Humility

I am often humbled by my stupidity, my ignorance, and my social awkwardness.  But I'm okay with that.  After all, stuck-up people are the worst.  The last time I was wrong was about fifteen minutes ago when I was studying for my french test and I mixed up "faire le marche" and "faire le menage".  (Going shopping and doing chores are basically the same thing, right?)  Earlier today, I spilled chipotle sauce on my pants, wrote down the wrong rhythm while doing a rhythm dictation, forgot to modulate during my ear training hearing, and told my friend to stop speaking in an Australian accent when he was actually trying to be British (that one wasn't entirely my fault).  I am wrong a lot.

I think teachers need to be confident in their subject matter.  They need to know what they're talking about and be ready to answer any questions the students have.  However, I think that, on a personal level, they need to be humble.  Weston Noble said that the best quality in a teacher is vulnerability, which I think goes along with humility.  These qualities, I think, help students connect more to their teachers because they can see that they're human, too.

Collaborativeness

I think that effective teams are made up of people who are willing to listen and consider what others have to say.  I think that the members of the team should be creative, interesting people, as well.  In order to come up with out-of-the-box ideas, you have to have out-of-the-box thinkers.  If you have interesting people who are willing to listen, I think there is potential for some great ideas.

In my experience, group work tends to be a group of people sitting around while one person does all the work.  I think of collaboration as being more of a team effort, where everyone has input and puts forth effort.

Efficacy

Self-awareness, confidence, persistence, work ethic, and belief in one's ability are all super important traits which all teachers should try to acquire.  I think it's kind of hard to lump all of these traits into one group, so I'll split them up.  Clearly, I have excellent problem-solving skills.  Here goes.

Self-awareness is an important trait to have as a human being in general, but it's especially important to human beings who happen to be teachers.  It's always good to know how you're perceived.  If students aren't responding to you because you're super lame, it's good to be aware of your lame-ness and do something to change it so they can relate to you better.

Confidence and belief in one's ability kind of go hand in hand.  They are both good skills to have, because people tend to listen to people who seem to know what they're talking about.  If students don't think that a teacher knows their stuff, they won't think that they have to know the material, either.

Persistence and work ethic good qualities for teachers to have, as well.  Students are not always going to have an easy time learning material, or they may not want to learn the material at all.  Teachers need to be persistent so their students will learn what they need to learn.

I think that all of these attributes are either learned or inborn. Belief in one's ability sometimes comes with time and experience.  However, work ethic is kind of something people are born with, although I guess it could be learned.
