The author discusses how pursuing a rhetoric of science has consequences for both our understanding of science and our practice of rhetorical analysis. From a rhetorical perspective, science becomes a persuasive enterprise continuous with other persuasive practices in a culture. And rhetoric itself requires enrichment in three areas to become a better instrument of analysis for scientific texts; it needs to incorporate early modern dialectic, a more flexible stylistics, and an appreciation of the role of visualization in scientific argument.  相似文献

The current research explored the theory of social goal orientation. More specifically, we conducted three studies utilizing six-independent university student samples to evaluate the construct validity of the Social Achievement Goal Orientation Scale (SAGOS; Ryan & Hopkins, 2003), a measure representing the construct of social goal orientation. The purpose of Study 1 was to: (1) compare the three-dimensional (mastery, performance-approach, and performance-avoidance) model of social goal orientation to three theoretically based competing models, (2) examine item functioning, and (3) assess generalizability of the factor structure. The fit of the proposed three-factor model was promising; however, areas of misfit and problematic items were identified. Stronger support for the three-factor structure of goal orientation was found using scores from an abbreviated 13-item SAGOS. In Study 2, item wording was altered slightly to evaluate a revised Social Achievement Goal Scale (SAGS), yet resulted in similar findings. Study 3 examined external validity evidence for the SAGS, garnering some support for the meaning of the scores. Although continued refinement of the SAGOS and SAGS is recommended, the findings help contribute to our general understanding and conceptualization of social goal theory and the role that social goals may play in academic contexts.  相似文献

Summary Coursework is an integral part of the GCSE framework, valued for its motivational qualities and its curricular validity. It is a common perception, widely reported in the national press and educational media, that coursework can be held at least partly accountable for differential performances at GCSE; coursework, it is argued, advantages girls. This article reports on an analysis of data arising from a project which offered an opportunity to study current and post-GCSE students’ perceptions of coursework. The outcomes indicate that, when categorised by their relative levels of attainment, girls’ and boys’ perceptions show limited evidence of homogeneity. In other words, to suggest that girls’ and boys’ perceptions of coursework are a function of gender is a gross over-simplification. Other factors are at play and further, more specific and tailored research is essential if we are to understand how best to optimise the benefits that are claimed for coursework.  相似文献

The present study investigated the extent to which maternal intrusiveness and warmth during play, observed in 579 European American, 412 African American, and 110 more and 131 less acculturated Mexican American low-income families when children were approximately 15 months old, predicted 3 dimensions of the mother-toddler relationship 10 months later. Intrusiveness predicted increases in later child negativity in all 4 groups. Among African Americans only, this association was moderated by maternal warmth. Intrusiveness predicted negative change in child engagement with mothers only in European American families. Finally, near-significant trends suggested that intrusiveness predicted later decreased dyadic mutuality in European American and more acculturated Mexican American families, but not in African American or less acculturated Mexican American families.  相似文献

This study examined the possible selves, goals, and perceptions of “time left” of older adults soon after they entered a life plan community as independent living residents. There has been little research regarding the effect of this life transition on older adults’ self-concept, hopes, and fears. Eighteen residents participated in one-hour personal interviews about their reasons for moving, their possible selves, goals, and perception of time left. Time left was measured in two ways: residents were asked to estimate the number of years they had left and were also asked to mark, on a novel visual analogue measure, how “limited” or “expanded” their time left felt to them. Residents were found to have an average of 6.18 possible selves in total, with more hoped-for possible selves (m = 4.39) than feared possible selves (m = 1.78). The majority of the goals were maintenance goals, followed by self-improvement goals and then avoidance goals. Residents estimated that they would live for 11.64 more years, and the majority reported that this felt like “a lot of time.” Based on their responses to the novel visual analogue measure of time left, two-thirds of the participants reported that their time left felt “expanded” rather than “limited.” Consistent with predictions based on socioemotional selectivity theory, participants with longer subjective life expectancies reported more self-improvement goals and more hoped-for selves. Participants identified more possible selves than documented in previous studies, including almost twice as many hoped-for possible selves.  相似文献

This study examined the association of census level, observational, and parent-reported neighborhood characteristics on the verbal and behavioral competencies of a national sample of Canadian preschoolers (N = 3,350). Children's verbal ability scores were positively associated with residing in neighborhoods with affluent residents and negatively associated with residing in neighborhoods with poor residents and in neighborhoods with low cohesion, even after controlling for family socioeconomic factors. Behavior problem scores were higher when children lived in neighborhoods that had fewer affluent residents, high unemployment rates, and neighborhoods with low cohesion, after controlling for family socioeconomic factors. These findings are discussed in light of neighborhood studies of children in the United States in the mid-1990s.  相似文献

We examined how raters and tasks influence measurement error in writing evaluation and how many raters and tasks are needed to reach a desirable level of .90 and .80 reliabilities for children in Grades 3 and 4. A total of 211 children (102 boys) were administered three tasks in narrative and expository genres, respectively, and their written compositions were evaluated in widely used evaluation methods for developing writers: holistic scoring, productivity, and curriculum-based writing scores. Results showed that 54 and 52% of variance in narrative and expository compositions were attributable to true individual differences in writing. Students’ scores varied largely by tasks (30.44 and 28.61% of variance), but not by raters. To reach the reliability of .90, multiple tasks and raters were needed, and for the reliability of .80, a single rater and multiple tasks were needed. These findings offer important implications about reliably evaluating children’s writing skills, given that writing is typically evaluated by a single task and a single rater in classrooms and even in some state accountability systems.  相似文献

Parenting practices (problem-solving and disciplinary styles) in a sample of 99 young, low-income, African-American multigenerational families were examined, using home-based observations of grandmothers and young mothers (mean age at first birth; 18.3; range = 13.3 to 25.5), interacting separately with 3-year-old children. A risk and resilience approach was applied in studying African-American families' behavior in harsh social contexts, and included a consideration of the role of kin, shared child rearing between mothers and grandmothers, coresidence, and adolescent parenthood. Mothers and grandmothers did not differ in the mean level of the quality of their parenting practices. Similarly, few significant correlations in parenting quality across generations were evident, and these primarily involved negative dimensions of parenting between younger childbearers and grandmothers. No main effect of mothers' age at first birth on mothers' parenting was found. In contrast, there was a main effect of grandmother coresidence on both mothers' and grandmothers' parenting, which was negative. Moreover, the interaction between coresidence and mothers' age at first birth indicated that multigenerational families most likely to provide positive parenting were those where older mothers did not reside with the grandmother. Yet, in families with very young mothers, coresiding grandmothers showed higher quality of parenting than did non-coresiding grandmothers.  相似文献

225 children (ages 4 to 8, 103 girls, 37.5% Mexican-American) participated, reporting who provides support, frequency of receiving different types of support, and satisfaction with support received. These reports were subjected to factor analyses and results did not fit a prior conceptualization. Exploratory factor analyses resulted in a three factor solution that was both more interpretable and the solutions were more similar for reports of frequency of receiving support and satisfaction. A total of six subscale scores were computed, three each for the frequency and the satisfaction items, which were subsequently labelled: informational/emotional, recreational, and practical support. Analyses of the empirically derived subscale scores suggested that young, pre- and early elementary school-aged children responded to questions about their social support in reasonably reliable and valid ways. Significant correlations with indices of perceived competence and acceptance resulted. Remarkably little is known about young children's perceptions of their social worlds, or specifically the nature of support they think is available or that they actually receive. These data suggest that gathering this information from the children themselves is feasible. Ultimately such information should be critical for the design and evaluation of early childhood curricula instructing children about social relations generally, and specifically, who they can turn to for support.  相似文献

Current policy in relation to special needs prioritises early intervention and inclusive education, at least as 'good intentions' This article argues for a paradigmatic shift away from individualist models of learning and disability. The social context of play is emphasised as the crucial arena for realising such good intentions, as long as it is geared to responding to, and developing, the self-determination, control, and identity of young disabled children becoming disabled adults in a disabling society.  相似文献
