Equal input, unequal outcomes
A companion to Chapter 6 of the book, The Value of Personalised Learning. The same ideas in several forms: film, conversation, 2 infographics, a mind map and 6 activities. Start with whichever suits you.
Chapter 6 in two minutes
Uniform delivery creates cognitive friction. When the method does not fit, learners spend effort working around how the material is presented instead of engaging with the material itself. Chapter 6 argues that alignment matters because attention and working memory are limited, and that effort is better spent on understanding.
The chapter sets out three returns. Learners gain engagement, retention and confidence that carries into real work. Trainers prepare more sharply and improvise less. Organisations see faster time to competence, fewer resit cycles and a return on training spend they can measure. One evaluation it cites found nearly twice the learning gain under adaptive delivery.
It is also a question of fairness. Giving everyone the same session is equality of input, not equality of outcome. Making variation in explanation, activity and pace the default opens access for neurodiverse and culturally varied learners, while the objectives stay the same for everyone.
Equality of input is not equality of outcome.
