CH 302--Random Musings, Bottom of the Ninth for Spring 2010 1. Sadly, the semester has come to an end. I have actually come to know so many of your faces, if not your names, and will remember those faces kindly. This is the class where I tried out calculator free exams and you stepped up and took it on without complaint. Thank you for that--and to top it off, the class still had the highest average of any class I have every had to date. Good for you. Today in class I will briefly cover the material from catalysts and batteries, review things to think about for the exam tonight, hand out your very own brass penny, and review issues related to examinations and final grades, and then set off the first ever quadruple thunderstorm. 2. Evaluations. It is your responsibility as a student to complete course instructor evaluations for every course you take. You should have received an electronic invitation to complete this survey, but if you haven’t, you can do so by going to the following web link: https://utdirect.utexas.edu/diia/ecis/ and opening up the survey for CH302 unique number 52455. You have until 5/7/2007 (this Friday) to complete the survey. Thanks for remembering to do this. 3. I have the good fortune of being able to handpick my TAs, and I do a pretty great job of it. Mostly being freshmen, you will not have the experience yet to know that this is about as good as it gets. I can’t thank them enough for their efforts—you will be lucky to see something like this again from TAs at UT. 4. Reprinted below are the grading cutoffs for the course. There are both the original cutoffs and the new cutoffs that apply IF you turn in all your extra credits. The weight of the extra credit depends on the grading scheme but corresponds to 1% of the grade for each extra credit handed in. Do not worry about which of these grading schemes applies to you. I will assign the one that best benefits you. Grading: The Cutoffs 5. Here is a master scoring table for people who don’t like calculating percentages. Listed below are the current cutoffs for grades in this class done for each of the grading schemes. Note that there are three ways to earn your grades, and depending on whether you did the extra credit, two sets of cutoffs for those three grading schemes. These are the number you should be evaluating as you stare at your Quest test and quiz scores. Don’t use Quest’s idea of a grade. It is not based on my grading schemes. no extra credit submitted three extra credit submitted—3% reduction course grade exemption (700 points) cumulative (1000 points) final (300 points) exemption (700 points) cumulative (1000 points) final (300 points) A 651 930 279 630 900 270 A- 630 900 270 609 870 261 B+ 870 261 830 249 B 830 249 800 240 B- 800 240 770 231 C+ 770 231 730 219 C 730 219 700 210 C- 700 210 670 201 D <700 <210 <670 <201 F <600 <180 <570 <1716. Extra credit points. You have had the chance to 3% back on your grade from extra credit. There will certainly be some errors in recording your extra credit what with the manual recording process so please do not panic if points are missing. I will reconcile what I have for your totals versus what you say you have done the green sheet you will turn in today. If there is a contradiction, I will e-mail you to confirm. I need these extra credits to determine exemption, so please get them in by Saturday at 3 am. 7. If you are missing Quest scores or believe that they are in error, it is your job to contact Travis at once. Travis will send me the information to post about how to get errors remedied and it is up to you to follow through. We really want to make it possible to assign exemption cutoffs accurately and as soon as possible. So please get on this. 8. By Saturday around 8 am I will have determined whether the exemption cutoffs will vary from the cutoffs posted above. Remember that the Quest totals DO NOT reflect my grading scheme so ignore the grades it assigns and instead simply add up your three exams and your four best quizzes, then compare it to the column based on whether you did the extra credits. 9. You have been a very fine class and the grades will reflect this. Expect to see about 150 exemptions and the final overall grade distribution: 200 As 170 Bs 90 Cs 30 Ds 10 Fs (most of whom did not complete the course). 10. Telling me what I should know. In a class of 500, it is possible I will make mistakes or that I will not find out things you want me to know. So please fill out the green form, “Things I want Dr. Laude to know”, if there is anything of an academic or non academic nature that will assist me in deciding your grade. I will respond to each of these individual so take the opportunity seriously. For example, if you and I have made some kind of arrangement about make-ups, missing quizzes, incompletes, or something significant has come up this semester, please write it down and turn it in. 11. A request for EVERYONE about final grades: I took great pains to devise a thorough grading scheme for this course. It is clearly identified in the syllabus. Read it before you start asking redundant questions. It is what it is. Be aware that I will not do for a single student what I wouldn’t do for everyone, so please do not expect special favors. Things you need to know about Exam 3. 12. Travis and I have provided practice exam 3s that I have posted on the web. 13. On Monday I gave a review on the 35 question types on Exam 3 and the hand written notes from that session are posted on line. 14. Exam 3 will be given tonight from 7:30 till 9:30. The exam will consist of 35 equally weighted questions worth a total of 210 points. The list of question types has been posted twice in previous musings. 15. I am forgoing a posting of the normal format and procedures for exam 3 and remind you that the usual exam rules apply. Your location for the exam is as follows: Last name A-K, WEL 2.224. Last name L-Z, BUR10616. There will be a make-up exam on Sunday night in Welch 2.224 from 7 until 9 pm. I have relaxed the conditions for taking this makeup, so take it if you want, and don’t e-mail to let me know—just know that if you show up for tonight’s exam, you will have to take it. Also, later this evening I will post with my lecture notes a collection of revised hints for the main group chemistry so that the
