Which of the following behaviors does NOT foster effective instructor/student interaction?

Using profanity or obscenity clearly does not foster effective instructor/student interaction because it creates a hostile learning environment and undermines the respect and professionalism necessary for effective communication. Instructors are responsible for modeling appropriate behavior and language, serving as role models for students. This type of language can alienate students, inhibit their willingness to engage, and detract from a safe and productive classroom atmosphere.

In contrast, providing constructive feedback encourages a positive learning experience by promoting student growth and understanding. It guides students on how to improve their skills or knowledge. Additionally, avoiding talking over students' heads is important for ensuring that all students grasp the material being taught, as it fosters an inclusive environment where learners feel valued and understood. Practicing patience is critical as it helps instructors deal with questions and misunderstandings effectively, which further encourages student participation and confidence.
