Spring 2005

[Page retired. Last entry 9 May 2005]

CHEM110 - CHEMISTRY Section 3, 3.0 credit hours

INSTRUCTOR: Dr. Petr Vanýsek; Office, Faraday West 418

Meeting place: NIU Campus (building 27 on the map), Faraday Hall_143

14:00-15:15 Tu, Th - Section 3 (16 enrolled, as of 9 November 2004, 30 as of 15 Nov., 170 on December 1, 2004 -- class closed)

This Web version is somewhat different from the syllabus given in class. It will be also updated or corrected during the semester. For class policies, the printed syllabus, as issued in the class on the first day, prevails.
The departmental version at
http://www.chembio.niu.edu/chembio/courses.html is unfortunately not very up to date.

Deadline to withdraw form the course:
Friday before the spring break. By that date you will have taken three tests, which should give you good feel whether perhaps it would be advisable to drop the course.

Late drop  !

Catalog description of the course

 

TEXT: General, Organic and Biochemistry (sorry about the poor grammar of the title) Structures of Life. Special Edition for Northern Illinois University. ISBN: 0-536-83168-8 Publisher: Pearson Custom Publishing, Boston 2004.

NOTE: The soft cover brand new condensed version sells at the NIU bookstore for $86.65. There is also available a used textbook by Timberlake, which is the full version (two semester course), which retails for $92.25. You should consider whether a buy-back at the end of the semester is an option, and whether you prefer lighter brand-new book and decide what is better value for you. If you plan to sell the book back, then buying the used hardcover will be eventually cheaper for you.

(You may be taking concurrently CHEM 111, the laboratory to accompany 110. The instructor responsible for the laboratories is Dr. D. Ballantine, Jr., Faraday West 424. The lab and class grades are independent.)

Final  - Tuesday, May 10, 14:00-15:50

    NOTE THAT TAKING THE FINAL TEST IS REQUIRED.

Test results: You will receive a slip with your score, the list of correct answers and the list of your answers in the class, at the first opportunity after the test/quiz is given.

OFFICE HOURS: 15:30-17:30 Tuesday and Thursday. Other times by appointment. I will help you with your problems, but come to see me with questions and problems already at least partially prepared. Do not expect the instructor to give you your own private make-up class. When coming to the office hours, be prepared to share the office or the time with other students. There is also help available, every working day, through the departmental tutors, and also through a leader in the supplemental instruction.

Proctors: Dill, Zeleke, Vadali (added 18 January 2005)

Required calculator: 30xabig.jpg (30297 bytes)

There is a REQUIRED calculator for this course, Texas Instruments TI-30Xa. If you plan to use a calculator during tests or quizzes, than it is the only one allowed. If we perform calculations in class or during practice, all will be explained using this calculator. [Shop around. The NIU bookstore has it for about $14, Wal-Mart had it for $ 9.88,  Target sells the same for $ 9.86 and Office Depot had them for $ 9.99.]
Rationale: (1) Modern technology allows storing lot of data in small devices and some of the calculator-like device can communicate with the outside world. Access to unapproved material or communication with others during a test or a quiz is cheating. To prevent this and assure that all students have identical opportunity a single calculator without such capabilities is permitted. (2) If you need a help with your calculator (rather than the calculation), I can help you only if I am familiar with your calculator. Thus, to be able to help everybody, I will learn the detailed operation of this one.
Note: Make sure you get the TI-30Xa model and not some similarly sounding one. For example TI-30X IIS and TI-30X IIB (both with a two line display) are not acceptable. The IT-30Xa exists also in a solar powered version and in the eco (ecological friendly) version. Any of these three versions is acceptable. Write your name on the back of the calculator so that you can identify it. There will be 170 identical ones in the class.

Have a calculator and a pad for calculations ready for each class period. The lecture will be always interspersed with your active participation.

For tests it is assumed that everybody has the specified calculator, pencil No. 2 (for computer grading forms), a pen for essay answers (only answers written in permanent ink can be reconsidered if you suspect an error in grading of an essay question or expect reconsideration for partial credit), and adequate knowledge to answer correctly the questions.

The course relies on active knowledge of mathematical calculations and the ability to setup algebraic equations. Helpful for those insecure in mathematics are the following books: Miller, Lial, Schneider; Fundamentals of college algebra (MATH 110 book, or similar); Dorothy M. Goldish: Beginning mathematics for beginning chemistry, 4th Ed., Macmillan, New York, 1990. Walter J. Gleason: Is your math ready for chemistry?, W. C. Brown Publishers, Dubuque 1993.

EXAMS AND GRADING:

Four(4) 75-minute tests worth each 100 points. The test with the lowest score will be dropped. Therefore the total possible score from tests is 300 points.

Note that dropping one test takes care of one absence. There will be no other forms of make-ups for tests for any reason.  

Comprehensive final test 40% (200 points) [TOTAL 100% = 500 points]

The work is multiple choice. Only one of the five answers is correct. Scoring is the benevolent "right answers only" versus the more stringent, discouraging guessing "right minus wrong." However, if you check more than one answer, than that question does not count (i.e., you cannot check all five answers and assume this will be always right.)

Your class percentage will be calculated as the sum of all the points earned (with the worst in-class test dropped), divided by 5. The grades will be as follows (verbal meaning as per the NIU catalog):

A Outstanding competence 80% and more

B Above satisfactory competence 70% to 79.99%

C Satisfactory level of competence 60% to 69.99%

D Marginally satisfactory competence 40% to 59.99%

F Unsatisfactory level of competence < 40%

The tests will typically consist of the following groups of questions: 1/5 - straight (one equation) calculation, 1/5 - more involved mathematical concept, 2/5 - factual knowledge, based on the lecture and detailed in the textbook, 1/5 - factual knowledge based on information in the lecture.

Estimating your class grade: After you have taken at least one test, then the average of the tests used in connection with the above grading scheme is a good indication of your present grade. Please, do not ask me "what is my grade so far." You can estimate it better than I can, since first, I have to look up your test scores, while you already have them, and second, you know much better than I do why you performed on a test in a particular way and whether your future performance is likely to improve, remain the same or worsen.

 

Note on mathematical background:
    This course of introductory chemistry is replete with mathematical problems, known as "word problems." In those, one has to figure out first what needs to be calculated and then do the actual calculation, usually not hard with a calculator. However, setting up the problems may be challenging for some.     

    Take as an example the following problem: Seven lemons sell for three dollars. How much will it cost to buy twelve lemons? This is a simple ratio calculation and the answer should be $ 5.14. You should try, right now, to do the math. If you are not comfortable with doing this problem, whether with a calculator or on a piece of paper, and do not know immediately how to set up the numbers to get the answer, then, you will have a major problem in this class. Algebra and solving word problems is the gateway to high-paying jobs. Do not take CHEM110, enroll instead in a math skills refresher course. 

Using the scannable forms for tests or quizzes:

Scantron form.jpg (1625254 bytes)

Use the usual pencil (Pencil No. 2) to fill in ovals. You can use a refillable lead pencil. The equivalent of No. 2 hardness is HB.
Staedtler refillable pen.jpg (17789 bytes)Staedtler leads.jpg (9644 bytes)

Be sure that you fill in your last name (and fill in the corresponding ovals) and include your initials. If you have just one initial, leave the second field blank. If you change your name during the semester, it may be more practical to keep using the old name/initials.

The block for the ID NUMBER has 9 spaces and it was originally intended for the social security number. The university can no longer use the social security number for identification. Instead you will use the "Z" number, issued to you as a computer logon and a general (e.g., library) identification number. It starts with the letter Z and is followed by 6 numbers, e.g., Z032673. Omit in the SCANTRON the letter Z and write the six  numbers as your student ID starting at the leftmost column. It will leave three empty spaces at the end. Note that many of the numbers begin with "0" That is a valid number and you must include it. It is important to use the number as the computer grading system tracks you by the number first and by the name only second. In rare situations there is more than one person in the class with the same last name and identical initials. The number, though, is unique.

To obtain the "Z" number you can call 752-7738, or go on the web to http://www.niu.edu/directory.shtml, type in the box your Last_name First_name and your e-mail will show up, such as z041434@students.niu.edu. Your "Z" number is the z041434, the number you would use for your identification on the Scantron sheet is 041434.

In the "MISC" column the SEC stands for your section number. You may fill it in (1 or 2), but it is the same for the whole class, so it is not essential. The vertical "FORM" is for distinguishing which form (version) of the test/quiz you received. It would be noted on the top of the test, quiz as A, B, D, E, E, F. If there are different forms, it is very important you fill it in.

Answer the questions in the following four columns. Line 1 is for question 1, 2 for 2, etc., up to 100. The back page has space for additional questions, above 100. It will not be used in this course. However, when you are done with your work, please, sign the back of the form in the rectangle provided.

For tests there will be a seating chart, with a seat number assigned to each student. The layout of Faraday 143 is here.gto.gif (1935 bytes)

Sign the form: On the back of the form is a place for you to sign your name. Please, sign after finishing the the test, not before. By signing, you are affirming that you have neither received nor given an unauthorized assistance in completion of this work and that you are the person whose ID is shown on the front page.

ACADEMIC DISHONESTY:

DON'T  sep.jpg (5187 bytes)

In general, cheating means presenting or using work that was not done entirely by you and, in the case of in-class examination, it includes also presenting or using your work that was written outside the classroom. You may not talk or pass notes to each other on any subject. Having other materials than those allowed for the work with you within reach during test or sharing calculators is cheating as well. Keep what you may need for the test within reach and keep what you should not have with you in your closed packs or better yet, do not bring it in. During tests you must put away any devices that would allow you to communicate with others or access databases. You are allowed to use only the specified calculator. Any other type has to be put away. Any such use during graded in-class work will result in zero on your work. I cannot investigate the nature and legality of your outside contact.

Other issues:

No smoking in the building, no food or drink in the class.

TAPING/RECORDING OF THE LECTURE:  You are encouraged to take good notes, reflecting your interpretation and understanding of the lecture. However, you are not permitted to make verbatim recording or transcription of the lecture.

ATTENDANCE: Attendance at the lectures is not monitored but it is in your best interest to be there. Consider the following: (1) The tests are based on the textbook material covered in the class as well as the class material, which may not be in the textbook, (2) Office hour cannot be used to catch up on material missed by a class absence. (3) One fifth of the questions on test is based on information given in the class but not in the book. LATE ARRIVAL TO CLASS is discouraged. It disrupts the other students and the instructor and if repeated, may be basis for barring from the class. If you absolutely must arrive late, enter quietly from the back and sit in the back. Only the persons enrolled in that class and section can attend the lecture.

NOTE ON CELL PHONES AND THE LIKE: Cell phones are great technology and it is great to have one with you for emergency. (Campus police: 815-753-1212). However, please, turn off your phones and other noise-making devices as a courtesy to others, and do not distract yourself by reading and sending text messages. You must turn off cell phones and any other communication devices and put them away during tests and quizzes.

Remember, tutors are not infallible. They do not take this course and may be interpreting some problems differently. If you get a private tutors, inquire about their chemistry background. I am not infallible either, but at least I have the ability to let the class know of my error. With a tutor, who taught you incorrectly, you are on your own.
