I tend to start exploring anything in science from its history or evolution, as we call it in Biology. The depth to which I have to go in explaining or helping in the completion of project is decided by the level at which my student is or the aptitude shown by him/her. The sources of information are always shared so that students are not 'spoon-fed' but take interaction with me as a learning experience. I too learn from my students and continuously try to improve on my methods.
