I have been marking a lot of work recently - about 70 EMAs and a large number of final TMAs. Something that strikes me is issues around use of sources and referencing.
One issue is that many students overquote and some even seem to think that there is only a need to reference if they quote. This seems a quite ineffective way of referring to knowledge of the course. The references are often too wordy for the point they need to make. Sometimes they do not make sense out of context - e.g. writing "now" or even "yesterday" when the student's work is about the situation a few years later.
Another issue is that many students put a full stop before a reference when the reference finished the sentence. Sometimes students even put a full stop before and after a reference. This seems to suggest that they consider the reference as being apart from the rest of the sentence rather than an integral part of the text.
These perhaps suggest that there need to be new ways of presenting how sources are used in academic contexts.
