Synopsis
This course is all about understanding: understanding what's going on inside your computer when you flip on the switch, why tech support has you constantly rebooting your computer, how everything you do on the Internet can be watched by others, and how your computer can become infected with a worm just by turning it on. In this course we demystify computers and the Internet, along with their jargon, so that students understand not only what they can do with each but also how it all works and why. Students leave this course armed with a new vocabulary and equipped for further exploration of computers and the Internet. Topics include hardware, software, the Internet, multimedia, security, website development, programming, and dotcoms. Through optional hands-on sections and workshops, local students have opportunities to dissect as well as upgrade a computer with additional hardware, search the Internet more effectively, build a wireless network, create digital images, eradicate spyware, and design webpages. Problem sets offer online students similar opportunities. This course is designed both for those with little, if any, computer experience and for those who use a computer every day.
Expectations
You are expected to attend or watch all lectures, complete nine problem sets, take two exams, and produce a final project.
Grades
Your final grade will be determined as follows.

Books
No books are required for this course. However, we do recommend that you procure a set of four books; we offer you a choice of two such sets. A schedule of recommended readings from each set is provided in this document's discussion of lectures. The first set is designed for true beginners—students relatively unfamiliar or uncomfortable with computers and the Internet. The second set is designed for students more savvy with computers the Internet. Both sets cover much of the course's material; the second set, however, provides additional technical detail which may appeal to students eager for additional challenge.

Sections
Sections provide local students with opportunities to work hands-on with computers and the Internet with a teaching fellow by their side. Some sections may, like lectures, be recorded, albeit in audio-only format. Sections take place most weeks during the term. During the course's first lecture, local students sign up for a specific section (i.e., day, time, and location). Sections begin meeting following the second lecture. Distant students unable to travel to campus cannot enjoy these opportunities to work hands-on with computers and the Internet with a teaching fellow. But this course is as conceptual as it is practical. It is designed to arm local and distant students alike with a new vocabulary and to equip both for further exploration of computers and the Internet. A schedule of sections follows.
Section 1: Dissecting a PC
27 September 2006 – 3 October 2006 Section 2: Upgrading a PC 4 October 2006 – 10 October 2006 Section 3: Exploring the Internet 11 October 2006 – 17 October 2006 Section 4: Treasure Hunting 18 October – 24 October 2006 Section 5: Building and Configuring a LAN and WLAN 25 October 2006 – 31 October 2006 Section 6: Designing GIFs, JPEGs, and PNGs 1 November 2006 – 7 November 2006 Section 7: TF's Choice 8 November 2006 – 14 November 2006 Section 8: Disinfecting a PC 15 November 2006 – 21 November 2006 Section 9: Building Websites with XHTML 29 November 2006 – 5 December 2006 Section 10: Enhancing Websites with CSS 6 December 2006 – 12 December 2006 Section 11: Programming with Scratch 13 December 2006 – 19 December 2006 Section 12: Working on Final Projects 3 January 2007 – 9 January 2007 Section 13: Exciting Conclusion 10 January 2007 – 16 January 2007
Workshops
Mastering computers takes time. Although weekly sections afford local students the opportunity for guided exploration, there is always more to learn. To supplement weekly section activities, then, we offer workshops on various topics on most weekends during the term. Some workshops may, like lectures, be recorded. Workshops' locations will be announced. Attendance at these workshops is optional but encouraged. Distant students unable to travel to campus cannot enjoy these opportunities to work hands-on with computers and the Internet with the teaching fellows. But this course is as conceptual as it is practical. It is designed to arm local and distant students alike with a new vocabulary and to equip both for further exploration of computer science. A schedule of workshops follows.

Videos of the Week
In addition to videos of lectures, the course will also release on most Wednesdays a volume of "videos of the week," bite-sized segments produced by the staff on topics related to the most recent lecture. These videos will be available via podcast (for download to iTunes and iPods) and via the course's website in Flash and QuickTime formats.
Problem Sets
Problem sets will be distributed most weeks and be due two or more weeks later. Problem sets must be submitted electronically via the dropboxes on the course's website unless a problem set permits submission on paper. Extensions for problem sets will not be granted, except in cases of emergency. Technical difficulties will not constitute emergencies. Problem sets submitted late without extension will be penalized as follows: submissions up to one hour late will incur a penalty of 5%; submissions up to two hours late will incur a penalty of 10%; submissions up to three hours late will incur a penalty of 25%; submissions up to four hours late will incur a penalty of 50%; submissions more than four hours late will incur a penalty of 100%. Lateness of submissions will be determined by server-side timestamps. When computing your final grade, we will drop your lowest score. Be aware that many questions in problem sets require Internet access, some problem sets may require (of students not taking the course via the Internet) a trip to campus, and one problem set will require a trip to a computer store local to you. A schedule of problem sets follows.

Exams
This course has two, 60-minute exams. The first exam will take place in lieu of the first hour of lecture on Wednesday, 25 October 2006, and will cover lecture topics from Wednesday, 22 September 2006 through Wednesday, 18 October 2006. The second exam will take place in lieu of the first hour of lecture on Wednesday, 13 December 2006, and will cover lecture topics from Wednesday, 1 November 2006 through Wednesday, 6 December 2006. These exams will begin promptly at 5:30 P.M. ET. Each exam will be followed by a 60-minute lecture. Distant students who live outside of New England and cannot travel to campus for an exam are required to find a school local to them that is willing to administer that exam to them in a secure fashion. The Extension School's Registrar will handle the logistics of sending the exam to that school and retrieving it once taken. However, all such students are required to contact their teaching fellow regarding these logistics no fewer than four weeks prior to an exam's date. Moreover, they are required to complete and submit the form available at the address below at least two weeks prior to each exam.
Review Sessions
On Saturday, 21 October 2006, from 11:00 A.M. ET until 1:00 P.M. ET, the teaching fellows will hold a review session for the first exam. On Saturday, 9 December 2006, from 11:00 A.M. ET until 1:00 P.M. ET, they will hold a review session for the second exam. The locations of these review sessions will be announced. Attendance at these review sessions is optional but encouraged.
Final Project
This course requires that you produce a final project in the form of a website with a prescribed set of features. The final project involves two parts. The first part, due by 5:30 P.M. ET on Wednesday, 29 November 2006, requires a written proposal for your project's content. The second part, due by 9:35 P.M. ET on Monday, 22 January 2007, requires actual production of your project. Extensions for the final project will not be granted. Technical difficulties will not constitute emergencies. Final projects submitted late will be penalized as follows: submissions up to one hour late will incur a penalty of 5%; submissions up to two hours late will incur a penalty of 10%; submissions up to three hours late will incur a penalty of 25%; submissions up to four hours late will incur a penalty of 50%; submissions more than four hours late will incur a penalty of 100%. Lateness of submissions will be determined by files' timestamps. Guidelines for the final project will be distributed on Wednesday, 1 November 2006.
Staff's Picks
Becoming a computer person (read: nerd) doesn't happen overnight. But certain movies can help. In fact, watch any of the staff's picks listed on the course's website in its entirety during this semester, write a review of at least 200 words, email your review to cscie1@fas.harvard.edu, and you'll earn five points of extra credit on the most recently due problem set! Be sure your review includes a thumb's up or down! And be sure to explain how the movie's content relates to E-1! You may watch as many of these picks as you wish during the term, but you may submit no more than one review per problem set. You are welcome to watch picks with other students, but each student must submit his or her own review. Look for these picks at your local library or video store, but don't forget such sites as Blockbuster.com and Netflix.com!
Distance Education
If you are taking this course via the Internet, realize that it is our intention that you be as much a part of this course as are students taking the course on campus. However, given the distance between us, we cannot see the occasional perplexed look on your face. And we can't see you raising your hand. So, we ask that you help us help you as much as possible. Please do not ever hesitate to drop us a note, give us a call, or request a call. Though we may never shake hands, we would like very much to get to know you too.
Academic Honesty
All work that you do toward fulfillment of this course's expectations must be your own. Viewing or copying another individual's work (even if published in a world-accessible directory) or lifting material from a book, magazine, website, or other publication—even in part—and presenting said matter as your own constitutes academic dishonesty, as does showing or giving your work, even in part, to another student. Similarly is dual submission academic dishonesty: you may not submit the same or similar work both to this class and to another. Similarly is submitting for extra credit a review of a pick that you have not watched in its entirety during this semester academic dishonesty. All forms of cheating will be dealt with harshly. You are welcome to discuss course material with others in order to better understand that material. However, you must do all problem sets, the exams, and the final project on your own. Contact me or a teaching fellow for help with a specific question on a problem set, an exam, or the final project.
Platforms
This course is designed to be largely independent of particular computing platforms: it does not matter if you are a user of Linux, Mac OS, or Windows. Almost all of the software taught and used by this course is available for all three platforms in some form.
Inclement Weather
In the event of inclement weather, you may call the Extension School's general information line at (617) 495-4024 or the Harvard University Newsline at (617) 496-6397 to find out whether a class has been cancelled. Alternatively, you may visit the course's website or the address below. Announcements will also be broadcast on local radio stations WKRO-AM (680 kHz), WBZ-AM (1030 kHz), WBUR-FM (90.9 MHz), and WCRB-FM (102.5 MHz) as well as on local television stations WBZ (channel 4), WCVB (channel 5), and WHDH (channel 7). You are advised to consult more than one of these sources, lest one or more not be current.
Noncredit
If you are not taking this course for credit, you are not expected to submit problem sets, take the exams, or produce a final project. However, all of the work in this course is designed to facilitate your comprehension and retention of lecture and required reading materials. Consequently, you are encouraged to complete as much of the work as possible. In return, the staff will correct and comment on any work that you submit. |
