Relationships between individual development and historical change are understudied, and yet an understanding of these relationships is foundational to understanding human development. The chapter provides a case study model for investigating individual-historical relations that coordinates archival, ethnographic, interview, and experimental…

A procedure to purify anthocyanin, a natural pigment, following a green approach by using macroporous resin and its encapsulation for the maintenance of its stability is described. This laboratory experiment, which describes the benefits of using resin for the purification, is a learning tool for students working in the field on nutraceuticals.…

An efficient synthesis of the exorbitantly priced Lambert-Eaton myasthenic syndrome drug amifampridine was developed and applied in the second-semester undergraduate organic chemistry laboratory. The two-step synthesis entails a nucleophilic aromatic substitution reaction of commercial 4-chloro-3-nitropyridine with methanolic ammonia to afford…

For decades, chemical modeling sets have allowed the user to manipulate atoms and bonds using plastic/wooden ball and stick materials. Here is a design for an interlocking toy brick modeling set in which the undergraduate nursing student can manipulate electrons during the simulated chemical bonding exercise. The author presents a teaching and…

It can be a continual struggle to develop interesting and engaging experiments for use in primary schools, especially when related to electrical phenomena. Most people are familiar with the phenomenon of charged objects picking up paper or attracting hair, but there are number of simple and highly engaging activities within this area that are…

This article discusses and elaborates on how concept mapping as a specific instructional strategy helps students to externalize and transform their understanding of qualitative research; and helps instructors to focus on their students' conceptual understanding of qualitative research. The discussion focuses on concept mapping as a learning…

Scientific misconceptions are ubiquitous, and in our era of near-instant information exchange, this can be problematic for both public health and the public understanding of scientific topics. Refutation text is one instructional tool for addressing misconceptions and is simple to implement at little cost. We conducted a random-effects…

This study focuses on the relationship between students' use of language resources and their conceptualisation of phenomena in producing scientific explanations in physics. The objectives are to find out if there is a general model that describe the meaning-making process, the extent that this model is applicable to various branches in physics.…

This viewpoint proposes eight anatomy threshold concepts related to physical therapist education, considering both movement system theory and anatomical competence. Movement system theory provides classifications and terminology that succinctly identifies and describes physical therapy practice from a theoretical and philosophical framework. The…

Understanding the intricate quantifier relations in the formal definitions of both convergence and continuity is highly relevant for students to use these definitions for mathematical reasoning. However, there has been limited research about how students relearn previous school mathematics for understanding multiply quantified statements. This…

We are interested in understanding how university students learn to use programming as a tool for "authentic" mathematical investigations (i.e., similar to how some mathematicians use programming in their research work). The theoretical perspective of the instrumental approach offers a way of interpreting this learning in terms of…

The question of how the processes around the Faraday generator with its rotating magnet should be interpreted has been controversial since its discovery by Faraday. Does the magnetic field rotate together with the rotating magnet or does it remain stationary? Furthermore, does one only need Faraday's flux law to interpret inductive processes, or…

Background: Situated cognition theory suggests that representations of concepts are products of the environment wherein we learn and apply concepts. This research builds on situated cognition by investigating how concepts are tangible to a professional engineering environment. Purpose/Hypothesis: The tangibility of concepts in relation to social…

A loop-the-loop experiment is described to show how sliding friction affects motion of the ball. Conservation of energy can be used to explain the basic physics, but significant energy loss is observed in practice and expands the usefulness of this apparatus as a teaching tool.

The problem of an electrically charged pendulum above a grounded conducting surface is examined using traditional analyses, such as forces, energy, and torque. The system was numerically modelled using a finite difference method and analysed. A number of classroom activities have been suggested.
