Robin (1975) defined the learning strategies as “the techniques or devices that a learner may use to acquire knowledge”. In her later research, she identified two kinds of learning strategies: those that contribute directly to learning, and those that contribute indirectly to learning. O’Malley (1985) identified learning strategies as being”operations or steps used by a learner that will facilitate the acquisition, storage,retrieval or use of information”,which was originally used by Rigney (1978).
