Humility

I have been wrong plenty of times in my life. Usually it is when I think I am right and I think I can prove it but then I can't. I think the balance would be that admit what you know (that's where the confidence comes into play) and then admitting that you don't know everything and that you are wrong sometimes (that's where genuine humility comes in). There are times when teachers will have to admit that they are wrong and can't always know everything.

Collaborativeness

I think for a highly effective team or group, they have to be able to communicate and be able to have everyone imput their own ideas. I think that the difference between collaboration and group work or cooperative learning is that with collaboration people are coming together to with different ideas rather than just one. Like in group work or cooperative learning. With group work and cooperative learning, it is all about coming together with one idea or concept.

Efficacy

I think that every teacher has to be confident and have persistence. Other wise students will not listen to their teacher if they do not have confidence in themselves or what they are teaching. Teachers that have persistence will last longer in a classroom and won't have students walk all over them. I've had teachers that weren't persistence and would tell students what to do and what not to do. And then she would never follow through on her rules. So students would walk all over her. I think that these attributes are best developed through years of teaching. You learn what works and what does not work and what they need to work on in their classroom.
