Short Cuts and Extended Techniques: Rethinking relations between technology and educational theory

Building upon a recent call to renew actor-network theory (ANT) for educational research, this article reconsiders relations between technology and educational theory. Taking cues from actor-network theorists, this discussion considers the technologically-mediated networks in which learning actors are situated, acted upon, and acting, and traces the novel positions of creative capacity and participation that emerging media may enable. Whereas traditional theories of educational technology tend to focus on the harmonization of new technologies with extant curricular goals and educational practices, an educational theory of technology looks to novel forms of technologically-mediated learning experience—from production pedagogies to role play in the virtual—to make visible the surprising relations, techniques, and opportunities that emerging media, and their attendant social contexts, may offer educational research.     

Effiziente Informationssuche im Internet mit Hilfe mobiler Programme

Zusammenfassung.   Die Bereitstellung eines pr?zisen, effizienten und m?glichst vollst?ndigen Zugriffs auf aktuelle Informationen im Internet ist eine grundlegende Voraussetzung für die Weiterentwicklung des elektronischen Handels. Dieser Beitrag zeigt, wie themenspezifische Suchwerkzeuge mit Hilfe mobiler Programme eine solche Bereitstellung leisten k?nnen. Der vorgestellte Ansatz wird durch messdaten-basierte Simulationen sowie anhand einer Fallstudie evaluiert. Eingegangen am 15. Dezember 1999 / Angenommen am 10. April 2000     

A Multifactor Approach to Candidate Image

Decades of communication research have demonstrated that political candidate images are important predictors of electoral success and that campaign communication influences these image perceptions. However, questions remain about the relative importance of various facets of candidate image, how electoral context and partisanship influence the salience of these facets, and whether privileged classes enjoy presumption in image facets that reinforce their dominant position in politics. These questions require a new approach to image research. We propose a multifactor approach that explores the relative importance of six image traits: character, intelligence, leadership, benevolence, homophily, and charm. The benefits of this approach are illustrated through application to two electoral contexts, the 2012 U.S. presidential election and the 2014 U.S. midterm elections.     

Meta-analytic evidence for the persuasive effect of narratives on beliefs,attitudes, intentions,and behaviors

Although narratives are often credited with the capacity to change opinions, empirical tests of this prediction have produced mixed results. To provide a more precise test of narrative's effect on beliefs, attitudes, intentions, and behaviors, we performed meta-analyses on studies that evaluated narrative's persuasive influence on these outcomes. Results suggested positive relationships between exposure to a narrative and narrative-consistent beliefs (k?=?37; N?=?7,376; r?=?.17), attitudes (k?=?40; N?=?7,132; r?=?.19), intentions (k?=?28; N?=?5,211; r?=?.17), and behaviors (k?=?5; N?=?978; r?=?.23). Moderator analyses on the effect of fictionality yielded mixed results. Neither medium of presentation nor research design influenced the magnitude of the narrative-persuasion relationship. However, results suggested the presence of unidentified moderators.     

EDUCATION,TASK MEANINGFULNESS,AND COGNITIVE PERFORMANCE IN YOUNG‐OLD AND OLD‐OLD ADULTS

Previous research has indicated that when tasks are made more meaningful, the performance of the elderly generally improves. A closer look, however, reveals that improvement occurs mostly for educationally disadvantaged elderly, highly educated older adults not benefiting differentially from meaningful material. Consequently, the present study compared performance of high‐ and low‐education adults on traditional and meaningful space and reasoning measures. A total of 246 male and female volunteers were divided into subgroups by age (53‐65 and 70‐78 years) and by education (high and low). Separate analyses of variance for reasoning and space revealed main effects for education and age on both abilities. In addition, main effects for test and sex, and a significant age by test interaction were found for space, with the performance differential between the familiar and traditional tests being much greater for the young‐old group. A trend for an education X age X test X sex interaction was found for reasoning, as expected, with low education, young‐old men doing more poorly on the traditional form. Suggestions for future related research are discussed.
