If an administrator observes a teacher and comments that the teacher needs to incorporate more non-verbal communication, then the teacher should increase her use of _______________.

To enhance non-verbal communication, it is important for the teacher to focus on both gestures and facial expressions. Gestures involve the use of hands and body movements to convey meaning or emphasize points during instruction. This can help to engage students and make learning more interactive, as visual cues can aid in comprehension and retention of information.

Facial expressions play a critical role in conveying emotions and reactions, which can help students understand the tone and intent of the teacher's message. By varying facial expressions, a teacher can indicate enthusiasm, concern, or encouragement, creating a more dynamic and supportive classroom environment.

Incorporating both gestures and facial expressions allows for a more comprehensive approach to non-verbal communication, making the teaching method more effective and engaging for students. This multifaceted strategy can lead to a richer learning experience, as students may respond more positively when teachers use diverse non-verbal signals to support their verbal communication.
