教学目标
1. 语言能力目标: 新课标明确提出,语言能力除了包括听、说、读、写之外,要重视看(Viewing)的能力培养。通过本课的学习,学生可以习得关于火星探索主题的词汇、短语、句子,获取视频传达的信息,并能够自主进行加工、运用这些语料,用于表达自己的观点。 学习能力目标: 通过本课的学习,学生能够在“看(Viewing)”方面得到技巧的提升,选择恰当的策略与方法,学会通过 “听”和 “看”去捕捉视频里的细节信息和主题意义;同时通过视频配音活动进一步拓展自己的听、说、看的能力。 文化意识目标: 通过本节Video time的学习,学生能够进一步对火星相关知识得以了解,坚定人类不懈追求火星探索的决心,理性看待太空探索对人类发展的深远意义,树立正确的科学观和人生观。 思维品质目标: 在本课堂活动中,学生通过看前预测、判断正误等低阶性教学活动,培养自我逻辑思维能力;在排序活动和总结概括活动中,培养学生的逻辑关系梳理能力;在采访活动和课后配音活动中,学生理性表达自己语言学习观点的能力和学习迁移能力得以加强。在整个课堂活动中,通过视频观看和教师提问等活动,逐步养成深度思考的习惯。
教学内容
教学重点: 帮助学生习得关于火星探索主题的词汇、短语、句子,并能够加以应用。 指导学生通过观看视频、获取视频里关于火星的的细节信息和主题词并归纳整合视频内容。 教学难点: (1)学生对视频内容和细节进行深度挖掘,在理解火星探索具体步骤的同时去感受和思索探索过程的不易和人类的不懈努力,从而逐步形成深度思考的习惯和模式。 (2)学生深刻分析视频涵括的信息,找准火星探索的价值和意义,用以指导自己的学习和生活。
教学过程
Stage One BEFORE WATCHING Step 1 Warming up Teacher (T) : 1. Greet the students and show the objectives to students. Show students a piece of news on China’s newly results of Mars exploration. Students (S): 1. Greet the teacher and read the news. 2. Know today’s objectives. 3. Get to be interested in exploring Mars. 设计意图: 基于英语学习活动观和学科核心素养,开门见山地明确本课三维目标。通过新闻图片和教师解释激趣,了解本课为Space Exploration话题的延伸,从而迅速投入到整节课中来。 Step 2 A quiz on Mars T: 1. Lead students to participate in the little quiz. 2. Encourage students to be active, cooperative and productive. S: 1. Activate some basic knowledge on Mars. 2. Predict what today’s video topic is. Three questions in the quiz: 1.What do you know about Mars 2. How do people explore Mars 3. What parts does the Mars probe consist of 设计意图: 通过提问启发学生,开展“头脑风暴”,使学生理解关于火星的一些必要知识,激活其背景知识,预判接下来的视频内容,并为理解视频内容做好一些表达和知识储备。 Step 3 Useful Expressions T: 1.Introduce some knowledge of Mar probe. 2.Give the students some phrases and explanations on Mars and Mars exploration. S:Guess and get to know these phrases and expressions by themselves, try to keep all of them in mind. Expressions: the orbiter 轨道器 the lander 着陆器 the rover巡游车 设计意图:介绍火星探测器的组成部分,帮助学生提前预判视频内容,迅速习得一些常用的表达方式和词汇。学生可以通过词汇拼读规则以及教师的教授,为之后的看懂和听懂视频内容,获取信息做准备。 Stage Two WHILE WATCHING Step 1 Watch video part 1 (00:00--02:28) T:1.Lead students to watch video part one,learn some detailed information on Mars. 2.Give students some tips when they meet problems. S: 1.Watch this short video and find the details. 2.Use the details to check their answers to “T ”or “ F” questions. The “ T ” or “ F ” questions are as follows: 1. Mars is the fourth planet from the Sun and the smallest planet in the solar system. 2. It is one of the few planets that we can see with the naked eye. 3. Like Earth, Mars has volcanoes, valleys, polar ice caps, seasons, and weather. 4. Olympus Mons, the largest volcano on Mars, is about twice as high as Mount Qomolangma. 设计意图:在阅读 “T” or “F” questions的时候,学生已经对于答案有所预测,在老师的指导下观看视频第一部分的时候,学生一边观看,一边判断自己之前的答案是否正确,从而提高在“看”媒体传播信息时,提高获取关键细节信息的能力。 Step 2 Watch video part 2 (02:29---05:20) T: With the help of part one and what they have got in before watching, the teacher helps students to read events in task 2. (put them in the correct order) S: 1.Students read events in task two, and watch the video. 2.Discuss with desk mates to better their answers. The correct order is: 1. The probe enters the Earth-Mars transfer orbit. 2. The probe separates from the launch vehicle. 3. The space-to-ground communications link is created. 4. Controllers on Earth guide the probe into the orbit around Mars. 5. The orbiter and the lander separate. 6. The lander discards the protective shield and the parachute. 7. The lander lands on the surface of Mars. 8. The rover transmits data back to Earth and receives orders from Earth. 9. The rover begins to explore the surface of Mars. 设计意图:学生通过小组合作和合作探究的方式,判断火星探测与对接的正确顺序,从而理解火箭发射升空到登录火星的完整过程,并进一步认知中国在这方面不畏艰险所取得的巨大成就。 Step 3 Summary of the video T: 1. Show students a chart to summarize the content of the video. 2. Encourage students to review what they have watched in video part 1 and part 2. S: 1.
