In order to design two distinct engineering qualification levels for an existing University of Technology programme, empirical evidence based on the current diploma is necessary to illuminate the nature of and the relationship between the contextual and conceptual elements underpinning a multidisciplinary engineering curriculum. The increasing focus on contextual application could result in decreasing opportunities to develop the conceptual disciplinary grasp required for a dynamic, emerging region at the forefront of technological innovation. Using the theoretical tools of Bernstein and Maton to analyse final year student practice, the research addresses the question of how multidisciplinary knowledge is integrated by students, and what this reveals about the nature of such knowledge. The paper presents a conceptualisation of multidisciplinary knowledge integration practices as a dynamic process along two axes simultaneously, shifting between different forms and levels of conceptual and contextual knowledge. 相似文献

Abstract Understanding teachers' perceptions of a web-based, case-based learning environment provides insight into the effective development and deployment of such conditions for preparing educators. CaseNET–a web-based, case-method teaching environment for professional educators–serves as both a source of information as well as a space for inservice and preservice teachers to interact with one another and to contemplate current educational issues as they relate to real-world teaching. A qualitative analysis of over 400 participants was conducted and results provided. Participants perceived CaseNETas an opportunity to engage in professional development via exploration, reflection, collaboration, and hands-on interactions with authentic teaching tasks. Results suggest that the combination of cases and technology provides a valued opportunity to engage developing teachers in professional behaviors. 相似文献

Following Cronbach (1970) and others, it is useful to decompose test score variation into common factor, time‐specific, item‐specific, and residual components. In the traditional approach to factor analysis, only two sources of variance can be estimated: common factor variance and a uniqueness term that confounds specific sources of variation and residual error. When the same items are measured on different occasions, however, it is possible to separate specific variance and residual error. Two approaches, the first‐order approach described by Raffalovich and Bohrnstedt (1987) and a second‐order approach based on Jöreskog and Sörbom (1989; Jöreskog, 1974) are considered initially. The two approaches, although based on different rationales, both suffer a similar weakness in that two of the four sources of variance are confounded. In the Raffalovich and Bohrnstedt approach, time‐specific variance is confounded with common factor variance that generalizes across items and time. In the second‐order approach based on Jöreskog and Sörbom, time‐specific variance is confounded with residual error. Here we demonstrate that by combining features from both approaches we can eliminate these weaknesses and estimate all four of Cronbach's sources of variance, and that this combined approach is easily generalized to a wide variety of applications. 相似文献
