The 2000 US census was the first to allow respondents to check more than one race/ethnic response for their identity. About 6.8 million Americans did so, and a disproportionate percentage of them were children under age 18 years old. The purpose of this article is to examine the extent to which this change is reflected in contemporary child psychology textbooks. Twelve books were examined to determine whether they covered multiracial and multiethnic children. Results of this study showed that only two of these books addressed issues related to the healthy development of multiracial/multiethnic children in any detail; and, while several used terms such as biracial and bicultural, these terms were always used to describe single-race minority children living in a majority context. The discussion section covers possible reasons for this omission.  相似文献

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)—extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach that included visuals, bilingual definitions, examples, spelling, and partner-talk about the words’ meaning. Words assigned to the embedded condition were taught solely through brief definitions to embedded text, writing activities, and songs. In the control condition students heard the target words read aloud during shared interactive reading but without definitions or direct instruction. The study also explored the interaction between instructional condition and word type. Four types of words—abstract cognates, abstract noncognates, concrete cognates, and concrete noncognates—were randomly assigned to each condition. Nine teachers in four schools and 187 second-grade ELs participated in this within-subjects intervention, which took place in transitional bilingual classrooms. Findings indicated that across all word types, both extended and embedded instruction were more effective than the control condition in helping ELs acquire vocabulary. Findings also indicated that extended instruction was more effective then embedded instruction for all word types except concrete cognates suggesting that these young Spanish-speaking ELs were advantaged by word knowledge in their home language. Finally, while embedded instruction was less effective than extended instruction, it was much more effective than a control condition. Embedded instruction takes significantly less preparation and instructional time than extended instruction, offering teachers a practical way to teach more vocabulary to ELs.  相似文献

Citation analysis is a valuable method for tracking the growth and transmission of scientific knowledge. In criminology and criminal justice, such analyses tend to be focused on “classic” works or on highly cited scholars over many years. As an alternative approach, we focus on work that has been cited rather quickly – what we term the “early onset” of impact. In doing so, we identified 221 of the most highly cited peer-reviewed articles, authored by 480 scholars, which were published in criminology and criminal justice journals between 2010 and 2015. Analyses reveal wide variation in substantive topics and methodological approaches, as well as a substantial gender gap with respect to authorship. Additional analyses provide insight into both journal and institutional/program prestige. We conclude with directions for future research and stress the importance of tracking over time articles that appear to be off to an early start with respect to scholarly impact.  相似文献

Practical independent research projects (IRPs) are a feature of school science in a number of countries. To assess the impact of IRPs on students, a systematic review of the literature was undertaken. Thirty-nine papers met the review inclusion criteria, reporting on work from twelve countries. The review indicates that IRPs are often associated with wider initiatives such as authentic science, problem-based learning, and project-based learning. There is considerable variability in the nature of IRP work in relation to focus, models of provision, assessment, the involvement of external partners such as universities and employers, and funding, and this diversity affects judgements on the quality of the evidence base on impact. The majority of the research reviewed explored areas such as conceptual understanding, motivation to study science once it is no longer compulsory and attitudes to science, and the development of practical skills. Benefits were identified in relation to the learning of science ideas, affective responses to science, views of pursuing careers involving science, and development of a range of skills. Studies focusing on traditionally under-represented groups indicated that such students felt more positive about science as a result of undertaking IRPs. The review findings indicate that further work is needed to enhance the quality of the available evidence, to consider the ways in which IRPs can be validly assessed, to explore more fully the potential benefits for traditionally under-represented groups, and to explore more fully the potential longer-term benefits of participation in IRPs at high school level.  相似文献

The robustness of the effect of precise elaborations on memory and the relationship of these effects to metacognitions about learning was investigated in two studies. Twenty-six naive experimenters administered prepared tasks to 130 subjects. Participants rated the comprehensibility of each sentence as it was read. An unexpected cued-recall test with a confidence rating for each answer given was administered, followed by rating the ease of learning the types of items used in three treatments: precisely elaborated, imprecisely elaborated, and unelaborated base sentences. Both studies resulted in very similar findings: Memory for precise elaborations was 50% greater than for either imprecisely elaborated or unelaborated statements. Comprehension ratings of the three sets of statements were not significantly different. Confidence ratings of correctly answered items were significantly higher than of incorrectly answered items.  相似文献

ABSTRACT

Using the interlocking concepts of power, knowledge and discourse, this article focuses on how counter normative sexualities are discursively constructed in the sexuality education classroom and with what effects. Drawing on in-depth interviews with teachers and classroom observation, the evidence highlights the presence of specific discourses about the teaching and learning of sexuality diversity. First, while many teachers argued for the inclusion of counter-normative sexualities, in their teaching and responses they privileged heterosexuality as legitimate and natural and same-sex sexualities as deviant and Other. Second, teachers’ discourses construct queer youth not only as innocent and childlike but also as hypersexual and rebellious – requiring discipline and intervention. These constructions link closely to discourses of pity and tolerance, or blame when counter-normative sexualities were expressed. Finally, despite heterosexuality being privileged in the classroom, teachers’ and pupils’ questions about gender and sexuality diversity suggest the need for a more defined and inclusive curriculum sexuality education curriculum. Findings justify concern about how counter-normative sexualities are addressed in the sexuality education classroom and advocate for improvement in teaching and learning about counter-normative sexualities in South African secondary education.  相似文献

The abandonment of a commitment to the achievement of social democratic consensus in the Thatcherite project and the emphasis on individualism and the market means that a new source of cultural hegemony has to be sought. It is being attempted by the inculcation of a particular form of nationalism using the family and schools as a vehicle. The exact parameters of what constitutes Britishness are achieved by the marginalization of groups and movements that threaten the particular Thatcherite model of the nation and the imposition of a limited, and racist, model of culture. Within education a struggle is developing over content as the government seeks to impose a National Curriculum that reflects its ideology while structural changes hasten the commodification of education. Both the curriculum and structural changes are likely to have a detrimental effect on black and working-class pupils.  相似文献
