“A detailed, realistic and behavioural statement of objectives is needed if we are to be able to have any reasonable expectation that our courses are going to have the effect on our students that we want them to”(Simpson, 1972).“Without an explicit set of goals and specifications, the curriculum is primarily an artistic expression of its maker”(Bloom, et al. 1971).“Clear statements of expected educational outcomes enable the teacher to plan his teaching, and the student can direct his studies and assess his progress more readily”(Wyn Pughetal. 1975)
