There are two important teaching aspects in any kind of education, feedback and reflection. Though many of the concerned professionals don’t bother about feedback. Generally, engineering education does not appreciate the role of feedback as a fundamental engineering teaching tool and loose many feasible opportunities for employing this tool. In this paper, the author discusses different issues and the importance of these methodologies in engineering education. The intervention has been used in the case of one small group consisting of thirty students (postgraduate) and another large group of strength ninety undergraduate students. The subject for UG and PG students was Power Electronics and Advanced Power Electronics. To analyze the effect and improve the understanding of concerned students, fifteen minutes in class feedback is taken based on the material taught to both groups of students. The results are presented in the form of tables and graphs. These intervention results are analyzed to improve the course delivery.
