PHYS 214: The Nature of Physics

Fundamental goal of this course:

To understand the physical world around us.

Topics:

• falling bodies

• projectiles, satellites

• gravity

• energy, momentum

• heat, temperature

• electricity & magnetism

• waves

• light

• optics

• atoms

• nuclei

• relativity…

HELP:

• Ask Questions in Class If you have a question most

likely others have the same question

• Physics Help Center Room 237 Physics Building

• Discuss with other students in the class

The distribution of final grades?

If you do average work, you will

probably get a C

I would like to give all A’s and

B’s

Everyone can get an A if all the

material is learned!

Grading Procedures

Your final grades will be determined by five different

components:

C CHIP Homework

Homework problems are assigned for every lecture day of

the semester The problems are taken from the “Exercises”

section at the end of each chapter, as well as a few from the

“Challenge Problems” sections The assignments are listed

on the PHYS 214 web pages under “Problem Sets”

These homework assignments must be done using the CHIP

web-based system You must connect to the CHIP homepage for PHYS 214, using a standard browser Instructions can be found via the link to CHIP on the PHYS 214 web page

C CHIP Homework, cont.

Each problem will initially be awarded 10 points You can make five attempts to get the correct answer That is, you will

be notified if the answer you submit is incorrect, and you can resubmit your answer for a total of five attempts without

penalty To get full credit, the solution must be submitted by 7:30 am on the due date Half credit will be awarded to late solutions submitted within a week of the deadline; no credit will be awarded past that date

At the end of the semester, the final homework grade will be normalized so that a perfect score would be 100 points That

is, your homework score is equivalent in weight to one

evening exam

D CHIP Reading Quizzes (“Pre-Lecture Quizzes”)

You must also log in to CHIP and take a “Pre-Lecture Quiz”

before each lecture This will be a single, multiple choice question based on the posted reading assignment for that day You can take this quiz only during the two days preceding the lecture You have only one attempt, and will have only five minutes to submit an

answer You should read the assigned material carefully before

taking the reading quiz

Reading quiz scores will be normalized at the end of the semester

to make a maximum score equal to 50 points This is equal to half

of one exam, and is more than enough to raise or lower a student’s final grade Having read the assigned material is essential for the discussions and lecture quiz for each lecture

E Lecture Quizzes

Lecture quizzes be taken with the Audience Response System in Room 112 These questions are designed to test your

understanding of the material, to stimulate discussion with your fellow students, and give you an opportunity to improve your

understanding of the underlying physical principles After you have answered a question, you may be asked to defend your

answer to your neighbors, or to decide that perhaps they had a better answer You would then be quizzed again on the same

question These will also be worth 50 points towards your final grade Answers will be weighted so that some credit is earned for incorrect answers also, rewarding all who attend and participate and penalizing those who do not

How to use CHIP (see Handout)

• go to CHIP web site for PHYS 214

• After clicking on Homework enter:

• USER NAME first 4 letters of last name, last 4

numbers of SSN: char5432

• PASSWORD 214mn, where “mn” are the 4th and 5th digits of SSN

Follow instructions in handout for changing your password (highly recommended)

“Activ e Learning” & the Audience Response System

(ARS)

Research: Lecturing/passive listening does not work well

Active engagement is needed: Observe phenomena, discuss and

defend your answers to quiz questions

This can only work if you are prepared, by reading the

assigned material in advance You MUST do the reading

assignments!

“Penalty” for this system: less material can be covered in

class You will have homework problems and exam questions

on material from the reading, that may not have been

discussed in class
