Constituting a metacognitive strategy, system competence or systems thinking can only assume its assigned key function as a basic concept for the school subject of geography in Germany after a theoretical and empirical foundation has been established. A measurement instrument is required which is suitable both for supporting students and for the evaluation of methodical‐didactic measures. Such a tool is theoretically anchored in an empirically validated geography‐didactic and cognition‐psychological competence model, providing a differentiated representation of both the internal structure of a competency and the proficiency levels. The starting point of this foundation was the development of a normative‐theoretically derived model of geographic system competence. Its empirical validation was performed in different phases aimed at operationalising the competence model by means of test problems. In order to analyse the factor structure of the theoretical model, various item response models were estimated. The item levels of difficulty expected in the competence model were related to the empirical levels of difficulty and predicted by means of ordinary least squares regression to verify the model for proficiency levels. The two‐dimensional competence model – with the two dimensions ‘system organisation and behaviour’ and ‘system‐adequate intention to act’ – exhibits a better fit in reference to the model fit criteria than the one‐dimensional and three‐dimensional models. The correlations between the expected and empirical item difficulties are positive. Items that should be more difficult according to the competence model are actually shown to be more difficult. These findings suggest the reliability and validity of this new measurement instrument for diagnosing and promoting geographical system competence. It has to be implemented in practice as the next step. 相似文献

Valid and reliable standardized assessment of nursing competencies is needed to monitor the quality of vocational education and training (VET) in nursing and evaluate learning outcomes for care work trainees with increasingly heterogeneous learning backgrounds. To date, however, the modeling of professional competencies has not yet evolved into procedures that would meet large-scale assessment (LSA) standards in VET. To empirically test a proposed structural model for client-directed nursing competence and to estimate psychometric properties of a newly developed video- and computer-based test (CBT) to inform subsequent LSA in nursing VET, 402 final-year nursing students from 24 German schools responded to a 77 item CBT. Multi-dimensional IRT modeling was employed to test the subdomain structure and estimate students’ competencies in geriatric nursing. The standardized CBT measures nursing students’ client-directed care competence with acceptable precision (WLE?=?0.76) and does so across the whole range of observed proficiency levels. Structural validity was supported by substantive contributions of test items from all proposed process-oriented subdomains, practice field scenarios, as well as items with and without reference to emotional demands. However, it was not possible to empirically separate the diagnostic, practical or communicative subdomains, probably reflecting parallel, recursive and hierarchical care processes in complex care situations. On average, students in our sample attained 45 % of the maximum test score so it is a demanding assessment of nursing competence. An extensively piloted, valid and reliable CBT is suggested to assess nursing students’ client-directed care competencies at the end of the third year of the VET program. 相似文献

Currently, competencies are mostly assessed with paper and pencil tests. Nevertheless, for some competencies, using paper and pencil tests is problematic for three reasons. For (a) competencies requiring complex interactions under time constraints, (b) complex competence constructs, and (c) competencies requiring using a computer, a computer-based assessment provides several advantages compared to a paper and pencil-based assessment. Nevertheless, none of the two testing media is superior to the other in a general way. Thus, the testing medium which provides the best opportunities for a proper operationalization of the competence construct at stake should be selected. If both paper and pencil and computer seem applicable for measuring a competence construct, precisely costing out and comparing the two alternatives is recommended. Within this comparison, not only the additional costs caused by using computers but also the specific costs of paper and pencil-based assessment should be considered. 相似文献

Abstract The perception that Internet plagiarism by university students is on the rise has alarmed college teachers, leading to the adoption of electronic plagiarism checkers, among other responses. Although some recent studies suggest that estimates of online plagiarism may be exaggerated, cause for concern remains. This article reviews quantitative studies of student plagiarism over the past forty years, as well as academe's generally weak response. It also offers strategies for addressing cyber-plagiarism and argues that faculty should act as educators, rather than as detectives. 相似文献

Multidimensional item response theory (MIRT) provides an ideal foundation for modeling performance in complex domains, taking into account multiple basic abilities simultaneously, and representing different mixtures of the abilities required for different test items. This article provides a brief overview of different MIRT models, and the substantive implications of their differences for educational assessment. To illustrate the flexibility and benefits of MIRT, three application scenarios are described: to account for unintended multidimensionality when measuring a unidimensional construct, to model latent covariance structures between ability dimensions, and to model interactions of multiple abilities required for solving specific test items. All of these scenarios are illustrated by empirical examples. Finally, the implications of using MIRT models on educational processes are discussed. 相似文献

Students’ performance in assessments is commonly attributed to more or less effective teaching. This implies that students’ responses are significantly affected by instruction. However, the assumption that outcome measures indeed are instructionally sensitive is scarcely investigated empirically. In the present study, we propose a longitudinal multilevel‐differential item functioning (DIF) model to combine two existing yet independent approaches to evaluate items’ instructional sensitivity. The model permits for a more informative judgment of instructional sensitivity, allowing the distinction of global and differential sensitivity. Exemplarily, the model is applied to two empirical data sets, with classical indices (Pretest–Posttest Difference Index and posttest multilevel‐DIF) computed for comparison. Results suggest that the approach works well in the application to empirical data, and may provide important information to test developers. 相似文献

An NCME Instructional Module on Booklet Designs in Large-Scale Assessments of Student Achievement: Theory and Practice 总被引：2，自引：0，他引：2
In most large-scale assessments of student achievement, several broad content domains are tested. Because more items are needed to cover the content domains than can be presented in the limited testing time to each individual student, multiple test forms or booklets are utilized to distribute the items to the students. The construction of an appropriate booklet design is a complex and challenging endeavor that has far-reaching implications for data calibration and score reporting. This module describes the construction of booklet designs as the task of allocating items to booklets under context-specific constraints. Several types of experimental designs are presented that can be used as booklet designs. The theoretical properties and construction principles for each type of design are discussed and illustrated with examples. Finally, the evaluation of booklet designs is described and future directions for researching, teaching, and reporting on booklet designs for large-scale assessments of student achievement are identified. 相似文献
