1. Introduction

Mathematics is a core discipline that sits at the heart of primary and secondary education in the UK. Despite this, it has recently been noted by Andreas Schleicher, the Education Director of the Organisation for Economic Co-operation and Development (OECD), that if the UK education system continues to progress at its current rate, “it would take a very long time to catch up with the highest achieving countries” [1]. These remarks were in response to the UK’s performance in the Programme for International Student Assessment (PISA) 2018, an assessment conducted every three years, across 79 different countries, which explores the abilities of 15-year-olds to solve problems set in real-world contexts, in reading, science, and mathematics. In PISA 2018, the UK was ranked 14th for reading and science, but only 18th for mathematics, with students in 12 countries with maths abilities that were at least four months ahead of the comparable UK cohort [2]. Within the top scoring countries, there were gender differences in performance. In some cases, girls outperformed boys (e.g., Finland), but in most countries, including the UK, boys outperformed girls. Moreover, within the UK, the gender gap was greater than for all countries that outperformed the UK. Given this poor performance in mathematics, it is timely to reflect on what can be done to improve this in the UK. One approach is to examine practices in PISA’s top performing countries, such as Estonia, Finland, the Netherlands, and several in East Asia, and compare these to the UK.

There are, of course, likely to be many factors that have led to these countries being more successful, including performance in other areas—research suggests that mathematics ability is, in part, underpinned by reading performance [3]. However, it is not possible to examine all of these and, as such, we have chosen to focus on two core areas: 1. curriculum and assessment and 2. teacher effectiveness, considering several factors within each of these (Figure 1).

of English and Japanese mathematics textbooks, which found that whilst the English specification for geometry aims to cover various topics, the Japanese curriculum focuses solely on geometric proof using congruency. This allows for the proof to be concentrated on in depth when students learn geometry, whereas in England, the concept is dispersed throughout topics, such as number and algebra, as well as geometry, and therefore, it is never studied in detail [19].

Based on the success of these other countries, we would recommend that the UK consider reshaping its mathematics curriculum to focus only on key concepts and princi- ples, supporting in-depth study. This study should be grounded in inquiry-based learning, rather than memorisation of facts. Inquiry-based learning is associated with a number of positive outcomes, including increased student engagement [20], improved critical think- ing [21,22], a more positive attitude towards problem solving [21], and the development of flexible mathematics knowledge [23]. Furthermore, inquiry-based learning should im- prove students’ abilities to solve mathematical problems embedded in complex contexts, which can provide a more authentic experience. Within inquiry-based learning, there are a range of approaches that could be adopted, depending on the cohort. For example, problem-based learning, where students are encouraged to collaborate to solve complex, real-world problems [24] or project-based learning, where students master new material through the creation of an original product or presentation, for example, a play or video, which is typically presented to an outside audience [24]. The latter corresponds to Bloom’s taxonomy, where the creation of original work is positioned at the top of the hierarchy of learning and therefore can be argued to lead to the deepest and thus most effective learning [25].
