USING THE DEWIS-R INTERFACE TO CREATE STATISTICS E-ASSESSMENTS

We report on the creation of statistics e-Assessments using the Dewis-R interface. Dewis is a fully algorithmic open-source e-Assessment system designed and developed at the University of the West of England, Bristol (UWE). Dewis’ ability to communicate with the R statistical programming language greatly facilitates the task of generating bespoke datasets and their subsequent analysis. The Dewis-R interface is an e-Assessment authoring tool where the questions are composed using a simplified Dewis question structure. This simplification is possible since the statistical computations are performed by R and not Dewis. As such, Dewis supplies the administration of the assessment but not the computations. Examples of e-Assessments will be presented that demonstrate the Dewis-R interface syntax and facilities.

The work is part of an ongoing UWE Learning & Teaching project to create an e-Assessment community of educators who will be able to author and share relevant, authentic and engaging statistics e-Assessments that enrich the learning experience of students. The authors welcome contact from any such interested parties.
