Today, we're going to have an exciting Video Time session as part of our exploration of Unit 3 The Internet. Videos are a great way to not only enhance our understanding of the topic but also improve our language skills. We'll be watching some carefully selected videos related to the Internet, and then we'll engage in various activities to analyze and discuss what we've seen. So, let's get started! I. Introduction to the Video Theme (5 minutes) Teacher: First, let's talk a bit about why we're watching videos today. The Internet is such a vast and dynamic topic, and videos can bring it to life in ways that textbooks sometimes can't. They can show us real - life examples, different perspectives, and the latest trends. Today, we'll be focusing on videos that showcase both the positive and negative aspects of the Internet, as well as some of its innovative applications. To set the stage, I want you to think about this question: What is one aspect of the Internet that you find most fascinating or concerning? I'll give you a minute to jot it down in your notebooks, and then we'll share a few responses. (a minute later) Teacher: Okay, let's start sharing. Who wants to go first? Student 1: I find the way the Internet has changed communication fascinating. We can talk to people all over the world instantly. Teacher: That's a great point! The Internet has truly revolutionized communication. It's made the world a much smaller place in terms of connecting with others. Another student? Student 2: I'm concerned about online privacy. There's so much of our personal information on the Internet, and it seems like it's at risk all the time. Teacher: Absolutely. Online privacy is a huge issue in today's digital age. With the amount of data we share online, it's crucial to be aware of how our information is being used. These are exactly the kinds of topics our videos will touch upon. Now, let's move on to the first video. II. First Video - The Internet: A Global Connectivity Tool (10 minutes, including video watching and initial discussion) Teacher: The first video we're going to watch is titled "The Internet: A Global Connectivity Tool." This video will show us how the Internet has connected people from different corners of the globe, enabling the exchange of ideas, cultures, and businesses. As you watch, pay attention to the examples given and how they illustrate the power of the Internet in bringing people together. (The teacher plays the video) Teacher: Okay, the video has ended. Let's start with some initial thoughts. What was one example from the video that really stood out to you about how the Internet connects people globally? Student 3: The part about the online language exchange platforms. People from different countries can practice speaking with each other in real - time. It's amazing how the Internet makes that possible. Teacher: That's a great example. These language exchange platforms break down language barriers and allow for cultural exchange. Another student? Student 4: I liked the story about the small - scale farmers in a remote area who were able to sell their products globally through an e - commerce website. The Internet gave them access to a much larger market. Teacher: Excellent observation. This shows how the Internet can boost economic opportunities even for those in the most remote locations. Now, let's dig a little deeper. How does this kind of global connectivity through the Internet impact our lives on a personal level? Discuss in pairs for a couple of minutes and then we'll share. (a couple of minutes later) Teacher: Let's hear some of your thoughts. What impact does global connectivity have on our personal lives? Student 5: It broadens our horizons. We can learn about different cultures, traditions, and ways of life just by going online. It enriches our knowledge and understanding of the world. Teacher: Very true. The Internet exposes us to a wealth of information from around the world. Another pair? Student 6: It also makes it easier to maintain relationships with friends and family who live far away. We can video - chat and stay updated on each other's lives. Teacher: That's a great point. The Internet has definitely changed the way we maintain long - distance relationships. III. Vocabulary Building from the First Video (10 minutes) Teacher: Now, let's focus on some new vocabulary we encountered in the video. I've selected a few words and phrases that are important to understand the concept of global connectivity through the Internet. On the board, you can see the words: "e - commerce," "online platform," "cross - cultural exchange," and "global marketplace." Let's start with "e - commerce." Can anyone try to define it based on what we saw in the video? Student 7: It's when people buy and sell things online. Like the farmers selling their products on the e - commerce website. Teacher: Perfect! E - commerce, short for electronic commerce, has become a huge part of our lives. We use it for everything from buying clothes to ordering food. Now, what about "online platform"? Student 8: It's like a website or an app where people can do different things. For example, the language exchange platform where people can practice speaking. Teacher: Exactly. Online platforms are digital spaces that enable various activities, whether it's communication, business, or learning. Now, "cross - cultural exchange." What does this mean? Student 9: It's when people from different cultures interact and share their ideas, like when people from different countries use the Internet to talk about their traditions. Teacher: Right. The Internet has made cross - cultural exchange much more accessible. And finally, "global marketplace." Student 10: It's like the whole world as a market. With the Internet, businesses can sell their products to people all over the world, so it's like one big marketplace. Teacher: Great job. Now, I want you to use these words in sentences. Write two sentences for each word in your notebooks. You can use examples from the video or come up with your own. (a few minutes later) Teacher: Let's share some of your sentences. Who wants to start with a sentence using "e - commerce"? Student 11: Many small businesses have thrived because of e - commerce, as they can reach a wider customer base. Teacher: Excellent. Another sentence? Student 12: E - commerce has changed the way we shop, making it more convenient and accessible. Teacher: Great. Now, for "online platform." Student 13: Social media is a popular online platform where people can connect with friends and share their daily lives. Teacher: Perfect. Another one? Student 14: There are various online platforms for learning, such as those that offer free courses on different subjects. Teacher: Good job. Moving on to "cross - cultural exchange." Student 15: The Internet has facilitated cross - cultural exchange by allowing people to participate in online forums and discuss different cultural practices. Teacher: That's a great sentence. Another? Student 16: Cross - cultural exchange through the Internet helps to break down stereotypes and build understanding among different cultures. Teacher: Excellent. And finally, "global marketplace." Student 17: Companies are constantly looking for ways to expand their presence in the global marketplace through innovative online marketing strategies. Teacher: Great. Another? Student 18: The global marketplace enabled by the Internet has led to increased competition among businesses worldwide. Teacher: Well done, everyone. Understanding these vocabulary words will help you better express your thoughts about the Internet and its global impact. IV. Second Video - The Dark Side of the Internet (10 minutes, including video watching and initial discussion) Teacher: Now, we're going to watch a video that shows a different side of the Internet. The video is called "The Dark Side of the Internet." It will focus on some of the negative aspects such as cybercrime, online bullying, and the spread of misinformation. As you watch, take note of the examples given and how they affect individuals and society. (The teacher plays the video) Teacher: The video has ended. Let's start with some initial reactions. What was one of the most concerning issues presented in the video? Student 19: Cybercrime, especially identity theft. It's scary to think that someone can steal your personal information and use it for illegal purposes. Teacher: Absolutely. Identity theft is a major problem in the digital world. Another student? Student 20: Online bullying was really disturbing. The video showed how it can have a serious impact on a person's mental health. Teacher: That's true. Online bullying can be extremely harmful, and it's an issue that we need to be aware of. Now, let's discuss in small groups of three or four. How can we protect ourselves from these negative aspects of the Internet? You have five minutes to discuss, and then we'll come back together and share your ideas. (five minutes later) Teacher: Let's hear some of your group's ideas on how to protect ourselves from the negative aspects of the Internet. Group 1 representative: For cybercrime, we should be careful about what information we share online. Don't click on suspicious links, and use strong passwords. Teacher: Great advice. Being cautious about online information and using proper security measures is crucial. Another group? Group 2 representative: To prevent online bullying, we should be kind to others online and report any bullying behavior we see. Also, parents and schools should educate students about the importance of positive online behavior. Teacher: Excellent points. Creating a positive online environment and having proper reporting mechanisms are essential. V. Analyzing the Contrast between the Two Videos (10 minutes) Teacher: Now, let's take a step back and analyze the contrast between the two videos we've watched. The first one showed the positive side of the Internet as a global connectivity tool, and the second one showed the dark side. In your notebooks, write down at least two major differences between the two aspects of the Internet presented in the videos. Then, we'll share and discuss. (a few minutes later) Teacher: Let's start sharing. What are some of the major differences you noted? Student 21: The first video was about how the Internet brings people together and creates opportunities, while the second one was about how it can harm people and cause problems. Teacher: That's a fundamental difference. The Internet has the potential for both great good and great harm. Another student? Student 22: The positive side focused on things like economic growth and cultural exchange, while the negative side was more about personal safety and the spread of bad information. Teacher: Right. The positive aspects often relate to progress and connection, while the negative aspects are more about risks and threats. Now, let's discuss this as a class. How can we, as Internet users, maximize the positive aspects and minimize the negative aspects? Student 23: We can use the Internet for educational and productive purposes, like taking online courses. And we should be careful about the information we believe and share to avoid spreading misinformation. Teacher: Great thinking. By being purposeful in our Internet use and critical of the information we encounter, we can make better use of the Internet. Another student? Student 24: We can also be part of online communities that promote positive values and avoid those that might lead to negative behavior, like cyberbullying. Teacher: That's a wonderful idea. Choosing the right online communities can have a big impact on our Internet experience. VI. Third Video - Innovative Internet Applications (10 minutes, including video watching and discussion) Teacher: Now, let's end our video session on a more positive and forward - looking note. We're going to watch a video called "Innovative Internet Applications." This video will showcase some of the latest and most creative ways the Internet is being used, from new technologies in healthcare to innovative educational tools. As you watch, think about how these applications can change our future. (The teacher plays the video) Teacher: The video has finished. Let's start discussing. What was one innovative application that you found particularly interesting? Student 25: The use of the Internet in telemedicine. It can bring medical expertise to remote areas where there are few doctors. Teacher: That's a very promising application. Telemedicine has the potential to improve healthcare access for millions of people. Another student? Student 26: The virtual reality - based educational platforms. They make learning more engaging and interactive. Teacher: Right. These new educational tools can enhance the learning experience and make it more fun. Now, I want you to work in pairs and come up with an idea for a new Internet - based application. It can be in any field, such as entertainment, environment, or transportation. You have five minutes to brainstorm, and then we'll share your ideas. (five minutes later) Teacher: Let's hear some of your innovative Internet - based application ideas. Student 27: We thought of an app that can help people reduce their carbon footprint. It would track your daily activities, like transportation and energy use, and give you tips on how to be more environmentally friendly. Teacher: That's a great and timely idea. With the growing concern for the environment, such an app could be very useful. Another pair? Student 28: Our idea is a virtual transportation planner. It would use real - time data from various transportation systems to find the fastest and most cost - effective way to get from one place to another, combining different modes of transport like buses, trains, and rideshares. Teacher: Very creative. This kind of application could make traveling more efficient. VII. Conclusion (5 minutes) Teacher: Class, today's Video Time has been a great exploration of the Internet from different perspectives. We've seen its positive side as a global connectivity tool, its dark side with various risks, and some exciting innovative applications. Through this, I hope you've gained a more comprehensive understanding of the Internet and how it impacts our lives. Remember, the Internet is a powerful tool, but like any tool, it depends on how we use it. We have the responsibility to use it wisely, protect ourselves from its negative aspects, and embrace its potential for good. For homework, I want you to write a short essay about one of the topics we discussed today. You can choose to write about the importance of global connectivity through the Internet, how to combat the negative aspects of the Internet, or your vision for a future Internet - based application. This will help you further reflect on what we've learned. That's all for today.
