A randomised controlled trial, published in the Journal of Educational Psychology, has examined the impact of a version of the PACT reading comprehension and content acquisition intervention, which was modified to meet the needs of pupils with English as an Additional Language (EALs), in eighth-grade (Year 9) social studies classes.
Sharon Vaughn and colleagues carried out the trial with schools with moderate to high concentrations of EALs. In the selected schools, all eighth-grade (Year 9) social studies teachers participated, and classes were randomly assigned to the treatment or comparison condition. Each teacher taught both PACT treatment classes and comparison classes, and the same social studies content was delivered to pupils in both conditions, but with the interrelated components of PACT included in the treatment classes.
Pupils in the treatment group did better than pupils in the comparison group on measures of content knowledge acquisition and content reading comprehension, but not general reading comprehension. Both EALs and non-EALs who received the intervention performed better on measures of content knowledge acquisition (effect size = 0.40) and content-related reading (effect size = 0.20).
