What is cognitive apprenticeship?

Cognitive apprenticeship is a model of instruction in which teachers make thinking visible: they model expert reasoning aloud, coach students as they attempt the work, scaffold the parts students cannot yet manage, and fade support as competence grows. Allan Collins, John Seely Brown and Ann Holum introduced the model to a wide audience in 1991.

Who developed the cognitive apprenticeship model?

Allan Collins, John Seely Brown and Susan Newman first described the model in a 1989 research chapter. The 1991 American Educator essay by Collins, Brown and Ann Holum, restored on this page, is the version most educators cite and assign.

What are the four dimensions of a cognitive apprenticeship learning environment?

Content (domain knowledge, heuristic strategies, control strategies, learning strategies), method (modeling, coaching, scaffolding, articulation, reflection, exploration), sequencing (increasing complexity, increasing diversity, global before local skills), and sociology (situated learning, community of practice, intrinsic motivation, cooperation).

How is cognitive apprenticeship different from traditional apprenticeship?

Traditional apprenticeship teaches physical work that is naturally visible, in the place where the work is used. Cognitive apprenticeship adapts the same arc to thinking, which is invisible: reasoning must be deliberately externalized, school tasks must be situated in meaningful contexts, and practice must be varied so skills transfer beyond a single setting.

What do modeling, coaching, scaffolding and fading mean?

Modeling: the expert performs the task and voices the reasoning while the learner observes. Coaching: the learner performs while the expert watches and guides. Scaffolding: the expert supports only the parts of the task still beyond the learner. Fading: support is progressively withdrawn until the learner works alone.

Overschooled but Undereducated: The Book

Page first published 2009 by the 21st Century Learning Initiative; the book appeared from Continuum in November 2009. Restored 2026.

Overschooled but Undereducated, by John Abbott with Heather MacTaggart, argues that by misunderstanding teenagers' instinctive need to do things for themselves, formal education has come to work against the natural grain of the adolescent brain, trivializing the very young people it claims to support. The Initiative regarded it as the most complete statement of its case.

What the original page said

This address was the book's home page in the Initiative's publications section, and its core text is worth preserving closely. The book, the page explained, synthesizes an array of research from both the physical and social sciences and shows how those insights contribute to a better understanding of human learning, especially as it relates to adolescence. By misunderstanding teenagers' instinctive need to do things for themselves, society risks creating a system of schooling that so goes against the natural grain of the adolescent brain that formal education ends up unintentionally trivializing the very young people it claims to be supporting. And by failing to keep up with research in the biological and social sciences, current educational systems continue to treat adolescence as a problem rather than an opportunity.

The page was equally clear about the book's ambition. This is a book about the need for transformational change in education, conceived through a series of international conferences and considering the education systems of Scotland, Wales, Ireland, Canada, the United States, Australia, and New Zealand. Its intention, the Initiative wrote, was to shake education out of its two centuries old inertia. The page closed with the sentence Abbott used as a moral summary of the whole project: in the saga of the ages, if a generation fails, the fault lies squarely with the previous generation for not equipping them well enough for the changes ahead; and the most immoral thing a person can ever say is, this will last out my time.

Publication history

The page recorded the book's route to print. The Initiative published a pre production edition in June 2008 under the working subtitle Society's Failure to Understand Adolescence. In December 2008 Continuum Books agreed to publish, and the trade edition appeared in November 2009 under the full title Overschooled but Undereducated: How the Crisis in Education Is Jeopardizing Our Adolescents, with a paperback following in 2010, which is why the book is variously dated 2009 and 2010. The original page credited both authors, Heather MacTaggart, founder of the Canadian organization Classroom Connections, and John Abbott, and offered the introduction as a download along with a page of reader responses and selected reviews.

With its publication, the Initiative wrote, it finally had in compact form the most complete, persuasive, and concise argument for the overhaul of current systems of education, a catalyst in print for the reassessment of the outdated thinking that governs educational policy and attitudes toward learning and schooling in the West.

The argument of the book

The book gathers the threads the Initiative had been assembling since the 1990s. From evolutionary biology and the brain sciences it takes the claim that adolescence is an adaptation, not an affliction: a stage built for risk, exploration, and the assumption of real responsibility, calibrated for a world in which the young learned by working alongside adults. From history it takes the record of apprenticeship, the arrangement that once met that adaptation on its own terms, and whose cognitive logic is set out in the archive's reference on cognitive apprenticeship. From the comparative study of school systems it takes the observation that the Western model concentrates its resources on older students at exactly the point when young people should be growing away from institutional dependence.

The title carries the thesis. Adolescents are overschooled: supervised, timetabled, and examined more intensively than any generation before them. They are simultaneously undereducated: denied the consequential work, graduated independence, and adult contact through which the species actually finishes its growing. The crisis in education, on this account, is not chiefly a crisis of standards or funding but a design mismatch between an institution and a life stage, and the remedy is structural: schooling redesigned so that dependence on teacher and school decreases with age, a principle the Initiative worked out in practical detail in its 2010 briefing Schools in the Future.

Where the book sits in the Initiative's work

Abbott described the book as the best summary of everything the Initiative had learned, and the archive treats it as the keystone. The 99 Theses compress its argument into a numbered manifesto; the briefings apply it to live policy questions; and Abbott's own restored profile traces how a grammar school master and comprehensive school head came to write it. The original page sat in the publications sequence next to a page of selected reviews, and the book's reception divided along predictable lines: enthusiasm from those persuaded that the biology of adolescence belongs at the centre of school design, resistance from those who read it as another assault on academic standards. The Initiative's answer to that resistance was always the same: the argument stands on the research, and the research had not been answered.
