Which of the following is NOT one of the roles of a teacher?

The role of an observer is typically understood as a crucial aspect of teaching, focusing on watching and assessing student behaviors, interactions, and learning styles to inform instructional decisions. This role allows teachers to gather insights into student engagement and learning progress, which can significantly enhance their teaching practices and support individual student needs.

In contrast, the roles of problem solver, disciplinarian, and facilitator are essential components of a teacher's responsibilities. A teacher as a problem solver addresses challenges that arise in the classroom, whether they relate to student learning or interpersonal dynamics. As a disciplinarian, a teacher guides and enforces classroom rules and expectations to create a safe and conducive learning environment. Moreover, serving as a facilitator, a teacher encourages student participation and promotes active learning, helping students take ownership of their education. Ultimately, these roles contribute holistically to the educational experience, whereas being an observer is more about assessment and monitoring rather than an active role in teaching and learning.
