What does professional ethics require regarding teachers' online behavior?

• A. It prohibits any use of social media.
• B. It allows posting unverified gossip in public forums.
• C. It only applies to student interactions offline.
• D. It requires responsible use of social media and maintaining professional boundaries.

Answer: (D)

Professional ethics for teachers' online behavior means using online tools in a way that reflects professionalism and protects students and the school community. A teacher’s online presence can influence trust, the learning environment, and safety, so responsible use of social media and clear professional boundaries are required. This is why the best choice emphasizes both responsible online conduct and maintaining appropriate boundaries. The other options miss the mark: banning all social media is impractical and unnecessary; posting unverified gossip is unethical and harmful; and ethics apply to online interactions as well as offline, since privacy, respect, and professionalism extend to digital communications.
