Listening, the most widely used language
skill, is often used in conjunction with the other skills of speaking, reading
and writing. Listening is not only a skill area in language performance, but is
also a critical means of acquiring a second language.
Assessing listening is not an easy job since it cannot be simply measured by observing student's performance. Brown stated “When you propose to assess someone’s ability in one or a combination of the four skills, you assess that person’s competence, but you observe the person’s performance” Active listening is vital tool for improving communications with others both professionally and personally.
Listening involves "bottom-up" processing that is when listeners attend to data in the incoming speech signals and "top-down" processing in which listeners utilise prior knowledge and expectations to create meaning. Both bottom-up and top-down processing are assumed to take place at various levels of cognitive organisation: phonological, grammatical, lexical and propositional.
