Teaching is not only speaks to other people about certain knowledge. Teaching has two parties. So, two parties will talk each other. The talk is one kind of communication. When we are teaching, we are meeting other people to accept our knowledge. There are lecturer/teacher and students.They would do speak each other that we called it as a communication. Such as mention above, teach is not about speaking to other people or talk about certain topics. There are two aspects of teach; first, deliver knowledge or information to other people.Second, transfers of certain values or principles about life in topics area that we had choose. The values will transform to the circumstances that we want it happen in the future.
