Three Methods to Calculate Class Grade

Criteria: Performance + Effort

1st Method to Calculate Class Grade

80%

20%

This means that you take classes all the time, submit your homework, and take all the exams. I can use your HW and tests scores to curve your final class grade.

There will be NO other grade curving in this class no matter how bad the exam scores look like!

2nd Method to Calculate Class Grade

100%

0%

This means that you do not need to submit your homework if you wish, but should take all the exams.

You must be sure you can do well in your exams!

3rd Method to Calculate Class Grade

100%

0%

If you do not want to come to class at all and do not want to take exams during the semester.

A number score will be assigned to you using the highest score from the 3 calculation methods

However, fail to take the final exam will result in an “F”.

Grade Calculation

I will drop the lowest score in each grade catalog.

Exam Grade

Exam grade =

Policy: Exam

2020

Do bring your UGA ID with you when take an exam!

AllowedA writing instrument A pocket calculator A rulerOne 8.5"×11" paper containing constants, formulas, and any other information that you might find useful (NOT any kinds of solutions). Both sides of the sheet may be used.

Not allowedLaptop Tablet (include ipad) Cell phone Use of these or other electronic devices during an exam is a form of academic dishonesty

Policy: Absence from a Class

2121

• Inform me (call or e-mail) before class begins

• Submit a formal note to me with reasonable excuses (such as a note from a doctor if you are sick, etc.)

A grade of zero will be awarded for any homework or exam that is missed without a valid reason.

Policy: Class Withdraw

2222

• Attend the class and hand in home-work regularly, withdrawing before the withdraw deadline, he or she will obtain a “W”.

• DO NOT attend class and DO NOT hand in homework, withdrawing within a week right before the withdraw deadline (<40% of classes and numbers if homework up to the date of withdraw requirement), he or she will obtain a “WF”

Policy: Academic Integrity

2323

The first occurrence of academic dishonesty will result in a score of zero on the assignment, activity, test or exam in question, and the violator will receive a written warning.

A zero received as a result of academic dishonesty will NOT be dropped fromthe record as the lowest grade.

The second occurrence of academic dishonesty will result in an F for the course.

Information: Final Exam Problems

2424

1. In-class activities

2. Homework problems (may change slightly)

3. Class examples (including examples in textbook)

4. Old exams, including Tests #1, #2, #3, and old exam problems posted in eLearning Commons

Information: Efficiency of Learning

Information: Office Hours

My office hours are usually immediately after the Wed./Fri. class. If you do have questions, please stop by.

Information: Where to find HW

1. Your HW will be distributed before class starting on Thursday

2. If you missed the class, you can find you HW in small bins outside myphysics office (Room 209)

Information: Contact Me!

If you have questions and need to make an appointment with me, DO send e-mail to my e-mail address: zhaoy@physast.uga.edu, or call me at 542-7792

If you do not receive my e-mail reply, please do check whether you put a wrong e-mail address

For those appointments, I usually will be in Riverbend office (see map above)

Information: Lab

Lab coordinator: Mr. Tom Barnello (tjbar@hal.physast.uga.edu)

• The lab syllabus is at my course website or at http://www.physast.uga.edu/courses.

• labs start in the week of Aug. 24 and students should read through the appropriate exercise in the lab manual BEFOREcoming to lab

Please print out a copy by yourself !!!If you are retaking the course and are happy with the final lab grade you received

previously, you do not have to attend the lab. You do have to remain registered for the lab, but you do not have to attend. Please contact the Lab Coordinator (Tom Barnello--Room 310 tjbar@physast.uga.edu) if you want to exercise this option. If you would like to improve your grade, you must do ALL of the lab exercises again.

Research for Undergraduates

I always welcome undergraduate students to work in my lab. Please contact me if you are interested.

For the past 10 years, there are over 40 undergraduate students worked in my lab. They have published papers or gave presentation in different conferences.

Research Experience for Undergraduates

Apply learned knowledge to solve real world problems:

better understand your class work

Get to know professors personally, so that better

recommendation letters can be written for future career

Become a co-author of paper(s) published in peer-reviewed journals, which

will position you in a better level when compete with

other peers

Get paid through research

Examples
