Enclosing not so much the commons, but space itself.

I first became ware of the importance of intellectual property law and custom after reading James Boyle’s ‘Shamans, Software and Spleens’. I had been completely unaware of how important the institution of private intellectual property was, and how destructive it frequently was of human advance. Of course, it was not meant to be this way. Boyle’s book is dense but funny, and he lambasts the contradictions in copyright law, the tortured logic in the bizarre attempts to explain why blackmail and insider trading are illegal, and the craziness that surrounded patenting DNA and what you can do with my spleen once you once removed it. As Cory Doctorow commented, about another of Boyle’s books, ‘Bound by Law’, “Copyright, a system that is meant to promote creativity, has been hijacked by a few industrial players and perverted. Today copyright is as likely to suppress new creativity as it is to protect it.” It was reading Boyle that led me to write an essay in the Lancet on how the ease or difficulty of assigning IPR distorted medical advance.

But this takes the ticket, I am quoting from Stephen Downes commenting on this:

This is a funny story with a surprise inside. The funny part is the artwork: an artist created glass blocks exactly the dimensions of a FedEx box and then shipped them in those boxes, producing unique art out of the cracks and breakage that resulted. The surprise is that it turns out that Fed Ex has corporate ownership over that space. “There’s a copyright designating the design of each FedEx box, but there’s also the corporate ownership over that very shape. It’s a proprietary volume of space, distinct from the design of the box.” Now I’m afraid I might accidentally violate FedEx’s ownership over that specific shape should I decide to, I don’t know, create my own mailing box.

Not so much enclosing the commons, but space itself.

educational fMRI and diagnosing cars with a thermometer over the bonnet

by reestheskin on 13/01/2017

At the risk of raising the ire of many researchers, I should note that I am not basing my assessment on the rapid growth in educational neuroscience. You know, the kind of study where a subject is slid into an fMRI machine and asked to solve math puzzles. Those studies are valuable, but at the present stage, at best they provide at most tentative clues about how people learn, and little specific in terms of how to help people learn. (A good analogy would be trying to diagnose an engine fault in a car by moving a thermometer over the hood.) One day, educational neuroscience may provide a solid basis for education the way, say, the modern theory of genetics advanced medical practice. But not yet.

Keith Devlin, talking sense — again. I want to believe the the rest of the article but, worry it may not be so. But it contains some gems:

Classroom studies invariably end up as studies of the teacher as much as of the students, and often measure the effect of the students’ home environment rather than what goes on in the classroom.

This just adds to the problem that Geoff Norman (DOI 10.1007/s10459-016-9705-6) and others have talked about in course evaluations, namely that many studies — even accepting of the limitations outlines above — are riddled with pseudoreplication.

And:

What is missing is any insight into what is actually going on in the student’s mind—something that can be very different from what the evidence shows, as was dramatically illustrated for mathematics learning several decades ago

But, like many outwith medicine, I think he puts too much store by the robustness of the RCT approach — even with digital tools to allow large scale measurement. RCT: ‘randomised, confounded and trivial’, as has been said before (Norman).

Big data: more big money than big ideas

Trouble is, the intrusions cannot be ignored or wished away. Nor can the coercion. Take the case of Aaron Abrams. He’s a math professor at Washington and Lee University in Virginia. He is covered by Anthem Insurance, which administers a well­ness program. To comply with the program, he must accrue 3,250 “HealthPoints.” He gets one point for each “daily log-in” and 1,000 points each for an annual doctor’s visit and an on-campus health screening. He also gets points for filling out a “Health Survey” in which he assigns himself monthly goals, getting more points if he achieves them. If he chooses not to participate in the program, Abrams must pay an extra $50 per month toward his premium.

Abrams was hired to teach math. And now, like millions of other Americans, part of his job is to follow a host of health dictates and to share that data not only with his employer but also with the third-party company that administers the program. He resents it, and he foresees the day when the college will be able to extend its surveillance.

Cathy O’Neil, ‘Weapons of Math Destruction’, excerpt on Backchannel.

This sort of thing is going to be all over education and our private lives. Big data masquerading as big ideas, or just ‘big money’. Its just because ‘we care’.

Great post by Bryan Alexander, titled ‘ A Devil’s Dictionary of Educational Technology’. If you work in it, you will recognise it. I will start off with my favourites

Powerpoint, n. 1. A popular and low cost narcotic, mysteriously decriminalized.

YouTube, n. The ideal educational technology: everyone likes and uses it, it’s reliable and free, and neither you nor anyone you know has to support it.

Here are a few more:

Active learning , n. 1.The opposite of obedience lessons.

Asynchronous, adj. The delightful state of being able to engage with someone online without their seeing you, while allowing you to make a sandwich.

Best practice, n. “An educational approach that someone heard worked well somewhere. See also ‘transformative,’ ‘game changer,’ and ‘disruptive.’” (by Jim Julius)

LMS, n. 1) A document management system, whereby a faculty member can transfer a single document to his or her students. Curiously overpowered for this purpose, nevertheless universally deployed.

2) A good way to avoid legal notices about copyright.

3) The graveyard of pedagogical intentions. A sump for IT budgets.

Nice procrastination piece, or reality check, depending on whether you teach or you deliver teaching.

Techno-pessimism, MOOCs and market failure in med ed

by reestheskin on 23/10/2016

Attention: Some slipping of the causal nexus is evident.

An article in the Economist reviewing, or at least discussing, a couple of books about the rate of innovation caught my eye,  in particular a snippet that I will expand on below. The books were “The Rise and Fall of American Growth” by Robert Gordon, and the “The Innovation Illusion” by Fredrik Erixon and Bjorn Weigel. I haven’t read either, but enjoyed a review of the Gordon book in the NYRB by Willian Nordhaus. Based on my reading of the Nordhaus book review the issue is that the rate of innovation and productivity is declining — we are not hurtling towards any singularity — and that the century of out of the ordinary innovation was 1870 to 1970. Here is Nordhaus:

Gordon focuses on growth in the United States. Living standards, as measured by GDP per capita or real wages, accelerated after 1870. The growth rate looks like an inverted U. Productivity growth rose from the late nineteenth century and peaked in the 1950s, but has slowed to a crawl since 1970. In designating 1870–1970 as the special century, Gordon emphasizes that the period since 1970 has been less special. He argues that the pace of innovation has slowed since 1970 (a point that will surprise many people), and furthermore that the gains from technological improvement have been shared less broadly (a point that is widely appreciated and true).

In the Economist article, we read:

The figures from recent years are truly dismal. Karim Foda, of the Brookings Institution, calculates that labour productivity in the rich world is growing at its slowest rate since 1950. Total factor productivity (which tries to measure innovation) has grown at just 0.1% in advanced economies since 2004, well below its historical average.

I do not find this view strange. Medical advance is slowing, not accelerating. Medicine was transformed between 1940 and 1970, but the rate of new discovery has slowed. There is more data , more activity, and more scientists, of course. And a lot more hype and university press officers. Just less advance in comparison with what went before. The same is true about university education, too.

Criticisms of these views include questions about the data used to support the various arguments. In the Economist piece, the ‘techno optimists’ make two criticisms. The second is that the ‘techno’ revolution hasn’t really started yet, but it is the first one that caught my eye:

The first is that there must be something wrong with the figures. One possibility is that they fail to count the huge consumer surplus given away free of charge on the internet. But this is unconvincing. The official figures may well be understating the impact of the internet revolution, just as they downplayed the impact of electricity and cars in the past, but they are not understating it enough to explain the recent decline in productivity growth.

Paul Mason elsewhere uses the example of Wikipedia:

Wikipedia is a non-market form of activity—it’s a $3bn hole in the advertising world.

Now bringing this back to my own little world, I am intrigued by how the battle between, on the one hand, free or OER, and on the other, books or content, you have to pay for, will work out. I touched on this in an article on teaching and learning several years ago, and one of the reasons I wrote the freely accessible textbook of skin cancer, www.skincancer909.com* was out of frustration at the poor quality of dermatology textbooks targeted at medical students. When I surveyed medical students a large fraction did not buy a dermatology textbook, yet it is clear that the university did not provide suitable alternatives, nor was the university able to provide reasonable online alternatives. Now, I do not believe that free is always best, nor do I think that the endgame is anytime soon. But I do believe content is critical, and despair at how the med ed (medical education) world largely ignores it. But there are amazing commercial books out there — think Molecular Biology of the Cell for instance — and there is a battle to be waged about whether you invest large amounts of money in producing material used by many, or continue with the traditional approach taken by universities (those ‘bloody PowerPoints’ and dull lectures, all done on a shoestring budget).

Woodie Flowers touched on cognate issues in a critique of MOOCs and MITx

In the United States, our “education” system is choking to death on a failed training system. Each year, 600,000 first-year college students take calculus; 250,000 fail. At $2000/failed-course, that is half-a-billion dollars. That happens to be the approximate cost of the movie Avatar, a movie that took a thousand people four years to make. Many of those involved in the movie were the best in their field. The present worth of losses of $500 million/year, especially at current discount rates, is an enormous number. I believe even a $100 million investment could cut the calculus failure rate in half.

The criticism stings because Flowers is an educational legend (it also speaks to MIT that they broadcast such critiques of their own activities). Here is Flowers again:

Properly designed new media materials can improve K–12, residential, distance, and life-long learning. In their highly developed form, these learning materials would be as elegantly produced as movies and video games and would be as engaging as a great novel.

I do not know how all of this will work out. I am intrigued by the view that we might be underestimating ‘production’ because much of it is free, but I think we are seeing real market failure, both from the commercial world and from the universities.

* Skincancer909 is due an update, and I am aiming for early 2017.

First of all a link to an interview with Joe Ito and Barack Obama. The latter you may have heard about, but Ito is the head of the MIT media lab. Interesting, in that he has no higher ed qualifications. But then again, Jacob Bronowski, was deemed ineligible for a Chair in the UK because he appeared on the radio and TV. But can you really imagine this sort of thing from the bunch of tyros we call a UK government?

The second, an example of how sometimes it seems that scholarship is more in evidence on the web than within the walls of the academy. You think you understand the scurvy story, or how medical progress happens. Read on.

Edtech, Edinburgh and the blackboard.

by reestheskin on 17/10/2016

“In the early 1800s, slate blackboards represented change. For centuries, students had used handheld tablets of wood or slate. Teachers moved about their classrooms, writing instructions and inspecting students’ work on individual slates. When the Scottish educational reformer James Pillans became the rector of Edinburgh High School, in 1810, his use of a blackboard was revolutionary. He explains in an 1856 memoir, Contributions to the Cause of Education:

I placed before my pupils, instead of a crowded and perplexing map, a large black board, having an unpolished non-reflecting surface, on which was inscribed in bold relief a delineation of the country, with its mountains, rivers, lakes, cities, and towns of note. The delineation was executed with chalks of different colours.

Widely recognized as the inventor of the blackboard, Pillans doesn’t specify how he constructed the apparatus……Pillans used his innovation to teach Greek as well as geography, noting,

The very novelty of all looking on one board, instead of each on his own book, had its effect in sustaining attention.”

Sounds familiar.

Distance learning and the unbundling of education approaches its 200th birthday

by reestheskin on 02/10/2016

Interesting post from Tony Bates on the history of distance learning, and the University of London External Programme, which started in 1828.

Unfortunately I have no knowledge of the individuals who originally created the University of London External Programme back in 1828. It’s a worthy research project for anyone interested in the history of distance education.

I was once (mid-1960s) a correspondence tutor for students taking undergraduate psychology courses in the External Programme. In those days, the university would publish a curriculum (a list of topics) and provide a reading list. Students could sit an exam when they felt they were ready. Students paid tutors such as myself to help them with their studies. I would find old exam papers for the course, and set questions for individual students, and they would send me their answers and I would mark them. Many students were in British Commonwealth countries and it could take weeks after students sent in their essays before my feedback eventually got back to them. Not surprisingly, in those days completion rates in the programme were very low…

But I am fascinated by (and was ignorant of) the following:

Note though that teaching and examining in the original External Programme were disaggregated (those teaching it were different from those examining it), contract tutors were separate from the main faculty were used, and students studied individually and took exams when ready. So many of the ‘new’ developments in distance education such as disaggregation, self-directed learning, and many of the elements of competency-based learning are in fact over 150 years old.

Someone Is Learning How to Take Down the Internet

“Over the past year or two, someone has been probing the defenses of the companies that run critical pieces of the Internet. These probes take the form of precisely calibrated attacks designed to determine exactly how well these companies can defend themselves, and what would be required to take them down. We don’t know who is doing this, but it feels like a large a large nation state.”

Big data exceptionalism

by reestheskin on 19/05/2016

Comments are disabled

This comment (and phrase) from Bruce Schneier struck a chord with me.

NYU professor Helen Nissenbaum gave an excellent lecture at Brown University last month, where she rebutted those who think that we should not regulate data collection, only data use: something she calls “big data exceptionalism.” Basically, this is the idea that collecting the “haystack” isn’t the problem; it what is done with it that is………Under this framework, the problem with wholesale data collection is not that it is used to curtail your freedom; the problem is that the collector has the power to curtail your freedom. Whether they use it or not, the fact that they have that power over us is itself a harm.

Of course, as Alan Kay said, we need ‘big ideas’ rather than assuming ‘big data’ will do our thinking for us. This is not to deny that large data sets are not useful, nor that they do not allow you to answer questions, you might not have been able to do so before. But A/B testing only gets you so far. And beware technicians who want to mould nature to their method, not vice versa; or change what meaningful consent means.

Every Episode of David Attenborough’s Life Series, Ranked

Nice paean to David Attenborough, with the above title. There was a time when it is said that people like Jacob Bronowski were denied academic advance in the UK because he has appeared on TV. How the world of impact has changed. But just as many of us get excited by the power of the web to broaden access and change higher-ed, we should remember that some of the most potent educational agents of the twentieth century, got there before us. I am thinking cheap paperbacks (Pelican); the BBC; the OU on the BBC; and the movement throughout the 1930’s and beyond for prominent academics to reach out to that large part of the population who had been denied access to higher ed. If we want to build large scale resources for higher ed, we could do worse than look at the extraordinary teams the BBC put together. So, please don’t start lectures with those dismal learning outcomes, but just look at how Bond movies grab the attention and focus of their audience. Or just look at the Ascent of Man.

However, we can be sure of one thing, the current University system can’t monetise itself. The whole structure is propped up by state spending and huge loan books.

I had thought I ‘got’ Open as in terms of OER, Creative commons and the like, but clearly I am missing something (and in truth I have suspected I am missing something, for quite a while). This is from Stephen Downes:

Your new word for the day is ‘copyfraud’. Here’s the definition from Wikipedia: “Copyfraud refers to false copyright claims by individuals or institutions with respect to content that is in the public domain. Such claims are wrongful because material that is not copyrighted is free for all to use, modify and reproduce.” In the current case, copyfraud also applies to materials that are license CC-by. As Peter Murray-Rust writes in the GOAL mailing list, “Springer took all the images published in its journals and stamped COPYRIGHT SPRINGER over all of them and offered them for sale at 60 USD. This included all my publications in BioMedCentral, a CC-BY Open Access journal…” In another post he notes that Oxford University Press is “charging large prices for re-use of CC-BY articles (e.g. 400 USD for use in an academic course pack for 100 students.”

Clearly my idea of what CC-BY meant is wrong. There are other issues however I don’t understand. You use material from the web marked CC-BY-SA in a lecture or video that is hosted on a private site (say a university VLE). How does this work?

Students flocked to his evening classes

by reestheskin on 14/02/2016

Marvin Minsky has died. There is a wonderful description in Steven Levy’s ‘Hackers’ about Minsky and The Tech Model Railway Club and Midnight Computing Wiring Society at MIT. It is inconceivable now to imagine a university tolerating such a state of affairs: the state of affairs that was key to the development of the modern world. Rebellion and discovery are often of a piece.

The people in charge of the lab, particularly Marvin Minsky, were very understanding about these things. Marvin, as the hackers called him (they invariably called each other by last name, knew that the hacker ethic was what kept the lab productive, and he was not going to tamper with one of the crucial components of hackers. On the other hand, there was Stu Nelson, constantly at odds with the rules, a hot potato who got hotter when he was eventually caught red-handed at phone hacking. Something have to be done. So Minsky called up his good friend Ed Friedkin, and told him he had this problem with an incredibly brilliant 19 year old who had a penchant for getting into sophisticated mischief. Could Fredkin hire him?

Stewart Brand’s description nails it:

I think that hackers — dedicated, innovative, irreverent computer programmers — other most interesting and effective body of intellectuals since the framers of the US Constitution….. No other group that I know of has set out to liberate a technology and succeeded. They not only did so against the active disinterest of corporate America, their success forced corporate America to adopt their style in the end. The quietest of all the ‘60s subcultures has emerged as the most innovative and powerful. 

Professor Nicholas Negroponte, co-founder and chairman emeritus of the Media Lab, says:

“Marvin talked in riddles that made perfect sense, were always profound and often so funny that you would find yourself laughing days later.”

And from the Economist’s obituary.

He also, almost by the way, did other things, such as inventing a confocal scanning microscope and robotic “seeing hands” for surgery. His own intelligence continually leapt between postulations and speculations, all delivered with an endearing smile: what a thinking machine would have to notice when it drove down the highway, whether robots could be made tiny enough to beat up aphids or dexterous enough to put a pillow in a pillowcase, what would happen if you wrote “Eine Kleine Nachtmusik” to a different rhythm. Students flocked to his evening classes, never quite knowing what mental challenge he would toss out next.

Publishing: compare and contrast

by reestheskin on 09/02/2016

Comments are disabled

Remember those compare and contrast questions (UC versus Crohns; DLE versus LP etc.). Well, look at these two quotes from articles in the same edition of  Nature.

The first from the tsunami of papers showing that ‘Something in rotten in the state of Denmark Science’ — essentially that the Mertonian norms for science have been well and truly trampled over.

Journals charge authors to correct others’ mistakes. For one article that we believed contained an invalidating error, our options were to post a comment in an online commenting system or pay a ‘discounted’ submission fee of US$1,716. With another journal from the same publisher, the fee was £1,470 (US$2,100) to publish a letter. Letters from the journal advised that “we are unable to take editorial considerations into account when assessing waiver requests, only the author’s documented ability to pay”. 

The second is about attempts to piggyback on the arXiv server. An earlier article and blog post from Timothy Gowers says more.

Discrete Analysis’[the journal] costs are only $10 per submitted paper, says Gowers; money required to make use of Scholastica, software that was developed at the University of Chicago in Illinois for managing peer review and for setting up journal websites. (The journal also relies on the continued existence of arXiv, whose running costs amount to less than $10 per paper). A grant from the University of Cambridge will cover the cost of the first 500 or so submissions, after which Gower hopes to find additional funding or ask researchers for a submission fee.

Well done the Universities of Cambridge and Cornell (arXiv). For science, the way forward is clear. But for much clinical medicine, including much of my own field, we need to break down the barriers between publication and posting online information that others may find useful. This cannot happen until the financial costs approximate to zero.

Publishing and a race to the bottom

There is an article in the FT highlighting the woes of Pearson, and the wisdom of selling the FT and the Economist. My interest is in the vigour and prospects for textbooks in a digital age, a topic that feature highly in the article. As some other commentators state, maybe we are going to see a race to the bottom with margins being slashed as ‘free’ but poor quality becomes the norm. Just like what has happened to most quality journalism. There are of course alternatives, if only the universities would step up.

“Did you know that this is the 30th anniversary of the very first fully online course?” –

Via Tony Bates.

 

“A very simple explanation is: In corporate, they have money”

Many big companies also pay for corporate learning services to administer and track internal programs like sexual harassment training. That has already led some academic-focused start-ups to rethink their audiences.

A very simple explanation is: In corporate, they have money,” said Josh Coates, the chief executive of Instructure, an ed tech company that has broadened its strategy.

In 2011, Instructure began marketing a learning management system, called Canvas, to universities and school districts. Last year, the company expanded its business into employee-training platforms for corporations. Mr. Coates said he expected that Instructure would eventually derive much of its revenue from companies, which pay higher fees than schools.

“If they can make an employee 2 percent better by paying $50 for corporate training, they are going to do that in a heartbeat,” Mr. Coates said. “A school can’t do that kind of calculation. It’s not an obvious return on investment.”
