Legal and Psychometric Criteria for Evaluating Teacher Certification Tests     

Stephen G. Sireci  Preston C. Green  III 《Educational Measurement》2000,19(1):22-31

Will our teacher certification testing program stand up to a court challenge? What are the critical issues the courts consider in examining teacher certification testing? What do we need to do to strengthen our program legally and psychometrically?  相似文献   

Informing in the Information Age: How to Communicate Measurement Concepts to Education Policy Makers     

Stephen G. Sireci  Ellen Forte 《Educational Measurement》2012,31(2):27-32

Current educational policies rely on educational assessments. However, the technical aspects of assessments are often unknown to policy makers, which is dangerous because sound assessment policy requires knowledge of the strengths and limitations of educational tests. In this article, we discuss the importance of informing policy makers of important psychometric issues that should be considered whenever tests are proposed for specific purposes. We discuss the types of information that are important to communicate to policy makers, how to best convey this information in a manner in which it can be understood, and how to be seen as a valuable source of information to education policy makers. We end with some specific steps organizations such as NCME can take to inform policy makers and advocate for valid educational assessment policies.  相似文献

An objective method for depicting team performance in elite professional rugby union     

Jones NM  James N  Mellalieu SD 《Journal of sports sciences》2008,26(7):691-700

Using a two-study approach, we examined a methodology for objectively depicting team performance and form in a professional rugby union side. Study 1 developed standardized indicators to examine a team's performance in a single match relative to their previous matches over a domestic season via a performance report and form chart. This resulted in standardized performance indicators that provided instant and coherent feedback on the team's performance relative to previous standards. Study 2 then utilized this methodology to compare a match between two professional sides, played the following season, to assess the extent to which the performance by one team affected that of the other. Comparison of the two teams' performances, for the match they played against each other, identified a drop in relative performance (against previous standards) for both teams on the same performance indicators. This appeared to be due to the match being a close, hard-fought contest particularly in the tackle and around the gain-line. The findings of the two studies suggest an accurate and viable methodology for depicting team performance that is superior to the global measures previously adopted. Presenting teams' current standardized performances (i.e. form) on a single visual scale also has utility for coaches within an applied setting. Future research should further investigate the effect of one team's performance on another through both individual and team outcomes.  相似文献   

Numerical modelling of rowing blade hydrodynamics     

Andrew Sliasas  Stephen Tullis 《Sports Engineering》2009,12(1):31-40

The highly unsteady flow around a rowing blade in motion is examined using a three-dimensional computational fluid dynamics (CFD) model which accounts for the interaction of the blade with the free surface of the water. The model is validated using previous experimental results for quarter-scale blades held stationary near the surface in a water flume. Steady-state drag and lift coefficients from the quarter-scale blade flume simulation are compared to those from a simulation of the more realistic case of a full-scale blade in open water. The model is then modified to accommodate blade motion by simulating the unsteady motion of the rowing shell moving through the water, and the sweep of the oar blade with respect to the shell. Qualitatively, the motion of the free surface around the blade during a stroke shows a realistic agreement with the actual deformation encountered during rowing. Drag and lift coefficients calculated for the blade during a stroke show that the transient hydrodynamic behaviour of the blade in motion differs substantially from the stationary case.  相似文献   

The practice of brand extension through licensing: The Spalding challenge     

Joe Cobbs  Stephen McKelvey 《Sport Management Review》2009,12(3):185-192

In this case study, the Russell Corporation's acquisition of Spalding creates an opportunity for Spalding's marketing staff to reevaluate their licensing strategy. Prior ownership has heavily leveraged the equity of the Spalding brand to generate maximum licensing revenues with a minimal concern for the long-term impact on the brand. Placed in the position of Spalding's Vice President for Marketing, the reader must grapple with strategic licensing factors such as the rise of the big-box retailer in distribution channels and product category congruence across extensions. Ultimately, with several licensing contracts up for renewal, a decision on the future direction of the Spalding brand must be outlined and defended in a presentation to the executives at Russell.  相似文献

Validity Issues in Test Speededness     

Ying Lu  Stephen G. Sireci 《Educational Measurement》2007,26(4):29-37

Speededness refers to the situation where the time limits on a standardized test do not allow substantial numbers of examinees to fully consider all test items. When tests are not intended to measure speed of responding, speededness introduces a severe threat to the validity of interpretations based on test scores. In this article, we describe test speededness, its potential threats to validity, and traditional and modern methods that can be used to assess the presence of speededness. We argue that more attention must be paid to this issue and that more research must be done to set appropriate time limits on power tests so that speed of responding does not interfere with the construct measured.  相似文献
