A Great Teaching Moment with Aromatic Substitution Reactions

One of my favorite teaching moments throughout the entire year comes in Chapter 23, when, in the same lecture period, we examine aromatic substitution reactions proceeding through three different intermediates: arenium ion intermediates (first reaction below), Meisenheimer complexes (second reaction below), and benzyne intermediates (third reaction below). I love this as a teaching moment because … Continue reading A Great Teaching Moment with Aromatic Substitution Reactions

A Mechanistic Organization is More than Just Mechanistic Patterns

No doubt one of the greatest benefits of teaching a mechanistic organization is the opportunity afforded to students to see patterns among mechanisms—patterns that we experts know and value, but are challenging for students to see under a traditional functional group organization. For example, as I described in my previous post, Why a Mechanistic Organization?, … Continue reading A Mechanistic Organization is More than Just Mechanistic Patterns

Mechanisms and Synthesis Go Hand-in-Hand

In my recent post, Better at Mechanisms, Better at Synthesis, I highlighted research by Alison Flynn at the University of Ottawa, in which she showed that students have better success solving a synthesis problem when they draw reaction mechanisms. I recently had an opportunity to further probe this connection by analyzing my students’ success on … Continue reading Mechanisms and Synthesis Go Hand-in-Hand

Smartwork5: Immediate Formative Assessment Opportunities Help Students Work Smart

Here at Teach the Mechanism we are excited to introduce you to Dr. Christine Pruis, our full-time on-staff Chemistry Subject Matter Expert. In the following post, Dr. Pruis discusses her journey with authoring the Smartwork5 online homework and how this resource facilitates learning and understanding organic chemistry and mechanisms when paired with Joel’s text. Read … Continue reading Smartwork5: Immediate Formative Assessment Opportunities Help Students Work Smart

Bulls-eye: Tracking Reaction Usage Keeps Students on Target with Synthesis Problems

There are no two ways about it—solving synthesis problems is one of the more challenging tasks that students face in organic chemistry. One reason for the difficulty is the sheer number of reactions we deal with throughout the year, perhaps a few hundred in total. Invariably my students ask me if they need to know … Continue reading Bulls-eye: Tracking Reaction Usage Keeps Students on Target with Synthesis Problems

Winds of Change: Instructor Resources Make Switching to Karty a Breeze

I imagine any professor considering changing to a new textbook goes through the same dilemmas I did when I decided to switch. Even when we find a book that we know will benefit our students, we also know that there will be a time cost in making the transition. Faculty at schools of all sizes … Continue reading Winds of Change: Instructor Resources Make Switching to Karty a Breeze

Better at Mechanisms, Better at Synthesis

I have long maintained that a greater mastery of mechanisms aids students in solving synthesis problems. The idea makes sense: the better a student understands how a reaction takes place via the mechanism, the better he or she will be able to incorporate that reaction into a synthesis when a specific modification to a molecule … Continue reading Better at Mechanisms, Better at Synthesis

Memorization Not a Choice: Learning to Remember

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: Learning to Remember

Flipping the Script: Mechanistic Organization Encourages Cooperative Learning

When I first heard Joel Karty speak about his mechanistic organization in his organic chemistry text around 2016,  I had also heard a lot of buzz about flipping the classroom. I was very curious about trying this in my own classroom, but implementing self-directed learning with a more intricate discipline like organic chemistry can seem … Continue reading Flipping the Script: Mechanistic Organization Encourages Cooperative Learning

In Favor of Putting Pen to Paper

With the advent of increasingly sophisticated, convenient, and useful online homework programs, is there any place left for the classic pencil and paper textbook problems? I will have to preface this by going ahead and stating my general biases. Probably the most effective way to do this would be to tell you all that in … Continue reading In Favor of Putting Pen to Paper
