You mean you actually have a wall to put a display on? :)
Sorry, its not the reply you wanted or needed.
I had a portion of a notice board until last spring term. I had basically two things on it - a large poster about whether Psycology could be considered a science ( as per one of the controversies in the exam paper) and a smaller poster on statistical tests and choosing the right one. In addition to that I had a small notice about the EPQ and a couple of funnies - one was a cartoon about the difference between scientific research and politically biased research and one was a positivist thing about reinterpreting failures.
Cant be more help. Lost the noard to another dept ( together with my dedicated classroon
.So , now I have nothing ..... do I care? Well yes in a way, I cant advertise my subject to recruit but then no, because I dont have to be present at open morning to sell a subject when I have neither a space nor a subject board! Cuts both ways.
