What should an instructor do in preparation for a new lesson topic?

A thorough knowledge of the topic is crucial for an instructor when preparing for a new lesson. This understanding allows the instructor to effectively communicate the information, address student questions, and relate concepts to practical applications. Having extensive knowledge enables the instructor to anticipate potential misunderstandings and prepare appropriate explanations or examples to clarify difficult points.

This foundational understanding also empowers the instructor to adapt the material to the needs and backgrounds of the students, making the learning experience more relevant and engaging. Overall, being well-prepared sets the stage for a successful lesson, as it instills confidence in the instructor and enhances the learning environment.

The other options might contribute to lesson delivery but do not emphasize the importance of the instructor's mastery of the topic, which is essential for fostering student understanding and engagement.
