While some researchers have argued for science classrooms that embrace open-inquiry by engaging students in doing science as scientists do (cf. National Research Council [NRC] 1996; Driver et al. in Sci Educ 84:287–312, 2000; Windschitl et al. in Sci Educ 87(1):112–143, 2008), others have argued that open-inquiry is impractical, ineffective, and perhaps even counter-productive towards promoting normative scientific ideas (cf. Kirschner et al. in Educ Psychol 41(2):75–86, 2006; Settlage in J Sci Teach Educ 18:461–467, 2007). One of the challenges in informing the debate on this issue is the scarcity of well-documented courses that engage students in open-inquiry characteristic of scientific research. This paper describes the design, implementation, and outcomes of such a course for undergraduates planning on becoming elementary teachers. The goal of the class was to immerse future teachers in authentic, open-inquiry (without specific learning goals related to scientific concepts) in hopes that students would come away with a deeper understanding of the nature of science (NOS) and improved attitudes towards science. Data collected from a variety of sources indicate that an authentic, open-inquiry experience is feasible to implement in an undergraduate setting, gives students a more sophisticated NOS understanding, improves students’ attitudes towards science and open-inquiry, and changes the way they intend to teach science in their future classrooms.  相似文献

Romanian libraries have had a rich heritage of collecting and preserving materials in the domains of national and foreign history, literature, art, and science. During the communist regime they served as propaganda tools for the government's Marxist ideology. In post-communist Romania, there is a desire among some librarians to promote change from a system of limited access to information to a more open system that focuses on quality improvement of library services, operations, and organization. In their efforts to overcome the communist legacy to libraries in their country, some Romanian librarians—with local resources and support from international agencies—are implementing western managerial styles and services. This case study reflects the results, assessments, and recommendations from a survey conducted at a workshop of selected Romanian librarians in August 1998. Considerations for the implementation of needed changes are also included.  相似文献

Archival digital image collections are a relatively new phenomenon in college library archives. Digitizing archival image collections may make them accessible to users worldwide. There has been no study to explore whether collections on the Internet lead to users who are beyond the institution or a comparison of users to a national or international audience. This study of the Orang Asli Archive, a repository for anthropological, historical, journalistic, and other documentary sources relevant to Orang Asli peoples and cultures of Malaysia, examines the Web analytics of its digital archival image collections.  相似文献

This longitudinal study, spanning from 1995 through 2012, followed vulnerable youth from upper secondary school (T1) as they made the transition to their early twenties (T2), late twenties (T3) and mid-thirties (T4). We investigated their social network relationships in different phases of adult life, focusing mainly on factors that explain patterns of social adaptation. Internet-mediated relationships were also studied at T4. We found that attending special classes in upper secondary school explained the respondents’ risk of being in a small isolated and bonding network in their early twenties. In the transition from early to late twenties, the relative impact of a changed life situation, which increases the potential of network formation, is a resilience factor. Logistic regression analyses, however, showed that in the transition from T3 to mid-thirties, having intellectual disabilities was a risk factor for social isolation. In particular, males with intellectual disabilities or psychosocial difficulties at this age were isolated in small networks and less likely to be on Facebook/Twitter. A shift of factors in the explanatory model of the transition from school to adult life reflects the relative impact of contextual factors distant and closer in time, shedding light on the principle of social ties to others, linked lives and cumulative disadvantages across the life course.  相似文献

The Comprehensive Evaluation Model is a tool which can be used for the evaluation of nontraditional programs. This Model is useful in helping an educator address issues related to program quality, cost-effectiveness and program improvement. The Model is utilization focused, that is, in applying the Model one assesses who needs evaluative information, and for what purpose. There are four levels of program effects which the evaluator can choose to evaluate. The levels are: 1) participant reaction, 2) participant learning, 3) participant transfer of learning, and 4) organizational impact of the program.  相似文献

Besides viewing knowledge about the nature of science (NOS) as important for its own value with respect to scientific literacy, an adequate understanding of NOS is expected to improve science content learning by fostering the ability to interrelate scientific concepts and, thus, coherently acquire scientific content knowledge. However, there is a lack of systematic investigations, which clarify the relations between NOS and science content learning. In this paper, we present the results of a study, conducted to investigate how NOS understanding relates to students’ acquisition of a proper understanding of the concept of energy. A total of 82 sixth and seventh grade students received an instructional unit on energy, with 41 of them receiving generic NOS instruction beforehand. This NOS instruction, however, did not result in students having higher scores on the NOS instrument. Thus, correlational analyses were performed to investigate how students’ NOS understanding prior to the energy unit related to their learning about science content. Results show that a more adequate understanding of NOS might relate to students’ perspective on the concept of energy and might support them in understanding the nature of energy as a theoretical concept. Students with higher NOS understanding, for example, seemed to be more capable of learning how to relate the different energy forms to each other and to justify why they can be subsumed under the term of energy. Further, we found that NOS understanding may also be related to students’ approach toward energy degradation—a concept that can be difficult for students to master—while it does not seem to have a substantive impact on students’ learning gain regarding energy forms, transformation, or conservation.  相似文献
