CSE 199: How the Internet Works

Fall 2016 (8/29/2016–12/19/2016)
Enrollment: 440

Retrospective

We’re preparing a series of blog posts about the challenge of flipping a large course like this one:

  1. Part 1: Logistics

  2. Part 2: Activities (Planned)

  3. Part 3: Online Videos (Planned)

Greg Bunyea and Heeba Kariapper have also been mining the evaluations to learn the lessons of our initial experience and improve the course in future iterations. They prepared this poster summarizing some of our findings:

Full quantitative and qualitative evaluation results are here. Given that this was the first time that the course was offered and the video content, activities, approach, and staff were all new, we were fairly satisfied with these results. The course will definitely improve the next time it is offered, thanks in part to the excellent feedback provided by this year’s students.

Summary

The internet is changing every aspect of our lives, including how we communicate, learn, navigate, organize, work, play, and love. The internet also represents a crowning achievement of computing: a single system uniting hardware and software, theory and implementation, standards and innovation, engineering and science, protests that topple governments and stupid cat videos. This course provides an overview of how the internet works by describing everything required to answer a single search query. Along with its technologies, we will delve into the internet’s past and future, policy challenges, and societal implications. The course is targeted at a general audience, but because the internet reflects contributions from many areas of computer science and computer engineering, it also provides a good overview for potential majors. Familiarity with the web and access to a personal computer are assumed, but no technical background is required.

Structure and Approach

The course is broken into 15 concept units, with one scheduled per week. Instead of being delivered in lecture, content is all delivered online through a content library containing a large number of short videos totaling about one hour of required video content per week for students to review outside of class. Half of that will be assigned for the first meeting (Monday) and half for the second meeting (Wednesday). Individual videos will be limited to 5 m in length, and so the 60 m of per-week video will be spread across at least 12 short videos.

Initially all of the videos will be recorded by the instructor, but over time those initial explanations will be augmented with contributions from faculty, students and alumni. Engaging faculty in the content helps provide students with an introduction to the Computer Science and Engineering department as well as allow experts to speak on topics they know best. Engaging students in the process through an assignment helps ensure that the content library continues to grow and may provide better or alternative explanations. Engaging alumni in the process will help connect students with both local and remote alums working in relevant areas. Videos will also be included from external sources as appropriate. Classroom time is reused for participation-graded group activities that reinforce that week’s material (Monday), for Q&A based on questions about the video content added and voted on by students online (Wednesday), and to allow students to complete graded weekly homework assignments (Friday recitation). Please see the internet-class project page for more details and motivation for this new approach.

Videos

Course content is being prerecorded in five-minute videos made available to students on YouTube.
