I've been an English writing tutor at a Canadian university since 2007, and many of the tutees I see are EAL learners, often thrown into university classes without an appropriate level of preparation in English. The range of difficulties varies, of course, but I recently had difficulty helping a student who was consistently using the wrong form of a word, like an adjective in place of a noun (e.g. "he was not a good diplomatic"). As a tutor, I do not want to simply give a heavy handed correction to these numerous and consistent errors, however, other than asking to study to use a dictionary for nearly every word they use, I'm not sure how to give this student some useful help and resources without being overwhelming.
I am sure this is a common experience. Are there any (free) resources, exercises, or handouts that you think might be a useful strategy with this?
Thank you so much for any advice or assistance you can give!
