Term Paper: The term paper is a major part of the course that is designed to familiarize you with some area of current research in analytical chemistry. You will pick the topic from the current chemistry literature (within about 5 years of the present), have the subject approved by me and then write an approximately 10-page paper on the subject with at least five references from the chemical literature (no internet addresses). The topic of the paper may not be identical to that of one of the lectures, the references may not be identical to any one of those reviewed in the course, and if you want to discuss at topic similar to your research, please consult me. The term paper should focus on a particular problem (e.g. detecting genetic mutations) or analytical method (e.g. ICR-MS), or both (e.g. detecting genetic mutations with ICR-MS). I suspect that the latter approach will often be the best because it places limits on the scope of the topic. The information from several sources should be integrated and the paper should ideally reflect an understanding of various issues or perspectives relative to the subject that you are studying. Almost always there is a way to summarize the overall issue that reflects a good level of understanding of the subject matter. Undergraduate, textbook-level review of the basic principles may be a good way to introduce some of the experimental methods. (1) Read the article. (2) Understand as much as you can. (3) Write about what you understand in as much depth as you can and (4) don’t try to do go beyond what you understand. I enjoy hearing about what you know, but stretching this to try to sound smart is obvious and ill-advised. Write in a formal tone, but don’t try to impress me. When in doubt – just report the facts. Unfortunately, I do need to remind some that the report must be original writing – please do not to copy directly from the articles (plagiarize). Even if you properly cite the sentence or paragraph, it must be in your own words. A very limited number of direct quotes are allowable. The University defines plagiarism as “The act of incorporating the ideas, words, sentences, paragraphs, or parts thereof, or the specific substance of another's work, without giving appropriate credit, and representing the product as one's own work;” The university recommends that “violations of … this policy the recommended sanction shall be 3.1.2, failure in the evaluation instrument or 3.1.4, failure in the course”. OUCH! Oral presentation: During the last few weeks of the semester, we will schedule short (ca. 15 min) presentations of the paper topics that you discuss. The recommended format will be overhead transparency – other accommodations will require advanced notice. These presentations will be worth 25 points. Due Dates and Policy on Late Work: I all material are submitted via Canvas, so submission after the due date will not be possible except in extenuating circumstances and by agreement with me. Exercises will typically be due before the beginning of the next activity period. Drop Policy: The deadline to drop classes without a W is Tuesday, September 6th. The deadline to add is Tuesday, September 13th. After the regular drop period ends, only documented medical or similar emergencies will be accepted as a valid reason to drop a course. Note particularly that a change in work schedule is no longer an acceptable reason. Therefore, it is critical that you inform your employer that you have a serious commitment for your scheduled class and laboratory times during the whole semester. If your employer cannot guarantee that you can meet this obligation, then you should drop the class in order to allow someone who can fulfill this commitment to register. Also, be aware of the fact that “unsatisfactory performance in
Page 4 of 5
course work and protection of your GPA is not a serious and compelling reason in itself for requesting permission to drop”. After the twentieth day of instruction, all petitions to drop classes or withdraw from school will be reviewed by the Director of Academic Services. Petitions are available in the Student Resource Center.
ADDENDUM TO ALL CHEMISTRY DEPARTMENT GREENSHEETS (Except Chem 291 Sections)
Revised August 2016
University Policy Per University Policy S16-9, university-wide policy information relevant to all courses, such as academic integrity, accommodations, etc. will be available on the Office of Graduate and Undergraduate Programs’ Syllabus Information Web Page at http://www.sjsu.edu/gup/syllabusinfo/ CHEMICAL SAFETY – all courses
Chem 120S is a required course for all chemistry majors and minors and a prerequisite for all Chem 180/298 research.
EMERGENCIES AND EVACUATIONS – all courses
If you hear a continuously sounding alarm, or are told to evacuate by Emergency Coordinators (colored badge identification), walk quickly to the nearest stairway (end of each hall). Take your personal belongings, as you may not be allowed to immediately return. Follow instructions of Emergency Coordinators. Be quiet so you can hear. Once outside, move away from the building. Do no return to the building unless the Police or Emergency Coordinators announce that you may.
DISABLED STUDENTS – all courses
Campus policy in compliance with the Americans with Disabilities Act: "If you need course adaptations or accommodations because of a disability, or if you need special arrangements in case the building must be evacuated, please make an appointment with me as soon as possible, or see me during office hours. Presidential Directive 97-03 requires that students with disabilities requesting accommodations must register with DRC to establish a record of their disability."

ACADEMIC INTEGRITY STATEMENT – all courses (from the Office of Student Conduct and Ethical Development):
"Your own commitment to learning, as evidenced by your enrollment at San José State University, and the University's Academic Integrity Policy requires you to be honest in all your academic course work. Faculty members are required to report all infractions to the Office of Student Conduct and Ethical Development. The policy on academic integrity can be found at http://sa.sjsu.edu/student_conduct.
LABORATORY SAFETY – all laboratory courses
You should read the safety section of the SJSU Catalog under Chemistry Department (page 121 in the 2006/08 Catalog). Note in particular: “Failure to comply with proper procedures and prescribed safety cautions shall subject the student to disciplinary action. 1) Any student who engages in unauthorized experimentation, or who seriously disregards safety, thereby endangering self or others shall be withdrawn immediately from the class with a grade of F. 2) Any student who shows persistent disregard for safety may have his/her grade lowered, and may risk being withdrawn with a final grade of F.”
