Dr. Nisha Velayudhan is working as an Assistant Professor Incharge, Department of Zoology, K.V. Pendharkar College (Autonomous), Dombivli. She has been teaching for the past 8 years. During these years of teaching she has realised the fact that teaching is not the same every day, it changes with the student’s interest and understanding, teachers’ dedication, learners’ intuitiveness and most importantly curiosity in both the student as well as the teacher. Writing a book was a new stage for exploring new possibilities of learning for her to express her curiosity about the subject and present her viewpoint.
