It is debatable whether it is appropriate for teachers to be harsh with students in order to teach them effectively. While some contend that using harsh discipline is vital to inspire kids and help them reach their full potential, others counter that doing so can be harmful to a kid's self-esteem and emotional health.

There is a difference between being strict and being harsh. A strict teacher sets high expectations and demands discipline, but also provides support and guidance to help students meet those expectations. In contrast, a harsh teacher may belittle and demean their students, which can lead to feelings of shame, anxiety, and a lack of self-confidence.

According to research, encouragement and positive reinforcement work better than harsh criticism to foster academic success and boost self-esteem. Teachers' encouragement and support have been shown to improve academic performance and increase students' enthusiasm for learning.

Harshness can also create an unpleasant and unwelcoming learning environment, which can lead to disengagement and a lack of motivation in students. In contrast, a positive and nurturing learning environment can encourage students to take risks, explore new ideas, and grow as individuals.

In conclusion, while teachers need to set high expectations and demand discipline, being harsh is not an effective way to teach children efficiently. Instead, positive reinforcement, encouragement, and support can help children reach their full potential and build self-esteem. Teachers should strive to create a positive and nurturing learning environment that encourages students to grow, learn, and succeed.
