You Need More Organization Bro: Relationship Building in Secondary Writing and Revision     

Christina Saidy  Jessica Singer Early 《Clearing house (Menasha, Wis.)》2016,89(2):54-60

In this article, we describe the peer-response workshop we conducted in an ethnically and linguistically diverse secondary school classroom in an urban center in the southwest. We show how the three main parts of the workshop combine to help students cultivate writing relationships in which they see writing as social and co-constructed, rather than as a solitary act performed for the teacher.  相似文献   

Managing the delicate matter of advice giving: accomplishing communicative space in Critical Participatory Action Research     

Christina Davidson  Christine Edwards-Groves 《Educational Action Research》2020,28(2):275-292

ABSTRACT

Critical Participatory Action Research (CPAR) requires communicative space to develop shared understandings and decisions. We examine the interactional accomplishment of such a space between a classroom practitioner and an academic researcher when meeting to reflect on a lesson and agree on future action to bring about change in the practitioner’s classroom practice. Conversation analysis of an audio recording of the meeting establishes how advice giving emerged and was managed as a delicate matter that required achieving shared understandings of what actually happened in the lesson, what could have happened, and what should happen in future lessons. Findings provide insights into how participants used reported and hypothetical speech to manage advice and reach agreement, produce and maintain intersubjectivity through interaction, and address epistemic asymmetry related to the differing experiences and roles that they brought to the action research study. Overall, the article contributes understandings of the ways that interactions produce communicative space in CPAR.  相似文献   

Combinations of Epoch Durations and Cut-Points to Estimate Sedentary Time and Physical Activity Among Adolescents     

Andreas Fröberg  Christina Berg  Christel Larsson  Cecilia Boldemann  Anders Raustorp 《Measurement in physical education and exercise science》2017,21(3):154-160

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended.  相似文献

Pulmonary monoclonal antibody delivery via a portable microfluidic nebulization platform     

Christina Cortez-Jugo  Aisha Qi  Anushi Rajapaksa  James R. Friend  Leslie Y. Yeo 《Biomicrofluidics》2015,9(5)

Nebulizers have considerable advantages over conventional inhalers for pulmonary drug administration, particularly because they do not require coordinated breath actuation to generate and deliver the aerosols. Nevertheless, besides being less amenable to miniaturization and hence portability, some nebulizers are prone to denature macromolecular drugs due to the large forces generated during aerosolization. Here, we demonstrate a novel portable acoustomicrofluidic device capable of nebulizing epidermal growth factor receptor (EGFR) monoclonal antibodies into a fine aerosol mist with a mass median aerodynamic diameter of approximately 1.1 μm, optimal for deep lung deposition via inhalation. The nebulized monoclonal antibodies were tested for their stability, immunoactivity, and pharmacological properties, which confirmed that nebulization did not cause significant degradation of the antibody. In particular, flow cytometry demonstrated that the antigen binding capability of the antibody is retained and able to reduce phosphorylation in cells overexpressing the EGFR, indicating that the aerosols generated by the device were loaded with stable and active monoclonal antibodies. The delivery of antibodies via inhalation, particularly for the treatment of lung cancer, is thus expected to enhance the efficacy of this protein therapeutic by increasing the local concentration where they are needed.  相似文献

The Impact of a Pedagogy of Teacher Education Seminar on Educator and Future Teacher Educator Identities     

Brandon M. Butler  Elizabeth Burns  Christina Frierman  Katrice Hawthorne  Alisa Innes  James A. Parrott 《Studying Teacher Education》2014,10(3):255-274

Educators require support as they move from classroom to higher education settings. This collaborative self-study provides insight into one such support space, a doctoral seminar titled Pedagogy of Teacher Education, and how our identities as educators and future teacher educators developed through participation in the course. Several important themes emerged as we negotiated and adopted new identities as educators, and future teacher educators and researchers. These themes include our development of a collaborative mindset, a teacher educator-researcher perspective, and a critical self-awareness. The findings draw on our professional and personal histories to explore the prominent features that influenced and shaped our identities as educators and future teacher educator-researchers. In sharing our development as educators and future teacher educators, this article provides insights into the ways in which doctoral students in education begin to develop their identities and pedagogies through guided support from more experienced teacher educators.  相似文献   

Protective Factors for School Readiness Among Children in Poverty     

Matthew R. Holliday  Adriana Cimetta  Christina A. Cutshaw  David Yaden  Ronald W. Marx 《Journal of Education for Students Placed at Risk》2014,19(3-4):125-147

The economic status of families and their children's learning outcomes are closely related. For example, children living in poverty tend to score worse on measures of reading and math performance than their more affluent peers, and this achievement gap is present by kindergarten. In this study, we identified protective factors associated with school readiness among an Arizona sample of children living at or below the federal poverty line (N = 230). Using multiple linear regression, we examined the association between assessments of school readiness, health status, childcare hours, home language, parent engagement, and parent education. We found that increased weekly childcare hours and better health were associated with higher proficiency in math, literacy, and approaches to learning, and may serve as resilience factors for children in poverty that may contribute to closing the achievement gap.  相似文献   

The state of evidence for social and emotional learning: A contemporary meta-analysis of universal school-based SEL interventions     

Christina Cipriano  Michael J. Strambler  Lauren H. Naples  Cheyeon Ha  Megan Kirk  Miranda Wood  Kaveri Sehgal  Almut K. Zieher  Abigail Eveleigh  Michael McCarthy  Melissa Funaro  Annett Ponnock  Jason C. Chow  Joseph Durlak 《Child development》2023,94(5):1181-1204

This article provides a systematic review and meta-analysis of the current evidence for universal school-based (USB) social and emotional learning (SEL) interventions for students in kindergarten through 12th grade available from 2008 through 2020. The sample includes 424 studies from 53 countries, reflecting 252 discrete USB SEL interventions, involving 575,361 students. Results endorsed that, compared to control conditions, students who participate in USB SEL interventions experienced significantly improved skills, attitudes, behaviors, school climate and safety, peer relationships, school functioning, and academic achievement. Significant heterogeneity in USB SEL content, intervention features, context, and implementation quality moderated student experiences and outcomes. Strengths and limitations of this evidence and implications for future USB SEL research, policy, and practice are discussed.  相似文献
