Some of the most male-dominated science, technology, engineering and mathematics occupations and degree programmes are found in the world’s most affluent societies. This article assesses whether gender gaps in attitudes follow similarly surprising patterns. Multivariate analysis of eighth-graders’ affinity for mathematics and aspirations for mathematically related jobs in 53 countries shows that the attitudinal gender gap is indeed larger in affluent ‘postmaterialist’ societies. Moreover, both girls and boys view mathematics more negatively in these societies. The authors suggest that cultural ideals of individual self-expression, highly prevalent under conditions of broad-based existential security, operate to reduce girls’ and boys’ interest in pursuits thought to be economically practical but personally non-expressive. Girls may be particularly susceptible to this negative effect, because taken-for-granted cultural beliefs about core female personality traits (and girls’ gendered understandings of their own authentic inner selves) are often at odds with dominant representations of mathematical and technical work.  相似文献

This study examined three basal reading programs published by Heath (1989), Silver Burdett Ginn (1993) and Houghton Mifflin (1993), to determine how frequently logically necessary relationships are expressed in text used by basal readers, and whether direct instruction in making logically necessary inferences accompanies such expressions in basal reader series. The complete contents of the basal readers, from grades one through eight, and all teachers' instructions pertaining to content read by students, were examined for each series. Frequency counts made by independent raters indicated that readers of these three series have a steady and frequent rate of opportunities to make logically necessary inferences, and to observe such inferences being modeled by the text; no significant differences were found between any of the series in the number of such opportunities. We found that while children's reading materials clearly offer a natural context in which logical understanding may be constructed, instructions for teachers in the basal series we examined did not include directly teaching students to use this kind of reasoning in reading comprehension. Suggestions are offered for how such instruction might be integrated with current teaching strategies in inference-making.  相似文献

Relations of regulation and emotionality to social functioning were examined for 77 children followed from early to middle school age. Parents and teachers reported on children's social behavior, emotionality, and regulation, and children engaged in analogue peer conflict situations (i.e., with puppets). High-quality social functioning was predicted by high regulation and low levels of nonconstructive coping, nevatige emotionality, and general emotional intensity. Prediction often was obtained across reporters and time, although prediction was strongest within context (home versus school). Moreover, measures of regulation and emotionality frequently contributed unque variance to the prediction of social functioning. Contemporaneous correlations at age 8–10 were similar to those obtained at age 6–8, and prediction of later social functioning from emotionality and regulation at age 4–6 was similar at ages 6–8 and 8–10.  相似文献

Research suggests that teachers' interactions with preschool-age children have a significant influence on what children learn and the skills they develop. Additional research is needed to systematically determine the types of professional development that can help teachers learn effective teaching practices. This study is part of a larger effort to document the impact of a professional development model in which teachers learn how to implement effective teaching practices operationalized using the CLASS observation measure. A course developed by the National Center for Research on Early Childhood Education (NCRECE) was implemented in three higher education teacher preparation programs. This article describes the process of implementing the course and documents instructor and student perspectives on course delivery, content, and their learning. Results suggest that professional development in the form of a standardized course may be an effective means for presenting content related to language and literacy instruction within the context of information about effective teaching practices. Data from the study also indicate challenges associated with delivering a standardized course within multiple institutions of higher education.  相似文献

This study explored the abilities of 5th, 8th, and 10th graders, and College students to reason logically about what they read. Both students’ metacognitive behavior (looking back at previously read text) and their performance on logical deduction questions were recorded and analyzed in a reading task. Conditional logic premises and deductive questions were embedded in three narratives containing premise information that was factual (True Story), contrary to fact (False Story), or unverifiable via common world knowledge (Neutral Story). The texts and questions were presented one sentence at a time on a computer screen; participants controlled the presentation of sentences. For answering the questions, three response tasks were devised. One task (labeled Generate) required readers to generate their own logical conclusions in response to deduction questions. Two tasks (labeled Valid and Invalid) required readers to evaluate logically valid or logically invalid conclusions drawn by story characters in the texts. Students in early and late adolescence looked back more when asked to evaluate logical conclusions than when asked to generate conclusions on their own; College students’ lookback frequencies were not significantly affected by response task, but were greater overall than those of younger students. With conditional forms requiring an uncertainty response (Affirmed Consequent and Denied Antecedent), readers looked back more when evaluating logically invalid conclusions than when evaluating logically valid ones. Readers of all ages were more likely to agree with story characters’ (valid) uncertain conclusions with the AC and DA forms than they were to disagree with story characters’ (invalid) certain conclusions to these forms. Both lookback frequency and performance on logic questions were lowest when readers were required to reason from contrary to fact premises.  相似文献

This paper reports findings from a study of young children’s views about electric circuits. Twenty‐eight children aged 5 and 6 years were interviewed. They were shown examples of circuits and asked to predict whether they would work and explain why. They were then invited to try out some of the circuit examples or make circuits of their own choosing. Children expressed a variety of views about the connections needed in a circuit, offered different kinds of explanation and showed differing levels of competence in circuit making. The range of responses showed similarities to those of older students found in previous research. The relationship between practical competence, prediction, and explanation was not straightforward. For example, children with similar levels of practical competence made different predictions or offered different kinds of explanation. Analysis of the circuits children chose to construct suggested influences of existing competence and knowledge. In particular, some children tested out circuit examples about which they had been unsure during the interview, while others explored circuit connections more generally. Findings underline the importance of drawing on a variety of evidence in assessing young children’s understandings of electric circuits. They indicate that young children may offer views about electric circuits not unlike those of older children and adults with similar experience. Finally, there was some suggestion that the interview procedure may have acted as an instructive stimulus in helping children to become more conscious of their own views and reflect on their thinking in the light of further evidence.  相似文献

Some literature on elder abuse recommends, and practitioners claim, that there should be better assessment and screening tools. In order to improve the accuracy of measurement instruments, the purpose of this article is threefold: (a) describing the construction of an instrument with formative indicators and the survey design about the sensitive topic of elder abuse, (b) development of an analytic strategy to improve the precision of the measures by (c) evaluating the measurement instrument through quality criteria against outcomes of the instrument. We randomly selected 2,880 home-dwelling older women aged 60 and above from five European Union countries who participated in a survey on elder abuse. Prevalence data on abuse against older women was gathered using a postal (BE, FI, PT), face-to-face (BE, LT), and telephone survey (AT) but using an identical instrument. A table with outcome measures was calculated to evaluate the formative indicators of the measurement instrument, and a decision strategy for item reduction was developed. The results suggest that 12 (35%) of the original 34-indicators instrument can be omitted. The adapted version can provide the same elder abuse prevalence rates (reliability) with the same negative associations in terms of life quality (validity). The results indicate in an applied way how an elder abuse instrument can be evaluated and further developed using formative measures.  相似文献

Theory and Passion in Action Research   总被引:2,自引:2,他引:0  
The starting point for this article is Polanyi's insight that learning involves the personal participation of the knower in taking possession of knowledge, and that this process ‘takes place within a flow of passion’. Somekh pays tribute to Elliott's role in her own intellectual development, as her tutor while she was still a teacher, and later as her colleague. The article focuses on the contribution of the articles published in Educational Action Research, during its first 10 years, under the title of ‘Theoretical Resources’. The contested nature of this title is discussed and illuminated through an exploration of Elliott's writing about teachers' knowledge and the role of both theory and practice in theory generation. Somekh argues for the importance of intellectual engagement with ideas and theories through passionate participation within a ‘personalised and contextualised reality’ – she sees this process as akin to Elliott's notion of action research as a process which ‘problematises the ideas of theorists’.  相似文献

This study examined 164 African American adolescents’ (Mage = 15) daily reports of racial discrimination and parental racial socialization over 21 days. The study examined same-day and previous-day associations of adolescents’ discrimination and socialization experiences with their positive and negative psychological affect. It further explored whether racial socialization messages buffered discrimination’s effects on affect when messages were received during the same day and on the day prior to discrimination. Findings indicated the deleterious effect of racial discrimination (associated with more negative affect) and highlighted the importance of examining youth’s short-term coping in critical developmental years. Findings also showed how messages promote positive youth emotions. However, daily moderating associations differed from prior survey studies, suggesting the importance of examining short-term processes.  相似文献
