This essay explores the early history of the “separate but equal”; doctrine in nineteenth century legal and political argumentation. By employing ironic and tragic frames, the authors challenge the traditional, linear approaches to legal historirizing. Moving beyond legal texts, the authors investigate how various communities in antebellum Boston negotiated conflicting views about how to best advance the cause of civil rights, both inside and outside the courtroom. These early debates created a complex rhetorical culture, and they provided jurists with several possible interpretations of the terms “separate”; and “equal.”; The authors conclude that these early debates, and Lemuel Shaw's subsequent decision in Sarah C. Roberts v. The City of Boston (1849), provide readers with insightful illustrations of the irony and tragedy of the law. 相似文献

Driven largely by calls for accountability, the use of large‐scale testing is expanding in terms of the number and purposes of testing programmes. At the same time, financial constraints have resulted in attempts to reduce the lengths of such examinations. An examination of the 1994/1995 and 1995/1996 British Columbia Scholarship programme illustrates that differential and unanticipated differences can occur when such changes to the testing programme are made. The removal of a portion of the constructed‐response (CR) and written tasks (WT) items used to identify scholarship recipients resulted in differences in scholarship scores and the identification of scholarship recipients. Further, the differences were found to affect subgroups of students differentially. While there were no differences attributed to gender, higher difference rates were associated with course area (humanities vs. science) or examination session (January vs. June). The results illustrate the complex and contextual impact of changes to examination programmes and the potential consequences of such changes. Test developers and users must make more of an effort to examine the consequences of examination programmes and planned changes upon the students and others who may be affected by the results. 相似文献

The authors report on an exploratory study that investigated Grade 10 students’ responses to a large-scale, high-stakes literacy test, the results of which determine high school graduation in Ontario, Canada. Through focus-group and individual interviews, the authors found that students perceived the test as evaluating their English skills rather than their cross-curricular literacy as is the stated purpose by the test administrators. Furthermore, the test contributed to students’ narrow definition of writing. Rather than promoting writing as a powerful tool for thinking and expressing ideas, students understood writing to be a fill-in-the-blanks response to particular genres. The authors conclude by pointing out the power of such tests to define unintended learning in schools. 相似文献

Studies of adults and infants indicate that the left frontal brain region is specialized for approach emotions, such as joy, whereas the right frontal region is specialized for withdrawal emotions, such as distress. Furthermore, depressed adults have been found to show reduced brain activity in the left frontal region. In this study, frontal and parietal electroencephalographic (EEG) activity was recorded from 27 infants aged 11-17 months (13 of whose mothers reported elevated depressive symptoms) during baseline and emotion-eliciting conditions. Compared with infants of nonsymptomatic mothers, infants of symptomatic mothers exhibited reduced left frontal brain activity during playful interactions with their mothers and failed to exhibit the typical pattern of greater right frontal activity during a condition designed to elicit distress (maternal separation). Infants of symptomatic mothers also showed less distress during maternal separation; however, no group differences in behavior were found during the playful condition. Group differences were evident in the frontal region, but not in parietal brain activity. 相似文献

In test development, item response theory (IRT) is a method to determine the amount of information that each item (i.e., item information function) and combination of items (i.e., test information function) provide in the estimation of an examinee's ability. Studies investigating the effects of item parameter estimation errors over a range of ability have demonstrated an overestimation of information when the most discriminating items are selected (i.e., item selection based on maximum information). In the present study, the authors examined the influence of item parameter estimation errors across 3 item selection methods—maximum no target, maximum target, and theta maximum—using the 2- and 3-parameter logistic IRT models. Tests created with the maximum no target and maximum target item selection procedures consistently overestimated the test information function. Conversely, tests created using the theta maximum item selection procedure yielded more consistent estimates of the test information function and, at times, underestimated the test information function. Implications for test development are discussed. 相似文献

The 4Ps activity provides a unique approach to first-day class introductions and creates a positive classroom climate that encourages student engagement. The assignment generates initial self-disclosure that facilitates interpersonal and group communication throughout the semester. Additionally, the activity can be used as a unit activity with a follow-up assignment that introduces foundational public speaking concepts.
Courses: Public Speaking, Interpersonal, and other communication courses.
Objectives:
To promote connectedness within the class from the first meeting forward
To extend the usual “icebreaker” in a meaningful way by incorporating a public-speaking assignment
To provide a basis for discussion of key communication concepts such as self-disclosure, relational development, and stereotyping.
