Can self-report data on deficits in reading and spelling predict spelling disability as defined by psychometric tests?

Questionnaire data concerning spelling and reading self-assessment, habits, and school history were obtained for 79 adults (54 women and 25 men). The items were used to predict affectedness as defined on the basis of psychometric tests. For this purpose, two different discriminant analytical approaches (linear discriminant analysis and hierarchical classification with CART) were compared using a cross-validation design. 86.8–92.6% of the learning sample and 87.5–88% of the cross-validation sample were classified correctly. The CART model was preferred due to a balanced relation of sensitivity and specificity. Our results support the conclusion that self-report data are appropriate to substitute psychometric tests if these cannot be administered.

A Reconsideration of Cognitive Load Theory

Cognitive load theory has been very influential in educational psychology during the last decade in providing guidelines for instructional design. Whereas numerous empirical studies have used it as a theoretical framework, a closer analysis reveals some fundamental conceptual problems within the theory. Various generalizations of empirical findings become questionable because the theory allows different and contradicting possibilities to explain some empirical results. The article investigates these theoretical problems by analyzing the conceptual distinctions between different kinds of cognitive load. It emphasizes that reduction of cognitive load can sometimes impair learning rather than enhancing it. Cognitive load theory is reconsidered both from the perspective of Vygotski’s concept of the zone of proximal development and from the perspective of research on implicit learning. Task performance and learning are considered as related, but nevertheless fundamentally different processes. Conclusions are drawn for the further development of the theory as well as for empirical research and instructional practice.

Lifelong learning and second-order learning objects

Current cultural, social, and economic trends challenge traditional concepts of learning and lifelong learning. This paper draws on the twofold nature of learning in a knowledge society and explores options for technological support. The concept of Second‐Order Learning Objects is introduced as a potential means to foster generative learning. Generative learning goes beyond that what is already known and extends or transforms the socially shared knowledge including its artefacts and practices. According to the notion of individual and social learning as a process of reflective action, the role of strategies and media for reflection and inquiry is stressed. This paper outlines the use of schematically represented strategies for learning and reflection and sketches important features of a pursuant modelling approach.     

‘Analysis of the Evolution of a Science Concept: Macromolecules'‐‐a Case Study to Introduce New Trends in German Teacher‐Training

Summaries

English

This paper describes the philosophy as well as the actual and possible utilization of a model curriculum recently developed in FR Germany. The curriculum contains two parts: one of which deals with teacher training. Here teachers are provided with information, guidelines and procedures, which are to enable them to construct an integrated curriculum—setting out from a special subject within a special discipline. The other part contains a model curriculum for use in schools. It centres around the evolution of the macromolecule concept. Both parts are determined by a philosophy which stresses the importance of the unification of aesthetic and rationalistic elements in science and science education. Generally, it reconsiders the separation between the examining subject, on one side, and nature as the object of examination, on the other side.

The actual process of dissemination and implementation is discussed along with future strategies. It is claimed that the model is confined neither to the specific German situation nor to the topic of the evolution of the specific macromolecule concept.     

Konfigurierungskonzepte für DB-basierte technische Entwurfsanwendungen

Zusammenfassung  . Schwerpunkte einer Datenbank-Unterstützung von technischen Entwurfsanwendungen sind eine geeignete Ablaufkontrolle sowie ein geeignetes Datenmodell. Letzteres mu? Versionen komplexer Objekte verwalten k?nnen. Um aus der Gesamtmenge der in einer Datenbank enthaltenen Versionen konsistente Einheiten (Mengen ‚kompatibler’ Versionen) hervorheben zu k?nnen, werden geeignete Konfigurierungskonzepte ben?tigt. Dieses Papier gibt eine Klassifikation verschiedener DB-bezogener Konfigurierungsans?tze, bewertet diese und begründet damit die Wahl, die im Rahmen des Objekt- und Versionsdatenmodells OVM hinsichtlich des zu unterstützenden Konfigurierungskonzeptes getroffen wurde. Wir werden argumentieren, da? insbesondere die Flexibilit?t, die das gew?hlte Konzept sowohl hinsichtlich der Definition von Konfigurationstypen als auch hinsichtlich des Anlegens von Konfigurationen bietet, zu einer besseren Unterstützung von technischen Entwurfsanwendungen als in bestehenden objekt-orientierten Systemen führt.

Personalization in the public sector: An inventory of organizational and user obstacles towards personalization of electronic services in the public sector

The public sector more and more deploys personalized e-government services. Personalization offers great opportunities to make communication more effective and efficient, to infer and predict citizens' behavior and to even influence behavior. However, some drawbacks must be considered. Important organizational barriers hinder the implementation of personalized e-government services and important user obstacles, such as access, trust, control, and privacy, have to be overcome to make fruitful use of those personalized e-government services.
