The Nuffield Foundation has published a systematic review by researchers at Ulster University that analyses the outcomes of classroom-based mathematical interventions.
The systematic review included studies that assessed the outcomes of interventions aimed at improving maths achievement in primary school children. Forty-five randomised controlled trials were included along with thirty-five quasi-experimental studies. The studies were published between 2000 and 2017, and were mostly conducted in the US and Europe.
The results of the review suggest that there are effective strategies teachers can use to help with learning maths and being fluent with mathematical facts. It also found there are many different ways teachers can support children to have a wide bank of strategies to complete mathematical problems, and for children to know when is best to apply them. Technology in the classroom can also be helpful as long as these tools have been developed with a clear understanding of how children learn.
The report concludes that the evidence base on mathematical interventions is weak, and recommends that researchers should test how effective mathematical interventions are in order to help teachers support children’s learning.
