Thermal stress


I'm absolutely shattered this evening. I've just got home after finishing day 2 of a BOHS module course - M201 covering thermal environment, lighting and non-ionising radiation. Its a lot of content to cover. I've had to try to compress thermal environment into two days for an audience who have had little previous involvement with the subject.

As usual with BOHS modules there is far too much content. It is particularly frustrating in that the thermal environment section of the syllabus includes a lot of material which is well out of date, does not have much relevance to current practice and is of historical interest only.

Covering some of the older, outdated material can reinforce understanding by showing how modern approaches evolved, but that is a luxury when time is limited. It means that I can't really devote enough time to teaching and reinforcing the material that is really relevant to today's practice. It also means that I haven't much time available for practical exercises that would really reinforce learning. The outdated material needs to be weeded out so that proper emphasis can be given to the information and skills that hygienists need to carry out their jobs.

I'm afraid this is par for the course with BOHS modules.
