Professors who teach courses in English writing, do you show leniency in grading papers by students who aren't native speakers?
This is inspired by a recent post asking about the writing/literacy crisis in colleges. I'm a science major, and one way or another I've ended up reading a significant amount of work written by my peers. The quality of writing by some of them is extremely poor. I hope it is not controversial to say the poorest English writing I have read has come from students who are non-native speakers. What do professors do when they have to grade work by students who try their best, but unfortunately do not have a proper grasp of English? Even science majors have to take at least one non-science writing course by the end of their first year where I go to school. Are grammar and syntax overlooked in certain cases, or do many students struggle and fail in these first-year courses?
