Electrocardiography (ECG) is one of the most widely used methods in clinical diagnosis. Here we describe an experimental approach that offers hands-on learning of its basic principles. An experimental model that consists of a rubber foil with a low electrical conductivity and a DC power unit is used to simulate the body and the electric dipole of…

Object representations from convolutional neural network (CNN) models of computer vision (LeCun, Bengio, & Hinton, 2015) were used to drive a cognitive model of decision making, the linear ballistic accumulator (LBA) model (Brown & Heathcote, 2008), to predict errors and response times (RTs) in a novel object recognition task in humans.…

Student-generated drawings are known to be effective in building and revealing students' conceptions of chemistry. Some chemistry concepts, moreover, include changes and processes that cannot be merely represented by static drawings. Computer-based animations are needed to represent the dynamics. In this study, 25 chemistry student teachers, who…

In this article, the authors offer four specific reading comprehension strategies that mathematics teachers of all levels can employ with their students when working on word problems: (1) visualizing; (2) retelling; (3) making connections; and (4) asking questions. These strategies, which have a substantial research base in literacy, are discussed…

Creating meaningful learning environments that support university students in their early STEM courses has become a focus of interest for many universities. This research investigated an active learning environment where students used Ozobot robots to visualize complex concepts such as Metabolism, Photosynthesis and Cellular Respiration in an…

Computational thinking is the capacity of undertaking a problem-solving process in various disciplines (including STEM, i.e. science, technology, engineering and mathematics) using distinctive techniques that are typical of computer science. It is nowadays considered a fundamental skill for students and citizens, that has the potential to affect…

Recently, there has been increasing evidence showing that males estimate whole numbers more accurately than females on the number line. However, relatively little is known about what factors contribute to this gender gap. The current study explored potential mediators of the gender difference in number line estimation, including spatial skills and…

Mathematical geometrical (MG) concept is often perceived as abstract and difficult to understand by students at the TVET College. Students are unable to perform well in Mathematic Assessments Tasks specifically on this concept. Drawing from this is the declining percentages of student enrolments in mathematics at National Qualification Framework…

Caribbean nations are amongst those considered the most vulnerable to climate change impacts. This necessitates climate change education (CCE) to enhance the mitigation and adaptation capacities of the region's populace. CCE is necessary at all levels of the education system, from pre-primary through to the tertiary level. To facilitate this,…

This case study of an art education program for medical students examines the efficacy of different types of content and modes of delivery. Through the delivery of art analysis, art history, sculpting, and life drawing seminars, art educators were able to teach empathy, observation, and flexible thinking to first-year medical students. This…

The goal of undergraduate chemistry laboratories is to allow students to learn about chemical systems and key laboratory skills. They should then apply this knowledge to solve problems and connect macroscopic observations in the laboratory with those occurring at the submicroscopic level. Unfortunately, these needs are not met through traditional…

This paper explores the potential of online lesson visualization and annotation tools in fostering international lesson-centered teacher collaboration. In an era where teachers face diverse challenges and limited opportunities for peer-to-peer collaboration, leveraging digital tools for asynchronous exchanges emerges as a promising avenue for…

Molecular symmetry and orbitals are two important chemical concepts which can be difficult for students to visualize in three dimensions; as such, instructors have traditionally adopted a variety of approaches to teach them including the use of physical models and digital renderings/resources. This paper describes a new mobile device application…

The purpose of the study was to explore the effects of augmented reality (AR) in an introductory engineering graphics course. The study specifically examined the potential for AR to affect the spatial visualization ability of students and influence student motivation. This study included 50 students from an introductory engineering graphics course…

The purpose of this study is to examine the effects of different ways to use visualizations on high school students' electrochemistry conceptual understanding and motivation towards chemistry learning. Expanding upon a model-based learning approach (Khan, 2007), we adopted a VGEM sequence (View, Generate, Evaluate, and Modify) to create three…
