What is an example of disruptive behavior caused by an instructor?

The correct answer highlights a significant issue that can affect the learning environment. When an instructor is unprepared, it can lead to a lack of structured learning, confusion among students, and a failure to cover necessary material effectively. Instructors who come to a session without adequate planning may struggle to answer student questions, provide relevant examples, or manage the class effectively. This behavior detracts from the overall educational experience and can frustrate learners, leading to disengagement and potentially diminishing the authority of the instructor.

On the other hand, being sincere, ambitious, or displaying enthusiasm are traits that typically contribute positively to the learning atmosphere. Sincerity fosters trust between instructors and students, ambition can inspire and motivate learners, and enthusiasm can engage the class and make the learning process more enjoyable. In contrast, being unprepared directly undermines the instructor's ability to facilitate effective learning.
