Little research has focused on tobacco use among deaf and hard of hearing youth. Findings are reported from a first-ever tobacco-related survey, completed by 226 California middle and high school students using either a written questionnaire or the Interactive Video Questionnaire, an interactive multimedia computer video technology. Rates for current smoking (3.1%), ever smoking (45.1%), and multiple types of tobacco use (10.6%) were found to be lower than among high school students generally; mainstreamed students were likelier to have ever tried smoking than their deaf school peers (57.8% vs. 31.8%). No statistically significant associations were found between ever smoking and race/ethnicity, gender, school performance, or prelingual vs. postlingual deafening; a quarter of the sample experienced occasional peer pressure to use tobacco products. Tobacco use covariates, exposure to cigarette marketing and antismoking programming, and tobacco education needs of deaf and hard of hearing youth are discussed.  相似文献

Genetics is the cornerstone of modern biology and understanding genetics is a critical aspect of scientific literacy. Research has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed decisions or to participate in public debates over emerging technologies in molecular genetics. Currently, much of genetics instruction occurs at the high school level. However, recent policy reports suggest that we may need to begin introducing aspects of core concepts in earlier grades and to successively develop students’ understandings of these concepts in subsequent grades. Given the paucity of research about genetics learning at the middle school level, we know very little about what students in earlier grades are capable of reasoning about in this domain. In this paper, we discuss a research study aimed at fostering deeper understandings of molecular genetics at the middle school level. As part of the research we designed a two-week model-based inquiry unit implemented in two 7th grade classrooms (N = 135). We describe our instructional design and report results based on analysis of pre/post assessments and written artifacts of the unit. Our findings suggest that middle school students can develop: (a) a view of genes as productive instructions for proteins, (b) an understanding of the role of proteins in mediating genetic effects, and (c) can use this knowledge to reason about a novel genetic phenomena. However, there were significant differences in the learning gains in both classrooms and we provide speculative explanations of what may have caused these differences.  相似文献

This article describes an empirical study of the ways in which one group of adaptors transformed the plays of William Shakespeare into the medium of the comic book for use in school classrooms. It explores the choices, dilemmas, processes and responsibilities they experienced in doing so. These adaptors had to tackle the burden of ‘Shakespeare’ – what he has come to mean in world literature, the popular imagination, and education – as well as attempting to make the text both appealing and understandable to their intended readers – teenagers studying the plays in school. It is argued that they viewed this task as a pedagogic one and saw the notion of ‘trust’ as central to it. The article therefore has a second aim, which is to use these empirical findings to explore the concept of ‘trust’ and, in particular to outline its relevance for educational research. Using the work of the philosopher Katharine Hawley and the literary theorist Umberto Eco, it is shown that the relational concept of trust is a helpful way of articulating the process of adapting Shakespeare’s work. In the conclusion the ways in which the concept might illuminate broader educational issues related to knowledge, assessment and learning are highlighted.  相似文献

The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation, produced 15 inquiry-based instructional science units for teaching in grades 3–8. Each unit uses computers and probeware to support students’ investigations of real-world phenomena using probes (e.g., for temperature or pressure) or, in one case, virtual environments based on mathematical models. TEEMSS units were used in more than 100 classrooms by over 60 teachers and thousands of students. This paper reports on cases in which groups of teachers taught science topics without TEEMSS materials in school year 2004–2005 and then the same teachers taught those topics using TEEMSS materials in 2005–2006. There are eight TEEMSS units for which such comparison data are available. Students showed significant learning gains for all eight. In four cases (sound and electricity, both for grades 3–4; temperature, grades 5–6; and motion, grades 7–8) there were significant differences in science learning favoring the students who used the TEEMSS materials. The effect sizes are 0.58, 0.94, 1.54, and 0.49, respectively. For the other four units there were no significant differences in science learning between TEEMSS and non-TEEMSS students. We discuss the implications of these results for science education.  相似文献

Objectives:Academic health sciences librarians sought to evaluate the efficacy and future of the Health Information Specialists Program, a five-year consumer health information outreach collaboration with public libraries across the state.Methods:Five focus groups were held with participants from all five years of the program. Thirty-four participants from the program attended. Facilitators used structured interview guides consisting of eleven questions regarding the impact of the collaboration on participants'' abilities to connect themselves or others to health information; the usefulness of materials or knowledge gained and its applications; any consumer health outreach projects that arose from the program; and suggestions for future topics, formats, or modifications. Data was hand-coded and analyzed using the framework analysis methodology for qualitative research.Results:Participants reported feeling improved confidence and comfort in providing health information services to their patrons. Numerous instances of knowledge transfer—in their personal lives, with their colleagues, and for their patrons—were described. Participants reported improved abilities to both find and evaluate consumer health information, and many adapted class materials for their own programming or teaching. Suggestions were provided for future class topics as well as a program website.Conclusion:Based on data from the five focus groups, the Health Information Specialists Program has positively impacted participants in a number of ways. Primary among these were self-reported improvement in both health information retrieval skills and the ability to evaluate the reliability of health information online, as well as in the confidence to help patrons with their health information needs.  相似文献

We examined an alternative model to social skills and social competence training through conceptualizing social skills deficits according to a dichotomous model of either (a) not possessing the necessary skill in the behavioral repertoire or (b) possessing the skill but not using it appropriately. We hypothesized that many skills deficits could be explained by the latter interpretation. Using an ABAC design we compared the use of two behavioral monitoring systems: self‐monitoring and group monitoring of social skills while playing board games. The data suggest substantial increases in prosocial behaviors along with concomitant reductions in antisocial behaviors as a result of the two monitoring procedures. Data also show generalization across gaming situations and maintenance over time. Suggestions are presented for further research to isolate the role of self‐regulation in social skills research. © 2000 John Wiley & Sons, Inc.  相似文献

Objective: To make electronic resources available to library users while effectively harnessing intellectual capital within the library, ultimately fostering the library’s use of technology to interact asynchronously with its patrons (users). Methods: The methods used in the project included: (1) developing a new library website to facilitate the creation, management, accessibility, maintenance and dissemination of library resources; and (2) establishing ownership by those who participated in the project, while creating effective work allocation strategies through the implementation of a content management system that allowed the library to manage cost, complexity and interoperability. Results: Preliminary results indicate that contributors to the system benefit from an increased understanding of the library’s resources and add content valuable to library patrons. These strategies have helped promote the manageable creation and maintenance of electronic content in accomplishing the library’s goal of interacting with its patrons. Conclusions: Establishment of a contributive system for adding to the library’s electronic resources and electronic content has been successful. Further work will look at improving asynchronous interaction, particularly highlighting accessibility of electronic content and resources.  相似文献

In February 2012, the Smithsonian's National Museum of Natural History (NMNH) convened 100 colleagues from 43 organizations to initiate a collaborative learning research agenda focused on examining important areas for innovation to better serve twenty‐first‐century audiences. The conference organizers anticipated that scientists, educators, exhibit professionals, and other members of the natural history community would identify and prioritize research questions about what, how, why, when, and where people learn about natural history. We prepared to engage in a conversation about how natural history museums could change what they do. The participants' overwhelming passion for their work, and for natural history museums and their transformative potential for society, quickly turned the conversation toward how natural history museums should change what they are. The result was an emergent learning research agenda situated within a broader vision for natural history museums.  相似文献

Like the crisis responses to hurricanes, after a tornadic event public libraries play emergency roles both in the short and long term. Community members rely on public libraries for Internet access to request aid, to help find missing family and friends, to file Federal Emergency Management Agency (FEMA) and insurance claims, and, in general, to begin rebuilding their lives. This article reports the quality of services and activities public libraries performed in response and recovery in twelve different communities impacted by tornadoes. The discussion includes an evaluation of the quality of the responses and some recommendations to improve preparedness and response.  相似文献
