So totally with you - I can take extremely robust criticism of my research, but I am probably over sensitive to student criticism of my teaching.
I think it's because I put so much of myself in an informal way into my interactions with students, whereas my writing is more distanced and professional.
And also that students can be total fuckwits about how they think they should be taught. But really, how much do they actually know about what is best for them?
I had a student give me "feedback" in a really patronising way - the charmer said to me: "I need to talk to you about your teaching style. It's not inclusive." This 2nd year undergrad then went on to explain to me that "There are different learning styles you know." Oh no, I did not know that in all my 30 years of teaching in three different countries. This is a student who announced before making a definitive comment in a class discussion, that they hadn't actually read the required reading, but that they thought X nevertheless.
We can choose how we get feedback on our modules - we can use an anonymous survey but we don't have to. If I'm teaching an optional module with only 20-25 students, I set up a discussion in the last class of each module, and I ask them specifically about what worked for them in the module, and any suggestions for tweaks which might be helpful for the next year's cohort.
This is usually a really useful discussion - it's about organisation & content, not about me. And interestingly, several students disagreed with the the charming student who deigned to teach me about teaching, and said that things that student had objected to, were actually quite useful for them. I did comment at that point that in my experience, a class of 25 students will contain a variety of learning styles, and I offer a variety of activities & assessments.
As you can see from my tone, I am impotently furious about this patronising student, and obsess about this one student, whereas at least another dozen students specifically thanked me for the module.
Argh! why ???? I wish I could bulletproof myself against such thoughtless & ignorant undergrads.
