【高教版】中职数学拓展模块：2.1《椭圆》优秀教学设计
本人所教的两个班级学生普遍存在着数学科基础知识较为薄弱，计算能力较差，综合能力不强，对数学学习有一定的困难。在课堂上的主体作用的体现不是太充分，但是他们能意识到自己的不足，对数学课的学习兴趣高，积极性强。 学生在学习交往上表现为个别化学习，课堂上较为依赖老师的引导。学生的群体性小组交流能力与协同讨论学习的能力不强，对学习资源和知识信息的获取、加工、处理和综合的能力较低。在教学中尽量分析细致，减少跨度较大的环节，对重要的推导过程采用板书方式逐步进行，力求让绝大多数学生接受。 1.理解椭圆标准方程的推导；掌握椭圆的标准方程；会根据条件求椭圆的标准方程，会根据椭圆的标准方程求焦点坐标. 2.通过椭圆图形的研究和标准方程的讨论，使学生掌握椭圆的几何性质，能正确地画出椭圆的图形，并了解椭圆的一些实际应用。 1.让学生经历椭圆标准方程的推导过程，进一步掌握求曲线方程的一般方法，体会数形结合等数学思想；培养学生运用类比、联想等方法提出问题. 2.培养学生运用数形结合的思想，进一步掌握利用方程研究曲线的基本方法，通过与椭圆几何性质的对比来提高学生联想、类比、归纳的能力，解决一些实际问题。 1.通过具体的情境感知研究椭圆标准方程的必要性和实际意义；体会数学的对称美、简洁美，培养学生的审美情趣，形成学习数学知识的积极态度. 2.进一步理解并掌握代数知识在解析几何运算中的作用，提高解方程组和计算能力，通过“数”研究“形”，说明“数”与“形”存在矛盾的统一体中，通过“数”的变化研究“形”的本质。帮助学生建立勇于探索创新的精神和克服困难的信心。
统编版三年级语文上第25课灰雀教学设计教案
《秋天的雨》是统编版教材三年级语文上册第八单元的一篇精读课文，课文讲述了列宁、灰雀和一个孩子之间的故事。这个故事表达了列宁善解人意，对男孩的敬重、保护以及男孩的老实和天真。通过语言和行动来揭示人物的内心世界，展现事件的开展进程，是本篇课文在表达上的主要特点。在学习时，可以对话为重点，研读课文，通过阅读人物对话，揣摩体会人物不同的心情，感受列宁爱鸟更爱孩子的情感，懂得知错就改是诚实的表现，同时产生保护鸟类等动物的环保意识。 1.会认“宁、胸”等10个生字，会写“郊、养”等13个生字。2.分角色朗读课文，读出对话的语气。3.带着问题，边默读边推敲人物的内心想法，体会列宁对男孩的尊重和呵护、男孩的诚实与天真。4.体会列宁的善解人意、循循善诱和对儿童的爱护，懂得做错事情应该改正的道理，同时教育学生要爱护动物。 1.教学重点：通过朗读对话体会列宁、小男孩心理变化的过程。2.教学难点：能带着问题，边默读边揣摩人物内心的想法。能体会列宁对男孩的尊重与呵护、男孩的诚实与天真。 2课时

二元一次方程组教案教学设计
1、问题1的设计基于学生已有的一元一次方程的知识，学生独立思考问题，同学会考虑到题中涉及到等量关系，从中抽象出一元一次方程模型；同学可能想不到用方程的方法解决，可以由组长带领进行讨论探究.2、问题2的设计为了引出二元一次方程，但由于同学的知识有限，可能有个别同学会设两个未知数，列出二元一次方程；如果没有生列二元一次方程，教师可引导学生分析题目中有两个未知量，我们可设两个未知数列方程，再次从中抽象出方程模型.根据方程特点让生给方程起名，提高学生学习兴趣.3、定义的归纳，先请同学们观察所列的方程，找出它们的共同点，并用自己的语言描述，组内交流看法；如果学生概括的不完善，请其他同学补充. 交流完善给出定义，教师规范定义.
