Determiners are used slightly differently by expert and novice writers. When there are two grammatically acceptable forms (e.g., all of the students / all students or few of the students / few students, etc.), usually the shorter form without the definite article is applied by expert writers, frequently followed by a prepositional phrase which specifies its reference. On the other hand, novice writers prefer the longer form (e.g., all of the participants), without further specification. An obvious advantage of avoiding the use of the definite article in such phrases, as long as the reference of the item is clear (because the presupposed item is easy to recover or is close enough) is that it relies more on the lexical aspect of the cohesive connection – and thus allows for longer distance references. As for determiner use in RAs, it was clear that experts do not only avoid using the definite article, but at the same time, make ample use of methods for specifying what exactly they mean by those determiners (e.g., all participants in Group1). Expert writers make use of brackets to provide information for clarification (about twice as often as novice writers do). For a home assignment, therefore, teachers may ask students to collect sentences or paragraphs from RAs where writers specify the reference of a determiner in brackets, preferably on separate pieces of paper for each instance. Then, a 10-minute follow-up discussion in class may involve categorizing these instances in groups on posters, for example.
