Carpe diem -- that's one of Mr. Keating's mottos, which he tries to convey to his students. That's a major difference to other teachers, who just want the pupils to do their jobs and nothing else. That's founded on the motivations of the teachers: While most of the teachers do their job only because they have to do it, because otherwise their families wouldn't have anything to eat, Mr. Keating teaches because he is actually convinced of his job, or, to speak in Mr. Keating's words, of his profession.
Another thing to note is the way Mr. Keating teaches. While other docents are very conservative---the Latin teacher comes to my mind first ("agricula, agriculae, agriculae, agriculam, agricula, ...")---Mr. Keating rejects the old methods of teaching. For example, he asks his students to rip out the "Introduction to Poetry" by Mr. Pritchard, because he thinks poetry can't be expressed in a purely analytical way. In his opinion, poetry is not simply a sequence of verses, but instead it is art, it is culture, it is a way of life.
Another thing Mr. Keating wants to convey to his students is his idea of ideas being able to change the world, which he contrasts to rather ordinary things. In his opinion, even a single poem can and will make a difference and is able to shake the world up.
This attitude is not liked much by the rest of the teachers. They'd prefer Mr. Keating to use traditional methods of teaching, which are apparently proven to be successful. Additionally, they hold Mr. Keating responsible for Neil Perry commiting suicide.
