An experiment; it 'worked' in general as a way for students to document their learning journey through the activities of the unit
It served as an appropriate and more engaging/dynamic alernative to "tutorial participation"
It tended (as desired) to help reward those students engaged throughout the unit
It involved extra support (e.g., via technical assistance and ongoing feedback) and final marking on the part of the instructor - and this required some technical expertise to "pull off" (i.e., successful mentor)
Additional handouts, demos (e.g., demo videos), online tutorials etc could be offered to minimise the technical barriers.
