Three-dimensional (3D) scanning and printing technology has allowed for the production of anatomical replicas at virtually any size. But what size optimizes the educational potential of 3D printing models? This study systematically investigates the effect of model size on nominal anatomy learning. The study population of 380 undergraduate…

There's a lot of debate in the Montessori community about the use of technology for children. But the COVID-19 pandemic forced many people to get comfortable with learning online--and now the number of learners in online programs is on the rise. K. T. Korngold examines how her father, Bob Korngold, was an early advocate for technology in…

Learning to write chemical formulas of compounds is a basic and indispensable part of understanding and studying chemistry. However, it is hard for students with visual impairment to assess and learn molecular arrangements and formulas. For the convenience of such students with special needs, it is necessary to come up with easy, comprehensive,…

In recent decades, the application and adaptation of new technologies have gradually become invaluable in education. When the students are visually impaired, the use of these technologies becomes even more valuable. In this line, a theoretical-practical workshop on human evolution was carried out with 25 students from the Spanish National…

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…

An open-source repository of basic building block models design files for writing chemical formulas, equations, and ionic states are provided. Writing chemical symbols, molecules, and ions in their correct oxidation state or valency in chemical equations is an essential and integral part of learning. For a visually impaired student, it is very…

This research examined the role of touch in creative media production in the context of educational and community makerspaces. Touch, while only recently explored in digital media production, is a crucial perceptive sense through which to experience the world, particularly in two- and three-dimensional making, and to explore texture, temperature,…

A reference electrode is an essential component of all three-electrode electrochemical measurements. Common commercial reference electrodes, including the saturated calomel electrode and Ag/AgCl reference electrode, are expensive with the former containing toxic mercury. Cheaper alternatives have been proposed including Ag/AgCl references made…

As three-dimensional (3D) printing technology is fast becoming more affordable and accessible, calculus instructors can now consider using 3D printing and 3D printed models to actively engage students in core concepts relating to objects in R[superscript 3]. This article describes three lessons for a multivariable calculus class in which students…

In this article, the authors present early research in using 3-D printing to develop tactile experiences to improve understanding and enable broader aesthetic participation in arts learning contexts for all learners that would benefit from tactility and in particular those with low vision. Their exploration of 3-D printing to create assistive…

Protein ORIGAMI (http://ibg.kit.edu/protein_origami) is a browser-based web application that allows the user to create straightforward 3D paper models of folded peptides for research, teaching and presentations. An amino acid sequence can be turned into a-helices, ß-strands and random coils that can be printed out and folded into properly scaled…

This paper reports on a case study of two elementary school students with mathematical learning disabilities (MLD) (ages 10 and 11) using augmented reality (AR), digital and physical modelling in mathematics class. MLD students worked on modelling geometric shapes (cubes, cuboids, squared pyramids, and octahedrons) and forms (polygons) by…

Introduction: Technological advances have introduced three-dimensional (3-D) printing as an option for creating tactile maps for people with visual impairments (that is, those who are blind or have low vision), diversifying the types of map products that are available. At the same time, it presents a challenge to map makers to implement designs…

Spatial interpretation features as a skill to acquire in the educational curricula. The visualization and interpretation of three-dimensional objects in tactile devices and the possibility of digital manufacturing with 3D printers, offers an opportunity to include replicas of sculptures in teaching and, thus, facilitate the 3D interpretation of…

Additive manufacturing (3D printing) is a technology with near-unlimited potential for the chemical educator. However, its adoption into higher education has been limited by the dual requirements of expertise in 3D printing and 3D computer-aided design (CAD). Thus, its reported utilization in the chemistry curriculum has been within the creation…
