London dispersion (LD) interactions are the main contribution of the attractive part of the van
der Waals potential. Even though LD effects are the driving force for molecular aggregation …

We suggest a scale of dispersion energy donors (DEDs) that allows for direct comparisons
with steric effects. This scale is based on the classic A-values and allows groups to reorient …

This three-year study builds on prior work analyzing students' causal mechanistic
explanations about acid–base reactions. Here we extend that work to characterize and …

Reaction mechanisms are a core component of organic chemistry. Being able to handle
these mechanisms is a central skill for students in this discipline. Diagnosing and fostering …

What we emphasize and reward on assessments signals to students what matters to us.
Accordingly, a great deal of scholarship in chemistry education has focused on defining the …

Acid–base chemistry is a key reaction motif taught in postsecondary organic chemistry
courses. More specifically, concepts from the Lewis acid–base model are broadly applicable …

Three-dimensional learning is the name given to the vision for science education described
in the National Academies consensus report A Framework for K–12 Science Education. Of …

The use of large language model Generative AI (GenAI) systems by students and instructors
is increasing rapidly, and there is little choice but to adapt to this new situation. Many, but not …

Despite problem solving being a core skill in chemistry, students often struggle to solve
chemistry problems. This difficulty may arise from students trying to solve problems through …

Response process validity evidence can provide researchers with insight into how and why
participants interpret items on instruments such as tests and questionnaires. In chemistry …
