lOOpoint exams administered over the course of the semester and one lBOpoint comprehensive final exam See the attached schedule for the dates of these exams Although the course schedule is labeled tentative the dates for the exams will not change In order for you to have more time to complete your duringsemester exams they will be administered on Wednesday evenings from 705pm S35pm the exact rooms are TBA You must arrange your schedule such that it does not conflict with the evening exams If you have a Universitysanctioned extracurricular activity that conflicts with an exam you must provide written documentation of this to your section instructor at least two weeks in advance of the exam date to be eligible for an early examination Note that all make up exams are to be taken in advance We will not allow any make up exams after the regularly scheduled exam has been given EVEN FOR UNIVERSITYSANCTIONED ACTIVITIES Each student may use his or her percentage score on the final exam to replace either one unit exam grade OR the ALEKS score NOT BOTH This will be done automatically at the end of the semester for any student who performs better on the final exam than they did on the lower of either their lowest unit exam score or on ALEKS again not both The final exam worth 150 points is scheduled for May IO from 200pm to 400pm for all sections The final exam will be cumulative with an emphasis on the material covered since the 4m exam It is required for all students and must be taken during the University scheduled day and time There will be no makeups for the final exam and no one will be able to take the final exam early Please make travelvacation plans accordingly You must bring a pencil your TlSOXa calculator with cover removed and your photo ID to the exam No other materials will be allowed at your desk during an exam Hats books backpacks sunglasses etc must be left in the side aisles of the exam room better yet don t bring anything with you The Chemistry Department andor Colorado State University is not responsible for any personal items lost or stolen during exams Sharing of calculators during exams is not permitted No student may start the exam more than SO minutes late and all students will be expected to remain in the exam room until at least 35 minutes after the exam start time Flacitation The recitation period will be used for problemsolving activities relating to the topics that we discuss in lecture At the end of each period you will be required to turn in work that will be graded Each recitation activity will be worth 0 points and you must be in your section of recitation in order to complete and hand in the work The recitation activity may require you to participate in classroom discussion or to present your work in front of the class All work is due at the end of your recitation period No late work will be accepted and no makeups will be given There will be l l weeks during which recitation work will be collected and graded Your 0 highest grades will be counted for a total of 00 points During exam weeks CHElVl l l l teaching assistants will hold review sessions during recitation times All CHEM l l l recitation sections are open to all students during exam weeks Check the course schedule on FlamWeb for the days and times of the recitation sections Attendance at recitation during review weeks is optional ALES Unline Homework System Each week new goals will be posted on ALEKS for you to work on You may work on your ALEKS goals at any time during the available period At the end of the available period you will be graded based the percentage of your weekly goals that you are able to meet There are IS objectives to complete You will take an assessment at the end of completing most objectives and your highest assessment score in the course of the semster will be used as an additional objective score There will be a total of l4 objectives scores counted this way At the end of the semester your top I l objective percentages will be averaged and converted into a point value out of 00 points In other words your lowest 3 scores will be dropped There are no makeup assignments for completing ALEKS goals by the weekly deadline If you chose to not use the ALEKS system then you may use your percentage on the final exam to fill in for this score but then you will not have the option of a low exam score replacement i CI39oker Flesponse System iClicker is a type of audience response system that helps facilitate interactivity in large classes You must purchase your own iClicker remote that will allow your answers to be electronically recorded during class At the end of the semester each student that has earned at least 75 of the i Clicker points will receive 50 points toward his or her final grade Each student that earns fewer than 75 of the points will receive a corresponding proportion of the 50 points iClicker points will be assigned every day in lecture and recitation except for optional recitation days and you are responsible for bringing your remote daily There are no makeup assignments for iClicker points You must be present in class and use your iClicker to earn them Entering an iClicker response for another student will be considered an act of academic dishonesty Thus if you are caught entering an iClicker response for another student the minimum penalty applied will be for both you and the person for whom you are entering responses will receive a zero for the iClicker portion of your course grades You must register your iClicker in order for your clicks to be counted and graded To do so go to wwwicickercolostateedu and follow the link for student registration Final Course Grade Your final grade will be based on the total number of points that you accumulate on recitation activities homework assignments clickers and exams over the course of the semester You should try to achieve the maximum number of points on all of these activities to contribute to your final grade Letter grade minimums will be assigned according to a standard 0point scale 90 A 80 B 70 C 80 D lt80 F No extra credit or additional assignments will be given Your final grade will be based on a maximum of 800 total course points distributed as follows x 00 points for four hourly exams 400 points 0 x l 0 points for recitation worksheets 00 points 00 points for ALEKS assignments 00 points 50 points for iClicker 50 points I x 50 points for the final exam 50 points Total possible points 800 points Academic Dishonesty The integrity of society and therefore of Colorado State University depends critically on the academic integrity of all of its members students faculty and staff As published in the University General Catalog examples of academic dishonesty include but are not limited to cheating in the classroom plagiarism unauthorized possession or disposition of academic materials falsification and facilitation of cases of academic dishonesty ie helping someone else cheat If you are found guilty of cheating or other academic dishonesty on an exam or on any other assignment the minimum penalty will be a zero on that assignment with no possibility of replacing or dropping that zero The Office of Conflict Resolution and Student Conduct Services will be automatically notified of any inappropriate behavior and anytime a reduced grade penalty is applied Many cases of academic dishonesty arise When a student fall behind in his or her coursework and attempts cheating as a poorly thoughtout replacement for hard work My best advice to you is39 don t fall behind and you won t be tempted to cheat Discussions on FiAMCT The Discussion Board feature for our FlamCT site will be engaged so long as the discussion focuses on science class material and helping each other learn It is not a place to post your gripes vent about the class or to attack another student s post etc Civil intelligent courteous and helpful online behavior is expected of everyone using the board If you have issues with the class us or anything else regarding CHEM l l l please bring them to our attention Our desire is to resolve any issues that you have in a mutually satisfactory way If not we will direct you to the other University resources that you have for resolving conflicts The Golden Rule applies here treat others as you would like to be treated Other Stuff Our vieW on homeworksuggested problems and studying You will be more successful in this class if you practice and work towards understanding many many problems on your own We are available during office hours to help you with any questions that you have but a student who makes a serious effort to understand and solve problems on his or her own without looking in the back of the book or asking someone to give him or her answers will be more successful on exams than a student that does not This will require that you spend a significant amount of time outside of class working on problems reading and testing yourself on concepts that we are discussing There is always value in doing extra problems for extra practice Understanding the concepts behind the topics and problems we discuss is the only way to be successful in this course The quantity of material that is covered in this class is large Since we will be moving quickly through topics it is essential that you keep up with the material When you come across a topic that you do not understand do not wait to get help or ignore that you have a problem Often if you wait too long you will fall behind It is your responsibility to keep on top of your progress in this class by reading answering questions and testing your understanding of the material Simply coming to lectures will not be enough Experience has shown that the students that devote 23 hours or more on quality study outside of class for every hour spent in class will be more successful than the students that do not spend this time That means 812 hours per week studying for this class alonell Of ce Hours We have each set aside 3 hours per week to meet with CHElVl l l l students outside of class see times listed above for each instructor Please take advantage of this time do not think of it as scary and it is not a punishment We want you to come for many reasons three of which are We hate sitting there by ourselves 2 it is the only way we can get to know students in such a large class and 3 we see it as an opportunity to offer you free tutoring Feel free to bring book problems to work on or plan on meeting a study group at this time Additionally Yates 412 has computers available for you to work on your weekly ALEKS assignments Tutoring The College of Natural Sciences Science 3 Mathematics Tutorial Hall offers free tutoring for CHElVl l l Information can be found at wwwnatscicolostateedututoring Please turn off all cell phones before entering class Really If you use your laptop to take notes please use it only for taking notes Please do not use your laptop for watching movies surfing the internet or playing video games since this can disrupt your classmates Additionally if you do decide to engage in anything not related to class during lecture do not come to our office hours and ask us how you can do better on exams The answer will be obvious Tentative Schedule of Topics REVIEW SHEET FINAL THE FINAL IS MANDATORY The nal is worth 150 points and will be about 40 questions in length There will be about 16 questions on previously covered material approximately 4 per exam There will be about 24 questions on the material covered after exam 4 Do not expect all the questions on previously covered material to be identical to those on the final although we ll give you one from each previous exam The concepts to review both old and new are listed below You have 2 hours to take the exam Please give special attention to the following subjects and review previous exams in the context of the subjects below at least for those that you ve been tested on before You may NOT take the final exam with you when you leave the room If you wish to see the final exam later on you may do so by appointment You may begin the final exam at any time during the testing period and you may leave at any time prior to the end of the 2 hour exam period but you must be done by the end of the designated exam period
