In this talk, I will discuss how lower secondary students’ understanding of, and progression in, algebra. I will draw on evidence from a nationally representative sample of students in England conducted as part of the Increasing Competence and Confidence in Algebra and Multiplicative Structures (ICCAMS) study. I will compare this to the Concepts in Secondary Mathematics and Science study on which the study was based. In addition, I will discuss the design of tasks aimed at developing algebraic understanding taken from a current large-scale intervention study.
