Student participation in post-compulsory STEM subjects is declining and limited to a small representation of society. Students are frequently choosing not to study STEM subjects because they are unable to visualize themselves as STEM professionals. The current school science curriculum in Australia isn’t of interest or relevance to many students who perceive being a science person as incompatible with their identity. Recently established Science Specialist Centres aim to change this by providing engaging, hands on experiences that show students the relevance of science in their lives and the variety of roles and tasks involved in STEM careers. This project will investigate whether participating in such programs at a science centre over a year can affect students’ ability to visualize themselves as possible future STEM professionals.
