Direct linkFlynn, Alison B.; Featherstone, Ryan B. – Chemistry Education Research and Practice, 2017
This study investigated students' successes, strategies, and common errors in their answers to questions that involved the electron-pushing (curved arrow) formalism (EPF), part of organic chemistry's language. We analyzed students' answers to two question types on midterms and final exams: (1) draw the electron-pushing arrows of a reaction step,…

Carle, Myriam S.; Visser, Rebecca; Flynn, Alison B. – Chemistry Education Research and Practice, 2020
We developed an online learning module called ''Organic Mechanisms: Mastering the Arrows'' to help students learn part of organic chemistry's language--the electron-pushing formalism. The module guides students to learn and practice the electron-pushing formalism using a combination of interactive videos, questions with instant feedback, and…
