Welcome to PHY2049 Physics for Engineers and Scientists II Dr. Bindell FALL 2008 Dr. J. B. Bindell

All of today’s material will be found on the website

Instructor: Dr. Jeffrey Bindell Schedule M,W,F 10:30 – 11:30 Room MAP 359 Phone (I almost never answer the phone … use ) Website: (All lectures and other documents including the syllabus) OFFICE HOURS: 11:30-12:30 AM MAP-417 or by appointment General Information

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.  “Cheat sheets” will be allowed – small index cards – No formula sheets will be distributed. 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. X  X >

i-Clickers 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. i-clicker

The Clicker - Registration Buy the clicker. Book Package is the cheapest approach.  Book  i-Clicker $10.00 discount (?) – Sell later for more $  “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. It usually does! Gives you something else to hate about the course.

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 & quizzes. Classes may begin with a clicker question or two about the reading assignment or the previous session. Reading assignments will be announced on WebAssign but will always be the beginning of the material that is next to be covered.

WebAssign Startup Digits of your PID ihatephysics 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 Physics

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 may 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. 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.  Think about it … we will decide later in the week Your lab will include a recitation hour.  This is an extra “recitation” class.. Last semester, most students said that these sessions were helpful for problem solving.

An Issue I create workshops for High & Middle School Science & Math Teachers on various topics in Science & Technology  (See techPATH tab) If I must miss a class I will either  Get a substitute,  Cancel the class if we are ahead of schedule, 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.

Now go forth and be studious See you on Wednesday for first serious lecture.
