TABLEOFCONTENTS
MYVISIONq Engineeringeducationmustcontributetothedevelopment
of people who can face new and difficult engineeringsituationswithimaginationandcompetence.
q Meeting such situations invariably involves bothprofessional and social responsibilities. The scientificallyorientedengineeringcurriculaareessentialtoachievetheseends.
HOW AM I CONTRIBUTING TOWARDS THIS VISION? q My passion in life is simply to work towards improving the quality of technical education in India.
q I am always happy to contribute my bit towards any activity which I believe will lead to better education.
q I am interested in research, because I sincerely believe that without doing any research, one becomes obsolete quickly, and that will certainly cause the quality of teaching to suffer.
q It is next to impossible to improve the quality of education without adequate focus on research.
Short term goals i) Become effective engineering educator ii) Learn new methods to deliver and assess the subject content more effectively iii)Consultancy work iv) Conduct International Conference and workshops v) Impart quality education and make students socially responsible Long term goals i) Publication of laboratory manuals ii) Secure grants from funding agencies to carryout research iv) Apply for patents

Activities in class and assignments are very helpful in learning. As the best way is to learn through active
participation.
Through activities in class and assignments, learning was easy
and we need more such activities, assignments.
This kind of activities are making us to be more
interactive and feel responsible ..

This was a great idea for learning some core concepts of the
subject and it gave everyone a chance to add their own personal
spin on their work.
It was a very good experience. Learnt many things through trial and error which is impossible to
learn in the regular class.
Should have more of these assignments to have practical and real time knowledge of
the things we learn.
