Epiphyllum original, second grade primary school Chinese
Epiphyllum was originally grown in Mexico, Guatemala and other countries. The climate there is particularly dry and hot, and the sun is like fire during the day. If the epiphyllum blooms in the daytime, its petals and stamens are easily burned to death. As a result, epiphyllum slowly developed the habit of flowering at night. Under normal circumstances, an epiphyllum can bloom more than a dozen flowers at the same time, often in summer or early autumn. When night comes, the buds will quietly open and give off a faint fragrance. The snow-white flower looks very elegant in the moonlight, just like an elegant beauty.
After the epiphyllum blooms, it can only last for four to five hours, and then it fades. Because the flowering period of epiphyllum is very short, people call it "a flash in the pan".
Epiphyllum teaching plan for second and second grade.
Analysis of learning situation: Senior two students have acquired certain reading comprehension ability and cooperation ability, and can preview the text under the guidance of teachers. In the usual training, they have initially learned the problematic learners and cooperated in group research.
Design concept:
Chinese is a practical course, and classroom teaching is the process of Chinese practice. Based on the teaching philosophy of "simply teaching Chinese and seeking development in a down-to-earth manner" and the principle of "independence, cooperation and application", I will issue a preview outline to guide students to preview independently and conduct research on one of the problems in groups. In class, we should combine independent perception with cooperative communication, perceive the characteristics of epiphyllum from words, understand the meaning of "fleeting", and then realize the writing method of grasping the characteristics of plants.
Teaching objectives:
1, read the text correctly, fluently and emotionally, and know the new word 10.
2. Understand the characteristics of epiphyllum and the meaning of "ephemeral", and understand "who or what is ephemeral in ancient and modern Chinese and foreign calendars".
3. Feel the way to describe plants by grasping their characteristics. You can observe a plant and master its characteristics and introduce it to you.
Teaching focus:
Read the text correctly, fluently and emotionally, and know the new words 10.
Teaching difficulties:
Understand the meaning of "a flash in the pan" and combine the pre-class investigation to understand "a flash in the pan in ancient and modern Chinese and foreign calendars".
Teaching process:
(1) Direct introduction:
Students, in this unit, we learned two texts. The plant mother has a way. The bird and Petunia know Bo Gongying, Xanthium sibiricum, peas, impatiens, grass and Petunia, each with its own characteristics. This "happy reading room" introduces us to a strange and precious flower-Epiphyllum teacher's blackboard writing.
What are the characteristics of epiphyllum? Let's go into the text and have a look!
(B) check reading the text, understand the main idea of the article:
1. Use the teacher's demonstration to show difficult sentences and correct pronunciation.
2. Read the text in the natural paragraph by name.
(3) Read the text intensively and experience the characteristics.
1. Read the text quickly with syllables. Thinking: What are the characteristics of epiphyllum mainly introduced in this paper? Draw sentences with lines. [Students can read freely and draw while reading]
2. Communicate with the whole class.
(1) Open at night.
(2) The color is white, the flowers are big and fragrant.
(3) Short flowering period.
Further research on communication;
Teacher: Why does Epiphyllum bloom at night? The students in the first group studied the problem. Please report to the first group. Play the presentation 1
Teacher: We say that the fittest survive, and plants are also adapting to the environment! Epiphyllum blooms at night to adapt to its growing environment, which has long been its growing habit.
② Just now, another feature of Epiphyllum was mentioned in the introduction of the first group of students. In order to survive in a dry and hot environment, Epiphyllum not only chooses to bloom at night, but also what are its characteristics?
Default: Epiphyllum is open for a short time, usually only three or four hours.
Teacher: So people call it a flash in the pan. "A flash in the pan" originally meant a short opening time, and there is another meaning! Draw in the text with horizontal lines!
The whole class exchanged the metaphorical meaning of "a flash in the pan".
Teacher: What are the "short-lived" people and events in ancient and modern Chinese and foreign calendars? Please let the second group introduce you. [Show Student Demo 2]
Teacher: Rare things, prominent figures appear and disappear quickly. We can all describe them as "a flash in the pan", which is its metaphorical meaning.
Teacher: What are the characteristics of Epiphyllum?
Default: white flowers. Write in the text [show the article with the teacher's demonstration]
Teacher: Is there a word to describe the epiphyllum flower?
Default: concise and elegant.
Teacher: Which of these flowers do you think can be said to be simple and elegant? [Show pictures of several flowers]
Default: Lotus, Impatiens and Cherry Blossoms can be said to be simple and elegant, while strings of red and Chinese rose flowers are bright.
Teacher: The author just grasped the characteristics of epiphyllum, which is white, big and fragrant. It opens at night, only for a few hours. Epiphyllum concentrated its excitement in those short hours. Want to see the process of epiphyllum opening? [Play video]
Teacher: How do you feel after watching the clip just now? Let's read the beauty of epiphyllum! [The whole class reads the sentence of epiphyllum opening]
Teacher: Students, the author introduced the growth characteristics and appearance characteristics of epiphyllum to us in very concise language, and also introduced idioms about epiphyllum. In this way, people who have never seen epiphyllum will read the words as if they had seen epiphyllum. It seems that only by grasping the characteristics can we leave a deep impression on readers.
Before class, the teacher asked you to observe a new plant. Now, let's invite the students in the third group to introduce the plants they have observed. Pay attention to the other students and see if you can guess what they said. [Student Presentation 3]

Reflections on the teaching of epiphyllum in the second grade of the third grade primary school
This paper introduces the characteristics of epiphyllum and the meaning of "transience" in concise, vivid and accurate language. Through the study of the text, students can understand the characteristics of epiphyllum, initially understand the meaning of "epiphyllum" and deeply understand the metaphorical meaning of "epiphyllum". At the same time, by reading the text, let students feel the writing method of grasping the characteristics of plants, and observe their favorite plants after class, grasp their characteristics and introduce them to everyone, so as to know more about the characteristics of plants and feel the beauty of nature, and then love nature and life more. First, the teaching effect: read the text repeatedly to achieve proficiency. Draw words describing the characteristics of epiphyllum, communicate with students in the group and accumulate them, and then report by name. In the report, the teacher should guide the students to read the metaphor sentence "The weather there is particularly dry and hot, and the sun is like fire during the day." Anthropomorphic sentence "When the night comes, the bud will quietly open and give off a faint fragrance. Snow-white flowers look very elegant in the moonlight, just like slim beauty. " Based on reading, let students know epiphyllum in reading, understand the meaning of the idiom "fleeting", satisfy students' curiosity and thirst for knowledge, and gain something from reading. Through many articles, expand reading and stimulate students' interest in exploring nature. Let students ask questions independently, explain and train in cooperation.
Cultivate students' initial problem consciousness and inquiry spirit, so that students can build their self-confidence in the process of asking and solving problems, and further feel the joy of reading. Students who can ask questions already know the answer to the question. After discussion, other students who didn't expect these questions can have a deeper understanding of the content of the article. The questions that students didn't ask in the above questions were all put forward by teachers in the form of questions, which were collective thinking and answers.
2. Success: This paper introduces the characteristics of epiphyllum and the meaning of "transience" in concise, vivid and accurate language. Through the study of the text, students can understand the characteristics of epiphyllum, initially understand the meaning of "epiphyllum" and deeply understand the metaphorical meaning of "epiphyllum". At the same time, through reading the text, let students feel the writing method of grasping the characteristics of plants, and observe their favorite plants after class, grasp their characteristics and introduce them to everyone, so as to learn more about the characteristics of plants and feel the beauty of nature, and then love nature and life more. Chinese is a practical course, and classroom teaching is the process of Chinese practice. Based on the teaching philosophy of "simply teaching Chinese, seeking development in a down-to-earth manner" and the principle of "independence, cooperation and application", in class, we should combine independent perception with cooperative communication, start with words to perceive the characteristics of epiphyllum, understand the meaning of "fleeting", and then realize the writing method of grasping the characteristics of plants.
3. Disadvantages: Junior three students have a certain reading ability, but their understanding ability is still a little poor, and it is difficult to understand the words with strong knowledge in the text, such as germination, elegance, prominence and disappearance, which are all unfavorable factors in teaching.
Fourth, improvement measures: children in this period have the psychological characteristics of curiosity, love to explore and easy to be infected, and are easily attracted by new things. They will have a strong thirst for knowledge about the text, introduce extracurricular reading into the classroom, and then introduce it between classes, so as to expand the reading surface, increase the reading volume and broaden students' horizons. This is a favorable factor in teaching.
