We have developed a learning unit based on the Standard Model of particle physics, featuring novel typographic illustrations of elementary particles and particle systems. Since the unit includes antiparticles and systems of antiparticles, a visualization of anticolor charge was required. We propose an alternative to the commonly used…

The "Yet Another extended Hu¨ckel Molecular Orbital Package" (YAeHMOP) has been merged with the Avogadro open-source molecular editor and visualizer. It is now possible to perform YAeHMOP calculations directly from the Avogadro graphical user interface for materials that are periodic in one, two, or three dimensions, and to visualize…

There is a growing need for public understanding about groundwater resources. Knowing what groundwater and aquifers are is fundamental to understanding more complex issues such as groundwater quality and availability. However, groundwater and related concepts are among the topics that instructors most struggle to teach. Although constructivist…

A laboratory is a large investment of time and money for departments of chemistry yet discussions continue about its purpose in the educational process. Helping students navigate the three levels of representation; macroscopic, particulate and symbolic is a potential use of this time. This study looked at two different types of visualization for…

In sound symbolism, a word's sound induces expectations about the nature of a salient aspect of the word's referent. P. Walker (2016a) proposed that cross-sensory correspondences can be the source of these expectations, and the present study assessed three implications flowing from this proposal. First, sound symbolism will embrace a wide range of…

Synergistic learning combining computational thinking (CT) and STEM has proven to be an effective method for advancing learning and understanding in a number of STEM domains and simultaneously helping students develop important CT concepts and practices. We adopt a design-based approach to develop, evaluate, and refine our Collaborative,…

Skills in science, technology, engineering, and mathematics (STEM) are increasingly in demand. Theoretical knowledge and formulas alone are frequently not sufficient to understand complex phenomena. Simulations are a valuable tool to support the conceptual understanding by visualizing invisible processes. The constant interaction with the learning…

Numerical simulations are playing an increasingly important role in modern science. In this work it is suggested to use a numerical study of the famous perihelion motion of the planet Mercury (one of the prime observables supporting Einsteins general relativity) as a test case to teach numerical simulations to high school students. The paper…

Unlike the large number of laboratory experiments on phase-transfer catalysis (PTC) that focus on a catalyzed chemical process, the present laboratory emphasizes the mechanism of phase transfer catalysis itself. Students can follow visually the actual transfer of the reagent by the catalyst, and its consumption in the organic phase, in a…

Engaging students in conversations around science and engineering design can be challenging. Sparking such conversations during field trips at an interactive science center has additional challenges. First, students vary considerably in age from day to day: science center employees might work with first graders one day and sixth graders the next.…

Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

The purpose of this study was to investigate not only the effectiveness of dynamic versus static visualizations on learning star motions but also the influence of students' spatial abilities with these two types of visualizations on their learning. We assigned 155 fifth-grade students to either a dynamic or a static condition. We used a science…

"How does an aircraft fly?" is one of the most frequently asked science questions by young pupils. The lift on airplane wings also makes a great example of the application of the Bernoulli principle while teaching fluid mechanics in introductory physics and engineering courses. The topic is of great interest and is therefore covered in…

Research into the efficacy of modules featuring dynamic visualizations, case studies, and interactive learning environments is reported here. This quasi-experimental 2-year study examined the implementation of three interactive computer-based instructional modules within a curricular unit covering cellular biology concepts in an introductory high…

The aim of the present study is to determine pre-service teachers' mental models related to basic astronomy concepts. The study was conducted using a survey method with 293 pre-service teachers from 4 different departments; physics education, science education, primary teacher education and early childhood education. An achievement test with…
