本节课主要教授的是外研版（2019）必修第三册 Unit 3 The world of Science Developing ideas一课程。本单元的主题语境是“人与社会”，涉及的主题语境内容是科技发展和科学精神。Developing ideas板块课文的语篇类型为论说文。介绍了人们对Franklin著名的风筝实验真实性的怀疑和求证,学生将通过本篇课文的学习了解科学家的故事、学习科学家的求真精神。
二. 学情分析：
学生是高二年级的学生，之前因为疫情原因加上学生自己的实际水平的原因，所以我们高二才开始必修第三册的学习。我们的学生英语水平有限，而且对科学领域的知识了解相对较少。但是他们对新知识充满好奇，希望能够通过课堂学习，更好地了解科学的定义、学习科学家追求真理的精神，并能把这种精神运用到以后的英语学习中。

教学反思：
本节课的教学目标基本完成，学生通过课堂讲解和讨论，学生对Franklin的实验内容有了初步的了解和认识，也了解了科学家们为了追求真理，不断思考和探索的精神。然而，在教学过程中，我也发现了一些问题。
首先，我在课堂中的互动和引导不够充分。由于时间有限，我倾向于给出答案并解释，而不是通过提问引导学生自己思考。
其次，我需要更多地关注学生的学习进步和反馈。在课堂结束前，我应该留出时间给学生提问和反馈，了解他们的疑惑和困难，并给予及时的指导和帮助。
再次，自己的备课不够充分，在 ppt制作中出现了两处错误，一个是把author 写成了auther , 还有一处是把believing 写成了believeing 。
最后，自己的英语发音和综合表达能力还需进一步提高。
