Which quality helps in establishing rapport with students during instruction?

Establishing rapport with students is crucial for effective instruction, and personal appearance can play a significant role in this process. When an instructor presents themselves in a professional and approachable manner, it helps foster a sense of trust and respect among students. A well-groomed appearance can make an instructor appear more credible and can enhance students' comfort levels in the learning environment.

While utilizing humor can create a relaxed atmosphere, and high energy levels can keep students engaged, these elements may not have the same foundational impact on establishing initial trust as personal appearance. Similarly, expert knowledge is vital for effective teaching but does not inherently facilitate connection with students. Therefore, a positive and professional personal appearance significantly contributes to building rapport.
