Local equating (LE) is based on Lord's criterion of equity. It defines a family of true transformations that aim at the ideal of equitable equating. van der Linden (this issue) offers a detailed discussion of common issues in observed‐score equating relative to this local approach. By assuming an underlying item response theory model, one of the main features of LE is that it adjusts the equated raw scores using conditional distributions of raw scores given an estimate of the ability of interest. In this article, we argue that this feature disappears when using a Rasch model for the estimation of the true transformation, while the one‐parameter logistic model and the two‐parameter logistic model do provide a local adjustment of the equated score. 相似文献

Tutors often have difficulty with accurately assessing a tutee's understanding. However, little is known about whether the professional expertise of tutors influences their assessment accuracy. In this study, the authors examined the accuracy with which 21 teacher tutors and 25 student tutors assessed a tutee's understanding of the human circulatory system in the course of tutoring. The authors found that the teacher tutors were more accurate than were the student tutors in assessing whether a tutee had a low or high level of knowledge about concepts relevant to the human circulatory system. In addition, in comparison with the student teachers, the teacher tutors more accurately assessed the number of concepts that a tutee would know. However, the teacher tutors and the student tutors did poorly in assessing a tutee's mental model of the human circulatory system even though the teacher tutors were more aware of their assessment difficulties than were the student tutors. 相似文献

Learning beliefs influence learning and teaching. For this reason, teachers and teacher educators need to be aware of them. To support students’ knowledge construction, teachers must develop appropriate learning and teaching beliefs. Teachers appear to have difficulties when analysing students’ learning. This seems to be due to the inability to differentiate the beliefs about their students’ learning from those about their own learning. Both types of beliefs seem to be intertwined. This study focuses on whether pre-service teachers’ beliefs about their own learning are identical to those about their students’ learning. Using a sample of pre-service teachers, we measured general beliefs about “constructivist” and “transmissive” learning and science-specific beliefs about “connectivity” and “taking pre-concepts into account”. We also analysed the development of these four beliefs during teacher professionalisation by comparing beginning and advanced pre-service teachers. Our results show that although pre-service teachers make the distinction between their own learning and the learning of their students for the general tenets of constructivist and transmissive learning, there is no significant difference for science-specific beliefs. The beliefs pre-service teachers hold about their students’ science learning remain closely tied to their own. 相似文献

Case studies are central to the way management is currently taught at universities. Among other benefits attributed to the case study method is that it promotes networked thinking by learners. Networked thinking takes account of interactions and repercussions, making it crucial to decision-making within the complex system of rules that shapes current business reality. However, there is virtually no empirical evidence of the extent to which the case study method actually delivers the advantages attributed to it. This paper aims to remedy that gap in the literature. The paper considers the extent to which the case study method promotes networked thinking on the part of students on business and management courses. The research is designed as an intervention study involving pre- and post-testing. The study finds that students who have worked on a case study correctly identify more interactions in post-testing than in pre-testing. 相似文献

In 2015, the German Federal Ministry of Education and Research (BMBF) announced that the Science Year 2015 would focus on the “City of the Future”. It called for innovative projects from cities and communities in Germany dedicated to exploring future options and scenarios for sustainable development. Among the successful respondents was the city of Lüneburg, located in the north of Germany, which was awarded funding to establish a community learning project to envision a sustainable future (“City of the Future Lüneburg 2030+”). What made Lüneburg’s approach unique was that the city itself initiated the project and invited a broad range of stakeholders to participate in a community learning process for sustainable development. The authors of this article use the project as a blueprint for sustainable city development. Presenting a reflexive case study, they report on the process and outcomes of the project and investigate community learning processes amongst different stakeholders as an opportunity for transformative social learning. They discuss outputs and outcomes (intended as well as unintended) in relation to the specific starting points of the project to provide a context-sensitive yet rich narrative of the case and to overcome typical criticisms of case studies in the field. 相似文献

Pedagogical content knowledge of experts and novices—what knowledge do they activate when analyzing science lessons? 下载免费PDF全文
In the current debate on pedagogical content knowledge (PCK), the term is used to refer to the context‐specific knowledge that teachers activate when reflecting on practice. Against the background of this debate, we conducted an empirical study and sought to answer the question of which knowledge experts and novices activated in assessing a videotaped lesson in relation to its effectiveness for learning. Our assumption was that the participants activate their PCK as a blending of content knowledge (CK) and pedagogical knowledge (PK) as suggested by Shulman's amalgam thesis. The participants (9 experts and 9 novices) were shown a lesson on optics, in which the law of refraction (Snell's law) was being studied. In a subsequent interview, the participants were asked to analyze the observed lesson. A qualitative and quantitative evaluation of the interviews showed that experts activated both CK and PK intensively and in this respect they differed significantly from novices. Further analysis of the expert statements also proved that they do not activate their CK and PK in isolation, but instead combine both kinds of knowledge together, in line with Shulman's amalgam thesis. © 2017 Wiley Periodicals, Inc.
