Using School-Level Data to Investigate the Impact of a One-to-One Mathematics Teaching Resource in English Primary Schools

This research investigates the potential for a one-to-one coaching tool used by adults other than teachers to be able to deliver greater mathematics progress for primary school children without adding significantly to school costs. Plus 1 and Power of 2 (+1 and Po2) are workbooks designed to be used by adults other than teachers working on a one-to-one basis with children to develop numeracy skills. This quantitative study seeks to examine the impact of +1 and Po2 by considering performance data aggregated at the school level. The attainment of children at 1071 English schools which use the +1 and Po2 products was compared with that of peers in other schools using a quasi-experimental research design based on England’s national performance measures. Statistical analysis suggests that schools using +1 and Po2 show higher levels of mathematics attainment than those who may have used other resources. Furthermore, there is an important finding that assessment attendance is higher, and disapplication from the curriculum lower, in schools using +1 and Po2. This indicates that use of this one-to-one intervention improves access to national tests for children and represents an opportunity for school leaders to maximise the cost effectiveness of existing non-teaching staff or volunteers
