It’s been a long time since I last wrote on a blackboard with chalk. I remember the second school on my teacher training programme had blackboards and especially in the small sixth form teaching room. I explained arithmetic and geometric progressions in there as my A Level teaching experience.
On Wednesday 13th November 2013 I also used chalk on a blackboard. It was a pleasant experience. I particularly like the contrast of the white text on a black background, it makes the writing stand out well [when I read in my Kindle app I have the setting that way around].
You might be able to see a little bit of white-roller-board in the picture and be wanting to ask why I didn’t use that? Well, it only makes up one third of the board and I didn’t want to have to erase my notes and it was dirty and creased. I’m rather fussy about white boards and how clean they should be kept.
