We started resonance structures in class today. It wasn’t until after class had ended that I realized how many great teaching moments we had, and I attribute those teaching moments to the way resonance is presented in my textbook. Resonance is introduced in Chapter 1, and students are taught to draw resonance structures by first … Continue reading The Features of Resonance and the Teaching Moments They Lead To
As a new fall semester dawns, my mind turns inevitably to the fresh crop of students that will soon be struggling with Lewis structures containing many more atoms than they are accustomed to. Teaching at a community college brings some advantages, like having organic students that you have taught through both semesters of the general … Continue reading A New Semester, A fresh Foundation
Karty’s mechanistic approach to organic chemistry provides the content organization to facilitate student success. In a functional group approach students are more likely to apply an incorrect mechanism to solve a synthetic problem. This is because classification by functional group does not provide an organizational level that allows students to classify reactivity. Organization by functional … Continue reading Building on their Knowledge: From Atoms to Multi-Step Synthesis to Curing Sick Puppies
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
When I was in ninth grade, my family built a house. I remember my dad, who is an engineer, regularly checking on the progress and quality of the foundation. He knew that the foundation was the most important part of the house. Building a proper foundation took a lot of time, but it was important … Continue reading Building a Solid Foundation Gives the Student More Confidence
One of the things my students find most challenging about aromaticity is whether to include lone pairs as part of a cyclic π system. If a lone pair is included, then the number of π electrons increases by two, and a student’s prediction about whether a species is aromatic will also change. What I think … Continue reading Lone Pairs and Aromaticity
Early in my teaching career I realized that a large percentage of my organic chemistry students weren’t carrying forward nearly as much from their general chemistry course as I had expected. This is a potentially enormous problem because without command of, and the ability to apply, several concepts from general chemistry, students will find it … Continue reading What Role Should the Organic Textbook Play in Helping Students Transition From General Chemistry?
