This work explores the use of Clemson University's institutional repository and library catalog in promoting and providing access to the patents granted to its inventors. More specifically, the authors outline the project from generating metadata for patents and crosswalking it into a form that can be batch-uploaded to a bepress Digital Commons repository. They then explore the process of harvesting the records from the repository and using MarcEdit to crosswalk it into the library catalog. The process could easily be adapted to other nontraditional forms of scholarship.  相似文献

ABSTRACT

Previous research has mostly focused on the demographic and academic correlates of library anxiety. This study focused on the “library anxiety” and “emotion perception” of students, with the objective of examining the relationship between these two concepts. In total, 279 self-reporting questionnaires were used for analysis. The results confirmed the existence of the phenomenon of library anxiety, with these students being more anxious regarding the “user education” and “user knowledge” factors. They showed greater skills of emotion perception. A negatively significant relationship appeared between library anxiety and emotion perception. The results suggest that user education and emotion perception training programs should be developed to overcome students' problems.  相似文献

SHORT REPORTS     
This short report explores the quality of the care process for children with intellectual disabilities. A Delphi procedure was used to identify a set of indicators for the quality of the care process reflecting the perspectives of the care providers, the parents and the experts. The sample consisted of 59 individuals involved in different ways in the process of the caring for children with intellectual ­disabilities. The first round of the Delphi procedure resulted in 56 themes, distributed across four different phases of the care process. In the second round of the Delphi procedure, these themes were elaborated into 346 indicators that were, in turn, evaluated on their importance for the quality of the care process by the respondents. Finally, 328 indicators did meet the 85% criterion for consensus. Six themes proved to be relevant in all phases of care: transfer of information, report, consultation, attitude of care provider, respect and appointments. The operationalization of quality of care presented in this study points in the direction of actually measuring, monitoring and improving the quality of care for children with intellectual disabilities.  相似文献

Although molecular-level details are part of the upper-secondary biology curriculum in most countries, many studies report that students fail to connect molecular knowledge to phenomena at the level of cells, organs and organisms. Recent studies suggest that students lack a framework to reason about complex systems to make this connection. In this paper, we present a framework that could help students to reason back and forth between cells and molecules. It represents both the general type of explanation in molecular biology and the research strategies scientists use to find these explanations. We base this framework on recent work in the philosophy of science that characterizes explanations in molecular biology as mechanistic explanations. Mechanistic explanations describe a phenomenon in terms of the entities involved, the activities displayed and the way these entities and activities are organized. We conclude that to describe cellular phenomena scientists use entities and activities at multiple levels between cells and molecules. In molecular biological research, scientists use heuristics based on these intermediate levels to construct mechanistic explanations. They subdivide a cellular activity into hypothetical lower-level activities (top-down approaches) and they predict and test the organization of macromolecules into functional modules that play a role in higher-level activities (bottom-up approaches). We suggest including molecular mechanistic reasoning in biology education and we identify criteria for designing such education. Education using molecular mechanistic reasoning can build on common intuitive reasoning about mechanisms. The heuristics that scientists use can help students to apply this intuitive notion to the levels in between molecules and cells.  相似文献

In science education in the Netherlands new, context‐based, curricula are being developed. As in any innovation, the outcome will largely depend on the teachers who design and implement lessons. Central to the study presented here is the idea that teachers, when designing lessons, use rules‐of‐thumb: notions of what a lesson should look like if certain classroom outcomes are to be reached. Our study aimed at (1) identifying the rules‐of‐thumb biology teachers use when designing context‐based lessons for their own classroom practice, and (2) assessing how these personal rules‐of‐thumb relate to formal innovative goals and lesson characteristics. Six biology teachers with varying backgrounds designed and implemented a lesson or series of lessons for their own practice, while thinking aloud. We interviewed the teachers and observed their lessons. Our results suggest that rules‐of‐thumb, which differed substantially among the teachers, indeed to a great extent guide the decisions teachers make when designing (innovative) lessons. These rules‐of‐thumb were often strongly associated with intended lesson outcomes. Also, teachers’ personal rules‐of‐thumb were more powerful in determining the lesson design than formal innovative goals and lesson characteristics. The results of this study encourage more research into how rules‐of‐thumb reflect teachers’ practical knowledge, for which suggestions are made.  相似文献

Contemporary genomics research will impact the daily practice of biology teachers who want to teach up-to-date genetics in secondary education. This article reports on a research project aimed at enhancing biology teachers’ expertise for teaching genetics situated in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of an educational approach based on situated learning. What expertise do biology teachers need for teaching genetics in the personal health context of genetic testing? This article describes the required expertise by exploring the educational practice. Nine experienced teachers were interviewed about the pedagogical content, moral and interpersonal expertise areas concerning how to teach genetics in the personal health context of genetic testing, and the lessons of five of them were observed. The findings showed that the required teacher expertise encompasses specific pedagogical content expertise, interpersonal expertise and a preference for teacher roles and teaching approaches for the moral aspects of teaching in this context. A need for further development of teaching and learning activities for (reflection on) moral reasoning came to the fore. Suggestions regarding how to apply this expertise into context-based genetics education are discussed.  相似文献

Recent developments in the field of genomics will impact the daily practice of biology teachers who teach genetics in secondary education. This study reports on the first results of a research project aimed at enhancing biology teacher knowledge for teaching genetics in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of such a situated learning approach. What content knowledge do biology teachers need for teaching genetics in the personal health context of genetic testing? This study describes the required content knowledge by exploring the educational practice and clinical genetic practices. Nine experienced teachers and 12 respondents representing the clinical genetic practices (clients, medical professionals, and medical ethicists) were interviewed about the biological concepts and ethical, legal, and social aspects (ELSA) of testing they considered relevant to empowering students as future health care clients. The ELSA suggested by the respondents were complemented by suggestions found in the literature on genetic counselling. The findings revealed that the required teacher knowledge consists of multiple layers that are embedded in specific genetic test situations: on the one hand, the knowledge of concepts represented by the curricular framework and some additional concepts (e.g. multifactorial and polygenic disorder) and, on the other hand, more knowledge of ELSA and generic characteristics of genetic test practice (uncertainty, complexity, probability, and morality). Suggestions regarding how to translate these characteristics, concepts, and ELSA into context-based genetics education are discussed.  相似文献

This article presents an exploration of the methodology of action research. It is a reflection on a study where an action research methodology used by the researcher to research and develop theory, became part of the model of professional development. In this way, the action research methodology permeated into the culture of the way people worked together. This article describes how a researcher can not only use action research methods to gather data on a development, but can also lead a group of action researchers towards a greater awareness of their own practice in their own institutions. A greater awareness of the bigger issues in education is also an outcome achieved by facilitating critical discussion on key issues. There can be action research for research purposes, action research for action purposes and action research communities that can lead to emancipatory practices in education. These are concurrent strands within action research communities.  相似文献
