Goals

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:


Instructional Techniques and Assessment

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. 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 will be submitted through Google Classroom. 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! I require this work to encourage you to prepare thoroughly for class. It’s up to you to make it useful to you. You may never look at it again but the fact that you made it can help you to learn and to read carefully. 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. The problems are a tool you will use to learn new material: you will not immediately know how to solve each problem no matter how well you pay attention and take notes in class. These problem sets can be approached in several ways:

  1. You will work independently to solve the problems using only your brain, the text, a calculator and paper and pencil.
  2. You will work in study groups outside of class to help one another to solve the problems. Use this time not to copy another student’s solution but to compare notes about the best way to get to a solution.
  3. You will come to your teacher during Advisory to work on problems so that you can check solutions and ask questions.

Outlines will be checked for completeness and count for 1/10 of a quiz grade. Problem sets will be checked using a homework quiz. Prior to the quiz you will be required to be able to present to the class a solution to a random problem.

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.


Metacognition

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.


Recitation

One of the most important ways to improve your grade in my class is to do well on tests and quizzes. In order to encourage you to come in for help with your preparation I will offer 5% in extra credit points on a quiz if you come in at least once to study in my room during office hours and actively ask me questions. This is a great opportunity to get together with friends to come in and ask questions and study together.

Quotes from Students


“I think this class has made me more of a self-driven learner. Before this year if I was stuck on a problem I would often wait for the teacher to explain it, but now I take the time and do the work to figure it out on my own. I think this has really improved my learning.”

“This class has changed me as a student because I have had to learn how to do more learning on my own and be efficient in my work so I have time to study.”

“This class has made me realize that some subjects are most effectively learned—or even must be learned—simply by applying new concepts through trial and error (e.g., in the problem sets). I have become a more patient learner because of this class, more willing to blunder around in the dark until things make sense, and more appreciative of the time it takes to develop true understanding.”

“Success in fields like Chemistry has less to do with how many facts you can just rote memorize and more with a willingness to study, think about, and eventually understand fundamental systems.”

“This class has changed me as a student because I had to look at things before tests to not fail them.”

“This class has changed me as a student because it has strengthened my ability to solve problems. I have developed new strategies involving looking at problems from different angles and writing down everything I know first. This has carried through to my other classes”
