I have found that the facial expressions a teacher uses can also have a positive effect on classroom learning.

The face is very expressive and you can can use your expressions to great effect.
Smiling is the most powerful facial expression and students like teachers who smile a lot, because teachers who smile send out the message that:

* they like being with the students
* they are relaxed
* they are confident

Of course there are obviously times when a more serious expression is appropriate. It’s interesting that the effect of withholding a smile can sometimes send a powerful message to students that some aspect of their behaviour is not acceptable, and is often more effective than any words.

Another powerful facial expression is the open, receptive face – eyes open wider than usual, lips slightly apart. The non verbal information here is that the teacher has asked a question, or made a request for information, and is now waiting for the answer, and expects that students will give an answer.

Teachers must not to allow facial expressions to betray what might be a strong emotion they are feeling. For example if you’re frustrated by some aspects of student behaviour, that anger can be ‘written all over your face.’ Unfortunately, if students see your anger they may well respond negatively, which makes the situation worse. Every teacher has ‘been there’, but it can and does get better with practice and experience.

As well as smiling, a ‘calm, assertive’ expression works well in many situations. You don’t smile, but you don’t frown, you keep a ‘straight face’ which sends the message that you’re in control, both of yourself and the situation.
