CHEM 106, Section 001, General Chemistry II, Spring 2017 Lecture: MWF, 9:00-9:50 a.m., Science 18 Workshop: R, 2:00-3:15 p.m., Science 18 Instructor: Eric Glendening, Science 35N, 812-237-2235, glendening@indstate.edu Textbook: Zumdahl, Chemistry, 9 th ed. (Brooks/Cole) Homework: OWLv2 Online Web Learning Version 2 (Cengage Learning) Blackboard: http://blackboard.indstate.edu/ CHEM 106 is the second semester course of a two-semester general chemistry sequence. The course has two prerequisites: successful completion of CHEM 105 with a C grade or higher, and concurrent enrollment in the CHEM 106L laboratory. The CHEM 105/106 sequence serves as a prerequisite for more advanced courses, such as Organic Chemistry (351, 352) and Analytical Chemistry (321). Lectures: Regularly attend lectures. Your attendance is essential to perform well in (and usually to pass) this course. Each lecture will focus on a different topic. If you must miss a class, recognize that you are responsible for getting a copy of the lecture notes from a classmate and catching up with the class. Workshops: Students are required to attend a workshop every Thursday. Students work in groups of three or four to complete problem solving activities. Bring your calculator, lecture notes, and a pencil to these workshops! Activities completed in the workshops will be graded and will contribute 15% of your raw grade. OWLv2 Online Web Learning: You will be assigned problems to complete on this online electronic homework system. Create an OWL account for yourself by clicking the OWLv2 Login link on the course Blackboard site (given above). The account is free for three weeks. You must enter an OWL access code within three weeks to continue using the software for the entire semester. E-mail me if you have any problems. An OWL access code is available for purchase at the ISU bookstore (bundled with the unbound copy of the textbook for $185) or online at http://www.cengagebrain.com (enter ISBN number 978-1-285-18545-3 for OWL with a digital copy of the textbook for $129). Every student must have his or her own access code to use OWL; OWL codes cannot be shared. The OWL access code is valid for 24 months. OWL assignments will be presented to you in sections, each section corresponding to a section of the textbook that you have been assigned to read. You receive credit (points) for each of the problems, or series of problems, completed in the assignment. OWL problems can be repeated up to ten times in an attempt to maximize your score, or just for practice.
You will receive credit for OWL assignments completed and submitted to me by the due date. OWL assignments are always due at 9:00 am two class periods after the class in which the assignments are made. A total OWL score that contributes to your final grade will be calculated by scaling the total number of OWL points that you accumulate by 1.2. Your OWL score will not, however, exceed the total OWL points possible. The 1.2 scaling allows you to receive full credit for OWL assignments by successfully completing five out of every six OWL problems. OWL assignments will contribute 10% of the raw grade. Quizzes: A ten-minute quiz will be given during the last lecture period of every week, except on the first week, on exam days, and on study week. These quizzes will collectively contribute 10% of the raw grade, with the two quizzes of lowest score discarded. If you expect to miss a quiz, let me know. We will arrange a time for you to take the quiz early. Quizzes cannot be made up after they have been given in class. Exams: There will be four hour exams and a final exam. The four hour exams will be given during the 50-minute lecture periods on Fri Feb 10, Fri Mar 10, Fri Apr 7, and Fri Apr 28. Mark your calendars now! These exams will cover course-related material, including topics discussed in lecture and in workshop, textbook reading, quizzes, and assigned problems. The four exams will each contribute 13% of the raw grade. The final exam will be comprehensive and contribute 13% of the raw grade. The final exam will be given at 8:00 a.m. on Wed May 10. Improvement Incentive: Although the topics that you learn in chemistry will become increasingly challenging, it is possible to improve your performance as you proceed through the course material. This is principally accomplished by learning from your mistakes and committing extra effort to study material in which your understanding is weak. As an incentive to make the effort to improve your performance during this course, you will receive for each hour exam a bonus equal to 50% (rounded down) of the difference between the next exam score and the current exam score. For example, if you get a 70 of the first hour exam and an 85 on the second hour exam, a 15 point improvement, you will receive a bonus of 50% of 15 points, which is 7 points (rounded down). Your first hour exam score of 70 will be effectively replaced then by a score of 77. A bonus will be added to the score of each hour exam if the next exam score is higher. The final exam score will be used when calculating the bonus for the fourth hour exam. There is no opportunity for a bonus on the final exam. Attendance: Your attendance in lectures and workshops is expected and will influence your final grade for this course. Suppose T is the total number of class meetings during the semester. A student who attends (or is excused from) a total of N meetings will be assigned an attendance scale factor: N 2 attendance scale factor 100% (but not larger than 100%) T
This scale factor will be used in the calculation of your final grade, as described below. Note that students may be excused from a lecture or workshop by informing me of the reason for the absence either prior to the lecture or workshop or by noon on the day of the missed class meeting. A brief e-mail to me will usually suffice. Note that the +2 in the calculation of the scale factor effectively allows a student to have two unexcused absences with no penalty. Grades: A raw grade will be calculated for each student based on their performance on workshop assignments (15%), OWL homework (10%), quizzes (10%), hour exams (52%), and the final exam (13%). A final grade will be calculated by multiplying the raw grade by the attendance scale factor described above. Letter grades will be determined according to the following scale: Letter Grade Final grade (%) A+/A/A 88-100 B+/B/B 70-87 C+/C/C 58-69 D+/D/D 50-57 F <50 Sample Grade Calculation: Sarah finishes CHEM 106 having earned 213 of 268 OWL points and 326 of 365 workshop points, and having completed nine quizzes, four hour exams, and the final exam. The gradebook entries for Sarah show the following: component Points fraction (f) weight (w) weighted fraction (w f) OWL 213 1.2 256/268 = 0.954 10% 9.5% workshop 326 326/365 = 0.893 15% 13.4% quizzes 8, 8, 9, 6, 7, 7, 10, 9, 8 59/70 = 0.843 10% 8.4% hour exams 84(+2), 89, 73(+6), 85 339/400 = 0.848 52% 44.1% final exam 77 77/100 = 0.770 13% 10.0% *raw grade* 85.4% Note that Sarah s OWL points are scaled by 1.2, and her two lowest quiz scores are dropped. Sarah was absent nine of the 58 times the class met. She attended class 49 times and had three excused absences. Her attendance factor is (49+3+2) / 58 = 0.931. Sarah s final grade is her attendance factor times the raw grade: 0.931 85.4% = 79.5% for a B. Dropping CHEM 106: If you drop CHEM 106, the registrar will also automatically drop you from the CHEM 106L laboratory. Beware: if you drop CHEM 106+L, your course load will be reduced by four credit hours, which may drop you below the 12 credit hour requirement for full-time student status. Calculators: Bring a calculator to class on quiz and exam days and to all workshops. Your calculator need not be expensive ($10-$15 is usually sufficient) but it should have the capacity to take square roots and logarithms (log, ln) and to handle exponentiation and exponential
notation (e x, 10 x, y x ). If you forget your calculator, you may be able to check one out in the Chemistry Department Office (Science 35) using your student ID. Laptops: Use of laptops is not allowed, unless otherwise directed. Cell phones: Cell phones should be silenced and put away. Office Hours: I am generally available to answer questions most afternoons. Feel to stop by my office then. If you favor an appointment, one can be arranged. Supplemental Instructor: Juan Nysschen (jnysschen@sycamores.indstate.edu) will serve as the supplemental instructor for CHEM 106. He will work with you in our Thursday workshops and will lead two review sessions each week, at times and locations to be determined. Juan, our SI, works closely with me to maximize your learning. He knows the course content, reinforces key points of learning, and can assist you with course material for which you may be uncertain. Your participation in Juan s supplemental instruction sessions is strongly encouraged. Science Help Center: Assistance with your chemistry coursework is also available in the Science Help Center. The Center is located on the first floor of the Science Building (Room 115) and is open approximately 25 hours per week. The Center is staffed by undergraduate chemistry students who are currently enrolled in upper-division courses. CHEM 106L Laboratories: Labs do meet the first week of classes!
