A teacher is one who guides or leads. To guide does not necessarily mean to instruct directly. We often think of teaching as direct instruction (presenting information, asking questions, giving feedback, demonstrating some procedure, evaluating student progress, and so on). But a teacher can guide without instructing directly. A good example is the Montessori system of education. In a Montessori school, most of what a child learns is through interacting with a variety of curriculum materials in a particular context. A Montessori teacher does much less direct instruction than do teachers in traditional schools. References: Frick, T. (1991). Restructuring education through technology.
