Chemistry 113, Spring 2007
Assignments
Be sure to read Surviving Chemistry.
- ASSIGNED READINGS: We will cover most of chapters 1 through 12 in Chang: Chemistry.
My classes are designed to help PREPARED students. It is CRUCIAL that you read each chapter once
BEFORE we begin discussing it in class.
Reading assignments are on the calendar. Read the entire chapter unless the schedule says to omit specific sections.
- ASSIGNED PROBLEMS: I do not assign or take up homework, but problem solving is the most important activity in your study.
• Practice Exercises (within chapter): Work all Practice Exercises when you encounter them during your first reading the chapter. Check the answers at the end of the chapter, but do not look at the answers until you cannot find anything wrong with your answer.
• Questions and Problems (end of chapter): Each named section of Questions and Problems corresponds to the section of the same name in the chapter. If you have difficulty with a problem, consult the corresponding section of the text.
BEST:
Work all even-numbered Problems in each section of Questions and Problems at the end of the chapter. Also pick and work some of the Additional Problems.
MINIMUM:
Work the first three even-numbered problems in each section. This is the absolute minimum amount of problem solving to do if you hope to pass this course.
USING ANSWERS: For all even-numbered problems,
check your answers in the back of your text, but do not look at the answers until you cannot find anything wrong with your answer.
- IMPORTANT ADVICE: Work on chemistry every day, or at the worst, every other day. Do not let the course
slide between classes. From Friday to Monday is a long time --
long enough to require extra work to recover what you've
forgotten. With regular effort, you keep moving forward, and you
don't waste valuable time recovering from lapses, Try to put at least a little
time into your study of chemistry every day.
- NEED MORE PROBLEMS AND GUIDANCE? Try the lessons at ChemReview Tutorials.
Schedule (VERY tentative)
I will
develop and revise the schedule as the course proceeds.

NOTICE
It is possible to improve your grade significantly with the third exam and the final exam. BUT history shows that the majority of students who have a failing average after two exams end up grades of D or F. To avoid a low grade on your permanent transcript, you may withdraw by March 23 (spring 2007) with a grade of W, and without my approvaI. I cannot approve withdrawals after March 23. If you do decide to withdraw, you may continue attending class in order to be better prepared when you take the course again. |
