Biases in pigeon working memory

The psychophysics and short-term retention of pigeons’ responses to rate of stimulus change were assessed in two experiments, using a symbolic delayed matching-to-sample procedure. In Experiment 1, the birds discriminated between steady and flickering lights. Psychophysical assessments of the discrimination suggested a mix of analogical and categorical strategies. Retention tests revealed a consistent bias to respond to the choice associated with theflickering sample. In Experiment 2, the birds discriminated between different rates of stimulus change (slow vs.fast). Retention tests indicated a bias to respond to the alternative associated with theslow sample. Transfer tests to new stimulus values revealed that the birds processed the stimuli in an absolute, rather than a relational fashion. These findings are related to recent work on biased forgetting in animal working memory experiments.     

Use of social web technologies by international and domestic undergraduate students: implications for internationalising learning and teaching in Australian universities

Much research into the use of online information and communication technologies for the internationalisation of learning and teaching has focused on established web technologies. This paper considers the possible internationalisation implications of existing uses of social software, also known as Web 2.0 technologies, which are now widely available inside and outside of formal education settings. The paper reports on two studies: the first, conducted at a large Australian university, investigated differences between international and domestic undergraduate students’ (n = 1973) use of web‐based technologies and tools; the second investigation reports on interviews with eight Australian and eight Singaporean university students about their use and perceptions of blogs and blogging. The findings from two studies provide new evidence of both cultural similarities and cultural differences in aspects of young university students’ use of social software for communication and content creation. Discussion and conclusions draw out factors to be considered in planning to implement new uses of social software among culturally and linguistically diverse students of the Net Generation, in Australia and more generally.     

An institutional approach to the evaluation of educational technology

While the evaluation of the development, implementation and use of technology in higher education can legitimately be carried out on an individual by individual basis, it is reasonable for institutions to develop their own evaluation approaches to support and guide the evaluation efforts of their staff. This paper outlines an institutional approach that guides the evaluation of educational technology in the Faculty of Medicine, Dentistry and Health Sciences at the University of Melbourne. It proposes roles for an internal evaluator and educational technology practitioners and provides a conceptual framework that guides the evaluation process. Practitioners are supported using micro evaluation guidelines and this process is discussed for two types of evaluation. A discussion of the practical implementation of the framework is supported by the presentation of two evaluation case studies.Une approche institutionnelle d'évaluation de la technologie de l'éducation. Alors que l'évaluation du développement, de la mise en oeuvre et de l'usage de la technologie dans l'enseignement supérieur peut avec légitimité être marquée sur une base d'individu par individu, il est raisonnable que les institutions développent leurs propres approches d'évaluation pour soutenir et guider les efforts d'évaluation de leurs enseignements. Cet article décrit l'approche institutionnelle qui guide l'évaluation de la technologie de l'éducation dans la faculté de médecine, dentologie et de sciences de la santé de l'Université de Melbourne. Il propose des rôles pour une évaluation interne et des praticiens de technologie de l'Education et fournit un cadre conceptuel qui permet de guider les processus d'évaluation. Les praticiens sont aidés par l'emploi de guides de microévaluations et ce processus est discuté pour deux types d'évaluation. Une discussion sur la mise en oeuvre pratique du cadre est illustrée par deux études de cas d'évaluation.Ein institutioneller Ansatz zur Auswertung der Bildungstechnologie. Während die Auswertung der Entwicklung, Umsetzung und die Verwendung von Technologie im Bereich der höheren Bildung mit Recht auf individuellen Basis ausgeführt werden kann, ist es vernünftig, daß Institutionen ihre eigenen Auswertungsansätze entwickeln, um die Auswertungsbemühungen ihres Stabs zu unterstützen und zu leiten. Dieses Papier umreißt einen institutionellen Ansatz zur Auswertung der Nutzung von Bildungstechnologie in der Fakultät für Medizin, Zahnheilkunde und Gesundheitswissenschaften an der Universität von Melbourne. Es beschreibt die Rolle eines internen Auswerters und Bildungstechnikpraktikers und liefert einen begrifflichen Rahmen für den Auswertungsprozeß. Praktiker werden durch Micro-Auswertungsrichtlinien unterstützt. Dieser Prozeß wird für zwei Evaluationstypen erörtert. Die praktische Umsetzung des Rahmens wird anhand zweier Auswertungsfallstudien diskutiert.     

Ein Vorgehensmodell für die Multimedia-Entwicklung mit Autorensystemen

Multimedia-Anwendungen sind interaktive Softwaresysteme und verlangen als solche, mit softwaretechnischen Methoden erstellt zu werden. Sie werden heutzutage in der Regel mit Hilfe von Autorensystemen entwickelt, die eine Ad-hoc-Entwicklung auf Implementierungsniveau unterstützen. Hierdurch und wegen des Fehlens etablierter Vorgehensmodelle für die Multimedia-Softwareentwicklung reduziert sich der Multimedia-Entwicklungsproze? auf die Implementierungsphase. Dies führt zu den in der Softwaretechnik bekannten Problemen wie mangelnder Konzeption und fehlender Dokumentation. Wir stellen in diesem Beitrag ein Vorgehensmodell für die Entwicklung von Multimedia-Anwendungen vor, in dessen Mittelpunkt eine Analyse- und Entwurfsphase im Hinblick auf eine Implementierung der Multimedia-Anwendung mit einem Autorensystem stehen. Ausgehend von einem frameworkbasierten Analysemodell der Anwendung und einem Modell der Realisierungsm?glichkeiten mit einem konkreten Autorensystem wird systematisch ein Implementierungsmodell auf Instanzebene abgeleitet, das als Eingabe für das Autorensystem verwendet wird. Das postulierte Vorgehensmodell wird exemplarisch für das Autorensystem Director am Beispiel der Dom?ne multimedialer Lehr-/Lernanwendungen erl?utert.     

Parents’ attitudes towards inclusive education in day care facilities

ABSTRACT

Parents’ attitudes towards inclusive education in day care facilities in the city and rural district of Osnabrueck in Germany were assessed by conducting a written survey (N?=?809). In the survey, parents indicated their perceptions of advantages and risks of inclusion for children with and without special needs. The interviewed parents perceived more advantages than risks for both groups of children. The results of the assessment varied depending on the kind of child care facility. The paper concludes with recommendations for future research and about how institutions should develop to adequately go about the implementation of inclusive education.

Reassessing the value of university lectures

This paper discusses the role of the lecture in contemporary higher education. Moving beyond the polarised perspectives that characterise recent debates on the subject, it considers both the potential problems and possible pedagogical, practical and social benefits of the lecture as a mode of teaching and learning. Through an examination of scholarly literature on the pedagogical uses of the lecture as well as recent articles on its place in the future of higher education, we outline the key arguments and highlight some of the problems, contradictions and inconsistencies implicit in the debates. Drawing upon the recurring themes in the literature, we identify seven reasons as to why the lecture continues to be valuable in contemporary higher education. However, we also suggest that more innovative approaches to lecturing as well as alternatives to lectures are needed to adapt to a changing educational environment.     

Informal Learning with Technology: The Effects of Self-Constructing Externalizations

ABSTRACT

Especially in the context of technology-enhanced informal learning, it is crucial to understand how to design information sources in such a way that learners are not overwhelmed by the demands of the learning process, but at the same time are engaged in higher order thinking processes. Guidance aids learners in dealing with the demands of a learning process. The authors examined the effects of different levels of guidance provided by an information source. To this end, the effects of a preconstructed externalization are compared to a self-constructed externalization. Thirty-eight students participated in the study. The results revealed no significant differences between the groups with respect to posttest retention. However, performance in application tasks was promoted by the condition associated with a lower level of guidance. This suggests that having learners self-construct an externalization might be a suitable means to elicit learners’ higher order thinking processes in technology-enhanced informal learning.
