2. Can use "if...then..." and "sure enough" to make sentences.

3. Teaching preparation

Physical projector; students prepare brushes and white paper.

Teaching strategies

1. Stimulate learning through questioning.

“Learning starts from thinking, and thinking starts from doubting.” Piaget said: Children are proactive people, and what is taught must arouse children’s interest and meet their needs. effectively promote their development. Indeed, our teaching should be in line with children's needs and development patterns. At the beginning of teaching, the topic is introduced by showing the "stethoscope" object. Students will naturally want to know about "the world's first stethoscope" and will become interested in the text they have learned. Reading with the desire to solve doubts will improve their knowledge. Improve the pertinence of reading and learning.

2. In-depth dialogue in hierarchical reading.

Reading teaching should go back and forth several times in language and text, and should focus on the guidance of "emotions, attitudes, and values". After reading and solving doubts, arrange to read the text again and talk about their feelings and thoughts based on the text. This can enable students to enter the text and the protagonist again. At the same time, they can gain emotional release through communication.

3. Effective training in reading dialogue.

While comprehending the text, Chinese language teaching must not ignore the training of Chinese language ability and thinking ability. The cultivation of ability cannot be done in vain. If you find the germination point and train it, you can get a variety of effects. When guiding the sentence making of "if... then...", grasp the sentence in the text - if a person has a disease, his internal organs will move abnormally. Show four sentences with the words "if... then..." and fill in the blanks around the text content, and make sentences through interlocking reasoning, which not only cultivates thinking ability, but also provides speaking training.

The process of inventing the stethoscope is also divided into two levels. First, the report after the first reading, and then the creative description after the game experience and the addition of imagination, which can make the understanding more profound.

Teaching process design

1. Reveal the problem with physical objects and introduce new lessons.

1． Show the object and ask: What is this?

While writing on the blackboard: Stethoscope, I asked: Who can briefly introduce your understanding of it?

2. Guide questions: What do you want to know when you see this stethoscope?

(Students may ask: Who invented the world's first stethoscope? How was it? Why was it invented? How was it invented?... According to the students' questions, write on the blackboard: The world's first, and Question)

3. Uncover the question, read the question. Teacher transition: This text tells the story of the invention of the world's first stethoscope. If you read this lesson carefully, these problems will be easily solved.

●Use real objects to solve the problem, let students talk about their understanding of stethoscopes, arouse students' perceptual understanding of stethoscopes, and understand its important role in their lives, which can pave the way for subsequent studies. Then, if they question it with real objects, students will naturally become curious about "who invented the stethoscope", "the invention process of the stethoscope", etc., thus stimulating students' interest in studying the text in depth.

2. Read the text for the first time, gain overall perception, and figure out the shape of the world’s first stethoscope.

1． Self-reading, requirements: read the pronunciation of the characters accurately, read the text thoroughly, and think about the questions raised above while reading.

2. Check the reading aloud (using the method of reading in turns), correct the pronunciation and sentences according to the reading situation, and think: Who invented it? What was the world's first stethoscope?

3． Communication:

⑴Who invented it? (Written on the blackboard: Lenek, read with fingertips and read with correct pronunciation)

⑵ What was the world’s first stethoscope like? Can you draw a simple diagram to introduce it?

① Name the board to draw, and the other students will draw by themselves.

②Based on the content of the book, discuss whether it is correct and introduce the shape of the stethoscope by name. (Formal shape: trumpet shape)

4. Summary: Being able to solve these problems is the result of our careful reading.

●Start from the overall perspective and allow students to read the text with questions. The purpose is relatively clear and can improve the efficiency of reading. At the same time, taking the solution of a problem as an example allows students to understand that as long as they study hard, they will be able to solve the problem and enhance their confidence in learning. The third-grade students still have the upper hand in perceptual knowledge. Through reading, drawing, and introducing it, they have an understanding of the appearance of the first stethoscope. At the same time, they also further understand the importance of reading.

3. Read the text again and clarify the paragraphs.

1． Read silently and think: Why invent? How was it invented? Which paragraphs of the text are they?

2. Communicate and clarify the corresponding paragraphs of these contents.

3． Summarize the content of the text.

●The "Course Standards" point out that middle-grade students must be able to initially grasp the main content of the article. Asking students to find passages with corresponding content can enhance the pertinence of reading, and the teacher's timely summary also implies that the text is clearly organized and narrated. Over time, it has a subtle influence on students' homework.

4. Read the first part and find out the reason.

1． Read and think about the reasons.

2. Discussion:

Presentation: If a person has a disease, the movement of his internal organs will be abnormal.

⑴Understanding: Abnormal.

⑵Practice speaking using "if... then...".

①If there is an abnormality in the movement of internal organs,——————————————————————.

②If these changes in the human body can be detected early, then——————————————————.

③If it can be diagnosed in time, then——————————————————————————.

④If tuberculosis can be treated,————————————————————————.

3． Read the first natural paragraph together.

●In Chinese teaching, we should also strengthen the cultivation of critical thinking ability. In this link, we should grasp a key sentence as the starting point, let students reason in succession, and understand the connection between contexts. Developed thinking ability and conducted speaking training, achieving the effect of "killing two birds with one stone".

5. Read the second part to understand the process of invention.

1． Read to yourself and think about the process of invention.

2. Communicate and speak in your own words. (Group discussion, lobby communication and review.)

3. Play games together at the same table: lightly trace the table with your fingers, listen with your ears close to the desk, and experience it personally.

4． Use "sure enough" to talk about the game just now.

5． Quote verses 2-4, and stimulate your imagination at the right time: [Laneke tried it, and the sound really came along the board. (Imagine: At this time, he will think:——————) He is very happy,————-. He put one end of the stick———— and the other end————. ah! ——————(Guide to read out the surprise.) (Imagine: At this time, Reneck————————) Just like that, ————, and then————. Later, Reneke discovered again——————. So, he————————, and this became the world’s first stethoscope. ]

6. Retell the story of the invention.

●Experience is the process in which children gain real feelings through personal experience and practical activities. This inner experience accompanied by rich emotional activities is the basis for forming understanding and transforming it into behavior. Moreover, after experiencing it, one’s understanding will be deeper. During the teaching, by letting students play games, they gained experience, gained a feel for the feasibility of the stethoscope, and gained an appreciation for Lenek's joy. At this time, using "Guo Ran" to make a sentence will come naturally. The introduction of imagination deepens the understanding of Lenek's spirit of observation, thinking, diligence, and dedication to medical research. The process of invention was told twice. The first time focused on explaining the outline of the process, and the second time focused on creative retelling, which made a qualitative leap.

6. Read again, comprehend Reinek’s spirit, summarize the full text, and sublimate emotions.

1． Read the text again in the way you like, and talk about what you want to say after reading the text?

2. Communicate, experience and learn from Lenaike’s spirit of loving observation, being willing to use his brain, loving the people, and loving his career.

3． Summary: Any invention or creation is not accidental and requires unremitting observation and research. As long as children are diligent in observation and research, they will gain something.

●Return from the part to the whole, allowing students to enter the text again. Through communication with the open-ended question "What do you want to say?", students can be good at observing and thinking about Reneck. He has a clearer and deeper understanding of the spirit of being diligent in practice and devoted to medical research, which inspired his desire to learn from Lenek, and his emotions were sublimated.

7. Teach students vocabulary.

1． Refer to reading.

2. Remember silently.

3． Communicate the methods of notating words, individual correct shapes: shape, diagnosis, lung

4. Observe the glyphs in the field grid and pay attention to the space-occupying characteristics.

●Learning and memory can improve the efficiency of learning. Arranging students to memorize words during teaching improves students' attention and also exerts their learning autonomy.

8. Homework:

1. Copy the words.

2. Use "if...then..." and "sure enough" to make sentences.

3． Tell your parents how Lenek invented the stethoscope and ask them to rate it.

4． Collect and read stories about scientists’ inventions and creations.

●The design of these four assignments is basic, in-depth, written, oral, and diverse in form. It can be considered from the aspects of listening, speaking, reading, and writing to achieve the purpose of consolidation and expansion.
