Virtual reality (VR) lab experiences for organic chemistry were developed at NC State University as an accessibility tool for students who are unable to attend in-person laboratories due to disabilities, attendance challenges such as pregnancy or military deployment, or safety concerns. The resulting first-person VR experiences are immersive and…

The Reaction Coordinate Diagram Inventory (RCDI) was developed to measure chemistry students' thinking and confidence when interpreting the kinetic and thermodynamic information encoded within reaction coordinate diagrams (RCDs). The RCDI was designed based upon analyses of qualitative data collected in semi-structured interviews with general…

In response to the Coronavirus-19 pandemic, higher education institutions quickly moved to emergency remote learning, and most human subjects research came to an immediate halt. Chemistry education researchers who wanted to continue data collection were confronted by many challenges, including research designs and data collection methods that had…

The Reaction Coordinate Diagram Inventory (RCDI) has been developed to measure student thinking and confidence with reaction coordinate diagrams (RCDs) and their correspondence to reaction mechanisms. The RCDI was designed using a sequential mixed-methods protocol, such that the questions and distractors in the instrument were generated based on…

This article describes the development of the Quantization and Probability Representations Inventory (QuPRI) as a measure of student understanding of the electron structure of the atom. The QuPRI was created using a mixed-method sequential design such that the items and distractors were generated on the basis of the analysis of semi-structured…

Learning thermodynamics requires understanding abstract topics such as entropy and spontaneity. Students tend to rely on metaphors and everyday meanings to reason about these topics. This study investigates how students explain dissolution and precipitation using the concepts of entropy and spontaneity. Students from general chemistry, physical…

The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

Multifunctional chemical analysis (MCA) systems provide a viable alternative for large scale instruction while supporting a hands-on approach to more advanced instrumentation. These systems are robust and typically use student stations connected to a remote central computer for data collection, minimizing the need for computers at every student…

Thirty-six students enrolled in Organic Chemistry II participated in individual, semistructured, think-aloud interviews about the factors that contribute to the stability and reactivity of organic species in the context of unimolecular and bimolecular nucleophilic substitution and elimination reactions. The students were provided with the…

The purpose of this study was to analyze organic chemistry students' annotations of reaction coordinate diagrams to better understand how they sought connections between reactions and reaction coordinate diagrams. Thirty-six students enrolled in Organic Chemistry II participated in semistructured, think-aloud interviews that asked students to…

This study investigates how students account for a macroscopic temperature change during the dissolution of ionic salts through particulate level explanations. Semi-structured interviews were conducted with general chemistry, physical chemistry, and biophysical chemistry students. During the interviews, students conducted hands-on tasks that…

A structured inquiry experiment for inorganic synthesis has been developed to introduce undergraduate students to advanced spectroscopic techniques including paramagnetic nuclear magnetic resonance and electron paramagnetic resonance. Students synthesize multiple complexes with unknown first row transition metals and identify the unknown metals by…

Although stereochemistry is an important topic in second-year undergraduate organic chemistry, there are limited options for laboratory activities that allow direct visualization of macroscopic chiral phenomena. A novel, guided-inquiry experiment was developed that allows students to explore chirality in the context of cholesteric liquid crystals.…

Meaningful learning requires the integration of cognitive and affective learning with the psychomotor, i.e., hands-on learning. The undergraduate chemistry laboratory is an ideal place for meaningful learning to occur. However, accurately characterizing students' affective experiences in the chemistry laboratory can be a very difficult task. While…

Research on laboratory learning points to the need to better understand what and how students learn in the undergraduate chemistry laboratory. The Meaningful Learning in the Laboratory Instrument (MLLI) was administered to general and organic chemistry students from 15 colleges and universities across the United States in order to measure the…
