Abstract Present athletic practices in stop-watch timing require the median of three watch times to be declared “official” time. Theoretical evidence is available that the standard error of the median is larger than the standard error of the mean when sampling is from a single, normal population. The present investigation was designed to determine if, under actual race conditions, the same relationship between the mean and median time exists. In the two independent experiments described the standard error of the median was observed to be larger than that of the mean. 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

AbstractIn this paper we address practical questions such as: How do symbols appear and evolve in an inquiry-oriented classroom? How can an instructor connect students with traditional notation and vocabulary without undermining their sense of ownership of the material? We tender an example from linear algebra that highlights the roles of the instructor as a broker, and the ways in which students participate in the practice of symbolizing as they reinvent the diagonalization equation A = PDP?1. 相似文献

The Social Skills Improvement System-Rating Scales (SSIS-RS) is a multi-informant instrument assessing social skills and problem behavior in children and adolescents. It is a revised version of the Social Skills Rating System (SSRS). A Norwegian translation of the SSRS has been validated, but this has not yet been done for the Norwegian translation of the SSIS-RS. This study compared the Norwegian versions of the SSRS and the SSIS-RS administered to samples of children (aged 8–12 and 13–16?years) and their parents and teachers (n = 599). The results indicated moderate to strong relations between the common subscales across all forms of the two instruments and acceptable to excellent internal consistency across all common subscales. We conclude that the SSIS-RS is a good instrument for measuring social skills and problem behavior among children and adolescents in Norway. 相似文献

In this report, we adapt and extend a methodology for documenting the collective production of meaning in a classroom community.
A cornerstone of the methodological approach that we develop is a close examination of classroom discourse. Our efforts to
analyze the collective production of meaning by examining classroom interaction are compatible with the relatively recent
emphasis in mathematics and science education research that focuses on how communities of learners establish ideas through
discourse and inquiry. The methodological approach we take builds on and extends an approach from mathematics education that
uses Toulmin’s argumentation model to document and analyze students’ conceptual progress. Our modification introduces a new
criterion for empirically demonstrating when particular ways of reasoning become part of the normative practices of the community.
An example from an undergraduate course in physical chemistry is used to illustrate the methodology. 相似文献
