Camtree, the Cambridge Teacher Research Exchange, is a project that sits within DEFI. It is creating a global platform for educators around the world who wish to reflect on their practice and conduct research on improving learning in their classrooms and institutions.

Our research exchange platform will enable them to share and publish their research and to learn with, from and on behalf of like-minded colleagues around the world. This in turn will contribute to a growing knowledge base of early-stage pedagogic innovations that can inform policy, practice and improve learning outcomes for all – especially the most vulnerable and disadvantaged.

A growing weight of evidence now demonstrates that a highly effective way of improving pupil outcomes in schools is for leaders to lead teachers in conducting informed, collaborative classroom research into the learning of their students.

Robinson et al.’s 2009 meta-study of 800 research projects found this approach leads to improvements of such scale that those students previously four fifths down the rank score order in the school population improve to the level of the former highest attaining students. And the former average and highest scoring students improve to the same degree. 

Through this collaborative, research-driven approach, teachers develop a much greater and a shared awareness of how their curriculum and teaching are affecting their pupils’ learning and exactly what needs to be done to improve it.

Camtree will be the world’s first platform that helps teachers and school leaders to improve learning in this way.

And by developing a growing global community of active classroom practitioner-researchers and leaders sharing their work, it will promote improved outcomes in classrooms world-wide.

What we do

Camtree operates in four ways to:

Curate, promote and publish high-quality, ‘close to practice’ practitioner research amongst a growing international community of Camtree practitioner-researchers

The Cambridge Teacher Research Exchange (Camtree) is a web-based platform that guides and publishes user-generated classroom research reports. Camtree will grow and support a community of research-active, high-quality, school-based classroom research leaders across the world who stimulate interest in classroom research in their schools, recruit and support contributors of such research amongst colleagues who also act as reviewers for classroom research reports of interest posted by teachers around the world.

Provide training and support for research-led improvement and leadership in schools, higher education and other formal/informal settings

Outstanding practitioners will be recognised as ‘Camtree-leads’, trained and licenced to provide Camtree services in their localities to teachers and institutions in how to carry out key forms of classroom research including internationally recognised Cambridge dialogic, collaborative classroom development and research approaches such as Oracy, Research Lesson Study and Teacher SEDA. The Camtree platform will itself provide e-learning, live and recorded webinars, blended courses and bespoke Camtree-lead-delivered consultancy, training and support to practitioners and schools. International partner organisations will be encouraged to participate and support this work.

Systematically review the Camtree database and publish research findings and reports

Creating the world’s largest and most current database of classroom research published by members, Camtree will provide commissioned analyses and advice from paying customers, as well as publishing regular insight reports from meta-analyses of Camtree studies. Customers will range from education publishers and ed-tech companies to schools, school systems, policymakers and decision-makers.

Host bespoke Camtree domain services to school systems and governments worldwide

Once established, major new customers – such as large school systems or government education departments – will be able to develop and operate their own Camtree domains with training and analysis – under license. There will be strict data-sharing protocols and permissions in place to enable comparisons between data held in different domains to be made for specific, agreed purposes.

Who we are

Dr Peter Dudley has a track record of success leading and innovating in school systems and national policy as well as researching and evaluating these changes. He has been president of the Singapore-based World Association of Lesson Studies for five years representing over 50 countries working closely with leaders in this field worldwide. As National Director of the last UK Labour government’s education National Strategies he created WhatWorksWell – a forerunner for Camtree that attracted huge national and international audiences and participation.

As a senior member of the National College for School Leadership’s Networked Learning Communities programme, he developed Research Lesson Study, a UK variant of Japanese lesson study, which is now used in over 12,000 schools across the UK, Europe and Asia. As Director of Education in the London Borough of Camden, he led the creation of the successful not-for-profit, schools company ‘Camden Learning’ which harnesses schools partnership-led professional knowledge creation and mobilisation as a core driver of change and improvement. He is senior member of Hughes Hall and education leadership lecturer at the Faculty of Education. Read More.

Dr Sara Hennessy is a Reader in Teacher Development and Pedagogical Innovation in the Faculty of Education at the University of Cambridge. She is a Research Director of the EdTech Hub, a multi-million pound 8-year FCDO-funded programme investigating the potential for using educational technology to raise outcomes for marginalised learners in low-income countries. She has been researching in the area of educational technology use in classrooms for more than three decades and is an Editor of the British Journal of Educational Technology. Outputs include open, multimedia professional learning resources (e.g.

Sara is also co-founder and co-leader of the interdisciplinary Cambridge Educational Dialogue Research (CEDiR) group. She collaborates with teachers as researchers, bridging research and practice, and co-leads the Teacher-SEDA programme. The team has developed resources supporting teacher inquiry into dialogic practices that have been used by over 300 teachers in at least 8 countries. Read More.
