Discipline: Education, Chemistry
As generally defined, modules are a set of components combined on a common mounting so that each component can be readily inserted into or removed from a specific place in a larger system. Thus, modular approach essentially is a programmed system of approach which integrates individual components for a given objectives, for example, identifiable topics for a given subject, or identifiable subjects for a given course. It is a programmed system because the instructional modules can be self-pacing and made adaptable to mini-courses, and yet, can be used, at will, in conventional teaching systems, 'Each module can be so constructed to make the teaching-learning activity more practical and simpler by considering only objectives and purposes for which the modules have been constructed and developed. This could cut across the three disciplines - biology, chemistry, and physics.
