学情分析 生活经验关联:生活环境与农业关联紧密,对农作物种植、农民劳作等场景有直观认知,容易理解农业相关话题。 英语基础水平:英语基础扎实,已掌握一定量的核心词汇和基础语法,具备初步的文本分析和词汇提取能力。对构词法有零散了解,但缺乏系统梳理,在语境中运用词汇和分析词形变化的能力有待提升。 学习特点:课堂参与积极性较高,对多媒体、情境互动等教学形式兴趣浓厚,但在英语书面和口头表达的准确性、丰富度上仍需加强。 潜在需求:渴望将英语学习与家乡农业发展结合,希望通过词汇学习解决“描述农村农业变化”的表达难题,同时期待通过多样化教学形式(如视频、互动练习)突破构词法学习的抽象性。
教学准备 教师准备: 教学素材:整理教材 P50-52 的阅读文本、练习题,筛选袁隆平与杂交水稻相关的核心信息,制作问题链课件。 多媒体资源:用即梦 AI 制作 “学生参观新型农场” 的数字人引导视频,准备 LED 种植、无土栽培等现代农场相关图片和短视频。 学习工具:设计农业主题词汇思维导图模板,准备构词法专项练习单(含同义词匹配、派生词变形、复合词辨析)。 分组道具:将学生分成 4-6 人小组,准备讨论任务卡(含城市农业相关讨论要点)。 学生准备: 预习教材 P50-52 的阅读文本,标记不认识的农业相关词汇。 回忆自身了解的农业生产方式(如家里的农田劳作、当地农场种植等),准备课堂分享。 3. 准备笔记本和笔,用于记录词汇、构词法规则及课堂生成的思维导图。

Activation and construction Activity 1: Lead in The teacher sets the scene: Li Hua, the President of the Student Union, is announcing a farm visit. Students then watch a video to learn about this modern farm. 通过创设“李华通知同学们参观新型农场”的情境,自然引出本课的核心话题与主要内容。通过多媒体视听的方式,激发学生参与兴趣和好奇心,变被动学习为主动探索。 AI 数字人情境导入:应用即梦 AI 制作 “学生会主席李华” 的数字人视频。
Activation and construction Activity 2: Review and Learn Students go through the reading passage on P50, 51 and find out words and expressions according to the questions below to acquire agriculture-related words and expressions and learn three main types of morphological processes. Students identify three main types of morphological processes through exercises on the book. Q1:Why did Yuan Longping devote his life to farmers Q2:What was the main crisis Yuan Longping wanted to tackle Task1: P52 Ex1. Replace the underlined words with the correct forms of the words from the text. Q3:How did Yuan Longping boost the output of rice (Further questions: What was the common assumption about hybrid rice before Yuan’s research What are the characteristics of hybrid crops ) Task2: P52 Ex2. Complete the sentences with the correct forms of the words from the text. Then use these words to make your own sentences. Q4:How did Yuan expand food production in China in an innovative way 1.通过遇到的问题、解决方法与事件意义等介绍一个农业专家的问题链,引导学生提取、梳理、体会作者的用词,并通过品读语言和词汇,输入农业相关的表达,加深对农业与农业科学家意义的理解。 2.在寻找表述的过程中,通过教师对于三种构词法的举例介绍,帮助学生在真实语境中初步了解构词法,构建结构化的词汇体系,深化对词汇间关系的理解。 3.通过文本中的分辨词义、分辨构词法、造句等多种练习,实现词汇复现,并帮助学生巩固构词法的概念,在活动中对词汇深度加工,并初步运用词汇在语境中选行表述。 在单元主题引领下通过问题链学习、梳理、分类单元词汇。 2.在语境中学习词汇、学习构词法、构建单元主题词汇网络。
Activation and construction Activity 3: Summary Students construct a mind map based on agriculture-related words and expressions learnt in this class. Q5: From what aspects can we describe a farm with a modern farming method Create a mind map and find more aspects. 通过构建新型农场相关表述的思维导图,培养学生自主学习能力,内化所学知识,并以可视化模型整理词汇和短语引导学生厘清词汇的意义,建立话题下多个词汇的联系,为后续灵活运用相关词汇搭建手脚架。 构建新型农场相关表述的思维导图
Practice Activity4: Practice Students complete agriculture-themed passage with agriculture-related words and expressions. Task3: P52 plete the news report below with the correct forms of the words and phrases in the box. 通过在主题话境中的 词汇复现、语篇填练 习,帮助学生巩固所学的语言知识,并为后续的语言输出提供相关背景信息。 在语篇中内化所学词汇。
Application Activity 5: Application Students apply agriculture-related words and expressions to describing a farm with a modern farming method and express their opinions on importance and meaning of agriculture. Q6: Describe a farm with a modern farming method according to the introduction and pictures.(Use words and expressions learnt in this class, such as output, consumption, tackle, vision, conventional, etc.) 通过获取新型农场的背景信息及图片,引导学生将阅读语篇中所学的知识迁移到同一个主题语境下的真实情境中,并在运用过程中加强对所学农业相关主题的表达,提高语言表达能力和思维品质,表达真情实感,增强情感体验。 应用环节,使用豆包AI生成现代农场的图片,帮助学生了解现代新型农场。
Activity 6: Discussion Q7: Do you think urban farming (like the tunnel farm in the news report) can become a reality in most cities Why or why not 通过运用所学词汇,引导学生加深对新型农场的了解。通过讨论引导学生批判性思考农业创新问题,培养负责任的态度与价值观。 从学词汇到培养思维,从知识到素养,落实育人目标。

板书设计/课堂小结 课堂小结: 词汇掌握:本节课共学习 8 个农业主题核心词汇,能区分动词、名词、形容词三类词性,理解并运用 “commit to farming”“tackle the crisis” 等搭配; 构词法运用:掌握同义词替换、派生词变形、复合词构成三种规则,能分析 “creation”“shortage” 等词的构词方式,辅助词汇记忆; 话题理解:通过袁隆平事迹和现代农场案例,理解农业创新的重要性,能运用所学词汇描述农业场景、表达对农业发展的观点; 4. 后续建议:课后可结合家乡农业情况(如水稻种植),用所学词汇记录观察,提升词汇运用熟练度。
教学反思 亮点与成效: 1.情境导入贴合学生生活背景,农村学生对农业话题熟悉,配合 AI 数字人视频,课堂参与度较高,多数学生能主动参与词汇提取和讨论。 2.构词法教学结合文本实例和练习,由浅入深,成绩中上学生能快速掌握规则,在后续练习中准确率达到 80% 以上。 3.小组讨论和思维导图环节,有效培养了学生的合作能力和知识梳理能力,部分小组的成果展示逻辑清晰、词汇运用丰富。 不足与改进: 1.部分学生在派生词变形时仍存在词性混淆问题,后续需增加针对性专项练习,结合 AI 工具设计个性化错题巩固。 2.口语表达环节,少数学生因担心出错不敢主动发言,需优化 AI 测评工具的反馈方式,增加鼓励性评价,同时设计小组内轮流发言机制,降低表达压力。 未来优化方向: 1.结合农村学生的生活体验,增加“描述家乡农业变化”的拓展任务,让词汇运用更贴近实际。 2.优化问题链设计,增加分层问题,满足不同水平学生的需求,让成绩中上的学生有更多拓展提升的空间。 3.加强课后反馈,通过 AI 工具跟踪学生作业中的词汇运用情况,针对性进行答疑和补充练习。
