Eye contact can make or break communication with others. It signals interest and respect for others. Teachers typically stand or sit at the front of the room. You have the ability to look at each of your students throughout the duration of the class. Making eye contact lets the students know that you are interested in what the students have to say. Avoid rolling or squinting your eyes, even if you are upset with your students.
One of the most powerful expressions is the smile. It lets students know that you enjoy working with the class, you are happy and relaxed and you seem approachable to your students. It is easy to take smiling too far, which can have negative results. Teachers should also utilize an open, receptive expression. Eyes wide, lips slightly parted and direct eye contact lets your students know that you are receptive to responses or ideas. Avoid letting negative emotions play into your facial expression. This can make a situation worse, especially if a student is trying to upset you. The poker face or "straight face" can be helpful in those types of situations.
Gestures can punctuate or underline ideas you are verbally communicating. Gestures in the classroom can mirror the types of gestures you make when having a conversation. Nodding your head and speaking with your hands shows students you are interested in the topic you are speaking about. Teachers who do not utilize gestures often appear stiff or boring.
Standing at position in the front of the class room is a powerful indicator that you are in charge and require the attention of your students. You should move around the classroom as you speak. This shows your students that you are interested in all of the class, not just the few who sit at the front. Moving around the room also indicates that you are in charge of the entire room, if a student is goofing off in the back, the student will also receive your attention.
Vocal elements such as tone, pitch, loudness and inflection are forms of nonverbal communication. Practice changing these elements of your voice at home or in the empty classroom. Avoid speaking in a monotone, which tells students you are unexcited about your subject of conversation. Avoid speaking too loudly, softly or quickly. All of these elements can strengthen your teaching abilities when utilized together.
