Teaching process and methods
First, the introduction of new courses.
Play the animal world without explanation before class, and add explanations to make students understand the importance of explanations.
Second, the new lesson learning
Step 1: Through the study of the text, I hope students can understand the characteristics of comments and clearly write the main points of comments.
1. Set the situation-if you want to provide commentary for promoting our school's documentary, guide students to think about the characteristics of commentary in combination with reality.
Q: What do you think is the key to writing a good review?
After the students answered, the teacher and students * * * made it clear that:
The characteristics of the commentary mainly include the following points:
(1) the commentary should have a clear and reasonable explanation order.
Commentary should have a clear theme and focus according to the characteristics of the narrator.
(3) The commentary should appropriately supplement and expand the object of interpretation.
2. The order of explanation is the key factor of explanation effect. Please scan the text quickly and find out the explanation order of this article on the basis of preview. (The teacher gives method guidance)
After the students answered, the teacher and students * * * made it clear that:
Explain the order-spatial order, from far to near.
Cosmic galaxy-star-solar system-planet.
Step 2: Through careful reading of the text, I hope students can understand the ideas passed on to us by the author.
1. A good commentary, in addition to the above characteristics, is also a spiritual dialogue and spiritual exchange between the author and the audience from a literary or humanistic point of view. So, which sentences are the carriers of this kind of dialogue and communication? -Arguments and lyrical statements. (Explain the different functions of expressions)
Ask the students to quickly mark the sentences used by the author in the article. Read these sentences carefully in the context and taste what the author wants to convey. (Explain the meaning of important sentences in the text)
Teachers and students communicate with each other.
Example:
The object I respect should not be space, but my soul. If I have everything, I have no intention. Ambition is swallowed up by the cosmic Wang Yang, and you can understand the world by using your brain. -blaise pascal "Impression"
Reading: facing the boundless space, human beings should not be arrogant and utilitarian; Pascal said that man is a thinking reed. People are actually extremely weak, but weak people gain great ideological strength by examining and thinking about their own souls. We use this power to respond to the call of the unknown world, so as to further understand the world and stimulate the vitality of life and thought. At the same time, the vast universe laughs at the so-called arrogant conquest. Through understanding and thinking, we deeply realize the subtle connection between the universe and us.
Another example is:
As long as we think about the universe, it is difficult for us to be calm-our mood is excited and sighing, just like remembering a cliff slide a long time ago. (first paragraph)
From a macro point of view, most of the problems that human beings care about can be said to be irrelevant or even insignificant. However, we human beings are full of vigor and vitality, brave and eager to learn, and have a bright future. (second paragraph)
These exploration activities remind us that curiosity is human nature, understanding is a pleasure, and knowledge is the premise of survival. (second paragraph)
When we explore the universe, we should be both skeptical and imaginative. (third paragraph)
Supplement: Famous sayings about curiosity, imagination and questioning spirit guide and encourage students.
