Unit 4 Waves of Technology Section 2 Learning Through Practice 教案-2025-2026学年高中英语冀教版必修第二册

Unit 4 Waves of Technology Section 2 Learning Through Practice 教学目标和重难点 教学目标 It focuses on developing students’ language ability to use tech-related words and sentences, cultural awareness of global tech development, thinking quality through logical analysis of tech impacts, and learning ability to practice and summarize independently. 教学重难点 Key points: Master core words (e.g., adapt, breakthrough) and sentence patterns about tech application; finish practical tasks. Difficult points: Use language flexibly in real scenarios and analyze tech’s pros and cons logically. 教学过程 Step 1: Lead-in (Lead-in and Activation) The teacher starts the class by showing a short video clip that includes common technological products in daily life, such as smartphones, cloud computing devices, drones, and smart home appliances. After playing the video, the teacher asks students two questions in English: “What technological products do you see in the video?” and “How do these technologies change your daily life?” Then, invite 3-5 students to share their answers freely. During the sharing process, the teacher guides students to use simple English expressions and properly prompts them with words related to technology, such as “convenient”, “efficient”, and “improve”. After the sharing, the teacher briefly summarizes, pointing out that technology is like waves, constantly advancing and affecting every aspect of our lives, and naturally leads to the theme of this lesson—Learning Through Practice, which focuses on applying the knowledge learned in Section 1 to practical scenarios. Design Intention: The video clip is intuitive and vivid, which can quickly attract students’ attention and arouse their interest in learning. By asking questions and encouraging students to share, it can activate students’ existing knowledge reserve of technological vocabulary and daily experience of technology, lay a foundation for the subsequent practical tasks, and also help students quickly enter the English learning context, reducing their psychological pressure in English expression. Step 2: Review and Consolidation (Review of Key Knowledge) First, the teacher reviews the core vocabulary and sentence patterns learned in Section 1. The teacher presents the words on the blackboard or multimedia courseware, including adapt, breakthrough, expand, recommend, relieve, efficiency, privacy, etc. For each word, the teacher invites students to read it aloud first, then explain its meaning and collocation, and give a simple example sentence. For example, for “adapt”, the teacher guides students to recall the collocation “adapt to” and make a sentence like “We need to adapt to the rapid development of technology”. For key sentence patterns, such as “Technology has made it possible for us to...”, “With the development of..., people’s lives have been greatly improved”, the teacher leads students to read them together and asks students to replace the blanks with different technological contents to practice. Then, the teacher designs a quick matching game. The teacher prepares two groups of cards: one group is core words, and the other group is their corresponding Chinese meanings and collocations. Ask students to come to the front of the classroom in pairs to complete the matching task, and other students judge whether it is correct. For the wrong matching, the teacher corrects it in time and explains again to strengthen students’ memory. After the game, the teacher arranges a short oral practice: students work in pairs to talk about a technological breakthrough they know, using the words and sentence patterns reviewed. Each pair has a short communication, and then the teacher selects 2-3 pairs to present their dialogue in front of the class, and gives appropriate comments and guidance. Design Intention: Reviewing the key knowledge of the previous section can help students consolidate what they have learned, avoid forgetting, and lay a solid language foundation for the practical tasks in this lesson. The form of games and pair practice is more flexible and interesting than simple rote memorization, which can mobilize students’ enthusiasm for participation, improve their oral expression ability, and let students feel the practical value of language knowledge in communication. Step 3: Task-based Practice (Practice and Application) This link is the core part of the lesson, which is divided into three practical tasks. The teacher guides students to complete each task step by step, focusing on cultivating students’ ability to apply language in real scenarios and their logical thinking ability. Task 1: Describe a Technological Product (Individual Practice) The teacher asks students to choose a technological product they are familiar with (such as a smartphone, laptop, smart watch, or photocopier), and describe it in English according to the following requirements: 1. Introduce the name and basic functions of the product; 2. Explain how it helps people in daily life or study; 3. Put forward one suggestion for improving the product. The teacher gives a sample description first: “My favorite technological product is the smartphone. It can be used to make calls, send messages, surf the Internet, and take photos. It makes it convenient for me to keep in touch with my friends and search for learning materials. I suggest that the battery life of smartphones can be improved to meet people’s long-term use needs.” After the sample is given, students are asked to think independently for a few minutes and write down key words and sentences. Then, each student takes turns to describe their chosen product in front of the group. Other students in the group can ask simple questions, such as “What other functions does it have?” or “Why do you want to improve its battery life?”, and the describer answers them in English. During the process, the teacher walks around each group, observes students’ performance, and provides timely help for students who have difficulties in expression—such as prompting words, correcting grammatical mistakes, and guiding students to organize language more logically. After the group presentation, the teacher selects 3-4 students with different performances to present in front of the whole class. For students who perform well, the teacher affirms and praises them, emphasizing their accurate use of vocabulary and fluent expression; for students who have deficiencies, the teacher gives patient guidance and encouragement, pointing out the areas that need improvement and helping them correct them. Design Intention: This task is an individual practice, which can help each student participate in the learning process and exercise their independent thinking and language expression ability. Choosing familiar technological products can reduce students’ difficulty in expression and enhance their confidence in speaking English. The interaction of asking and answering in the group can further deepen students’ understanding and application of language, and the teacher’s on-site guidance can timely solve students’ problems in learning and ensure the effect of practice. Task 2: Discuss the Impacts of Technology (Group Cooperation Practice) The teacher divides students into groups of 4-5, and assigns the discussion topic: “What are the positive and negative impacts of technological development on people’s lives?” The teacher first lists some guiding questions to help students think: 1. How does technology improve people’s work efficiency and quality of life? 2. What problems may technology bring, such as privacy leakage, addiction to electronic products, etc.? 3. How can we make rational use of technology to avoid its negative impacts? Before the discussion, the teacher reminds students to use the core words and sentence patterns learned in this unit, such as “benefit from”, “lead to”, “solve the problem of”, “in my opinion”, etc. During the discussion, each group elects a recorder to record the key points of the discussion, and a speaker to summarize the group’s views. The teacher walks around each group, guides students to carry out in-depth discussions, reminds students to speak in English as much as possible, and corrects inappropriate expressions in time. For groups that have difficulty in starting the discussion, the teacher gives appropriate prompts, such as “You can talk about the impact of smartphones on students’ study” or “How does cloud computing help companies improve work efficiency?”. After the discussion, each group’s speaker presents the group’s views in front of the whole class. The presentation time of each group is controlled appropriately, and other groups can put forward different opinions or questions after the presentation. The teacher summarizes the discussions of each group, affirms the positive views put forward by students, guides students to have a comprehensive and objective understanding of the impact of technology, and emphasizes that technology is a double-edged sword, and we should make rational use of it to let it serve human beings better. Design Intention: Group cooperation practice can cultivate students’ cooperative learning ability and communication ability, and let students learn from each other in the process of discussion. The topic of technological impact is closely related to students’ daily life, which can stimulate students’ thinking and help them form a dialectical thinking mode. Through discussion and presentation, students can further improve their oral expression ability and logical thinking ability, and at the same time, enhance their cultural awareness and sense of social responsibility. Task 3: Write a Short Passage (Comprehensive Practice) On the basis of the previous two tasks, the teacher arranges a writing task: Ask students to write a short passage with the title “My View on Technological Development”, with a focus on the following points: 1. The role of technology in daily life; 2. The advantages and disadvantages of technology; 3. My suggestions on rational use of technology. The teacher gives writing tips: 1. Use the core words and sentence patterns learned in this unit; 2. Pay attention to the logical connection of the passage, and use transition words such as “firstly”, “secondly”, “however”, “therefore”; 3. Ensure the correctness of grammar and spelling, and the fluency of expression. Before writing, the teacher shows a sample passage to help students understand the writing requirements and ideas. The sample passage is as follows: “With the rapid development of technology, our lives have been greatly changed. Technology brings us a lot of convenience: it makes communication easier, improves work and study efficiency, and enriches our spare time. However, technology also has some negative impacts, such as privacy leakage and addiction to electronic products. In my opinion, we should make rational use of technology, use it to help us study and work, and avoid being controlled by it. At the same time, we should also pay attention to protecting our personal privacy and use technology in a healthy and positive way.” After the sample is shown, students start writing independently. The teacher walks around the classroom, provides timely help for students who have difficulties in writing—such as guiding students to organize their ideas, prompting appropriate words and sentences, and correcting grammatical and spelling mistakes. After students finish writing, they exchange their passages with their deskmates, read and revise each other’s works, and put forward revision suggestions according to the writing requirements. Then, the teacher collects some representative passages (including excellent passages and passages with common problems), comments on them in front of the whole class, affirms the advantages of excellent passages, and points out the common problems in the passages that need improvement, such as unclear logic, incorrect use of words, and grammatical mistakes, and guides students to correct them. Design Intention: Writing practice is a comprehensive test of students’ language ability, which can help students consolidate the vocabulary and sentence patterns learned, and improve their ability to organize language and express ideas in written form. The form of mutual revision between deskmates can let students learn from each other’s strengths and make up for their own weaknesses, and enhance their ability to evaluate and revise. The teacher’s comment and guidance can help students find their own problems in writing, clarify the direction of improvement, and further improve their writing level. Step 4: Summary and Reflection (Summary and Deepening) First, the teacher invites students to summarize the content of this lesson independently. Ask students to think about: “What did we learn in this lesson? What practical tasks did we complete? What new knowledge and skills did we master?” Then, invite 2-3 students to share their summaries, and the teacher supplements and improves them, emphasizing the key points of this lesson: the application of core vocabulary and sentence patterns, the completion of practical tasks, and the comprehensive understanding of the impact of technology. The teacher also reminds students that the focus of this lesson is “learning through practice”, and that only by applying the learned knowledge to practical scenarios can we truly master English and improve our language ability. Then, the teacher guides students to reflect on their own performance in this lesson: “What did you do well in this lesson? What are the deficiencies? What should you improve in the next study?” For example, some students may reflect that they are not fluent in oral expression, some students may reflect that they have difficulty in organizing writing ideas, and some students may reflect that they have not mastered some core words proficiently. The teacher affirms the students’ reflective attitude, and gives targeted suggestions for different deficiencies: for students with unfluent oral expression, suggest them to practice more in daily life; for students with difficulty in writing ideas, suggest them to list an outline before writing; for students who are not proficient in vocabulary, suggest them to strengthen memory through more reading and writing. Design Intention: Letting students summarize independently can help them sort out the knowledge system of this lesson, deepen their understanding and memory of the learning content, and cultivate their ability to summarize and sort out. Guiding students to reflect on their own performance can help them clearly understand their own strengths and weaknesses, establish a correct learning attitude, and put forward targeted improvement measures, which is conducive to the improvement of their learning ability and the formation of good learning habits. 1 / 1 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
