1.1 Background of the Study
Every instructional activity involves communication. Language is a meaningful medium of sending a message to a receiver. The message may be ideas, feelings, desires, fears, joy or sadness. Language in general terms, can be an instinctive (as in animals) or a non-instinctive (as in human beings) medium of communication. The human language manifests itself primarily in speech. The written form of human language is a later development in the evolution of man. To communicate through language we have to belong to a particular speech community whose members understand the vocal noise produced as speech or the graphic representation of the vocal noise. Speech community here does not mean an ethnic group, village, town or a people. It only means speakers of a given human language, Gimson (1976).
