How Positive Feedback Can Shape A Student’s Confidence

School or college becomes a second home and safe space for students apart from their teachers. As these are the essential years for children, even a small praise like 'good job' can have a lasting impact.  

According to Psychologist Albert Bandura, the concept of self-efficacy gives a belief to the students 'I can do this', which is important for developing their own identity. This way, students also believe success is in their control.

By praising them and giving meaningful feedback, you are giving them confidence and removing the fear of being wrong.
When meaningful feedback becomes an identity, it builds confidence, and students internalise this.

Moreover, unexpected, sincere, specific praise triggers dopamine, which helps the brain remember both the skill and the feeling of 'I can do it'.
