COURSE OBJECTIVES: The student will learn more about the basic concepts, laws, and theories of some of the topics discussed in General Chemistry and will be able to apply the knowledge to chemistry problem solving at an advanced level. The student will develop an appreciation for chemistry as it relates to the other disciplines. Furthermore, the student will earn how chemistry provides solutions to contemporary, historical, technological, and societal issues. ATTENDANCE POLICY: Attendance of class is mandatory. A student with four or more excused absences will result in an "F" for the course. Moreover, coming to class on time is required. A tardy counts as ½ of a absences. Thus, 8 tardies will result in an F for the course. ACADEMIC HONESTY POLICY: Any student found cheating will be subject to the penalties as stated in the Student Code of Conduct handbook; including but not limited to a score of zero on exam, expulsion from the class or expulsion from the University. Academic misconduct includes plagiarism, copying answers from friends, copying solution manual answers that you claim to be your own. (( 2

3 Examples of academic dishonesty include: Exchanging answers or information during a test or quiz Looking at another student s paper during a test or quiz Bringing or looking at a book or other unauthorized source during the quiz or test If caught cheating a zero will be given to the cheater and or both students colluding in cheating. Other steps will be taken as stated in Students engaging in any type of academic misconduct (including, but not limited to: cheating, plagiarism, or any other action that can improperly affect my evaluation of your performance) will be subject to sanctions in accordance with SFA Academic Integrity Policies. Please note: The usage of electronic devices (including, but not limited to: cell phones, PDAs, mp3 players, etc.) while a quiz or exam is being given will be treated as academic misconduct. DO NOT HAVE THESE DEVICES OUT DURING A QUIZ OR AN EXAM! I will recommend a grade of "F" for the course. SEMESTER WITHDRAWALS: PLEASE CONSULT THE ACADEMIC FOR THE LAST DATE TO WITHDRAW WITHOUT OBTAINING A WP OR WF. ACADEMIC DISABILITIES POLICY: Students with Disabilities To obtain disability related accommodations and/or auxiliary aids, students with disabilities must contact the Office of Disability Services, Human Services Building, Room 325, / (TDD) as early as possible in the semester. Once verified, DS will notify the course instructor and outline the accommodation and/or auxiliary aids to be provided. CLASSROOM BEHAVIOR POLICY: To ensure a classroom environment conducive to learning, any forms of classroom disruptions will not be tolerated (examples but not limited to talking, use of cell phones/beepers, sleeping, reading other material, eating/drinking). Students who violate these rules will be asked to leave. Repeat offenders will be subject to disciplinary action in accordance with University policies as described in the Code of Student Conduct. Note: If you are taking this course in preparation for the TEKS (to become a teacher) you need to contact Dr. John Moore in Math

4 GRADING SCHEME: Grades are based upon performance. A single grade will be given for the laboratory and the lecture. The table below gives the various categories used for the course/laboratory. Category % Grade Date(s) Exam 1 10 Monday 2/9 4-6:30pm Exam 2 10 Monday 3/2 4-6:30pm Exam 3 10 Tuesday 3/24 8-9:15am Exam 4 10 Monday 4/27 4-6:30pm Final Exam 10 Wednesday 5/ am Pop Quizzes 10 At least 9 quizzes; 1 given during dead week Weekly in class problems 5 Every Thursday by 9:20 scan-tron 882 Sapling 5 Every Friday by midnight Results in the laboratory 15 See next table Lab reports 10 Due 3/13 and 4/30 Lab notebook 5 Checked about once every two weeks. 5 points each check. All of the exams will be comprehensive including concepts from CHE 133 and CHE 134. These exams will consist of problems that must be set up and solved, discussion questions, and/or multiple choice, true/false, math problems, fill-in-blanks or essay type questions. Partial credit will be given for short answer problems worked partially correct; therefore, it is crucial to show your solutions to the problems, not just the answer. Students have one week from the day any graded item is returned to notify professor of grading error or ask questions about the grade of item. After one week no points will be returned. The professor has the prerogative of re-grading the entire item. Multiple choice questions will have no partial credit. Exams 1,2 and 4 will be given in the evening from 4:00 p.m to 6:00 p.m. in MATH 132. Please note, the time overlaps with your required recitation by 50 minutes. If you have a class immediately after the recitation, please contact Dr. Fry as soon as possible so that arrangements can be made for you to take the exam at another time. Exam 3 will be given during class time. Dr. Fry will not be present for the exam; another faculty member or a graduate student will proctor the exam. If the faculty member or the graduate student reports that a student was uncooperative or that they cheated the student will receive a zero on the exam. Moreover, if the student cheated on the exam the student will be reported to the Dean and receive an F for the course. The student assumes responsibility towards making the adjustments in needed to the student s work and/or extracurricular schedule to accommodate for the exams. Please keep in mind that 2 hours are allotted for the exams for a reason. You should expect exams that are thorough and challenging. Plan to stay for the entire two-hour period. Students arriving late will not be given extra time. Students who arrive more than 15 minutes late will not be allowed to take the exam. NO students may leave before 5:00pm. No make-ups will be given for an exam regardless of the reason the exam was missed. Instead, the percentage score from the ACS standardized final will replace the missed exam. Please note, this means that the no curve will be applied to the missed exam. 4

5 The final exam will be a comprehensive, nationally-standardized exam developed by the American Chemical Society (ACS). The exam consists of multiple-choice questions, and is graded on a scantron (please bring scantron 882E to the final exam with you). The ACS final provides a national ranking for each individual student. Your national ranking will be used to compute your final exam score. The equation used in the past was: final exam score = percentile + (100 percentile) percentile 100. In the past, students who scored in the 50 th percentile made a 75% on the final exam. Those scoring in the 25 th percentile made a 43.75%; those scoring in the 75 th percentile made a 93.75%. More specifics about the final will be given during dead week. Again, please note, those students who missed an exam will not receive this curve; instead they will have the percentage correct as the exam that they missed. Since the exam in a standardized national exam, there will be material that was not presented in class on the exam. Students should start worrying about the final exam the first day of the class; not at the end of the semester. Moreover, they should turn their worrying into study time. The final exam must be taken; students not taking the final will receive a grade of F (or qf if appropriate) regardless of the percentage total. Periodic Pop-Quizzes will be given in laboratory, lecture and/or recitation. No make-ups (regardless of the reason) will be given for missed quizzes. Instead, the lowest few quizzes will be dropped. When the quizzes are given at the beginning of the class or laboratory period, tardy students will not be allowed to take the quiz! Bring your calculator to class, laboratory and recitation in order to use it on the quizzes. Electronic homework from Sapling Learning will be used weekly. No make-ups will be given for these assessments; instead the lowest few will be dropped. The electronic homework is due Friday at 5:00pm of each week. Students who do not score at least 50% in this category will receive an F for the course regardless of the percentage they have in the course/laboratory overall. Lab Results matter. This is the course where you have the opportunity to improve your lab skills! Take advantage of this. The table below describes how the 15% of the course/laboratory grade in the lab results category are distributed.
