Textbook analysis
Footprints on the Moon is a text in Unit 4 of the first volume of the seventh grade of the new textbook. From the perspective of textbook compilation, this unit embodies the scientific exploration of nature. Its main purpose is to enrich students' scientific knowledge, improve students' ability to read modern scientific articles and collect screening information, stimulate students' thirst for knowledge, cultivate students' scientific spirit and explore the unknown world. This text describes the greatest scientific expedition of the 20th century-landing on the moon. The author recorded the whole process of man's first landing on the moon in plain language. The four parts described in this paper are clear and smooth: preparation, liftoff, landing on the moon and going home. Finally, Armstrong said, "This step is a small step for a person; It is a huge leap for the whole mankind, leaving readers with endless aftertaste, from which we can realize the great significance of human landing on the moon. The theme itself can arouse students' rich association and enough interest, and this lesson is closely related to the comprehensive study of this unit-exploring the mystery of the moon. The information about the moon is very rich, and both natural and human phenomena are worth exploring. We can use information technology to link the two as a lunar project, so that students can explore independently. Therefore, to learn this lesson, we should not only understand the knowledge of landing on the moon, but also carefully build a "bridge", transfer this lesson to the comprehensive study of this unit, and seriously carry out scientific and humanistic exploration activities about the moon.
Student analysis
The students in this class are more active in class and have their own personalities, thoughts and unique views. The students in this class have strong information technology ability, good computer skills, knowledge of networks and websites, frequent online information search, collection, processing and processing capabilities, so they study in groups and explore online, and provide technical support for students' online exploration with computers as tools. Most students can independently complete the tasks assigned by teachers and have certain creative ability. Therefore, in teaching, students can study and explore independently, and cultivate various abilities in the process of autonomous learning. For example, before class, students can make some hand-made works related to the moon or draw a map of the moon, and draw a moon landing trajectory map during class, and stick better works on the wall, which not only cultivates students' hands-on ability, but also creates a good learning atmosphere and stimulates students' interest in learning. Let students question the common sense and text of landing on the moon, which can cultivate students' inquiry ability; Let students surf the Internet by themselves and make their own choices in the process of surfing the Internet, which cultivates students' ability to collect and process information and acquire new knowledge. After summing up, we should report to the cooperation group and the whole class, which enhances the students' oral expression ability and communication and cooperation ability.
Preparation before class
Teacher: Understand the knowledge about space flight and the moon, and do well the courseware of this lesson and the website related to the moon.
Student:
1. You can read related books, such as Space Age, Mystery of the Universe, 100,000 Why, and so on. You can also look up information about the moon on the Internet to prepare for a better understanding of the text.
2. Works about the moon.
Teaching design
First, the introduction of new courses.
1, (students' point of view) show students' small productions (handmade works and pictures about the moon, etc. ) and introduce them into the world of the moon.
2. Prepare (from the teacher's point of view) the Goddess Chang'e flying to the moon's stories or ancient poems about the moon (Poems on a Quiet Night, Tune in the Middle Tune, a night-mooring near maple bridge, etc.). ).
Read the poem about the moon written by the students on the slide. The purpose is to create a good atmosphere, arouse students' interest in reading this lesson, and let students feel that the legend and mystery of the moon are human yearning.
(Instructed by the teacher) The moon has had an indissoluble bond with people since ancient times, and is especially loved by poets. The bright and quiet moonlight, full of changing moon shapes when it is round, arouses the poet's nostalgia and emotion. What other poems about the moon do students know? Please use the moon to say a poem ("Yang Liuan, the breeze is fading away", "When will the bright moon shine on me in Jiang Nanan", "Pear Garden melts the moon" and "The thin shadow is shallow, and the faint fragrance floats on the dusk moon." ), the moon is so beautiful under the poet's description, now we will take a walk on the moon with space heroes and feel that thrilling moment.
Second, read the text quickly and feel the main idea of the article.
1, ask students to read the text quickly and grasp the main idea of the article.
(autonomous learning. )
(1) Read the text quickly and silently (don't read, don't move your lips, don't read back), get important information, and answer questions on the moon courseware. (Develop the ability to read quickly)
When did man land on the moon for the first time?
Which country and which astronaut first set foot on the moon?
How far is the moon from the earth?
(4) What is the name of the rocket and the name of the spaceship?
⑤ What order is used to describe what process?
⑵ Use the above information to summarize the contents written in this article. (Time, place, people, events)
⑶ Find out the words that indicate time during the moon landing. The whole process of thinking about landing on the moon can be divided into several stages.
(Summary and Comment) This paper truly records the whole process of American astronauts Armstrong, Collins and Aldrin landing on the moon. The whole process of landing on the moon can be divided into four stages: preparation for landing on the moon-launch of spacecraft-successful landing on the moon-return to the moon.
2. Show students' works and cultivate students' hands-on and speaking ability.
(You say, I say, everyone says)
(1) Try to draw a schematic diagram of the whole process of landing on the moon and briefly explain it.
(2) Compare in groups of four to see who draws best and introduces most accurately. Recommend a classmate to show it, which is introduced above.
(3) Show the best works of each group and ask a classmate to introduce the process of landing on the moon.
⑷ Use the moon landing courseware to show the trajectory map of the moon landing at that time, and understand the process and trajectory of the moon landing.
The moon landing pictures drawn by students can be displayed by physical projectors, so that students can explain themselves and exercise their association and expression skills, which is also the overall perception of the text. Teachers can also make pictures for students to compare and learn.
Third, learn to appreciate, stimulate interest and taste language features.
1, (watch the video in the courseware) to stimulate students' interest in inquiry.
(1) Watch the live video of landing on the moon.
(2) Tell me about the feeling of seeing this scene.
(3) Questioning the moon landing.
Students ask each other questions, or teachers and students ask each other questions, forming a process of discussion and communication, which makes this class reach a climax.
What's on the moon? What kind of world is that?
Why do scientists collect soil and rocks on the moon?
(3) How do astronauts feel when landing on the moon?
The article said, "When returning, the astronauts left the lunar module in space." Is this appropriate?
⑤ How to separate and dock the lunar module with the spacecraft?
Teachers can guide students to speak freely, as long as the imagination is reasonable, allowing students to have different views and fantasies. The teacher can also make an adjustable answer: there are mud, stones and mountains on the moon, no air and water, and it is desolate and lifeless; Scientists collect soil and rocks for scientific research, development and utilization of the moon; Astronauts' feelings at high altitude are weightlessness, dizziness, vomiting, fainting and so on. Space junk is also a big hidden danger to human beings.
2. Teachers guide students to ask each other questions and explore the text together, which will have a profound impact on the human body. (cooperative investigation)
(1) Explore 1: The students' explanation of the process of landing on the moon is accurate, thanks to the author's clear description of the complicated process of landing on the moon. What do you think is the most worth learning in writing?
Let the students talk about their real experiences and speak freely. One thing must be clear: a, the writing method of describing the event process clearly and orderly in chronological order. B, the description is appropriate, and there are comments in the narrative. C. Illustration) These three points can be illustrated by examples, and their functions can be analyzed to teach students to use them in writing.
(2) Question 2: Do you like this text? How did you feel when you were studying (feeling nervous and proud)? What impressed you the most? Please find out the answer, read aloud and comment.
(3) Inquiry 3: Read the last paragraph together and talk about your understanding of the significance of landing on the moon.
(Debate) It is said that 400,000 people and more than 20,000 companies invested in this moon landing, costing 23.9 billion US dollars, consuming a lot of manpower, material resources and financial resources, but only bringing back hundreds of kilograms of moon rocks and moon soil. Is it worth it?
(Summary) On the above issues, the group discussed and reached a consensus under the guidance of the teacher: the first time man set foot on the moon, it took 95 hours to travel back and forth 760,000 kilometers. Astronauts went to the moon to collect samples of lunar soil and moon rocks, erect monuments, install cameras, install solar wind measuring devices, lunar seismographs, insert American flags, and talk to President Nixon. The last paragraph of the text reveals its great significance. Teachers can sum up the transformation: the success of Apollo moon landing program made human dreams come true, and human beings began to go to planets other than the earth. Modern science and technology have reached the level of developing into outer space. This is not only a great leap for mankind, but also the first step for mankind.
What do you know about the moon?
(extended to comprehensive learning-exploring the mysteries of the moon)
1. Students can find information about the moon on the Internet, or they can go to the moon network prepared by the teacher and choose their favorite content to find it.
With regard to the topic of "Moon", students can choose one aspect of this topic that they are interested in to form a collaboration group (taking the topic of "Moon" as an example, those interested in literature can form a moon legend group, a moon poetry group, a moon reputation group, a moon custom group and so on. People who are interested in science can form a moon landing team, a moon overview team, a moon mystery team, etc. ), and each group can make their own choices and activities online. Let each student actively take personal responsibility in this task. Students support and cooperate with each other in the activities. When they encounter problems on the Internet, they can solve them through consultation, solve the contradictions in the group through effective communication, handle the tasks shared by everyone in the group, and jointly evaluate the effect of the activities. In this process, it not only mobilizes each student's participation consciousness and learning enthusiasm, but also improves learning efficiency and cultivates students' various abilities.
2. Each interest group will make the collected courseware.
3. Each group exchanges information from different angles:
(1) Wonders of the Starry Sky
(2) the mystery of the moon
(3) China Aerospace
(4) Moon landing plan
5. A trip to Apollo.
[6] Atlas of Moon Landing
Verb (abbreviation of verb) abstract
The success of landing on the moon is a great feat of mankind and the crystallization of human wisdom. More than 30 years have passed since this moon landing, but China's space technology has still failed to land on the moon. China has already made a space voyage without real people, and the day when the five-star red flag is planted high on the moon is not far away. I hope everyone will study hard when they grow up and make contributions to the development of China's space industry. We also look forward to the early success of China's moon landing program.
Sixth, homework
Required questions:
1. Learn the words in the "Reading and Writing" exercise by yourself and write a paragraph with some of them.
2. Create a situation according to Exercise 3 and write a paragraph of one or two hundred words.
Topic selection: After class, continue to read books related to the moon or check relevant information on the Internet, and take notes.
Teaching reflection
Through the teaching of this class, as well as students' online inquiry activities and feedback, I think this inquiry activity has some gains:
1. The integration of information technology and network technology with Chinese teaching makes information technology, as a tool for students to learn and explore, penetrate into the process of teachers' "teaching" and students' "learning", and has incomparable advantages over traditional teaching methods. Stimulate students' interest in learning and exploration and promote the cultivation of students' abilities in all aspects.
2. Using the richness and interactivity of resources on the Internet, students can retrieve and process information through the Internet, which greatly expands the extension of teaching space, time and information.
3. Make use of the characteristics of hypertext on the network and the natural association of human thinking, let students think independently and explore actively, give students the use and control of information, give full play to their enthusiasm, initiative and creativity, reflect their dominant position in teaching, and realize autonomous learning.
4. Network group cooperation and personalized teaching can realize differentiated education and cultivate the spirit of sharing and cooperation with others.
This lesson also has some shortcomings in the specific teaching:
Students' basic level of information technology is different. In group cooperation, some team members can't finish information processing within the planned time. The initiative of students' network exploration is insufficient; Due to the limitation of class hours, it is difficult to complete the extracurricular inquiry task.
