Which characteristic of effective teaching involves clearly communicating what action must be performed and how it must be performed?

The correct answer focuses on the characteristic of effective teaching that emphasizes the importance of clarity in communication when instructing students on how to perform specific actions. Effective teaching is anchored in the ability to articulate instructions clearly and effectively, ensuring that learners not only understand what they need to do but also how to execute the task correctly.

Motivation in teaching pertains to the ability to inspire and engage students, which is essential but does not directly relate to the mechanics of communication about actions and processes. Similarly, the desire to teach reflects a personal commitment and passion for educating others, while leadership abilities pertain to guiding and managing learners, influencing their learning environment. Subject competency, on the other hand, is crucial for understanding the material being taught, but it does not necessarily ensure that the instructor can communicate processes effectively.

Thus, the characteristic that encompasses the clear communication of actions and procedures aligns best with effective teaching, making it essential for instructors to develop this communication skill to ensure student success and understanding.
