Teaching time

teaching process

First, the examination questions and doubts

Write on the blackboard and read the questions.

What will an ordinary map of the world lead to? Read the text with this question.

Second, read the text by yourself

1, read the text by yourself. Read correctly and read fluently. Understand words in context.

2. Self-study feedback. Put forward words that you don't understand, and teachers and classmates will help solve them.

3. Read aloud by name.

4. Explain the question raised by the topic: Who discovered what under what circumstances?

5. Find out the relevant paragraphs of the text and read it again.

Third, observe and read the text and confirm each other.

1. Observe the world map or globe in groups, find the Brazilian land in South America and the Gulf of Guinea on the west coast of Africa, and see if it is as Wei Gena said. Let's see if other land is similar to the coastline.

2, familiar with the fifth paragraph "brand-new whimsy". Tell me if this fantasy is the same as what we just observed.

Study the evidence, explore the process

Transition: In order to prove whether his findings are correct, Wei Gena has done a lot of painstaking textual research, looking for evidence from a huge amount of information. It turned out to be a very convincing message.

Study the seventh paragraph to sort out Wei Gena's reasoning process.

Student discussion and teacher guidance:

Zhonglong is a reptile, which is found in Brazil and Africa. It is impossible for reptiles to fly across the ocean, which proves that Zhonglong lived on the same continent at that time.

Four, familiar with the text, exchange feelings

1. Students read the full text silently.

2. What did Wei Gena's great discovery depend on? How do you feel from this matter?

Let the students talk about this problem.

Looking for evidence of vibration.

Reflection after teaching

When students exchange their reading feelings, I participate. As a reader, I revolve around "What is the great discovery of Wei Gena?" The equal communication with students on this issue makes students realize that careful observation, careful thinking and repeated argumentation are indispensable factors for Wei Gena's success. When students' feelings are sublimated and their thoughts are not finished, they can be encouraged to continue to consult other materials about the theory of continental drift and stimulate their interest and desire to continue exploring science.
