The concept map tool set forth by Novak and colleagues is underutilized in education. A meta-analysis has encouraged teachers to make extensive use of concept mapping, and researchers have advocated computer-based concept mapping applications that exploit hyperlink technology. Through an NSF sponsored geosciences education grant, middle and secondary science teachers participated in professional development to apply computer-based concept mapping in project-based learning (PBL) units that investigated local watersheds. Participants attended a summer institute, engaged in a summer through spring online learning academy, and presented PBL units at a subsequent fall science teachers’ convention. The majority of 17 teachers who attended the summer institute had previously used the concept mapping strategy with students and rated it highly. Of the 12 teachers who continued beyond summer, applications of concept mapping ranged from collaborative planning of PBL projects to building students’ vocabulary to students producing maps related to the PBL driving question. Barriers to the adoption and use of concept mapping included technology access at the schools, lack of time for teachers to advance their technology skills, lack of student motivation to choose to learn, and student difficulty with linking terms. In addition to mitigating the aforementioned barriers, projects targeting teachers’ use of technology tools may enhance adoption by recruiting teachers as partners from schools as well as a small number that already are proficient in the targeted technology and emphasizing the utility of the concept map as a planning tool. 相似文献

Today's world of continuous change thrives on creative individuals. Anecdotal reports suggest that creative performance benefits from unconscious processes. Empirical research on the role of the unconscious in creativity, though, is inconsistent and thus far has focused mainly on one aspect of the creative process - idea generation. This is the first study to assess the role of the unconscious mind for both idea generation and idea selection. Participants generated creative ideas immediately, after conscious thought, or after a period of distraction during which unconscious thought was hypothesized to take place. After having listed their ideas, participants selected their most creative idea. Performance in idea generation was similar between conscious and unconscious thought; however, individuals who had unconsciously thought about ideas were better in selecting their most creative idea. These findings shed more light on the role of unconscious processes in creativity, and provide a means to enhance creative performance. 相似文献

This paper discusses the evaluation of an informal science education project, The Birdhouse Network (TBN) of the Cornell Laboratory of Ornithology. The Elaboration Likelihood Model and the theory of Experiential Education were used as frameworks to analyse the impact of TBN on participants’ attitudes toward science and the environment, on their knowledge of bird biology, and on their understanding of the scientific process. The project had an impact on participants’ knowledge of bird biology. No statistically significant change in participants’ attitudes toward science or the environment, or in participants’ understanding of the scientific process, could be detected. The results suggest that projects must make explicit to participants the issues that they are experiencing. In addition, the results suggest that more sensitive measures need to be designed to assess attitude change among environmentally aware citizens. 相似文献

The current study is an analysis of public service announcements (PSAs) from an effective safer sex campaign that utilized a sensation-seeking targeting (SENTAR) approach. Two random samples of heterosexually active young adults (sample one N = 1,463, sample two N = 895) viewed different sets of safer sex PSAs on a laptop computer and answered questions about their perceived sensation value and perceived effectiveness. Multiple regression analyses examined the impact of (a) demographic, (b) individual difference, (c) sexual context, and (d) message variables including perceived message sensation value (PMSV) on the perceived message effectiveness (PME) of the PSAs. Results indicated that females, African Americans, condom users, and those with less education viewed the PSAs as slightly more effective than males, Caucasians, non-condom users, and those with more education. PMSV and personal utility emerged as the strongest predictors of PME, even after controlling for all of the aforementioned variables. Implications for further research on PMSV and perceived and actual effectiveness of PSAs are offered. 相似文献

A recent study of a magazine distributed by a powerful conservative Christian group determined the organization showed strong concern for “visual culture.” The publication directed its readers on how to understand the seen world. The present study analyzes a periodical of an avowedly secular group to understand how they might manifest similar or different concerns. On the whole, the content of the magazine called The Humanist appears to indicate that visual culture is as important to agnostics as it is to theists. 相似文献

Policies designed to promote the commercialization of university science have provoked concern that basic and publicly accessible research may be neglected. Commercialization policies have altered traditional institutional incentives and constraints, which raises new questions regarding the influence of scientists’ values on university research agendas. Our research builds on previous quantitative studies measuring changes in research outcomes and qualitative studies probing differentiation among scientists’ value orientations. We developed a nation-wide survey of 912 plant and animal biotechnology scientists at 60 research universities. Our analysis reveals that scientists’ value orientations on what we classify as “market” and “expert” science affect the amount of industry funding they receive, the proprietary nature of their discoveries, and the percentage of basic science research conducted in their laboratories. We also find that the percentage of industry funding is significantly associated with more applied research. Our findings provide insights for science and society theory and suggest that strong incentives for public-science research along with adequate public-research funds to preserve the university's vital role in conducting basic and non-proprietary research are needed to complement private-sector research investments at universities. 相似文献

This paper reports on the results of a study in which the discourse within 75 professional development school (PDS)-related publications was examined to determine where the power, influence, and representation lies in PDS partnerships, as indicated by how those partnerships are described in writing. The results found that while university faculty overwhelmingly wrote the articles, their perspectives and experiences were under-represented in the literature and, moreover, their influence within the partnerships appeared to be negligible. School and university administrators were similarly absent in PDS writing. Significantly, university authors and researchers represented themselves in a way that was highly deferential to practitioners and denigrated the role of theory and research in PDS work. In contrast to the traditional image of university dominance of partnerships, this research suggests that the real power and influence in PDS partnerships are the classroom teachers. The paper concludes with suggestions for creating a new, shared PDS discourse that tries to blur the artificial lines between theory and practice. 相似文献
