Safety training and assessment programs play a key role in inducing safe behavior on construction sites. The traditional training methods are fraught with limitations. The advent of visualization technologies such as building information modeling (BIM) and virtual reality (VR) lay a great promise in imbuing vigor in the training and assessment…

A spectrogram of a singer's vibrato presents a striking way to introduce students to frequency, Fourier spectra, and modulation. Vibrato is discussed from the perspectives of the physicist and the musician. A dramatic spectrogram is included where coauthor soprano Michel suppresses her vibrato so that acoustical characteristics can be compared to…

Topological data analysis (TDA) is a collection of powerful tools that can quantify shape and structure in data in order to answer questions from the data's domain. This is done by representing some aspect of the structure of the data in a simplified topological signature. In this article, we introduce two of the most commonly used topological…

Virtual images are often introduced through a "geometric" perspective, with little conceptual or qualitative illustrations, hindering a deeper understanding of this physical concept. In this paper, we present two rather simple observations that force a critical reflection on the optical nature of a virtual image. This approach is…

A new program, ECEP2D, for simulating the one-dimensional (1D) and two-dimensional (2D) patterns of the gel electrophoresis of a protein after it has been digested by one or more enzymes is introduced. With ECEP2D, students can gain deeper insights into gel electrophoresis by performing hands-on simulations. For example, students can visualize how…

Results from a number of studies indicate that the type of light generated by the reflection on the surface of different types of surfaces can influence the spatial visualization ability; however, research provides inconsistent results. Considering this, a quasi-experimental study was conducted to identify the existence of statistically…

The definition of visualization in engineering graphics has evolved over the years due in part to extensive research in visualization by the engineering design graphics profession. The literature indicates research in the areas of engineering graphics and the use of visualization has grown from improvement of visualization skills and the…

This study makes an effort to map the development of previous academic studies on picturebooks in order to provide an overview of contemporary picturebook research utilizing the HistCite (ver. 12.03.17) software. The findings are based on an analysis of 9,763 references to 286 articles from 175 journals indexed by the Web of Science (WoS)…

Handwriting dysfunction can negatively impact a child's occupational performance. Data supporting handwriting interventions are limited, and a need exists for evidence-based handwriting interventions to enhance a child's functional performance and participation in meaningful occupations. This pilot study examined the relationship between the…

Big data analytics are prevalent in fields like business, engineering, public health, and the physical sciences, but social scientists are slower than their peers in other fields in adopting this new methodology. One major reason for this is that traditional statistical procedures are typically not suitable for the analysis of large and complex…

It has been shown that motor coordination training can enhance performance in spatial cognition tasks. This was investigated in an applied setting. Twenty-eight office workers attended either cognitive motor coordination training or core-stability training for one hour every week for six weeks. Before and after training, mental rotation and…

The use of visualisation techniques in teaching has enabled students to improve their memory and comprehension of written narratives. Psychological research reveals how various factors can influence visualisation and learning, including; adopting a character's perspective; constructing self-related images; multi-sensory text representing episodic…

For more than 10 years, I had taught Kepler's laws and the law of universal gravity without a corresponding experiment. I sometimes remember how these topics were difficult for me in my high school days to understand. At that time, I thought that one of the reasons for my difficulty was that these phenomena cannot be visualized using physical…

In the core of computational thinking (CT) practices is problem-solving. However, there is little research on connecting CT with problem solving processes. We developed a computer-based assessment on CT that can log students' problem-solving processes and administered it to a group of fifth graders as a pre- and post- measure of a robotics…

The ability to analyze arguments is critical for higher-level reasoning, yet previous research suggests that standard university education provides only modest improvements in students' analytical-reasoning abilities. What pedagogical approaches are most effective for cultivating these skills? We investigated the effectiveness of a 12-week…
