Cluetrain at 20

By Stephen Downes - Stephen's Web. Cluetrain at 20
Doc Searls, Doc Searls Weblog, 2019/03/27
The Cluetrain Manifesto was an influential document when it came out 20 years ago. It proclaimed such things as "markets are conversations". I was one of the signatories when it was first released. There's a lot of discussion about what Cluetrain means, but my attention focused on a remark about how it spread. Searls says, "we didn’t do it by mass media methods. We did it by hacker’s methods. We wrote something we thought was good and put it out for review. Lots of people agreed that it was good and word spread from there." That's not exactly true. It was promoted by the Wall Street Journal and became a book. If you or I write Cluetrain, it sits there dead and unnoticed. But if the writer has connections with mass media, it becomes a mass phenomenon. More...

Methodological guide for implementation and evaluation of open e-textbook programs

By Stephen Downes - Stephen's Web. Methodological guide for implementation and evaluation of open e-textbook programs
Alek Tarkowski, Michal Sitek, Jan Strycharz, Riina Vuorikari, Jonatan Castaño Muñoz, Joint Research Centre, European Commission, 2019/03/28
This report (32 page PDF) discusses on an assessment of the impact of open e-books, "exploring the costs and savings associated with such initiatives, and on the other hand, estimating their impact on learning outcomes (e.g. exemplified as academic achievements)." The report is structured around a case study of an e-textbook initiative in Poland. More...

This Is How You Kill a Profession

By Stephen Downes - Stephen's Web. This Is How You Kill a Profession
Herb Childress, Chronicle of Higher Education, 2019/03/28
I thought at first that this would be an article by and for professors bemoaning how badly they've been treated, but in fact it looks at the academic profession from the perspective of an outsider, that is, from the perspective of the many who obtained their PhDs and didn't have the luck or connections to latch onto a proper teaching and research position at a college or university.

The great support mystery

By Stephen Downes - Stephen's Web. The great support mystery
Martin Weller, The Ed Techie, 2019/03/28
I think this is important, and that it doesn't apply only to university students. I'm talking about "a feeling of being supported – that someone out there knows about you and your studies as an individual, will look out for you, and share your highs and lows." This is the sort of thing that will get a person out of bed in the morning and keep them working on something into the evening. It's what I miss most on those days I feel alienated from my own work. It's probably the difference for many people between success and failure. More...

Facebook and Google: This is What an Effective Ad Archive API Looks Like

By Stephen Downes - Stephen's Web. Facebook and Google: This is What an Effective Ad Archive API Looks Like
The Mozilla Blog, 2019/03/28
In a recent email, Creative Commons head Cable Green wrote "CC does plan to offer an API to CC Search" I think that's a good idea. I would use that; it would allow a content creation application like gRSShopper to use CC search to find resources to link to or embed. But what should such an API look like? One person suggested IMS's Resource Search, which linked to LTI. But IMS isn't exactly open; membership has its privileges. More...

The Neuroscience of Joyful Education

By Stephen Downes - Stephen's Web. The Neuroscience of Joyful Education
This is mostly good advice - my main concern is in the tendency to lump together neuroimaging and measurement of brain chemicals, EEG measurements, glucose or oxygen use and blood flow, positron emission tomography (PET) and functional magnetic resonance imaging and more under the heading of 'brain based research', giving all such analyses equal credibility. When such studies are used to say things like "under stressful conditions information is blocked from entering the brain's areas of higher cognitive memory consolidation and storage" I think that there's a lot of interpretation going on. Just which of these electrical or chemical activities constitutes a unit of information? Not so clear. And while I think that memory is associative, as the author suggests ("Input from each individual sense (hearing, touch, taste, vision, smell) is delivered to these areas and then matched with previously stored related memories") it's not clear to me that it is the 'brain studies' cited here that tells us this.

Open-Source Platforms for Education and Equalization

By Stephen Downes - Stephen's Web. Open-Source Platforms for Education and Equalization
This is an interesting article that blends a consideration of the needs of people in less wealthy nations - based on experiences in Liberia - with the opportunities offered by things like the OLPC and the personal learning environment (PLE). "Can we stretch the concept of the PLE into an industrial-strength learning platform, costing precisely nothing to construct, offering a genuine depth and breadth of modularity and flexibility, and dependent for successful implementation only on the provision of the underlying connectivity, the wide distribution of access devices, and the level of engagement required to train teachers and learners in the use of the tools".

Rolling the Dice

By Stephen Downes - Stephen's Web. Rolling the Dice
Backfence - an experiment in online local journalism that attracted $3 million in seed money and employed as many as 25 people - is closing down. It couldn't get the readership, and more importantly, it couldn't get the advertising dollars. What does this say about the future of grassroots local journalism - and more broadly, about user-driven initiatives in general. Well, first, if you're in them to make money, you're probably in them for the wrong reasons. There are, as we see in this article, various successful local journalism projects - but none of which would ever hope to recoup a $3 million investment. And second, in order to stay small, you need to get big - to create a chain (or a network?) of similar sites, to attract national news and national advertising. Because that's where the money is.

Carlyle and the Search for Authority

By Stephen Downes - Stephen's Web. Carlyle and the Search for Authority
"The authority of the hierarchical state was being challenged, and political discourse, like religious discourse, had begun to represent authority as vested in the individuals that constituted the state rather than in monarchical hierarchy. ... Society was understood as a series of contracts among competing individuals instead of a corporate body united as a single family." Sound familiar? No, it's not Web 2.0. Rather, these sentences describe the emergence of the modern capitalist economy, the subject of Thomas Carlyle's work in the 1800s. This book - and 49 others on different topics - have now been made available for free (on PDF, sadly) by The Ohio State University Press. Good for them. Let's see more of this. More...

Having Your Cake and Eating It: The E-Framework's Service-Oriented Approach to IT in Higher Education

By Stephen Downes - Stephen's Web. Having Your Cake and Eating It: The E-Framework's Service-Oriented Approach to IT in Higher Education
"The soa [service oriented architecture] seeks to separate out the core functionalities needed by a number of different applications into a series of modular components, provided as loosely coupled services." So far so good. But then, "the functions or tasks need to be provided with an agreed-upon open interface, and the wider the agreement is on these tasks, the greater the market for such services and the lower the price." Um, hm. But then, "considerable time and effort of experienced and technically skilled people is needed to establish such agreements." Well, that's really going to favour the entities that can fund such people, isn't it? But I digress. More...
