Plain English Summary
Background and study aims
This study evaluates the effectiveness of a primary school maths programme called the Same Day Intervention (SDI). Teachers are trained to adapt their classroom approach to maths teaching, for example using frequent modelling and an 'I do, you do' approach in class teaching. This involves the teacher demonstrating how they go about solving the problem, then the students practise by copying the teacher's approach.The aim of the study is to explore whether the intervention has an effect on key outcomes of interest. The primary outcome will be maths attainment as measured by a maths test at the end of Year 5. The secondary outcomes will include a measure of teacher workload, as we might expect to see a reduction in this due to marking being completed rapidly during the school day.
Who can participate?
Year 5 Teachers and their students in schools in the North of England will be included in the trial.
What does the study involve?
Schools will be randomly allocated to one of two groups. In the intervention group, Year 5 teachers will be trained in the SDI maths teaching technique and will use it in all Year 5 maths classes for the duration of the school year. In the control group, teachers will continue to teach maths as before. At the end of the school year, students will be asked to take a maths test, and we will compare levels of maths attainment for the treatment and the control students. We will also ask teachers about their workload and their perception of their students’ confidence in maths, and compare results in treatment and control schools..
What are the possible benefits and risks of participating?
SDI is designed to help maths learning and prevent students from falling behind in their understanding. There are no potential risks.
Where is the study run from?
National Centre for Social Research (NatCen) (UK)
When is the study starting and how long is it expected to run for?
The study started in 2018 and will finish in 2020.

Same Day Intervention – the effects of introducing new maths pedagogy on Year 5 students’ maths attainment, teacher workload and teachers’ perceptions of students’ confidence in maths’
Primary research question:
What is the impact of SDI on maths attainment of Year 5 pupils in England and how does it differ by FSM eligibility?
Secondary research questions:
To what extent does participation in SDI affect teachers’ workload?
To what extent does participation in SDI affect teacher perception regarding students’ confidence in maths?
What is the impact of SDI on the size of the gap between higher-achieving and lower-achieving Year 5 pupils?

Year 5 pupils learning maths
The study is a two-arm cluster (school-level) randomised controlled trial, with schools randomly assigned to intervention (Same Day Intervention [SDI]) or control (business-as-usual maths classes).
Teachers in intervention schools receive training and access to resources and support and, where possible, teaching assistants will be trained to support. In addition, the Senior Leadership Team will create the structural change to the school day as needed. Teachers demonstrate a topic, before pupils are given five or six diagnostic questions to complete independently. There is then approximately 15 minutes 'pit stop', during which teachers mark pupils’ work, and pupils either attend a short assembly or are led in an activity by a teaching assistant. After the break, pupils are grouped according to their diagnostic activity performance and there is an intervention session designed to target pupils who need extra teaching, address common misconceptions and embed learning. All regular maths classes will be replaced with SDI maths classes. The total number of classes per week may vary slightly by school. The intervention started in late October 2018 and finishes in early June 2019.
Students in control groups will receive maths classes as usual.
Primary outcome measure
Year 5 student Maths attainment, as measured by GL’s Progress Test in Maths, which will be taken in June-July 2019 (i.e. at the end of the intervention)
Secondary outcome measures
1. Teacher workload (teacher time spent marking maths work)
2. Teacher's perceptions of student self-confidence in maths
These measures are being collected using a bespoke teacher survey in June-July 2019.
