Designing an information visualization dashboard to proctor test-takers during language certification online testing

ABSTRACT

The learning mechanisms and the evaluation process have been moved to an online mode in order to maintain social distancing and reduce the spread of the COVID-19. E-learning initiatives (including assessment and proctoring) produce a large amount of data, so visualization mechanisms are required to support the decision-making process. This problem is addressed from a practical context of study the English Language Certification Tests of a University in the southeast of Mexico. The conceptual design of four conceptual dashboards are presented using a mixed methodology: the UCD process and a conceptual model for a dashboard generator process. The four conceptual dashboards were evaluated by five experts. Although the design proposals were simple and reflected most initial user requirements, the experts suggested to include more elements in all the dashboards to provide the information needed for the intended users and improve the decision-making process. © 2021 ACM.
