As a passionate learner, I believe that teaching is a practice of mutual learning. Teachers’ responsibilities have grown over the years with the expectation of keeping themselves updated and encouraging students to raise questions. In the world of higher education, research-based academics have become a trend to meet the challenges of the twenty-first century. Research-oriented higher education encourages students to explore the limits of the subject and to acquire knowledge that has long-term sustainability. With my hybrid approach to teaching methodology and research skills, I want to develop the interest in the students to attain a strong knowledge base that would help them to have successful careers.
