techniques, and new ethical and privacy issues that arise from the ability to link and mine information.

Therefore, the objective of this special issue is to explore suitable datasets for TEL – with a specific focus on recommender and information filtering systems that can take advantage of these datasets. In this context, new challenges emerge like unclear legal protection rights and privacy issues, suitable policies and formats to share data, required pre-processing procedures and rules to create sharable data sets, common evaluation criteria for recommender systems in TEL and how a data set driven future in TEL could look like.

TOPICS

Relevant topics include, but are not limited to:

- descriptions of datasets that can be used for experimentation

- descriptions of data experiments (methods or results of experiments)

- experiences with those datasets

- dealing with legal protection rights towards datasets on a European level

- privacy preservation for educational datasets

- methods of effective anonymisation of educational datasets

- management and pre-processing procedures for educational datasets

- future scenarios for educational datasets

- impact of educational datasets for learners, teachers, and parents

- mash-ups based on educational datasets

- recommender approaches that are based on educational data

- evaluation methodologies and metrics for educational recommender systems

Questions for eTwinning conference in Slovenia

Questionnaire: http://www.zoomerang.com/Survey/WEB22C8CJBYPCX/

Why we need big, authentic datasets for education?

In the world of consumer recommender systems, it is a common practise to use different data sets as benchmarks to evaluate new recommender systems algorithms (e.g. MovieLens, Book-Crossing, EachMovie data set).

In TEL, there are no standardised data sets publicly available, so that the outcomes of different recommender systems within TEL are hardly comparable.

1st workshop on ëData Sets for Technology Enhanced Learningí at the 2nd STELLAR Alpine Rendez-Vous in La Clusaz, France

SCOPE
Personalisation and analysis of user interaction data is a key approach to overcome the plethora of information in the knowledge society. It is expected that personalised learning has the potential to reduce delivery costs, to create more effective learning environments and experiences, to accelerate study time, and to increase collaboration between learners.

Recommender systems and information filtering are some of the promising technologies to support people in finding most suitable information and peer learners. They are increasingly applied in Technology-Enhanced Learning (TEL) in various European projects in order to personalise learning content and connect suitable peer learners according to their context (e.g., individual needs, preferences, and learning goals).

In the world of consumer recommender systems, it is a common practise to use different data sets as benchmarks to evaluate new recommender systems algorithms (MovieLens, Book-Crossing, EachMovie data set). In TEL, there are no standardised data sets publicly available, so that the outcomes of different recommender systems within TEL are hardly comparable.

So far, no universally valid knowledge exists on algorithm that can be successfully applied in a certain learning setting. Having such data sets could be a first major step towards a theory of personalisation within TEL that can be based on empirical experiments with verifiable and valid results.

Therefore, the objective of this workshop is to explore suitable data sets for TEL ñ with a specific focus on recommender and information filtering systems that can take advantage of these data sets. In this context, new challenges emerge like unclear legal protection rights and privacy issues, suitable policies and formats to share data, required pre-processing procedures and rules to create sharable data sets, common evaluation criteria for recommender systems in TEL and how a data set driven future in TEL could look like.

Relevant topics include, but are not limited to:

• publicly available data sets for educational systems
• dealing with legal protection rights towards data sets on a European level
• privacy preservation for educational data sets
• methods of effective anonymisation of educational data sets
• management and pre-processing procedures for educational data sets
• future scenarios for educational data sets
• impact of educational data sets for learners and teachers
• mash-ups based on educational data sets
• recommender approaches that are based on educational data
• evaluation methodologies and metrics for educational recommender systems

SUBMISSIONS
Authors are invited to submit original unpublished research as papers (4-8 pages). Demonstrations and Hands-on sessions are explicitly encouraged. All submitted papers will be peer-reviewed by at least three members of the program committee for originality, significance, clarity, and quality. Re-worked versions of accepted submissions will be published in the Interdisciplinary Journal of E-Learning and Learning Objects (IJELLO). In addition, the authors are asked to contribute short summaries of their submissions to the dataTEL group space at TELeurope to encourage early information sharing and discussion also with third persons.

Submission will be available through the EasyChair submission system:
http://www.easychair.org/conferences/?conf=datatel2011

All questions and submissions should be sent to: dataForTEL@gmail.com

WORKSHOP STRUCTURE
Based on workshop submissions, the organisers will identify 4 most pressing research challenges. For each of the challenges, we will allow around 2 hours discussion, started off through about two short submission presentations or keynotes. The final 2 hours of the last workshop day will be utilised to bring the results of the individual discussions together and to chart a vision of the future of TEL amplified by publicly available data sets.

FUNDING
Participants pay for their own travel and lodging. But we are able to fund food and lodging for 3 nights as well as the community event on Tuesday, March 29th for 10 participants. Please indicate your funding needs with your submission.

VENUE DETAILS
The second STELLAR Alpine Rendez-Vous (ARV) will take place in the French Alps in the Massif des Arravis at a beautiful ski resort called La Clusaz (hotel Alpen Roc). There will be some free time in the afternoons for TEL community building during winter activities. Funding for lodging and food will be available for a limited number of participants.

THE ALPINE RENDEZ-VOUS
This 2011 STELLAR Alpine Rendez-Vous is the second event of a series. It is organized and funded by STELLAR, a European network of excellence on learning technologies (http://www.stellarnet.eu/). The ARV is not a standard conference, but a set of independent workshops located at the same time in the same hotel. Four workshops run in parallel during the first part of the week and four during the second part. It's called "Rendez-Vous" because shared events are organized in the middle of the week (Tuesday evening) and because we set up breaks and meals in a way that promotes informal encounters between participants from the different workshops. Finally, it is called "Alpine" because it gathers scientists in the Alps, away from their workplace routines, in a place where snow is used as social facilitator."

Workshop on Recommender Systems for Technology Enhanced Learning (RecSysTEL)

Deadline extended: July 1st

This year's continuation for our previous work on SIRTEL-workshops is a jointly organised workshop called RecSysTEL in conjunction with:

• 4th ACM Conference on Recommender Systems (RecSys 2010)
• 5th European Conference on Technology Enhanced Learning (EC-TEL 2010)

It takes place in Barcelona, Spain, 29-30 September 2010

KEYNOTE SPEAKER: Joseph Konstan, GroupLens Research, University of Minnesota (USA)

AIM & TOPICS

Technology enhanced learning (TEL) aims to design, develop and test socio-technical innovations that will support and enhance learning practices of both individuals and organisations. It is an application domain that generally addresses all types of
technology research & development aiming to support of teaching and learning activities. Information retrieval is a pivotal activity in TEL, and the deployment of recommender systems has attracted increased interest during the past years.

Recommendation methods, techniques and systems open an interesting new approach to facilitate and support learning and teaching. There are plenty a resource available on the Web, both in terms of digital learning content and people resources (e.g. other learners,
experts, tutors) that can be used to facilitate teaching and learning tasks. The challenge is to develop, deploy and evaluate systems that provide learners and teachers with meaningful guidance in order to help identify suitable learning resources from a potentially overwhelming variety of choices.

The aim of the Workshop is to bring together researchers and practitioners that are working on topics related to the design, development and testing of recommender systems in educational
settings as well as present the current status of research in this area and create cross-disciplinary liaisons between the RecSys and EC-TEL communities. Overall, it aims to outline the rich potential of TEL as an application area for recommender systems, as well as expose participants to the challenges of developing such systems in a TEL context.

Topics include but are not limited to:

• User tasks to be supported by recommender systems in TEL
• Focus of recommendation in TEL
• Requirements for the deployment of TEL recommender systems
• Publicly available data sets for TEL recommender systems
• Recommendation algorithms and systems for TEL
• Transfer of successful algorithms and systems from other application areas
• Evaluation criteria and methods for TEL recommender systems

IMPORTANT DATES

• 20 June 2010: Submissions
• 16 July 2010: Notifications
• 1 August 2010: Camera-ready of accepted papers
• 29-30 September 2010: RecSysTEL Workshop in Barcelona

DATATEL CHALLENGE

Published datasets in recommender systems, such as the MovieLens and EachMovie ones, are very often used in experimental testing of new recommendation algorithms.
Very few datasets are publicly made available online for TEL applications.
Thus, it is not possible yet for TEL recommender systems' researchers to apply and benchmark their algorithms on existing, public datasets.

To this end, the dataTEL Theme Team of the European STELLAR Network of Excellence (http://www.teleurope.eu/pg/groups/9405/datatel/) is sponsoring the dataTEL Challenge: a call for TEL datasets that invites research groups to submit existing datasets from TEL applications that can be used as input for TEL recommender systems (e.g. ratings, tags, bookmarks).

The winner of the dataTEL Challenge will receive a best TEL dataset award.

ABOUT RecSys 2010 and EC-TEL 2010

The 4th ACM Conference on Recommender Systems (RecSys 2010) is the premier annual event
on research and applications of recommender technologies. It will promote a close interaction
among practitioners and researchers, reaching a wider range of participants
including those from Europe and Asia. See http://recsys.acm.org/2010/ for details.


The 5th European Conference on Technology Enhanced Learning (EC-TEL 2010) brings together technological developments, learning models, and implementations of new and innovative approaches to training and education. The conference traditionally explores how the synergy of multiple disciplines can provide new, more effective and more especially more sustainable, technology-enhanced learning solutions to learning problems. See http://www.ectel2010.org for details.

*************************************************************

What does it mean for a school to self-organise?

I was taken back to this initial idea, can schools self-organise?, after reading an article by Weston & Blain (2010) called "The end of techno-critique: the naked truth about 1:1 laptop initiatives and educational change". The reading of the article is of course related to my current work where we are running a large-scale 1:1 initiative in 6 European countries. At the end of the article, which I absolutely recommend reading, the authors conclude:

...1:1 initiatives can be fertile ground for the creation of new-paradigm schools, the schools that are self-organizing. The widespread availability of laptop computers can be a driver for the more expansive efforts that must happen in order for schools to meet the educational needs of all students....While the original mission of 1:1 laptop computer initiatives did not include shifting of educational paradigm, turning those initiatives toward the creation of self-organizing schools may be the the way forward for techno advocates and critics alike.

It's a lot about "change" in general, and especially the change that has to take place at the whole school level, not only by individual teachers, which still seem to be a trend when looking at the ICT implementations.

In our eTwinning, for example, we have more than 90 000 teachers signed up in Europe, which can be considered a good success (about 1.85% of all European teachers!). The naked truth comes out, though, when you look at the penetration by schools: about 75% of the schools have only one single teachers signed up in eTwinning, whose mission statement is "The community for schools in Europe". The community of schools build by single teachers who do not collaborate within their own schools?

So back to self-organisation - what would it mean for a school to self-organise? The hypothesis that I used for my PhD to study self-organisation within learning resource repositories was this:

The main hypothesis is that the self-organisation aspect of a social tagging system on a learning resource portal helps users discover learning resources more efficiently. Moreover, user-generated tags make the system, which operates in a multilingual context, more robust and flexible.

In this case, we could hypothesise:

The self-organisation aspect of a school helps learners learn more efficiently. Moreover, it makes the school more robust and flexible.

Bonabeau & Meyer (2001) use the following terms when talking about social insects and how they self-organise:

• Self-organisation (activities are neither centrally controlled nor locally supervised);
• Flexibility (the colony can adapt to a changing environment);
• Robustness (even when one or more individuals fail, the group can still perform its tasks).

Adapted to a school, these would be interpreted as:

• Self-organisation (activities are neither centrally controlled nor locally supervised);
• Flexibility (the school can adapt to a changing environment);
• Robustness (even when one or more individuals fail, the school can still perform its tasks).

Wow, that would be powerful, or what!?? Could 1:1 really ever help schools to self-organise? I guess this is one more reason to keep working hard on our 1:1 pilot. The next questions would be; how can a school self-organise? and what is required for a school to self-organise?

When I first started to think of this question, I was attending The Big Ideas Fest in California organised by ISKME. I was thinking of what would be A REALLY big idea for education. I think this is a pretty darn big one...

Is eTwinning socially contagious?

Last weekend I joined more than 500 eTwinners (www.etwinning.net) in the 5th annual conference that took place in Sevilla. Quite a fiesta! I co-ran 3 workshops which all had something to do with social networks, more or less. I jokingly tell teachers that I'd like them all get an eTwinning virus and spread it around when they go home. This "virus" is, of course, a good one (e.g. innovative use of web in ed.context) and it spreads through the social network that teachers have created by being part of eTwinning. From where my question: is, or can, eTwinning be socially contagious?

Often times nowadays when people talk about social networks, they actually talk about social media tools or web 2.0 stuff, where it is made easy to express your social ties and make them visible to others (can I friend you?). Underneath all that "stuff" lies the structure of the social network which is of interest to me. I consider a network

as a conduit for the propagation of information or the exertion of influence, and an individual's place in the overall pattern of relations determines what information that person has access to or, correspondingly, whom he or she is in a position to influence. A person's social role therefore depends not only on the groups to which he or she belongs but also on his or her position within those groups. (Watts, 2003, p. 48)

Moreover, Watts goes on to explain yet a different way to view the network, namely through weak ties, "which can be thought of as a link between individual- and group-level analysis in that they are created by individuals, but their presence affects the status and performance not just of the individual who "own" them but of the entire group to which they belong." - and this all leads to the new science of networks.

Duncan Watts's book Six Degrees (2003) is one of my favourite science-tainment (like edutainment) book. I always enjoy picking it up and re-reading it, I seem to understand some of the passages in a new light. Today I re-read the stuff about differences of spreading a virus and "social contagion", like a fab that spreads or cascades throughout the whole social network.

There are some similarities, like the fact that each individual has a different threshold (some get the virus easier than others) and that you have people around to spread it to ("to whom she or he pays attention to"). But "social contagion", unlike biological one, does not take place if the network is too well connected!

So when everyone is paying attention to many others, no single innovator, acting alone, can activate any one of them. ... In social contagion, remember, it is the relative number of "infected" versus "uninfected" - active versus inactive - neighbors that matter. (Watts, 2003, p. 240)

Studying fabs or innovations (e.g. the use of web in ed.context), the question is about the moment when the fab stops being a niche thing among early adapters and when it leaps to the larger general population. I too often have a feeling that eTwinning "preaches to the converted". So, I'm keen on understanding how eTwinning can step out of being a nice of early adapters and get the others "contaminated". Someone aired a good comment in the conference, we should not take eTwinners as a representative sample of educational community in general.

Step one: who is infected?


I ran a few analysis to get a better picture. It's hard to find the number of schools or teachers in all eTwinning countries. After some digging I found OECD's Stat extracts which has lots of good data, and was able to find the number of teaching staff for 23 out of 32 countries (close to OECD's definition for EU19). I think that's a pretty good proxy to go by, however, not sure how accurately our data aligns with them. I used the date as described in the image for 2007.

The data says there was 6 210 411.57 teachers (I love the 0.57 teacher!) working in those countries, out of which 76 367 have registered in eTwinning by this date. On average, each country has 1.83% of their teachers infected by the "eTwinning virus", median was 1.42%. The countries above median in descending order are: Estonia, Iceland, Slovak Republic, Czech Republic, Slovenia, Finland, Greece, Poland (still above average, too!), Spain, Luxembourg, Portugal and Sweden. Are you surprised? I am a bit...

The countries below median were: the United Kingdom, Turkey, Norway, Netherlands, Italy, Ireland, Hungary, Germany, France, Belgium and Austria.

Well, my question is not about the success of eTwinning initiative itself, but it's more about understanding what are the conditions (globally and locally), what are the individual thresholds and when can we expect the cascading effect to take place (it's all about one or more vulnerable neighbors who have one or more vulnerable neighbors who have...).

These are typical questions that people interested in the new science of networks ask, and I want to know more how it happens within educational context. I think eTwinning is a good virus to study that!

We've just stated the TeLLNet project with some top-notch partners, so I'm looking forward to dwell into this problematic later again!

From what are big educational ideas made?

Silicon valley is an iconic example when people talk about innovation. To breed innovation, it's important to remember that it's not only about individuals with ideas, but about the right conditions, like a "large number of cutting-edge entrepreneurs, engineers and venture capitalists" (wikipedia), in the case of the Valley. On top of that, you add a flavour of Californian sea, sun and wine, and you season it with a bit of pioneering attitude, and voila!

I'm today in California for theBig Ideas Fest.

The three-day Big Ideas Fest is an immersion into collaboration and design with the focus on inspiring and modeling cutting-edge thinking in K-20 education.

The programme and the names of speakers are pretty impressive! I think there will be an interesting buzz in the air, as the event brings together cutting-edge educationalists, "doers and shakers" who are interested in brainstorming on big ideas that are needed to move education in the right direction. The session is starting in a few seconds, so I'll be reporting back later.

Future privacy and security resaerch challenges in online social networks

I attended this workshop a couple of days ago. It was an interesting mix of ppl with different backgrounds; computer scientists, researchers, lawyers, some practitioners & users like a SN provider, some artists who run social network services, and my interest was of course teachers' social network services like our eTwinning platform (more than 70000 teachers).

I enjoyed the keynote by Ronald Leenes from Tilburg University. A few projects that he mentioned, PrimeLife (Bringing sustainable privacy and identity management to future networks and services) and BROAD (Broadening the Range Of Awareness in Data protection).

EUN is now running a http://www.dataprotectionday.eu/ campaign, here is my favourite film about it!

Most scholarly opponent - PhD Ceremony in OUNL Nov 13 2009

It's pretty exiting to prepare for the PhD ceremony. There are all kinds of little things to think about. I've never gotten married, but it sure sounds like the same thing. In the Netherlands, for example, we need to have paranymphs at the PhD ceremony.

Yes, I know, it sounds like I need to have two dwarfs by my side there, but apparently they are like a bride's maid or a best man. With a twist that in case there was a heated fight between me and the opponents during the defence, the paranymphs would defend me with swords. Or, you know, something similar. So far, all what I've seen is that they hand over a class of water, but - we've ain't seen nothing yet..

Another thing is the manner of speech, I am, for example, to address the members in my committee by saying "most scholarly opponent", if they are a professor, otherwise just "scholarly opponent" is fine. And they call me "esteemed candidate". Pretty theatrical :)

Finally, I needed to prepare 10 statements in advance, they are called stellingen. 4 of them are about my thesis and the rest are more general (some can even be a bit funny, see #10). But in general, they all should be something that I can defend.

The purpose of this is that when the opponent has not had time to read my thesis and come up with a question, they can read one from the list. This way they can have a well formulated question to ask. My advantage - I can prepare for it in advance. Kind of a funny game! It seems to me that the more bold the statement is, the better chances there are that one of the opponents reads it out loud. Let's see...

1. A learning resource portal in a multilingual context can be made more robust and flexible by interrelating conventional metadata and social tags. (this thesis)

2. Socal tags, represented as a triple (user,item,tag), open more sophisticated avenues for resource discovery across contexts, especially when it applies to cross-language and cross-country discoveries. (this thesis)

3. The triple (user,item,tag) can be used as a parameter to measure links between cross-language content that reside on heterogeneous repositories. It can be created a posteriori to content creation and link-setting, and it can be used to support and enhance a new type of link-following behaviour by end-users. (this thesis)

4. The discovery strategies based on Social Information Retrieval (SIR) methods allow users to spend less effort in finding relevant resources on a multilingual portal. (this thesis)

5. The notion of learning resources as content is too limiting.

6. Even if the current trend in information seeking behaviour is the Web, interpersonal ties still drive and support information seeking. Social search should be considered beyond individual’s Web-behaviour.

7. While studying the impact of new information and communication technologies on education and attainment, studying their out-of-school use should be considered as important as their in-school use.

8. In Technology-Enhanced Learning, like in other lo-fi high tech, the next best thing is “good ‘nuf” for most users.

9. Languages both unite and divide people.

10. Anyone involved in decision-making for educational purposes should read science fiction.

Educational take - danah boyd: American Teens & Social Media

danah boyd has put something really important in words in this little video, it's related to the use of social media (applicable to all ICTs and mobile technologies) in education. If in a hurry, fast-forward to about 5.30 of the video:

Teens need to know boundaries, norms and how society works, and this should be taught through using social media, i.e. the tools that they use anyway .

The reason that "because kids are doing it" it not a good reason to start teaching about social media in schools. "Pedagogy and understanding of the tools, are two key pieces of knowledge that teachers must have before entertaining the idea of bringing social media into the classroom. Information sharing is relevant to education..."

A valid point made for teachers continuous professional development!

Impact of ICT use on educational performance

The question the top-dog politicians nowadays ask is the impact of ICT on educational performance. Especially in the school sector, this has been the trendy question since a few years, when the policy makers realised that they want to see some return on their investment (i.e. all the hardware put in schools). My favourite EUN report on recent research is The ICT Impact Report (01/2007).

This week at the OECD's New Millennium Learner conference South-Koreans presented another interesting study towards this direction. Prof. Heo's presentation is available here, check the pages from 20 onwards for the results. The study included 10% of the 10th graders in South-Korea (1071 students, random sampling). The design of the study looked at the use of ICT

• Place: in-school and out-of-school use of ICT
• Purpose: learning vs. entertainment use of ICT
• Context: individual use vs. social use of ICT

Educational performance was divided into:

• Cognitive domain
• Affective domain
• Socio-cultural domain
  

Significant impact was found on educational performance with:

• Out-of school ICT use
  
• ICT use for learning
  
• ICT use in individual context

Note, in-school use did not yield any significant impact :/ More interestingly, out-of-school use of ICT for learning purposes had a positive correlation (r=0.520, p= 0.00) with cognitive domain of educational performance, which shows good news for informal context of learning.
