Learning with personal electronic devices. Hung: I'm preparing for a class discussion on personal electronic devices. Do you think smartphones, laptops and tablets are useful for learning? Phong: Definitely. They're the modern devices that have changed the way we learn. Hung: Oh, yeah? I think people use smartphones mostly for communication. Phong: Sure, but smartphones can also be used to take photos or record students’ work, which can be later shared with the class. Hung: That's true. How about laptops? Phong: Oh, they're excellent learning tools, too. You can store information, take notes, write essays and do calculations. Lam: You can also access the Internet, download programmes, and information that can help you understand the material and widen your knowledge. Phong: Right. My laptop, which is a present from my parents, is very useful. I use it for assignments and projects, and for studying English. Hung: I see. How about tablets? Phong: Well, a tablet or a tablet computer is a kind of mobile computer and... Lam: ... it can be used to take notes with a digital pen on a touch screen. A tablet is also perfect for people whose work is to draw and write. Phong: Yes. I agree. A tablet with WiFi has Internet access and is a great tool for looking up information. Hung: Amazing! No wonder that so many people are using these devices. mn giúp mình tóm tắt bài thoại này thành 1 đoạn văn ngắn đầy đủ ý với ạ mai sáng mình kt mất r huhu
