In this paper, an effort to involve students of undergraduate Electronics (Instrumentation & Control) engineering has been made. The learning and understanding of any undergraduate student is very important as they are going to implement the knowledge attained during their four-year engineering programme in their professional career and to achieve heights. The conventional methodologies of teaching need some creative and innovative ways of making them understand whatever course is being taught to them. In the course of ‘Digital Signal Processing and Applications’ a sample group of 25 students was considered as a case study to apply the innovative technique of sharing the knowledge gained through use of available resources like internet, books, research articles, peer learning and classroom teaching. The methodology of think pair and share through which they help each other to learn and understand has shown certain innovations. Think pair and share technique has shown an improvement in attendance and performance in end semester examination as well. In this work, it is proved that innovative ways of teaching, adopted by teacher in the classroom, increases the interest of students in learning as well.
