One of the problems with expert teachers is that they can make teaching look easy, yet nothing could be further from the truth. The reality is that expert teachers make a conscious effort to ensure that their teaching intentions are in accord with the learning expectations they have for their students.

The casual observer does not necessarily recognize the skill in how a teacher, for instance, responds to a thoughtful question from a normally quiet student and how that may be very different from the ‘standard response’ to a commonly inquisitive or talkative student. Expert teachers are aware of what they are doing; they monitor and adjust their teaching behaviors to bring out the best in their students.
