Five Secondary Teachers: Creating and Presenting a Teaching Persona

This qualitative study investigates the ways that five secondary teachers developed and presented personae. The researcher collected and analyzed data using a theoretical frame based in social psychology, including Goffman’s Presentation of Self in Everyday Life (1959), and Miles and Huberman’s (1994) three-step approach to qualitative data analysis. Findings indicate that teachers drew on three major realms—the physical, psychological, and social—when constructing classroom personae. Implications include increased opportunities for teacher reflection on persona and its effects

Developing and Presenting a Teaching Persona: The Tensions of Secondary Preservice Teachers

This qualitative, multiple case study investigated the ways that three preservice secondary teachers developed, presented, and considered their teaching personae. Data for each participant consisted of three interviews, field observations of both teaching and nonteaching, data collection of lessons and class documents, and four journal reflections. Findings show that the participants experienced various tensions as they formed their teaching personae; as they navigated these tensions, they drew on discourses and ideas about good teaching and their various experiences, including the practicum experience. The nature of the interactions between the Cooperating Teacher and preservice teacher pairs contributed to the preservice teachers’ confidence in and understanding of their enacted personae. Implications of the research for teacher training programs include an increased need for reflection on persona and careful matching of CIs and student teachers. Suggestions for further research include investigating the effect of high-quality teacher education programs on persona development and the effects of personae on pupils

Lessons from the Pivot: Higher Education\u27s Response to the Pandemic

The intensity of major events often leads us to remember minute details of where we were and what we were doing when they occurred: what we wore as we watched the towers fall on September 11, 2001; the faces of our classmates when the space shuttle Challenger exploded on January 28, 1986; the smell in the air when we lived through a major earthquake, fire, or other personal tragedy. Similarly, faculty, staff, and students will remember the series of moments that led to the closure of their schools and universities as the 2020 COVID-19 pandemic spread throughout the world--the timeline varies, but on the East Coast of America, this occurred in early March. Unprecedented became the word of the year in our emails and texts and Zoom calls. We adjusted our expectations; we pivoted our planning, instruction, and interactions; and we continue to do so

Lessons from the Pivot: Higher Education\u27s Response to the Pandemic

This text includes chapters from instructional designers, university faculty and staff, and undergraduate and graduate students, and the text has been divided into three sections to reflect these varied perspectives. Each section begins with research-based perspectives, but also contains more personal narratives at the end. While the context of most of the chapters is the United States, there are also chapters with a Canadian context. It is also important to note that, as of the first half of 2021, the pandemic rages on, and mentions of COVID-19 in the following chapters will be reflective of the state of affairs in North America in the spring and fall of 2020.https://scholar.umw.edu/education_books/1000/thumbnail.jp

Activity Dependent Protein Degradation Is Critical for the Formation and Stability of Fear Memory in the Amygdala

Protein degradation through the ubiquitin-proteasome system [UPS] plays a critical role in some forms of synaptic plasticity. However, its role in memory formation in the amygdala, a site critical for the formation of fear memories, currently remains unknown. Here we provide the first evidence that protein degradation through the UPS is critically engaged at amygdala synapses during memory formation and retrieval. Fear conditioning results in NMDA-dependent increases in degradation-specific polyubiquitination in the amygdala, targeting proteins involved in translational control and synaptic structure and blocking the degradation of these proteins significantly impairs long-term memory. Furthermore, retrieval of fear memory results in a second wave of NMDA-dependent polyubiquitination that targets proteins involved in translational silencing and synaptic structure and is critical for memory updating following recall. These results indicate that UPS-mediated protein degradation is a major regulator of synaptic plasticity necessary for the formation and stability of long-term memories at amygdala synapses

Latitude dictates plant diversity effects on instream decomposition

Running waters contribute substantially to global carbon fluxes through decomposition of terrestrial plant litter by aquatic microorganisms and detritivores. Diversity of this litter may influence instream decomposition globally in ways that are not yet understood. We investigated latitudinal differences in decomposition of litter mixtures of low and high functional diversity in 40 streams on 6 continents and spanning 113 degrees of latitude. Despite important variability in our dataset, we found latitudinal differences in the effect of litter functional diversity on decomposition, which we explained as evolutionary adaptations of litter-consuming detritivores to resource availability. Specifically, a balanced diet effect appears to operate at lower latitudes versus a resource concentration effect at higher latitudes. The latitudinal pattern indicates that loss of plant functional diversity will have different consequences on carbon fluxes across the globe, with greater repercussions likely at low latitudes

Generic health literacy measurement instruments for children and adolescents:a systematic review of the literature

Background Health literacy is an important health promotion concern and recently children and adolescents have been the focus of increased academic attention. To assess the health literacy of this population, researchers have been focussing on developing instruments to measure their health literacy. Compared to the wider availability of instruments for adults, only a few tools are known for younger age groups. The objective of this study is to systematically review the field of generic child and adolescent health literacy measurement instruments that are currently available. Method A systematic literature search was undertaken in five databases (PubMed, CINAHL, PsycNET, ERIC, and FIS) on articles published between January 1990 and July 2015, addressing children and adolescents ?18 years old. Eligible articles were analysed, data was extracted, and synthesised according to review objectives. Results Fifteen generic health literacy measurement instruments for children and adolescents were identified. All, except two, are self-administered instruments. Seven are objective measures (performance-based tests), seven are subjective measures (self-reporting), and one uses a mixed-method measurement. Most instruments applied a broad and multidimensional understanding of health literacy. The instruments were developed in eight different countries, with most tools originating in the United States (n =?6). Among the instruments, 31 different components related to health literacy were identified. Accordingly, the studies exhibit a variety of implicit or explicit conceptual and operational definitions, and most instruments have been used in schools and other educational contexts. While the youngest age group studied was 7-year-old children within a parent-child study, there is only one instrument specifically designed for primary school children and none for early years. Conclusions Despite the reported paucity of health literacy research involving children and adolescents, an unexpected number of health literacy measurement studies in children?s populations was found. Most instruments tend to measure their own specific understanding of health literacy and not all provide sufficient conceptual information. To advance health literacy instruments, a much more standardised approach is necessary including improved reporting on the development and validation processes. Further research is required to improve health literacy instruments for children and adolescents and to provide knowledge to inform effective interventionspublishersversionPeer reviewe
