  • 《边城》说课稿2021-2022学年统编版高中语文选择性必修下册

    (重点突破一)1、分析环境描写 探讨边城的景美?(重点突破二)2、分析人物形象 探讨边城的人性美和人情美?至此,以三要素为切入口,文章的重点已分析完毕,下一个步骤就是突破难点。第二课时首先回顾上节课所讲的内容 (5分钟)(四)(难点突破)探究主题我设计了这样两个问题:1、小说表达了什么样的主题?(5分钟)2、有人说:《边城》从头到尾都隐藏着一种淡淡的愁绪,说说你的认识?从这篇小说中你可以看出沈从文先生的哪些显著的写作特点?(15分钟)这是两个定向设问的探究题,目的性很明确,就是为了突破难点,探究文章主旨。为了帮助学生理解文章的主旨,我用多媒体向学生 介绍《边城》的写作背景,给出“边城”的解题。对于第一个题,学生的答案可能会有很多种,比如“美”“爱”“纯”“和谐”“自然”等等,只要能基本概括,理由充足即可。

  • 《氓》说课稿-2020-2021学年统编版高中语文选择性必修下册

    “将子无怒”急于成婚,至于发怒,表现出急躁的性格特征;“二三其德”,又表现出他品德的败坏;“言既遂矣,至于暴矣”婚后的暴躁,婚前的热烈,婚后的离弃,两相对照,则揭示了他的虚伪自私。总之,氓是个性情狂暴、违背诺言、始爱终弃、不负责任、自私的负心汉。设计意图:用流行语概念引导学生去解读不同作品中的人物,培养学生比较分析的能力。3、探究《氓》中造成女子婚姻悲剧和痛苦的原因有哪些?个人原因:①氓的三心二意,不负责任。文中说“女也不爽,士贰其行”,女子怨恨的正是自己甘心贫困,辛苦操劳,多年如一日,但是最终还是被丈夫遗弃。②女子在经济上政治上处于附属地位。她生活天地狭小,生活的幸福与否全寄托在丈夫身上。如果遇上个对感情对家庭不负责任的丈夫,那她的悲剧是不可避免的。③性格悲剧。在男权社会中,女子在婚前行为草率,她与氓的恋爱缺乏牢固的思想基础,对氓的人品认识不足,认人不清导致的悲剧。社会的原因:

  • 《项脊轩志》说课稿 2021-2022学年统编版高中语文选择性必修下册

    1.诵读法。鉴赏文学作品应在反复诵读的基础上进行,在诵读的过程中,学生声情并茂,有利于体会作者所表达的情感。2.情景教学法。借助多媒体辅助教学,营造良好的学习氛围,激发学生的学习兴趣。3.点拨、讨论法。学生对老师设置的思考题以及自己不理解的地方进行讨论,得出比较准确的答案,老师在适当的时候给以点拨。学法:“新课标”旨在建立“自主—合作—探究”的学习方式,课堂上学生“学会学习”比“学会什么”更为重要,因此我设计如下学法:1、自主学习法:学生是学习的主体,让学生带着问题读书,目的明确,学生边读边思考问题,并简单分析散文的结构和作者所表达的情感。2、合作探究法:学生以小组合作的形式,选择一个自己感受最深的语段以及文中的重点词语去探讨作者是怎样表达他的悲痛之情的,然后交流各自的体会。

  • 古诗词诵读《将进酒》说课稿2021-2022学年高中语文统编版选择性必修上册

    一、说教材选修课是在必修课程基础上的拓展与提高,它力争促进学生各自特长和个性的形成。我们在必修部分已经学习了李白的一首古风《蜀道难》,学生对李白其人及其诗风已有了一定的了解。本单元的任务是“因声求气,吟咏诗韵”,它要求我们通过对古典诗歌声律特点的把握,学习有感情地吟咏,诵读作品,并深入地了解诗歌的感情。《将进酒》一诗时而奔放,时而深沉,感情大起大落变化明显,学生容易进入吟咏和体会情感的体验阅读中。二、说教法学法现代语文观念中提倡语文教学要多读,要培养学生的语感,特别是对一些优秀的古诗文。可见在学习古代诗文的过程中,诵读是非常重要的,有助于加深学生对课文思想内容的理解。可以在朗读中理解诗文的内容,所谓“读书百遍其义自见”,在反复的朗读中可以慢慢体会诗人所要表达的思想感情,因此本堂课我采取以诵读为线索,完成对诗歌思想内容的理性思考。

    一、温故导入好的导入未成曲调先有情,可以取得事半功信的教学效果。对于本节课我以温故知新的方式导入,以苏轼的《赤壁赋》和《念奴娇》引导学生感受苏轼的豪放和阔达,从学生熟悉领域出发,引导学生探究他内心深处的“柔情似水”,感受他的“十年生死”之梦。二、诵读感知(亮点一)《语文课程标准》中建议“教师要充分关注学生阅读需求的多样性,阅读心理的独特性”。所以在本环节我将综合运用听、读、问、答四种方式教学。首先通过多媒体听读,激发学生学习兴趣,直观感受苏轼的痛彻心扉和伤心欲绝。其次指定学生诵读,并在诵读之后,由学生点评,加深学生对于断句、轻重、快慢的理解,进一步感受本词的凄苦哀怨。最后配乐读,利用凄清的音乐引导学生通过自己的诵读来表现诗中所蕴含的真挚之感。设计意图:通过多种阅读方法,反复阅读本词,引导学生由浅入深的理解本词的思想内容和艺术风格,初步感受作者对妻子的挚爱之情和他的痛彻心扉,加深学生对文章的理解。

  • 《一个消逝了的山村》说课稿 2021—2022学年统编版高中语文选择性必修下册

    这几段内容传达出的是“要敬畏生命,尊重生命;更要敬畏大自然,尊重大自然,爱护大自然”的主旨内涵,因此让学生通过自由朗读的方式,再次体会冯至对这个消逝了的山村的细致的美好的描绘,感悟冯至传达出的对生命,对自然的理解和思考。5.最后一个自然段的解读依然是交给学生,先齐读课文,再让学生自主分享自己的体会或疑惑。但在这一环节我也设计了两个我认为必须解答的两个问题,一是怎么理解“在风雨如晦的时刻”;二是“意味不尽的关联”是指什么。我认为这两个问题一个涉及到写作背景,一个涉及到对全文主旨的一个整体把握,能够进一步帮助学生理解散文的深刻内涵和主旨,让学生有意识的在阅读散文过程中通过背景知识进行理解。既尊重学生的个性化解读,又能够让学生有意义学习,完成预设的教学目标。如果学生没有提到这两处,那我就需要做出补充。
