Keep This in Mind

The Facts … F includes people who forgot to withdraw and just stopped attending.

Last Semester This was worse than usual.

The Dirty Little 2049 Secret: The percent of initial registrants who receive a grade of D,F or W for almost all instructors:

Based upon interviews with some of the 47% of the 2049 initial 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 was their most difficult course (when taken at the appropriate time) Many state that their calculus skills were not up to the challenge of the course.

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.

The Clicker - Registration Buy the clicker. Book Package is the cheapest approach.  Book  Clicker  “Extended” WebAssign There is a code number on the back of the device that I need. Send me via piece of paper of  Your name  PID  Clicker Code Number

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.

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.

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 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 semesters 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 Fridays will usually be Quiz day. Some will be “strange”. All exams will be on Fridays except for Good Friday. Studying helps!!

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. 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.

What’s Up????? Today  Introductory Comments  Electricity (??) Wednesday  Charge and Electrical Forces  Problems Friday  Complete the Chapter  Problems  Will try to start clicker use

Reminder This is a hard class. If you don’t get it, “it” will get you! Start reading the first chapter.
