“…In an attempt to improve a country's international standing, its mathematics education policymakers may borrow policies which were developed, and perceived to be effective, in other nations without due regard for the contexts in which the policies were initially operating (Nguyen, Elliott, Terlouw, & Pilot, 2009;Winstanley, 2012). Limited cognisance may be taken of the support structures that ensured the success of the policies, the 5 different cultural contexts in which they were situated, the effect of policy borrowing on the coherence of existing mathematics education provision (Clapham & Vickers, 2018), or the power of PISA scores to predict students' future mathematical behaviour. The propensity of some countries to borrow mathematics education policies from high-performing jurisdictions in PISA is exemplified by England's recent preoccupation with mathematical education in East Asian regions, such as Shanghai and Singapore.…”
