新视野大学英语第三电子教案Book UnitUnit 3 Digital campus Understanding and Learning Overview This unit discusses the pros and cons of the use of new technology in young peoples lives. Young people are the most eager group to use new electronic gadgets. They are also more likely to develop addiction to the Internet and electronic gadgets, which may lead to many undesirable consequences. We hope that students can understand the benefits of the Internet and electronic gadgets and at the same time realize the possible negative effects of obsession with them. Text A emphasizes the positive effects of the electronic gadgets on students studies and lives. We hope students, after reading the text, can answer such questions as why some universities have spent so much money establishing easy access to the Internet, what electronic gadgets are popular on campus, and how these gadgets facilitate their study. We expect students to discuss how the Internet is promoting or hindering their learning, and which teaching method is better, the traditional approach or the multimedia approach. In contrast with Text A, Text B depicts the severe consequences caused by Internet addiction. Through comparison and contrast, students are expected to be fully aware of both the pros and cons of the use of new technology. We would also like them to ask themselves whether they are or were cyber addicts, discuss what causes a person to become a cyber addict, and how they can prevent themselves from becoming Internet-addicted. Meanwhile, students should be encouraged to be masters of science and technology rather than be controlled by them. As to writing styles, Text A is like a news report because it provides some data and cites quotations with sources. Therefore， it sounds more convincing than Text B, which cites indirect quotations without providing sources. Classroom activities may include group discussions, surveys and debating. For example, ask students to interview a few classmates about what kind of teaching and learning style they prefer and discuss their findings in groups, or ask them to debate whether a university should provide Internet access anywhere, anytime. Also, ask students to study the arguments and evidence in the two texts and decide which text is more persuasive and why. Section A College life in the Internet age Background information Smartphones A smartphone is a device with which one can not only make phone calls, but also send and receive email, and edit Office documents. But what makes smartphones so popular is that they can access the web at higher speeds, thanks to the growth of 3G and 4G data networks, as well as the Wi-Fi support. But as the technology is constantly changing, what constitutes a smartphone today may change by next week, next month, or next year. Stay tuned! Detailed study of the text 1.
