An inclusive school providing a safe, inspiring setting for children to flourish. It may not have always been exactly like that, but it is now!

Operating as usual


this just in...

Hi...I am going to try to have a reunion of classmates of...wait for it...4B of 1960/61.
Our form teacher was a wonderful chap ..Mr Dawson.
Less said of the then Headmaster called Coales the better.
Some of us attempted this some 30 years ago, but it unfortunately came to nothing.
As all of us of that year are 70, or approaching that age, it's now or never.
Could I post something on the school's FB page to get the ball rolling.
thanks in advance

NetLogo Models Library: Virus 21/03/2020

Back in the day when I* ran coding clubs at the school, one of the programming systems I never quite got around to teaching was Netlogo. I've been looking at it again in the light of the current coronavirus events. Netlogo is a simulation software package - and it, it comes with a variety of simulation models, such as this one:
It may be of interest to some of you - especially anyone who used to go to the coding club sessions.

* ("I" = Gordon Campbell. This was a page I set up for CJS some time ago, but they are not using it. I was going to delete it but decided that it may be useful for people to connect. For some reason, this post may look like it's official school business, but it's just me :) )

NetLogo Models Library: Virus Ecological biologists have suggested a number of factors which may influence the survival of a directly transmitted virus within a population. (Yorke, et al. "Seasonality and the requirements for perpetuation and eradication of viruses in populations." Journal of Epidemiology, volume 109, pages 103-...


This page was created by me (Gordon Campbell) when I was responsible for the school's IT support, but as with Mrs Campbell, the previous head, I've been pretty much retired since then. Anyway, I've been contacted by the school who were wondering who owned this page. The school does not currently wish to use the page and I'm sure that it won't be missed, so this post is just to say, so long, farewell, I bid you all adieu, etc. It'll be sent to the great electronic bin fairly soon now, once I get around to working out what to do😚.


Mrs Campbell is leaving! She would love the company of any ex-pupils/ex-members of staff on Thursday 21st July 3.30-5.30 - please pass on!
