英语是一门实践性、交际性很强的学科。只有把学生置身于大量有效的实践活动中去体验,才能更好地感悟语言掌握语言、运用语言。然而,纵观目前小学英语课堂,活动虽已普遍开花,却存在很多误区:有的重形式,轻目的;有的重个体活动,轻全体参与;有的重机械操练,轻真实交际……这些活动虽表面光鲜,却效率低下。如何避免这些高耗低效的行为?我认为关键之一是在活动中要做到开放有度,以达到活动的开放性与适度性的辩证统一。某教师在教学《Shopping》的对话时,为了巩固本课句型,她在教室里布置四个柜台:水果店、文具店、玩具店、服装店,每样实物都标有实价。教师先示范和一个学生表演 English is a practical, communicative subject. Only by immersing students in a large number of effective practical activities to experience, in order to better understand the language to master the language, the use of language. However, there is a lot of misunderstandings in the present primary English classroom. Although there are many erroneous forms: some are heavy forms and light ends; some are individual activities and all are light ones; some are heavy mechanical exercises and are light and real Although the activities of a bright surface, but inefficient. How to avoid these high-cost inefficient behavior? I think one of the key is to be open in the activities to achieve the dialectical unity of openness and moderation of activities. A teacher in the teaching “Shopping” dialogue, in order to consolidate the class pattern, she arranged four counter in the classroom: fruit shop, stationery store, toy store, clothing store, every kind is marked with the actual price.
