Following a private (DM) discussion on Twitter with @evestirling the following occurred to me.
If the product of students’ work is to be assessed then it’s appropriate for the HE institution to set the assessment environment and medium.
If process is the important factor, then the students should be allowed to work in whatever environment and media they want, and the institutions need to adapt their assessment processes to accommodate. The control should be with the student in the form of a PLE; not the HE institution.
Comments are very welcome on this.
