The first time I taught out of Joel’s text, I had no idea where I was going to put the semester break. I enjoyed how well each chapter flowed into the next, but that left me wondering where to put a five-week break. I was used to a traditional ordering of subject which resulted in … Continue reading My Most Productive Start of the Semester Ever
Are Mechanisms Just for Chemistry Majors?
Like many chemists, I am not much help to the biology, biomedical, and medical students that come to my office with queries ranging from anatomy to physiology. Though a prerequisite for my degree, biology was never a true passion of mine. Likewise, many biology majors despise chemistry. In fact, a number of the biology majors … Continue reading Are Mechanisms Just for Chemistry Majors?
Using Lab Reports to Reinforce the Mechanism
My students learn organic chemistry in a mechanistically organized course and I want to make sure they really understand how the mechanisms apply to reactions that are synthetically useful. There are many approaches that I use to reinforce their learning such as quizzes, practice problems, and SmartWork assignments. I previously talked about why I am … Continue reading Using Lab Reports to Reinforce the Mechanism
No More Fearing Alkenes and Alkynes
Since this is the second year I am using Joel’s text, I was sure that I would be comfortable with the syllabus and schedule I set. But I again became nervous as I approached Chapter 11, “Electrophilic Addition to Nonpolar Pi Bonds.” Years of slogging through additions to alkenes and alkynes, working example after example … Continue reading No More Fearing Alkenes and Alkynes
The Right Time for Synthesis?
At Butler, we have four learning goals for our students in organic chemistry: to learn the language, drawing style, and three-dimensional structure of organic molecules; to know and apply organic reactions; to demonstrate understanding of reaction mechanisms; and to integrate this knowledge through synthesis. Of these learning objectives, the most difficult for students to embrace … Continue reading The Right Time for Synthesis?
Mechanisms in Class, Mechanisms in Lab
I have always used a mechanistic approach when teaching organic chemistry. Every class I have taught, I started the first day saying, “Do you want to try to memorize hundreds, if not thousands, of individual reactions, or do you want to learn to understand how about ten reactions take place, so you can apply them … Continue reading Mechanisms in Class, Mechanisms in Lab
Teaching Solvent Effects Early Helps Keep Students’ Heads From Spinning
We started Chapter 9 in class a couple weeks ago, where we learn how to predict the outcome of the SN1/SN2/E1/E2 competition. Similar to how it’s done in most books, we do this by first learning about the major factors that influence the rate of each reaction in this competition. But unlike other books, this … Continue reading Teaching Solvent Effects Early Helps Keep Students’ Heads From Spinning
Memorization Not a Choice: Mechanisms Matter
I have always approached my organic sequence as a mechanism-driven course. Every reaction that we discussed in class started with a mechanism to show how it wasn’t really anything new, but an extension of the types of behaviors we had learned to describe and anticipate. I avoided texts that listed reaction after reaction as completely … Continue reading Memorization Not a Choice: Mechanisms Matter
Cooler Temps, Shorter Days, and the Start of Organic I
I have been teaching organic chemistry for a long time (several years ago I had a wonderful student who pointed out that I taught her dad!). The beginning of first semester of organic chemistry is always clunky and sometimes even painful. How does one make it through the first class without going through every detail … Continue reading Cooler Temps, Shorter Days, and the Start of Organic I
Taking the Frustration out of Online Homework…for You and Your Students
In one of my previous posts, I described how happy I was to implement Norton’s online homework system, Smartwork, for my organic courses. For my students’ learning, nothing beats the instant feedback they get when they click “Check Answer,” which immediately helps them assess whether or not they understand the problem at hand (it’s hard to … Continue reading Taking the Frustration out of Online Homework…for You and Your Students
