Pairing and gender effects on children’s computer-based learning

This paper reports an experimental study in which one hundred and twenty 11 and 12 year olds worked on a computer based problem solving task couched in an adventure game format. Previous results with this type of task (Blaye, Light, Joiner, & Sheldon, 1991) indicated marked facilitative effects of working in pairs, both on children’s paired performance and on their subsequent individual performance. In this study all children were pre-and post-tested individually. For the intervening practice session subjects were assigned at random to work alone or in single- or mixed-gender pairs. Pairs showed a significant advantage over individuals, but this advantage was not carried over to individual post-test. Gender differences were also attenuated relative to previous results. The findings are interpreted in terms of detailed characteristics of the experimental design (in particular the presence of other children even in the ‘individual’ condition) and reduction of gender stereotyping in the software.     

The Relationship of Self-Concepts to Changes in Cultural Diversity Awareness: Implications for Urban Teacher Educators

This study investigated the relationship between the self-concepts and cultural diversity awareness of 100 European–American pre-service teachers. The Tennessee Self-Concept Scale:2 and the Cultural Diversity Awareness Inventory were administered as a test–retest to ascertain if changes in cultural diversity awareness occurred during a stand-alone multicultural course, and if so were they related to the study participants' pre-test self-concepts. The findings indicate that a statistically significant relationship does exist between total self-concept and total cultural diversity awareness. However, not all five components of self-concept consistently predicted the direction or magnitude of change in the five elements of cultural diversity awareness. These results imply that urban teacher educators should consider both constructs when developing intervention strategies to thwart student resistance to multicultural tenets in stand-alone cultural diversity courses.     

Electrostatic force on the rectangular shield wall of a strip transmission line

For a strip transmission line shielded by rectangular walls,the Green‘s function is helpful to construct the variation expression of the electrostatic energy.Thomson theorem is employed to determine the charge distribution on the strip.The electrostatic force on each side of the rectangular shield wall is achieved by using the principle of virtual work.The results is easy to be obtained by computerized calculation.     

The Rhetoric of Visual Play: An Analysis of Postsubject Voice in New York City

Through an analysis of the street artist Banksy's 2013 residency of New York City, I identify two major rhetorical themes: Images of Discontent and Re-Visions of the City. I argue that the Banksy images exert an influential postsubject voice into the visual discourse of New York City, which I define as a visual articulation that resists traditional markings of identity in favor of visual play. In visual play, elements of the city are turned into toys through a critical orientation towards the urban landscape, postmodern aesthetic codes, participatory rhetoric, and the logics of the virtual. I conclude by arguing that play may offer an effective and transgressive mode of engaging contemporary rhetorical argument, particularly within the materiality of place.     

«Why do you ask?» context and communication in the conservation task

Modifications of conservation tasks designed to increase their ‘social intelligibility’ have frequently been shown to improve young children’s performance. Several studies in this area have involved introducing an emphasis on fairness of distribution, but the significance of this factor has not been independently assessed. Another factor to which attention has recently been drawn concerns the child’s understanding of the experimenter’s intentions in asking the conservation question. Perner (1984) has reported that young children responded more accurately when the question was asked by an experimenter who had not witnessed the earlier stages of the procedure. This paper reports an experiment in which these two factors — the emphasis on fairness and the introduction of a naive experimenter—were manipulated independently. One hundred and twelve 4–6 year olds were divided between four conditions and tested in pairs on a task involving conservation of discontinuous quantity. The results offered clear evidence that emphasising fairness through the device of a competitive game did increase the frequency of correct responses. The introduction of a second experimenter to ask the conservation question also had a significant, if more limited, facilitative effect. Possible social and cognitive processes underlying these results are discussed.
