follows the T model
what we teach

grounding
why T ?
• texture• more engaging!
• grounding• more rigorous
• mastery• more motivating
division
what does it mean?
multiplication
3 x 4 = 12
4 x 3 = 12
division
12 / 3 = ?
? ? ?
?
12 / 3 = ?
building a house
• length of roof = 5 metres• beams in 2 metre sections• can cut and join• how many sections do I need?
5m2m

transporting the beams
• length of trailer = 5 metres• beams in 2 metre sections• how many sections can I carry
5m2m2
lifting the beam
• length of roof = 5 metres• each 2m section weighs 1 tonne• can cut and join• what does the full beam weigh?
5m2m
21/2
1 tonne
division?
• number of beams to buy?5 / 2 3
• number of beams in trailer?5 / 2 2
• weight of beams?5 / 2 21/2
Reflection
where we are now
using IT in education
Reflection at 2002
• IT Master Plan …
… lots of computers
• what to do with them?
golden rule of design
understand your materials
computerscontentpupilsyourself
physical things
• directness of effect– push and it moves
• locality of effect– here and now
• visibility of state– small number of relevant parameters
what’s special about computers?
• complexity of effect– computation
• non locality of effect– in space – networks– in time – memory
• hidden state– large number of invisible variables
driving lesson
what happened
• removed external judgement– I didn’t know intention
• allowed personal feedback– she did know
• enabled “play” and experiment– not goal directed

draw a triangle?
Montessori
• self correcting materials• instant feedback• no judgement

computers
• rapid feedback– before bad habits form– e.g. spelling checkers
… but not correctors!
• low judgement …
computer personality
• work at Dundee– questionnaires and interviews– personal questions (medical)
• electronic versions– simple questionnaires – keyword based (like Elisa)– the more human-like the better– but better than real human
Changing Face of Technology
what has happened since 1996
changes in IT
Changing Face of Technology?
• in 1996– still mainly the locally networked PC
• in 2002– computing is the Internet– mobile, wearable,
internet appliances, …
• in 2008?
the Net
• WWW– wonderful resource … but …– affordances and authority?
the Net
• WWW– resource … but … affordances, authority?
• mobile devices– the global everywhere … – and local information
the Net
• WWW– resource … but … affordances, authority?
• mobile devices– global everywhere … local information
• communication– global community – culture & values?– local community – through global net!
how many computers?
• in your classroom
IT MasterPlan – 1 for 2 pupils– 30% curriculum
how many computers?
• in your classroom
• in your home
TV, video, DVD,washing machine,air conditioning,microwave, …
how many computers?
• in your classroom
• in your home
• on your person
PDA, phone,car keys, smart cards,camera, walkman, …
Challenges Lying Ahead
what will happen
the long vision
Challenges Lying Ahead
• technology– has changed society– is changing society
• education– to accommodate change– to use change– to affect change
four ages of information
• Age of Proximity– control and information by physical
contact
four ages of information
• Age of Proximity• Age of Bureaucracy
– long-distance remote contact– physical messages– early cyberspace
four ages of information
• Age of Proximity• Age of Bureaucracy• Age of Money
– freemarket economies:– exchange of value– exchange of information
four ages of information
• Age of Proximity• Age of Bureaucracy• Age of Money• Age of Information
– electronic messages– information objects– challenges power structures– remolds economics
digression
a brief history of learning
a lightning tour through evolutionary time …
Genestimescale: 1000s of generations
individual learningtimescale: within a lifetime
depends on memory and imagination
parents and packstimescale: across generations
depends on co-experience and learning
gesture and languagetimescale: across generations
imagination and vicarious experience
playtimescale: within and across generations
imagination and virtual experience
last words …
• technology is changing• but people are the same
• understand technology• understand learning
