The Education Endowment Foundation has published the results of a randomised controlled trial of IPEELL
The IPEELL intervention is a writing process model in which pupils are encouraged to plan, draft, edit, and revise their writing. IPEELL stands for Introduction, Point, Explain, Ending, Links, and Language. The strategy provides a clear structure to assist writers and can be used for most genres of writing, including narrative writing. In addition to the writing process, the IPEELL intervention also involves ‘memorable experiences’ for pupils designed to act as a stimulus for their writing.
The trial tested the impact of one year of IPEELL for children in Year 6 and the impact of two years of IPEELL for children who started it in Year 5 and continued in Year 6. In total, 84 schools and 2,682 children in the north of England participated in the one-year trial and 83 schools and 2,762 children participated in the two-year trial. Writing outcomes were measured using Key Stage 2 (KS2) writing outcomes for the one-year trial and a bespoke writing test based on historic KS2 writing tests for the two-year trial.
The results showed that pupils who used IPEELL for two years made more progress in writing (effect size = +0.11) than pupils who did not. However, they made less progress in reading, spelling and mathematics than pupils in the control group (ES = -0.17—0.30). Pupils who used IPEELL for one year made less progress in writing, reading, spelling and maths than comparison pupils.
A previous trial of the approach had shown large positive results, but there were important differences between the two trials. In this latest trial, the model used teacher trainers who had never seen IPEELL delivered in the classroom. It also measured the average impact across all pupils, while the first looked only at pupils with low prior attainment. In this latest trial, pupils with low prior attainment who used IPEELL for two years made more progress in writing (effect size = +0.26) than pupils who did not – a larger effect size than the figure for all pupils.
