Place value notation is essential to mathematics learning. This study examined young children's (4‐ to 6‐year‐olds, N = 172) understanding of place value prior to explicit schooling by asking them write spoken numbers (e.g., “six hundred and forty‐two”). Children's attempts often consisted of “expansions” in which the proper digits were written in order but with 0s or other insertions marking place (e.g., “600402” or “610042”). This partial knowledge increased with age. Gender differences were also observed with older boys more likely than older girls to produce the conventional form (e.g., 642). Potential experiences contributing to expanded number writing and the observed gender differences are discussed. 相似文献

The term technology-enhanced learning (TEL) is used to describe the application of information and communication technologies to teaching and learning. Explicit statements about what the term is understood to mean are rare and it is not evident that a shared understanding has been developed in higher education of what constitutes an enhancement of the student learning experience. This article presents a critical review and assessment of how TEL is interpreted in recent literature. It examines the purpose of technology interventions, the approaches adopted to demonstrate the role of technology in enhancing the learning experience, differing ways in which enhancement is conceived and the use of various forms evidence to substantiate claims about TEL. Thematic analysis enabled categories to be developed and relationships explored between the aims of TEL interventions, the evidence presented, and the ways in which enhancement is conceived. 相似文献

When introducing and implementing a new technology for science teachers within a school district, we must consider not only the end users but also the roles and influence district personnel have on the eventual appropriation of that technology. School districts are, by their nature, complex systems with multiple individuals at different levels in the organization who are involved in supporting and providing instruction. Varying levels of support for new technologies between district coordinators and teachers can sometimes lead to counterintuitive outcomes. In this article, we examine the role of the district science coordinator in five school districts that participated in the implementation of an online resource discovery and sharing tool for Earth science teachers. Using a qualitative approach, we conducted and coded interviews with district coordinators and teachers to examine the varied responsibilities associated with the district coordinator and to infer the relationships that were developed and perceived by teachers. We then examine and discuss two cases that illustrate how those relationships could have influenced how the tool was adopted and used to differing degrees in the two districts. Specifically, the district that had high support for online resource use from its coordinator appeared to have the lowest level of tool use, and the district with much less visible support from its coordinator had the highest level of tool use. We explain this difference in terms of how the coordinator’s promotion of teacher autonomy took distinctly different forms at those two districts. 相似文献

In this study, associations between health-care providers (HCPs) discussing diet with their pregnant patients and patient dietary behavior were assessed in addition to factors related to HCPs discussing diet with their patients. Questionnaires were completed by 237 pregnant women and 31 HCPs at 12 obstetrics–gynecology clinics across the United States. Patients provided versus those not provided dietary counseling by their HCP were more likely (OR = 2.17, 95%; CI = 0.75–6.25) to engage in healthy dietary practices. HCPs that discussed multiple health behaviors were nearly four times more likely to discuss diet with their pregnant patients compared with HCP who did not discuss other health behaviors (OR = 3.67, 95%; CI = 1.10–12.28). This study indicates that HCP education can positively impact dietary behaviors of their pregnant patients. 相似文献

Information literacy curriculum for third-year medical students at Northwestern University has evolved over several years under the guidance of librarians at the Galter Health Sciences Library. Starting as a series of rotation-specific information resource overviews, initial evaluation and feedback led to the curriculum being developed to include more focused and interactive clinical information sessions with a quiz-based assessment. Future enhancements will include web-based self-directed learning using online tutorials, additional search exercises that mimic the on-the-go clinical environment, and better assessment of the curriculum's impact on students' information literacy and clinical search skills. 相似文献

Usability Testing for e-Resource Discovery: How Students Find and Choose e-Resources Using Library Web Sites 总被引:1,自引:0,他引:1
In early 2010, library staff at Bowling Green State University (BGSU) in Ohio designed and conducted a usability study of key parts of the library web site, focusing on the web pages generated by the library's electronic resources management system (ERM) that list and describe the library's databases. The goal was to discover how users find and choose e-resources and identify ways the library could improve access to e-resources through its web site. This article outlines the usability study conducted at BGSU, presents its conclusions about how students at BGSU find and choose databases, contextualizes these findings with other current research about user behavior, and makes recommendations for increasing student use of library e-resources. 相似文献

The use of technology for teaching and learning is now widespread, but its educational effectiveness is still open to question. This mixed-method study explores educational practices with technology in higher education. It examines what forms of evidence (if any) have influenced teachers' practices. It comprises a literature review, a questionnaire and interviews. A framework was used to analyse a wide range of literature. The questionnaires were analysed using content analysis and the interviews were analysed using inductive thematic analysis. Findings suggest that evidence has partial influence upon practice with practitioners preferring to consult colleagues and academic developers. The study underscored the difficulty in defining and evaluating evidence, highlighting ontological and epistemological issues. The academic developer's role appears to be key in mediating evidence for practitioners. 相似文献

Following the 1994 democratic elections, education policy in South Africa has moved from collective and transformational priorities, salient during the 1980s period of resistance, to a centrist and pro‐human capital position. While the democratic movement talked much about core reforms in the social relations inside classrooms, the new Government of National Unity is focusing on system‐wide rationalisation (including a unified qualifications scheme), developing management information and incrementally changing spending patterns. School quality is being addressed but with much less emphasis on democratising social relations and changing the character of classrooms than anticipated during die years of resistance. This paper describes this dramatic shift in education policy priorities, focusing on central government and two contrasting provinces. It employs two theoretical frameworks ‐‐ political economy and institutional theory ‐‐ to explain the causes and forms of this new set of policy priorities. 相似文献
