The teaching content, teaching steps, teaching methods, blackboard design, teaching methods, teaching time, etc. in the lesson plan must be carefully considered and carefully designed, reflecting a strong sense of planning. Below I have compiled the lesson plan for you in the fourth grade Chinese language volume "Dinosaurs Flying to the Blue Sky" for your reference. I hope it will be helpful to you!

2. Understand the evolution process of dinosaurs flying into the blue sky, and stimulate students' interest in dinosaur research and exploration.
Understand the writing of accurate words and sentences in the text, and learn to describe the development process of things in order.
3. Teaching Strategies
"Dinosaurs Flying to the Blue Sky" is a popular science article that mainly introduces people to a hypothesis put forward by scientists based on research: Birds are probably A descendant of a small dinosaur. At the end of the 20th century, Chinese scientists discovered for the first time dinosaur fossils with feather impressions in western Liaoning, providing evidence for people to imagine the evolutionary process of dinosaurs flying into the blue sky and transforming into birds. The article not only reveals the major discoveries made by scientists in paleontology research, but also opens a scientific door to students to explore paleontology, arousing their strong interest in science. The following strategies can be adopted when teaching:
1. Highlight the essential characteristics of the Chinese subject. Chinese is composed of language and characters. Learning Chinese and writing should be the ultimate goal. Only based on the acquisition and expression of language In order to reflect the standard of the discipline. During the entire teaching design process, students are guided to carefully understand the characteristics of text expression and understand the accuracy of the language.
2. Reflect the subjective role of students, that is, students are the masters of learning. The process of language practice, including perception, understanding, accumulation, and application, should be conducted in an orderly manner with students as the main body and based on self-reading and insights.
IV. Teaching Process
(1) The conversation is exciting and introduces new lessons
1. Talk about your knowledge and understanding of dinosaurs and birds: According to Student responses produce and understand the words.
Present courseware:
Bulky; slow; light; agile; soaring in the air.
2. Dinosaurs and birds seem to have nothing to do with each other in terms of appearance or living habits. They are extremely different animals. I never expected that birds evolved from dinosaurs. Want to know how scientists discovered it? Let us find the answer in the text "Dinosaurs Flying into the Blue Sky".
3. Read the topic together.
(2) First reading of the text, overall perception
1. Read aloud freely and see who can read it accurately.
2. Read the text by name and grasp the main idea of ??the article as a whole. Communicate after reading to understand the main content of the text.
(1) How did scientists discover that dinosaurs finally turned into soaring birds after a long evolution?
Show courseware:
In the Mesozoic Era During this period, a branch of dinosaurs went through a long evolution and finally turned into a soaring bird.
(2) How did dinosaurs fly to the blue sky? That is, what was the evolutionary process of dinosaurs flying to the blue sky?
(3) Go deep into the local area and read and comprehend
1. Feeling "ecstatic".
(1) Students read the text silently, looking for and describing the discoveries that researchers were ecstatic about.
Students read the second natural paragraph of the text silently, and then try to describe the researchers’ findings in their own words. Based on the students' answers, the teacher uses multimedia courseware to describe the similarities in bone structure between dinosaurs and birds, the evidence that dinosaurs and birds are related, and that dinosaurs should have feathers.
Show courseware: information bag.
In 1966, a small carnivorous dinosaur fossil specimen called "Sinosauropteryx" was discovered in rocks deposited about 125 million years ago in the western Liaoning region of my country. Chinese scientists discovered that this dinosaur's body was covered with a layer of "hair"-like skin derivatives. This is the first time in history that feathers have been found on the body of a non-bird animal, and this discovery provides strong evidence for the hypothesis that birds originated from dinosaurs.
(2) Read the sentences and experience the joy of the researchers.
Read the sentences aloud to yourself and think about it in conjunction with the text. What do you think the role of these discoveries is?
Show the courseware:
The discoveries in western Liaoning showed the world the dinosaurs The evidence of feathers adds the finishing touch to the picture painted by paleontologists.
2. Read and understand the evolution process of dinosaurs flying into the blue sky.
(1) The deskmate reads the fourth natural paragraph using the contrastive reading method.
(2) Fill in the form. What did you understand in this paragraph?
Summary: The evolution process of dinosaurs flying into the blue sky and the time for dinosaurs to change are long; the characteristics of dinosaurs are diverse; the reproduction situation depends on the dinosaur family is huge.
Provide courseware:
An explanation of the characteristics of a large family with different shapes
Some run on two legs? In terms of living habits
Some Walking on four legs
Some are tens of meters long and weigh dozens of tons. Physically
They are small in stature and weigh less than a few kilograms
Some are ferocious and abnormal. Ruining hair and drinking blood? In terms of temperament
Some are docile and cute, and feed on plants
(3) What is the evolutionary process of dinosaurs flying into the blue sky? Let us develop a rich and reasonable explanation based on the text phenomenon, integrate what you know about dinosaur evolution, and then explain it in your own words in an organized manner.
① First speak in an organized manner in your own words, and the teacher will patrol and guide.
Show the courseware:
Read the text and fill in the blanks below.
The body (gradually becomes smaller─body surface (feathers grow)─transfers to (survives in trees)─jumps among trees (jumps, lands)─has (gliding ability)─finally (Able to fly actively)
② Ask the students if they have different opinions.
③ Read the text again to deepen understanding.
(4) Students, have all dinosaurs evolved into birds? Which type of dinosaurs evolved into birds? Did this evolutionary process happen overnight?
From this sentence What characteristics can middle school students realize in the author's language expression? What other words and sentences in the text make you realize this characteristic?
Show the courseware:
Among them, some hunting The bodies of food-eating dinosaurs gradually became smaller, and they looked more and more like birds...
Present the courseware:
Some of them may have evolved to avoid predators or find food. Move to trees to survive.
Present courseware:
These arboreal dinosaurs jumped and landed between trees, gradually acquired the ability to glide, and eventually were able to fly actively. < /p>
Present courseware:
According to this hypothesis, some dinosaurs that are closely related to birds should have feathers, but the relevant fossils have not been found.
(4) Summarize the full text and stimulate the desire to explore
Transition: After a hundred years of hard research, scientists have helped us understand the evolution process from bulky dinosaurs to light and flexible birds. All this condenses How much precious efforts they put in! But they did not stop there, they had a better wish in their hearts!
1. Read the last paragraph together
Billions of years. In the past, a kind of feathered dinosaur broke away from its kind and flew into the sky, evolving into today's bird family.
2. Do you think this is possible? ? Tell us what you think.
Discussion:
Through dinosaur fossils, scientists can deduce the evolution process of dinosaurs into birds.
What do you think about this?
