Efficacy

        So to be honest I have never heard of this word.  I thought that it was supposed to be efficiency at first then I realized that the rest of the question doesn't really pertain to this word. But the definition of efficacy is, "the ability to produce a desired or intended result." Now that I know what this word means, I can see that it is a valuable virtue to have as a teacher. A teacher needs to always have a plan and then know how to execute it in order to get the point of the lesson across to the students. Teachers need to have confidence and persistence in what they are teaching. If their students don't understand right away, try again but in a new manner. Teachers cannot give up, it is not in the job description. If Someone is not willing to work hard, make mistakes and learn from them, then they should be teaching.
       These attributes take time and experience though. New teachers cannot expect everything to be easy and perfect right out of school. Having a real job in the real world is a lot different than taking education classes in college. We should not be afraid to ask questions and even ask for help. No one expects perfection.
