Today, we are going to focus on Assessing Your Progress in Unit 3 The Internet. This is an important part as it helps us see how much we've learned and what we still need to work on in this unit about the Internet. I. Introduction Teacher: First, let's start with a little review. I want you all to think back on what we've learned in Unit 3. Can anyone share one key thing about the Internet that we discussed? Raise your hands. Student 1: We learned about the different uses of the Internet, like for communication and getting information. Teacher: Great! That's very true. The Internet has indeed become a powerful tool for communication, whether it's through emails, social media, or video calls. And it's a vast source of information, with search engines helping us find almost anything we want to know. Anyone else? Student 2: We also talked about the problems on the Internet, such as cyberbullying and privacy issues. Teacher: Excellent point! The Internet isn't all good. There are real problems like cyberbullying, where people are mean to others online, and privacy issues, with our personal information at risk. These are important aspects we explored in this unit. Now, let's move on to today's main tasks, which will help us assess how well we've grasped these concepts and the language related to the Internet. II. Vocabulary Review Teacher: In this part, we are going to review some key vocabulary from the unit. I have a set of sentences here. On your worksheets, you'll see blanks in these sentences. I want you to choose the correct words from the word bank and fill in the blanks with the appropriate form. Let's look at the first sentence together. "The ______ of the new app made it very popular among young people." Now, look at the word bank. Which word do you think fits here? And remember, you might need to change the form of the word. Student 3: I think it's "function". The sentence should be "The functions of the new app made it very popular among young people." Teacher: Perfect! You are right. Here, "function" is used as a noun, and since we are talking about multiple functions that made the app popular, we use the plural form. Now, let's move on to the second sentence. "He likes to ______ with his friends on the Internet every evening." Student 4: It's "chat". He likes to chat with his friends on the Internet every evening. Teacher: Correct. "Chat" is a verb here, and in the infinitive form after "likes to". Let's continue with the rest of the sentences on your worksheets. Work on them for a few minutes, and then we'll check the answers together. (a few minutes later) Teacher: Okay, let's check the answers. For the third sentence, "The company is working hard to improve the ______ of its website." Student 5: It's "design". The company is working hard to improve the design of its website. Teacher: Right. "Design" is a noun in this context. Now, the fourth sentence. "She ______ foolishly when she shared her personal information online." Student 6: It should be "behaved". She behaved foolishly when she shared her personal information online. Teacher: Excellent. "Behave" is used as a verb in the past tense here. Now, let's talk about some of these words in more detail. Take "function". We know it can be a noun, like in "the functions of an app", but it can also be a verb. For example, "This machine functions well." Can you think of another sentence using "function" as a verb? Student 7: The new software functions differently from the old one. Teacher: Great job! And for "chat", besides being a verb, it can also be a noun. For example, "We had a long chat yesterday." Now, I want you to make a sentence using "chat" as a noun. Student 8: I enjoy our daily chats over coffee. Teacher: Perfect. These words can have different functions in different sentences, and it's important to understand how to use them correctly. III. Grammar Review - Present Perfect Passive Teacher: Now, let's move on to grammar. In this unit, we learned about the present perfect passive. Remember, we use the present perfect passive when we want to focus on the action that has been done to the subject, and the action started in the past and has a connection to the present. I have a passage here on the screen. Read it carefully and then answer the questions that follow. (The passage is shown on the screen: "The Internet has been used by billions of people around the world. It has been developed over many years. Many new technologies have been created to make the Internet faster and more accessible.") Teacher: First question, what is the subject in the first sentence? Student 9: The subject is "The Internet". Teacher: Right. And what is the action being done to the subject? Student 10: The action is "used", and it's in the present perfect passive form "has been used". Teacher: Exactly. Now, why do we use the present perfect passive here? Student 11: Because the action of using the Internet started in the past and is still happening now. Billions of people are still using the Internet. Teacher: Perfect explanation. Now, let's look at the second sentence. What is the subject and the action in the present perfect passive? Student 12: The subject is "It" (referring to the Internet), and the action is "developed", in the form "has been developed". Teacher: Correct. And again, why this form? Student 13: Because the development of the Internet started in the past and has continued until now. It's still evolving. Teacher: Great. Now, I want you to create your own sentences using the present perfect passive related to the Internet. For example, you can think about how the Internet has changed our lives, or what has been done to improve Internet security. Write down two sentences on your worksheets. (a few minutes later) Teacher: Okay, let's share some of your sentences. Who wants to go first? Student 14: Many online courses have been offered by universities to help students learn. Teacher: Wonderful sentence. The subject is "Many online courses", and the action "offered" is in the present perfect passive. The universities started offering these courses in the past, and they are still available now. Another student? Student 15: Internet speed has been increased in many areas to meet people's needs. Teacher: Excellent. Here, "Internet speed" is the subject, and "increased" is the action in the present perfect passive. The action of increasing the speed started in the past and has a present - day result. IV. Reading Comprehension Teacher: Now, we are going to do a reading comprehension activity. I will hand out a short passage about the impact of the Internet on education. Read it carefully and answer the questions on the back of the handout. The passage focuses on how the Internet has changed the way students learn, what new opportunities it has brought, and also some challenges. (Students receive the handouts and start reading) Teacher: While you are reading, look for key information. Highlight important sentences or words that will help you answer the questions. Remember, the questions might ask about details, the main idea, or your understanding of certain concepts in the passage. (after students finish reading) Teacher: Let's start with the first question. "What are the new opportunities the Internet has brought to education according to the passage?" Student 16: The passage says that students can access a lot of educational resources online, like e - books, online courses, and educational videos. They can also learn at their own pace and communicate with teachers and other students from all over the world. Teacher: Very good. You've covered all the main points. Now, the second question. "What are some of the challenges the Internet poses to education?" Student 17: There is too much information on the Internet, and it's hard for students to tell which is reliable. Also, some students might get distracted by non - educational content like games and social media while they are supposed to be studying. Teacher: Correct. These are real challenges in the digital age of education. Now, for the third question, "How does the author think students can make the best use of the Internet for learning?" Student 18: The author suggests that students should learn to filter information, use reliable educational websites, and set a schedule to avoid getting distracted. Teacher: Right. This reading shows us how important it is to not only know about the Internet but also to use it wisely, especially in an educational context. V. Discussion Teacher: Now, let's have a group discussion. I will divide you into groups of four. The topic for discussion is "If you could create a new Internet - related service, what would it be and why?" Think about the problems we have on the Internet or the things that people need but don't have yet. Each group member should share their ideas, and then as a group, come up with the best idea and be ready to share it with the class. (Students are divided into groups and start discussing) (after a few minutes) Teacher: Okay, let's start with Group 1. Share your idea with the class. Group 1 representative: We thought of creating a special app that filters all the information for students. When they search for something related to their studies, the app only shows reliable educational sources. It would save students a lot of time and help them avoid false information. Teacher: That's a very practical and useful idea. How did you come up with this? Group 1 representative: Well, we were talking about the reading we just did, and the problem of too much information on the Internet. We thought this could be a good solution for students. Teacher: Great thinking. Now, Group 2, what's your idea? Group 2 representative: We want to create an online platform where people can exchange skills. For example, if someone is good at painting, they can teach others online, and in return, they can learn something else, like coding, from someone who is an expert in that. Teacher: That's an interesting concept. It promotes learning and sharing among people. Group 3? Group 3 representative: Our idea is to have a virtual reality - based language learning environment. Students can practice speaking with virtual characters from different countries in real - life - like situations. It would make language learning more fun and effective. Teacher: Very creative. This could really enhance the language learning experience. It's great to see all these innovative ideas. It shows that you've really thought about the potential of the Internet and how it can be improved. VI. Writing Teacher: For our last activity today, we are going to do some writing. I want you to write a short paragraph about your own experience with the Internet. You can talk about how it has helped you, any problems you've faced, or what you like or dislike about it. Use the vocabulary and grammar we've reviewed today. Start with an introduction sentence, then give some details, and end with a conclusion sentence. You have 15 minutes to write. (Students start writing) Teacher: While you are writing, make sure your sentences are clear and your ideas are organized. Use proper punctuation and capitalization. If you need to, you can refer back to the vocabulary and grammar we've discussed. (after 15 minutes) Teacher: Okay, let's stop here. Now, I want you to exchange your paragraphs with a partner. Read your partner's paragraph and give them some feedback. You can comment on their ideas, grammar, vocabulary, or anything that can be improved. Then, your partner will do the same for you. (Students exchange paragraphs and give feedback) Teacher: Now, based on the feedback you received, make some changes to your paragraph if needed. You can make it better by adding more details, correcting grammar mistakes, or using more vivid vocabulary. VII. Conclusion Teacher: Class, today we've done a lot of activities to assess our progress in Unit 3 The Internet. We reviewed vocabulary, grammar, did some reading, had a discussion, and did some writing. Through these activities, I hope you've realized how much you've learned about the Internet and also where you might still need to improve. The Internet is an ever - changing and important part of our lives, and learning English related to it will help you communicate better in this digital world. For homework, I want you to read an article about the latest Internet technology and write a short summary of it. This will further enhance your understanding of the topic. That's all for today.
