Recent advancements in computer graphics and hardware have driven the resurgence of virtual reality (VR). Past literature has reported the use of VR in education, especially for teaching spatially complex concepts. However, there are limited data available on the precise role of VR game design elements. In this study, we introduce a new VR game,…

Purpose: This study reports on the effectiveness of using animated computer graphics to teach submicroscopic level science to secondary school (Form One) students. Method: A total of fifty-three secondary school (Form One) students of average spatial ability were selected to participate in this study. Three topics involving concepts at the…

This work combines laboratory quantitative analysis of colored solutions and common devices for digital imaging (digital or web cameras or mobile phones, i.e., smartphones). ColorX software, specially designed for this study, was used for data collection and analysis in order to calculate concentrations of colored solutions from measured RGB…

This paper presents a teaching kit that combines the fabrication of a low-cost microcontroller-based potentiostat and a LabVIEW-generated graphical user interface. The potentiostat enables undergraduate-level students to learn electroanalytical techniques and characterize energy conversion devices such as solar cells. The purpose of this teaching…

The quantitative evaluation of experimental data and their graphical presentation are integral to teaching and research in chemistry and the life sciences. Data are commonly fitted to physical models, which in all but the simplest cases are expressed as nonlinear mathematical functions. To facilitate data evaluation in both teaching and research…

This paper presents a programming project named NMRviewer that allows students to visualize transformed and processed 1 H NMR data in an accessible, interactive format while allowing instructors to incorporate programming content into the chemistry curricula. Using the MATLAB graphical user interface development environment (GUIDE), students can…

Introductory chemistry students often have difficulty visualizing the 3-dimensional shapes of the hydrogenic electron orbitals without the aid of physical 3D models. Unfortunately, commercially available models can be quite expensive. 3D printing offers a solution for producing models of hydrogenic orbitals. 3D printing technology is widely…

Thermodynamic processes are complex phenomena that can be understood as a set of successive stages. When treating processes, classical thermodynamics (and most particularly, the Gibbsian formulation, predominantly used in chemistry) only pays attention to initial and final states. However, reintroducing the notion of process is absolutely…

Molecular model kits have been used in chemistry classrooms for decades but have seen very little recent innovation. Using 3D printing, three sets of physical models were created for a first semester, introductory chemistry course. Students manipulated these interactive models during class activities as a supplement to existing teaching tools for…

In our three-dimensional world, one can plot, see, and comprehend a function of two variables at most, V(x,y). One cannot plot a function of three or more variables. For this reason, visualization of the potential energy function in its full dimensionality is impossible even for the smallest polyatomic molecules, such as triatomics. This creates…

The advantages of Gaussian-type orbitals (GTO) over Slater-type orbitals (STO) in quantum chemistry calculations are clarified here by means of a holistic approach. The popular Microsoft Office Excel program was used to create an interactive application with which students are able to explore the features of GTO, including automatic calculations…

Efforts to make effective use of technology offer a promising direction for science education research. In this study, we investigated how a teacher and students used an inquiry-based, visualization-focused chemistry unit. The chemistry unit was designed for American students and takes advantage of dynamic, interactive computer visualizations.…

Instructions are given for building physical scale models of ordered structures of B-form DNA, protein [alpha]-helix, and parallel and antiparallel protein [beta]-pleated sheets made from colored computer printouts designed for transparency film sheets. Cut-outs from these sheets are easily assembled. Conventional color coding for atoms are used…

The present investigation was designed to determine if the learning benefits of metaphors and graphics could be combined into one instructional device--a metaphorical graphic--to aid in the acquisition of difficult concepts of chemistry. The authors further sought to determine if metaphorical graphics could foster greater retention of the basic…

Explains molecular graphics, i.e., the application of computer graphics techniques to investigate molecular structure, function, and interaction. Structural models and molecular surfaces are discussed, and a theoretical model that can be used for the evaluation of intermolecular interaction energies for organometallics is described. (45…
