In this article, we introduce a section preequating (SPE) method (linear and nonlinear) under the randomly equivalent groups design. In this equating design, sections of Test X (a future new form) and another existing Test Y (an old form already on scale) are administered. The sections of Test X are equated to Test Y, after adjusting for the imperfect correlation between sections of Test X, to obtain the equated score on the complete form of X. Simulations and a real‐data application show that the proposed SPE method is fairly simple and accurate.  相似文献

Growing evidence exists that the findings of individual studies—including classic experiments—often fail to replicate. Such published results, however, are considered by scholars, and taught to students, as established scientific truth. In this context, citations to Zimbardo and colleagues’ classic Stanford Prison Experiment (SPE) in criminology/criminal justice journals (1975–2014) were content analyzed to assess whether the study’s conclusions have been embraced or treated with skepticism. The data revealed that scholars were widely accepting of the SPE and, even when voicing concerns, supportive of its message. These results suggest the need to give replications higher priority and for scholars to adhere more closely to the scientific norm of organized skepticism. In the classroom, the continued, uncritical acceptance of the SPE—now more than 40 years old—can serve as an opportunity to teach students about the production and assessment of knowledge within criminology.  相似文献

This paper summarises a new method of grouping postgraduate taught (PGT) courses introduced at Oxford Brookes University as a part of a Portfolio Review. Instead of classifying courses by subject, the new cluster approach uses statistical methods to group the courses based on factors including flexibility of study options, level of specialisation, research links, vocational character and undergraduate continuity. The model of five defined clusters helps understand an increasing diversity of PGT provision better, find similarities outside of traditional subject divisions and share a good practice outside of the departmental structure of the University. It can assist with a new approach to University-wide marketing activities as well as with evaluation of performance taking into account course specifics within the clusters. The paper proposes a set of new and tailored performance indicators for PGT courses.  相似文献

Self-biases are well described in adults but remain poorly understood in children. Here, we investigated in 6–10 year-old children (N = 132) the self-prioritization effect (SPE), a self-bias which reflects, in adults, the perceptual advantage for stimuli arbitrarily associated with the self as compared to those associated with other persons. We designed a child-friendly adaptation of a paradigm originally introduced in adults by Sui, He, and Humphreys (2012) in order to test whether the SPE also occurs in children and if so, to determine its evolution with age. A robust SPE was obtained from the age of 6, and this effect was similar-sized in our four age groups. These findings are discussed with reference to the development of the self during childhood.  相似文献

This study assessed the explanatory power of the intellectual competence (IC) model for understanding the relationship among the main ability and non-ability determinants of academic performance (AP) in a sample of Spanish undergraduates. Thus it attempted to replicate the preliminary evidence for this model provided in a recent UK study and expand on it by including more comprehensive measures of intelligence and AP. Results showed mixed support for individual paths, but good support for the overall model. The expanded IC model showed that some individual difference factors explain AP variance that is common to high school, university entry, and university exam grades, whereas other individual differences explained AP variance specific to university. Inconsistencies, limitations, and implications are discussed.  相似文献
