Fall 2009 Instructor Martín G. Zysmilich, Assistant Professor Dept. of Chemistry – Samson 306 – (202) 994-4726 email@example.com Meeting time and place Section 10: MW 2:20 – 3:10 pm – 1957 E 213 Section 11: MW 3:55 – 4:45 pm – 1957 E 213 Office Hours: MW 3:10 – 3:55 pm – 1957 E 213 Recommended Text Chemistry in Context, Applying Chemistry to Society, 6th Edition; L.P. Eubanks, et al.; McGraw-Hill, Boston, 2009. Course Description This course will focus on several topics that have been making the headlines in the science section (and sometimes in the main section) of major newspapers and other relevant mainstream publications. The main objective of the course is to provide students with the necessary tools and skills to understand the chemistry behind scientific issues in the area of environmental chemistry and energy production, as well as their sociopolitical implications. Students will learn about the origin of common pollutants, their relationship to the energy needs of humans, their short and long-term effects on the environment and the solutions that science, and more specifically chemistry, have already fashioned and would produce in the near future. Learning Objectives After taking the class students should be able to: - Appreciate the diversity and complexity of phenomena in the natural world; - Identify regularities and patterns in Nature that may indicate fundamental unifying principles and laws; - Evaluate scientific information and apply critical judgment to determine whether the data and observations support a hypothesis; - Understand the strengths and limitations of the scientific process; - Know how to distinguish the products of scientific enquiry from the products of other types of inquiry; - Establish connections between the scientific enterprise and everyday life; - Recognize that science is not just a body of knowledge, but is also a set of skills. Method of Instruction Students are required to attend two lecture sessions and one laboratory session per week. Attendance to both lectures and laboratory is mandatory. Reading assignments from the textbook and from related websites, as well as short "research projects" will be given for some units. Reading assignments from the textbook are optional. Reading assignments posted on Blackboard are required. The material covered in these assignments will be included in the exams. Laboratory Students taking Chem003 must complete the laboratory requirement concurrently. In order to obtain a passing grade in the course, you will need to complete the laboratory requirement and obtain a passing grade for it. Blackboard You need to be officially registered for Chem 003 in order to access the Blackboard site (http://blackboard.gwu.edu) for Chem 003. This site includes the reading assignments for each lecture, as well as links to related newspaper articles, audio clips from NPR reports, the Environmental Protection Agency (EPA), and others. These sites not only focus on the scientific aspects of the topics discussed in class, but they provide a more global political and social point of view. The outline from each PowerPoint presentation used during lectures will be made available on Blackboard before the topic is presented. You should preview the material before coming to class. Practice problems, similar to those found in the exams, will also be posted on Blackboard. You encouraged to review and work on these problems, ask questions during lectures, submit questions via e-mail, and attend office hours whenever needed. E-mail policy In order to protect students’ privacy, students should e-mail their professor and/or teaching assistants from their official GW accounts. E-mails received from other providers (Gmail, Yahoo, Hotmail, etc.) will be ignored and deleted. 1 Chem 003 – Fall 2009 Absences No student will be excused from taking an exam at the schedule time without the prior permission from the instructor. If you believe that you have a legitimate reason for requesting an excused absence, contact the instructor before the exam either in person, by phone or by e-mail. The student should provide suitable documentation of the valid excuse. Slips from visits to Student Health Services are not acceptable. A grade of zero will be given for an unexcused absence. If, with a valid reason, you miss one of the exams, a comprehensive make-up exam on December 7 is your only opportunity to make up for the missing grade. You cannot make-up more than one exam. You may be excused for religious holidays that are recognized by George Washington University. It is your responsibility to inform the instructor of the holidays that you plan to observe prior to September 15. Method of Evaluation There will be two non-cumulative multiple-choice exams (October 14 and December 2). If you want to improve your grade in one of the two exams, you can choose to take an optional comprehensive make-up exam on December 7. In order to be allowed to take the comprehensive make-up you need to receive at least 40 points on the exam you wish to replace. The grade you receive on the comprehensive exam will replace your lowest test score, even if it is lower than your original exam grade. Grading Two one-hour exams (2 x 100)............... Lab reports.............................................. Extra Credit............................................. 80% 20% 5% Passing grade In order to pass this course you need to obtain at least 120 out of the 200 possible points for the exams, and at least 60 out of the 100 possible points for the lab. Grades are not negotiable. The final percentage grade is calculated by multiplying your total exam grade by 0.40, and adding it to your lab grade multiplied by 0.2, plus the extra credit points multiplied by 0.05, rounded up or down to the closest integer: %grade = (E1+E2) x 0.40 + Lab x 0.20 + XC x 0.05 For example, if you obtain a 75 in the first exam (E1), 86 in the second (E2), 90 in the lab (Lab), and 65 extra credit points (XC), your final percentage grade will be (75+86) x 0.40 + 90 x 0.20 + 65 x 0.05 = 85.65 (rounded up to 86). If the sum of your grades for exams 1 and 2 (E1+E2) is less than 120, your final grade will be F, no matter what your lab grade is or how many extra credit points you have obtained (see below). If your lab grade is less than 60, your final grade will be F, even if you had received a passing grade in the lecture exams. Letter grades will be assigned according to the following scale: 100 ≤ A ≤ 95 < A- ≤ 90 < B+ ≤ 85 < B ≤ 80 < B- ≤ 75 < C+ ≤ 70 < C ≤ 65 < C- ≤ 60 < F Grading problems or concerns regarding an exam should be discussed with the professor within ten days from the date grades were posted. Grading problems or concerns regarding laboratory assignments should be discussed with the laboratory coordinator within ten days from the date the graded assignment was returned to the student. Extra Credit The Classroom Performance System (CPS) by eInstruction will be used to assign extra credit. It is your responsibility to bring your response keypad to every lecture and to keep it in working condition. Extra credit points cannot be made-up even for excused absences and/or keypad malfunction. Please, read the eInstruction information posted on Blackboard. Extra Credit Policy: - Extra credit points do not count towards the 120 lecture points necessary to pass this course. The extra credit is only used to boost your grade once you passed the course. - During every lecture 1-3 questions related to material covered in previous lectures (as a review) and/or the current lecture (to emphasize concepts) will be posted. - These questions will be up on the screen for different times according to their degree of difficulty. - During the time each question is shown, each student should select the answer s/he considers correct (A, B, C, or D). Discussing the question with a classmate in class is allowed and encouraged. - You will then deliver your answer by using your registered eInstruction response pad. Using a classmate's response pad will be considered an act of Academic Dishonesty. - The number of extra credit points (XC) will be computed with the percent of questions correctly answered (%R) as follows: • If 85% ≤ %R ≤ 100%, your XC = 100. • If 26% ≤ %R ≤ 84%, your XC = %R+15. • If 0% ≤ %R ≤ 25%, your XC = 0. 2 Chem 003 – Fall 2009 Academic Integrity The University community, in order to fulfill its purposes, must establish and maintain guidelines of academic behavior. All members of the community are expected to exhibit honesty and competence in their academic work. Incoming students have a special responsibility to acquaint themselves with, and make use of, all proper procedures for doing research, writing papers, and taking examinations. Members of the community will be presumed to be familiar with the proper academic procedures and held responsible for applying them. Deliberate failure to act in accordance with such procedures will be considered academic dishonesty. Acts of academic dishonesty are a legal, moral, and intellectual offense against the community and will be prosecuted through the proper University channels. Copies of the University Code of Academic Integrity can be obtained from the following officers: all department chairs, all academic deans, the Registrar, and the Vice President for Academic Affairs. Student Conduct All students, upon enrolling and while attending The George Washington University, are subject to the provisions of the Guide to Student Rights and Responsibilities, which outlines student freedoms and responsibilities of conduct, including the Code of Student Conduct, and other policies and regulations as adopted and promulgated by appropriate University authorities. Copies of these documents may be obtained from the Office of the Dean of Students or from the offices of the academic deans. Sanctions for violation of these regulations may include permanent expulsion from the University, which may make enrollment in another college or university difficult. Disability Support Any student who feels s/he may need an accommodation based on the impact of a disability should contact the Disability Support Services office at 202-994-8250 in the Marvin Center, Suite 242, to establish eligibility and to coordinate reasonable accommodations. At a student's request, DSS prepares an individualized letter to professors that verifies the nature of the student's disability and documents the need for auxiliary aids and services and/or academic adjustments. Students are encouraged to meet with each professor early in the semester to discuss the academic implications of the disability as they relate to the specific course and to request accommodation. For additional information please refer to: http://gwired.gwu.edu/dss/ All students needing special accommodations for the exams (additional time, scribe assistance, etc.) should submit an accommodation request online AT LEAST seven days before each test. If the request is submitted after this deadline, the student will have to take the test with the rest of the class and in the allotted 50 minutes. No exceptions.
