Syllabus
O-Chem Lab I, CHEM 222, SU-A-2023
Welcome
This class welcomes participation from any student who has satisfied the appropriate prerequisites, described below. Students journey to this course along many different pathways with a range of abilities, skills, knowledge, experiences, and expectations. We invite students to ask questions. Asking questions helps to clear the path of obstacles for you and for others. Your input contributes to a healthy teaching and learning environment. Diverse intellectual engagement helps your teachers to thoughtfully construct educational materials, instructions, delivery style, and thereby grow professionally. Contact me, christine.dimeglio@yale.edu, to discuss strategies for your best performance. With respect to materials required for in-person participation, don’t let finances or slow postal delivery stand in your way. If you need a lab coat, reach out.

Prerequisites
The Department of Chemistry strictly enforces prerequisites for chemistry laboratory courses. Students must have received a grade for General Chemistry CHEM 134L and 136L, or their equivalents, such as a college course elsewhere or the Chemistry Department placement exam. Organic Chemistry Lecture I (CHEM 220 or CHEM 174 or their equivalents) is a pre-requisite or co-requisite. When in doubt, contact the instructor or the DUS of chemistry

Course Location and Hours
Canvas
Canvas is the learning management platform used to facilitate communication of all course content. The important features of our course Canvas site that enable us to work together effectively include:
Announcements: Important course information is posted here for the group and delivered to your Yale email account.
Modules: Modules, organized by lab week, organizes all curricular course content including links to prerecorded materials, assignments, and assessments.
Required Materials
Technology that allows access to Canvas, Zoom, Word, Excel. The ability to convert student work to pdf files and the ability to use Google Chrome or Mozzilla for taking Canvas quizzes. Phone camera for taking photos of spectra and set ups, and converting lab notes to pdf files.
If you are in lab with improper clothing, you will need to leave, change, come back to finish. We suggest keeping a change of lab clothes in the lab for the summer session since we are the only group using the space/drawers all session.
LOCK for backpack/coat lockers. Backpacks and coats are not permitted in lab. The lockers are in the hallways outside of the lab rooms. Protect your belongings from thieves! However, you must remove your lock and your belongings at the end of lab.
Materials Supplied by the Lab
Loner lab coats if you spill something on yours while in lab.
Disposable surgical masks for in-lab use only.
Assignments
Post lab assignments (PL): Post lab assignments require reading of assigned primary literature, and thoughtful responses to a series of questions about the experiments performed in lab.
Quizzes (Q): Students take quizzes on Thursdays in the open window of 5pm to 11:50 pm. Quizzes are 10 minutes in length, multiple choice, delivered by Canvas. If a student missed their quiz, they receive a 20% deduction and another opportunity to take the quiz on the following day. Students with SAS accommodations for extra time should reach out with their specific time accommodation. Paperwork can follow later.
Grading
Quizzing
Additional information:
Attend every scheduled session on time.
Complete all experimentation with integrity and with attention to their safety and the safety of others.
Grades ranges are determined based on [total points earned – penalty deductions]/total points available. Scaling is applied as appropriate for each TA’s student group. Students who receive multiple penalty deductions position themselves for earning B- and lower grades.
Penalties Deductions are assessed for:
Submitting graded assignments after the due date/time. The deduction is 5% per day beginning at the due date/time. Work is always due on your regularly scheduled lab day, even if you are sick. This policy prevents what we call, “illness of convenience”. If you have an exceptional situation, let’s talk.
Questions about graded assignments
Academic Integrity
It is the goal of the Chemistry Department Teaching Staff to assist all students in their personal and professional growth. Breaches in academic integrity undermine our goal. Knowing the rules of academic integrity and applying those rules to your conduct, bench work, and written submissions is integral to your advancement as a scientist. You will be asked to read and sign out academic integrity policy before we begin working together. A copy of our policy can be found at our Canvas Home Page.
