Ever had a "bad" teacher?

I certainly do not consider myself an expert in the art of teaching, however, I am aware of the effect I produce over my students. I can say that I have had excellent professors and also those that should have never been provided with a teaching degree. You see, the art of teaching is not simply having all the knowledge in the world, it actually involves human-like qualities which will enrich the classroom and your students. Many teachers are on the right path; which is to have your students' interests in mind, not to display your so called intellectual persona and leave an empty slate through the learning process. As a teacher, your primary goal is to "teach", not to sit back and critize the wrongdoings of your students, when you haven't actually taught them how to correctly apply the aspect in question. I deeply critize this approach some of my collegues are using when they teach, if you can call it that. It is extremely offensive to walk into a classroom with a brilliant mind that knows not how to transmit his or her knowledge. It is offensive, because it is a waste of talent that could be passed on to others in order to create a more successful environment. It is shame that many classrooms are filled with these intelligent, yet soulless professionals. Why soulless? Well the answer is quite simple, if you diminish someone's ability and talent because they do not meet your exact expectations, you are exactly that... soulless. You cannot expect, nor suggest that a student will relate to you when you are disrespectful and practice the art or demoralizing others. A teacher that knows absolutely nothing, but loves children is not adequate, but neither is a brilliant person that does not love to teach. A real and successful teacher is that person that knows a bit of everything and loves what they do. What is life without the passion of living it? What is a so-called teacher without the aspiration to see his or her pupils shine? A life without passion is just another empty tomb, that lays unvisited. A teacher that does not want to see his or her students succeed is a egocentric. Knowledge and information were meant to be shared and explored not locked up and ignored. I can only say that I am certainly glad the "bad" professors came later on in my already established career, and though they have disappointed me, they did not have a say in who I am today.
