Collaborations between researchers and practitioners have recently become increasingly popular in education, and educational design research (EDR) may benefit greatly from investigating such partnerships. One important domain in which EDR on collaborations between researchers and practitioners can be applied is research on simulation-based learning. However, frameworks describing both research and design processes in research programs on simulation-based learning are currently lacking. The framework proposed in this paper addresses this research gap. It is derived from theory and delineates levels, phases, activities, roles, and products of research programs to develop simulations as complex scientific artifacts for research purposes. This dual-level framework applies to research programs with a research committee and multiple subordinate research projects. The proposed framework is illustrated by examples from the actual research and design process of an interdisciplinary research program investigating the facilitation of diagnostic competences through instructional support in simulations. On a theoretical level, the framework contributes primarily to the literature of EDR by offering a unique dual-level perspective. Moreover, on a practical level, the framework may help by providing recommendations to guide the research and design process in research programs.

Satisfying heterogeneous user needs via innovation toolkits: the case of Apache security software   总被引：3，自引：0，他引：3  

Nikolaus Franke  Eric von Hippel 《Research Policy》2003,32(7):1199-1215

Manufacturers customarily provide only a few product variants to address the average needs of users in the major segments of markets they serve. When user needs are highly heterogeneous, this approach leaves many seriously dissatisfied. One solution is to enable users to modify products on their own using “innovation toolkits.” We explore the effectiveness of this solution in an empirical study of Apache security software. We find high heterogeneity of need in that field, and also find that users modifying their own software to be significantly more satisfied than non-innovating users. We propose that the “user toolkits” solution will be useful in many markets characterized by heterogeneous demand.  相似文献

An Approach to Evaluating the Missing Data Assumptions of the Chain and Post-stratification Equating Methods for the NEAT Design     

Paul W. Holland  Sandip Sinharay  Alina A. von Davier  Ning Han 《Journal of Educational Measurement》2008,45(1):17-43

Two important types of observed score equating (OSE) methods for the non-equivalent groups with Anchor Test (NEAT) design are chain equating (CE) and post-stratification equating (PSE). CE and PSE reflect two distinctly different ways of using the information provided by the anchor test for computing OSE functions. Both types of methods include linear and nonlinear equating functions. In practical situations, it is known that the PSE and CE methods will give different results when the two groups of examinees differ on the anchor test. However, given that both types of methods are justified as OSE methods by making different assumptions about the missing data in the NEAT design, it is difficult to conclude which, if either, of the two is more correct in a particular situation. This study compares the predictions of the PSE and CE assumptions for the missing data using a special data set for which the usually missing data are available. Our results indicate that in an equating setting where the linking function is decidedly non-linear and CE and PSE ought to be different, both sets of predictions are quite similar but those for CE are slightly more accurate .  相似文献   

Arguing to learn and learning to argue: Case studies of how students' argumentation relates to their scientific knowledge     

Claudia von Aufschnaiter  Sibel Erduran  Jonathan Osborne  Shirley Simon 《科学教学研究杂志》2008,45(1):101-131

In this study we investigated junior high school students' processes of argumentation and cognitive development in science and socioscientific lessons. Detailed studies of the relationship between argumentation and the development of scientific knowledge are rare. Using video and audio documents of small group and classroom discussions, the quality and frequency of students' argumentation was analyzed using a schema based on the work of Toulmin ( 1958 ). In parallel, students' development and use of scientific knowledge was also investigated, drawing on a schema for determining the content and level of abstraction of students' meaning‐making. These two complementary analyses enabled an exploration of their impact on each other. The microanalysis of student discourse showed that: (a) when engaging in argumentation students draw on their prior experiences and knowledge; (b) such activity enables students to consolidate their existing knowledge and elaborate their science understanding at relatively high levels of abstraction. The results also suggest that students can acquire a higher quality of argumentation that consists of well‐grounded knowledge with a relatively low level of abstraction. The findings further suggest that the main indicator of whether or not a high quality of argument is likely to be attained is students' familiarity and understanding of the content of the task. The major implication of this work for developing argumentation in the classroom is the need to consider the nature and extent of students' content‐specific experiences and knowledge prior to asking them to engage in argumentation. © 2007 Wiley Periodicals, Inc.

Adrenocortical and psychosocial responses of families in Jordan to the COVID-19 pandemic     

Paul D. Hastings  Lindsey C. Partington  Rana Dajani  Antje von Suchodoletz 《Child development》2021,92(5):e798-e816

This study of 52 predominantly lower income Jordanian and Syrian families with young children (31 girls; M_age = 53.37 months, SD = 3.53) in Jordan began in 2019, before the pandemic. Families were followed to explore stress physiology, family functioning, and mental health over the first 9 months of the pandemic. Mothers reported less adaptive coping and more negative changes to family life in June 2020 when their children had poorer behavioral self-regulation and more behavior problems, and when families had lower income, in 2019. More negative changes to family life predicted greater hair cortisol concentrations in children in June 2020, and more negative changes and less adaptive coping predicted worse child and mother psychosocial adjustment in December 2020.  相似文献   

Investigation of Clinically Significant Change by Severity Level in College Counseling Center Clients     

Brad M. Wolgast  Jill Rader  Deborah Roche  C. Patricia Thompson  F. Christian von Zuben  Allan Goldberg 《Journal of College Counseling》2005,8(2):140-152

The authors investigated the number of sessions necessary for college counseling center clients of different levels of severity of distress at intake to achieve clinically significant change (CS) in therapy. The Outcome Questionnaire‐45 (M. J. Lambert, N. B. Hansen, et al., 1996) was used to categorize 914 clients by severity of distress. Analyses of outcome indicated that clients with less and more severe distress needed 14 and 20 sessions, respectively, for 50% in each group to achieve CS. Implications are discussed.  相似文献   

Pädagogisierung und Systembildung     

Matthias?ProskeEmail author 《Zeitschrift für Erziehungswissenschaft》2002,5(2):279-298

Eine M?glichkeit, das Verh?ltnis von P?dagogik und Gesellschaft zu beschreiben, scheint im Begriff P?dagogisierung zu liegen. In der jüngeren Diskussion lassen sich zwei Konzeptualisierungen dieses Begriffs unterscheiden. P?dagogisierung kann erstens als Transformation sozialer Probleme in p?dagogische Probleme gedeutet werden. Hier wird unterstellt, dass soziale Probleme durch die Einwirkung auf Menschen mit den Mitteln institutionalisierter Erziehung und Bildung zu bearbeiten seien. P?dagogisierung l?sst sich zweitens als Ausdifferenzierung eines symbolisch-kommunikativen Systems innerhalb der Gesellschaft beschreiben. Diese Vorstellung referiert auf die Abl?sung des P?dagogischen von den klassischen Erziehungsinstitutionen. Vor dem Hintergrund dieser Unterscheidung rückt der vorliegende Beitrag in drei Fallstudien den gesellschaftlichen Umgang mit dem so genannten Dritte-Welt-Problem in der Bundesrepublik in das Blickfeld. Die dabei zu beobachtenden Bezugnahmen auf P?dagogik durch die Dritte-Welt-Protestbewegung, das zust?ndige Bundesministerium und Organisationen des Erziehungssystems werden als je unterschiedliche P?dagogisierungsf?lle rekonstruiert. Deren Hybridit?t, d.h. sowohl Eingrenzung wie Entgrenzung, sowohl Bezug des P?dagogischen auf wie auch Abl?sung des P?dagogischen vom institutionalisierten Erziehungssystem, legt es theoretisch nahe, so die These, P?dagogisierungsprozesse in den Zusammenhang von Formbildungen des P?dagogischen einzuordnen.  相似文献   

Competition unleashed: horizontal differentiation in German higher education     

Erhardt  Dominik  von Kotzebue  Alexander 《Tertiary Education and Management》2016,22(4):333-358

Unlike in the US and other western countries, the higher education market in Germany has been sheltered from competition. This changed recently, when a governmental ‘excellence initiative’ began to allocate substantial supplementary funds dependent on higher education institutions’ performance, in 2005. This study is aimed at assessing differentiation tendencies arising from the acute need to become more discernible in an increasingly competitive environment. Based on a content analysis of the full sample of German higher education institutions’ mission statements, we measure the degree of horizontal differentiation among institutions, applying correspondence and cluster analysis techniques. We conclude that horizontal differentiation is not incisive to date, and identify idle potential for creating a more perceptible brand personality.  相似文献
