Implementation support strategies such as professional development (PD) are pivotal in guaranteeing the assistance that teachers need to enact mathematics teaching innovations and to secure lasting change. Within large-scale efforts an important issue for researchers is to understand how to design and put into effect these implementation support…

Generalisation is a skill that enables learners to acquire knowledge in general, and mathematical knowledge in particular. It is a core aspect of algebraic thinking and, in particular, of functional thinking, as a type of algebraic thinking.
