当前语文教学的学理性,应以母语语言能力的强化为意图,以元语言能力的培养为高一层级的目标。元语言能力属于一种元语言意识行为,体现了主体对语音、单词、句法、语用等要素的主动控制。在元语言能力对言语行为的监控反思过程中,伴随着元语知识向以语感为核心的一般语言能力的转化。“学得”机制并不仅仅体现为克拉申的语言“监控”功能,它还是形成、强化语言能力尤其是元语言能力的重要途径。 At present, the rationality of Chinese teaching should be based on the reinforcement of the mother tongue’s language ability and the goal of being one level higher with the training of the meta-linguistic ability. Metalanguage competence belongs to a kind of metacognitive consciousness, which embodies the initiative control of the subject on phonetics, words, syntax and pragmatics. In the process of monitoring and reflection on verbal behavior by metacognitive ability, it is accompanied by the transformation of metacognitive knowledge into general linguistic competence with linguistic sense as the core. “Learning ” mechanism does not only reflect Krashen’s language “monitoring ” function, it is also an important way to form and strengthen the language ability, especially the metalanguage ability.
