【关于梯田阅读】 以阅读的方式学习语言和获得成长,不是什么创新的理念,母语如此,外语亦如此。它是所有语言学习和人的成长共同遵循的规律。孩子的英语学习如果没有大量的阅读,就如同语文学习只局限于语文教材一样,孩子不可能获得真正的语言能力,更谈不上用这一语言去探索未知世界。没有阅读,就没有完整意义上的英语学习。 孩子的阅读经历五个不同的阶段:启蒙,听读,朗读,默读和读写,分别对应不同年龄。梯田阅读一期制作了240本(每季度增加新书),科学合理组织每日阅读计划。 不能坚持是阅读最致命的杀手,坚持每天阅读至少20分钟,是阅读对我们的最大考验。一般坚持六个月以上才有效果。 帮助我们坚持阅读的方法很多,比如固定时间,指定计划,物理化呈现孩子的进步;阅读小组等等。梯田阅读采用了科学的符合儿童心理的方式,以故事情节的发展为脉络,统领每册读物的展开;辅助以勋章,星星为激励手段,做到即刻反馈,短时长期奖励相结合。在线下实体店的小学员们已经充分验证了有效性。 此外,我们深度结合小学阶段英语课内教学。我们深知中国父母面对问题的独特性,建立了课外阅读和课内知识体系的有效连接。人教版(3种英语教材)共计967个三会词汇在我们一期240本读物中已做到98%覆盖。同时334个句型也做到了100%覆盖。在有趣完成每日阅读任务同时,有效提高课业成绩。同时。梯田阅读业已参照《中国中小学生英语分级阅读标准》(实验稿)完成等级划分。 道理通俗易懂,重要的是行动。对于不同年龄和起点的孩子,我们提供了灵活的学习方式,每天阅读1-3册,在2-6个月完成全部书目的阅读。 最后,希望我们的相遇不仅能成就孩子的英语学习,更能开启孩子爱阅读的智慧生活。让我们一起体验阅读的力量,传递阅读的力量。 【关于我们】 语言的学习,一头连着思维方式,另一头连着文化与视野。它不仅仅是孩提时代的孤立游戏,而且是一个牵涉甚广的系统工程,最终将影响一个人的价值观、思维方式、文化视野和审美能力。 梯田汇聚来自清华大学、北京外国语大学的顶级语言学专家团队,依据全球权威通行的ESL体系,并整合华东师范大学的积极教育心理学系统,为二语儿童量身定制3-8岁线下启蒙课程。 我们针对中国幼童的特点,整合英语语言学、学前教育学、婴幼儿发展心理学等各学科专业理念,结合移动互联网技术、人工智能技术,为二语孩子提供适合的启蒙教育体系。帮助孩子建立跨文化全球视野,做世界公民。 最最重要的,我们希望留下坚持不懈的恒久之心、寒暑不辍的行事习惯。既不被外部的困难所阻断,也不被内心的懈怠所诱惑。凡有恒心、风雨无阻的孩子,终将获得时间馈赠的礼物。
