An effective instructor should adhere to which of these guidelines?

An effective instructor should indeed strive to always accept a person's answer and talk to the entire group. This approach fosters an inclusive learning environment, encouraging participation from all students rather than singling out individuals or specific sections of the group. By acknowledging each person's contributions, the instructor validates the speaker's input while also promoting a sense of community and shared learning. Engaging the whole group allows for diverse perspectives to be shared, enhances interactive discussions, and ensures that all students feel valued and involved in the learning process.

In contrast, addressing questions only from the front row would limit engagement with the entire audience and could make students in other areas feel marginalized. Ignoring non-verbal cues dismisses crucial feedback that can enhance teaching effectiveness, as non-verbal signals often indicate student understanding or confusion. Focusing solely on the individual speaking can detract from group dynamics and overall class participation, as it does not encourage a collaborative learning atmosphere.
