Lesson4.0 unit 4 the internet and global impact
- 1. L.O: STUDENTS WILL LEARN ABOUT THE INTERNET AND ITS GLOBAL IMPACT. DO NOW: What is “The Internet”?
- 2. The Internet is the global system of interconnected computer networks that use the Internet protocol suite (“IP addresses”) to link devices worldwide. The internet is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The internet is private computers linked to public computers linked to college/university computers linked to business computers linked to government computers….
- 3. In this unit: • We will learn the structure of the internet. • We will learn about the protocols that run the internet. • We will learn about the implications of internet technology. • We will learn how the internet and its systems have had a profound impact on society.
- 4. Also…. • You will learn how the internet operates. • You will study the characteristics of the internet and the systems built on it. • Last, you will analyze concerns such as cybersecurity
- 5. Our programming labs will focus on: Number Bases, Binary Data, Network Protocols, Cybersecurity
- 6. This is 151
- 7. You will learn what this means
- 8. Note: • We will be seeing several videos from code.org included in this unit. If you have difficulty accessing the videos, you can use this link: • https://code.org/educate/resources/videos.
- 9. The Social Implications labs will focus on: Censorship and Computing around the World
- 10. We will focus on Big Ideas 2 and 6. • The primary focus of this unit is the Internet (Big Idea 6). • Students learn about the power of the fundamental abstractions (Big Idea 2) of the Internet including the two most essential protocols: • IP, which builds one Internet out of a vast collection of local networks; • and TCP, which allows the Internet to function reliably despite the lack of reliability of the physical infrastructure. • You will also learn how the hierarchies of domain names and IP addresses make scalability possible.
- 11. Computational Thinking Practices P1, P3, P5, P6 You will learn to: • identify and describe the abstractions (P3) of the Internet, • continue to collaborate (P6) as they pair program, • and communicate (P5) as they connect computing (P1) to society in the Social Implications labs.
- 12. Time permitting and also on your own we will watch several edX BJC Videos
- 13. The following are our student labs: • Lab 1: Number Representation • 3-6 days (120-240 minutes) for required pages • Lab 2: Reliable Communication • 2-3 days (55-110 minutes) for required pages • Lab 3: Communication Protocols • 2-4 days (60-170 minutes) • Lab 4: Cybersecurity • 1-3 days (45-90 minutes) for required pages • Lab 5: Censorship and Computing around the World • 3-4 days (150-200 minutes)
Editor's Notes
- Purpose Programming Focus: Number Bases, Binary Data, Network Protocols, Cybersecurity Unit 4 addresses the structure of the Internet and the various protocols on which it runs and the implications of this technology to society. From the AP CSP Framework: "The Internet pervades modern computing. The Internet and the systems built on it have had a profound impact on society. Computer networks support communication and collaboration. The principles of systems and networks that helped enable the Internet are also critical in the implementation of computational solutions. Students in this course gain insight into how the Internet operates, study characteristics of the Internet and systems built on it, and analyze important concerns such as cybersecurity." Unit 4 addresses these ideas.

- Social Implications Focus: Censorship and Computing around the World Lab 5: Censorship and Computing around the World asks students to first consider what rules perhaps ought to exist regarding behavior or content on the Internet. They use the Blown to Bits reading and what they've learned about the Internet throughout this unit to discuss the challenges of regulating the Internet. In this Lab, students will also look at ways that countries (including the United States) approach regulation and censorship of online content and will also examine statistics about Internet usage around the world. There is a lot of reading in this unit. Mix it up to keep students engaged. Encourage students to take turns reading in small groups or as a class, or consider assigning different teams to the various pages of the lab and have each team present their section to the class. Choose a strategy that will work for your group of students.
- Big Ideas 2, 6 The primary focus of this unit is the Internet (Big Idea 6). Students learn about the power of the fundamental abstractions (Big Idea 2) of the Internet including the two most essential protocols: IP, which builds one Internet out of a vast collection of local networks; and TCP, which allows the Internet to function reliably despite the lack of reliability of the physical infrastructure. Students also learn how the hierarchies of domain names and IP addresses make scalability possible.
- Computational Thinking Practices P1, P3, P5, P6 Students learn to identify and describe the abstractions (P3) of the Internet, continue to collaborate (P6) as they pair program, and communicate (P5) as they connect computing (P1) to society in the Social Implications labs.
- Assessment: A Divide-And-Conquer Approach The Internet is vast and ever-evolving, so it is not an easy task to cover it in a single unit. A possible approach is a divide-and-conquer class project. Each student, perhaps with a partner, will prepare a 5-minute presentation on a particular topic of interest, drawn from the AP CSP standards. For more information on this pedagogy click here.
