Peter Norvig: Online Education - One Year Later

Peter Norvig uses this 14 November 2012 talk at Stanford University (~34 minute talk; ~22 minutes of discussion - questions just about audible) to reflect candidly on what he learned from making and running the mass online AI course with Sebastian Thrun last year.

The screen-shot below has Norvig's concluding slide, which he uses to support the idea that in the future online learning will i) feel to learners like 1:1 instruction, ii) be organised with cohorts of 100,000, and iii) use analysis of the "big data" flowing from masses of peer:peer interactions to shape formative feedback to individual learners and/or determine how a learner is "routed" through their studies.

For more on how this might work, see Norvig's responses - optimistically to the question that is asked at 39:10, and more cautiously to the question asked at 51:40. See also his answer to the question asked at 53:10 for an interesting insight into how Google itself has been testing the impact of its own online search course (which, like the AI course, attracted over 150,000 learners) on the actual search behaviours of users.

As an aside, it is worth considering Norvig's comments on Carnegie Mellon University's efforts to create a mathematics tutoring system alongside observations made by Dylan Wiliam in Scaling up: Achieving a breakthrough in adult learning with technology a report I wrote earlier this year with Adrian Perry, Clive Shepherd and Dick Moore. Here is an excerpt:

A particular barrier to successfully creating software that helps learners develop their conceptual understanding is the great difficulty in building a solid proficiency model or map of a knowledge domain. For example, a well-funded team of expert researchers at Carnegie Mellon University developed an effective tutoring system (now called the Cognitive Tutor56) for a relatively small proportion of the US equivalent of the Year 10 algebra curriculum. Dylan Wiliam, Emeritus Professor of Educational Assessment at the Institute of Education, University of London, explains: “The Cognitive Tutor has been very well researched and it’s very effective. It’s probably better than 90% of teachers that are teaching this part of the curriculum. But one of the reasons it is so effective is that its focus is on such a very constrained domain. And it still took the Carnegie Mellon team 20 years to work out what are the knowledge structures that are involved in this domain.” In short, whilst the computer science behind the tutoring system is robust and getting even more so, the proficiency models of learners’ cognition are neither well developed nor easy to create.

Stolpersteine - joining up the personal and the professional in a 20 minute talk about learning technology

Sculptor Gunter Demnig and his co-worker embedding three Stolpersteine (stumbling blocks) into the cobbles outside 52 Oderstrasse, in Neukölln, Berlin, on 29 November 2012.

Small addition to final paragraph made on 10 May 2013

Today I gave a talk at a conference in Berlin called Online Educa, in which I tried to meld the personal and the professional into one piece. So far as I could tell from the audience reaction this worked: but partially. (Link to the presentation I used [45 page 3 MB PDF, includes the script for the talk]; link to a somewhat "heavy breathing" video recording of the talk; link to other videos of talks at the conference on the Online Educa web site).

Below is a series of pictures I took yesterday (on 29 November) of sculptor Gunter Demnig and his co-worker embedding three Stolpersteine (stumbling blocks) into the cobbles outside 52 Oderstrasse, in Neukölln, Berlin. The Stolpersteine commemorate Selma Lewin, Martha Meth and Max Meth, and the pictures show descendents of the family at the informal ceremony that was held, and childred from a local school who had become involved in  researching Selma, Martha and Max.  Eight further batches of Stolpersteine - 18 in total - were embedded by Demnig on the same day in Neukölln. Between Tuesday and Friday of this week a total of  115 Stolpersteine were laid outside 36 houses all over Berlin. [I am in the process of arranging Stolpersteine to be laid outside the block where my grandparents and great grandmother last lived in Berlin, before they were taken to Terezin in Autumn 1942.] You may also be interested in this May 2013 piece by Andreas Kluth, the Economist's Berlin Bureau Chief.

From the horses' mouths - Janet Finch and Mark Thorley speaking to research librarians about developments in UK Open Access

Last week I picked up on Stephen Curry's 15 November talk to the 2012 Research Librarians UK Conference. Below I've embedded the recordings of Janet Finch and Mark Thorley's talks a the same event. You may also be interested in Curry's own reflections on the event.

[Updated 25/11/2012]

I enjoyed this candid witty almost samizdat^* 15 November talk by Stephen Curry at the 2012 Research Libraries UK conference. I think plenty of readers would do likewise, as much as anything else because Curry's perspectives are those of a highly visible life scientist who "came to Open Access late", mainly as a reaction to the (subsequently failed) US Research Works Act [slide 3]. Curry is mercifully unzealous, and also clear about how complicated OA issues actually are.

To my mind he gets the balance right between Gold and Green; and he understands the reasons for the differences between disciplines in their views about OA. He also talks persuasively but realistically about impact factor and the need for alternative ways of judging the quality of an article than by the prestige of the journal in which it appears. Curry's "Why we are not there yet?" points [on slide 11], and list of "Residual challenges" (slide 14) are spot-on, not least his calls for a unification of "the broad church of OA", and for openness on the profits and taxes of the publishers.

Climate change - seven reasons why things are looking even grimmer than after the 2009 IPCC

2007 flooding of my aunt and uncle's street in Mercedes, Uruguay

This week's New Scientist has six page piece about Global Warming by Michael Le Page. You need a subscription to access it on line. This is the kind of article that New Scientist should make freely available, on a public service basis. Here are the article's seven headlines, preceded by its summary paragraph.

Five years ago, the last report of the Intergovernmental Panel on Climate Change painted a gloomy picture of our planet's future. As climate scientists gather evidence for the next report, due in 2014, Michael Le Page gives seven reasons why things are looking even grimmer.

1. The Arctic is warming faster than predicted
2. Extreme weather is getting more extreme
3. Food production is taking a hit
4. Sea levels will rise faster than expected
5. Greenhouse gas levels could keep rising even if our emissions stop
6. We're emitting more than ever
7. Heat stress means big trouble

Decoding Learning - a report that gets to the heart of the challenge of enhancing learning with technology

NESTA's Decoding Learning [90 pages, 4.4 MB PDF], published today, was written under contract by Rose Luckin, Brett Bligh, Andrew Manches, Shaaron Ainsworth, Charles Crook and Richard Noss from the Learning Sciences Research Institute at Nottingham University and from IOE/Birkbeck's London Knowledge Lab. 

The report has caught the attention of the media, with much of the coverage having a strong "money wasted by stupid people and organisations" flavour. (BBC - Costly hi-tech kit lies unused in schools, says study; Telegraph - Schools 'wasting £450m a year' on useless gadgets.)

But this is an important report, because it gets right to the heart of the challenge of enhancing learning with technology in schools (and elsewhere), whilst retaining an underlying (and evidence-based) optimism.

To encourage you to read the report in full, and to give you its overall flavour, here is its concluding section in full.

We looked for proof, potential and promise in digital education.

We found proof by putting learning first. We have shown how different technologies can improve learning by augmenting and connecting proven learning activities. This approach gives us a new framework for evaluating future innovations in education.

The numerous examples of good practice identified in this report show that there is also a great deal that can be done with existing technology. It is clear that there is no single technology that is ‘best’ for learning. We have identified technology being used effectively to support a variety of learning activities and learners across a wide range of subjects and learning environments. Rather, different technologies can be used to support different forms of learning, either individually or in conjunction with others.

There is a growing body of invaluable evidence that demonstrates how technology can be used effectively to support learning. However, if that evidence is going to be useful in practice it needs to address the contexts within which the technology is used; and it needs to be presented in ways that are accessible to industry, teachers and learners.

We found clear potential to make better use of technologies that are widely available and that many schools have already purchased. But this potential will only be realised through innovative teaching practice. Teachers may require additional training that enables them to use technologies in new ways.

There is enormous potential for further innovation in digital education. Success will come from commercial developers, researchers, teachers and learners working together to develop, test and spread imaginative new technologies.

We also found many areas of promise; that is, areas where technology is currently undervalued and underused. We found relatively little technological innovation in some of the more effective learning themes we considered in Chapter 2. For example, the market is saturated with drill and practice games (particularly for maths) to support Learning through Practising despite being regarded as one of the less powerful learning themes. Meanwhile, there has been relatively little technological innovation aimed at supporting Learning through Assessment – which can be a powerful aid to teaching and learning.

Over recent decades, many efforts to realise the potential of digital technology in education have made two key errors. Collectively, they have put the technology above teaching and excitement above evidence. This means they have spent more time, effort and money looking to find the digital silver bullet that will transform learning than they have into evolving teaching practice to make the most of technology. If we are to make progress we need to clarify the nature of the goal we want to satisfy through future innovation. Much existing teaching practice may well not benefit greatly from new technologies. As we continue to develop our understanding of technology’s proof, potential and promise, we have an unprecedented opportunity to improve learning experiences in the classroom and beyond.

Inventing the future of learning

It is amazing how Barbara Flynn's familiar-sounding narration adds credibility to a documentary such as this one.

The video was launched at the The Royal Society on 6 November at the closing event of the TEL Research Programme.  It aims to highlight - for a lay(ish) audience - the results of 8 four-year ESRC/EPSRC funded Technology Enhanced Learning projects, and to emphasise the scope that now exists for TEL to "take off", ubiquitously and at scale, and in a designed rather than random way. I think it largely succeeds in this, though if the documentary has a weakness it is it's lack of focus on the big impact that TEL is already having. Public figures featured - alongside teachers, learners, and researchers, include:

• Tim O'Shea, Principal of Edinburgh University;
• Charles Clarke and Jim Knight, former Labour Secretaries of State for Education;
• Michael Gove, the current Coalition Government's Secretary of State for Education;
• Eban Upton, the designer of the Rasberry Pi;
• David Puttnam;
• Eric Schmidt, Chairman of Google;
• Mitchel Resnick, from MIT Media Lab.
