Email: mmbrooks@umd.edu (for personal email messages not related to class) Chem131sie@gmail.com (Please use this email address for course questions. I get upwards of 100 emails per day in my University account and your message may get lost) Contact information for TAs: Natalia White: nwhite@umd.edu Office hours: By appointment Required Textbook: Chemistry: A Molecular Approach by Nivaldo J. Tro (3rd custom edition for UMD)-­‐ A copy of the text is on reserve in the Chemistry Library. Also Required: Mastering Chemistry access key: This semester, we will use the Mastering Chemistry system for homework. You need a Mastering Chemistry access code to gain access to the website and complete assignments this semester. If you purchased your text in the bookstore, the Mastering Chemistry access code should have been packaged with your text. If you do not have a code because you purchased your text elsewhere, you must purchase a stand-­‐alone code. These codes are available at the campus bookstore, but you can also purchase a code here: Important dates to remember: •

Last day for schedule adjustments: September 14 Last day to drop with a "W": November 9 Thanksgiving recess: November 26-­‐29 Last day of classes: December 11 Final exam: TBA Grading Homework: 11 assignments (lowest score will be dropped) at 10 points each: 100 points Exams: 3 exams at 100 points each: 300 points Final Exam: 1 final (date tba) at 200 points: 200 points Total: 600 points The course will be graded purely on a points system. If you receive 90% of the points, you are guaranteed an “A”, 80% “B”, 70% “C”, etc. Work hard and you will be rewarded with the grade you deserve. Homework To register for the online homework section of the course, follow the directions on the “MasteringChemistryRegistration.pdf” document on the ELMS (Canvas) page under “Files” folder. You will need the course code, which is: MMBrooksFall2015 There will be 11 homework assignments this term that you must submit. Each assignment will contain at least 10 questions. Each assignment is worth 10 points total. Assignments will be released on Sundays and will be due the following Sunday at 11:55 p.m. I have given you extra time for the first assignment to allow time to register and acclimate to the Mastering Chemistry environment. Do this as soon as possible. The assignment entitled “Introduction to Mastering Chemistry” will be available for the entire semester, and will NOT count towards your final grade, however, you MUST complete the assignment in order to drop your lowest homework score. It is there simply so you can familiarize yourself with how to input answers and learn how to use the interface. The Mastering Chemistry system maintains grades for all assignments, and may include this score in the gradebook. However, this score will be discarded at the end of the semester. Exams The in-­‐class exams are tentatively scheduled for October 12, November 9, and December 7. The final exam will be held December 14, the location has not been determined yet. When I find out the location, I will make multiple announcements in class and put an announcement on the ELMS (Canvas) page. •

A scientific calculator is recommended for exams. No electronic devices (other than your calculator) will be permitted during any exam.; If you know you will have a conflict with the dates of the exam, such as religious observances, you must be in touch with your instructor by the end of schedule adjustment (Sept. 14). If you are ill on the day of the exam, you must contact me before the exam to make alternative arrangements. An e-­‐mail or phone message PRIOR to the exam time would suffice. Make up exams will be given only with a valid documented University excuse Course Management System: We will be using the ELMS system (by Canvas) as our course management system in this course. If you are not familiar with ELMS, I strongly encourage you to go to: elms.umd.edu during the first week of class and log onto ELMS using your directory ID, which is the same as your email username and password. After logging in, Click on CHEM 131 to enter the site. You can monitor your grades, and download handouts from the site. Course Announcements: I will post all announcements on ELMS/Canvas. Please check the announcements page regularly to keep up with any course announcements. Emailing Etiquette: While the University does not have formal rules and regulations for contacting faculty by email, I have a few rules of etiquette that students need to follow if they expect to receive a response: •
•
•
There should be a salutation, e.g., Dear Dr. Brooks: etc. Please explain your situation using complete sentences. I do not text to you, and expect to not receive "text" messages Please give your full name at the end of the email. I do not respond to "BigStudly@yoyo.com.” A sample acceptable email is shown below: Dr. Brooks: I am a student in your Chem 131 class, but my access to ELMS has been blocked for some reason. Do you know whom I should contact to correct this problem? Thanks, Jane Smith POLICIES of NOTE Course Etiquette: Attendance in class is not required! If you feel that you do not need to come to class, that is your choice (not a wise choice but your choice nonetheless). However, you will be responsible for all announcements and work done in class that day. Please be sure to get notes from another person in class. If you choose to come to class, you must be respectful to others. Please turn off your cell phone. No texting, web surfing, tweeting, Netflixing, Facebooking or any other type of …ing in class. Any cell phones that ring or used for texting in class will be confiscated. You may use a computer to take notes. However, computers cannot be used for any of the “ing” activities listed above. I will ask you to close your computer and take notes with paper and pencil if you are using your computer for other purposes. No newspaper reading or other extracurricular activities are permitted. If you want to work on assignments from other classes, don’t come to this class. Because -­‐ attendance in class is not required! You will be removed from class for these activities. Be on time and stay to the end. Academic Integrity: The University of Maryland, College Park has a nationally recognized Code of Academic Integrity, administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate and graduate students. As a student you are responsible for upholding these standards for this course. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic Integrity or the Student Honor Council, please visit:http://www.studenthonorcouncil.umd.edu/whatis.html. Students are responsible for knowing, understanding and behaving according to the content of the Code. There will be zero tolerance for any violations. Honor Pledge: Students will be required to write and sign on the front cover of each exam the Honor Pledge: “I pledge on my honor that I have not given or received any unauthorized assistance on this examination” More information on the Honor Pledge can be found at: Error! Hyperlink reference not valid. Make-­‐Up Exams: Only students who have university-­‐excused absences are allowed (see Student Handbook). Proper documentation is expected. You must apply for a make-­‐up exam IN PERSON with Dr. Brooks; a copy of your documentation must be provided at this time. Make-­‐up exam times will be scheduled after each exam. Students with learning and/or other disabilities: If you have a disability, please make an appointment to discuss available accommodations to maximize your learning experience in this course. Disability Support Services must document learning disabilities prior to receiving accommodations. Exam Re-­‐Grades: All re-­‐grades are handled by Dr. Brooks. Please don’t ask your TA whether or not you should request a regrade! A re-­‐grade should be requested if: •
•
•
You have the correct answer on your paper and the grader either marked it incorrect (when you are confident your answer is correct) or missed your work. You took a non-­‐traditional approach to solving the problem and you feel your method is valid. All re-­‐grades must be submitted to Dr. Brooks within 1 week after exams have been returned. Re-­‐
grades will be returned in a subsequent Discussion section. Note, however, that the entire exam will be re-­‐graded and this may result in a lower grade. Steps to take for re-­‐grade: •
•
•
•
Assess why you feel you were unfairly graded. On a separate piece of paper write an explanation for why you feel a certain problem was graded incorrectly. Write clearly and be succinct and explicit. Sign your request. DO NOT WRITE ON YOUR EXAM. Staple your explanation to the front of your exam. Turn in your re-­‐grade request to Dr. Brooks. How to get the most out of the class Attendance is strongly suggested for lectures. It is in your best interest to obtain lecture notes and supplementary materials for missed classes. I do not post my notes in ELMS. You are responsible for material covered and announcements made in class whether or not you are in attendance. Questions are welcome during lecture. Please be respectful of others and turn your cell phones off. The problems within and at the end of the chapters are critical to your success in the course. The old saying is ‘practice makes perfect.’ We have found that there is a direct relationship between the number of problems students do and their grade in the class. Working old exams posted on the ELMS website is also highly recommended. Put yourself in a test situation and take the timed exam. Attend your Discussion section every week. Discussion sections will begin meeting the week of February 3. You are expected to work through the homework problems before your discussion meeting, so you can effectively discuss these problems with your classmates and the TA. After you take an hour exam, it will be handed back and the solutions will be given during your discussion section.
