About lectures

I. teaching material analysis

Study hard and learn by yourself is a text in the tenth volume of the new textbook. This text tells the story that Hua did not fear difficulties, studied hard, and finally became a master of mathematics in China, praising his spirit of self-study through hard work, and telling us that self-study can also achieve great things as long as you are diligent. The text tells the story of Hua's self-taught success in three stages: Hua loved to bury himself in math problems when he was young. After dropping out of school, Hua mastered all the math courses in high schools and universities through self-study. Hua published a paper at the age of 65,438+09, which shocked the domestic math community.

Second, the analysis of learning situation

In the next semester of the fifth grade, under normal circumstances, students can read a text by themselves, with the help of reference books or through group cooperation, and students can inspire and understand each other. On this basis, teachers should try their best to implement "autonomous reading" and truly "leave reading time to students". Therefore, it is very important to further improve students' ability to read texts silently. This semester, through the study of texts, the aim is to continuously improve students' ability to read texts silently, gradually improve their reading speed, form a good habit of combining reading with thinking, and strive to "think while reading". Through reading and thinking, students can deepen their understanding of the content of the text and appreciate the infinite charm contained in the article.

Teachers should also fully tap the writing resources of texts, design language training, reading and writing combination and various language practice activities, and comprehensively improve students' ability to use languages.

In addition, through the study of the text, students should be educated to be "diligent", so that students can truly understand the importance of diligent study in the final stage of primary school study, and can really put their consciousness into action.

Third, the teaching objectives

According to the curriculum standards, the teaching objectives at this stage and the actual situation of this class, the teaching objectives of this course are formulated:

Objective 1: In the language environment of the text, understand the meaning of words such as "completely ignoring, sweating like rain" through the context. By grasping the key words, we can understand how Hua taught himself diligently, and then understand the text, and know that his great achievements in mathematics are the result of diligent self-study.

The focus of this lesson is the part of self-study in China. In teaching, let students understand the meaning of "completely ignoring, sweating like rain" in connection with the context, and let students talk about how China is diligent in self-study on the basis of understanding the meaning. By letting students understand the meaning of words according to the language environment, they can deepen their understanding of the words being used and help to understand the main idea of the article.

Goal 2: Read the text 1-8 with emotion, and understand the relationship between this part of the content and the center of the article.

The center of the whole paper is to express Hua's spirit of "diligent self-study", and the part of 1-8 is exactly what happened when he taught himself mathematics at the age of 10. The author leads the full text with such a story. Helping students to sort out the context of the article aims at cultivating students' writing consciousness and infiltrating this unique writing method.

Goal 3: Write the sentence "Hua can't help being dull when thinking about math problems" in connection with the content of the text and related extracurricular materials.

Many great men are often different in the eyes of ordinary people, and so is Hua. In teaching, let students contact the content of the text and relevant materials after class, so as to realize Hua's selfless spirit of thinking about mathematical problems.

By tapping this writing resource of the text, we design to write paragraphs in the form of total score structure to improve students' ability to use language in an all-round way.

Fourthly, teaching design.

After studying the teaching materials and setting the teaching objectives, I designed the teaching according to the above ideas (see the lesson plan design section for details), focusing on the following points:

(A) from the "topic" to find learning clues.

At the beginning of the semester, the teacher can help students understand the meaning of the topic. "Great ability" means "a person who can undertake great undertakings", and then judge the key word of the topic "study hard and practice hard" to see the topic: Who is "study hard and practice hard"? Why should he study hard by himself? How to study hard by yourself? After reviewing the questions, help the students understand the text as a whole. On this basis, we further study how Hua is diligent in self-study, and finally go back to the whole, and make it clear that Hua's great achievements in mathematics are inseparable from his long-term diligence in self-study. When teaching, the teacher starts with the title of this text to help students find good clues to learn the text.

(B) from the study of "life profile", approached the characters.

In order to further help students approach China, teachers can also let students silently read and think about this profile and talk about their own understanding of China when introducing biographies. Through this language training, students can get an overview of the characters from their identities, life backgrounds, achievements and contributions. This kind of language training cultivates students' ability to extract information from the profile of characters and grasp the most prominent aspects of their coherent expression, so as to establish a preliminary understanding of characters, which is very important for learning texts and understanding the spiritual quality of characters.

(B) from reading to writing, the establishment of text awareness

After the students have learned the content of "How does Hua study hard by himself", let the students look back and see what is the relationship between the scene description of Hua 10-0-year-old self-taught mathematics written in the article (section 1-8) and the statement in the center of the article? It is not difficult for students to find out from the context that the center of the full text is to express Hua's spirit of "diligent self-study", and this part of 1-8 is the scene when he 10 taught himself mathematics. The author leads the full text with such a story, which arouses readers' interest in reading. Helping students to sort out the context of the article aims at cultivating students' writing consciousness and infiltrating this unique writing method.

Reading is the basis of writing. Writing requires not only language accumulation, but also some basic knowledge of writing. Therefore, reading teaching should also teach students some language knowledge, as well as the narrative rules and methods of writing. Taking the text as an example, let students understand how and why the author wrote it, and understand how the author accurately, vividly and vividly narrated it to express the center. This combination of reading and writing enables students to learn writing from reading.

(D) the combination of reading and writing, sublimation theme

At the end of the study, the teacher can ask the students to contact the content of the text and related materials after class and write the sentence "Hua can't help but look dull when thinking about math problems". At the beginning of writing, students can grasp the word "stupid" to understand. The understanding here does not mean that Hua is not quick-witted and slow-witted. It means that he is too absorbed in thinking and looks slow. Then let the students choose relevant materials to write. This writing training aims at guiding students to grasp the image of the protagonist in the process of language understanding and application, enlightening people with literature and promoting extracurricular reading.
