In O’Malley and Chamot framework of learning strategies,Oxford’s taxonomy fails to make a distinction between strategies directed at learning the L2 and those directed at using it (Ellis). The last problem is that compensation strategies are considered as a direct type of learning strategies rather than one type of production strategies,cognitive and social/affective. They grounded the study of learning strategies within the information-processing model of learning developed by Anderson. Metacognitive strategies involve consciously directing one’s efforts into the learning task. These strategies are higher order executive skills that may entail planning learning

简介：identification and classification of learning strategy. The problems are reviewed concerning the definition and classification of learning strategies and then the paper tentatively introduces Cohen’s approach to defining learning strategies in terms of prototypicality of features of learning strategies.,Cohen’s attempt to describe the prototypicality of strategies is a step forward concerning defining learning strategies. It might reflect the nature of learning strategies to a large extent because the answers to the questionnaire come from strategy experts. It is true that some problems still exist. For example,all-or-nothing feature but in terms of how far along a continuum a feature could possibly go before it stopped being descriptive of a strategy. This is an approach of defining learning strategies in terms of how prototypical the feature was. These features as follows are arranged in a descending order of agreement
