An effective teacher's role is to facilitate learning and holistic development.
This involves creating a safe and supportive classroom environment where students feel comfortable expressing their ideas, thoughts, and doubts.
Enabling students to express themselves freely fosters critical thinking, creativity, and communication skills.
Maintaining silence (B), promoting rote learning (C), and focusing only on marks (D) are characteristics of a restrictive, teacher-centered environment that hinders true learning.
Therefore, enabling free expression is a key goal of modern, student-centered education.
