http://highered.mcgraw-hill.com/classware/selfstudy.do?isbn=0072980605 .
COURSE OBJECTIVE: This is the second semester of a yearlong course. We will be covering most of
the latter chapters of the text. You are taking this course because the field of chemistry fascinates you
and/or you need to take chemistry as part of a degree requirement for you major. It is designed to
familiarize you student with general qualitative and quantitative aspects of chemical sciences. It should
also provide you with tools for solving scientific problems in the context of chemistry. As the course
progresses, attempts will be made to draw parallels with the theory of chemistry to everyday situations in
life.
The course will require consistent study on your part. You are encouraged to preview the relevant
material prior to lecture (as outlined later in this syllabus) and the corresponding problems at the end of
each chapter. You are expected to complete the homework problems before each recitation
section. Please keep in mind that if you are having problems with the material, there are many sources of
outside class assistance that are available to you. Remember, that unlike in High School, the instructor
will not be continually goading you to study the material. A good rule of thumb for any course is that
for each hour of class time, you should spend 3 hours outside of class studying (or about 10 hours
each week).
CLASS ATTENDANCE / PARTICIPATION: Lecture and recitation attendance is mandatory as outlined in
the Villanova University Blue Book. Attendance will be noted each class period. In the case of an
absence, the instructor expects a written explanation in the next scheduled lecture. If you are sick, go to
the Health Center. The staff will be happy to help you and will provide you with written
documentation. Abuse of the privilege of “excusable absences” will not be tolerated and will be referred
to the appropriate departmental faculty and/or the Dean of Arts and Sciences. Class participation is
strongly encouraged. Not only does class participation make the classroom experience more interesting,
but also your grade depends on it. Each student will be issued a class participation score from 0 to 50
points.
EXAMS: There will be a total of eleven quizzes, one mid-term exam and a final exam. The exam dates
are listed at the end of this syllabus. The mid-term and final exams will be comprehensive. Each quiz
will be graded out of 30 points and the top ten quiz scores will be used to determine the course grade (300
total points). The mid-term exam will be graded out of 100 points. The final exam will be graded out of
200 points. The specific material covered in the exam will be indicated in the class prior to the exam. The
format of exams will be a mix of multiple choice (MC) and show-your-work (SYW) problems. Normally, the
exams will be graded and returned the class following the exam and any questions concerning an exam
can be discussed during an appointment. Any person not attending the class following an exam will be
responsible for making an appointment to pick up and discuss the exam result. The exam dates will not
change. Make all appropriate arrangements to be in class on time on those days. There are NO makeup exams or quizzes and there should be no requests for extra credit assignments. If something
unavoidable happens that requires you to miss a testing date, consult with the instructor BEFORE the
exam or quiz to discuss your situation. All other absences on testing days must be accompanied by
documentation of disastrous events. (These are described on the next page of this syllabus.) Alternate
arrangements can be made, if your unavoidable absence is verified.
COURSE GRADING: Each quiz will be graded out of 30 points. The mid-term exam will be graded out
of 100 points. The final exam will be graded out of 200 points. The class participation score will be from 0
to 50 points. The course grade will be calculated as:
Course
Grade (%)
= (quiz point total) + (mid-term exam) + (final exam) +(class participation score) x 100 %.
650 points
The following scores will ensure the corresponding grades:
100%-90%: A, 89%-86%: A-, 85%-83%: B +, 82%-80%: B
79%-76%: B-, 75%-73%: C+, 72%-65%: C, 64%-55%: D, < 55%: F.
The instructor reserves the right to modify the exact grading levels and to adjust point totals to reflect the
grading of homework assignment.
CALCULATORS: Calculators with Scientific Notation are required for in class exercises; therefore it is
important that you bring your calculator to each class so that you can effectively participate in the learning
process. You will require your own calculator for examinations, unless told otherwise. Sharing of
calculators is not allowed. Direct passing of calculators between students will result in a score of ‘0’ for
each student for the exam or quiz involved. You should ensure that your calculator is fully charged or
has new batteries before each exam.
LAPTOP COMPUTERS AND OTHER COMPUTERS: Laptop and other computers are not required,
although many students find them quite helpful. Students may use laptops and other computer devices to
access course information during class (especially for MS PowerPoint presentations). If a student is found
to be using these devices for other purposes (such as, e-mail or instant messaging) during class time, their
privilege to use these devices will be terminated. These devices may not be used during exams or quizzes.
CELL PHONES: Cell phones can be very disruptive in class. Cell phones must be turned off during
class time. If a student’s cell phone rings during a quiz or exam five (5) points will be deducted from their
quiz or exam score.
HOMEWORK: Practice, practice, practice !!! Homework assignments from the textbook are given later
in this document. Additional homework problems may be given in separate handouts. They are to be
considered the minimum number of problems you should be working in mastering the course
material. Homework problems are typical of what you can expect on the examinations. Further, it should
be realized that in class there is only a finite amount of time and hence limits the total number of examples
that can be covered. If you have trouble with the homework assignments you should bring these
questions to the recitation section or make an appointment to see me or contact me via e-mail. NO
Chem 1156 lecture time will be devoted to working out specific listed or unlisted text problems. There is
not enough time to go over every homework problem in the recitation sessions, so come to the session
prepared with your questions. Satisfactory performance in this course requires that you regularly
complete and understand the homework problems. It is important that YOU attempt to work the
2
homework problems on your own. Solutions can look much easier when someone else is working the
problems.
DROPPING THE COURSE: Failure to attend class will not constitute a drop of the course. Action on your
part by filing a drop slip with the registrar is required; otherwise you will receive an “F” grade on your
transcript.
DOCUMENTATION OF DISASTROUS EVENTS: Disastrous events include serious and disabling
accidents, doctor-mandated absences due to serious illness, and deaths or serious and disabling
accidents in your family. In each of these cases, you are required to document the circumstances of the
incident sufficiently so that the incident can be independently verified. Examples of relevant documents
include copies of police reports, hospital admission papers, or a doctor’s note with an explanation of the
circumstances. All of these must include name(s) and valid phone number(s) for independent verification.
If you miss an exam due to avoidable circumstances (e.g., oversleeping, getting stopped for speeding,
needing to go to work, needing to drop someone off or pick someone up, forgetting that there’s a test that
day, vacation with family or friends, etc.), expect no allowances to be made. If you are late for an exam
due to avoidable circumstances, plan on no extra time being provided.
OFFICE HOURS: Office hours belong to the students. If your instructor is talking with another faculty
member or doing something else, feel free to interrupt during office hours. If your instructor is talking with
another student, please wait your turn. Four office hours are available each week for any student who has
any questions or problems. Please take full advantage of office hour time by preparing specific questions
prior to arrival.
ACADEMIC HONESTY: It is perfectly acceptable, even advisable, for you to work and study with other
people as you work to learn the material in this course. It is easier to accomplish what needs to be done;
sometimes it’s even more fun. However, even if you study with others, you must demonstrate what you,
yourself, have learned.
Honest behavior includes, but is not limited to, the following:
•
Providing accurate representations of what you figured out, what you know, and what you
understand.
•
Providing individualized solutions and distinctive written work on everything you turn in for credit.
•
Using only those materials explicitly allowed (e.g., mathematical calculators).
•
Seeking and following specific verbal and written directions and instructions.
•
Stopping when the time limit is announced during a timed test.
•
Resisting the temptation to ask someone else to do your work for you.
•
Declining requests to do another person’s work for them.
•
Resisting the temptation to copy someone else’s work -- especially if you are avoiding doing your
own work.
•
Preventing anyone else from copying your work -- especially if that person is avoiding doing
her/his own work.
•
Resisting the temptation to use unethical and/or illegal methods to gain an unfair advantage or
to otherwise avoid doing your work.
All suspicious behavior will be monitored. All suspicious activity or dishonest behavior will be
investigated, and corrective measures will be taken. Penalties will apply to anyone violating this code of
behavior.
STUDENTS WITH DISABILITIES: Villanova University strives to provide an environment for personal
and intellectual growth of all its students, and also complies with the Americans with Disabilities Act of
1990 and Section 504 of the Rehabilitation Act of 1973. In order to meet these commitments, Villanova
