Course Content For the purpose of quizzes, the course content is defined by (a) the lectures, (b) the relevant chapters and problems in the text, (c) lecture problems, and (d) problem sets. The outline and order of the topics covered is presented at the end of this handout. Please note that not all chapters will be covered in the order they are in the book. Some sections have been omitted. The sections that have been indicated as excluded will not be covered in the lectures, and the material will not be a part of the tests. It is recommended that the excluded sections be studied independently by students in pre-medicine, chemistry, or related programs. Grades Your course grade is based on the scores of 17 lecture problems (5 points each; 85 points total; 23% of final grade), four problem sets (20 points each; 80 points total; 22% of final grade) and four quizzes (50 points each; 200 points total; 55% of final grade). Final grades will most likely be based on a curve. After each quiz, you will receive some feedback as to how your numerical scores might translate into letter grades. These indications should be treated as rough estimates of your final grade. The average in the class corresponds to C+/B– grade. Lecture Problems (23% of Final Grade) You are required to complete 17 lecture problems, which will be handed out the day before their due dates. Each lecture problem is worth 5 points. The lecture problems may be taken from the textbook, an MCAT sample exam, or created by the instructor. These problems will serve as good practice in understanding the course material, preparing you for quizzes, and keeping you up-to-date with the lecture material. The lecture problems are to be handed in at the beginning of lecture; their due dates are listed on the course schedule. Problem Sets (22% of Final Grade) You are required to complete four (4) problem sets, which will be handed out during class about one week before they are due. Each problem set is worth 20 points. The problems from these sets will resemble the kinds of problems that will be on the quizzes. The problem sets are to be handed in at the beginning of lecture; the due dates for the problem sets are listed below and are also listed on the course schedule: Problem Set 1: Friday, June 23 Problem Set 2: Thursday, July 6 Problem Set 3: Thursday, July 20 Problem Set 4: Thursday, August 3 Quizzes (55% of Final Grade) All quizzes will be offered during the class time (8:00 – 9:15 am) in 117 Osmond. The quizzes will mainly include short-answer questions. They will be constructed in such a way as to emphasize active understanding of the material. Each quiz is worth 50 points. To take the quiz you will need pencils and your student I.D. card. You cannot use books, notes, calculators, etc. You may, however, use a molecular model kit, providing it does not contain any written materials. Practice questions in the form of old exams are provided on the course website. Questions on your quizzes will be similar in style and level of difficulty to those offered on the course website. The quiz schedule is listed below and is on the course schedule: Quiz 1: Monday, June 26th Quiz 2: Friday, July 7th Quiz 3: Friday, July 21st Quiz 4: Friday, Aug 4th Procedures One comprehensive make-up quiz will be provided near the end of the semester to students with valid excuses (family emergency, illness, etc.) who have missed either of the first three quizzes. In order to be permitted to take the make-up quiz, you must provide the instructor with a documented, written explanation of your absence within one (1) week of the make-up quiz date (TBA). This explanation must include a telephone number for a person who can corroborate the reasons for the absence, but should not include any unnecessary private details. All students permitted to take this quiz must sign up with the instructor one week before the quiz. Late-drop students will receive WN designations on their transcripts. Students who have taken at least two quizzes may request a WP designation, if their class average is higher than the final grade line for a C. Requests for WP designation must be submitted in writing no later than the last day of 2 class. General Considerations: Chemistry 39 is a continuation of Chemistry 38 and, as such, builds on the foundations introduced in the first semester. If you did well in Chem 38, then you should be well prepared for Chem 39. If you were below average, then the second semester may be somewhat difficult for the problems are more mechanistic and a greater emphasis is placed on the synthetic aspects of organic chemistry. Owing to the hierarchical nature of the material, it is important to not fall behind or leave studying for the exams until the last few days. The material is not inherently difficult, but you must understand some concepts before you can go on to new ones. Therefore, be sure to allow yourself sufficient time for absorbing the material. Observations made over the past few years suggest some generally useful strategies that help to improve student performance. These are summarized below. Read the chapter material before the lecture Study everyday, do reviews bi-weekly Solve as many end-of-chapter problems as possible (resort to answer book only after you have attempted the problem) Study with a friend; if you can explain a concept to your study mate, you understand it Just reading and understanding the material (passive understanding) is insufficient; you should be able to use the just learned concepts in situations not previously encountered, and make logical connections with concepts learned previously (active understanding) Constantly probe your understanding by asking (and answering) question "why?" in relation to all statements and logical constructions Do not fall behind in your study; especially when there is new material every day; it is virtually impossible to prepare well for the quiz in just a couple of days before it Academic Integrity: Instructors are now asked (Senate Rule 49-20) to provide at the beginning of a course a statement to "clarify the application of academic integrity criteria to that course". The Senate Rule includes the following: Academic dishonesty includes, but is not limited to, cheating, plagiarizing, fabrication of information or citations, facilitating acts of academic dishonesty by others, having unauthorized possession of examinations, submitting work of another person or work previously used without informing the instructor, or tampering with the academic work of other students. (You should also be aware of the extensive parts of this Rule that describe procedures for handling alleged instances of academic dishonesty.) Specific instances of academic dishonesty in this course would include (but not limited to) copying or helping someone else copy during an examination, using unauthorized materials during an examination, stealing or destroying course materials or another student's examination paper, altering answers or grades on graded examinations, having someone take an examination for you, and attempting to do any of the above. Such infractions are considered cause, at the least, for awarding a grade of "0" on the exam in question (and not allowing the student to drop the class). 3 Chemistry 39: Outline of Lectures 1.
