This article reports the results of research to determine if a significant interactive effect exists between students' lingual background (English as a primary language [EPL] versus English as a secondary language [ESL]) and question format on students' examination scores. Students were administered examinations made up of four subtests covering the same subject matter. The subtests were composed of four question formats: multiple choice quantitative, multiple choice theoretical, open-ended quantitative, and open-ended essay questions. Based on analysis of variance and analysis of covariance, significant differences were observed between EPL and ESL students depending on the type of question on the examination.  相似文献

In a widely cited study, Matas, Arend, and Sroufe showed that mother-toddler interaction during problem solving at age 2 years was related to the child's prior attachment security. The current study asked (1) whether an independent laboratory could replicate this attachment finding, and (2) whether problem-solving interactions relate to mother-child interactions observed at home and to child temperament measured at 6, 13, and 24 months. Replicating Matas et al., secure dyads worked more competently, and mothers showed better quality of assistance and supportive presence. Mother-child home interaction also predicted problem solving: positive involvement at home predicted effective, unconflicted problem solving. Negative control at home did not predict problem-solving interaction. Unadaptable temperament was generally related to dependency in problem solving. Several patterns of correlations appeared to be mediated by sex of child, e.g., difficult temperament in boys predicted more effective, unconflicted problem solving, while for girls it predicted more conflict.  相似文献

Research Findings: Recent research has validated the power of evidence-based preschool interventions to improve teaching quality and promote child school readiness when implemented in the context of research trials. However, very rarely are follow-up assessments conducted with teachers in order to evaluate the maintenance of improved teaching quality or sustained use of evidence-based curriculum components after the intervention trial. In the current study, we collected follow-up assessments of teachers 1 year after their involvement in the REDI (REsearch-based, Developmentally Informed) research trial to evaluate the extent to which intervention teachers continued to implement the REDI curriculum components with high quality and to explore possible preintervention predictors of sustained implementation. In addition, we conducted classroom observations to determine whether general improvements in the teaching quality of intervention teachers (relative to control group teachers) were sustained. Results indicated sustained high-quality implementation of some curriculum components (the Promoting Alternative THinking Strategies curriculum) but decreased implementation of other components (the language/literacy components). Sustained intervention effects were evident on most aspects of general teaching quality targeted by the intervention. Practice or Policy: Implications for practice and policy are discussed.  相似文献

The status of research on women and communication   总被引:2,自引:1,他引:2  
The purpose of this essay is to survey and summarize the research on women, gender, and sex differences that has been published in speech communication journals. Five categories of research emerged from this survey: historical treatments of women, sex differences, images of women in the media, education and pedagogy, and surveys and integrative works. While future research is needed to fill in the gaps made evident by this survey of literature, perhaps more important is to begin to question and investigate the assumptions underlying current research about women.  相似文献

In this study, five elementary teachers and a university researcher developed and implemented problem‐based learning (PBL) experiences in the context of science teaching and learning. Collaborative inquiry was adopted as a methodology, while a variety of qualitative methods were used to examine the engagement and development of teachers’ pedagogical content knowledge (PCK). A PCK model is used as a framework to examine teachers’ professional knowledge growth in areas such as orientations to teaching science, knowledge of science curriculum, knowledge of students’ understanding of science, knowledge of assessment, and knowledge of instructional strategies. Implications for how teachers may be supported when adopting instructional innovations are discussed.  相似文献

This study examines the nature of teacher participation in the context of a video club. Video clubs are professional development meetings in which teachers watch and discuss excerpts of video from their classrooms. In this study, I adopt a situative perspective to examine how teachers develop in their participation to accomplish the goals of the video club. In particular, I examine the roles participants play and explore teachers' participation in four roles that correspond with key goals of the video club. Analysis revealed that teachers' participation shifted in qualitatively different ways over time, with the teachers coming to prompt the group to discuss student mathematical thinking, to propose a variety of interpretations of student ideas, to build on one another's ideas, and to challenge one another's thinking in order to advance the group's conversations. This analysis suggests that the group learned how to participate in roles central to accomplishing the goals of the video club. Studying teacher learning through a lens of participation provides insight into the ways in which teachers coordinate themselves to engage with the goals of professional development and has implications for designing professional development that helps teachers develop practices for teaching mathematics for understanding.  相似文献

This article consists of a case study and policy analysis of a conflict between two federal mandates that arose during the initial implementation of the No Child Left Behind Act in 2002 in a southern school system, Richmond County, Georgia. The first part of the article documents the conflict, drawing on primary source documents and interviews with the school superintendent and school board attorney. A U.S. District court judge ruled that the 1972 court order that had mandated county-wide school desegregation was in conflict with No Child Left Behind's public school transfer policy and granted the county a one-year delay so that the school system could study the policy's likely effects. The U.S. Department of Education's response to the judge's ruling instigated a situation that led to a federal-local political disagreement, whose origins and resolution are described. In the article's second section, the author places these events into broader historical perspective, arguing that they reveal how federal policy in elementary and secondary education has shifted during the intervening decades since the Elementary and Secondary Education Act's enactment in 1965. The case highlights the changing federal-district relationship, the equitable implementation of the No Child Left Behind public school choice provision, and the nature of federal authority in education policy, and how it is currently being exercised by the Bush administration.  相似文献

Health is associated with academic success. Universal, web-based interventions to reduce risks associated with alcohol and other drug use have been found to be effective at changing four-year college students’ health behaviors. An online health program may also be well-suited to a community college population, as it can reach students off campus and can be accessed at times that are convenient for students. The purpose of the current paper is to report the results of a community college student evaluation of a fully-developed, online health risk reduction program. One hundred and thirty four students evaluated the program. Students perceived the program to be successful at addressing college health and wellness issues, and they considered it a tool that could help students make a healthy adjustment to college. A universal, online, health-risk reduction program may have the potential to be a useful component of a community college's overall prevention strategy.  相似文献

This study replicates research on the efficacy of a repeated reading intervention with word-level instruction for students in Grades 2 and 3 with low to moderate fluency skills, examines differences between treatment implementers, and tests unique contributions of treatment-related variables on outcomes. Students from 13 schools were randomly assigned to dyads; dyads were randomly assigned to treatment or control conditions. Schools were matched into treatment implementer groups (teachers or paraeducators) at study onset. Tutoring occurred during school hours for 15 weeks (M = 25.5 hr). Multilevel model results showed treatment students (n = 98) gained more than controls (n = 104) on measures of letter-sound knowledge (d = .41), fluency (d = .37–.38), and comprehension (d = .30–.31); students tutored by teachers gained more than their paraeducator-tutored peers on word reading and fluency. Finally, dyads tutored with greater fidelity gained more in word reading and fluency; dyads that read more complex words in their texts gained less on letter-sounds, fluency, and comprehension.  相似文献
