Forced! It does not work.
A peaceful mind is the first requisite in any endeavor. The tendency of the mind is to wander. The mind has to be kept under intellectual supervision but that is possible only through inducing the right assessment of priorities. Mind reacts to the stimuli from the world, and responds accordingly, but a preoccupied mind leads to a confused response. The first priority of teacher should be to enhance mind concentration or availability to draw the attention totally and completely.
Where is the room of any doubt for the one who is convinced that the task is within his capacity This should be the essence of very education. A conducive environment must be created by the educator to build high self confidence and high self esteem within students.
Attitude makes the difference. The educator should become a source of positive attitude for the students. Louis A. Berman said "A good teacher is a master of simplification and an enemy of simplism". A educator must promote simple living but high thinking attitude. This greatly helps in intellectual development which in turn will do.
According to William Arthur Ward "The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires". An educator has to lead by example. One has to act than to lecture.
