Zusammenfassung. Die Erfassung und Umsetzung von Anforderungen an ein Software-Produkt stellt in interdisziplinären Projekten hohe Anforderungen an die Kommunikation zwischen den Projektpartnern. Das Requirements Engineering bietet zwar genügend systematische Ansätze, Anforderungen zu explorieren, zu validieren oder auf Konsistenz zu testen, sodass eine angemessene Umsetzung zum Beispiel durch inkrementelles Prototyping folgen kann. Diese Systematik zielt jedoch auf Entwurf und Implementierung von Software ab. Wir stellen einen Ansatz vor, der eine geeignete Auswahl kommerzieller Werkzeuge schrittweise, also inkrementell nutzt, um in einem interdisziplinären Projekt Anforderungen an webbasierte Studieneinheiten für die klassischen Altertumswissenschaften zu erheben, prototypisch zu gestalten und den Entwicklungsprozess der Studieneinheiten mit Hilfe eines Content Management Systems zu organisieren und zu strukturieren. Hierbei treten bemerkenswerte Parallelen zum klassischen Prototyping auf. Das methodische Vorgehen wird als Ergänzung zur klassischen Anforderungserfassung im Falle nicht-technisch ausgerichteter Projektpartner diskutiert.Eingegangen am 1. Oktober 2002, Angenommen am 16.

ABSTRACT In part 1 of this paper we presented the theory of an integrative geragogy. Integrative geragogy is a basic part of educational gerontology, dealing especially with the oldest of the old, mentally handicapped elderly people, and their potentials. In part 2 the context between theory and practice of an integrative geragogy shall be explained. We will discuss various types of geragogical interventions. First, the binding of personal, social and environmental aspects involved in all types of geragogical interventions are outlined. Second, geragogical implications at the old age have to be legitimated. The several ways of legitimating integrative geragogy will be expounded in order to justify the existence and intervention strategies of this discipline. Third, the paradigm of quality in relation to the integrative geragogy needs to be underlined. 相似文献

We combined independently the word length and word frequency to examine if the difficulty of reading material affects eye movements in readers of German, which has high orthographic regularity, comparing the outcome with previous findings available in other languages. Sixteen carefully selected German-speaking dyslexic children (mean age, 9.5 years) and 16 age-matched controls read aloud four lists, each comprising ten unrelated words. The lists varied orthogonally in word length and word frequency: high-frequency, short; high-frequency, long; low-frequency, short; low-frequency, long. Eye movements were measured using a scanning laser ophthalmoscope (SLO). In dyslexic children, fixation durations and the number of saccades increased both with word length and word frequency. The percentage of regressions was only increased for low-frequency words. Most of these effects were qualitatively similar in the two groups, but stronger in dyslexic children, pointing to a deficient higher-level word processing, especially phonological deficit. The results indicate that reading eye movements in German children are modulated by the degree of difficulty, and orthographic regularity of the language can determine the nature of modulation. The findings suggest that, similar to Italian but unlike English readers, German children prefer indirect sub-lexical strategy of grapheme-phoneme conversion. 相似文献

Concern regarding the secularization of Christian higher education has prompted researchers to investigate the extent that faith and learning is integrated at a faculty level and what factors might predict faculty integration (Lyon, Beaty, Parker, &; Mencken, 2005). This research attempted to replicate Lyon et al.’s (2005) logistic regression model predicting faculty integration of faith using survey responses gathered as part of Phase II of the Council for Christian Colleges &; Universities (CCCU) Denominational Study (Rine, Glanzer, &; Davignon, 2013). Respondents included 2,074 faculty from 55 institutions. The first model used in this study suggested that the most powerful predictors of faculty integration are full-time employment status, earning a degree from an institution that shares the same denominational affiliation, and a match between the faculty member's religious denominational affiliation and the institutional affiliation. A second logistic regression model added faculty academic specialization as a predictor of integration to investigate if that model was a better fit. Results suggested that religion and philosophy instructors are the most likely to integrate faith into their teaching, and professors specializing in computer science, math, and engineering were the least likely. As faculty are considered the primary influence on the integration of faith and learning, existing faculty and institutional administrators concerned with maintaining faith in the classroom may want to consider the contributing factors discussed. 相似文献

To examine the contributions of maternal and paternal age on offspring externalizing and internalizing problems, this study analyzed problem behaviors at age 10–12 years from four Dutch population-based cohorts (N = 32,892) by a multiple informant design. Bayesian evidence synthesis was used to combine results across cohorts with 50% of the data analyzed for discovery and 50% for confirmation. There was evidence of a robust negative linear relation between parental age and externalizing problems as reported by parents. In teacher-reports, this relation was largely explained by parental socio-economic status. Parental age had limited to no association with internalizing problems. Thus, in this large population-based study, either a beneficial or no effect of advanced parenthood on child problem behavior was observed. 相似文献

This article revisits Brian Simon's 1981 judgement that for deep‐seated historical reasons English education lacks a coherent and principled pedagogy. Given that since 1997 the tide of educational centralisation has added teaching methods to those aspects of schooling which the UK government and/or its agencies seek to prescribe, it is appropriate to test the continuing validity of Simon's claim by reference to a major policy initiative in the pedagogical domain: the government's Primary Strategy, published in May 2003. This article defines pedagogy as both the act of teaching and its attendant discourse and postulates three domains of ideas, values and evidence by which both are necessarily framed. It then critically assesses the Primary Strategy's account of some of the components of pedagogy thus defined, notably learning, teaching, curriculum and culture, and the political assumptions which appear to have shaped them. On this basis, the Primary Strategy is found to be ambiguous and possibly dishonest, stylistically demeaning, conceptually weak, evidentially inadequate and culpably ignorant of recent educational history. The article is an extended version of the last in the 2002–2003 Research Lecture series at Cambridge University Faculty of Education, and preserves some of the style of its initial mode of presentation. 相似文献

ABSTRACTIn science education, context-based learning is mostly based on problem-oriented tasks [Gilbert, J. K. (2006). On the nature of “context” in chemical education. International Journal of Science Education, 28(9), 957–976]. Therefore, a relevant question is, how do students integrate the information given in the task into their problem-solving process? The basic assumption is that there is a transition from the situation described in the task to a science model needed to solve the problem [Mestre, J. (2002). Probing adults’ conceptual understanding and transfer of learning via problem posing. Journal of Applied Developmental Psychology, 23(1), 9–50]. The transition needs to be described by parameters of the situation, the science model and the transition process itself. This investigation focuses on the influence of these three elements on the problem-solving process to understand variations in performance [Bennett, J., Lubben, F., & Hogarth, S. (2007). Bringing science to life: A synthesis of the research evidence on the effects of context-based and STS approaches to science teaching. Science Education, 91(3), 347–370]) and the interaction with interest. Despite the large body of research on the mutual influence of context-based problem-solving and interest, research attempting to examine their interplay regarding performance is still lacking. We conducted a hierarchical regression analysis with 178 participants from German high-track schools to investigate three parameters with regard to their influence on affective variables and successful problem-solving: contextualisation of the situation described in the task; the complexity of the scientific model underlying the task; and transparency, which assesses whether and how the learner can identify this model [Löffler, P., & Kauertz, A. (2015). Modellanwendung in kontextualisierten Problemlöseaufgaben [Applying models in contextualised problem solving tasks]. In S. Bernholt (Ed.), Heterogenität und Diversität - Vielfalt der Voraussetzungen im naturwissenschaftlichen Unterricht (Vol. 35, pp. 648–650). Kiel: IPN; Durik, A., & Harackiewicz, J. (2007). Different strokes for different folks: How individual interest moderates the effects of situational factors on task interest. Journal of Educational Psychology, 99(3), 597–610)]. Our findings suggest that these parameters have different effects on how interest is triggered and maintained. Aspects of transparency exhibit small effects on successful problem-solving processes. The results support the assumption that the transition process is the main aspect of context-based problem-solving and can therefore be operationalised as the use of elements of the scientific model in students’ statements. Surprisingly, the usage of such elements cannot be sufficiently explained by pre-knowledge or cognitive abilities. 相似文献
