Wiki

The class web site is a wiki, as in Wikipedia - meaning that anyone can and is welcome to edit almost anything and in particular, students can post notes, comments, pictures, whatever. Some rules, though -

  • This wiki is a part of my (Dror's) academic web page. All postings on it must be class-related (or related to one of the other projects I'm involved with).
  • You must login to edit. To get an account, email me your preferred login name, your real name and your email address if different from the address you are writing from.
  • Criticism is fine, but no insults or foul language, please.
  • I (Dror) will allow myself to exercise editorial control, when necessary.
  • The titles of all pages related to this class should begin with "10-1100/" or with "10-1100-", just like the title of this page.
  • Some further editing help is available at Help:Contents.

Marking Scheme

There will be one term test (25% of the total grade) and a final exam (50%), as well as about 5 homework assignments (25%).

The Term Test

A term test will take place in class on Tuesday October 26th, 10-12. If you missed the term test for a valid reason, the weight of your problem sets will increase to 35% and the weight of your final exam to 65%.

Homework

Assignments will be posted on the course web page and distributed in class (usually on Tuesdays) approximately on the weeks shown in the class timeline. They will be due about two weeks later and they will be (at least partially) marked by the TA. In computing the homework grade, your single worst assignments will not count. I encourage you to discuss the assignments with other students or even browse the web, so long as you do at least some of the thinking on your own and you write up your own solutions.

Good Deeds

Students will be able to earn up to 25 "good deeds" points throughout the year for doing services to the class as a whole. There is no pre-set system for awarding these points, but the following will definitely count:

  • Drawing a beautiful picture to illustrate a point discussed in class and posting it on this site.
  • Taking class notes in nice handwriting, scanning them and posting them here.
  • Typing up or formatting somebody else's class notes, correcting them or expanding them in any way.
  • Writing an essay on expanding on anything mentioned in class and posting it here; correcting or expanding somebody else's article.
  • Doing anything on our 10-1100/To do list.
  • Any other service to the class as a whole.

Good deed points will count towards your final grade! If you got n of those, they are solidly yours and the above formula for the final grade will only be applied to the remaining 100-n points. So if you got 25 good deed points (say) and your final grade is 80, I will report your grade as 25+80(100-25)/100=85. Yet you can get an overall 100 even without doing a single good deed.

Important. For your good deeds to count, you must do them under your own name. So you must set up an account for yourself on this wiki and you must use it whenever you edit something. I will periodically check Recent changes to assign good deeds credits. Those credits will be made public (good deeds are public as a whole) towards the end of the course, at 10-1100/Register of Good Deeds.

Class Photo

To help me learn your names, I will take a class photo on Tuesday of the third week of classes. I will post the picture on the class' web site and you will be required to send me an email and identify yourself in the picture or to identify yourself on the Class Photo page of this wiki.
