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. e-mail) 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.





When there is doubt regarding the honorability of an action, you will
ask before doing it.
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).

Honor 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!

Website


At http://www.cs.virginia.edu/~cs101
The syllabus is there (with most of the info in this
slide set)


I will try to post all slide sets on the website the
night before lecture


And all the lecture notes
But will probably be editing them that day
Don’t bother writing down what’s on the slides!
10
Things to buy

You need to acquire 4 things for this course





The textbook
A clicker
A clicker license
A CodeLab license
All are discussed here in detail
11
Textbook

Java 5.0 Program
McGraw-Hil.



Design,
Cohoon and Davidson
A rough schedule of what we
will be covering when is on
the website
The bookstore had the wrong
one

The new one should be arriving
shortly, and will cost $113
12
Textbook versions
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 (will) have them shortly
In addition to the physical clicker, you
will also need a license

The license comes with the textbook
14
CodeLab license



An online system we will use later
License comes with the textbook
Don’t throw it out!
15
How to get all of this?

If you buy the shrink-wrapped book in the
bookstore


It comes with both licenses
Then you only need to by the clicker


If you acquire a used textbook



Which the bookstore will also have
You can still get the clicker in the bookstore
The licenses need to be purchased online
Everybody must get all four things (sorry about the
cost!)
16
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


At the beginning of lecture
Humor breaks


Actually helps with attention span!
Not surprisingly, most of it will be computer humor!

Grading criteria

10% – Laboratory participation





10% – Laboratory programming quizzes
30% – Homework assignments
30% – Midterms


However, if you miss more than 2 labs, you are subject to failure for
the course
More on this in a bit…
27 September, 25 October, and 29 November
20% – Final exam

Scheduled time is Thursday, 14 December from 7 pm. to 10 pm



NOT on Friday
We will discuss conflicts as the semester progresses (APMA 310,
ECON 201 (sections 100 and 200), and ECON 401)
Will be following the standard 10-point curve scale
20
Grades

All grades will be kept online


All electronically submitted assignments (labs,
HWs, lab quizzes) will be graded electronically



Viewing your grades will be gone over in the first lab
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
21
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
22
Homeworks


There are two types of homeworks:
Programming homeworks



a.k.a. “J” homeworks, as they use Java
8 of them
CodeLab (a.k.a. “C”) homeworks





Via http://www.turingscraft.com – an online service
This will require purchasing a $20 license (online)
5 (or so) of them this semester
All the CodeLab problems will count as one or two J
homework(s)
We will go over CodeLab in a future class
23
Labs

Will have one each week


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


Total of 11 (or so) throughout the semester
More details on this in the first lab
If for a valid reason you are unable to do your lab, there will be a makeup lab on Sunday night, provided that you get permission prior to your
scheduled lab
24
Lab scheduling problems

I expect about 20 students will switch into CS 101-E



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


Using last fall semester as a guide
But only if you aren’t registered for any lab section!
We will get everybody registered for a lab section that fits
their schedule
25
Exams

There will be three midterms, all pledged


There will be three lab quizzes, all pledged



27 September, 25 October, and 29 November
During lab sections the week of the midterms
The tests are going to be hard!
Final exam

Scheduled time is Thursday, 14 December from 7 pm. to 10 pm


NOT on Friday
We will discuss conflicts as the semester progresses (APMA 310,
ECON 201 (sections 100 and 200), and ECON 401)
26
Home directory service

All assignments and lab files must be kept on your
home directory

My philosophy: hard but fair


Fairness is a difficult thing in a class of 450
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
28
Who to contact

I am not always the best person





I easily get inundated with emails, 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
Office hours will be posted on the website
There will be a lot of TA office hours

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



31
Sections

CS 101



CS 101-E




Students have little or no programming experience
Mandatory scheduled closed labs
Students with programming experience
Open labs that are to be completed by a scheduled time
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 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 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
