Journal paper in T&F Assessment & Evaluation in Higher Education

October 2019 learning analytics, visualization, education

Our publication Visualizing the University Student Journey is published the journal of Assessment & Evaluation in Higher Education.

Our article reports on the work that we have been involved in which combines the concept of Learning Pictures (Lindsley 1977, All 1977) with contemporary InfoVis techniques, such as Small Multiples, in order to provide enhanced, objective guidance to examiners when making adjustment decisions. Our goal is to improve the sense making process of examiners, during situations such as annual board of studies, where dozens, if not hundreds of students need to be evaluated in terms of their overall performance.

The field of learning analytics is progressing at a rapid rate. New tools, with ever-increasing number of features and a plethora of datasets that are increasingly utilized demonstrate the evolution and multifaceted nature of the field. In particular, the depth and scope of insight that can be gleaned from analysing related datasets can have a significant, and positive, effect in educational practices. We introduce the concept of degree pictures, a symbolic overview of students’ achievement. Degree pictures are small visualizations that depict graphically 16 categories of overall student achievement, over the duration of a higher education course. They offer a quick summary of students’ achievement and are intended to initiate appropriate responses, such as teaching and pastoral interventions. This can address the subjective nature of assessment, by providing a method for educators to calibrate their own marking practices by showing an overview of any cohort. We present a prototype implementation of degree pictures, which was evaluated within our School of Computer Science, with favourable results.
