But you really don’t need to buy it. You are welcome to come to my office and check your answers using my copy if you must. The first three ChemActivity Exercises answers will be up on Blackboard 2 days after we finish the activity. Doing Organic Chemistry: Imagine a coach who spends the entire lesson demonstrating good techniques but never lets her students try out their new skills on the court. Would you want that person for your coach? We learn by doing. This class is about doing organic chemistry yourself. We will be working on problems each day in class. If you don’t get something right the first time, your classmates and I will be right there to critique your form and help fix what’s going wrong. Research has found that, at its best, organic chemistry is a team sport, so you will be working in groups of four or five. The better your team works together, the more successful each individual will be. The purpose of a science class is to teach students how to be scientists. So what is a scientist? A scientist is a person who can a) look carefully at a situation that is new to her, b) construct logical conclusions based on observations and c) discuss the merits of her conclusions with peers. C is of particular importance in this era of collaborative research. These days, no one makes a major discovery by him/herself; the abilities to communicate ideas and to work within a team are essential. Class Format: Most class periods will begin with a brief question and answer session based on the previous day’s material. There will then be a ten minute quiz (taken individually) covering the previous day’s material. This is to encourage you to keep up. Remember that if one member of a group falls behind, the progress of the whole group is adversely affected. The quiz is followed by group work on a ChemActivity Worksheet so you must bring your workbook to class every day. During this time, I will walk around the class, observe, ask and answer questions. Groups: The bulk of class time is spent working in groups. I will assign group membership and will reshuffle groups frequently at first so you can get to know everyone. You are strongly encouraged to work outside of class in groups. Find a study partner or start a study group. Studies show most successful students do the bulk of their homework in a productive group environment, and most students who fail are working alone. FIND A STUDY PARTNER! This is the single most important thing you can do to make yourself successful in this course!! During the semester, you will each evaluate the other group members’ as well as your contributions to the group based on the criteria to be handed out. o o You will receive a zero for group performance if you do not submit an evaluation of the students in your group within one week of the request. Your assessment of your peers will be totally confidential. At the end of the semester, you may receive your total performance score, but you will not know who gave you what score. Out-of-class work: You must complete each day’s ChemActivity worksheet by the beginning of the next class period, including the skill development exercises at the end of the activity. It is best to work through the assigned sections in the McMurray textbook after you have completed the ChemActivity. (Assigned reading is found at the end of the syllabus.) ChemActivities will not be collected or graded. There will be selected, special, homework assignments periodically during the semester that should be done individually and will be collected and graded. The problems suggested to be done at the end of the chapters in McMurray should be done, and I encourage you to work on them with your study group. If you hand in copies of all problems done on a regular basis (see in class schedule for due dates), you will receive points. These problems will count for a total of 50 pts in the course total. This course will use Blackboard. Answer keys, sample exams, useful links, and announcements will be posted there. You should check there at least twice a week. Grading Scheme: 3 exams (lowest one will be dropped) final (comprehensive) quizzes (constantly) group work homework end of chapter problems laboratory (50 pt exam) 200 200 200 50 50 50 300 1050 Total The MAXIMUM percentages for a certain grade are listed below. 4.0 3.7 3.3 90 85 80 3.0 2.7 2.3 75 70 65 2.0 1.7 1.3 60 55 50 1.0 45 0.7 40 0.0 <40 Class Policy: Grades will be assigned on the basis of 1050 pts, as outlined above. There will be three hourly exams worth 100 pts each. The best two grades will be used to compute your final grade. Any missed exam, regardless of the reason, will count as the dropped exam grade. Missing more than one exam will result in scores of zero for the missed work. Make-up exams will not be given for missed work. There will be no make-ups for quizzes. If you have a valid excuse (determined by me) to take an exam at another time, you must make arrangements ahead of time or at least by the next day after the exam. The lowest three (or more, at my discretion) quiz grades will be dropped. No late homework will be accepted. Submit only your own work for your own credit. Any instances of suspected cheating in this course will be dealt with according to the current Academic Dishonesty Policy. The Science Center faculty strongly enforce the University’s Policy. You can not be a scientist and not be ethical! Because the laboratory experience is an integral part of this course, concurrent enrollment in lab is required, and a passing grade of 50% in lab is required to pass the course. My view of organic chemistry: Many students view organic chemistry as a cruel hurdle placed in their path to test their tolerance for pain. Consistent with this view, many students’ main goal is to survive the course with a decent grade. I encourage you to expect more from this course for two reasons: I have found that students are more successful at organic chemistry when they enjoy it, so I have worked hard to create a course that students can enjoy if they work hard. Organic chemistry is an opportunity to hone skills like data analysis, problem solving, and working effectively as part of a group. If you invest the time and energy you will learn skills in this course that will make you more effective in your other courses and in whatever career you choose. Organic chemistry is not a hurdle; it is a staircase to a new and powerful way of dealing with the world. That is why, more than any other course, admissions committees and future employers care about your grade in organic chemistry.

I really didn’t want to do group work at first because I have been successful taking notes and studying by myself. But it works. Do not hesitate to talk and meet other students in and out of class. They understand things you don’t, and vice versa. Don’t fall behind. Playing catch up is not fun. Don’t be afraid to ask questions and argue in your group. That is the way learning is done in this class. Learn the reactions and read the textbook (McMurry). You may think (like I did) that group work in organic chemistry is a bad idea. (I thought it would be the blind leading the blind.) But it really does work. I experienced both. I had lecture for Organic 1, and I have really enjoyed the group work in Organic 2. Working together is the most important asset you have. Teaching others is an awesome way to reinforce what you have learned. If you sit passively in your group, you don’t help anyone (especially yourself). Find people you work well with in and out of class. It helped me to find a study partner who I could meet with twice a week outside of class. This format is much more fun and less intimidating than a lecture. You actually learn in class. In my lecture classes it was always about going home and trying to figure it out later. I liked the idea of group work, but was afraid it would not prepare me for the final exam. My advice to future students: Don’t worry. Fall into the format and it will carry you through. Don’t let yourself take the course lightly just because class is fun and relaxed. Do the homework and reading.
