Daphne Koller: The University has flipped and The OU should have been there first

Visible to anyone in the world

Daphne Koller is a professor of Computer Science at Stanford University and a Third generation PhD. In this insightful talk we learn how e-learning is changing learning opportunities globally. Scale is at the heart of it.

A Machine Learning Class at Stanford with an undergraduate enrolment of some 400 when put online is followed by 100,000. And the lessons from scale led to the creation of Coursera where anyone can take the world’s top classes for free - delivered by the best instructors from the best universities.

  • Personalised curriculum
  • A coherent concept in 8 – 10 minutes
  • Students can traverse the content in different ways background, skills or interest.
  • Support or enrichment.

Practising with the material is important.

Video is interrupted to pose questions. Students are expected to engage.

  • Multiple choice
  • Short answer questions
  • Grade math and models

To be told when you are right or wrong is essential to student learning.

How do you grade 100,000 students?

Peer grading is a surprisingly successful strategy (Sadler & Good, 2006) .

  • Teacher and student grades extraordinarily similar, even self-grades.
  • And the student learns from the experience.

And learning is socialised

  • Around each of our courses a community of students has formed.
  • Some meet online, others locally.
  • Students respond to each other’s queries.

‘The median question to response time was 22 minutes because somewhere around the globe there was someone awake’. (Koller, 2012)

From 0:14:11

‘There are some tremendous opportunities to be had from this kind of framework’.

‘First it has the potential of giving us a completely unprecedented look into understanding human learning because the data that we can collect here is unique. You can collect every click, every homework submission and every form post from tens of thousands of students so you can turn the study if human learning from the hypothesis driven mode to the data driven on transformation that for example has revolutionized biology.

0:14:40

You can use the data to understand fundamental questions like what good learning strategies are versus ones that are not and in the context of particular courses you can ask questions like what are some of the misconceptions that are more common and how can we help fix that. 2000 students give the same wrong answer ... produce a targeted error message to give personalized feedback.

Fig. 3. Benjamin Bloom (1984) , 2 Sigma problem.

Lecture, mastery based approach, taught one on one with a tutor. individual gives you 2 sigma improvement 50/50 Individual 98% above average But cannot afford to provide every student with an individual tutor. Mastery will grade multiple times and show you the same video over and over without getting bored.

How can we push towards the 2 Sigma curve.

‘The mind is not a vessel that needs filling, but wood that needs igniting. From Ian Kidd's translation of Essays’. Plutarch

0:18:50 More time required igniting their creativity, their imagination and their problem solving skills by talking with them. We do that by active learning in the classroom.

Performance improves by every metric:

  • attendance
  • engagement
  • standardized tests

It would do three things:

  • Establish education as an absolute fundamental human right.
  • Enable lifelong learning
  • A wave of innovation

Ditch the E and the M - it's learning

Visible to anyone in the world
Edited by Jonathan Vernon, Friday, 28 Sep 2012, 14:02

It's just learning ... the greatest thinkers on educational are largelly pre-digital: Dewey, Vygotsky, Piaget, Kolb, Bloom, Briggs, Engeström, Gagnéet al.

E and M learning are advances on the Guttenberg Press or Power Point, but they are technologies all the same.

Web-Based Training (Part One)

Web-Based Training (WBT) (2000)

Margaret Driscoll

I bought this book in 2001. Nearly a decade on I am delighted how apt it remains, even if the term may now have been superseded by e-learning - while cyberlearning had currency for a few years too and before this we had 'interactive learning'.

Even a decade on I recommend the book.

Training and learning are in different camps, one supposing a component of applied engagement (health and safety, fixing photocopiers, burying uranium trioxide, driving a delivery van, making cars, selling phones, employee induction) while the other is essentially cognitive (though with its physicality in this kind of prestidigitation).

Yet we made ‘training programmes’ on things like cognitive behavioural therapy. Corporate and government clients had the money to do these things.

Driscoll’s definition of WBT is somewhat longer than Weller’s definition (2007) of e-learning (electronically enhanced learning with a large component of engagement on the Internet). A bit ‘wishy-washy’ my exacting Geography A’ Level teacher would have said.

Hardly a clear definition if it has a let out clause. But when was anything clear about what e-learning is or is not, or should be? The term remains a pig in a poke; its most redeeming factor being that it is a word, not a sentence, and fits that cluster of words that includes e-mail.

Web-based training Driscoll (2000) says should be:

  • Interactive
  • Non-linear
  • Easy to use graphic interface
  • Structured lessons
  • Effective use of multimedia
  • Attention to educational details
  • Attention to technical details
  • Learner control

I like that. I can apply it in 2011. I did.

I was reading ‘Web-Based Training’ (and using the accompanying CD-rom) in 2001 and then active in the development of learning, or knowledge distribution and communication websites for the NHS, FT Knowledge ... and best of all, Ragdoll, the home of Pob, Rosie and Jim, Teletubbies and the addictive pleasures of ‘The Night Garden.’

We may call ourselves students, mature students even, or simply post-graduates, but would we call ourselves ‘Adult Learners.’

It’s never a way I would have defined my clients, or rather their audiences/colleagues, when developing learning materials for them in the 1980s and 1990s. Too often they were defined as ‘stakeholders,’ just as well I saw them as people and wrote scripts per-the-script, as if for only one person.

That worked, producing for an umbrella term does not.

Adult Learning doesn’t conjure up innovative e-learning, perhaps because of the connotations Adult Learning has inelation to the catalogue of F.E. courses then comes through the door every July or August.

This definition of an ‘adult learner’ would apply to everyone doing an OU course surely?

The special characteristics of adult learners Driscoll (2000:14)

  • Have real-life experience
  • Prefer problem-centred learning
  • Are continuous learners
  • Have varied learning styles
  • Have responsibilities beyond the training situation
  • Expect learning to be meaningful
  • Prefer to manage their own learning

With some of these definitions baring more weight than others, don’t you think?
