French naturalists at the Muséum Nationale d'Histoire Naturelle in Paris in the early nineteenth century recognized that their individual and collective successes were intimately linked to questions of power over specimens. France's strength abroad affected the growth of the museum's collections. At the museum, preserving, naming, classifying, displaying, interpreting, and otherwise deploying specimens went hand in hand with promoting scientific theories, advancing scientific careers, and instructing the public. The control of specimens, both literally and figuratively, was the museum's ongoing concern. The leopard in this essay's title, a live specimen confiscated from the streets of Paris in 1793, serves here to represent the tensions created in an existing order of things by the introduction of a potentially disruptive agent. The essay explores the life of the museum and the interrelations among its naturalists, the special challenges created by the establishment of a menagerie, and the histories of particular specimens and ideas. 相似文献

ABSTRACT This paper compares the results of a comprehensive exam taken by undergraduates enrolled in face-to-face and online sections of a three–credit course in information literacy. Authors discuss choosing, adapting, and implementing the comprehensive exam. Questions are mapped to the ACRL Competency Standards for Information Literacy for Higher Education to assess the effectiveness of the course. Preliminary results indicate that online students performed slightly better than their face-to-face counterparts. 相似文献

When your student teacher is planning instruction, you might ask him to state his objectives in behavioral terms. Such statements may make the lesson more meaningful to both the student teacher and his pupils. 相似文献

The process of setting and evaluating student learning objectives (SLOs) has become increasingly popular as an example where classroom assessment is intended to fulfill the dual purpose use of informing instruction and holding teachers accountable. A concern is that the high‐stakes purpose may lead to distortions in the inferences about students and teachers that SLOs can support. This concern is explored in the present study by contrasting student SLO scores in a large urban school district to performance on a common objective external criterion. This external criterion is used to evaluate the extent to which student growth scores appear to be inflated. Using 2 years of data, growth comparisons are also made at the teacher level for teachers who submit SLOs and have students that take the state‐administered large‐scale assessment. Although they do show similar relationships with demographic covariates and have the same degree of stability across years, the two different measures of growth are weakly correlated. 相似文献

Abstract The purpose of this study was to construct for use by graduate students in physical education valid, reliable, and parallel forms of a test of statistical comprehension, and to develop norms to measure their level of understanding of the statistical techniques and methods that frequently appear in the RESEARCH QUARTERLY. Procedures utilized in constructing the final forms of the test were: (a) using members of the AAHPER Research Council to establish content specifications and to select specific concepts to be included in the test, (b) developing 180 experimental test items dealing with understanding of 60 statistical concepts, (c) administering three tryout test forms to 196 graduate students in physical education at 10 colleges or universities, (d) selecting, based on the tryout test data, and the table of specifications, 50 test items for each of two final test forms. Data used to evaluate the test forms and to establish norms were obtained from the administration of both forms of the test to 1,013 graduate students at 51 colleges and universities. For graduate students who have five or more semester hours of statistics and/or measurement courses, or more than 30 semester hours beyond the master's degree, the test has acceptable reliability (.79 to .91) and validity. 相似文献

In three experiments, rats received a single presentation of an auditory conditioned stimulus (CS) beginning simultaneously with an electric grid-shock unconditioned stimulus (US). Later, the CS was presented while the rats licked a drinking tube for water, and CS-elicited suppression of licking was taken as an index of the excitation conditioned to the CS. It was found that conditioning increased as a joint function of the duration of CS-US overlap and US duration. The evidence suggested that weak conditioning due to a brief CS-US overlap could be increased by extending the US beyond CS termination. Extending CS duration beyond US termination, however, did not strengthen conditioning; indeed, extending the CS 60 sec beyond US termination weakened conditioning significantly. It is suggested that these results shed light on a discrepancy in the recent literature on simultaneous conditioning. 相似文献

In this digital ITEMS module, Dr. Sue Lottridge, Amy Burkhardt, and Dr. Michelle Boyer provide an overview of automated scoring. Automated scoring is the use of computer algorithms to score unconstrained open-ended test items by mimicking human scoring. The use of automated scoring is increasing in educational assessment programs because it allows scores to be returned faster at lower cost. In the module, they discuss automated scoring from a number of perspectives. First, they discuss benefits and weaknesses of automated scoring, and what psychometricians should know about automated scoring. Next, they describe the overall process of automated scoring, moving from data collection to engine training to operational scoring. Then, they describe how automated scoring systems work, including the basic functions around score prediction as well as other flagging methods. Finally, they conclude with a discussion of the specific validity demands around automated scoring and how they align with the larger validity demands around test scores. Two data activities are provided. The first is an interactive activity that allows the user to train and evaluate a simple automated scoring engine. The second is a worked example that examines the impact of rater error on test scores. The digital module contains a link to an interactive web application as well as its R-Shiny code, diagnostic quiz questions, activities, curated resources, and a glossary. 相似文献
