Required materials

 

Textbook:  Brown, LeMay, Bursten, and Burdge, Chemistry, the Central Science, 10th edition (2006).  This is the same text that was used in CHEM 105.  The book should have come with an access code to the online homework program, Mastering Chemistry.

 

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 ChemistryIt 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. Arthur A. Low, Room 417, Phone: (254)968-9144, email:  low@tarleton.edu.  Office hours:  Mondays and Wednesdays:  9-10:30 AM, Thursdays:  2-5 PM.  If the only time you come to my office for help is immediately before or after the class time, you probably won’t receive much help.

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 6; Friday, February 29; Monday, March 31; and Friday, April 29.  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 WebCT.  You can login to WebCT 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 WebCT.  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 3 at 11:30 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).

 

ADA Information

 

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.
