well, it is more difficult to teach large classes because we have to be allert of the circunstances arround the classroom and how our students learn in every particular way, because we have to active, motivate

and we have to deal with every behavior and mood of the students and the environment of the classroom.

but we have to remember that we as teacher have to be a facilitator, the person who creates the atmosphere and who involve students by giving the materials, tools, and preparing for real lifes' situation.
