Required materials
Textbook: Brown,
Mastering Chemistry:
An
online homework program that counts as a significant portion of your lecture
grade. Course ID #:
MCLOW42502
Lab book: For the regular labs (Sections
530 and above), a lab book is available in the book store for purchase. Be sure to buy the lab book for the second
semester. This book has just been updates so an older lab book from a previous
semester will not work this semester!!!!
The lab book for the honors lab (sections 510 and 520) will be given to
you during the 1st week of the semester.
Calculator: A non-programmable scientific
calculator (with trigonometric functions) will be required for exams.
Course procedure
You will be expected to attend all classes and
labs. CHEM 108 proceeds at a faster pace
than CHEM 105, especially at the beginning of the semester. If you miss 1 or 2 classes during the first
couple of weeks, you will find yourself seriously behind in the course and will
have little time to catch up. You need
to start studying the material starting with the 1st week of the
semester by learning the definitions given in lecture and applying them in
doing the assigned homework.
There will be assigned homework given online using a
program called Mastering Chemistry. It is
essential that you do these homework problems in order to learn the material and
perform well on the class exams!!!
Your grades on the homework exams comprise one-third of your lecture
grade and will seriously lower your grade if you do not do the homework
assignments. You will be given more
information about this homework program during the 1st lecture of
the semester. Generally, you will be
given an assignment for each chapter.
For most assignments, you will have at least one week to complete the
problems. There will be a due date and
time for each assignment. Late
assignments will not be accepted for a grade.
There are no exceptions to this
rule!! Do not wait until the due
date to start working on the homework assignment. If you encounter a problem with the online
homework program, you need to come to my office and reproduce the problem on my
computer. If you call me over the phone
or email me about problems that you are having, all I can do is check if you
are registered on the program correctly and whether the assignment is active.
In addition, this syllabus lists certain
end-of-chapter problems from your textbook that I think you should know how to
answer. They are called “suggested
homework problems” in the tentative schedule given at the back of this
syllabus. These “suggested homework
problems” will not be collected nor graded.
They are for your practice in problem solving. The answers to these suggested homework
problems will be posted on my Tarleton website at www.tarleton.edu/~alow in the posted
syllabus for this class.
There is a large amount of material covered in this
class. The material covered in this
class is set by national standards and is something I cannot change. If you wait for a few days before a class
exam to begin studying, you will be quickly overwhelmed by the amount of
material. Ideally, you should study the
material in this course on a daily basis between 30-45 minutes per day, 5 days
per week. I am sorry if you feel the
pace of the course is too fast, that is something that cannot be changed. If you encounter difficulty in the course,
you need to seek help immediately.
Sources of assistance include:
1. The
textbook: reading your textbook may
give a different way of viewing the material presented in class. This may help you in understanding the
material. Each chapter also contains
typical problems with the answers worked out with explanations.
2. Your
professor: Dr.
3. My
website at www.tarleton.edu/~alow: This website contains links for all the
courses I teach. If you look for CHEM
108, there are a number of different semesters.
Look for the Spring 2008 CHEM 108 link. The website contains the syllabus,
the class lecture notes files, keys to exams that were given previously, and
handouts given out in class.
4. Supplemental
Instruction (SI): There should be an
SI instructor assigned to our lecture. A
schedule of help sessions should be arranged by the second week of the semester.
5. Perhaps you might want to form a study group
with other students in your class.
Remember a study group works best when all the students participate.
Grade Evaluation
Your grade in this course is evaluated on the basis
of your performance on three parts of this course: the lecture, the lab, and the final
exam. You will receive a grade for each
part. Your course grade is a weighted
average of these three grades with the lecture grade counting 50%, the lab
grade counting 25% and the final exam grade counting 25%. For example, if your lecture grade is 75,
your lab grade is 85 and the final exam grade is 77, then your course grade
would be 80.3:
Course grade = 
Letter
grades are assigned based on your course grade:
90-100: A; 80’s: B; 70’s: C; 60’s: D; below 60: F. You
may not pass this course without passing both the lecture and lab portions of
the course separately. This
means that if your lab grade is below 60 or your lecture grade is below a 60,
you will automatically receive a grade of “F” regardless of whether your course
grade is above a 60. The lecture grade
may include the final exam grade if necessary.
This means that if you receive a lecture grade below a 60, it is still
possible to pass the course if you pass the final exam. If you receive a lecture grade above a 60,
then you have fulfilled the lecture passing requirement.
Your lecture grade is based on your performance on
the 4 class exams and the homework.
There will be homework assignments given during the course of the
semester. From the grades on the
homework assignments, a homework average grade will be calculated by averaging
your 10 highest grades on the homework assignments over the course of the
semester. Your lecture grade will be calculated
by calculating the average of your 4 class exams and your homework average
times two. For example, if your grades
on the 4 exams are 75, 82, 54, and 84 and your homework average is 88, your
lecture grade would be:
Lecture grade = 
Over
the course of the semester, you will probably have about 15 homework
grades. Therefore, your 5 lowest
homework grades will be dropped. No exam grades will be dropped!!
You will have 4 exams during the course of the
semester. The dates that the exams will
be given are: Wednesday, February 4;
Friday, February 27; Monday, March 30; and Monday, April 27. Each exam will consist of 10 multiple choice
questions worth 4 points each for a total of 40 points and 5 numerical problems
consisting of 3 ten point problems and 2 fifteen point problems. On most exams, there will be 10 points of
extra credit given for correctly defining important terms. Each test will cover the material covered in
lecture from the 1st day after the last exam given in class up to
and including the material covered on the lecture before the exam to be
given. The score that is written on the
exam is the raw score you obtained on the exam.
Each exam will be curved to a certain extent. The curve will be given to you in terms of
grade ranges for the letter grades. The
grade ranges apply to the score that is written on your exam. The most typical curve grade range that I use
is: 87 and above is an “A”; below 87 and
above 74 is a “B”; below 74 and above 60 is a “C”; below 60 and above 46 is a “D”;
and below 46 is an “F”. Your curved
grade will depend on where your grade lies in the range given above. For example, if your score on the exam is a
“70” that would be given a curved grade of “76.9.”
The grades that you obtain in this course will be
posted on Blackboard. You can login to
Blackboard using your school ID number and pin number. These are the same numbers that you use when
you register for classes and/or check your grades. Please remember that the only score that I
write on the exams given in class are your raw scores before the curve has been
applied. The grade ranges for the curve
apply to these scores. Your curved grade
will be posted on Blackboard. The grade
ranges given for the curve do not apply to these grades.
The final exam for this course will be given during
the Freshman Chemistry slot on Saturday, May 2 at 8:00 AM. The final exam consists of two parts. The first part is a national exam written by
the American Chemical Society. It covers
the entire year of College Chemistry (both CHEM 105 and CHEM 108). It consists of 50 multiple choice
questions. You will be allowed 55
minutes to complete this part of the exam.
The second part is an exam written by me and will have a similar format
as the exams given in class (10 multiple choice questions and 5 problems). Your final exam grade will be a weighted
average of your scores on the two parts with the first part counting 40% and
the second part counting 60%.
Makeups for exams given in class
Makeups will be given for exams
only. Makeups
will be given during the week after the exam was scheduled. The makeup exam will cover the same material
as the class exam but will consist of different questions. It is up to the student to arrange a time to
take the makeup exam with me. Arranging
a makeup exam is most easily done with me in person.
Cellphones and Laptop Computers
All cellphones and pagers either need to be turned off or set
to silent vibrate during lecture!!! The ringing
of cellphones and pagers is very disruptive not only
to me but also to other students in the class (even if they deny it). If you need to be contacted by someone during
the lecture, please set your phone to vibrate and when the person calls,
quietly leave the class, answer the phone, and then return to class when you
are done. Cell phone ringing repeatedly
in class will severely agitate your professor.
Agitated professors will tend to give pop quizzes in class and write up
harder exams. Please remember that you have been warned!!
You may use laptop computers during lecture. However, if I notice that you are checking
your e-mails or looking at videos during class, I may ban the use of laptop
computers during class. You should be
using the laptop to assist you in taking notes during the lecture. It should not be a source of distraction.
Calculator policy
It is the departmental policy that programmable and
graphing calculators will not be allowed for use on quizzes or exams given in
class. You will be allowed only a non-programmable
scientific calculator. Violations of
this rule will be treated as an act of academic dishonesty (you will be given a
“0” grade and reported to the dean of students).
If you need accommodations due to a disability, you
need to discuss your needs with Ms. Trina Geye, Director of Student
Disabilities at 968-9400. Her office is
in Room 201 in the Math building. You
need to provide them with documentation of your disability. Then, Ms. Geye will send me a letter of
notification about your disability. You
will also receive a copy of this letter.
Please read this letter carefully, it will outline the procedure that
you need to follow in order to receive your accommodation. If the
procedure outlined in this letter is not followed, it is possible that you will
not obtain the accommodation requested.
