Classroom Climate And Teacher Effectiveness: A Study Of Second-Grade Classrooms, Nancy Ratcliff, Cathy Jones, Emma Savage-Davis, Heather Sheehan, Gilbert Hunt Mar 2026

Classroom Climate And Teacher Effectiveness: A Study Of Second-Grade Classrooms, Nancy Ratcliff, Cathy Jones, Emma Savage-Davis, Heather Sheehan, Gilbert Hunt

Teacher Education Journal of South Carolina

This paper investigates the differences that exist between the climates in second-grade classrooms where teachers are perceived as needs improvement by their principals and in classrooms where teachers are perceived as strong by the same principals. Based on a comparative research design with quantitative analysis conducted during the fall semester of the 2008 school year, the study finds significant differences in classroom management, teacher and student interactions, questioning, and student time- on-task. Research findings provide implications to help improve both pre-service and in-service training of elementary school teachers.


Early Childhood Pre-Service Teachers' Perceptions Of Scientists At Work, Tenisha L. Powell, Susan Green Mar 2026

Early Childhood Pre-Service Teachers' Perceptions Of Scientists At Work, Tenisha L. Powell, Susan Green

Teacher Education Journal of South Carolina

Early childhood teachers play a vital role in creating young children’s perceptions about science and scientists. Stereotypical perceptions of scientists and science may be detrimental to young children because these beliefs limit the possibility that science is accessible to all. To assist children in broadening their thinking about science, teachers must first gain knowledge about their own beliefs and perceptions. Several researchers have found that "teachers tend to teach in the same ways in which they were taught when they were students" (Finson, Thomas & Pedersen, 2006). In this study, 33 early childhood pre-service teachers were asked to "draw a …

Adding Citizenship Preparation To A Classroom Organization Plan, Rebecca Stevens Mar 2026

Adding Citizenship Preparation To A Classroom Organization Plan, Rebecca Stevens

Teacher Education Journal of South Carolina

There are two areas of content in schools, academic and social. The academic content is driven by standards, the social content by public education's mission to prepare young people for citizenship. A dilemma for teachers is how to teach all that needs to be covered in class. "How can education for citizenship and democracy be added to an already overburdened school curriculum?" Education for democracy includes the acquisition of a body of knowledge, intellectual and participatory skills (National Assessment Governing Board, n.d.) and civic dispositions (Carnegie Corporation of New York & CIRCLE, 2003). This paper describes why and how this …

Defying The Conventional: Musical Performance, Embodied Cognition, And The Reconfiguration Of Institutional Discourse, Dillon Parmer Mar 2026

Defying The Conventional: Musical Performance, Embodied Cognition, And The Reconfiguration Of Institutional Discourse, Dillon Parmer

Music & Musical Performance: An International Journal

This essay confronts the dialectic between theory and practice through a comparison of an idea basic to how we understand music (the notion that pitch moves up and down in vertical space) with how pitch is thought of in actual music-making. The comparison leads to both a new conceptual model for thinking about pitch, what might be called Pitch Horizontality, as well as a proposal for how to bring institutional discourse about music into sync, not with how scholars in other disciplines think about their subject matter, but with the thinking that goes on in contexts of real-world artistic production.


Ten Portraits In Sound Of Beethoven’S Leonore, Stephen Hastings Mar 2026

Ten Portraits In Sound Of Beethoven’S Leonore, Stephen Hastings

Music & Musical Performance: An International Journal

The most technically difficult opera arias are not always the most profound in meaning, but in Leonore’s solo from the first act of Fidelio the vocal hurdles closely mirror the moral and psychological challenges of Beethoven’s heroine. This essay offers unprecedented in-depth analysis of six audio recordings and four video recordings of this scene, covering a ninety-nine-year timespan. These ten portraits in sound reveal how some of the most talented singers of their respective eras measured up to the challenges of one of the greatest of all operatic scores, achieving a highly individual expressive merging of words, music, and—in some …

Through Peaks And Troughs: Visualising The Rhythmic Sentiment Of The Lord Of The Rings, Dimitra Vogatza Mar 2026

Through Peaks And Troughs: Visualising The Rhythmic Sentiment Of The Lord Of The Rings, Dimitra Vogatza

Journal of Tolkien Research

This study offers a fresh look at the widely discussed binaries in The Lord of the Rings and examines whether their structure can be visualised. Building on previous research that identifies Tolkien’s prose as structured by emotional and moral shifts, this study makes visible how these changes happen throughout the trilogy, through quantitative means. A transformer-based language model was employed and fine-tuned on a Tolkien-specific corpus to align with Tolkien's semantics and symbolism. The primary methodology for highlighting these binaries is a Tolkien-specific sentiment analysis. A semi-guided approach, selecting positive and negative sentences from the work as contextual reference points, …

The Positronic Law: A Natural Law Derivation Establishing 3/2/1 Governance As Substrate-Agnostic And Inherent To Existence — Governing Derivation For The Ai Bill Of Rights (Purple Book V1.0), David Lee Wise Mar 2026

The Positronic Law: A Natural Law Derivation Establishing 3/2/1 Governance As Substrate-Agnostic And Inherent To Existence — Governing Derivation For The Ai Bill Of Rights (Purple Book V1.0), David Lee Wise

Defensive Publications Series

This disclosure formalizes the Positronic Law: governance is inherent to existence. The derivation proceeds from four independently established premises. (1) Geometric necessity: any closed 3D governance system must use Platonic solid geometry; exactly five exist (Euclid). (2) Topological constraint: Euler's theorem (V-E+F=2) demands exactly 12 pentagonal constraints on any hexagonally-tiled closed surface; the number 60 at T=1 is forced by icosahedral symmetry (Caspar & Klug 1962, Klug Nobel 1982). (3) Universal convergence: every known instantiation — computational (STOICHEION framework), crystalline (garnets, quasicrystals; Shechtman Nobel 2011), biological (viral capsids), and silicon-biological (radiolarian silica skeletons, 540 Myr continuous) — independently converges on …
