Plain English Summary
Background and study aims
Philosophy for Children (P4C) is an approach to teaching in which students participate in group dialogues focused on philosophical issues. Dialogues are prompted by a stimulus (for example, a story or a video) and are based around a concept such as ‘truth’, ‘fairness’ or ‘bullying’. The aim of P4C is to help children become more willing and able to ask questions, construct arguments, and engage in reasoned discussion. P4C has been the subject of a number of studies since the 1980’s, these have had various methodologies, but have consistently shown impacts on logical reasoning and reading. The aim of this study is to find out whether the P4C approach can improve children’s reading skills, math skills and social skills.
Who can participate?
Children in year 3 and 4 in the 2016/17 academic year who attend participating primary schools.
What does the study involve?
Schools are randomly allocated to one of two groups. In the first group, schools receive P4C training and support over three years. In the second group schools continue teaching as normal and are asked not to use P4C materials during the first two years or for year 6 pupils in the third year. In May 2019, pupils at all schools undertake their key stage 2 reading tests and numeracy tests as well as completing a questionnaire about their social skills, so that the effects of the P4C program can be assessed.
What are the possible benefits and risks of participating?
Participants may benefit from an improvement in their literacy. There are no notable risks involved with participating.
Where is the study run from?
The study is being run from the National Foundation for Educational Research and takes place in 200 primary schools in England (UK)
When is the study starting and how long is it expected to run for?
February 2012 to October 2014
Who is funding the study?
Education Endowment Foundation (UK)

A cluster-randomised controlled trial of the effectiveness of a school-based philosophy programme at improving the development of literacy ability in disadvantaged pupils
The aim of this study is to evaluate whether:
1. Using the P4C approach can improve pupils’ attainment in Key Stage 2 reading
2. Using the P4C approach improves pupils’ Key Stage 2 maths attainment and social skills, measured using an adapted version of a questionnaire developed by Gorard et al. (2015) and SAPERE as part of other evaluations of P4C

Literacy attainment, numeracy attainment and social skills in children
Schools will be randomised to one of two groups using simple randomisation.
Intervention: Schools will receive training and support over three years, with the intention of reaching SAPERE’s Gold Award level of P4C practice. For each school, the programme will consist of the following elements:
1. Two days of P4C Foundation Training (Level 1) for up to 25 staff: this equips teacher to start facilitating P4C enquiries with their students, and covers the basic principles of P4C practice, the standard enquiry model and provides an opportunity to experience a model enquiry
2. One day of P4C Tools for Thinking Together Training for up to 25 staff; this provides staff with additional facilitation techniques and practical guidance in encouraging stronger reasoning and conceptual thinking among students
3. Four days of Advanced P4C Training (Level 2A and 2B) for 2 staff; Level 2A gives the school’s P4C leaders advanced facilitation techniques so that they can support colleagues who are less advanced in their P4C practice; Level 2B gives the P4C leaders guidance in how to plan for the development of the school’s P4C practice, how to link P4C into the broader curriculum and how to handle sensitive and controversial topics that may arise in an enquiry
4. Seven days of in-school P4C coaching and support; the SAPERE trainer tailors the content of these days to the school’s needs; they may include demonstration, observation or co-teaching by the trainer, or planning with the P4C leader or remedial work with teachers who need extra assistance, or specialist advice on linking P4C to literacy, for example
5. Five days of remote administration and planning support; these are for ad hoc support on the implementation of P4C and may include guidance on the Bronze, Silver and Gold award applications
6. Unlimited access to SAPERE’s online P4C resources and practice guides; these include a wide bank of suggested enquiry stimuli, a Getting Started Guide, a Moving On with P4C guide, a range of teaching materials and example enquiry plans and the Award framework which sets out a detailed progression for P4C practice across student, teacher and whole school dimensions
7. Two reference copies of SAPERE’s Level 1 and Level 2 handbooks
8. Application and assessment fees for SAPERE’s Bronze, Silver and Gold awards
Control group: Schools will continue teaching as normal and will be asked not to use P4C materials during the first two years, or for year 6 pupils in the third year.
Primary outcome measure

Secondary outcome measures
1. Numeracy of pupils eligible for free school meals, measured using scaled score from Key Stage 2 mathematics tests in May 2019
2. Social skills, measured from a social skills questionnaire administered to pupils by NFER test administrator in May 2019

Results and Publications
Publication and dissemination plan
An evaluation report describing the results of the trial and methods used will be published in Spring 2020, followed by an addendum report (with results from the following cohort of pupils) in Spring 2021.
IPD Sharing plan:
It is EEF policy that all trial data be uploaded to Fischer Family Trust, the EEF’s data processing contractor. The idea was that anonymised data would then be uploaded to the UK Data Archive for access by future researchers, but that has recently been blocked by the Department for Education. Data from this still will be held, available either from the Department for Education or the UK Data Archive.
