A simple method to determine Lewis electron dot structures and formal charges without a need to sum all of the valence electrons, reorganize electron pairs, draw and pair up individual electrons, or remember a formal charge formula is described. The formal charge is determined by the group number (number of valence electrons) and the number of…

An elementary method to calculate the area, centroid and volume of rotation of the Koch curve is presented. Classroom extensions are provided to allow students to investigate the method used.

Purpose: The excised canine larynx provides an advantageous experimental framework in the study of voice physiology. In recent years, signal processing methods have been applied to analyze phonations in excised canine larynx experiments. However, phonations have a highly complex and nonstationary nature corresponding to different proportions of…

Teaching listening means more than just giving students listening activities and checking for understanding--it means teaching them how to listen. "Listening in the Classroom" takes promising research findings and theory and turns them into practical teaching ideas that help develop listening proficiency.

In the third of a series, the author describes how symmetrical quintic functions can be expressed in three equivalent formats--like other symmetrical functions. Quadratic functions have a line of symmetry through their vertex and cubic functions have 1800 rotational symmetry around their point of inflection. However, polynomial functions of degree…

Although strong claims have been made about museums being ideal word learning environments, these are yet to be empirically supported. In the current study, 152 four- to five-year-olds children (81-M, 71-F) from minority backgrounds were taught six vocabulary items either in a museum, in their classroom with museum resources, or in their classroom…

As more and more science teacher educators are subscribing to a practice-based teacher education curriculum, it is becoming increasingly necessary to identify and articulate smaller grain-sized teaching practices nested within a core practice in important instructional contexts in order to facilitate preservice science teachers' (PSTs') learning…

Anxiety problems are common in children and can have profound adverse effects on personal, social and academic life. Almost 40% of anxiety disorders emerge before age 14, making primary schools invaluable settings for prevention and early support of child anxiety. Research indicates that school-based interventions can be costly and difficult to…

The quality of mixing methods has been widely debated in the field of applied linguistics (AL) and the integration of data from both quantitative and qualitative research paradigms has always been open to controversy. The present study was aimed at recognizing the status quo of MMR in AL, investigating the nature of various sections of MMR…

Research indicates that introducing Philosophy with Children (PwC) in schools can lead to a number of desirable benefits in terms of improving academic skills in students. However, as PwC differs from dominant forms of teaching, its introduction may be challenging. To better understand these challenges and how they can be resolved, knowledge about…

In response to the national excitement around course embedded assessment, various campuses and state-wide college systems engaged in faculty development in assignment prompt development drawn from the literature focused on creating assignments for the classroom. However, while the literature is replete with frameworks, templates, guides,…

In this article, Julia So discusses the purpose of program assessment, four common missteps of program assessment and reporting, and how to prevent them. The four common missteps of program assessment and reporting she has observed are: (1) unclear or ambiguous program goals; (2) measurement error of program goals and outcomes; (3) incorrect unit…

For decades, the education system has struggled to serve Latinx students, viewing them in a way that focuses on their deficits. However, Latinx scholars have proposed a series of asset-based frameworks to reframe and reshape how we see and treat Latinx students in the U.S. system. Using the "Dora the Explorer"'s "mochila"…

Item response theory (IRT) models typically rely on a normality assumption for subject-specific latent traits, which is often unrealistic in practice. Semiparametric extensions based on Dirichlet process mixtures (DPMs) offer a more flexible representation of the unknown distribution of the latent trait. However, the use of such models in the IRT…

The role of anatomical variability in safe clinical practice is underappreciated. A lack of familiarity of anatomical variations is at the center of a multitude of medical and surgical errors. The recent rise in litigation due to such errors suggests that patient care may be compromised. This makes the knowledge of anatomical variation essential…
