The Right “Fit”: Exploring Science Teacher Candidates’ Approaches to Natural Selection Within a Clinical Simulation     

Benjamin Dotger  Sharon Dotger  Joanna Masingila  Jeffrey Rozelle  Mary Bearkland  Ashley Binnert 《Research in Science Education》2018,48(3):637-661

Teachers and students struggle with the complexities surrounding the evolution of species and the process of natural selection. This article examines how science teacher candidates (STCs) engage in a clinical simulation that foregrounds two common challenges associated with natural selection—students’ understanding of “survival of the fittest” and the variation of species over time. We outline the medical education pedagogy of clinical simulations and its recent diffusion to teacher education. Then, we outline the study that situates each STC in a one-to-one interaction with a standardized student who is struggling to accurately interpret natural selection concepts. In simulation with the standardized student, each STC is challenged to recognize content misconceptions and respond with appropriate instructional strategies and accurate explanations. Findings and implications center on the STCs’ instructional practices in the simulation and the use of clinical learning environments to foster science teacher learning.  相似文献   

A Person-Centered Approach to Students' Evaluations of Perceived Fear Appeals and Their Association With Engagement     

Laura J. Nicholson  David W. Putwain  Ghada Nakhla  Benjamin Porter  Anthony Liversidge  Monika Reece 《Journal of Experimental Education》2019,87(1):139-160

A person-centered approach was employed to investigate how students' evaluation of perceived teacher utility value messages, i.e., fear appeals, as a threat and as a challenge, combined within individuals and how these combinations related to student engagement. Two studies were conducted with students in their final two years of secondary education. Empirically distinct clusters emerged at two time points in the academic year. Evaluating the message in the fear appeal at a higher level of challenge than threat was beneficial. Unexpectedly, high threat was associated with high engagement, as long as high challenge was also present, however, this combination was also related to high emotional disaffection. Moderate threat combined with moderate challenge had the most detrimental relationship with student engagement. Educational interventions should aim to increase the likelihood of a challenge evaluation.  相似文献   

THE CONFLICT BETWEEN INTERPERSONAL RELATIONS AND ABSTRACT SYSTEMS IN EDUCATION   总被引：1，自引：0，他引：1  

Benjamin Endres 《Educational theory》2007,57(2):171-186

A bstract .  In this essay, Benjamin Endres examines how teaching is caught between the ideals of formal, systemic institutions, on the one hand, and the ideals of more intimate or personal relations, on the other. Endres uses Anthony Giddens's account of "abstract systems" and "pure" relations to suggest that the tension that teachers face is not only the result of opposing ideologies or philosophies of teaching, but it is the product of conflicting undercurrents in modern social and economic life. Although there is no simple solution to the ambiguous and contested status of teaching, Endres points to two examples of how the interpersonal dimensions of teaching may gain recognition and support by the institutional system of schooling: research on the effects of class size and legal guarantees for individualized educational plans in the area of special education. He concludes by emphasizing the particular challenge of cultivating interpersonal relations for the most disadvantaged students.  相似文献

From in-service teacher development to school improvement: factors of learning transfer in teacher education     

Benjamin Dreer  Julia Dietrich  Bärbel Kracke 《Teacher Development》2017,21(2):208-224

In-service teacher development programs are perceived as a common way to foster school improvement. Nevertheless, program evaluation to date ends with the assessment of acquired knowledge, skills, and motivation, frequently disregarding the actual learning transfer and its conditions. This study aimed to investigate how individual and situational factors interact and contribute to learning transfer in an in-service teacher development program. We tested a transfer model derived from human resources development research. One hundred and twenty-nine teachers aged 25–62 years (87% female), participating in an in-service development program, were surveyed three times during the program. Results of path analyses suggest that not only especially individual factors are critical for learning transfer in the context of school improvement, but also that program and environmental factors have important effects. They moderated the effects of the individual factors.  相似文献

Prenatal Maternal Stress,Child Cortical Thickness,and Adolescent Depressive Symptoms     

Elysia Poggi Davis  Benjamin L. Hankin  Laura M. Glynn  Kevin Head  Dae Jin Kim  Curt A. Sandman 《Child development》2020,91(2):e432-e450

Prenatal maternal stress predicts subsequent elevations in youth depressive symptoms, but the neural processes associated with these links are unclear. This study evaluated whether prenatal maternal stress is associated with child brain development, and adolescent depressive symptoms using a prospective design with 74 mother child pairs (40 boys). Maternal stress was assessed during pregnancy, child cortical thickness at age 7, and depressive symptoms at age 12. Prenatal maternal stress was associated with less cortical thickness primarily in frontal and temporal regions and with elevated depressive symptoms; child cortical thickness additionally correlated with adolescent depressive symptoms. The observed associations are consistent with the possibility that cortical thickness in superior frontal regions links associations between prenatal maternal stress and adolescent depressive symptoms.  相似文献   

Herceptin functionalized microfluidic polydimethylsiloxane devices for the capture of human epidermal growth factor receptor 2 positive circulating breast cancer cells     

Thierry B  Kurkuri M  Shi JY  Lwin LE  Palms D 《Biomicrofluidics》2010,4(3):32205

Building on recent breakthroughs in the field of microfluidic-based capture of rare cancer cells circulating in the blood, the present article reports on the use of Herceptin functionalized PDMS devices designed to efficiently capture from blood cancer cells, overexpressing the tyrosine kinase human epidermal growth factor receptor (HER2). The identification of patients overexpressing HER2 is critical as it typically associates with an aggressive disease course in breast cancer and poor prognosis. Importantly, HER2 positive patients have been found to significantly benefit from Herceptin (Trastuzumab), a humanized monoclonal antibody (MAb) against HER2. Disposable PDMS devices prepared using standard soft lithography were functionalized by the plasma polymerization of an epoxy-containing monomer. The epoxy-rich thin film (AGEpp) thus created could be conjugated with Herceptin either directly or through a polyethylene glycol interlayer. The properties and reactivity toward the monoclonal antibody conjugation of these coatings were determined using x-ray photoelectron spectroscopy; direct conjugation provided a good compromise in reactivity and resistance to biologically nonspecific fouling and was selected. Using the breast cancer cell line SK-BR-3 as a model for cells overexpressing HER2, the immunocapture efficacy of the Herceptin functionalized PDMS was demonstrated in model studies. Validation studies confirmed the ability of the device to efficiently capture (～80% capture yield) HER2 positive cells from full blood.  相似文献   

Questioning minds on the lookout for potential workplace research and improvement markers: Practice‐based research     

Benjamin E. Ruark 《Performance Improvement》2010,49(10):15-19

In the performance improvement field, performance technologists are in an ideal position to detect and investigate unexpected effects (UEs) in the workplace: those near‐invisible root variables that, once exposed, pose either potentially performance‐harming or performance‐enhancing challenges for their organization. Working with UE triggers and trends will round out performance technologists' capabilities through the adoption of what is known as practice‐based research.  相似文献
