MA 222 C & D Differential Equations and Matrix Algebra II Winter, 1999-2000 7th and 8th Periods Crapo Hall, G-310 Instructor: R. G. Lautzenheiser Office: Crapo Hall, G-309 Telephone: ext 8394 Office Hours: Posted on my door Email: roger.lautzenheiser@rose-hulman.edu Your numerical grade will be determined by the different parts of the course listed below. Your letter grade will then be based on a scale very close to the 90-80-70-60 scale. Plus (+) grades are often given as a reward for doing better on the final than your numerical score would indicate (e.g. your numerical score is 73 but your final exam score was 85% - probably your letter grade would be C+). I. Daily Homework (5 %). The homework will be posted on our class web page (from my personal web page, click on courses and then MA222 for the winter of 1999-2000). For the most part, the homework will not be graded. I will simply keep track of the number of homework problems that you turn in. Occasionally, I will ask the grader to grade a problem or two. Your numerical score for this part will be MIN{(H/(0.90*Total))*5,5}, where H is your homework grade and Total is the total number of homework points. The homework is due at the beginning of the class period; use 8 ½ x 11 paper (color does not matter) and put your name, mailbox #, and assignment # in the upper right hand corner. Absolutely no late homework will be accepted!! Don’t even ask!!! II. Quizzes (20%). These will be graded. They may be short or long, with Maple or without Maple, announced or unannounced, in-class or takehome, individual or group. Indeed, there may be short quizzes over the assigned reading. Your numerical score for this part will be MIN{(Q/(0.95*Total))*20,20}, where Q is your total quiz score and Total is the total number of quiz points. There will be no make-up quizzes. If you have a legitimate excuse for missing a quiz, I will give you the percentage that you get on the final exam as the makeup score. III. In class exams. Each will count 25%. Exam 1 will probably be given during the 5th week and Exam 2 during the 9th week. I do not give make-up exams. If you have a legitimate excuse for missing an exam, I will give you the percentage that you get on the final exam as the makeup score. IV. Final Exam (25%). PLEASE NOTE I have no control over when the final exam is given. If you have a conflict and I need to change the date of the MA222 exam for a particular individual, the new date will be AFTER the scheduled date of the exam for MA222. I do not accept any late homework. It is due at the beginning of class. Note that I will use 90% of the total number of homework problems to determine your homework grade, so you can miss a few and there will be no penalty. I do NOT give makeup quizzes or exams!!!! If you have a legitimate excuse for missing a quiz or exam, I will give you the percentage that you get on the final exam as the makeup score. Classroom Rules 1) Everyone should be respectful of everyone else. 2) Attendance: I expect you to be in class (and not late). Please see Rose’s policy on absences. 3) Please do not annoy me or others during the class period – e.g. reading the thorn, finishing a paper for another class, talking continuously etc etc 4) Use of the laptop must be related to this class (e.g. working on the worksheet of the day or a quiz…). Each violation of this policy (e.g. playing games, listening to music, using the network, updating your operating system or…) will result in an automatic loss of one letter grade for the course. I will also send a letter to your academic advisor and the dean. I simply do not put up with anyone using the computer when an explanation is taking place or when someone is answering a question. 5) Unless I give you permission, you are not allowed to connect your laptop to the network. Most of the Maple documents that we will be using are in a directory which you should download to your hard drive. 6) In fact, there will be days when we do not use the computer. This information will be on our web page. 7) Always willing to add more…..
