Unit 8 Discoveries
Lesson 24 An Experiment Report
一、教材内容分析
本课为第8单元第三课，是一节阅读课。本课是一篇实验报告，主要内容为种植马铃薯的步骤和经过。文本包括：实验准备，实验过程观察记录，实验的收获和感想三部分内容。本课还着重培养学生记笔记的学习策略。本课只有九个单词，没有明显的语法，但是通过阅读使学生了解成功种植植物需要的元素，认识到成功做事需要耐心和努力。本课为下一课的写作输出打下了语言和精神基础。
二、课时分配
本节课分为两课时，第一课时重在阅读。首先通过粗读了解文章的三部分主要内容，即：实验准备，实验过程观察记录，实验的收获和感想。然后采用分段阅读法，通过细读种植过程部分引导学生学习、实践记笔记的策略。在此环节为了引导学生后面的情感升华，我在表格上加了每一天的情感，使学生关注reporters’ feeling。最后通过阅读文本最后一部分回答问题，引起学生更深的理解和思考,并结合实验报告谈论这种实践活动是否对像reporter这样的六岁孩子们有益，使学生利用本课内容进行输出。
第二课时重在内化和运用。首先回顾文本内容, 然后让学生从实验中选择一天进行具体细致地描述。接着阅读一份新的实验报告，利用make notes 策略填写表格，提升学生应用阅读策略的意识和能力。最后小组合作回忆他们曾经做过的一个实验谈论并写出实验报告。
