today I am not talking about …
• intelligent internet interfaces• visualisation and sampling• small device – large display interactions• fun and games, virtual crackers,
artistic performance, slow time• physicality and product design• creativity and Bad Ideas• modelling dream, regret,
the emergence of self
… or even lots of lights

first MOOC?
Sept/ 2011, Sebastian Thrun’s Intro. to Artificial Intelligence160,000 signups
… but for what?
TAs doing assessment … but issues of accreditation
filmed in his basement …
… and then …
benefits
brand awareness (overseas student recruitment)
development consultancy (platform providers)
democratisation of education (… but who pays?)
sustainable?
use?
‘drop out’ often 90-99%but does that matter?success as accomplishing own
goalsN.B. FutureLearn and P2PU a lot better
democratisation?most students graduates and
western
life before the MOOC?
… before the MOOC
let’s have a go
online HCI course
ran early 2013to gain experience
with ‘MOOCs’and reusable materials
now hosted at OER siteinteraction-design.org
Human–ComputerInteraction
low cost productiontalk-over slides + head & shoulders video + additional resources
development ~ 3–4 months
~ 25 hours video
academic sharing quality
reuse in flip / blended learning
Autumn 2014 coursemix of UG3 & MScportion of course (4 weeks)mixing video with face-to-face
Spring 2015 coursemasters students onlysingle session
different mixes
basics + integrationpreparatory videos on ‘basics’ followed by integrative lecture (chalk & talk!)
2 fully flippedvideos followed by discoursive F2Fvideos followed by group discussions
2 part & partall material on video, some also taught in class N.B. noticable attendance fall-off when told in advance!
70 students

micro-analytics … individual course resource student
analytics – who read/viewed whattypically about 1/3 watch everything, 1/3 some, 1/3 none at all!
used stats to ‘encourage’ students in class
N.B. did not look at individual student analytics
students did not seemphased by this level of analytics
analytics – how much
journal paper PDFrecommended reading
most students just read beginning
in class explained structure of paper
every one loves a MOOC(well they did in 2013!)
but what does it cost?
Effort: Glasgow University FutureLearn
Two courses:Right vs Might
360 hours academic + 800 hrs learning technologist (development only)2.5 hours of video + supporting resources656 participants (first run)
Genomics 2236 hours academic (development only)6 hours video + supporting resources747 participants (first run)
Source: Building and Executing MOOCs: A practical review of Glasgow’s first two MOOCsJ. Kerr, S. Houston, L. Marks, A. Richford (2015)
Comparison
• MOOCs– 400 hours development time per hour video– 700 participants per run (time amortised)– £29 statement of participation (~15% takeup)
• Traditional Classroom– 2–4 hours preparation per hour lecture– 50-200 students per lecture (time repeated)– £9000 fees (for ~ 200-300 hours lectures)
Bottom line
MOOCs vs classroom
10 times as many students
100 times the effort
1/30 payment / student–hour
other estimates?
$39K to $325K per MOOC$74-$272 per completer

Udacity ~ $200K per courseEdX ~ $250K design + $50K per run

High quality video ~ $4K per hour (1)

massive
does size matter?
what is scale?
Seminar – 10s of students
Lecture – 100s of students
MOOC – 10,000s of students
… but …
1 0 0 million new tertiary students
every year
face to face learning …
growth … total tertiary students
2010 – 180 million
2025 – 260 million
40%
face to facelearning
is @ scale

reuse offline?
reuse and online ’content’
online ‘content delivery’:senior mgt pressure since 1990sprincipally for cost saving!
reuse:LOs, SCORM, Tin-Can APIwe all know it’s good in HE use still limited

small is beautiful
video length:often suggested 4 mins or even 2 minssmaller resources improve engagement (Ferriday)
we saw 10 mins OK but 20 mins too long
=> need better ways to create, edit and manage smaller videos
both for in-class and flipped use
small things matter
already added end as well as start times in Player
maybe need better fade-in – fade-out for audio
sharing portions not just whole videos
narrative matters
all digital?
semantic textbook – data meets text
book
MCQsvideos
slides
learning analytics
big data for education
MOOC scale
lots of studentsfollowing the same course
large volumes of homogeneous data
heterogeneitycourses andinstitutions
individualitylearning styles
patterns of viewing
cross-institutionalissues
ownership and privacy
abstracting heterogeneity ?individual traces classes of behaviour
big data analysis pedagogic feedback
reality more complex
… and very messy
lots of work still to do!

in summary
MOOCs (potential) benefits… but costly … sustainability?
face to face is also massive!(re)use MOOC-like material in class?
analytics of heterogeneity
