Aragón, Acevedo-Díaz and García-Carmona study prospective biology teachers' understanding of the Nature of Science (NOS). In my comment, I would first like to step back and ask "what it is to understand something", i.e. the sciences. I will turn to a quasi-Wittgensteinian epistemological tradition and suggest that, contrary to our habit…

Zoltán Kodály, a Hungarian composer, ethnomusicologist, and music educator, is widely known for his philosophical and pedagogical contributions to music education. The purpose of this article was to trace the development of the Kodály movement in the United States from its implementation in the 1960s to present day. Questions that guided the…

Background: Cognitive communication difficulties are a characteristic feature of dementia. These deficits have negative effects on all aspects of daily life. Yet, there are few options for standardized assessment of cognitive communication skills in people with dementia. Aims: To review published cognitive-communication assessments to determine…

The guiding question of this article is to what extent, if any, Chikuro Hiroike's (1866-1938) tenets about so-called ortholinons (as moral exemplars), in his general system of moralogy, illuminate problems typically attributed to moral-exemplar methodology and help with their amelioration. I begin with a brief rehearsal of the method of using…

This study focusses on how peak performance lived experiences (identified as spiritual) during a dance career continued into and influenced the later teaching lives of former ballet dancers. The study is located in academic discussion of Western mystical and spiritual experiences. Five professional ballet teachers, who were formerly professional…

Courses: Public Speaking, Rhetorical Criticism, Persuasion, Political Communication, and Media Communication. Objectives: By the end of this activity, students should be able to: explain the key components of Lloyd Bitzer's rhetorical situation; assess and navigate various conditions affecting various speaking situations; conduct audience analysis…

An experiment for the calculation of the degree of double bond conversion, after a polymerization reaction, of photopolymerizable liquid monomers using FTIR-ATR spectroscopy is reported. The experiment was successfully conducted with undergraduate students in materials engineering during the Fundamentals of Polymeric Material course. Students…

Test score users often demand the reporting of subscores due to their potential diagnostic, remedial, and instructional benefits. Therefore, there is substantial pressure on testing programs to report subscores. However, professional standards require that subscores have to satisfy minimum quality standards before they can be reported. In this…

This article introduces the Quality of Item Pool (QIP) Index, a novel approach to quantifying the adequacy of an item pool of a computerized adaptive test for a given set of test specifications and examinee population. This index ranges from 0 to 1, with values close to 1 indicating the item pool presents optimum items to examinees throughout the…

This paper reports a systematic literature review of the balance model, an often-used aid to teach linear equations. The purpose of the review was to report "why" such a model is used, "what" types of models are used, and "when" they are used. In total, 34 peer-reviewed journal articles were analyzed, resulting in a…

Polymer chemistry lab experiments present a unique opportunity to allow students to experience the consequences of reaction mechanisms on the properties of the resulting product. In this organic chemistry experiment, students prepared a polyamide by three different reaction mechanisms that represent step-growth and chain-growth methods of…

This paper presents the results of a literature review focusing on the use and potential of Fermi problems (FPs) in the STEM disciplines. We identify different usages and roles given to FPs in each of the STEM disciplines and highlight their potential to promote modeling of real phenomena and situations as well as learning about the estimation of…

Energy is an important crosscutting concept in all science disciplines, and energy conservation is widely regarded as one of the most important principles in physics. Over the years, numerous graphical representations have been proposed that allow learners of physics to visualize energy states and dynamics in a particular situation. Each diagram…

The sensation of weightlessness is common to an astronaut in a spaceship orbiting Earth and to a person aboard a freely falling elevator. This paper presents a detailed treatment of this commonality by showing that a spaceship orbiting Earth is in permanent free fall toward the planet, appropriate for use in the introductory classroom.

A necessary skill that underpins all professional practice is noticing that which is salient. Noticing can be learned directly and indirectly through a variety of campus-based and placement activities. This paper suggests that developing a capacity for noticing is under conceptualised and underdeveloped in courses preparing students for the…
