Chemistry-4 is a rigorous theoretical course in college-level chemistry intended to prepare students for university-level courses in chemistry as required for majors in science, medicine or engineering. Process skills such as analytical thinking, problem solving, making sense out of data, and writing/communication are essential. Depth of coverage and intellectual challenge are more important than breadth of coverage. Therefore I have adopted the following goals for this course:
Grades in the course will be broken down as follows:
Tests: 40%
(1 per quarter)
Quizzes: 30% (4 - 6 per quarter)
Labs:
30% (4 - 6 2-hr labs per quarter)
The schedule at the end of this introductory material shows what to expect for each unit. Specific dates are not given in the interest of maintaining flexibility. The number of hours of class time for each unit is indicated as a goal. Also in the schedule is recommended Memory Work which are items that you should commit to memory.
For each unit you will be required to complete a brief Outline of the important points in the reading assigned for that unit. This Outline must be separated into the sections used in the chapter. Sometimes one or two entries on the Outline will be sufficient for a given section. For other, more complicated sections you will need to use your judgment as to what the most important ideas and problem-solving techniques are. Keep Outlines brief! This is not meant to be a burden but rather a way to encourage you to prepare thoroughly for class. Outlines should be completed by the first day of a new unit: you must read ahead!
A tip about reading textbooks: they are not novels. In a novel you typically read a passage once with full comprehension. The action carries you forward through the text. Textbooks build sequentially in each chapter and you will at times need to read a section several times—and work through its examples on paper— before you can move on to the next section. Be self-aware and check in with yourself: Did I understand that passage? Could I solve problems based on it?
Each unit has a Problem Set that consists of questions and problems from the ends of the chapters. At times I will assign problems from supplementary material for the Problem Set. These problem sets will be approached in several ways:
Both Outlines and Problem Sets count as Homework. Homework is not collected, graded, or checked off. Instead, you must keep Outlines and Problem Sets neatly in a dedicated binder. At the end of the quarter you must show this binder to the instructor for a Homework Quiz grade. It will be graded on completeness and organization.
The date of the Homework Quiz will be set whenever we begin a new unit. The Homework Quiz will draw on problems directly from your homework and will be short.
Test dates will be near the end of each quarter.
Tests will be comprehensive and will be designed to be completed in one hour.
Labs will be offered four to six times each quarter. Lab assignments will vary in scope but at minimum will require completion of pre-lab work by the first day of work and completion of post-lab questions. Two to three times each quarter you will be required to submit a full formal lab report (format available separately). A portion of your lab grade will depend on your diligence in keeping a good scientific lab notebook. Required for this purpose is a permanently bound ruled notebook. In this notebook you will write your lab procedures, lab notes and data while you work in the lab. A handout is available separately that describes how to make good use of your lab notebook.
Study Groups are strongly recommended. During the first week of class you will form study groups of 3 - 4 people. Make a regular time to meet and work on Chemistry together. Working together makes tackling the difficult material of this course a bit more manageable. These groups will continue to work together during class. Re-shuffling of Study Groups will be allowed, if necessary.
Frequently I will ask students to present problems at the board. Presentations will consist in writing out the detailed solution to a problem on the board and explaining how you came to it to the class. The other members of the class are active participants in the process and are expected to ask questions and demand that the presenter justify his or her work. Problem presentations will be a frequent part of this course and will usually precede a Homework Quiz.
In this course our motto is FIO (an acronym that I leave to the reader: you will figure it out if you think about it for a bit).
It is important that you evaluate yourself frequently as you work to find out what you have learned. Try repeating to yourself the contents of class discussions. Even better, go over the concepts and problem-solving techniques with your study group: communicating something you have learned forces you to organize your thoughts about it. When you do so, you learn it better yourself. This is true also about writing in the course. Your lab reports and the answers to lab questions are learning opportunities. When you explain what you have learned in writing you often find that you have not learned it as well as you thought you did. Go back and learn it properly and your writing will improve.
