: We will be using the Personal Response System devices (clickers) in class. Clickers can be purchased at the University bookstore by asking at the counter on the lower level.
Once you purchase a new clicker or replace a lost one you must register it
with the university. An unregistered clicker will be useless in class
. Go to http://www.clickers.umd.edu
(a picture of the
Response Card RF-LCD is on top on the page) and follow the Students link. This website will give you information on purchasing your clicker, registering your clicker, using your clicker and what to do if your clicker is lost/stolen. Our classroom channel to be used with clickers is 45 (accessible only when we use clickers in class).
Alternatively, you can use a Web Accessible Mobile Device
(iPhone/iPod/iPad, Blackberry,
laptop, etc)
. In such a case you will need to buy a license
from
ResponseWare
and learn how to use your device instead of a clicker (see instructions at http://clickers.umd.edu/students/index_students.html
). Our classroom ResponseWare session ID is
AV2012
(the session is open only when we use clickers in class).
There will be 20 clicker questions over the course of the semester, beginning
Sep. 10
, which you will be required to answer. These questions will be on the material recently covered in the course, which is a way to make sure you are keeping up with the material. Clicker questions may be given at any time during a class. Each clicker question is worth 2 points toward your final grade. Your 10 lowest clicker scores will be dropped when figuring out your final grade in the course. You will be able to keep track of your clicker points on the
Blackboard
. Clicker questions make up will NOT be possible.
:
We will be using the
Mastering Chemistry
on-line home work system. You need a
Mastering Chemistry Registration Code to gain an access to the website and complete assignments.
The Mastering Chemistry registration code is included along with your text in a package sold in the
University bookstore. If you purchased your text w/o the Registration Code you will need to purchase
Mastering Chemistry Registration Code separately at the University Bookstore or by going to http://www.masteringchemistry.com/site/register/new-students.html
.
All students will need to set up their
Mastering Chemistry
account before you can get started.
Our 2 pm class Course ID with Mastering Chemistry is AV2012 . Instructions for registering with
Mastering Chemistry and logging into the system and troubleshooting can be found on the Blackboard .
There will be thirteen homework assignments this term that you must submit. One more assignment
“Introduction to Mastering Chemistry”
does not give you points but is highly recommended to be completed before you begin working on your first actual homework. Your three lowest homework grades will be dropped when figuring out your final grade in the course. The number of questions in each assignment may vary. The total of 10 points can be earned for each assignment. You will have three attempts for each question. For not using hints when answering a particular question you are rewarded with a bonus up to 30%. Typically, you will be given one week to complete each assignment.
The places to keep track of when assignments are due are the syllabus and the assignment page on our section Mastering Chemistry web-site. Most of the assignments will be released at 3:00 PM on
Mondays and, except HW13, are due at 2:00 PM the next Monday. Note that no HW is due on Sep. 3,
Nov. 5 and Dec. 10.
The 50 min exams will be on October 3, November 2 and December 7. The final 2 hour exam is December 17 (1:30 am -3:30 pm).
All the exams are cumulative with emphasis placed on the new material.

Non-programmable
calculators will be allowed during the exams. A scientific calculator is recommended.
 No electronic devices other than your calculator will be permitted during any exam.
 Each student is required to keep his/her UM photo ID on the desk during the exam.

 If you know you will have a conflict with the dates of the exam, such as religious observances, you must be in touch with your instructor by the end of schedule adjustment (September 12).
 If you are ill on the day of the exam, you must contact your professor before the exam to make alternative arrangements. An e-mail or phone message
PRIOR
to the exam time would suffice.
Make up exams will be given only with a valid documented University excuse.
. It is the policy of the University to excuse the absences of students if the absence results from the following causes: illness of the student, or illness of a dependent as defined by Board of Regents policy on family and medical leave; religious observance where the nature of the observance prevents the student from being present during the class period; participation in university activities at the request of University authorities; and compelling circumstance beyond the student's control. Students requesting an exam make-up due to an excused absence must apply in writing and furnish documentary support for their assertion that the absence resulted from one of these causes.

The University of Maryland, College Park has a nationally recognized Code of
Academic Integrity, administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate and graduate students. As a student you are responsible for upholding these standards for this course. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic
Integrity or the Student Honor Council, please visit: http://thestamp.umd.edu/gh/academics/academic_integrity
Students are responsible for knowing, understanding and behaving according to the content of the Code.
There will be zero tolerance for any violations.
Only university-excused absences are allowed. Proper documentation is expected.
Your instructor must be contacted within 24 hours of the missed exam. Failure to meet these three requirements results in a ZERO for the missed exam
.
:
If you have a disability, please make an appointment to discuss available accommodations to maximize your learning experience in this course.
Learning disabilities must be documented by Disability Support Services prior to receiving accommodations
.

All re-grades must be turned in to the TA the same day the exams are handed back and at no other time. Re-grades will be returned to the students within one week. Note, however, that the entire exam will be re-graded and this may result in a lower grade. Steps to take for re-grade:
1.
Assess why you feel you were unfairly graded
2.
On a separate piece of paper write an explanation for why you feel a certain problem should be regraded. Write clearly and be succinct. DO NOT WRITE ON YOUR EXAM.
3.
Staple your explanation to the front of your exam.
4.
Turn in re-grades to the Discussion TA.
The last day for schedule adjustments is September 12 th
November 7 th .
. The last day to withdraw is
It is in your best interest to obtain lecture notes and supplementary materials for missed classes. You are responsible for: i) material included in our Lecture schedule
(see the list of Chapters covered either in full or in part on the last two pages of our Syllabus), ii) any additional material covered in class and iii) announcements made in class whether or not you are in attendance.
Questions are welcome during lecture. I strongly recommend that you write down your questions that you had no time to ask in class and ask them when you have a discussion session or visit me during my office hours. Please be respectful of others and turn your cell phones off.
The old saying is ‘practice makes perfect.’ Do not ever stop at the point when you just
“understand” the material. You are expected to develop skills at solving course-related problems. Practice at solving problems as much as you can. Remember, you will have only few minutes (3-5 min) per problem/question during any of your exams. This time should be sufficient for you to solve a problem and double check your answer!
Discussion sections will begin meeting on
Tuesday, September 4 . You are expected to work through the end-of-chapter and homework problems before your discussion meeting, so you can effectively discuss these problems with your classmates and the TA. After you take an hour exam, graded exam will be handed back and solutions will be given online on the Blackboard and/or during your discussion section.
You will have Guided Study Sessions held in the evenings twice a week by Robin Alonge ( ralonge@umd.edu
). In addition, there is a list of tutors for hire in room 2102 (chemistry advising office).
Your participation in the evaluation of courses through CourseEvalUM is a responsibility
you hold as a student member of our academic community. Your feedback is confidential and important to the improvement of teaching and learning at the University. CourseEvalUM will be open for you to complete your evaluations for Fall 2012 courses from Tuesday, November 27 through Wednesday, December 12.
