Which of the following is NOT considered a teaching style?

The correct response identifies "Observer" as not being categorized as a teaching style. In the context of educational methodologies, teaching styles refer to the various approaches educators take to engage and impart knowledge to their students. The styles listed—Authority, Delegator, and Facilitator—each denote active roles that instructors adopt to enhance learning experiences.

The Authority style involves a more traditional approach where the instructor is the primary source of knowledge, directing the learning process and maintaining control.

The Delegator style empowers students by allowing them to take responsibility for their own learning while the instructor serves as a mentor or guide, facilitating the process without direct intervention.

The Facilitator style promotes a more interactive and student-centered approach, encouraging collaboration and dialogue between students and instructors to foster a deeper understanding of concepts.

In contrast, the Observer role is more passive and does not actively contribute to the teaching process. An observer may witness the learning environment without engaging directly in the instructional activities or guiding student learning, which is why it is not recognized as a valid teaching style.
