Inquiry and mixed attainment classes
Mathematics is the most heavily setted subject in the secondary school curriculum. The last reliable figures published for England show over 80% of classes for students aged between 11 and 14 were set and, no doubt, the percentage was higher for older secondary students. Mike Ollerton characterises setting as "educational apartheid" in which the powerful exercise control over the powerless. Bottom set students are taught "repetitive, procedural, fragmented, disjointed, simplified mathematics" (Watson et al.); top set students are accelerated through the curriculum often to their detriment (see here for a selection of research papers).
It is, therefore, welcome that more maths departments today are considering mixed attainment classes. However, an examination of the reason for the growth of interest suggests there remains cause for concern.
The main reason is the mastery movement’s promotion of mixed attainment teaching. Supporters of mastery argue that students should move through the curriculum together, studying the same topics from the same materials. Yet, students are not treated equitably in the mastery classroom. Only when a topic has been 'mastered' do students get the opportunity to solve problems and reason deeply. Inevitably this two-stage model of learning leads to a two-tier classroom. Students who do not master a topic as quickly as their peers are denied access to the creative aspects of mathematics. As NRICH says here, mastery "may be insufficient for developing the potential of young mathematicians."
The problem with the mastery approach is its insistence that solving and reasoning provide an opportunity to apply new knowledge; it rejects the notion that learning can occur in the process of solving or reasoning. Yet, it is precisely when students are involved in a mathematical process that learning new knowledge becomes relevant and meaningful.
Inquiry Maths was devised and developed in mixed attainment classrooms. Its design is ideally suited to promote learning at multiple levels:
Mixed attainment classes have their roots in social justice. Justice is not served by restricting one set of students to knowledge acquisition, while their peers are involved in creative pursuits. The philosophy of inquiry, in contrast, promotes inclusiveness, cohesion and equity.
