The article describes research work that can help students observe and experimentally research the effects caused by the emission component of the filament current in fluorescent lamps' cathodes. When analysing the work of electronic devices--multi-purpose lamps that use thermionic emission--research usually focuses on the current caused by the…

Wide accessibility and a broad range of applications have made 3D-printers a commonplace tool in the science community. From tier-one research institutions to community public libraries and high schools, 3D-printers are being used to enrich STEM education through a variety of learning techniques and experiences. Reports of 3D-printed models for…

Improvisation is a fundamental aspect of musicianship and an important pursuit in music education. Children in music classes throughout the world are engaged with improvisation in a variety of modes and settings. Whether singing, physically moving, or playing an instrument, the act of improvising in front of others may raise one's…

Recently, Christopher C. Tisdell questions some claims and results that appear in our article [Rivera-Figueroa A, Rivera-Rebolledo JM. A new method to solve the second-order linear difference equations with constant coefficients. Int J Math Educ Sci Technol. 2016;47(4):636-649.] regarding the novelty and simplicity of a method to solve…

A method is described to measure the coefficient of restitution (COR) by dropping a ball on a piezoelectric disk. Multiple bounces can be observed at small drop heights, so the average COR over say ten bounces can be obtained from just one ball drop, without having to measure the bounce height or the bounce speed. The results show directly that…

Historically assessing deaf and hard of hearing (D/HH) students has been a daunting challenge. Although significant strides have been made, there continues to be a dearth of research and literature specifically addressing the endemic challenges multidisciplinary teams encounter when assessing D/HH students. This article delineates a historical…

This study examines the key concepts of elements-and-principles art instruction, as defined in the publications by "Vorkurs" (preliminary course) instructors at the Bauhaus. Elements-and-principles instruction was for decades central to formalist art training, and continues to play a role, albeit limited, today. Preceding accounts of the…

Sir Ronald Fisher's venerable experiment "The Lady Tasting Tea" is revisited from a Bayesian perspective. We demonstrate how a similar tasting experiment, conducted in a classroom setting, can familiarize students with several key concepts of Bayesian inference, such as the prior distribution, the posterior distribution, the Bayes…

Evidence of the internal consistency of standard-setting judgments is a critical part of the validity argument for tests used to make classification decisions. The bookmark standard-setting procedure is a popular approach to establishing performance standards, but there is relatively little research that reflects on the internal consistency of the…

One commonly used compromise standard-setting method is the Beuk (1984) method. A key assumption of the Beuk method is that the emphasis given to the pass rate and the percent correct ratings should be proportional to the extent that the panelists agree on their ratings. However, whether the slope of Beuk line reflects the emphasis that panelists…

The purpose of this study was to compare 12 commonly-used nonoverlap methods with each other and with the results of visual analysis. Data were obtained from 25 studies focused on embedded instruction and schema-based instruction and included a total of 101 graphs. Treatment effect estimates using 12 nonoverlap methods were calculated for each…

Due to increase in complexity of modelling human behaviour in virtual environment, traditional or conventional didactic learning is limited in providing flexible or dynamic e-learning environment to students. Adaption of e-learning content with respect to several e-learning problems is open research problem in front of all of us. The purpose of…

Dialogic teaching has enormous potential to harness the power of talk in developing children's thinking but is sometimes challenging to enact within today's policy context. Similarly, sustained shared thinking is an established and powerful practice with children in the early years but faces pressure within today's educational climate. Though…

Love, beauty, and the good are three key concepts of Platonic aesthetics, which frequently appear in the fairy tales of Oscar Wilde, a classical scholar deeply influenced by Plato and his philosophy. Plato's views on music, as a part of his aesthetics, were championed by Wilde, who regarded music as "the perfect type of art." It is…

In the modern, information driven society managing and handling data is unavoidable. The most common form of data handling is to organize data into tables and complete operations on them in spreadsheets. Sprego (Spreadsheet Lego) is a programming-oriented methodology focusing on schemata construction and authentic problem-solving working with only…
