Exploring the Impact of Language Modeling Integration in Classroom Assessment Scoring System (Class) on Language Teaching and Learning in Pre-K Settings: A Comprehensive Analysis of Teacher-Child Relationships and Interactions
Get PDFThis descriptive research study utilizes a mixed methods design to explore the impact of integrating language modeling into the Classroom Assessment Scoring System (CLASS) on teachers\u27 perspectives on language teaching and learning. Additionally, the study analyzed teacher-child interactions in Pre-K settings in Southeast Virginia, U.S.A.
Observations were conducted in eleven (11) classrooms using the Pre-K CLASS, a key instrument for assessing the quality of teacher-child interactions across domains such as Emotional Support, Classroom Organization, and Instructional Support, which includes Language Modeling. The CLASS tool was supplemented with detailed notetaking to capture both quantitative scores and qualitative nuances of interactions. This approach provided objective data crucial for addressing Research Question 1 (RQ1) - How do Pre-K teachers perceive, integrate, and describe the impacts of teaching with language modeling on their children’s learning? and Research Question 2 (RQ2) - How do teacher-child relationships and interactions contribute to the support of language development and language learning in Pre-K classrooms? It facilitated a comprehensive analysis through bivariate correlations, regression results and performance characteristics, concentrating on the crucial elements that contribute to effective language development in early childhood education.
Following the observations, eleven (11) participating Pre-K teachers took part in one-on-one structured interviews and a collaborative focus group session. These qualitative methods aligned with the research questions and theoretical framework, encouraging teachers to share their experiences with language modeling, its perceived impact, and their feelings about language-related classroom activities. The focus group facilitated collaborative discussions, allowing a shared exploration of language modeling practices. These in-depth conversations captured the qualitative aspects of integrating language modeling, emphasizing the multifaceted nature of teachers’ experiences.
The findings emphasize the importance of adapting to diverse needs, overcoming challenges, and engaging in continuous professional development to maintain effective teaching practices. Colleagues\u27 collaborative approach and consistent refinement of strategies contribute to creating an inclusive and supportive learning environment that fosters language growth and development
Wind Tunnel Automation For Propeller Testing
Get PDFAn automated propeller test capability for the ODU Low-Speed Wind Tunnel Facility is demonstrated; implementing automation improved both ease of testing and quality of results. An experiment was performed with and without automation to compare results. Prior to this effort, propeller RPM and airstream velocity were manually controlled, leading to time consuming experiments. The setpoint for RPM had to be adjusted at each run to compensate for changes in airstream velocity.
LabVIEW, a graphical programming software, was used to develop the controllers and automation algorithm. A Proportional Integral Derivative (PID) control approach was developed to simultaneously control airstream velocity and propeller RPM. An automation algorithm was also developed to perform a series of runs, leveraging the PID controllers to minimize the need for user input. The algorithm supported general serial testing, and Design of Experiment (DOE) -based design approaches.
The comparison between manual and automated experiments followed the same restricted randomization experimental design developed in statistical design software; both experiments used identical set points and identical tools were used to simplify the regression model.
The automated experiment provided more precise results, resulting in a higher order model than the manual experiment. The measured advance ratios for the automated experiment deviated less from the nominal values than the manual experiment. Furthermore, the majority of verification runs on the automated experiment fell within the prediction interval whereas most responses on the manual experiment did not
The Impact of Peer Observational Learning on Honesty Following a Transgression
Get PDFParents and teachers worry about how lying affects children\u27s development and socialization, as research links persistent lying to delinquency, aggression, and conduct issues. To investigate this, we examined two groups: Honest and Praise versus a Control Group, exploring how exposure influenced children\u27s honesty and confession after transgressions. The study aimed to see if observing peers receive praise for honesty could promote truthfulness. Gender\u27s impact on reporting honesty was assessed. Results showed no significant difference in honesty between the HP and CG groups; children confessed at similar rates in both conditions. Gender did not affect honest reporting. These findings differ from previous research in this area and suggest that factors beyond praise might be more influential in fostering honesty in children
Flavor Dependence of Charged Pion Fragmentation Functions
Get PDFWe have measured the flavor dependence of multiplicities for π+ and π− production in semi-inclusive deep-inelastic scattering (SIDIS) on proton and deuteron to explore a possible charge symmetry violation in fragmentation functions. The experiment used an electron beam with energies of 10.2 and 10.6 GeV at Jefferson Lab and the Hall-C spectrometers. The electron kinematics spanned the range 0.3 \u3c x \u3c 0.6, 2 \u3c Q² \u3c 5.5 GeV², and 2.2 \u3c W \u3c 3.2 GeV. The pion fractional momentum range was 0.3 \u3c z \u3c 0.7, and the transverse momentum range was 0 \u3c pT \u3c 0.25 GeV/c. Assuming factorization and allowing for isospin breaking, the results can be described by two “favored” and two “unfavored” effective low pT fragmentation functions that are flavor-dependent. We find each pair converges to a common flavor-independent fragmentation function at the highest W, where factorization is most applicable
Effects of High Temperature Compaction on 3D Printed Carbon Fiber Reinforced Polymer Composites
Get PDFThe aim of this dissertation was to study the effects of hot temperature compaction (HTC) upon the polymorphism and the mechanical behavior of an additively manufactured (AM), carbon fiber reinforced polyamide (PA6). Different pressure and temperature levels during HTC were tested to determine the overall effect upon the mechanical behavior and the material crystalline composition. Treated, carbon fiber reinforced PA6 samples were analyzed using differential scanning calorimetry, x-ray diffraction, thermogravimetric analysis, scanning electron microscopy, double cantilever beam testing and three-point bending testing. When considered with respect to as-printed samples, an HTC temperature of 190°C combined with 80 psi pressure resulted in increased flexural modulus and flexural strength by 47% and 58%, respectively. This increase was attributed to the decrease of AM induced cracking, voids (both inside and between the beads), and a crystalline solid-state transition in the PA6. However, compaction also leads to embrittlement as the level of crystallinity increases. A double cantilever beam characterization demonstrated that this increase in crystallinity served to reduce the fracture toughness of the material. Therefore, HTC can help overcome some limitations of traditional annealing, which can result in increased mechanical properties. However, an increase in crystallization also leads to material embrittlement

Evaluating the Chemical Reactivity of Wildfire-Derived Dissolved Organic Molecules: Glutathione Binding Through Kendrick Mass Defect Analysis
Get PDFThe emerging risks to organisms of pyrogenic-derived dissolved organic matter (PyDOM) from forest fires are of concern due to its toxic and mutagenic potential (e.g., pro-oxidative responses in fauna through the depletion of glutathione, a nitrogen- and sulfur-containing tripeptide found in cells). This study simulates this phenomenon in a laboratory setting by identifying bonding between reduced l-glutathione and organic molecules in leachates from environmentally weathered biomass samples (charred and uncharred) using Kendrick Mass Defect (KMD) analysis from formula lists obtained from negative-mode electrospray ionization-Fourier transform-ion cyclotron resonance-mass spectrometry ((-)ESI-FT-ICR-MS). These formula lists reveal a 10-fold increase in nitrogen- and sulfur-containing molecular formulas in the charred biomass samples compared with the unreacted charred biomass when subjected to reaction with glutathione. KMD analysis attributed the bonding of glutathione to the biomass leachates accounting for approximately 25% of the new nitrogen- and sulfur-containing molecular formulas as either addition-type or condensation/elimination-type reactions. KMD sheds light on a different fraction of chemically reactive wildfire-produced organic compounds that may be of interest for subsequent toxicological studies
On Cadava and Levy\u27s \u3ci\u3eCities Without Citizens\u3c/i\u3e
No full text[First paragraph]
What, the editors of this collection ask in their introduction, is the nature of the relationship between cities and the people who inhabit them? And how do the historical situation of cities and their citizens limit the potentiality of new modes of subjectification? These are surely evocative questions, and as the editors remark, increasingly necessary ones, as the city is quickly becoming the organizing principle for global flows (of bodies, capital, law, etc.), but, in the collection that follows, the contributing authors barely scratch the surface of these issues, nor do they properly problematize such latter-day master narratives as the primacy of capitalism, globalization, warfare and the law, let alone citizenship itself. Instead this collection reads as a series of rather disconnected chapters brought together seemingly only by the force of will of the editors. That being said, a number of the chapters are provocative and insightful in their various critiques, however far from the site of the city and the problematics of citizenship they may stray
Self-Efficacy and STEM Education: A Study of Family and Consumer Science Teachers in Pennsylvania
No full textScience, technology, engineering, and mathematics (STEM) education has become widely promoted. Family and Consumer Sciences (FCS) uses science to improve home life while reinforcing technology, engineering, and mathematics principles. However, FCS is not usually recognized as a STEM subject. The purpose of this study was to determine what factors may affect FCS teachers’ level of self-efficacy in teaching STEM to provide supports that improve teaching practices. This quantitative study surveyed secondary FCS teachers in Pennsylvania using the T‐STEM Survey for Elementary Teachers. Results were analyzed using descriptive statistics and simple linear regression analysis was performed to determine the predictive relationship between the independent variables and each of the teacher self-efficacy construct scores as the dependent variable. The first research question explored the level of self-efficacy of FCS teachers regarding teaching STEM concepts. The second research question explored how each of the teacher demographic variables respectively predicts the level of self-efficacy of FCS teachers when teaching STEM concepts. A regression analysis was used to test the differences among variables that had significant effects (significance level at p \u3c 0.05). The five independent variables were participation in FCCLA, number of STEM courses taken, education level, number of years in teaching, and gender. Overall, FCS teachers scored highest in 21st-century learning attitudes and lowest in STEM instruction. Results indicated the independent variable, number of STEM courses taken, was a significant predictor of 21st-century learning attitudes (b = .02, SE = .01, p = .019)
Fibrinolysis for Apical Thrombus as a Bridge to Emergent Valve-in-Valve Transcatheter Aortic Valve Replacement
No full textBackground
Left ventricular (LV) thrombus is traditionally a contraindication to transcatheter aortic valve replacement due to embolic risk. Consequently, management of valvular cardiogenic shock complicated by LV thrombus identifies unique challenges that require innovative strategies.
Case Summary
A 58-year-old woman with critical bioprosthetic aortic stenosis, cardiogenic shock, and large LV thrombus (2.8 × 2.6 cm) underwent successful valve-in-valve transcatheter aortic valve replacement after systemic fibrinolysis bridge therapy.
Why Beyond the Guidelines
Current guidelines contraindicate transcatheter aortic valve replacement in patients with LV thrombus. This case demonstrates the novel use of low-dose, slow infusion tissue plasminogen activator as a bridge therapy to enable life-saving intervention.
Discussion
Pulsed delivery of small doses of systemic fibrinolytic with hemodynamic and echocardiographic monitoring may be suitable as a bridge to definitive management in valvular shock patients with LV thrombus. Minimizing instrumentation during structural heart procedures complicated by LV thrombus is critical.
Take-Home Messages
Low-dose, slow-infusion fibrinolysis coupled with echocardiographic monitoring may serve as bridge therapy to urgent structural cardiology intervention in carefully selected patients with LV thrombus and cardiogenic shock
