CS 101 Today’s class will start 5 minutes late

CS 101 Introduction to Computer Science Aaron Bloomfield University of Virginia Spring 2007

3 Who we are Aaron Bloomfield: CS 101 Office: Olsson 228D Office hours will be posted on the website Michele Co: CS 101-E Office: Olsson 228A Office hours will be posted on the website

4 Who they are Both instructors also accept appointments We have 16 undergraduate teaching assistants And 1 graduate teaching assistant Their information and hours will be posted on the website

5 What this course is An introduction to programming using Java An introduction to theoretical problems in computer science We’ll start seeing these next time

6 What this course is not We do not talk about (in any depth): Applications of computing Other programming languages (C, C++, Matlab, etc.) History of computing (well, not much) How to use Microsoft office or create a web page

7 Course objectives Understand fundamentals of programming such as variables, conditional and iterative execution, methods, etc. Understand fundamentals of object-oriented programming, including defining classes, invoking methods, using class libraries, etc. Gain exposure to the important topics and principles of software development. Have the ability to write computer programs to solve specified problems. Be able to use a software development environment to create, debug, and run programs.

8 Honor Policy Honor Policy: The University of Virginia Honor Policy is in effect in this class. As a student in the course you also agree to follow the following principles. Unless otherwise specified, the only allowed collaboration for the homeworks and labs is the discussion of ideas; no collaboration is allowed on the exams and lab quizzes. No code or solutions are to be distributed to other students either electronically (i.e. ) or on paper. If you are looking at another student's code, you are in violation of this honor policy. Unless otherwise noted, exams and individual assignments are pledged: you promise that you have neither given nor received unauthorized help. When there is doubt regarding the honorability of an action, you will ask before doing it.

9 Honor Policy Honor Policy: The University of Virginia Honor Policy is in effect in this class. As a student in the course you also agree to follow the following principles. You are not allowed to describe problems on an exam or quiz 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. You are not allowed to debug your fellow student's code – there is ample teaching assistant support, and they can help debug code. This will be discussed in more detail once we start getting into writing (and debugging) Java programs. You may not use another students 'clicker' during lecture (we will be discussing clickers shortly).

10 Honor Policy If you find yourself looking at somebody else's code, and doing such was not explicitly allowed, then you are in violation of this policy! Any honor violation or cheating will be referred to the honor committee, and will result in an immediate failure for the course, regardless of the outcome of the honor trial or your other grades. No exceptions!

11 Website At The syllabus is there (with most of the info in this slide set) And all the lecture notes I will try to post all slide sets on the website the night before lecture But will probably be editing them that day Don’t bother writing down what’s on the slides! There will also be videos of 101 lectures

12 Textbook Starting Out with Java 5 from Control Structures to Objects Tony Gaddis We’ll be covering the first 6 chapters and chapters 8 and 9 This is not the same textbook that was used last semester!

13 Clickers These are RF “remote controls” Allow me to ask questions during class and get responses from everybody Very useful in large lecture halls… The bookstore has them (or will shortly) It is required: there will be a grade penalty if you do not get one

14 Keeping the class interesting Humor breaks Actually helps with attention span! Not surprisingly, most of it will be computer humor!

15 Motivational posters

16 Today’s demotivators

17 Grading criteria 10% – Laboratory participation However, if you miss more than 2 labs, you are subject to failure for the course More on this in a bit… 10% – Laboratory programming quizzes 30% – Homework assignments 30% – Midterms 21 February, 28 March, 25 April 20% – Final exam Scheduled time is Friday, 4 May from 7 pm. to 10 pm We will discuss conflicts as the semester progresses APMA 310, MATH 111, 114, 121, and 122, and STAT 110 Will be following the standard 10-point curve scale

18 Grades All grades will be kept online Viewing your grades will be gone over in the first lab All electronically submitted assignments (labs, HWs, lab quizzes) will be graded electronically They are still graded by a human, of course You will receive an about your grade Only the exams will be graded via paper

19 Grading critera We reserve the right to modify the weighting, especially if attendance drops off significantly Any such change will be announced in lecture

20 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 Regrades must be submitted within 10 (ten) days More on regrades in the first lab We reserve the right to possibly institute a “penalty” on “whiny” regrades

21 Homeworks These are programming homeworks We estimate 9 or so of them Are due at 10 a.m. on Friday Late policy: 1 second late to 24 hours late: -25% 24 hours and 1 second late: -100%

22 Labs Will have one each week Total of 11 (or so) 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 show up to a different lab section without permission, it counts as missing that lab There ARE 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 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

23 Lab scheduling problems I expect about some students will switch into CS 101-E Using last spring semester as a guide That will free up space in all the lab sections I then have to course action in the lab section 10 people We will get everybody registered for a lab section that fits their schedule If you are not registered for a lab section this week, you can go to any lab But only if you aren’t registered for any lab section!

24 Exams There will be three midterms, all pledged 21 February, 28 March, 25 April (all are Wednesdays) There will be three lab quizzes, all pledged During lab sections the week of the midterms The tests are going to be hard! Final exam Scheduled time is Friday, 4 May from 7 pm. to 10 pm We will discuss conflicts as the semester progresses APMA 310, MATH 111, 114, 121, and 122, and STAT 110

25 Home directory service All assignments and lab files must be kept on your home directory

26 My philosophy: hard but fair Fairness is a challenge in a class of 375 students If you feel something is not fair, you need to let me know I will do my best to correct it If you think that this course is not hard, let me know I will do my best to correct it

27 Who to contact I am not always the best person I easily get inundated with s, as I have hundreds of students The TAs can often answer a question just as easily as I can, and much quicker There will be a dedicated graduate TA for grading issues Any administrative requests should be ed to not the instructors or TAs Lab section switches, homework questions, etc. Anything that does not need to be answered by the instructors

28 Office hours Office hours will be posted on the website Note that changes to an individual week will be posted there as well Please check it before you head off to office hours! There will be a lot of TA office hours We expect to provide over 50 office hours during a given week Please utilize them!!!

29 Feedback It’s a very good thing! Feel free to leave us feedback 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…

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

31 Sections CS 101 Students have little or no programming experience Mandatory scheduled closed labs Meets three times a week (M/W/F 3:00-3:50) CS 101-E Students with programming experience Open labs that are to be completed by a scheduled time Meets two times a week (M/W 2:00-3:15) CS 101-X Is being run separately from 101/101-E 101 & 101-E students take same quizzes and tests, and do the same assignments The 10-point curve is the same for everybody So helping your fellow students out does not hurt you

32 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 Labs due 8:30 p.m. on Sunday Optional lab session for 101-E students Sunday at 5 p.m. Pace through the textbook is the same 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 Thus, you know the basics of programming You will need to sign a pledge stating this You did not get a 4 or a 5 on the AB level AP computer science exam, or a 5 on the A level AP exam

33 Should you be in 101-E? If you have had a semester’s worth of programming, then yes Stay to the end of this lecture, then start going to the other section next time Meets in MEC 205

34 End of lecture on 17 January 2007
