- George Santayana
- Preaching to the choir Actionable intelligence on learning. Importance of acting. Catnip for senior managers
- It’s a developed visualisation: draw it as a cycle. Also underpinned by educational theories. Cycles common – technology hype cycle; been here before with learning objects; carbon cycle
- Not doing Learning Styles Broad parallel: Concrete experience = learners; reflective observation = (generate) data; abstract conceptualisation = metrics, active experimentation = intervention Also for individual: LA can make reflective obs/abstract conceptualisation easier
- Single loop, double loop – thermostat – really important here: optimise for the right goals This cycle idea – reflection, professional practice – taken up in lots of professional fields, from architects and anthropologists to zoologists, health and social care.
- LA facilitates the conversation at level of actions (info on students action and feedback) , and conceptions (richer (data-informed) redescriptions) – less easy at this level (optimise rightly!)
- LA working to enable conversations at multiple levels – concrete, abstraction – between multiple teachers and learners
- Engineering Control theory, Closed loop control system – feedback from output to input crucial. Example of thermostat. Open loop control system – cooker with pan on top. Heat provided only depends on settings, not on temp of output. Human in -> feedback if it boils over. Open loop – quick, simple, cheap. But need good model of what’s going on. Breaks if unexpected happens Closed loop – slower, harder. But robust so long as the inputs your adjusting do affect the output in the way you think it does. Much in control theory – if delay in feedback adjustment, can get self-exciting oscillation (overcompensation), use hysteresis or speed up.
- Speed, scale, quality of response Get it to the learners and teachers
