Teaching is an art. Teacher excels his arts in the class room. Classroom consists of students, teacher and blackboard. No doubt at all, “Blackboard” is the soul of a classroom. Effective teaching- learning process takes place through blackboard. Blackboard is like mirror. It takes care of all without making a distinction among gifted, brilliant, average and slow learners. Blackboard is blessing for all. Success of a teacher broadly depends on the expertise to use of blackboard in the classroom. In fact blackboard is the bridge which directly connects teacher to learners.
