Consistent evidence that the effect of preschool intervention on cognitive achievement fades with the passage of time has resulted in a search for mediators of preschool. This study investigated factors that play a role in mediating the effects of a government funded Child-Parent Center preschool program. The school adjustment of 266 low-income, mostly Black preschool children and of 125 comparison group children were matched on neighborhood characteristics and were traced from kindergarten through the third year of school (1986-1989). Data were collected from children, parents, and teachers on entering kindergarten cognitive readiness, teacher ratings of socioemotional maturity, parental involvement at home and in school, grade retention, assignment to special education, school mobility and cognitive achievement in reading and mathematics. Results of a latent-factor structural model indicated that preschool influenced later achievement and retention indirectly rather than directly. Four major pathways through which preschool exerted its effect included (1) cognitive readiness, (2) cognitive readiness and teacher ratings of socioemotional maturity, (3) teacher ratings of socioemotional maturity, and (4) parent involvement and school mobility. Cognitive readiness, teacher ratings, and parent involvement also transmitted effects to grade retention. That preschool's influence on later outcomes is largely indirect indicates its dependency on intervening factors in exerting effects. These intervening factors appear to be critical in promoting school success of children at risk.  相似文献

This study built on prior research regarding the effectiveness of the National Center for Research in Early Childhood Education (NCRECE) course by exploring the individual course components. Core aspects of course engagement and performance were described and examined in relation to improvements in the observed quality of teacher–child interactions. Teacher characteristics were also examined as predictors of course engagement and performance. A sample of 150 preschool teachers participated in a semester-long, credit-bearing, college course designed to improve the quality of their emotional, organizational, and instructional interactions with children. Teachers’ participation and performance in the course were high on average. Teachers’ skill level in accurately and specifically explaining other teachers’ instances of effective teacher–child interactions was related to improvements in their own observed teacher–child interactions. Finally, teachers with an early childhood major and those endorsing child-centered beliefs displayed better skills in detecting other teachers’ high-quality interactions with children. Results are discussed in relation to designing more effective early childhood professional development programs.  相似文献

The usual procedure in delayed-matching-to-sample (DMTS) experiments is that the most recently presented sample stimulus is correct on choice tests. The present paper reports two experments in which the first of two samples was always correct. Theories based on trace strength, such as the Roberts and Grant trace strength competition model, predict that such a procedure will yield below chance performance, because on the average the more recently presented stimulus will have the greater trace strength. In contrast, D’Amato and others have proposed that DMTS performance is mediated by a temporal discrimination process and, since either stimulus may act as S+ in a discrimination problem, monkeys should be capable of learning to choose either the secondor the first of two sample stimuli. Performance did not exceed chance in either experiment. The generality of these results is tentatively explored.  相似文献

The purpose of this study was to examine the relations of mothers' and fathers' reported emotion-related practices to parents' and teachers' reports of third-to sixth-grade children's social skills, popularity, and coping, as well as the quantity and quality of children's comforting of an infant. Mothers' problem-focused reactions tended to be positively associated with children's social functioning and coping, whereas maternal minimizing reactions tended to be linked to lower levels of social competence and high levels of avoidant coping. There were few findings for fathers' reactions, although fathers reported fewer problem-focused reactions with socially competent, in contrast to less competent, daughters. Emotion-focused and problem-focused maternal reactions, as well as encouragement of the expression of emotion, were associated with boys' children's comforting behavior, although a moderate level of maternal encouragement of the expression of emotion was associated with quality of girls' comforting.  相似文献

The main thesis of this paper is that the construction and coordination of abstract units is central to mathematical activity in both numerical and geometric settings. Data were gathered from students in grade three through six, with four students being observed over a three year period. A consistent parallel was found in the sophistication of the types of units constructed in a geometric setting (tiling the plane) with their numeric activity. The tiling activity of the students was analyzed for evidence of the construction and coordination of units. Some students constructed rather sophisticated abstract composite units to facilitate their tiling with a particular shape while others had difficulty making a covering. Students who constructed abstract composite units in tiling did so also in adding and subtracting whole numbers. Evidence of unitizing and coordinating the units constructed was associated with advances in mathematical thinking. Unitizing seems to be a fundamental mental operation in coming to act mathematically. As mathematics activities are planned, it is important to provide opportunities for students to construct abstract composite units in both geometric and numeric settings. Emphasis on prescribed procedures such as subtracting with two-digit numerals may inhibit this construction process.  相似文献

The paper describes the use, with primary school maths teachers on an in-service course, of a problem-solving activity in a game format known as the King Alfred's College Maths Game. The game, a variant of a more generalised problem-solving activity, is described in some detail, and the responses of teachers to this are discussed. Use of the game demonstrates to teachers that approaches to problem-solving need to be developed through structured learning experiences which provide material for reflection, and that this reflection requires the teacher to act as questioning agent.  相似文献

The frequency of early childhood education approaches spanning 10 years of publications was investigated. A content analysis of publications (N = 492) from Early Childhood Education Journal was conducted. From a previous content analysis six approaches or search words were identified: Bank Street, Head Start, High/Scope, Montessori, Reggio Emilia, and Waldorf. Overall, the current content analysis demonstrated that the Head Start approach most frequently appeared. The results indicate that approaches vary as to their frequency of appearance and that contributors of Early Childhood Education Journal have investigated, reflected upon, and expanded upon approaches to educating young children to different degrees. This finding may be beneficial to future contributors of Early Childhood Education Journal. In addition, we have provided a brief overview of each approach that early childhood professionals may use to aid parents with their early childhood education enrollment decisions.  相似文献

Each year millions of children are enrolled in center-based childcare. Childcare employees are tasked with handling over half the children’s weekly meals. Proper food handling practices are crucial in mitigating this high-risk population’s risk of foodborne illness. The purpose of this study was to identify childcare food handling employees’ (n?=?278) perceived barriers and motivators to follow recommended food safety practices. Six important barriers and 14 key motivators to following recommended food safety practices were identified. Important barriers pertained to time restraints, workloads, and lack of understanding of the importance of following proper food safety practices. Key motivators were focused on children’s safety, available supplies, communication, and food safety training/information. Employee and facility characteristics were shown to influence perceived importance of barriers and motivators to following food safety practices. Childcare directors should review scheduling and job duties of employees as the majority of identified barriers focused on “work pace” and “time restraints.” Directors should also attempt to increase food safety communication through practical situational training, written food safety policies, and use of food safety signage to increase understanding of the importance of proper food safety practices. Ensuring proper supplies are available is necessary.  相似文献
