This study examined the extent to which fifth-grade students participate in online argumentation and the argument patterns they produced about the inquiry-based investigations completed using the Science Writing Heuristic approach in their science classes. One hundred twenty-nine students from five classes of two teachers in a Midwestern public school completed two inquiry-based investigation units, one per semester, followed by asynchronous online discussions using the Moodle forum. Among the 129 students, 107 students produced 739 notes in the plant investigation online discussion and 111 students produced 686 notes in the human health investigation online discussion. Results indicate that students were actively engaged in the online discussions about inquiry investigations with comments being focused on providing more evidence and backing for claims and negotiating evidence in both investigations. The students also engaged in challenging and querying the test procedures and reference sources as the basis for evidence. Implications are discussed for science teaching and learning and further study on argument-based inquiry in online environments.  相似文献

Doug Kirby transformed the field of sex education by conducting rigorous research that led to new, critical insights about ways to strengthen programmes, evaluation and policies related to sexual health throughout the world. Throughout his career, Kirby was meticulous in compiling evidence and translating findings into actionable recommendations for interventions, research and policy. He published more than 150 scientific articles, book chapters and monographs that have been widely cited and more than 900,000 copies of his publications have been distributed. Kirby's impact has been recognised with awards from numerous professional organisations and his unique and powerful scientific voice is greatly missed by his colleagues and friends.  相似文献

The purpose of this article was to highlight important research needs related to physical activity in 3- to 5-year-old children. We identified research needs in 3 major categories: health effects, patterns of physical activity, and interventions and policies. The top research needs include identifying the health effects of physical activity, the effects of physical activity on the development of healthy weight, the effects of physical activity on learning and behavior, and the health implications of sedentary behavior. Research questions concerning patterns of physical activity include determining the prevalence of 3- to 5-year-olds meeting the current physical activity guidelines; the social and environmental factors that influence physical activity in home, preschool, and community settings; and how physical activity tracks into later childhood, adolescence, and adulthood. Research questions about interventions and policies include identifying the most effective strategies to promote physical activity in home, child care, and community settings and to reach diverse populations of young children, identifying effective intervention implementation and dissemination strategies, and determining the effectiveness of national, state, local, and institutional policies for increasing physical activity. In conclusion, research is needed to establish a full understanding of the health implications of physical activity in 3- to 5-year-old children, to better understand the nature of physical activity behavior in this group, and to learn how to promote physical activity in young children.  相似文献

Centralized Online Resources Acquisitions and Licensing (CORAL) is an open source electronic resources management system originally developed by the University of Notre Dame Hesburgh Libraries. The CORAL system consists of five modules designed to manage the library electronic resources life-cycle, including licensing and contact information, procurement and activation workflow, usage statistics, and the storage of documentation. CORAL was designed as a flexible and customizable management system, with the ability to utilize each module independently or as a suite to maintain the electronic resources management needs of individual institutions. Scott Vieira of Rice University, Steve Oberg of Wheaton College, and Andrea Imre of Southern Illinois University Carbondale present on the functionality of CORAL and demonstrate the system’s flexibility and extensibility in managing library electronic resources.  相似文献

Prospective longitudinal data collection is an important way for researchers and evaluators to assess change. In school-based settings, for low-risk and/or likely-beneficial interventions or surveys, data quality and ethical standards are both arguably stronger when using a waiver of parental consent—but doing so often requires the use of anonymous data collection methods. The standard solution to this problem has been the use of a self-generated identification code. However, such codes often incorporate personalized elements (e.g., birth month, middle initial) that, even when meeting the technical standard for anonymity, may raise concerns among both youth participants and their parents, potentially altering willingness to participate, response quality, or generating outrage. There may be value, therefore, in developing a self-generated identification code and matching approach that not only is technically anonymous but also appears anonymous to a research-naive individual. This article provides a proof of concept for a novel matching approach for school-based longitudinal data collection that potentially accomplishes this goal.  相似文献

In an attempt to better prepare future teachers to fight against social injustice, support their culturally and linguistically diverse students and wrestle with social and educational complexities around the globe, many education programs have increased the number of study abroad programs and international service learning projects. In this qualitative study, we explored seven preservice teachers’ experiences related to humanizing pedagogy after participating in a study abroad program combined with an international service-learning project in a South African rural community. Analyzing multiple data sources such as interviews and reflective journals, we discovered that the preservice teachers grappled with the political, social, economic, and educational differences they encountered during the international project and wrestled with conflicting ideas and beliefs about poverty and language. They identified their relationships with students as catalysts to address these educational issues and their need to reverse systemic inequities. They built caring relationships with students in the community and developed additive perspectives the focused on the students’ community cultural capital. The preservice teachers expressed deep critical reflection and a desire to promote a more fully human educational world where students have the opportunities to enact their agency, their creativity, and their language and culture.  相似文献

This study investigates the links between race, school choice and educational stratification in South Africa. It focuses on racial differences in families’ efforts to take advantage of choice by transferring to opportunity (i.e., transferring to a school perceived to offer students better access to educational opportunity than their current school) and explores the implications of those transfers for emerging patterns of racial stratification in access to high quality schools. Findings reveal significant racial variation in transfers to opportunity and suggest a complex link between race and the ways in which historically disadvantaged groups have engaged with the post-apartheid educational opportunity structure.  相似文献

Many professional development information sources are available to catalogers, who may be constrained by limited time and money to devote to them. This article reports the results of a survey gathering information on six types of information sources: journal articles, conferences, electronic discussion lists, blogs, microblogs, and social networking sites. Catalogers rated these resources regarding their importance to filling professional development needs, the reliability of the information disseminated, and their usefulness for obtaining specific types of information. The results should help catalogers and their administrators decide where to focus their attention both as consumers and disseminators of continuing education information.  相似文献
