When technology models poor practice

Year1 assessmentOne of the difficulties in teaching first year students is to convey the importance of appropriate handling of data, both in terms of data display and degrees of significance. I’ve commented previously on this site about times when technology can produce utterly inappropriate graphic representation of results (see A bonus lesson in my data handling tutorial).

At the end of the first semester we conduct an online exam using the Blackboard quiz tool. The assessment is out of 200, marked automatically and scaled to a percentage. When the students submit their answers at the end of the test, they get  instant reporting of their result. The screenshot on the right shows a section from the gradebook where the results are recorded in exactly the detail each students gets, i.e. up to 5 decimal places! It is unfortunate that this inappropriate “accuracy” gets displayed to the students.

One recent email exchange related to someone else’s order for running shoes, sent to me in error

I’ve recently had cause to contact three different companies about inadequacies in their service. The reasons for doing so in each case were very different, but there was a common thread to their replies: “Please send a photo of the [relevant item]”. When the third request came in, I started to see a pattern and this set me ruminating on why they were adding this extra step to dealing with my query.

And then it struck me, that this was exactly the reason – it was an extra step. It is part of a filtering process. It is easy enough for all and sundry to fire off email requests willy-nilly. As a mechanism to weed out the serious appellant from the time-waster there needed to be an additional hurdle. [I have vague memories from school history lessons that monasteries used to offer a similar process. Potential novices were never admitted at their first attempt, they were required to return on several occasions before securing entry into the monastic life.]

I mention this here, on my education blog, because I actually operate a similar system when it comes to requests from students. If you are involved in academia I am sure you recognise emails, particularly as exams loom, that go something like: Continue reading
