Organic Chemistry I CHEM 351 Winter 2018 Instructor, Course and Lab Coordinator: Dr. Wendy Benoit EEEL 235A wlbenoit@ucalgary.ca Course Overview: Office hours and schedule posted on D2L during first week of classes. If you aren t able to make it to office hours, please contact me by email to setup an appointment. CHEM 351 provides a chance to see the foundation of organic chemistry, through consideration of structural features and how these link to a compound s properties and reactivity in organic reactions. In many ways, the course may start out feeling very similar to the ideas introduced in first-year chemistry especially in the first few weeks of classes but remember that the familiar pieces are stairsteps toward seeing chemistry through an organic chemistry lens. You will establish a tool kit of nomenclature, structure drawing, arrow pushing, vocabulary, and interpretation of data that you will need to use in assessing reactions and proposing syntheses by the end of the course. Responsibilities and Expectations: My philosophy of teaching is built around a mind-set of growth, where learning is fuelled through cycles of practice and feedback. As your course instructor, I aim to facilitate learning of organic chemistry that can scaffold onto your past experiences and awareness of chemistry. I will frequently pose questions in class to establish clarity on your understanding of a topic before we have discussed it thoroughly; by knowing your initial thoughts, we can move forward and discuss details in a way that is responsive and connected to your past knowledge. There will also be chances to add details onto past concepts or refine your way of thinking to help you build a robust set of tools for solving organic chemistry problems. There will be some rote details to learn along the way, to complement and enhance the tools and approaches needed, but the main goal is to build a foundation of understanding of the features and behaviour of organic compounds and how they react. Coursework components of the course (including both individual and team components) are meant to be opportunities for practice and feedback. Coursework should be viewed as lower-stakes assessment tasks where you ll struggle, make mistakes, seek feedback, and formulate questions to fuel your learning--as you prepare for higher-stakes assessments on midterm and final exams. To support learning in this course, you will have an instructional team (instructors and TAs) that you can consult with in class, lab, and tutorial. In this course, we will also have a team of Peer Mentors who will attend some classes and tutorials; Peer Mentors are students who have taken this course before and have come back to help you do well. This is a cumulative course, and content bridges across all course components (class, tutorial, and lab). To help link the learning experiences in class and in tutorial, much of our work in these spaces will be structured around Collaborative Learning Teams. Students will be assigned a team in the first week of classes and will work with this team throughout the semester; more details on Collaborative Learning Teams are provided in the next section, after listing expectations of instructor and students. All learning environments in this course are places for mutual respect. I will do what I can to establish and maintain an environment of mutual respect, and I expect the same from you.
My expectations of you: treat other students, peer mentors, TAs, and instructors with respect arrive prepared and on time to class, lab, and tutorial minimize distraction/disruption for others around you participate actively listen actively be considerate, open, and encouraging of the contributions of others let me know if you are dealing with issues that affect your ability to perform at your best in this class What you can expect from me: treat all students, peer mentors, and instructional team members with respect start and end class on time be available outside class time (e.g. office hours, appointments) to discuss course content or course concerns prepare relevant course materials and post these on D2L in a timely manner reply to emails as soon as possible (will aim to reply within 24 hours, not including weekends) Collaborative Learning Teams: In this class, we will use a team framework to support your learning and connect the lecture and tutorial components of the course. The collaborative learning teams will work together throughout the term on assignments and activities, and this work will contribute 10% to your overall course grade (Coursework Team). Here are the details of how collaborative learning teams will work: 1. Teams will be formed in the first week of classes. I will be using ITP Metrics as a tool to aid team formation and divide the class into teams, based on your tutorial section, previous courses taken, your major/year, work experience, and other factors that will help us form successful teams. I will aim to form diverse teams of 6 people, as diverse teams of this size (5-7 people) have been shown to function best and produce good outcomes. 2. I will put measures in place for a Team Contract and Peer Evaluation to provide individual accountability to the team. A Peer Evaluation Score will be calculated for each student, to be used as a multiplier on the Coursework-Team component of each person s grade. 3. You need to be present with your team, in class or in tutorial, to earn a score on the team activity. When calculating scores at the end of semester, each student will be allotted two absences that won t count toward their score (so, only 2 times during the semester could a student who was absent earn their team s score on the class or tutorial activity). Any other absences will require documentation as per the criteria in the University Calendar for Missed Term Work (Section 3.6 and E.3). 4. If you re having issues in your team, please talk with me as soon as possible. Small problems can become large problems if not addressed early on. I m happy to facilitate a discussion with your team to help resolve issues.
Tutorial Work: Most weeks will involve working in teams during tutorial sessions. These teams are the same ones you ll be working with during class time; tutorials can be viewed as an extension of the learning activities and discussions we have during lecture time. During weeks 3, 5, and 9, the tutorial sessions will be used for Individual Timed Assignments (see schedule and Course Guide for more details), run under exam-like conditions; these are the only weeks of the term where tutorial work will be completed individually. Laboratory Work Laboratory work will be completed individually and will not be performed with your class/tutorial Collaborative Learning Team. Most experiments (aside from Molecular Models and Spectroscopy Experiments) will involve wet experiments where you will take notes in a self-duplicating laboratory notebook during the lab. A duplicate of notes taken during the experiment is to be handed in to your TA at the end of the lab session. Experimental write-ups will follow the instructions laid out in the online lab manual; many of these require print-out and hard-copy completion of a template (may be due at the end of the lab period or at the start of the next lab session, depending on the experiment follow submission deadlines laid out in lab manual). You must earn a passing lab grade (i.e. 50% or greater) to pass the course. Midterm and Final Exams Midterm and Final Examinations will be cumulative, and the format will be a mixture of multiple choice and written responses. At least one past examination will be provided on D2L in advance of the examination, to aid with study preparations. The examination format will be different than the format of exams on the CHEM 351 website archive; however, even though the format is different, the content being examined is the same and thus the archive s questions can be used as a study tool if desired. There are no deferred midterms in this class. See Course Outline for more details of exam regulations.
