#UKEd #EduSky Intro to Rethinking Cognitive Load Theory. Despite Sweller explaining the Transient Info Effect to be primary (Fröyd's Toolbox Episode 56), I notice its significance is still missing. Merlin Donald's evolutionary theory would rectify this blind spot.

This looks juicy and will, I'm sure, offer the more nuanced, finely-observed side of cognitive science, beyond the merely behavioural instantiation (that is temptingly simple to understand and convert into evaluation checklists).

Here's our a very condensed version! Situation: whole school alignment - gotta catch those lethal mutations! Theory: Rosenshine's Principles (+ others) Actions: Consistent use of The WalkThrus and codification Results: Significant improvement in consistency from Pre-school-Y6

The current use of the term "to land" is a poor way of capturing communication, as it stems from the notion that it's a one-way stream. One doesn't just lob a sentence or two 'over there' and hope it 'lands'. That is performance, not communication.

#EduSky #UKEd According to CLT, the diagram causes the Redundancy Effect because it doesn't add info than is in the text. But, as Larkin & Simon's 1987 paper found a diagram can be informationally equivalent but computationally asymmetric (easier to understand than the text). Update needed?

#UKEd #EduSky Coaching develops — as in team coaching. Business was there more than a decade ago (see J Britton's From One to Many: Best Practices for Team & Group Coaching). Make it less personal but more personally beneficial as common problems & new solutions emerge from the team.

#UKEd #EduSky According to CLT's redundancy effect ("multiple sources of info can be understood separately"), the RHS diagram is not needed; causes overload in fact. But some learners need both. Larkin & Simon (1987) concluded that diagrams often are more computationally efficient. Use both.

#UKEd #EduSky Coaches help identify real classroom challenges by offering an additional perspective: observing where students are struggling, offering practical tools for visits, data and videos to build insight, test hunches and explore learning problems.

#EduSky #UKEd Given that Richard Mayer asserts that we learn best with a combination of words and images, it's essential that we consider of the quality of execution. And none better to remind us than Clark & Lyons (in their 500+ page ultimate research compendium).

#UKEd #EduSky I'd say this is THE blog of the year. When real replication comes in education, hubris often follows. So, of course, strive to be evidence-informed but, please, a little less confidence & pride when describing one's practice. Bravo to @C_Hendrick.
