Which of the following is an example of a non-verbal communication form in educational settings?

Body language is a prime example of non-verbal communication in educational settings. It includes gestures, facial expressions, posture, and eye contact, which are critical for conveying information and emotions without the use of words. In a classroom environment, teachers and students constantly interpret each other's body language to understand engagement, understanding, and responsiveness.

In contrast, written tests, verbal instructions, and text-based discussions all rely on the use of language, whether spoken or written, to convey information and assess learning. While these forms of communication are important in an educational context, they do not fall under the category of non-verbal communication. Understanding the significance of body language can enhance the effectiveness of teaching and learning by adding a layer of meaning that complements verbal communication.
