ab: Summary: We demonstrate how the DEWIS e-Assessment system may use embedded
R code to facilitate the assessment of studentsâ€™ ability to perform
involved statistical analyses. The R code has been written to emulate
SPSS output and thus the statistical results for each bespoke data set
can be generated efficiently and accurately using standard R routines.
This enables studentsâ€™ answers, generated from their application of
SPSS, to be marked and appropriate feedback supplied back to them
automatically. Staging is used between different parts of the
e-Assessment to replicate the natural stages of a complete statistical
analysis. This allows students the freedom to work away from the
e-Assessment; they may view the relevant stage an unlimited number of
times prior to submitting their answers for that stage. The technical
challenges of setting up the e-Assessment in this way are discussed as
well as the rationale for adopting this pioneering approach.
