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
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
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
Stop by the W. W. Norton Booth at the ACS National Meeting and Expo for a chance to meet Joel Karty and learn more about his mechanistic organization. Ask about our general chemistry texts with unique pedagogy. Hope to see you there!
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
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
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
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
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
Elon professor Joel Karty discusses his observations of how students seem to have more understanding, command, and control of their organic chemistry education when taught via the mechanistic organization. Prof. Karty also talks about being pleasantly surprised by the more interesting questions that students ask after learning elementary steps. Watch this and other videos of … Continue reading How Do Students Respond to the Mechanistic Organization?
