On one of our large programmes most of the modules are coursework based. For each of those modules there is an opportunity for a formative submission prior to final summative submission (of around 500 words which has written feedback but no indicative marks). Around three quarters will take the opportunity.
Is this the norm across the sector? It appears to have crept in over the past few years at my place - adding to already difficult academic workloads. We used to restrict this to first years who were finding their academic feet - but it's now across all years.
