The data I have been guilty of.


Gathering and keeping data about students isn’t new. In my career, most of the data was based on the CEFR framework, which is widely used. It is, however, not ideal as language skills are notoriously hard to quantify. Based on CEFR, I, the teacher was responsible for collecting, inputting and interpreting the data. The combination of those two unreliable factors demonstrate the issue of flawed data sets that then could serve either algorithms (Kearns&Roth 2020; O’Neil 2016) and inform decisions.


I calculated the rough number of students I taught at each of institution. ‚Profile‘ refers to a written paragraph about the student that is saved and passed on. Awareness of data gathering was based on explicity – if students were explicitly informed their data was being saved and processed.


I experimented with infographic format I saw in other blogs and McCadless (2012, below).


This data demonstrates a few worrying trends, apart from the aforementioned objectivity. Students were not explicitly told about the data gathering. Worse yet, as time progressed, there was more automated and saved data but less information. This coincides with the dawn of platforms – more platforms, less awareness (van Dijck et al 2018).  Although not directly visible from this visualisation, it made me realise in the places where data was more standardised, processed, and formed basis for teaching, the faculty had no guidance or training on how to use it (Brown 2020).

  1. This is interesting, Magda, I think it very worrying that we have to jump through ethical hoops to ask a student about anything while all these data are collected on them with no questions asked. Love how neat your visualisations are.

  2. Nice visualisation here. It is great to see you continuing some useful themes, in terms of reflecting on your previous teaching, but also showing what other visualisation work has inspired your particular design. The ‘open book’ and pencil graphics work really well here I think,.
