CHEMISTRY 101, General Chemistry Spring 2014
Instructor: Ms. Laura Benton,
[email protected] Class Times: MWF, 11:00 – 11:50 AM, Chapman 211 Course Prerequisites: Math 110 Group Office Hours: Monday, 1:00 – 2:00 PM AND Wednesday, 12:00 – 1:00 PM in the Chemistry Resource Center (Kenan Labs C147). Bring your questions about in-‐class problems and homework for the week, and we will work on them together. There are no office hours (group OR individual) on exam days. Individual Office Hours: Monday, 2:00 – 3:00 PM AND Wednesday, 7:30 – 9:30 AM in my office, Kenan Labs C147E. These hours are for individual meetings to discuss grades, study techniques, etc. There are no classes scheduled from 7 – 8 AM, so anyone with conflicts at other times should plan to come to the Wednesday morning hours. Class Website: Our class website is at http://sakai.unc.edu. Please check daily for updates. In addition to powerpoints and additional resources, there is a forum for you to pose any questions you have on content. The more questions you ask and answer, the better this resource will be. Required Textbook: Brown, LeMay & Bursten. Chemistry, the Central Science, 12th edition. The full solutions manual is available in the Chemistry Resource Center. Please read all sections that we cover in class. Required Equipment: A good scientific/graphing calculator. Please make sure you have both a backup calculator and extra batteries, especially during exams. You may not use any calculator during exams with wireless, network, or texting capabilities (no cell phones, iPad, iPod, etc). You may not share calculators during exams. Attendance: Not required, but highly recommended if you wish to be successful. Communication: Please come to office hours if you have questions about course content or your performance. The early morning office hours on Wednesday are there specifically to avoid conflicts with other classes. If you are unable to attend scheduled hours for some reason, please post content-‐related questions on the sakai forum. If you do email me, please allow for a 48 hour turn-‐around time on emails, and note that by law, I cannot discuss grading issues over email. I am unable to answer emails the day before an exam.
Extra Help: The Chemistry Resource Center, located in Kenan Labs, Room C147, is open for free tutoring Monday – Thursday, 2:00 – 8:00 PM. The Learning Center at UNC (learningcenter.unc.edu/) has a plethora of free resources, including tutors for specific classes, as well as information about studying, test taking, etc. A list of tutors for hire is posted on the UNC chemistry website (chem.unc.edu), and I have some sources as well. If you’re starting to struggle, seek help ASAP. If you fail an exam, you are required to meet with me to discuss your grade. This meeting is not so that I can fuss at you, but rather so we can figure out where you’re struggling and strategize ways you can improve. Technology: You may use laptop computers to take notes, but please stay on-‐task. If your cell phone rings in class, I get to answer it. Please keep it on silent or switched off. Texting during the lecture distracts your classmates, so please keep all cell phone usage to a minimum.
Grading
Homework: The problems provided as homework in this syllabus will not be collected or graded. However, I highly recommend that you work through these problems multiple times for your own understanding. A solutions manual is available in the Chemistry Resource Center (Kenan C147). Please do not remove the manual from the resource center. Exams: Your grade is based on three hourly exams and one comprehensive, multiple-‐choice final. If you have concerns about test-‐taking, please consult the Learning Center. Please bring your one-‐card to all exam sessions. Failure to bring your one-‐card may result in a zero on that exam. The hourly exams will be on January 31st, March 3rd, and April 11th during normal class times. The final will be on Tuesday, May 6th, at 12:00 PM. Important notes about exams: The hourly exams are optional. The final is required. There are no make –up exams. No exams will be given early. Re-‐grading: A random selection of exams will be photocopied prior to their return. You may request a re-‐grading of any exam, but note that any request must be applied to the whole exam, not just one question. Your score after re-‐grading therefore could be higher OR lower than your original score. If you choose to have your exam re-‐graded, you must turn in the exam, stapled to the required cover sheet (found on Sakai), no later than one day before the subsequent exam. Cheating and plagiarism: It is against the UNC honor code to cheat by any means, including looking on someone else’s paper, using cheat sheets/cell phones, passing notes/talking during an exam, etc.
Policy adopted by the faculty of the Department of Chemistry on Sept. 9, 1977: "Since all graded work (including homework to be collected quizzes, papers, mid-‐term examinations, final examinations, research proposals, laboratory results and reports etc.) may be used in the determination of academic progress, no collaboration on this work is permitted unless the instructor explicitly indicates that some specific degree of collaboration is allowed. This statement is not intended to discourage students from studying together or working together on assignments which are not to be collected.” How your final letter grade is determined: • If you take all three hourly exams, the lowest exam grade is dropped, and your final semester grade = 0.25 hour exam + 0.25 hour exam + 0.50 final exam OR = 0.17 hour exam + 0.17 hour exam + 0.66 final exam. I will take whichever one is higher. • If you take two hourly exams, your final grade = 0.17 hourly exam + 0.17 hourly exam + 0.66 final exam. • If you take one hourly exam, your final grade = 0.17 hourly exam + 0.83 final exam. • If you take no hourly exams, your final semester grade is whatever you score on your final. Those who choose this option rarely earn the grade they want (usually failing). • There will be no changes to the way grades are calculated under this system. You may not, for example, take the hourly exams and then ask for your final exam score to count as your final grade. • The numerical ranges and their corresponding letter grades are listed below. There are no curves for individual exams. I reserve the right to curve final grades, but only at the end of the course and only if the final class average falls below the C range. Letter Grade Numerical Range A 93 – 100 A-‐ 90 – 92 B+ 87 – 89 B 83 – 86 B-‐ 80 – 82 C+ 77 – 79 C 73 – 76 C-‐ 70 – 72 D 60 – 69 F Below 60
