The Child Development and Learning (CDL) group develops and drives cutting-edge research in: children’s language, literacy and mathematics learning with a focus on both typical and atypical development; the quality of provision and curriculum; parents’ engagement with their children and the professional development of staff.

Our focus is on ways in which learning environments and within-child factors shape cognitive, language, social, emotional and physical development from birth-to-twelve. We are interested in gathering descriptive, correlational and causal evidence. We apply state-of-the-art quantitative, qualitative, and mixed methods research. We disseminate best practice on methodology especially for longitudinal studies, case studies, and RCTs, and in designing, implementing and evaluating interventions.

CDL’s innovative and influential research is recognised worldwide as outstanding for its theoretical advances, methodological rigour and applications to early and primary education. Our research bridges the gap between theory and practice because it is focused on questions of wellbeing and achievement that matter to policymakers, teachers, families and children. Some of our work synthesises cross-linguistic and cross-cultural trends in the study of children’s learning and is redefining traditional conceptualisations about education and the developing child. Our research has had impact on educational policies in the UK and other high- and low-income countries.


Research conducted by this group on the ‘Reasoning First’ programmes have been taken up by more schools in the last year and continue to have an impact through the National Centre for Excellence in Mathematics Teaching (NCETM). The NCETM was a partner for one of the group’s previous EEF grants to assess the effectiveness of the programme Mathematical Reasoning in Year 2; 160 schools participated in this project and used the programme. The NCETM is now using it as a preparation for their Mastery Teaching in Mathematics. This approach is being tested in 50 schools.

Some of our research aims to understand how deaf children learn to read and write and learn mathematics in primary school. Find here some assessments and materials that have been developed to support children’s learning.

Members of our group work in partnership with Oxfordshire County Council to support Early Years staff in improving practice in their own centres along with practice in nearby settings. The programme centres on the use of observations to improve practice, including the use of the Early Childhood Environment Rating Scale-E (ECERS-E) and the Sustained Shared Thinking and Emotional Well-being Scale (SSTEW).
