Teaching Philosophy

Teaching is a form of communication majorly aimed at effectively transferring knowledge to students. A teacher needs to be well prepared, knows his audience, be passionate about teaching, develop students’ interest in the subject and creates an enriching learning environment. I have always been very concerned about teaching with quality and excellence. That is why; I spend significant time preparing every lecture, even if I have delivered it before. I utilize student centred approach for teaching which enables me to identify and address the issues faced by students in my lectures. I am comfortable in using many learning tools e.g., Kahoot, Mentimeter etc. in my lectures to enhance student engagement. I use both formative and summative assessment methods to assess the learning of students. I try to have an interactive session with my students and encourage them to ask questions. I believe in learning through group discussions which create a very positive environment where students can discuss and learn from each other. I mark my assessments and announce results within the time frame and provide with detailed feedback on submitted work using clear and concise language.
