Qualitatively analyzing 35 responses from a letter-writing homework in a media literacy education program, this study examines sixth graders’ understandings of producers’ responsibility in creating media content. Responses suggest their understandings about producers’ responsibility are bounded within the context of their media use as consumers, rather than as citizens. Findings focus on the importance of introducing contextual factors of media production as well as the challenges that researchers and educators might face. 相似文献

ABSTRACT: This analysis documents the outcomes and impacts from a series of food protection and defense educational programs conducted over a 3‐y period for private and public sector food system professionals. Several measures were used to determine the professions of participants; their improvements in skills and abilities that resulted from workshops; the audiences' most valued program content; practice changes resulting from educational program participation; abilities to recognize and change food system vulnerabilities; and changes in knowledge levels. Findings indicate that the knowledge level and interest within the target audience progressed over the 3‐y period from basic awareness level through more complex and higher order skills and competencies such as being able to walk through a food production, processing, distribution, or retail facility and identify specific vulnerabilities and make specific risk control recommendations. Pre‐ and posttest scores from the 3rd y of educational activities indicate that baseline awareness levels of core content on food protection and defense is now high among those most likely to attend these types of events, and that participants need to be challenged with additional higher‐level education to promote specific skills. This program series proved successful in building important relationships among food industry and regulatory partners. Analysis of the food security investigation (FSI) series will be useful in the development and delivery of new education and outreach efforts. It is hoped that the analysis and discussion will provide the motivation to further develop a set of competencies that can be used to ground educational efforts that focus on securing and defending our food system. 相似文献

To test the hypothesis that the etiology of reading difficulties may differ for males and females in more severely impaired
samples, reading performance data from monozygotic (MZ), same-sex dizygotic (DZss), and opposite-sex dizygotic (DZos) twin pairs were analyzed using a model-fitting implementation of the DeFries-Fulker (DF) model (Purcell & Sham, 2003, Behavior genetics, 33, 271–278). Five non-independent samples were selected using cut-offs of −1 (N = 737 pairs), −1.5 (N = 654), −2 (N = 468), −2.5 (N = 335), and −3 (N = 198) standard deviations (s) below the mean composite reading score of control twins. Male/female gender ratios for children
with reading difficulties were significantly higher than 1.0 for all five samples and increased as a function of severity
(viz., 1.15, 1.17, 1.40, 1.61, and 1.88, respectively). When the DF model was fit to the data, estimates of heritability (h
g2) and shared environmental influences (c
g2) were not significantly different for males and females in any of the groups. Consequently, the most parsimonious model that
provided a good fit to the data at all five levels of severity equated the heritabilities and shared environmental influences
for males and females, and fixed the DZos coefficient of genetic relatedness at 0.5. Thus, these results provide no evidence for a differential etiology of reading
difficulties as a function of gender in more severely impaired samples, and suggest that the same genetic and environmental
influences contribute to reading difficulties in males and females, irrespective of severity. 相似文献

Genomics and bioinformatics are topics of increasing interest in undergraduate biological science curricula. Many existing exercises focus on gene annotation and analysis of a single genome. In this paper, we present two educational modules designed to enable students to learn and apply fundamental concepts in comparative genomics using examples related to bacterial pathogenesis. Students first examine alignments of genomes of Escherichia coli O157:H7 strains isolated from three food-poisoning outbreaks using the multiple-genome alignment tool Mauve. Students investigate conservation of virulence factors using the Mauve viewer and by browsing annotations available at the A Systematic Annotation Package for Community Analysis of Genomes database. In the second module, students use an alignment of five Yersinia pestis genomes to analyze single-nucleotide polymorphisms of three genes to classify strains into biovar groups. Students are then given sequences of bacterial DNA amplified from the teeth of corpses from the first and second pandemics of the bubonic plague and asked to classify these new samples. Learning-assessment results reveal student improvement in self-efficacy and content knowledge, as well as students' ability to use BLAST to identify genomic islands and conduct analyses of virulence factors from E. coli O157:H7 or Y. pestis. Each of these educational modules offers educators new ready-to-implement resources for integrating comparative genomic topics into their curricula. 相似文献

This teaching brief presents a capstone project designed to provide students with a contextual understanding of introductory management accounting theories through hands-on, experiential learning. It also exposes them to cross-disciplinary roles from operations management. Using this capstone approach, students quickly learn to prepare financial projections, either manually or in Microsoft Excel, to secure financing for their start-up business (Sand Art Brownie Company or SABCO) to produce and sell brownie mix during the holiday season. Students then assemble ingredients and create jars of brownie mix to gather the necessary data to evaluate initial projections and problem-solve for future production. This role play contextualizes the elements of direct and indirect labor, fixed and variable costs, and their impact on profit and borrowing. Postproduction reflection on the manufacturing activities and discussion of actual results of operations emphasizes the improvement and decision-making responsibilities in the management process. Feedback demonstrates that students find the exercise challenging and valuable and that it deepens their understanding of managerial accounting and its purpose in a company's management process. 相似文献

Clinical supervisors should be culturally competent working with transgender or gender expansive (TGE) counselors-in-training; however, minimal research exists regarding TGE counselors’ experiences in supervision. This interpretative phenomenological analysis study explored the supervision experiences of five TGE counselors-in-training. Findings revealed four super-ordinate themes and two sub-themes, and implications are discussed. 相似文献
