Evidence for confounding in computer-based instruction studies: Analyzing the meta-analyses

A thirty percent sample of the computer-based instruction (CBI) studies meta-analyzed by Kulik et al was examined for evidence of confounding. The purpose of the analysis was to explore the validity of competing claims about the contribution of the computer to measured achievement gains found in CBI studies. Some of these claims propose that CBI effects are overestimated and others argue that CBI effects are underestimated. The result of the analysis strongly suggests that achievement gains found in these CBI studies are overestimated and are actually due to the uncontrolled but robust instructional methods embedded in CBI treatments. It is argued that these methods may be delivered by other media with achievement gains comparable to those reported for computers. Construct validity cautions are offered for those who wish to use meta-analytic results as evidence for implementing CBI in schools and for the design of future CBI research.     

Test Takers and the Validity of Score Interpretations

This article argues that test takers are as integral to determining validity of test scores as defining target content and conditioning inferences on test use. A principled sustained attention to how students interact with assessment opportunities is essential, as is a principled sustained evaluation of evidence confirming the validity or calling into question the inferences for individual students. Three innovative assessment systems are highlighted to illustrate where and how the developers might handle diverse test taker needs and learning characteristics. ONPAR measures challenging content using multisemiotic methods and novel item types, designing items to handle multiple profiles so they are accessible for most students. Dynamic Learning Maps has built an innovative network of learning maps, and multiple pathways designed to model how diverse students acquire knowledge. To support their assessments, the National Center and State Collaborative has built an exemplary web of educator resources such as content modules and guides in order to support differentiated learning.     

Behavioral synchronization and affiliation: Dogs exhibit human-like skills

Behavioral synchronization is evolutionary adaptive, fostering social cohesion. In humans, affiliation between partners is associated with a high level of behavioral synchronization; people show increased affiliation towards people who synchronize with them. Surprisingly, until recently, little was known about these phenomena at an interspecific level, which is, however, essential to better understand the respective roles of evolution and ontogeny. After presenting why dog–human dyads are a relevant biological model to study this field of social cognition, we review the recent findings about dog–human behavioral synchronization. We summarize recently published findings on behavioral synchronization and affiliation between dogs and humans. We also review results showing that genetic selection modulates behavioral synchronization propensity in dogs, emphasizing the role of genetic selection on dog’s social behaviors towards humans. Finally, we discuss the possible evolutionary influences and proximate mechanisms of this phenomenon. We conclude that, as in humans, behavioral synchronization acts as a social glue between dogs and humans. After dogs’ ability to use human-directional cues or to produce referential cues towards humans, we evidenced a new human-like social process in the dog, at the interspecfic level with humans.     

Cultural interpretations of the visual meaning of icons and images used in North American web design

This study examines cross‐cultural interpretations of icons and images drawn from US academic websites. Participants from Morocco, Sri Lanka, Turkey, and the USA responded to an online questionnaire containing 18 icons and images representing online functions and information types common on US academic websites. Participants supplied meanings for icons and images and selected a preferred image to represent each of four specific online functions. From three images of professors, participants chose one with whom they would prefer to study. Data were collected at the University of New Mexico, USA; in Internet cafes in the Middle Atlas region and at Al‐Akhawayn University, Morocco; the Open University of Sri Lanka in Nawala, Nugegoda; and at Anadolu University, Turkey. A qualitative analysis examines participants' perspectives and preferences for specific representations and identifies cultural themes in relation to Hofstede's dimensions. Implications for the design of images for cross‐cultural users are discussed.

L'interprétation culturelle de la signification visuelle des icônes et images utilisées dans la conception de sites Web en Amérique du Nord

La présente étude porte sur les interprétations transculturelles des icônes et des images extraites de sites universitaires américains. Des participants venus du Maroc,du Sri Lanka, de Turquie et des Etats Unis, ont répondu à un questionnaire en ligne contenant 18 icônes et images représentant des fonctions en ligne et des modes d'information que l'on trouve couramment sur les sites universitaires américains. Ces participants ont attribué des significations aux icônes et images et sélectionné l'image qu'ils (elles) préféraient pour représenter chacune des quatre fonctions en ligne proposées. A partir de trois images de professeurs,les participants en ont choisi une, celle avec qui ils (elles) préféreraient étudier. Une étude quantitative examine les perspectives des participants et leurs préférences pour une représentation donnée et elle identifie les thèmes culturels par rapport aux dimensions de Hofstede. On étudie les conséquences que cela peut avoir pour la conception d'images destinées à des utilisateurs interculturels.

Kulturelle Interpretationen der visuellen Bedeutung der Symbole und Bilder, die in Nordamerika Web‐Design benutzt werden

Diese Studie untersucht cross‐kulturelle Interpretationen von Symbolen und Bildern, die in akademischen US‐Websites benutzt werden. Teilnehmer aus Marokko, Sri Lanka, der Türkei und den USA bearbeiteten einen Online‐Fragebogen mit 18 Ikonen und Bildern, die Online‐Funktionen und – Informationen auf akademischen US‐Websites gemeinsamen sind. Die Teilnehmer benannten angenommene Bedeutungen der Symbole und Bilder und wählten ein bevorzugtes Bild für jede der vier spezifischen Online‐Funktionen aus. Aus drei Bildern von Professoren wählten die Teilnehmer eines aus, das denjenigen zeigen sollte, mit dem sie es vorziehen würden zu studieren. Eine qualitative Analyse untersucht Perspektiven und Präferenzen der Teilnehmer für bestimmte Vertretungen und Identitäten kultureller Themen in Bezug auf die von Hofstede aufgestellten Dimensionen. Auswirkungen auf die Gestaltung von Bildern für cross‐kulturelle Nutzer werden diskutiert.

The Place of Philosophy in the Training of Teachers: Peters revisited

Abstract

In 1964, Richard Peters examined the place of philosophy in the training of teachers. He considered three things: Why should philosophy of education be included in the training of teachers; What portion of philosophy of education should be included; How should philosophy be taught to those training to be teachers. This article explores the context of the time when Peters set out his views, describes philosophy of education at the London Institute of Education at one period in Peters’ time there, and then discusses the current state of philosophy of education, using New Zealand as an example of opportunities and challenges. Finally, asking whether Peters was nearly right about the place of philosophy in the training of teachers, it is concluded that he was right about its importance but got it wrong about his conception of philosophy.     

DEVELOPING AND EVALUATING AN INTERDISCIPLINARY CLINICAL TEAM TRAINING PROGRAM: LESSONS TAUGHT AND LESSONS LEARNED

The training of clinicians in working together as an interdisciplinary team has received growing support in geriatrics. Most teamwork training programs have focused on group process and development as the core competencies of team practice necessary to improve levels of team functioning. The experience of the Rhode Island Geriatric Education Center (RIGEC) in developing and implementing an ongoing teamwork training program, including the training of several geriatric teams from a variety of health care settings, suggests that additional objectives should include the empowerment of teams for advocacy in rapidly changing health care settings increasingly shaped by economic forces. The lessons learned by RIGEC for the development and implementation of teamwork training include the importance of defining team membership, dealing with the shifting shoals of the health care system, understanding individuals and systems under stress, and redefining the objectives of teamwork training.     

Autonomy: The importance of a scientific theory in education reform

The six national goals established by the National Governors' Association for education reform in the 1990s were conceived by people who had the power to decide what outcomes they wanted based on their own values and priorities. Although it is impossible to avoid questions of values, it is necessary in defining goals for education to consider scientific, explanatory theories about how human beings acquire knowledge and moral values. Jean Piaget's conceptualization of autonomy, in his unusual sense of the term, provides an overall aim for the development of individuals as well as of society, both in the intellectual and the moral realms. Autonomy as the aim of education is based on constructivism, a scientific theory, and would obviate the outdated conceptualization and contradictions among the six national goals.
