Description of Course Goals and Curriculum
CHM 202 is a part of the first year chemistry sequence but touches on very different concepts and skills compared to those learned in CHM 201. CHM 201 is more mathematically based (thermochemistry and enthalpy calculations, etc.) while CHM 202 approaches the more theoretical side of chemistry, explaining why certain colors exist and how electron transitions create these color appearances, etc.
The main goal of this course is to introduce students how to begin to think like a chemist. In effect, the theoretical aspect of the course guides the class and may consequently be easier to follow/stay on top of due to the minimal mathematical emphasis, compared to CHM 201.
Learning From Classroom Instruction
Professor L’Esperance did a majority of the teaching for the Spring 2016 course, with some aid from Professor Chan. The main difference between CHM 201 and CHM 202 lectures is the format in which they are presented. In CHM 201, Professor Hecht uses detailed power points for every lecture and uploads the material on blackboard. In CHM 202, Professors L’Esperance and Chan write all lecture material on the boards, so handwritten notes are crucial. In this way, it is important to take good, legible notes. I would recommend collaborating with other students on certain lectures if you find a hard time following the material as it is sometimes helpful to see how other students take notes compared to your own method.
Learning For and From Assignments
Similar to CHM 201, CHM 202 continues the weekly homework assignments (due on either Tuesdays or Thursdays), consisting of a set number of textbook problems paired with two - three written problems from the TA’s and/or professor. The theme of CHM 202 is theoretical and therefore the homework follows a similar pattern. Instead of different mathematical approaches to solve problems, homework questions in CHM 202 will be answered in more “big-picture” generality that explains the particular topic at hand.
There may still be some math dispersed in the material, but not nearly to the extent that it was emphasized in CHM 201. The exams in CHM 202 follow a very similar format to CHM 201, in both the schedule of exams (two midterms + final + lab practical + written lab final) and the format (multiple short answer questions).
McGraw is an extremely helpful resource for this class and I recommend getting plugged in to a group study hall early in the semester. There are lots of tutors who have previously taken CHM 202 are eager to help with any questions or difficulties you may have. I recommend seeking help in McGraw study halls or McGraw individual tutoring more than one day before the homework is due or before an exam as it will allow you more time to learn the material (and the study halls will be less crowded). McGraw is an awesome external resource for CHM 202 and I highly recommend taking full advantage of it to heighten your success in the course.
What Students Should Know About This Course For Purposes Of Course Selection
This class is extremely similar to CHM 201/207 in terms of time commitment and overall course scheduling/format. Do not be intimidated by the course if you found CHM 201 particularly difficult as CHM 202 emphasizes a different way of thinking about the material introduced. Many students take this class in the spring of their freshman or sophomore year, usually with another science or lab, so it is not a big deal if you’re worried about taking CHM 202 with another time-demanding or challenging course.
