- I received 37 responses - must be quite a hot topic.
-
- Q1: No = 21 Yes=16
-
- Of the "Yes" answers, more than half said that they handled OHP rollers
- reluctantly. Most respondents did not clean them, but threw them away
- (a few admitted shamfacedly to adding to the world's burden of waste
- plastic but suggested that the paper toweld saved migh be some meagre
- compensation).
-
- Cleaning rolls seems to be the responsibility of students on what seems
- to be quaintly termed "work study programs" (an alien concept here).
- Everyone agreed that it is dirty, mind-numbing and altogether unpleasant
- work. [Our experience here is that cleaning and drying a 50 ft roll takes
- about one hour and we go through 2-300 rolls per day].
-
- All respondents agreed that in most cases cut sheets were more economical,
- easier to handle and prepare, and more convenient. Rolls were especially
- useful in computational subjects where long strings of equations need to
- be derived.
-
- WHY WAS THE SURVEY CONDUCTED?
- At this university OHPs have always had rollers and the acetate rolls have
- been supplied and replaced by this Centre. The cost has spiraled out of
- hand as we now have over 60 centrally time-tabled rooms and are planning more.
- The old OHPs are falling apart and most manufacturers these days do not
- supply rollers. We are trying to rationalise their use as a "standard"
- lecture room accessory, but many faculty members object, insisting that this
- technology is essential to their teaching. Some, I suspect, are objecting
- to the idea of change per se.
-
- You may be interested to hear that the Hong Kong University record for
- OHP rolls usage is 150ft in a one hour lecture (that's three rolls!)
- If I do not hear from any competing claimant within 24 hours I will
- submit it to the Guinness Book of Records.
-
- Thanks to all who responded. Your remarks were sumarised for our
- Committee of Management which agreed to rationalisation accompanied by
- a training program for staff on better ways to use OHPs.
