I've just been looking around the Speak Up site and found an old discussion on whether it is appropriate for teachers to espouse opinions on things like politics and religion to students.
For what it's worth, I think it's okay so long as it's relevant. I like to get students to think and will often act as a devil's advocate, putting forward a point of view I don't agree with, just so that it is considered. I like passion, but ignorant passion is a waste of time.
Politics comes into my courses a lot - we discuss globalization and the anticapitalist movement, reasons why American visual culture is universally consumed but equally, it seems, reviled. We talk about the ideology of advertising and ways in which designers and illustrators can use and abuse the power they have. A common comment after my course is that students feel less inclined to be designers, more cynical about the industry. That's an immediate reaction, but I suspect that those who say it are more likely to go on and be good, conscientious designers. In fact, not so much conscientious as conscious.
You cannot study any subject out of context, and graphic design has a political, sociological and ideological context. It plays on and with psychology, class, taste and whatever dominant economic system is in force at the time. It can be used to tell massive truths and untruths. Making students aware of that is not inculcating them, if handled appropriately.
The comment below struck me, however, given my earlier comments about whether it was important for a design teacher to be a "good" designer themselves. This student, from the USA, thinks that it is. I have to say I've only met one student who had a problem with me not having a BA in Graphic Design, and only a handful have ever asked if I would show them some of my work (but they were all out of interest rather than to check my qualification to teach them).
The comment below suggests this student is focussing on the wrong things. Would she accept a place on a course taught by award winning designers who were inept at teaching, and reject one delivered by mediocre designers who were exceptional at realising the talents and intellects of their students?
In the UK it's traditional to look at graduating students' work, not their teachers', as a quick measure of the quality of the teaching. Even that is not without its problems (I know of a couple of courses that deliberately recruit already "good" students and then abandon them for three years, letting the staff get on with being artists and designers, so the work is effectively produced in spite of, not because of, the teaching) and efforts are in hand in the UK to change the information applicants have about courses and the quality of the teaching.
The later comment "Sometimes a student can get frustrated over a teacher's crits and question their knowledge and expertise -- if people knew what teachers were capable of early on, this line of thinking would be in the backburner" is fine - but what evidence does a portfolio show? Often the work is the result of a creative collaboration between a client, an art director, account manager, copywriter, photographer and artworker. The piece itself tells you nothing of the talent of the person who carries it in their portfolio, particularly in relation to their teaching ability. The best way to challenge a teacher's opinion is through discussion, not a duel with portfolios at twenty paces.
"I wish they had detailed information about faculty as well. Also, for some reason, the teachers I had didn't pull out their portfolio (to put their money where their mouth is so to speak) until later in the course or until asked. I think it's should be a pre-requisite for students to peruse through faculty's portfolios before deciding to go to that school.
Sometimes a student can get frustrated over a teacher's crits and question their knowledge and expertise -- if people knew what teachers were capable of early on, this line of thinking would be in the backburner. You can have a LIST of credentials, awards, and everything -- but if no one SEES the actual WORK, students are cynical and quick to judge."
