What is the difference between inductive and deductive theory?

"Theory" is too broad! Let take an example for you to
understand "inductive and deductive". In grammar, for example, "inductive
grammar" is used when you give your students some various examples
related to one point of grammar, then ask your students to draw the structure and some
notes, some exceptions... In the other hand, "deductive
grammar" is applied when you give them the already made structure, some
notes, exceptions,... and let them give example based on the structure!!! And now you
can yourself answer your questions??? This looks like "inductiveness"!!!
