                   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.

                                                                   7
               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!

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

                  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
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!

                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 provide the make-up for conflicts (APMA 310 and ECON
    201)
Average grade will be at least a B-
                                                                   13
                  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
                                                  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
Regrades must be submitted within 10
(ten) days
More on regrades in the first lab
                                               15
Keeping the class interesting
Like many intro courses, this course does
not really show why CS is a fascinating
field
   I’ll be bringing in guest lecturers to give short
    (5 minute) talks about why they like CS
Humor breaks
   Actually helps with attention span!
   Not surprisingly, most of it will be computer
    humor!
                                                   16
Motivational posters…




                        17
                Homeworks
There are two types of homeworks:
Programming homeworks
   a.k.a. “J” homeworks
   6-7 of them
CodeLab homeworks
   Via http://www.turingscraft.com
   a.k.a. “C” homeworks
   An online service
   6-8 of them
   All the CodeLab problems will count as one J
    homework
                                              18
                              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 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
                                                               19
     Lab scheduling problems
I expect 50+ students will switch into CS
101-E
   Using previous semesters as a guide
That will free up space in all the labs
If you are not registered for a lab section
this week, you can go to any lab



                                          20
                   Exams
There will be three midterms, all pledged
There will be three lab quizzes, all pledged
   During lab sections
All exams are open book




                                           21
      Home directory service
All assignments and lab files must be kept
on your home directory
   http://www.virginia.edu/homedir




                                         22
                   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




                                           23
            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




                                               24
                  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…



                                               25
        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
                                            26
                       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…
                                                             27
       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)
                                                            28
