The visiting teachers from Shanghai are the second group to come to England as part of an ongoing exchange between the Department for Education and the Shanghai Municipal Education Commission, the highest-performing jurisdiction in the world for maths.In November last year, 29 maths teachers spent a month working closely with teachers in primary schools across England. English teachers say techniques introduced by their Shanghai colleagues - such as spending longer on topics before moving on and ‘teaching to the top’ through whole-class teaching - have had a positive impact in their schools.School Reform Minister Nick Gibb welcomed the arriving Chinese teachers, “The Shanghai approach - with children taught as a whole class, building depth of understanding of the structure of mathematics, supported by the use of high-quality textbooks - is proving a hit in those schools in the country where it’s been tried.”The teachers will spend 3 weeks in selected primary schools. The exchange’s focus on primary-level maths mirrors the emphasis Shanghai teachers place on establishing core skills at a young age to give pupils a sound basis for moving on to more advanced concepts.In September 2014, 71 maths teachers from across England travelled to Shanghai to spend time with their exchange partners in high-performing schools and colleges across the region.
