Teaching methods

Dear Friends,
Well and wish to hear the same.
How many of you saw the Hindi movie Named "3 Idiot" It is very interesting and i have learned that the students participation is required in each class.
i am trying to do so. I am Happy with your interaction in the class
How many of u are really comfortable in my class and my teaching methods ?
I feel that the still my method of teaching is so conventional.
so suggest me something to have a new way of learning apart from use of LCD projector for PPT.
Those who are not watched the movie kindly watch once
bye
