Among the great teachers I have trained I remember many who knew how to scold without losing their students’ love and trust. Predictability in a teacher’s behaviour is important, advised the late American educator John Holt Dr. Krishna Kumar is former director of NCERT and former professor of education at Delhi University One of the four teachers I have kept in touch with passed away last month (November) in his late eighties. The others taught me at college or later, but Kapil Dev Tailang was the only one left from my school days. Before he was assigned to my school, he had come in for a few days when the regular teacher was on leave. The difference between the two was stark, and not because the regular teacher was not good. What made Kapil Dev Sir’s classes an unusual experience was that he did not scold. Decades later, I still find this strange. Some of the boys in my class strived to irritate him, but never succeeded in provoking a reprimand. His style did not include harsh or loud words. He was a language teacher, and Hindi was his language. He took care not to pollute it in our minds with uncouth usage. His distinction as a teacher shone in moments when he was under stress.

Among the teachers I have trained, I remember many who knew how to scold without losing their students’ trust and love. Predictability in a teacher’s behaviour is important, advised the highly respected American educator John Holt (1923-85) who had deep personal insight into children’s minds and the flaws of America’s school system. One of his most famous books, How Children Fail (1964) could well be re-titled When Teachers Fail. It is not the scolding, but the unpredictability of a teacher’s anger that frightens children and makes them distrustful. With Kapil Dev Sir, you knew there was no need to feel fearful of him. He was a peace extremist. When boys tried to annoy him, he smiled at them. Most of the time when he was teaching, no one felt like taking advantage of his calm disposition. I recall, when some boys persisted in aggravating him, Kapil Dev Sir left the class, laughing. Long after his retirement, he maintained this capability to laugh at irritants. “My laughter keeps me in good health,” he would say. His subject had low status in those times, even in a government school. There were no coaching classes in our town, but even then, science and math were regarded as critical to ultimate success, and teachers of these subjects exuded an air of superiority because…
