1 CS 101 Todays class will begin about 5 minutes late

2 CS 101 Introduction to Computer Science Aaron Bloomfield University of Virginia

3 Instructors –Aaron Bloomfield: CS 101 Office: Olsson 228D Hours: M 3:30-4:30, W/F 11-noon Email: –David Luebke: CS 101-E Office: Olsson 219 Hours: Tu/Th 10:30-noon Email: Both instructors also accept appointments Other course personnel (TAs) will be posted on the website shortly

4 What this course is An introduction to programming using Java

5 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 –How to use Microsoft office or create a web page

6 Objectives Understand fundamentals of programming such as variables, conditional and iterative execution, methods, etc. Understand fundamentals of object-oriented programming in Java, including defining classes, invoking methods, using class libraries, etc. Be aware of the important topics and principles of software development. Have the ability to write a computer program to solve specified problems. Be able to use the Java SDK environment to create, debug and run simple Java programs.

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 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. Unless otherwise noted, exams and individual assignments will be pledged that you have neither given or received unauthorized help.

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

10 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 Dont bother writing down whats on the slides!

11 Text Java 5.0 Program Design, McGraw-Hil. –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 website The bookstore does currently have copies

12 Textbook versions

13 CodeLab license Dont throw it out!

14 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 September, 18 October, 16 November 20% – Final exam –Scheduled time is Monday, 12 December from 7 pm to 10 pm NOT on Saturday –We will discuss conflicts as the semester progresses (APMA 310 and ECON 201) Average grade will be at least a B-

15 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 e-mail about your grade Only the exams will be graded via paper

16 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

17 Keeping the class interesting Like many intro courses, this course does not really show why CS is a fascinating field –Ill be bringing in guest lecturers to give short (5 minute) talks about why they like CS At the beginning of lecture Humor breaks –Actually helps with attention span! –Not surprisingly, most of it will be computer humor!

18 18 Motivational posters…

19 Homeworks There are two types of homeworks: Programming homeworks –a.k.a. J homeworks –6-7 of them CodeLab homeworks –Via –a.k.a. C homeworks –An online service –6-8 of them –All the CodeLab problems will count as one J homework –We will go over CodeLab in a future class

20 Labs Will have one each week –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 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 dont 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

21 Lab scheduling problems I expect about 25 students will switch into CS 101-E –Using last fall semester as a guide That will free up space in all the lab sections If you are not registered for a lab section this week, you can go to any lab –But only if you arent registered for any lab section! We will get everybody registered for a lab section that fits their schedule

22 Exams There will be three midterms, all pledged –21 September, 18 October, 16 November There will be three lab quizzes, all pledged –During lab sections the week of the midterms Final exam –Scheduled time is Monday, 12 December from 7 pm. to 10 pm NOT on Saturday –We will discuss conflicts as the semester progresses (APMA 310 and ECON 201) All exams are open book

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

24 Fairness A difficult thing in a class of 150 students If you feel something is not fair, you need to let me know –I will do my best to correct it

25 Who to contact I am not always the best person –I easily get inundated with emails, as I have 150 students –The TAs can often answer a question just as easily as I can, and much quicker Office hours will be posted on the website

26 Feedback Its 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 Its hard for the instructors to know what the students think of the course…

27 Learning the material There are a number of ways we provide to help you learn the material –Lecture –Slides on the website –Programming homeworks –CodeLab 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

28 Sections CS 101 –Students have little or no programming experience –Mandatory scheduled closed labs CS 101-E –Students with programming experience –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 –CS 101 students hate this policy…

29 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 –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 The following is assumed for students in 101-E –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)

30 Should you be in 101-E? If you have had a semesters worth of programming, then yes Stay to the end of this lecture, then start going to the other section next time –Meets in OLS 009
