What Makes Classroom Observation Feedback Useful? The Perceptions Of Secondary Math And English Teachers, Amanda Frasier

ETSU Faculty Works

Teachers (n=14) at four high schools in North Carolina were interviewed about their perspectives of evaluation policy at two time points during the 2016-2017 school year. This study specifically examined statements teachers made about feedback from observations using de-identified interview transcripts. Teachers discussed feedback from formal observations along with other sources of informal observational feedback (e.g., coaches, peers). Overall, teachers described useful feedback as that which provided actionable recommendations informed by the observer’s knowledge of three domains: the classroom context (as aided by the frequency and timing of observations), subject area, and pedagogy. Teachers also identified two aspects of formal …

Establishment Of An In Vivo Streptozotocin-Induced Type 1 Diabetes Model Recapitulating Early Brain And Retinal Fibrosis, Kia Bourdot, Lucy Dawson, Igor Kuzin, Arturo Bravo Nuevo, Zeus Antonello

Cooper Rowan Medical Journal

INTRODUCTION: Diabetes has risen to one of the top American public health concerns. The hyperglycemic state of chronic diabetes leads to microvascular and macrovascular changes that predispose patients to delayed wound healing and organ fibrosis. The validation of models to specifically detect early, quantifiable fibrotic changes seen in the diabetic state is of fundamental importance for understanding the diabetic pathophysiology and exploring earlier management options. Here, we investigated if we could detect early signs of internal fibrosis in a streptozotocin (STZ) diabetic mouse model by quantifying α-SMA expression in various organs using flow cytometry.

Lithium-ion batteries (LIBs) have become one of the best solutions to the energy storage issue in modern society. However, the battery materials and device development are both complex, and involve multivariable problems. Traditional trial-and-error approach, which relies on researchers to conduct experiments, has encountered bottlenecks in the improvement of the battery performance. Artificial intelligence (AI) is the most potential technology to deal with this issue due to its powerful high-speed and capabilities of processing massive data. In particular, the capability of machine learning (ML) algorithms in assessing multidimensional data variables and discovering patterns in the sets are expected to assist …

The Sexual And Gender-Based Violence Epidemic Meets The Covid-19 Pandemic: Survivors’ And Advocates’ Narratives In Egypt, Mozn Hassan, Helen Rizzo

Faculty Journal Articles

This research traces activism over the last 30 years against sexual and gender-based violence with a focus on survivors’ and advocates’ narratives in Egypt. We argue that several focusing events in Egypt and the support of transnational advocacy networks over the last decades have galvanised the efforts of activists and citizens of good will to mobilise around these issues. Egyptian feminist mobilisation during the pandemic brought to the public sphere the untold stories of the forms of violence that occurred through online and social media platforms.

Decadal Time-Series Depletion Of Dissolved Oxygen At Abyssal Depths In The Northeast Pacific, K. L. Smith, M. Messié, T. P. Connolly, C. L. Huffard

Faculty Research, Scholarly, and Creative Activity

Dissolved oxygen depletion in the global ocean is well documented over several decades from the surface ocean to abyssal depths. This decline is especially prevalent in the Northeast Pacific. A significant decline in dissolved oxygen has been measured over 30 years at 4,000–4,100 m depth (Station M) beneath the California Current off central California. Three principal hypotheses examined the relationship of declining oxygen with biological and physical factors over the 30-year time series. Annual resolution revealed Ekman pumping, coastal upwelling, particulate matter flux, and sediment community oxygen consumption having significant correlations with bottom water dissolved oxygen concentration. Coastal upwelling accounted …
