摘要：
The transition from general chemistry to organic chemistry is challenging for many students. To succeed, students must remember their foundational chemistry skills and effectively transfer that knowledge into the context of organic chemistry. However, this transition is often hindered by many obstacles: (1) lack of prerequisite knowledge, (2) lack of understanding how foundational chemistry knowledge is applicable to organic chemistry, and (3) high levels of anxiety and low levels of self-efficacy toward organic chemistry. To address these challenges, a peer-led summer program that leverages question-embedded videos, worksheets, and synchronous remote webinars to enhance students' transition into organic chemistry was developed and assessed. This six-week program, OrgoPrep, covers a wide set of introductory organic chemistry topics: resonance structures, hybridization and moleculer shape, molecular orbitals, acid-base chemistry, limiting reagents, and more. Substantial benefits, such as decreasing student anxiety and doubling student self-efficacy, were observed for students who completed OrgoPrep. These students also significantly outperformed their peers who did not participate in the program, despite having no statistical difference in prior chemistry abilities-OrgoPrep students had a 3-fold decrease in failing grades and a 2-fold increase in A grades. Overall, OrgoPrep successfully serves as a bridge between general and organic chemistry, while facilitating knowledge transfer and enhancing student self-efficacy.
