7. 7 Honor policy The University of Virginia Honor Policy is in effect in this class. As a student in the course you are agreeing to the following principles. When there is doubt regarding the honorability of an action, you will ask before doing it. When there is doubt regarding the honorability of an action, you will ask before doing it. When possible to do so with honor, you will help your fellow classmates learn and improve. When possible to do so with honor, you will help your fellow classmates learn and improve. You will get help from classmates and course staff before succumbing to frustration. Frustration leads to the dark path. You will get help from classmates and course staff before succumbing to frustration. Frustration leads to the dark path. Unless otherwise noted, exams and individual assignments will be pledged that you have neither given or received unauthorized help.

8. 8 Honor policy By default, the only allowed collaboration is the discussion of ideas. No code or solutions are to be distributed to other students either electronically or on paper. You are not allowed to describe problems on an exam to a student who has not taken it yet. You are not allowed to show exam papers to another student or view another student's exam papers while working on an exam. An academic irregularity on any exam may result in failure of the course and be brought to the honor committee. If you have questions on what is allowable, ask!

9. 9 Honor policy Academic irregularities may result in failure of the course and be brought to the honor committee Beware of MOSS

10. 10 Website At http://www.cs.virginia.edu/~cs101 The syllabus is there (with most of the info in this slide set) And all the lecture notes And all the lecture notes All slides will be posted on the website the night before lecture Note that I will probably update the slides Don’t bother writing down what’s on the slides!

11. 11 Text Java Program Design, McGraw-Hill, 2005, ISBN 0072948655. Cohoon and Davidson Cohoon and Davidson Make sure to get the shrink-wrapped version with the CodeLab license! A rough schedule of what we will be covering when is on the webiste

12. 12 Grading criteria 10% – Laboratory participation However, if you miss more than 2 labs, you are subject to failure for the course However, if you miss more than 2 labs, you are subject to failure for the course More on this in a bit… More on this in a bit… 10% – Laboratory programming quizzes 30% – Homework assignments 30% – Midterms 23 February, 23 March, and 20 April. 23 February, 23 March, and 20 April. 20% – Final exam Scheduled time is Monday, 9 May from 7 pm. to 10 pm Scheduled time is Monday, 9 May from 7 pm. to 10 pm NOT on Saturday We will provide the make-up for conflicts (APMA 310 and ECON 201) We will provide the make-up for conflicts (APMA 310 and ECON 201) Average grade will be at least a B-

13. 13 Grades All grades will be kept in the Toolkit grade book All electronically submitted assignments (labs, HWs, lab quizzes) will be graded electronically They are still graded by a human, of course They are still graded by a human, of course You will receive an e-mail about your grade You will receive an e-mail about your grade You will also be able to view your graded assignments online You will also be able to view your graded assignments online More info on this in the first lab Only the exams will be graded via paper

14. 14 Regrades When an assignment is graded, the grading guidelines will be posted If you feel you deserve more credit, you need to submit a regrade Paper-based for the exams, electronically for labs, HWs, and lab quizzes Paper-based for the exams, electronically for labs, HWs, and lab quizzes Regrades must be submitted within 10 (ten) days

15. 15 Homeworks There are two types of homeworks: Programming homeworks a.k.a. “J” homeworks a.k.a. “J” homeworks 6-7 of them 6-7 of them CodeLab homeworks Via http://www.turingscraft.com Via http://www.turingscraft.com a.k.a. “C” homeworks a.k.a. “C” homeworks An online service An online service 6-8 of them 6-8 of them All the CodeLab problems will count as one or two homeworks All the CodeLab problems will count as one or two homeworks

16. 16 Labs Will have one each week Total of 11 throughout the semester Total of 11 throughout the semester Lab attendance is REQUIRED If you miss more than 2 labs, you are subject to course failure for the course If you miss more than 2 labs, you are subject to course failure for the course If you show up to a different lab section without permission, it counts as missing that lab If you show up to a different lab section without permission, it counts as missing that lab No labs this first week No labs this first week Lab grading will be discussed in the first lab If you don’t finish the lab during lab period, you can finish it within the next 24 hours More details on this in the first lab More details on this in the first lab If for a valid reason you are unable to do your lab, there will be a make-up lab on Sunday night, provided that you get permission prior to your scheduled lab

17. 17 Lab scheduling problems I expect 50+ students will switch into CS 101-E Using previous semesters as a guide Using previous semesters as a guide That will free up space in all the labs There is no lab this week, so there is no rush

18. 18 Exams There will be three midterms, all pledged There will be three lab quizzes, all pledged During lab sections During lab sections

19. 19 Home directory service All assignments and lab files must be kept on your home directory http://www.virginia.edu/homedir http://www.virginia.edu/homedir

20. 20 Fairness A difficult thing in a class of 500 students If you feel something is not fair, you need to let me know I will do my best to correct it I will do my best to correct it

21. 21 Who to contact I am not always the best person I easily get inundated with emails, as I have 550 students I easily get inundated with emails, as I have 550 students The TAs can often answer a question just as easily as I can, and much quicker The TAs can often answer a question just as easily as I can, and much quicker Office hours will be posted on the website

22. 22 Feedback It’s a very good thing! Feel free to leave us feedback Can be done anonymously, if you wish Can be done anonymously, if you wish Via the Toolkit or the CS dept website It’s hard for the instructors to know what the students think of the course…

23. 23 Learning the material There are a number of ways we provide to help you learn the material Lecture Lecture Slides on the website Slides on the website Programming homeworks Programming homeworks CodeLab homeworks CodeLab homeworks Labs Labs Textbook Textbook Previous years’ tests Previous years’ tests TAs (during labs or office hours) TAs (during labs or office hours) Professors (office hours) Professors (office hours) Fellow students Fellow students Find what works best for you and use it

24. 24 Sections CS 101 Students have little or no programming experience Students have little or no programming experience Mandatory scheduled closed labs Mandatory scheduled closed labs CS 101E Students with programming experience Students with programming experience Open labs that are to be completed by a scheduled time Open labs that are to be completed by a scheduled time All students take same quizzes and tests, and do the same assignments Course curve is based on the section with the lower average

25. 25 Differences with 101-E Labs are done by all 101-E students on their own time If you miss more than 2, you are still subject to failure If you miss more than 2, you are still subject to failure Labs due 8:30 p.m. on Sunday Labs due 8:30 p.m. on Sunday Lab session for 101-E students Sunday at 7 p.m. Lab session for 101-E students Sunday at 7 p.m. Pace through the textbook is the same They may go through it in more detail, though They may go through it in more detail, though The following is assumed for students in 101-E You have taken a course in programming You have taken a course in programming Thus, you know the basics of programming You did not get a 4 or a 5 on the AP computer science exam (AB level) You did not get a 4 or a 5 on the AP computer science exam (AB level)
