The purpose of this study was to investigate the practicality of extending the Multidimensional Self Concept Scale (MSCS) norms downward for use with third and fourth grade students from a predominantly African-American sample. This research compared domain-specific and general self-concepts by grade, gender, and race among third through sixth grade students. Comparison was also made between fifth and sixth grade students in this sample and fifth and sixth grade students in the national standardization sample. It was concluded that no meaningful differences existed between the present sample of fifth and sixth grade students and the standardization sample of fifth and sixth grade students. However, differences found between the third through sixth grade students in this sample were significant and clinically meaningful for the Total Scale score and for all scales, except the Academic and Physical scales. Although the existing norms for the Academic and Physical scales appear appropriate for the younger children, separate norm tables appear warranted for the remaining subscales and Total Scale. Internal consistency for the MSCS for third and fourth grade students was comparable to the fifth and sixth grade students in this sample. © 1998 John Wiley & Sons, Inc. 相似文献

One of the canons that guides the design of microcomputer-based instructional programs is to use a self-paced instructional method. However, there has been some indication that moderate levels of external pacing may prove to be more effective for overall learning, in terms of amount of content acquired and level of competency achieved with that content. Hypotheses derived from this idea were tested using three types of pacing. Learning was evaluated using five achievement tests ranging in difficulty from memorizing facts to problem solving. Experimental results supported the hypothesis favoring moderate levels of external pacing and found that the common principle of using self-paced instructional methods as the best style for all types of microcomputer instruction is an incorrect assumption. 相似文献

In November 2002, the multisite Conference on the Future of School Psychology was sponsored by major professional associations of school psychologists. Conference goals included achieving consensus on current and future demands for school, conceptualizing the practice of school psychology in the face of diminishing numbers and increasing demand for services, and developing an agenda to use school psychology resources to maximize the benefits to the children and schools. Consultation, intervention, and prevention were major themes in all conference activities. The present article provides an overview of the conference and a summary of issues and outcomes from the conference that relate to educational and psychological consultation services. 相似文献

This article was written by Patti Gibbons and Debra A. Werner. Patti is the Head of Collection Management at the University of Chicago Library’s Special Collections Research Center and holds a MLIS from the University of Illinois and a MA from the University of Washington. Debra is the Librarian for Science Instruction & Outreach and Biomedical Reference Librarian at the University of Chicago Library and the University of Chicago’s Pritzker School of Medicine’s Director of Library Research in Medical Education and she holds a MLIS from Dominican University. This article covers an experimental project at the University of Chicago where the library’s medical librarian teamed up with the hospital’s clinical team during patient rounds to provide real-time reference services. The project’s effectiveness was studied by a medical student who found that the embedded librarian’s services improved the clinical team’s evidence-based medical decision-making abilities without increasing the length of bedside rounds. 相似文献

The activity of a calmodulin antagonist, trifluoperazine (TFP), was testedin vitro againstMycobacterium avium (ATCC 25291). The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of this compound forM. avium were 20 and 30 μg/ml, respectively. TFP was also found to completely inhibit the growth of 10 isolates ofM. avium (5 patient isolates and 5 environmental isolates) at 30 μg/ml. At near neutral pH (6.8), the MIC of TFP was found to be 20 μg/ml. However, at pH 5.5 (intracellular pH of macrophages), there was a decrease in the inhibitory activity of the compound against this organism. Interestingly, 99.6% ofM. avium within human monocyte-derived macrophages were killed at a drug concentration of 30 μg/ml, which correlates well with the MBC of TFP againstM. avium in vitro. Although the MIC for TFP appears to be higher than that forMycobacterium tuberculosis H37Rv, our studies suggest that calmodulin antagonists might be useful as drugs against infection due toM. avium. It is suggested that administration of TFP in combination with other known drugs may enhance the overall bactericidal effect. 相似文献

ABSTRACT This article—co-authored by a transdisciplinary team of social scientists and journalists in the United States—traces changes to the news landscape in recent decades, and asks: How are legacy media producers grappling with these new realities? As part of a four-year collaboration on young adult news consumption, we take a participatory action research approach to this question, tacking back and forth between newsroom concepts and anthropological ones in pursuit of a synthesis that strengthens both. Starting from anthropological frameworks of participation, the authors argue that broadcast videos typically position their audiences as overhearers rather than interlocutors, while the reverse is true for social media, and that these tendencies shape audience expectations. We find that many audiences have what we call poetic motivations: they are drawn to stories that exemplify their genre. For example, the participatory nature of social media genres translates well to a more candid style that can incorporate live questions and other direct participation. The study reported here focuses on STEM news, but many of the findings apply to news production in general. Our reflective methods can also be applied more widely in the field of journalism to synthesize perspectives from theory and practice. 相似文献

Although the rubric has emerged as one of the most popular assessment tools in progressive educational programs, there is an unfortunate dearth of information in the literature quantifying the actual effectiveness of the rubric as an assessment tool in the hands of the students. This study focuses on the validity and reliability of the rubric as an assessment tool for student peer‐group evaluation in an effort to further explore the use and effectiveness of the rubric. A total of 1577 peer‐group ratings using a rubric for an oral presentation was used in this 3‐year study involving 107 college biology students. A quantitative analysis of the rubric used in this study shows that it is used consistently by both students and the instructor across the study years. Moreover, the rubric appears to be ‘gender neutral’ and the students' academic strength has no significant bearing on the way that they employ the rubric. A significant, one‐to‐one relationship (slope = 1.0) between the instructor's assessment and the students' rating is seen across all years using the rubric. A generalizability study yields estimates of inter‐rater reliability of moderate values across all years and allows for the estimation of variance components. Taken together, these data indicate that the general form and evaluative criteria of the rubric are clear and that the rubric is a useful assessment tool for peer‐group (and self‐) assessment by students. To our knowledge, these data provide the first statistical documentation of the validity and reliability of the rubric for student peer‐group assessment. 相似文献
