Unit 4 Lesson 12 Healthy Bones教案-公开课-优质课(北师大版八上精品)
八年级英语北师大版上册Unit4Lesson12HealthyBones(第二课时)优秀教学案例
例如，在课程结束后，我可以让学生撰写一篇关于本节课学习的反思，总结自己在知识掌握、技能提高、情感态度等方面的收获和不足，以便在今后的学习中进行改进。同时，我还会根据学生的课堂表现、作业完成情况等，给予相应的评价和反馈，以激励学生的学习积极性。
此外，我还可以运用多媒体教学手段，如图片、视频等，展示骨骼健康问题的实例，帮助学生更好地理解和记忆相关知识。（二 Nhomakorabea问题导向
问题导向教学法是一种以问题为驱动的教学方法，通过问题的提出和解决，引导学生主动探索和学习。在本节课中，我将设计一系列问题，引导学生思考骨骼健康的重要性以及如何保持健康的骨骼。
例如，在讲解骨骼的种类和功能时，我可以提出问题：“骨骼对人体的作用是什么？不同种类的骨骼有哪些功能？”让学生通过讨论和思考，得出答案。
在评价方面，我将采用形成性评价和终结性评价相结合的方式，以学生的课堂参与度、口语表达能力和作业完成情况为主要评价标准，以期达到全面、客观、公正的评价。
二、教学目标
（一）知识与技能
本节课的主要内容是关于骨骼健康的重要性以及如何保持健康的骨骼。在知识方面，我希望学生能够掌握以下内容：
1.能够正确地使用相关的英语词汇和句子来描述骨骼的种类、功能和保护方法。
（五）作业小结
在课程的最后，我会布置一个与本节课内容相关的作业。这个作业可以是写一篇关于如何保持健康骨骼的小短文，或者设计一个关于骨骼健康的海报。
通过以上教学内容与过程的设计，我希望能够激发学生的学习兴趣，提高他们的学习积极性和口语表达能力，使他们能够更好地理解和掌握骨骼健康的重要性和保持健康骨骼的方法。
Unit 4 Healthy Living—12 Healthy Bones 精品导学案
第一课时(学案)First Period Read paragraph 3-5 and finish the table.第二课时Second Period教学目标在本课学习结束时，学生能够：1.在语境中体会、发现、归纳由although、but、because、so引导的状语从句的用法和表意功能；2.运用although、but、because、so引导的状语从句给身边的老师和同学提出合理的健康建议。
教学过程本课教学反思本节课主要采用过程教案法训练学生的听说读写。
过程教案法的理论基础是交际理论，认为写作的过程实质上是一种群体间的交际活动，而不是写作者的个人行为。
它包括写前阶段，写作阶段和写后修改编辑阶段。
在此过程中，教师是教练，及时给予学生指导，更正其错误，帮助学生完成写作各阶段任务。
课堂是写作车间, 学生与教师, 学生与学生彼此交流, 提出反馈或修改意见, 学生不断进行写作, 修改和再写作。
在应用过程教案法对学生进行写作训练时, 学生从没有想法到有想法, 从不会构思到会构思, 从不会修改到会修改, 这一过程有利于培养学生的写作能力和自主学习能力。
学生由于能得到教师的及时帮助和指导，所以，即使是英语基础薄弱的同学，也能在这样的环境下，写出较好的作文来，从而提高了学生写作兴趣，增强了写作的自信心。
这个话题很容易引起学生的共鸣，比较贴近生活，能激发学生的兴趣, 在教授知识的同时，应注意将本单元情感目标融入其中，即保持乐观积极的生活态度，同时要珍惜生活的点点滴滴。
在教授语法时，应注重通过例句的讲解让语法概念深入人心，因直接引语和间接引语的概念相当于一个简单的定语从句，一个清晰的脉络能为后续学习打下基础。
此教案设计为一个课时，主要将安妮的处境以及她的精神做一个简要概括，下一个课时则对语法知识进行讲解。
在此教案过程中，应注重培养学生的自学能力，通过辅导学生掌握一套科学的学习方法，才能使学生的学习积极性进一步提高。
