Discussion The class forum (Piazza) for all technical questions and bug reports is here: https://piazza.com/class#winter2013/cs124 (sign up)
Email Mail non-technical questions only to cs124-win1213-staff@lists.stanford.edu. We will not reply to email sent to individual staff members. If you have a matter to be discussed privately, please come to office hours, or use cs124-win1213-staff@lists.stanford.edu to make an appointment.

We prefer that most questions are posted on the Piazza Forum - responses tend to be quicker and have a wider audience.

We use the mailing list generated by Axess to convey messages to the class. We will assume that all students read these messages.

Required Work
  • Video Lectures : Each week, we will ask you to watch a set of video lectures (2 to 2.5 hours total). The videos will have some in-video questions embedded in them, which you should answer. You are required to watch the videos, but the embedded quizzes are not counted toward the final grade.
  • Automated Review Quizzes: After watching a week's video lectures, we will ask you to answer an open-notes, open-book review quiz (about 5 questions) on the content that you just learned. Each review quiz may be attempted several times, with a time lag of 10 minutes in between each attempt. The questions, as well as the options for each question, are randomly selected from a larger pool each time you take a quiz. We will take the highest score over all attempts for each quiz. The first two attempts will not be penalized; subsequent attempts will incur a cumulative 20% penalty (e.g., the maximum score possible is 80% on the 3rd attempt and 60% on the 4th attempt). Review Quizzes for each week are due 10:00pm Tuesday of the following week. There are no late days for review quizzes.
  • Class Participation: Since lectures are on-line, the in-class sessions Tuesday and Thursday mornings will be used for problem-solving, reviews, discussions, guest speakers from industry, and presentation of state-of-the-art research. You can get extra credit for class participation by answering questions on the class forum.
  • Homeworks: 7 programming assignments (in Java or Python, your choice). Each assignment is due at 5:00pm on the Friday it is due.
    • Homework Collaboration: You may talk to anybody you want about the assignments and bounce ideas off each other. But you must write the actual homeworks and programs yourself.
    • Late homeworks: You have 4 free late (calendar) days to use on the homeworks. Once these are exhausted, any homework turned in late will be penalized 20% per late day. Each 24 hours or part thereof that a homework is late uses up one full late day.
  • Readings: We will expect you to do a significant amount of textbook reading in this course.
  • Final Exam: Friday Mar 22, 12:15pm-3:15pm
  • Final grade: 56% homeworks, 30% final exam, 9% weekly review quizzes, 5% attendance and participation
