Context-Based Learning (CBL) and learning through developing and using models are two important teaching approaches for chemistry conceptual understanding. We aimed to examine the influence of a CBL approach on students' understanding of Multiple Models of Knowledge Representations ("MMKRs") and "multiple molecular…

Honeybees are a standard model for the study of appetitive learning and memory. Yet, fewer attempts have been performed to characterize aversive learning and memory in this insect and uncover its molecular underpinnings. Here, we took advantage of the positive phototactic behavior of bees kept away from the hive in a dark environment and…

Recently, manuscripts that use bioinformatics tools to convert proteins and other biological materials into music have appeared in several journals. The authors claim that this type of studies adds joy to education of life sciences and attract public attention to biochemistry education along with other uses. We thought the reverse of the process…

A computational laboratory experiment investigating molecular models for hexagonal boron-carbon-nitrogen sheets (h-BCN) was developed and employed in an upper-level undergraduate chemistry course. Students used the Avogadro user interface for molecular editing and the WebMO interface for the quantum computational workflow. Density functional…

In both 2016 and 2019, the NCLEX-RN (National Council Licensure Examination -- RN computerized exam) test plan outlined 15% of content as "pharmacological and parenteral therapies". The test plan also includes physiological sciences. The topics of pharmacology encompass the review of drug action in living organisms, such as humans. As…

Learning to interpret organic structures not as an arrangement of lines and letters but, rather, as a representation of chemical entities is a challenge in organic chemistry. To successfully deal with the variety of molecules or mechanistic representations, a learner needs to understand how a representation depicts domain-specific information.…

The flow of materials and energy through society is an integral but poorly visible element of global sustainability agendas such as the Planetary Boundaries Framework and the UN Sustainable Development Goals (UNSDG). Given that the primary activities of chemistry are to analyze, synthesize, and transform matter, the practice of chemistry has a…

Synthesis and characterization of nanomaterials yields opportunities for instruction of related topics in solution chemistry and materials science, as well as spectroscopy connecting to band theory, the "particle in a box" quantum mechanical model, and thermodynamics. In collaboration with an undergraduate research assistant, we have…

A significant challenge for the global community is the increasing demand for clean and renewable energy technologies. However, a lack of knowledge of these technologies threatens to impede their adoption. The development of cheap, effective, and easy-to-use chemical and electrochemical storage technologies is crucial if countries are to move away…

The use of methanol-water mixtures as solvents for sample preparations is common in many instrumental analytical procedures for compound quantification at trace concentration levels. The reliability of the analytical method depends upon several factors including consistency of instrumental setup and calibration, quality of standards used and…

3D printing was used to prepare space-filling models of electron density isosurfaces and high-resolution molecular models on the basis of the van der Waals radii of atoms. Both model types provide students with kinesthetic simulations of steric effects in bimolecular substitution and elimination reactions. The models can be printed in small sizes…

Autism spectrum disorders (ASD) are common heterogeneous neurodevelopmental disorders, characterized by disruptions in social interactions, communication, and limitations in behavior. Early diagnosis is an important step to prevent progression of ASD. Recent developments in genetic technology provide useful tools to investigate the molecular…

Training "Aplysia" with inedible food for a period that is too brief to produce long-term memory becomes effective in producing memory when training is paired with a nitric oxide (NO) donor. Lip stimulation for the same period of time paired with an NO donor is ineffective. Using qPCR, we examined molecular correlates of brief training…

Nanotechnology will be among the most needed workforce areas in the near future. It is also a creative and highly dynamic field of innovative research areas that displays numerous open fields for future graduates. The central thesis of this paper is to better understand undergraduate engineering students' awareness, exposure, and motivation…

The growing popularity of flipped, blended, and online learning, combined with the need to support a student population with increasingly diverse backgrounds, has led to the development and use of online materials to support students' learning of chemistry outside of a face-to-face classroom. Chemistry simulations provide opportunities to make…
