Accountability-oriented reforms demand immediate and continual gains on achievement test, for all students, and without diminishing other outcomes or undermining instruction. This paper describes a framework for aligning classroom assessment and external testing with the aim of negotiating these seemingly contradictory goals. The framework varies the sensitivity to instruction and the representations of knowledge across approaches to assessment. Cycles of design- based studies successively refine relationships between a curriculum and the frame that each assessment provides. Doing so, we argue, leverages the unique formative and summative balance across assessments in order to scaffold learning and demonstrate the “consequential” validity of our strategy without compromising curricula, instruction, or the “evidential” validity that warrants their continued use.  相似文献

Serving low-income children from birth to age five and their families, Head Start is a primary venue for identification and intervention in the area of child mental health. However, recent research has demonstrated that the knowledge base regarding prevalence, developmental course, and predictive power of child mental health problems is lacking for young children in general and low-income, diverse populations in particular. Head Start's agency-level data is often discrepant from both national estimates and small, intensive studies of similar populations, perhaps for reasons related to availability of community services and professional staff, as well as concerns about stigmatization. Following on recent expert recommendations, new collaborative Federal initiatives are underway to increase our understanding of the types, trajectories, and treatments of mental health problems affecting the vulnerable children served by Head Start. The paper concludes with a call to action for the field in the area of young children's mental health.  相似文献

Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.  相似文献

The sociocultural context in which children acquire and use everyday mathematics was studied in Brazilian shantytown communities. Children's developing mathematical abilities and use of currency in solving commercial problems were investigated. Interviews with the parents of 105 children from 4 to 14 years of age indicated that, when sent to make purchases at local stands, the problems entailed in the responsibilities parents assigned to children involved greater arithmetical complexity with increasing age. Children's accuracy and strategy use on arithmetic tasks similar to the problems encountered in commercial transactions revealed: ( a ) many children used currency to aid their problem solving; ( b ) with increasing age, currency use declined; and ( c ) children's currency use progressed from global estimates to the mental decomposition and manipulation of currency values. The mathematical complexity of children's commercial transactions correlated significantly with their mathematics performance even when age, grade in school, and years of schooling were statistically controlled The results provide evidence that by adjusting the mathematical complexity of children's commercial transactions, parents facilitate connections between children's developing competence and their everyday activities.  相似文献

Acknowledging the affective in higher education   总被引:1,自引:0,他引:1  
This article argues that we need richer conceptions of students as affective and embodied selves and a clearer theorisation of the role of emotion in educational encounters. These areas are currently under‐researched and under‐theorised in higher education. The first part of the article explores the literature on emotion. The second reports on a case study which aimed to map students' emotional journeys over their first year at university. These data highlight the importance of relationships, students' changing emotions over the year, their perceptions of their academic studies and understandings of life at university. The article concludes that it is important to understand the affective dimension in pedagogic encounters and the lifeworld of students, and that it is possible to do so without a collapse into therapeutic discourses.  相似文献

Because access to new technologies is unequally distributed, there has been considerable debate about the growing gap between the so‐called information‐rich and information‐poor. Such concerns have led to high‐profile information technology policy initiatives in many countries. In Australia, in an attempt to ‘redress the balance between the information rich and poor’ by providing ‘equal access to the World Wide Web’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]), the Australian Council of Trade Unions, Virtual Communities (a computer/software distributor) and Primus (an Internet provider) in late 1999 formed an alliance to offer relatively inexpensive computer and Internet access to union members in order to make ‘technology affordable for all Australians’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]). In this paper, we examine four families, one of which had long‐term Information and Communication Technologies (ICT) access, and three of which took advantage of the Virtual Communities offer to get home computer and Internet access for the first time. We examine their engagement with ICT and suggest that previously disadvantaged family members are not particularly advantaged by their access to ICT.  相似文献

Fourteen behavioral measures were ranked according to their ability to differentiate performances of a wild population of mice from three domestic inbred strains. These “wildness” rankings were then analyzed for their ability to predict genetic and Genotype by Environment interactions. Genetic parameters were derived from analysis of three inbred domestic strains and their three hybrid crosses via the diallel technique of genetic analysis. Genotype by Environment interactions were assessed both as mean differences in stock performances resulting from rearing in a laboratory vs naturalistic environment and as differences in environmental variability within stock genotypes. Behavioral characters ranking high on “wildness” failed to demonstrate any unitary pattern of Genotype by Environment interactions. The diallel genetic analysis revealed many examples of additive variation but relatively few examples of dominant variation. An extremely wide range of interactions occurred between genotype and rearing environments, with “wildness” and “developmental homeostasis” concepts both failing to account for all the observed interactions.  相似文献
