Instructors should display which of the following types of behavior?

Instructors should display professional behavior because it establishes a respectful and effective learning environment. Professionalism encompasses attributes such as competence, respectfulness, and a commitment to fostering students' learning experiences. When instructors maintain a professional demeanor, they earn the trust and respect of their students, which can enhance student engagement and motivation.

A professional approach involves being well-prepared for lessons, actively listening to students, providing constructive feedback, and demonstrating subject matter expertise. This not only assures students that the instructor takes their educational role seriously but also sets a positive example for students to emulate in their own conduct.

In contrast, behaviors that are friendly and casual may blur the lines of student-teacher relationships, whereas indifference and distance can lead to disengagement and lack of connection. Similarly, being authoritarian and strict may foster fear rather than respect, which can inhibit open communication and collaboration in the classroom. Therefore, professionalism is critical for creating a productive and supportive learning atmosphere.
