Syllabus for Chem110.002 Summer 2008 Lecture Instructor: Liina Ladon Office: Chemistry Tutoring Center, SM538 Office Hours: By appointment Phone: 410-704-3054 E-mail: lladon@towson.edu Lecture/Lab: MTWRF 8:00am – 11:50pm Lecture meets in SM506 on MTR and SM524 on WF Lab meets in SM507 Web page: www.towson.edu/~ladon Blackboard site log-in: http://learnonline.towson.edu/ Required Materials: Lecture Textbook: General Chemistry, Raymond Chang, 5th Ed., McGraw Hill, Boston, 2005, Text ISBN 978-0-07-304851-2 Lab Textbook: Laboratory Experiments In General Chemistry: CHEM110 and CHEM111, Version 8.0, 2005, Towson University. This is an “in-house” manual. Laboratory Goggles: Must be ANSI approved and cover the eyes completely. The chemistry club sells two varieties ($10.00). They are cheaper and more comfortable than the goggles sold at the university bookstore. Additionally, there are a limited number of used pairs for $5.00, but they sell out quickly. The used pairs have been sanitized. Laboratory Notebook: Must have carbon copy pages that can be turned in as a duplicate of what has been recorded in the notebook. These are also sold by the chemistry club ($11.00), and at a price that is cheaper than the bookstore. Calculator: Calculator: A scientific calculator is recommended for the course. The calculator should be able to display scientific notation, be able to take roots of numbers, raise numbers to any power, take logarithms and antilogarithms in base 10 and base e. I will not allow programmable calculators for this course due to increasing incidence of students storing illegal information in the memory of TI83 type calculators. I suggest a calculator, such as the TI36X, which is solar (no batteries needed) and simpler to operate than the TI83. Note: Palm pilots and cell phones may not be used for exams! Attendance: Prompt attendance is strongly recommended. If you are late or miss a lecture, it is your responsibility to acquire information given out during lecture. Make-up exams will not be given. In the event an exam is missed, you must bring valid documentation (obit, garage receipt, doctor’s note, etc.) Pending approval by the instructor, the final exam will be weighted an additional 13.3 % to cover points missed. Over-sleeping, for instance, is not a valid excuse. Invalid absences from an exam will result in a grade of 0 for that exam. Only one make-up exam per student per semester! If you are more than 20 minutes late for a lab, you will not be able to perform the experiment and will receive a grade of 0 for that lab. Please turn off cell phones and beepers while in class out of consideration for your classmates. It can be very distracting – especially during an exam! In addition, class time is not a social hour. Please refrain from casual conversation during class time. You will be asked to leave the classroom if you disrupt the class. 1 Blackboard website: I will be trying out the use of Blackboard, an online information hub for coursework. Please be patient! I confess I am a Blackboard “amateur”. I hope to post useful information, the challenge problems, old exams and have a chance for you use the discussion board for help from your classmates and me on course material. Any suggestions from those of you who have used Blackboard in the past are welcome! To access Blackboard, you need to create an account for this course. To do so, launch your browser and open http://learnonline.towson.edu. Click Create Account, follow the instructions on the screen and fill in the form accordingly. The username must be lower case. If you have trouble, please see me and I’ll see what I can do to help you. Once you have logged into the LearnOnline, click the Courses tab and locate this course using either the course ID or my name. Next, click Enroll and then Submit. ARIS website: The textbook has a useful website: http://www.aris.mhhe.com which is a great resource of supplemental material. You do not need to sign in or register for the site and it is free of charge. In particular are many animations (for you “visual learners”) and self-assessment quizzes. Choose “chemistry” as the subject, Chang, 5th ed. as the textbook. When the textbook section appears, choose the Resource tab at the upper left corner of the tool bar and go nuts! You do not login with a username or password. Pick a chapter and see what you find! Lab Reports: Lab reports will be due at the beginning of the performance of the next experiment. Any reports handed in after the due date will be considered late, and a grade penalty will be assessed. The grade penalty is a reduction of one letter grade for each day the report is late. Lab reports will be graded based on completeness (all parts of the report are included), accuracy of the calculations (where appropriate), accuracy of answers to post lab questions, and accuracy of results (where appropriate. If the report is incomplete or has calculation errors, points will be deducted accordingly, so it is to your benefit to check your report carefully for completeness and check your calculations for accuracy before submitting the report. If you do not attend lab and do not turn in a report, a grade of 0% is given. If you attend a lab, but do not turn in a report, a grade of 50% is given. A complete report that is turned in will receive a minimum grade of 70%. Please feel free to seek help in the tutoring center, should you need help with your reports. Reports should be prepared using a word processor. Graphs should be prepared using Excel. Other graphing programs may be used, but please show a sample graph to your lab instructor for his/her approval. If you are submitting a report via e-mail, please make sure it is in Microsoft Word format. If I cannot open the attachment, or the attachment is unreadable, I cannot count it as a report. You will be working with a lab partner. Please make sure that your lab report is not identical to your partner’s. This carries the penalty of plagiarism. Grading: 3 lecture exams 11 laboratory experiments 1 final exam (cumulative) 40 % 25 % 35 % Your course grade will be based on the percentage of points earned. As you can see, a good course 2 grade is achieved by performance in all aspects of the course. Don’t count on any one section of the course to either pass or fail you. The final exam is cumulative for good reason. The material you will have learned in Chem110 is essential background material for Chem111 and beyond. Course grades will be assigned as follows: 93 –100 90 – 92.9... 87 – 89.9… 83 – 86.9… 80 – 82.9… A AB+ B B- 77 – 79.9… 73 – 76.9… 70 – 72.9… 67 – 69.9… 60 – 66.9… C+ C CD+ D <60 F Your course grade is calculated as a weighted average: Final course grade = 0.4(lecture exam average) + 0.25(lab average) + 0.35(final exam grade) Also, you must pass both lab and lecture in order to pass the course. This is a departmental policy. In over 20 years of teaching, I have never had to curve grades. Cheating I “take no prisoners” when it comes to people cheating on exams. If you want to guarantee yourself an F in the course, then cheat on the exam. All incidences of cheating will be reported to the University Academic Standards Committee, and you will risk dismissal from the university and have a notation of academic dishonesty placed on you permanent school record. It would thus seem that flunking an exam, if unprepared, would be preferable. Additionally, a lab report must not be identical to that of another classmate. Tutoring Since I am in charge of the tutoring for the sciences—please feel free to seek me out in the tutoring center. Tutoring is available, free of charge at the Chemistry Tutoring Center located in SM538. No appointment is needed to access the service. I have other duties to attend to at times, such as meetings, so I may not always be there when scheduled. When this happens, I will try to post a sign in advance, and/or let you know during lecture. In the summer, it’s best to call ahead and make sure I am available to help. I encourage you to avail yourselves to this service—many students do well in chemistry courses with help from the tutoring center. Also available as a resource is the tutoring center’s home page: http://www.towson.edu/~ladon. There are well over 150 pages of study aids there for your use. General Advice 1) Don’t procrastinate—a lab report isn’t going to magically appear on your monitor in the 45 minutes before it is due, nor is 3 weeks worth of lecture material going to download into your brain in 3 hours before the exam. 2) Work as many problems from the textbook as you can. If you can only correctly answer 50% of the problems, then you have a good idea of your potential test score—GET HELP! 3) Let the information build—the subject gets easier, not harder, if you do this. There are only 24 hours to a day. If you have to relearn what you forget, at some point there won’t be enough time to do all the work needed to review the old material and learn the new material. Do 3 whatever it takes you to put information into long-term memory. (Association, repetition, reinforcement—using flashcards you can make, working problems, thinking about the concept, talking or explaining the concept to someone else, rewriting notes, mnemonic devices.) 4) When taking an exam, all you can ask of yourself is the best you can do—so don’t stress.
