Individual differences in children's ability to profit from picture adjunct aids

A paired-associate memory task with pictures and words as items was used to categorize fourth graders into four learner types: HH, high picture-high word; HL, high picture-low word; LH, low picture-high word; LL, low picture-low word. Some children in each classification read prose passages with picture adjunct aids; other children read the passages without adjunct aids. Although free recall for the prose passage yielded inconclusive data, a constructed response test for facts in the prose passages revealed significant Aptitude × Treatment interactions, such that poor paired-associate learners (i.e., LLs) profited more than did good paired-associate learners (i.e., HHs) from picture aids on the prose task. The children's standardized reading scores were positively related to memory performance, but good and poor readers did not differ in their ability to profit from picture aids. It was suggested that less-strategic learners, such as those who perform poorly on paired-associate tasks, are more likely to be helped by externally provided mediational aids, while more-strategic learners are more likely to be helped by instructions to generate their own mediational aids.     

Mechanisms of the relation between perinatal problems, early childhood illness, and psychopathology in late childhood and adolescence

Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.     

Masculinity and femininity in twin children: genetic and environmental factors

Genetic and environmental origins of individual differences in masculine and feminine personality attributes were investigated in a sample of 38 monozygotic and 32 dizygotic twin pairs (total N = 140) during pre- and early adolescence. Self-report measures of both masculine and feminine characteristics were obtained for each child using 2 standardized instruments: the Children's Personality Attributes Questionnaire (CPAQ) and the Adolescent Self-Perception Inventory (ASPI). Multivariate biometrical analyses revealed significant genetic influences in all measures, accounting for 20%-48% of the observed variation in each. Environmental influences, which explained the remaining 52%-80% of variance in masculinity and femininity, were apparently specific to each individual and not shared by members of the same twin pair. The results underscore the importance of considering both genetic and environmental factors in gender-role development, particularly in studies of family resemblance.     

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 Use of Computers in the Education of Open University Students with Disabilities

Abstract

In 1988 the Open University is implementing a major new policy on the use of computers in its courses; students taking certain courses will be obliged to have access to a microcomputer. This new policy has many far‐reaching consequences, not least for students who are disabled. In the past most computing in Open University courses has been done by students using terminals in local study centres, linked to the University's mainframe computers. Also, a number of students who are disabled have used computers in their studies, principally for word‐processing written work. By interviewing disabled students who have taken such courses, and surveying other disabled students, it has been possible to anticipate to some extent the likely impact of the home‐computing (HC) policy. Results suggest that for many disabled‐ students the HC policy represents an improvement in their opportunities; now they will be able to study courses involving computers entirely at home. However, a number of problems have also been identified. Hopefully, as many of these have been recognised at an early stage, it will be possible to address them before they affect students directly.     

The relationship between teacher’s autonomy support and students’ autonomy and vitality

Abstract

Within education, some teachers’ interpretation of professionalism emphasizes conformity to the perceived norms of collective associations. Unprofessional behaviour, often equated with ‘unethical’ behaviour, is seen by many to be that which threatens solidarity and loyalty to colleagues. Informal norms typified by casual collegial relations as well as more formal attachments to organized unions or teachers’ federations exert a significant influence on individuals’ behaviour within the group. Professional ethics, in this sense, become concerned primarily with how one relates to colleagues rather than how one fulfils moral responsibilities to students. Qualitative findings from interviews with elementary and secondary school teachers suggest that, as a result of an ethic of collegial loyalty, some teachers experience personal moral and ethical dilemmas that they find difficult to resolve. Some respondents acknowledged that this can enable serious situations to be ignored or ‘covered up’. This paper examines some of the tensions and dilemmas experienced by teachers and raises questions about the ethical adequacy of defining professionalism in terms of inter‐colleague behaviour.     

Development of students’ conceptual thinking by means of video analysis and interactive simulations at technical universities

Video analysis, using the program Tracker (Open Source Physics), in the educational process introduces a new creative method of teaching physics and makes natural sciences more interesting for students. This way of exploring the laws of nature can amaze students because this illustrative and interactive educational software inspires them to think creatively, improves their performance and helps them in studying physics. This paper deals with increasing the key competencies in engineering by analysing real-life situation videos – physical problems – by means of video analysis and the modelling tools using the program Tracker and simulations of physical phenomena from The Physics Education Technology (PhET?) Project (VAS method of problem tasks). The statistical testing using the t-test confirmed the significance of the differences in the knowledge of the experimental and control groups, which were the result of interactive method application.
