Wisconsin's Early Childhood Excellence Initiative was a $15 million public policy effort designed in 2000 to increase child care quality for low-income children. An evaluation revealed significant improvement in classroom quality, the quality of caregiver interaction, and caregivers' beliefs about children following a complex multi-faceted intervention in 28 selected child care centers. The evaluation also revealed higher quality in Centers for Excellence relative to Comparison centers. Research over the past 35 years has demonstrated that high quality early care and education is one of our best hopes for optimizing the long-term developmental outcomes of infants and young children in poverty. Positive results from this evaluation suggest that it may be within the power of state government to raise the quality of early care and education, should the commitment be there to do so.  相似文献

In order to highlight the gender dimension of groupwork I undertook a piece of research in an inner city primary school. My aim was to discover how the group dynamic is affected by altering the gender composition. Consequently I set up a research project in which two groups of primary aged children, one mixed sex, the other girls only, worked on an identical craft, design and technology task. My research findings illuminate the contradictions, complexities and paradox with which issues of gender in the primary school are riven. The findings support the view that the impact of gender on girls is not uniform and consistent across boundaries of race and class but that the three categories are inextricably interwoven. Race and class make significant contributions to any discourse on inequality and although my research is purportedly about gender, the evidence revealed a need for far more investigation into the ways in which gender intersects with race and class.  相似文献

Interactivity is defined by Henri (1992) as a three-step process involving communication of information, a response to this information, and a reply to that first response. It is a key dimension of computer-mediated communication, particularly in the one-on-one communication involved in an electronic mentoring program. This report analyzes the interactivity between pairs of corporate research scientists (mentors) and university biology students (protégés) during two consecutive implementations of an electronic mentoring program. The frequency and structure of the interactions within each pair were examined to provide context: 542 messages were posted among the 20 mentors and 20 protégés. These messages were formed into 5–10 threads per pair, with 3–4 messages per thread, indicating a high level of interactivity (there were more responses posted than independent messages). Mentor–protégé pairs rated as effective by both mentors and protégés posted more messages overall, had well-structured threads, had protégé and mentor postings that were similar in topic coverage and message length, and had little overt “management” behavior by mentors. However, there appears to be no clear recipe for successful interaction. Not only are there a variety of factors at play in developing an online relationship in this context, but mentor–protégé pairs can falter at various stages in the process and in various ways.  相似文献

This study analyses children development of semantic, linguistic, procedural and schematic knowledge in the context of writing arithmetic word problems. 139 children aged between 8 and 12 years old were presented with a task which consisted in writing arithmetic word problems, according to some contraints: words, questions or measures to include in their problems; type of problems to write. Results show the relevance of actual theoritical models of problem solving (Mayer, 1983; Kintsch & Greeno, 1985). Schematic knowledge seem indeed more important than other knowledge in the process of writing arithmetic word problems; semantic knowledge are also used to choose relevant numbers or measures; the roles of linguistic and procedural knowledge seem less evident. Finally, some hypotheses related with the development of mental models of arithmetic word problems are formulated.  相似文献

In 2013, the Local Control Funding Formula (LCFF) was enacted to replace the previous California school finance system. The purpose was to stream various funding sources (e.g., basic revenues, categorical funds, block grants) such that districts could engage in comprehensive planning to support all students. Additional monies designated for English Learners, foster youth, and students living in poverty supplement district funding. We analyzed district Local Control Accountability Plans developed for the 2017–18 school year (n = 50) using qualitative document analysis. Seven coding categories emerged: EL status, personnel, curriculum, instruction, monitoring, counseling, and parent involvement. The second stage of our analysis was in identifying goals, supports, programs, and interventions for English Learners that fell within one of four divisions across two planes. The first is general versus specific, meaning that the approach was intended for all designated groups or for EL students alone. The second plane we used is conventional versus innovative approaches. We saw both conventional and innovative elements across each of the seven categories. Collectively, these findings highlight the strategic ways in which districts are committing to goals and actions in allocating LCFF funding to impact their English Learner populations in meaningful ways.  相似文献

Problem solving is an important yet neglected mathematical skill for students with autism spectrum disorder and intellectual disability (ASD/ID). In addition, the terminology and vocabulary used in mathematical tasks may be unfamiliar to students with ASD/ID. The current study evaluated the effects of modified schema-based instruction (SBI) on the algebra problem solving skills of three middle school students with ASD/ID. Mathematics vocabulary terms were taught using constant time delay. Participants were then taught how to use an iPad that displayed a task analysis with embedded prompts to complete each step of solving the word problems. This study also examined participant’s ability to generalize skills when supports were faded. Results of the multiple probe across participants design showed a functional relation between modified SBI and mathematical problem solving as well as constant time delay and acquisition of mathematics vocabulary terms. Implications for practice and future research are discussed.  相似文献

Teachers' perceptions of the effectiveness of transition classes and the potential relationships between these perceptions and demographic variables were investigated. Seventy-eight first grade teachers from the six New England states completed questionnaires that asked them (a) to rate how children who have participated in transition classes compared in academic achievement, social- emotional development, and attitudes toward school with similar "unready" children who did not participate; (b) to indicate if they would recommend a transition program for their best friends' children; (c) to indicate how they would vote if asked whether their school should continue transition classes; and (d) to supply demographic information. The results clearly indicated that this sample of first grade teachers overwhelmingly supported transition classes and perceived them as beneficial despite the lack of empirical evidence to support these beliefs. No relationships between various background or demographic variables (e.g., certification, degree, membership in professional organizations) and perceptions of effectiveness were found, as evidenced by the support of all types of teachers for transition programs. The findings are attributed to a lack of communication between the primary school practitioners and the early childhood research community.  相似文献

Three experiments were performed to investigate the preference of rats for either free or response-produced food. Rats were trained to free feed in an operant chamber and then to leverpress for food. Subsequently, they were given a choice between continuing to leverpress for food on CRF, FR 2, and FR 10 schedules or free feeding. In three experiments the independent variable was the method of free-food presentation: A fixed free-food dish was used in the first experiment, a movable dish in the second, and a large flat dish in the third experiment. The results of the three experiments were very similar, with most of the rats showing a preference for the free food. This preference increased further when more than one response was required to produce a food pellet. These results contradict any conclusion that rats have a generalized tendency to prefer response-produced to free food but provide no answer to the question of why rats do on occasion respond for food in the presence of free food.  相似文献

Parents and educators concerned with the quality of education in Canadian schools have been subjected to a concerted campaign (through editorials, columns, and letters to the editor in major dailies and magazines, as well as a spate of books with alarmist titles) aimed at convincing them that the lack of adequate testing represents a major shortcoming and a stumbling block to educational reform. Provincewide and nationwide standardized achievement tests are offered as an indispensable tool to understand what works and what does not, to let parents know how schools are doing and how well their children are performing, and to make teachers and school boards accountable. Provincial education authorities are finding it increasingly difficult to resist the pressure, with Ontario the latest to jump on the testing bandwagon. However, although concerns about school curricula and about the best methods for testing student learning and performance are legitimate, the belief that standardized achievement tests are part of the solution to many ills allegedly afflicting our educational system does not stand up to the increasingly clear evidence of the many problems associated with the construction and administration of these tests, as well as the misuse and abuse of test scores. Far from being a panacea, this approach has proved to be fraught with dangers and adverse effects, from a narrowing of the curriculum to overemphasis of routine processes at the expense of higher learning skills, with virtually no empirical support for the purported benefits. With Canadian students facing the risk of being subjected to the same abuses as their U.S. counterparts, this paper reviews recent contributions and attempts to alert educators and policymakers to the serious deficiencies of this type of testing.  相似文献
