What Is a Reference Source?

Reference is the balance of employing a process to use materials to locate information. A key feature of teaching reference is to help students understand what a reference source is. This column introduces the dilemma of that seemingly easy task. It includes examples of course assignments to aid in that effort.     

The 2003 Benjamin Franklin medal in electrical engineering presented to Bishnu S. Atal

Dr. Atal was chosen for his fundamental contributions to speech coding in digital cellular telephony—specifically for pioneering work in linear predictive coding (LPC) and use of analysis-by-synthesis leading to multi-pulse excited linear predictive coding and code excited linear predictive coding (CELP). These are the basis of time-division and code-division cellular systems (TDMA & CDMA), the Nextel system, and the global system for mobile communications (GSM).     

Reading-Writing Connections: the Importance of Interactive Discourse

Margaret Meek (1988) has described how children borrow ideas from literature through ‘unteachable’ lessons. In this article, I examine how children's written work is enhanced through ‘teachable’ lessons, where the teacher draws attention explicitly to aspects of literary texts and where children explore and evaluate literature through group reading and discussion. The ways in which children transfer the knowledge of literary devices, gained through group discussion, to their own writing are examined. The relationship between group evaluations of texts and children's writing development is explored with reference to the work of Year 6 children. This illustrates how critical reading and group discussion can raise primary children's metalinguistic awareness and develop their understanding of the stylistic features of narrative texts.     

Psychosocial Adjustment Over a Two–Year Period in Children Referred for Learning Problems: Risk,Resilience, and Adaptation

Children with learning difficulties have an increased prevalence of psychosocial adjustment problems. We hypothesized that within the context of a risk and resilience model contextual variables influence adjustment, over and above any effects of academic performance. The Behavior Assessment System for Children (BASC) was used to evaluate the relationship between psychosocial adjustment, changes in academic skills, and contextual factors longitudinally over a two–year period in 100 children (ages 7 to 11) referred for learning problems. Although there was little improvement in academic skills, contextual factors contributed to observed psychosocial outcome. Different factors were salient for parents, teachers, and children. Context–derived vulnerability and protective factors can be important determinants of adjustment in children with learning problems, even though the academic difficulties can remain chronic.     

Bourdieu on Education and Social and Cultural Reproduction

Bourdieu's work has attracted considerable interest and, not withstanding criticism of his style and obscure theoretical formulations, has introduced some powerful concepts into social theory. This paper examines Bourdieu's contribution to the sociology of education and especially his account of socially differentiated educational attainment. Particular attention is given to issues of structure, agency and habitus, the cultural autonomy of the school, arbitrary and necessary school cultures, and the distinction between primary and secondary effects on educational differences. Some specific criticisms, for example Elster's charge of a double account of domination, are also addressed. Bourdieu's concentration on habitus as the most significant generator of practice is held to be a theory of socialisation and the paper examines the nature of the explanation of social practice provided by such theories. The argument concludes with a plea for critical tolerance with respect to Bourdieu's work but with a suggestion that his account of socially differentiated educational attainment in terms of habitus is finally inadequate.     

The influence of group size on children's competitive behavior

The present research was designed to test the hypothesis that children would compete more in tetrads than in dyads. Twenty-two pairs of male and 14 pairs of female target children (N = 72) played a competitive game in both tetrads and dyads. Consistent with the hypothesis, male target children competed more in tetrads than in dyads. This hypothesis was not supported for females, however. Analyses of the dynamics of tetrads and dyads further demonstrated that based on a global measure of smiling, the emotional atmosphere was less positive in tetrads than in dyads. The causes and consequences of interaction in different sized social groups are discussed.
