Books and Stuff
 Serway and Jewitt “Physics for Engineers and
Scientists”, Volume 2, 7th Edition Thompson –
Brooks/Cole
 You need to get a WebAssign LogIn (Bundled
with NEW textbook)
 You need to purchase an “i-clicker” and register
it on the web.
 You must answer a clicker question in class to
complete the registration.
 Anyone seen with two clickers in class will be
shot!
Keep This in Mind
The Dirty Little 2049 Secret:
 The percent of initial registrants who receive a
grade of D,F or W for most instructors:
Based upon interviews with some of the
47% of the 2049 population:
 Students waited too long to get down to serious
studying and by then it was too late.
 Students blew off lectures because they were
boring.
 Students stopped working on the course from
time to time because of the pressures of other
courses.
 All agree that this one of their most difficult
courses (when taken at the appropriate time)
 Many state that their calculus skills were not up
to the challenge of the course.

Examinations
There will be THREE examinations
Schedule to be announced.
There will be a COMPREHENSIVE final
examination during final exam week.
There will be a short quiz each Friday at
the start of class.
Be on time on quiz and exam days. You will not
be given extra time if you are late for any
reason.
Student IDs
For i-clicker registration and for
WebAssign your ID will be your PID
 without the leading letter but
 including any leading zeros.
#(*&#@$ i-Clickers
i-clicker
 Will be used throughout the course.
 Will be used daily.
 Usually for class questions: Correct Answer=3,
Incorrect answer=2, No answer=0. (Will Vary)
 For clicker quiz (if there are any), only correct answers
will count.
 Because you get credit even for wrong answers, clicker
scores should be pretty reasonable.
The Clicker - Registration
 Buy the clicker. Book Package is the cheapest
approach.
Book
i-Clicker $10.00 discount (?)
“Extended” WebAssign Registration Card
 If you buy a used book, you need to purchase
the other items separately.
 There is a code number on the back of the
device you will enter when you register your
clicker. Instructions are on the website.
The Clicker What??
CODE
Why Clickers
 Gets you to class.
 Keeps you awake and focused on what is going
on.
 Gives me an idea of which concepts are getting
through and which are not.
 Should help your grade.
If you answer all questions wrong, your average will be
a 66%.
Since you should get some questions correct, this
should help your grade.
 Gives you something else to hate about the
course.
SURVEY QUESTION: Do you have a
clicker with you? Use it to answer the
following.
A.Yes
B.No
Homework
It is important to notice that homework counts for a
significant % of your grade. Homeworks will be based on
WebAssign. Although “extensions” will be available, valid
reasons should be offered at the time or he request.
There will usually be 8-10 problems assigned each week.
These problems often pop up on exams.
Classes may begin with a clicker question or two about the
reading assignment.
Reading assignments will be announced on WebAssign but
will always be the beginning of the material that is next to
be covered.

Be sure to change your
password as soon as
possible to avoid someone
else doing your homework!
My gripes ….
Students study at the last minute.
Students have big holes in their math
skills:
Interpreting Graphs.
Using Calculus.
Students come to my office expecting me
to solve their homework problems.
I will always help … I will not always give you
the answers!
Work on the problems before you come for
help.
Things to do with the textbook that you
just spent a lot of money on:
Sleep on it! Osmosis.
Improve your balance
Feedback Based Approach
 More demos when possible.
 More problems in class
 Minimize PowerPoint.
 Last semester’s PP notes are on my website. Watch out for
some errors that were not corrected on the slides.
 PP are a matter of opinion and no matter what I use for
delivery, 50% of the class is unhappy.
 This semester I will reduce the amount of lecturing that I do
with PP but in order to do this YOU have to read the material
to be covered in the class.
 This will provide more time for problem solving.
 REMEMBER: I am NOT the textbook and I don’t replace it.
How to get an A.
 Weekend
 Read next weeks material.
 Try to complete assignment before class time.
 During Week
 Work the long problems from WebAssign
 Different problems will usually be worked in class.
 Ask Questions
 Come to office hours for help.

Fridays will usually be Quiz day. Some will be “strange”.
Most exams will be on Fridays except for Good Friday.
Studying helps!!
$100,000 small bills
An offer:
 This room should be vacant from 7:30 – 8:30
AM.
 If you want, I can use this hour (probably on
Fridays) to answer questions, work problems,
etc.
 Your lab will include a recitation hour.
 This is an extra “recitation” class.
 Think about it … we will decide later in the week.
 Last semester, most students said that these
sessions were very helpful for problem solving.
An Issue
I create workshops for High & Middle
School Science & Math Teachers on
various topics in Science & Technology
www.floridahightech.com (See techPATH tab)
If I must miss a class I will either
Get a substitute, or
Use a 7:30 slot to replace the class I miss
What’s Up?????
Clicker use starts immediately
We begin with chapter 23.
Charge, Coulomb’s Law and Electric Field
We are “scheduled” to cover
approximately one chapter a week.
This is a VERY fast pace!
I usually can’t accomplish this.
All chapters depend on previous chapters
Don’t fall behind
Reminder
This is a hard class.
If you don’t get it, “it” will get
you!
Start reading the first chapter.
Check WebAssign
