This session will introduce research being applied under the umbrella of a community of practice in three schools in the ACT. The ELPSA lesson design framework is consistent with how we learn most things in life, providing a structure identifying how mathematical concepts and understanding are acquired and developed. ELPSA, providing the core of an action research project investigating teacher beliefs and practice in the ACT, represents five learning components, namely: Experience, Language, Pictorial, Symbolic and Applications. Alongside ELPSA the project promotes student engagement, non-verbal communication, reasoning, perseverance and tasks involving multiple entry and exit points for all students. Some practical examples involving a range of subject areas and year groups will be discussed alongside opportunities to share and commence developing resources.
