This is OpenCourseWare. Computer Science E-1 is a course at Harvard Extension School. E-1 isn't so much about computer science as it is about technology and how it all works. Most every student who takes this class uses computers every day but doesn't necessarily understand what's going on underneath the hood (or, in some cases, is outright scared!). All students exit this more comfortable with computers and the Internet. Even if you are not a student at Harvard, you are welcome to "take" this course via computerscience1.tv by following along via the Internet. (The course's own website is at www.computerscience1.net.) Available at left are videos of lectures along with PDFs of problem sets. Sample solutions to the latter are not available, but if you have questions or would like to discuss the material with others, do join the course's Google Group. If you're a teacher, you are welcome to adopt or adapt these materials for your own course, per the license. If you'd like to take this course for real (on Harvard's campus or via the Internet) in order to receive feedback on work, grades, and a transcript, the course will next be offered through Harvard Extension School in Fall 2011. You can register online as of August 2011.
