The laboratory experiment presented here describes the use of a calcium ion-selective electrode (Ca-ISE) to determine the concentration of zinc in a supplement tablet. This approach was developed to show students how to expand the range of applications of Ca-ISE to enable the determination of metal ions other than Ca[superscript 2+]. To determine…

Although biochemistry is fascinating to undergraduates regardless of their major, the complexity involved requires a great deal of effort and leads many to perceive it to be an intense, facts-based course limiting personal creativity. This activity takes the fundamental knowledge associated with inducible promoters and combines it with the…

The presented study examines the question of colour categorization in relation to the hypothesis of linguistic relativity. The study is based on research conducted by Gilbert et al. (2006) and their claim that linguistic colour categorization in a particular language helps colour recognition and speeds the process of colour discrimination for…

Business cases are commonly adopted into the accounting curricula to promote deep learning. However, in practice, case-based learning is often ineffective without facilitation because of accounting students' strong surface-learning tendencies. This study investigates the case-based learning effect of colour-coded digital annotation (CCDA). CCDA…

The cognitive advantage (CA) hypothesis claims that multilingualism promotes the development of several basic cognitive capacities. A large number of empirical findings support this hypothesis, but recently there have also been numerous contradictory findings and methodological objections. The present paper extends the investigation of possible…

Stimulating interest in science at an early age is important for STEM education. This work details an educational activity utilizing the anthocyanins found in butterfly pea flowers ("Clitoria ternatea"). This activity was developed for use in official classroom settings, online, and/or at-home with parental or educator guidance. Primary…

This study explores teachers' perspectives on mandala coloring as a therapeutic tool for middle grades students with disruptive behavior disorders (DBDs). Employing an explanatory sequential mixed-methods design, the research first conducted qualitative interviews with ten experienced teachers, followed by teachers' quantitative assessments of 60…

Purpose: This study aims to understand the perception of young people regarding different communication strategies to promote proenvironmental disposal behavior. Based on the attention-interest-desire-action (AIDA) model, the study analyses how university students react to different communication approaches used by a university aiming at the…

When asked to identify objects having unique shapes and colors among other objects, English speakers often produce redundant color modifiers ("the red circle") while Spanish speakers produce them less often ("el circulo (rojo)"). This cross-linguistic difference has been attributed to a difference in word order between the two…

Water pollution has been one of the major issues of the present time. It is essential to educate students regarding this issue and its possible solutions. In this article, a demonstration of a typical adsorption-based water cleaning process is presented. The removal of methylene blue (MB) and detergent from an aqueous solution is demonstrated…

Children begin to emulate writing and what they see around them at a very early age (Byington & Kim, 2017). The simple scribbles they begin to produce are representations of complex cognitive processes occurring. The constant cognitive scaffolding which medical students experience can be compared to the cognitive process children participate…

Synthesis and diffusion of a pigment molecule can be simulated using deterministic equations in computer software. These lesson materials describe how tiger stripes emerge from manipulations in this code, and how students can engage in mathematical inquiry by exploring these reaction-diffusion equations.

Dividing attention (DA) between a memory task and a secondary task results in deficits in memory performance across a wide array of memory tasks, but these effects are larger when DA occurs at encoding than at retrieval. Although some research suggests the effects of DA are equal for item and associative memory, thereby suggesting that DA disrupts…

Working memory (WM) improves dramatically during childhood but what drives this improvement is not well understood. One influential account thus far has proposed a simple increase in storage capacity. However, recent findings have shown that multiple factors, such as differences in the ability to use attention to enhance the maintenance of…

A personal annotation is a rich object with an important cognitive facet. In the e-Learning context, learners' annotation can contain important emotional features. These features can be used to recognize the learner's emotional state during the learning session; very important feedback that has been lost in e-Learning mode in comparison to…
