    人教部编版七年级下册回忆鲁迅先生(节选)教案

    《回忆鲁迅先生》(节选)是一篇典型的有较长篇幅的散文。本教学设计以点带面,长文短教,设计了这样一个问题:“作者在文中为鲁迅先生塑造了多个身份,具体有哪些?”如此化繁为简,使课堂教学脉络清晰。学生在阅读长篇幅文章时有了抓手,就可以有条理地去思考,形成系统性思维,直达教学目标。本教学设计还要求学生进行批注式阅读,直入文本。学生围绕“说说鲁迅先生身上有哪些优秀的品质让学生萧红印象深刻?”做赏析式或者评价式批注,让学生在自读这篇文章时,将无目的阅读变为有效阅读,既提高了课堂效率,也让学生真正做到潜入文字之中,通过关注文章细节来深入把握文本。本教学设计整体上以学生自主学习为主,教师适当引导。遵从“整体感知内容—局部探究—体会情感”的一般阅读规律,以读为指引,让学生在读中感知内容,在读中把握人物形象,在读中体悟情感。各环节之间环环相扣,由浅入深,层层推进。
