SUPPLEMENTARY READINGS / MATERIALS: Tro, Nialdo, Introductory Chemistry, Pearson/ Prentice Hall Zumdahl and DeCoste, Introductory Chemistry: A Foundation, Brooks/Cole The McGraw-Hill Dictionary of Chemistry, McGraw-Hill, 2203 OTHER REQUIREMENTS: 1. A calculator is required. Calculators attached to cellular telephones may not be used during exams.

4 ASSESSMENT MEASURES: from the textbook not more than 5% Quizzes not more than 15% Class participation not more than 5% Unit Examinations (3 or 4) 50-65% Laboratory work 20-25% Final Examination (Comprehensive) 10-20% Writing assignment not more than 5% GENERAL GRADING POLICY: 1. A missed exam will result in a grade of zero for the exam. Make-up examinations will be administered according to the instructor s grading policy. Alternately, the instructor may provide for substitution of the student s final examination grade for the grade on a missed exam. 2. Academic dishonesty on the part of the student will result in a grade of zero on the given paper, quiz, or examination. A grade of zero resulting from academic dishonesty will not be replaced, or omitted, regardless of any other provision in the instructor s grading policy. The student should read the Bergen Community College statement on academic integrity that is to be found in the college catalog. 3. At the discretion of the instructor, the grade on the final examination may be substituted for the lowest unit exam grade for the purpose of calculating the course grade provided that the final examination grade is higher than the lowest unit examination grade. 4. A passing grade in the course requires acceptable levels of work in both the lecture and the laboratory sections of the course. Acceptable levels of work will mean a score of 60% or greater. 5. A writing assignment will be given unless essay questions are included in the unit examinations. This may involve chemistry topics in the news or the analysis of one or more journal articles. The writing assignment will count no more than 5% of the course grade. 6. Laboratory: Students will be required to complete pre-laboratory assignments and laboratory reports for each laboratory class. Laboratory reports will be due at the laboratory session following the one in which the experiment is completed. At the instructor s discretion a late laboratory report may be accepted for a reduced grade. No student will be permitted to submit more than two laboratory reports late during the semester. A missed report counts (grade = 0). Instructor s will make an effort to assist a student in making up a missed laboratory class but the possibility of making up a missed laboratory depends on scheduled classes and space in those classes. The laboratory grade will be based primarily on average of the student s laboratory report grades (90%) and the student s level of completion of the pre-laboratory assignments (10%). The student s laboratory grade will count 20% to 25% of the course grade. 7. Instructors may make small modifications to the General Grading Policy for the course and will give each student a copy of the grading policy for the given section.

5 INSTRUCTOR S GRADING POLICY: Each Instructor will provide a written copy of the grading policy for the given section of the course. ATTENDANCE/LATENESS POLICY: All students are expected to attend every meeting of the course punctually. The individual instructor s attendance/lateness policy will be provided, in writing, at the beginning of the course. Attendance will be kept by the instructor for administrative and counseling purposes. Students who are late to the laboratory class and have missed the instructions, including safety instructions, for the laboratory experiment may be refused permission to perform the experiment. OTHER POLICIES: 1. The use of portable electronic devices such as pagers and cellular telephones is not permitted while class is in session. Students carrying such devices should silence them before entering the classroom or laboratory. 2. Calculators will be required for the course and students are responsible for bringing a calculator to all quizzes, exams, and laboratory classes. The calculators used for exams cannot be calculators attached to cellular telephones nor can they be graphing calculators. STUDENT AND FACULTY SUPPORT SERVICES: 1. Students are encouraged to get assistance with any and all aspects of the course in a timely manner. 2. Students should make note of the instructor s office hours and should see the instructor for assistance with understanding concepts or problem solving. 3.
