The reconstruction of two-dimensional (2D) slices to three-dimensional (3D) digital anatomical models requires technical skills and software that are becoming increasingly important to the modern anatomist, but these skills are rarely taught in undergraduate science classrooms. Furthermore, learning opportunities that allow students to…

Synthesis of (Z)-alkenes is challenging because the (E) stereoisomers are usually more stable. Energy transfer photocatalysis has emerged as an efficient strategy for (E) [right arrow] (Z) alkene isomerization. We report the development of an advanced undergraduate laboratory experiment that introduces students to contemporary organic…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…

This paper presents an analysis of the use of multimedia and hands-on models on university students' understanding of stereochemistry. The relationship between students' scientific reasoning skills and their understanding of stereochemistry was also determined. Two groups of second-year chemistry students from the State University of Malang taking…

Dynamic biochemical processes are often difficult for students to grasp in the classroom using static images or models, or even through watching simulation videos. This is particularly true for protein-folding and enzyme catalysis, two key biochemistry concepts. The author has developed and tested two 3D, dynamic, and interactive classroom models,…

Contribution: This article explores how the Industrial Internet of Things (IIoT) could be leveraged to enhance the teaching/learning experience of advanced control techniques [e.g., model-predictive control (MPC)] for complex systems (nonlinear and multivariable) for undergraduate students. Background: The IIoTs' features, such as ubiquitous…

The Life Sciences Learning Center (LSLC) is a hands-on science outreach center located at the University of Rochester's School of Medicine and Dentistry (UR-SMD) in Rochester, New York. The LSLC provides hands-on, case-based learning to boost science literacy and increase enthusiasm toward science learning. The LSLC offers on-site and in-school…

As part of COVID-19 preparedness, a student-developed, Android-based app was used as a pre-laboratory learning aid for a molecular modeling laboratory in a first-year general chemistry course. A worksheet activity with trigger codes and questions related to spatial features of transition metal complexes was designed. Using the Transition Metal…

The authors describe the construction and use of tactile models for demonstrating intermolecular forces. These models are composed of inexpensive materials and can be used in college chemistry classrooms of varying levels including general and organic chemistry. The models were designed to be paired with an accompanying activity to encourage…

For many reasons, physiological aspects of anatomy and physiology laboratories are often presented as simulations. While simulations effectively convey concepts, hands-on activities promote more active student engagement. Recycled soda bottles, supplemented with other inexpensive readily available supplies, can be used to create working models…

Acquiring a basic understanding about the composition of crystal structures and the resulting structure-property relationship is central for chemists and material chemists, enabling the prediction of desired properties and the solution of a wide range of current challenges in sciences, e.g., the development of clean-energy storage. For a deeper…

Sets of models of molecules (which are of interest for teaching molecular structure, symmetry, and related topics in many chemical disciplines) were prepared and made available either for self-directed 3D-printing or through the 3D-printing company Shapeways providing 3D-printing as a service. This allows teachers to save time on searching for…

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…

The first phase of this multiphase study involves modeling of college students' thinking of friction at the microscopic level. Diagnostic interviews were conducted with 11 students with different levels of physics backgrounds. A phenomenographic approach of data analysis was used to generate categories of responses which subsequently were used to…
