Who is the Roles & Situations poster for?
Roles & Situations belongs to the Psychology section rather than to a school year, because life science is not something one grade owns. Anyone learning social can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Roles & Situations poster?
Often cited as proof that roles overwhelm character. The methodological critique is substantial. A wall chart earns its place by being glanceable from where the work is happening, so Roles & Situations belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
