Developing teachers' knowledge about assessing English language learners (ELLs) is critical for achieving intended policy outcomes of improving teaching under Race to the Top policy and Common Core State Standards. In addition to teachers' expressed concerns about teaching Common Core State Standards to ELLs in a national survey published in Education Week (Gewertz, 2013), the formation of two assessment consortiums (i.e., Smarter Balanced Assessment Consortium, or SBAC, and Partnership for Assessment of Readiness for College and Careers, or PARCC) indicates the urgency for teachers to demonstrate their assessment knowledge and for schools to provide meaningful professional development opportunities in that area. In this article, we detail the rationale for school-based professional development targeting assessment, especially for new teachers, and outline a proposed procedure for providing such training. 相似文献

Drawing upon research on the visual complexity effect and Dual Coding Theory, this study investigated a) the effects of character properties on, and b) the contribution of individual learner differences to Chinese character acquisition. Participants included 325 Chinese-speaking children in grades 1 through 3 in China. Using a novel character acquisition task, the study extended the scope of previous research by investigating the process of acquiring the meaning of new characters. Results showed that for all three grade-groups, a) characters with radicals and with less visual complexity were easier to acquire than characters without radicals and with greater visual complexity; and b) the effect of radical presence was more pronounced with characters with greater visual complexity. Visual analogical skill made a significant contribution to the acquisition of characters varying in properties, regardless of age. The contribution of radical awareness, however, varied with character properties and age. 相似文献

In the last few decades, changing socioeconomic and family structures have increasingly left children alone without adult supervision. Carefully prepared and limited periods of unsupervised time are not harmful for children. However, long unsupervised periods have harmful effects, particularly for those children at high risk for inattention and problem behaviors. In this study, we examined the influence of unsupervised time on behavior problems by studying a sample of elementary school children at high risk for inattention and problem behaviors. The study analyzed data from the Children's Mental Health Promotion Project, which was conducted in collaboration with education, government, and mental health professionals. The child behavior checklist (CBCL) was administered to assess problem behaviors among first- and fourth-grade children. Multivariate logistic regression analysis was used to evaluate the influence of unsupervised time on children's behavior. A total of 3,270 elementary school children (1,340 first-graders and 1,930 fourth-graders) were available for this study; 1,876 of the 3,270 children (57.4%) reportedly spent a significant amount of time unsupervised during the day. Unsupervised time that exceeded more than 2 h per day increased the risk of delinquency, aggressive behaviors, and somatic complaints, as well as externalizing and internalizing problems. Carefully planned afterschool programming and care should be provided to children at high risk for inattention and problem behaviors. Also, a more comprehensive approach is needed to identify the possible mechanisms by which unsupervised time aggravates behavior problems in children predisposed for these behaviors. 相似文献

This study examined the relationship of family background on students’ academic self-efficacy and the impact of students’ self-efficacy on their career and life success expectations. The study used the national dataset of the Educational Longitudinal Study of 2002 (ELS: 2002), funded by the U.S. Department of Education. Based on a path model, results demonstrated that family background predicted academic self-efficacy positively and students’ career and life success expectations negatively. However, with the mediating influence of academic self-efficacy, family background positively influenced students’ career and life success expectations. School counselors should consider interventions to enhance interactions between parents and students and seek to develop positive perceptions about students’ capabilities and futures. In addition, school counselors need to be knowledgeable about curricula, enrichment classes, summer opportunities, various educational options, and students’ academic and career aspirations for providing better guidance. 相似文献

In this study, we produced a documentary which portrays scientists at work and critically evaluated the use of this film as a teaching tool to help students develop an understanding of the nature of science. The documentary, “Life as a Scientist: People in Love with Caenorhabditis elegans, a Soil Nematode” encompasses the entire process of a scientific investigation by exploring the everyday life of a particular group of scientists. We explored the effectiveness of this documentary in teaching the nature of science by examining the epistemological views of college students toward science before and after viewing. In addition, we collected written responses from the students where they described which aspect of the nature of science they learned from the documentary. The scores of epistemological views toward science increased between the pretest and the posttest (p < 0.01) with the most significant increase being in their views of the role of social negotiation. In the written responses, approximately half of the students suggested that they had learned more about the role which cooperation and collaboration play in the development of scientific knowledge by watching the documentary. The documentary overall provides a valuable instructional context so that students are able to discuss and reflect on various aspects of nature of science within authentic scientific research. 相似文献

In the present study we investigated developmental relations among word reading fluency, listening comprehension, and text reading fluency to reading comprehension in a relatively transparent language, Korean. A total of 98 kindergartners and 170 first graders in Korea were assessed on a series of tasks involving listening comprehension, word reading fluency, text reading fluency, and reading comprehension. Results from multigroup structural equation models showed that text reading fluency was a dissociable construct from word reading fluency for both kindergartners and first graders. In addition, a developmental pattern emerged: listening comprehension was not uniquely related to text reading fluency for first graders, but not for kindergartners, over and above word reading fluency. In addition, text reading fluency was uniquely related to reading comprehension for kindergartners, but not for first graders, after accounting for word reading fluency and listening comprehension. For first graders, listening comprehension dominated the relations. There were no differences in the pattern of relations for skilled and less skilled readers in first grade. Results are discussed from a developmental perspective for reading comprehension component skills including text reading fluency. 相似文献

This case study explored the perceptions of academic stakeholders about the development and delivery of information literacy (IL) programs in four universities, and identified elements necessary to establishing IL credit courses in Vietnamese higher education. The following research questions framed this study: 1) How do library administrators, instruction librarians, and faculty perceive the current implementation of information literacy instruction (ILI) programs for undergraduates studies in universities libraries in Vietnam? 2) What are the challenges to including IL as a credit course in the curriculum as perceived by library administrators, instruction librarians, and faculty? Respondents were purposefully recruited from four universities, including library administrators, instruction librarians, and faculty. Three online surveys were distributed to 537 individuals through Survey Monkey with 149 replies and a final receipt of 133 completed surveys. Interview and focus group data collection included 23 face-to-face interviews and nine focus groups. Findings showed IL is considered the domain of librarians and has not influenced Vietnamese campus culture. IL activities at four university libraries take the form of lectures, workshops, and basic IL skills modules. Few ILI activities are subject discipline-related. Respondents reported challenges to an ILI credit course revolve around the lasting impact of teacher-centered instruction and rote learning, misperceptions about the effect of IL on student learning outcomes, degree of support of IL by academic stakeholders, degree of faculty–librarian collaboration, and scarcity of resources. Recommendations are given for academic librarians in Vietnam implementing ILI programs and considering developing IL credit courses. 相似文献
