A new research brief by Jennifer L Steele and colleagues, published by the RAND Corporation, presents new research on dual-language immersion (DLI) programmes. These programmes provide both native English speakers and children learning English as an additional language (EAL) with general academic teaching in two languages from kindergarten (Year 1) onwards.
In partnership with the American Councils on International Education and the Portland Public Schools in Oregon (PPS), the authors conducted a random-assignment study of DLI education. The goal was to estimate the causal effects of the district’s DLI programmes on pupil performance over time in reading, mathematics and science, and on EAL pupils’ reclassification as English proficient.
PBS allocates immersion slots using a random-assignment lottery process for those who apply to the programmes. The study focused on 1,625 DLI lottery applicants in the kindergarten cohorts from 2004–2005 to 2010–2011. Pupil achievement was tracked until 2013–2014.
Key findings of the study were as follows:
- PPS pupils randomly assigned to dual-language immersion programmes outperformed their peers on state reading tests by 13% of a standard deviation in grade 5 (Year 6) and by 22% of a standard deviation in grade 8 (Year 9).
- Immersion-assigned pupils did not show statistically significant benefits or deficits in terms of mathematics or science performance.
- There were no clear differences in the effects of dual-language immersion according to pupils’ native language.
- EAL pupils assigned to dual-language immersion were more likely than their peers to be classified as English proficient by grade 6 (Year 7). This effect was mostly attributed to EAL pupils whose native language was the same as one of the two languages taught.

An intervention that trained teachers to improve and monitor the quality of classroom talk had a positive impact on primary pupils’ test scores in English, maths and science, a report published by the Education Endowment Foundation (EEF) reveals.
Seventy-six primary schools with higher-than-average proportions of disadvantaged pupils took part in a randomised control trial of the Dialogic Teaching intervention, which is designed to improve the quality of classroom talk as a means of increasing pupils’ engagement, learning and achievement. Year 5 teachers in 38 schools (2,493 pupils), and a teacher mentor from each school, received resources and training from the delivery team and then implemented the intervention over the course of the autumn and spring terms in the 2015/16 school year. A control group of 38 schools (2,466 pupils) continued with business as usual. Following the intervention, pupils were tested in English, maths and science.
The results showed that pupils in the intervention schools did better in the main outcome measures of English (effect size = +0.16), science (+0.12), and maths (+0.09) when compared with pupils in the control schools who didn’t receive the intervention. For pupils who received free school meals, the intervention had a higher impact on maths (+0.16), but around the same for English (+0.12) and science (+0.11). Teachers reported positive effects on pupil engagement and confidence, and on the whole the intervention was highly regarded by participating schools. However, some teachers felt that it would take longer than two terms to fully embed a Dialogic Teaching approach in their classrooms.
The Dialogic Teaching intervention was developed by the Cambridge Primary Review Trust and the University of York. This University of York news story has more.
