Both classroom instruction and lexical database development stand to benefit from applied research on sign language, which takes into consideration American Sign Language rules, pedagogical issues, and teacher characteristics. In this study of technical science signs, teachers' experience with signing and, especially, knowledge of content, were found to be essential for the identification of signs appropriate for instruction. The results of this study also indicate a need for a systematic approach to examine both sign selection and its impact on learning by deaf students. Recommendations are made for the development of lexical databases and areas of research for optimizing the use of sign language in instruction. 相似文献

Preschool classrooms were investigated to determine the extent to which quality is related to children’s literacy development.
The study included 24 classrooms of 428 prekindergarten children in a large, urban Midwestern school district. Results suggest
that global classroom quality and literacy environment quality are strongly related. Literacy environment quality and children’s
literacy abilities are also related. Differences in classroom quality were found to have an impact on children’s literacy
scores—the higher the quality, the higher the scores. This article also describes lessons learned from the investigation and
provides suggestions for teachers and administrators for improving quality to enhance literacy development. 相似文献

BACKGROUND: Librarians at the University of Alberta have been involved with teaching undergraduate medical and dental education for several years. After 1 year of increased librarian involvement at the problem-based learning (PBL), small-group level, informal feedback from faculty and students suggested that librarians' participation in PBL groups was beneficial. There was, however, no real evidence to support this claim or justify the high demand on librarians' time. OBJECTIVES: The study aimed to determine whether having a librarian present in the small-group, problem-based learning modules for first-year medical and dental students results in an improved understanding of evidence-based medicine concepts, the nature of medical literature, and information access skills. METHODS: One hundred and sixty-four first-year medical and dental students participated in the study. There were a total of 18 PBL groups, each with approximately nine students and one faculty tutor. Six librarians participated and were assigned randomly to the six intervention groups. Students were given pre- and post-tests at the outset and upon completion of the 6-week course. RESULTS: Post-test scores showed that there was a small positive librarian impact, but final exam scores showed no impact. There was also no difference in attitudes or comfort levels between students who had a librarian in their group and those who did not. CONCLUSIONS: Impact was not sufficient to warrant continued participation of librarians in PBL. In future instruction, librarians at the John W. Scott Health Sciences Library will continue to teach at the larger group level. 相似文献

The notion of presence in virtual learning environments: what makes the environment "real" 总被引：1，自引：0，他引：1

To know where they are in the environment, humans rely on their senses for information. If the environment is artificially generated then it raises the question as to what information is needed to allow humans to know their location in the environment and have a more tacit feeling of presence within it. This paper looks at the role of Virtual Environments as conceptual learning tools in Science and the notion of "Presence" within these types of environments. Presence in this context is based on the stream of sensory input, organized by our perceiving systems, and out of which emerges our sense of being in and of the world. This feeling is also engendered by our ability to affect the world through touch, gesture, voice etc. These are very private actions and to research this we conducted interviews with competent computer users about their feelings of "presence" when using virtual environments. One of the main findings has been that audio feedback is perceived to be one of the most important features that engender a sense of presence. We have also found that ease of navigation around the environment affects perceptions of presence and this is reflected to some extent with users' personal experience. 相似文献
