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.
