Direct linkHua, Amy K.; Lakey, Pascale S. J.; Shiraiwa, Manabu – Journal of Chemical Education, 2022
This paper presents MATLAB user interfaces for two multiphase kinetic models: the kinetic double-layer model of aerosol surface chemistry and gas--particle interactions (K2-SURF) and the kinetic multilayer model of aerosol surface and bulk chemistry (KM-SUB). Each interface has simple and user-friendly features that allow undergraduate and…

White, Holly; Forbes, Cory T. – Journal of Geography in Higher Education, 2023
Undergraduate students may possess underdeveloped knowledge about water systems, particularly groundwater. The use of models and modeling have been employed in undergraduate classrooms to support students' learning about water. However, effective modeling requires spatial thinking skills, which undergraduate students may also need to develop.…

Lau, Poh Nguk; Chan, Wen Loong; Li, Yuxuan – Journal of Chemical Education, 2022
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 high Arctic is a remote place, where geoscientific research and teaching require expensive and logistically demanding expeditions to make use of the short field seasons. The absence of vegetation facilitates the use of modern photogrammetric techniques for the cost-effective generation of high-resolution digital outcrop models (DOMs). These…

This paper focuses on examining the effectiveness of three-dimensional (3D) computer models on student teachers' academic achievement, mental model construction, and spatial ability used in learning the "atomic models" topic in this study. The students were randomly assigned into two groups: the treatment group (TG) where 3D computer…

Yan, Zixiang; Xia, Heming; Lan, Yueheng; Xiao, Jinghua – Physics Education, 2018
A cylinder rolling down an inclined board is a commonly seen and interesting object to study and it is also easy to experiment with and model. Following what has become a popular practice, we use smartphones to measure the angular acceleration of a cylinder rolling down a plane of different inclining angles. The friction force deviates from the…

Schmid, Jonas R.; Ernst, Moritz J.; Thiele, Gu¨nther – Journal of Chemical Education, 2020
We present an accessible implementation of augmented reality projections for the depiction of complex structures and motifs, including atomic orbitals and elemental allotropes. The utilization of a free, cross-platform-compatible, online database of these structures provides the access route for closer examination, either via augmented reality or…

Harris, Patricia Ann – ProQuest LLC, 2019
Spatial intelligence is an essential skill commonly used within various fields of science. Students with low spatial abilities frequently struggle to identify, retrieve, and apply key complex abstract information presented as multiple representations to actual three-dimensional natural materials and phenomena. Spatial ability may be considered a…

Lozano-Parada, Jaime H.; Burnham, Helen; Martinez, Fiderman Machuca – Journal of Chemical Education, 2018
A classical nonlinear system, the "Brusselator", was used to illustrate the modeling and simulation of oscillating chemical systems using stability analysis techniques with modern software tools such as Comsol Multiphysics, Matlab, and Excel. A systematic approach is proposed in order to establish a regime of parametric conditions that…

Luo, Wei; Smith, Thomas J.; Whalley, Kyle; Darling, Andrew; Ormand, Carol; Hung, Wei-Chen; Chiang, Jui-Ling; Pelletier, Jon; Duffin, Kirk – British Journal of Educational Technology, 2019
This paper presents results from a randomized experimental design replicated over four semesters that compared students' performance in understanding landform evolution processes as measured by the pretest to posttest score growth between two treatment methods: an online interactive simulation tool and a paper-based exercise. While both methods…

Behmke, Derek; Kerven, David; Lutz, Robert; Paredes, Julia; Pennington, Richard; Brannock, Evelyn; Deiters, Michael; Rose, John; Stevens, Kevin – Proceedings of the Interdisciplinary STEM Teaching and Learning Conference, 2018
Spatial reasoning is defined as the ability to generate, retain, and manipulate abstract visual images. In chemistry, spatial reasoning skills are typically taught using 2-D paper-based models, 3-D handheld models, and computerized models. These models are designed to aid student learning by integrating information from the macroscopic,…

Heikkinen, Lasse; Savinainen, Antti; Saarelainen, Markku – Physics Teacher, 2016
The ray tracing method is widely used in teaching geometrical optics at the upper secondary and university levels. However, using simple and straightforward examples may lead to a situation in which students use the model of ray tracing too narrowly. Previous studies show that students seem to use the ray tracing method too concretely instead of…

Gomez, Elaine; Paul, Melissa; Como, Charles; Barat, Robert – Chemical Engineering Education, 2014
This experiment and analysis offer an effective experience in greenhouse gas reduction. Ammoniated water is flowed counter-current to a simulated flue gas of air and CO2 in a packed column. The gaseous CO2 concentrations are measured with an on-line, non- dispersive, infrared analyzer. Column operating parameters include total gas flux, dissolved…
