2 Attendance: Attendance is a critical factor associated with performing well in this course. I am here to teach you chemistry. This process is more efficient if you are here to learn from me. A strong correlation exists between good attendance in class and good performance in the course. Students who attend lectures, in general, have a much higher chance of doing well than those who do not attend lectures. College policy states that you may be dropped from a course for excessive unexcused absences which total more than one week of classes. Please do not cause me to enforce this policy. It is my hope that you enjoy this class so much that you will not want to miss class. While you may find this class challenging, you also may have some fun. Consider yourselves forewarned of the potential fun with chemistry that lies ahead!! Grading: Three 100 points each (lowest score dropped) 35 % Five POP Quizzes (taken from homework problems) 15 % Laboratory (Lab Reports + Lab Quizzes) 25 % Cumulative Final Examination 25 % TOTAL 100 % Laboratory: In order to pass this course, you must pass (60% score or better) the laboratory component of the course. Each lab report is due at the beginning of the lab class one week after the laboratory experiment has been completed, unless otherwise indicated, and will be worth 10 points. If the document for an experiment contains a Prelaboratory section, it will also be due at the beginning of the lab on the day on which the experiment is performed. You will not be allowed to perform a given experiment unless the Prelaboratory assignment is completed and turned in prior to the start of that experiment. Two of the lab reports will be formal reports, completely written by the experimenter according to guidelines that will be discussed in the laboratory section. Other assignments, labeled MISC XXXX in the schedule below (where XXXX represents a four-digit number), are also to be completed. Lab quiz questions will be taken directly from the Pre-laboratory and MISC assignments. You must wear eye protection, closed-toed shoes and a lab coat during the laboratory period. It is highly recommended to leave your safety glasses or goggles and lab coat in your laboratory drawer, so they will be there each time you come to lab. You will not be allowed to perform any experiment without appropriate attire and will be asked to leave with no option of making up the lab. You will simply lose those points toward your overall grade. No eye protection will be loaned to you from the department, so do not bother to ask. Simply come to lab prepared. Tips for Success: As mentioned above, CHEM 170 is a course designed to prepare you to take the more rigorous General Chemistry sequence. No previous knowledge of chemistry is assumed of the student; however, competency in basic algebra skills is a necessity. If one particular area can be identified in which students struggle in a chemistry class such as this one, it is in the application of mathematical methods to solve chemical problems. For the majority of students, in order to do well, you must attend lectures. Furthermore, not only should you attend lecture each day, but you should come to lecture prepared. Do the assigned reading before lecture. Chemistry is a discipline best learned by working problems, not by simply memorizing facts. Do the homework, but work more problems than the few found on the syllabus. Studying with others is beneficial to many students. Consider forming a study group. The most important advice I can offer is: Do not fall behind in this class.
3 Late Policy: Lab assignments will be penalized with a 10% reduction for each day late. No assignments beyond one week late will be accepted. No exceptions will be made. Period. Make-up Policy: No exams, quizzes, or laboratory experiments can be made up, if you are absent on the day of that activity. Academic Honesty: Participants found to be cheating on exams will receive a zero for that exam, and, depending upon the circumstances, may be dropped from the course. Plagiarism on laboratory reports will also not be tolerated. Appropriate measures will be taken in any offense of dishonesty. Learning Disabilities: Southwestern College recommends that students with disabilities discuss academic accommodations with their professors during the first two weeks of class. This syllabus and other course handouts are available in alternate media upon request. Students with learning disabilities should contact the Disability Student Services at (619) for evaluation and provision of services for special needs you may possess. Other Issues: Items such as cell phones, digital music players (e.g. ipods, MP3 players, etc.), personal digital assistants (e.g. BlackBerry, Sidekick, iphone, etc.) must be turned off during class time. You may use them before and after class or during the break between lecture and lab, but at no time should they be distracting elements during class time. Violations may result in dismissal from class, with no opportunity to make up the lost time. Period. Homework: The homework problems assigned in the schedule will not be graded but are for the purpose of helping you to learn the material. The pop quizzes will be based directly on assigned homework problems. It is highly recommended that you do more problems than these. There is a strong correlation between success in a class such as this and the number of homework problems solved. I strongly urge you to work these problems (and more), although they won t be formally graded. This will help to ensure your success in this course.
