I want to say something here in defense of my colleagues in the Humanities and other ‘writing’ fields.
As a math professor at a major university I’m extremely fortunate, as assignments are generally not difficult to grade and my classes are not huge. Still, being careful (which I try to be) makes grading a long and tedious chore. My colleagues in the writing fields, especially those with large classes, are faced with a backbreaking grading load. Especially for something like “English 100” (or whatever it is called in any given school), where students need to write great deal to become proficient, and modern teaching methods encourage us to adopt homework strategies that mean multiple rewrites, and therefore multiple reads, for each assignment.
The grading “tricks” recommended in practically every “how to survive college teaching” guide - books, forums, etc – involve scanning papers, looking for key points instead of close reading the submission. The purpose of the assignment is not to tax the professor, but to give the student practice in writing, and the points of grading – feedback on key points, and evaluation for the grade – can often be done successfully with such superficial scanning.
The “chicken” thing – if it actually happened – should have be caught, of course, though I can imagine situations where this kind of thing can slip through the cracks.
As for the original post about syllabi: I can certainly see this happening. Some syllabi are more detailed than others, and some of the language in syllabi is there for legal reasons and not that important for the students. (For example, I once had a dean who wouldn’t help me report a student who cheated because I didn’t have “do not cheat” in my syllabus.) I do wish that students with questions about things like how much exams count for the grade would look at the syllabus before emailing me, but even if they read the syllabus carefully at the beginning of the semester there’s no reason why they should remember the answer by the end.
I used to put “read the instructions” tricks in my exams (such as “the answer to problem 6b is 42”), but at some point I grew up and realized that that kind of thing centers the professor, and doesn’t really advance the main goal of an exam, which is to evaluate what the student has learned in the class.
(Edited to correct a mistake that lipped through the cracks.)
