Standard-setting procedures are a key component within many large-scale educational assessment systems. They are consensual approaches in which committees of experts set cut-scores on continuous proficiency scales, which facilitate communication of proficiency distributions of students to a wide variety of stakeholders. This communicative function makes standard-setting studies a key gateway for validity concerns at the intersection of evidentiary and consequential aspects of score interpretations. This short review paper describes the conceptual and empirical basis of validity arguments for standard-setting procedures in light of recent research on validity theory. It specifically demonstrates how procedural and internal evidence for the validity of standard-setting procedures can be collected to form part of the consequential basis of validity evidence for test use. 相似文献

Academic self-concept, interest, grades, and standardized test scores: reciprocal effects models of causal ordering 总被引：1，自引：0，他引：1
Reciprocal effects models of longitudinal data show that academic self-concept is both a cause and an effect of achievement. In this study this model was extended to juxtapose self-concept with academic interest. Based on longitudinal data from 2 nationally representative samples of German 7th-grade students (Study 1: N = 5,649, M age = 13.4; Study 2: N = 2,264, M age = 13.7 years), prior self-concept significantly affected subsequent math interest, school grades, and standardized test scores, whereas prior math interest had only a small effect on subsequent math self-concept. Despite stereotypic gender differences in means, linkages relating these constructs were invariant over gender. These results demonstrate the positive effects of academic self-concept on a variety of academic outcomes and integrate self-concept with the developmental motivation literature. 相似文献

This article uses a form of multi‐dimensional statistical analysis, so‐called LISREL analysis, as developed by Jöreskog and Sörbom, to analyze the interrelationships of fourteen variable elements influencing higher education policy. The aim of the method is to discover which elements carry the greatest weight and in relationship to which others as linked to the tension between higher education and government. A number of possibilities could be proved by this method, in particular, the increasing importance of internationalization as an element in national higher education policies. 相似文献

Until recently, the physiological demands of cycling competitions were mostly reflected by the measurement of heart rate and the indirect estimation of exercise intensity. The purpose of this case study was to illustrate the varying power output of a professional cyclist during flat and mountain stages of a Grand Tour (Giro d'Italia). Nine stage recordings of a cyclist of the 2005 Giro d'Italia were monitored using a mobile power measurement device (SRM Trainingssystem, Julich, Germany), which recorded direct power output and heart rate. Stages were categorized into flat (n = 5) and mountain stages (n = 4). Data were processed electronically, and the overall mean power in flat and mountain stages and maximal mean power for various durations were calculated. Mean power output was 132 W +/- 26 (2.0 W x kg(-1) +/- 0.4) for the flat and 235 W +/- 10 (3.5 W x kg(-1) +/- 0.1) for the mountain stages. Mountain stages showed higher maximal mean power (367 W) for longer durations (1800 s) than flat stages (239 W). Flat stages are characterized by a large variability of power output with short bursts of high power and long periods with reduced intensity of exercise, whereas mountain stages mostly require submaximal, constant power output over longer periods. 相似文献

Prior research indicates that social behavior contributes to school achievement. The underlying mechanisms, however, have received little research attention to date. To investigate peer acceptance as mediating the influences of prosocial and antisocial behavior on school grades, this prospective study draws on 2387 ninth graders. All students in a class rated their peers in terms of prosocial and antisocial behavior, class teachers rated their students’ peer acceptance in class, and grades in German and mathematics were collected from students’ report cards. Prior report card grades, gender and socioeconomic status were controlled for. Structural equation modeling shows direct positive paths between prosocial behavior and both peer acceptance and grades; antisocial behavior negatively predicted both peer acceptance and grades. Prosocial behavior contributed to better grades via higher peer acceptance, whereas concerning antisocial behavior, the mediating effect was statistically not significant. Results are discussed with regard to their practical relevance and implications for future research. 相似文献

The Reading Acceleration Program (RAP), which uses adaptively increasing text erasure rates to enforce reading rate improvements, has been positively evaluated in various languages, reader and age groups. The current study compared the established incremental increase of text erasure rate with a training using fixed erasure rates in two groups of young, non-impaired German adults. Eye-tracking measures prior and post training examined training-related changes of eye-movement patterns. Equal gains in reading performance in both training groups led to the conclusion that not the adaptive increase but already text erasure at fixed rates provides an economically efficient tool for the enhancement of reading rates. Furthermore, eye-tracking results suggest that text erasure training affects word processing not only at one specific level, but simultaneously at pre-lexical, lexical, and post-lexical stages. Although these outcomes are promising, further research is necessary to determine the optimal individual erasure rates that preserve good comprehension at varying levels of text difficulty and in different orthographies. 相似文献

This paper presents data from a project onmoral motivation. It is more pragmaticallyframed on what it is that attracts students to`untrendy' fields and makes them want to do agood job. As the value structure in societychanges and the battle for students hardens,there is a growing concern that fields crucialto the development of society may lose out inthe competition for the best students. Amongthe fields that have received attention inthese debates are nursing and social work. Inpart, this is due to the fact that these fieldshave already experienced a decline inapplicants which merits concern, and in partdue to the image these studiesproject. In the debate on intake qualitiesfocus has primarily been on the academicquality of the students, and less on themotivational qualities that work of this typeimplies. The data presented here highlightsqualities related to this dimension ofprofessional work. 相似文献
