The purpose of this study was to propose a design for a Superintendent of Documents (SuDocs) number search key to retrieve bibliographic records for United States Government documents from OCLC's On-Line Union Catalog. Experimentation with a test file of 25,000 records indicated that a search key derived from a maximum of the first 14 digits in the SuDocs number is sufficiently distinctive to obtain an expected average retrieval of 2.5 records per search. OCLC will implement a SuDocs number search key in the future. It is expected that this key will be a valuable tool for library catalogers and users. 相似文献

Allowing learners to choose: self-controlled practice schedules for learning multiple movement patterns 总被引:1,自引:0,他引:1
For this study, we investigated the effects of self-controlled practice on learning multiple motor skills. Thirty participants were randomly assigned to self-control or yoked conditions. Participants learned a three-keystroke pattern with three different relative time structures. Those in the self-control group chose one of three relative time structures before each of 90 practice trials; yoked participants were not allowed to choose but were yoked to a self-control participant and followed that individual's sequence of practice trials. Results of the 24-hr serial transfer test revealed the self-control group exhibited significantly lower relative timing error, absolute error, and total error than the yoked group. Findings further support the efficacy of self-controlled learning 相似文献

In this paper we explore the relationship between learning gains, measured through pre‐assessment and post‐assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future’s BioBLAST!® (BB) software program in a high school biology classroom. We found that the argumentative structures, the quality of these structures, and the identities that students take on during collaborative group work are critical in influencing student learning and achievement in science. We provide recommendations for instructors implementing argumentation in their science classrooms, and provide suggestions for the development of future research in this area. 相似文献

The motivational styles of 25 children with attention-deficit/hyperactivity disorder, combined type (ADHD/C), 13 children with ADHD, inattentive type (ADHD/IA), and 25 nondiagnosed controls (NC) were compared using parent, teacher, and self-ratings. Both ADHD subtypes demonstrated motivational impairment characterized by a preference for easy work, less enjoyment of learning, less persistence, and a greater reliance on external than on internal standards to judge their performance relative to NC. Some motivational style differences between ADHD subtypes were also revealed, with the ADHD/C group more motivated by competitiveness and a desire to be perceived as superior to others and the ADHD/IA group less uncooperative and possibly more passive in their learning styles. When IQ was statistically controlled, these results were generally unchanged. The contributing role of motivational deficits to the generally poor academic functioning of children with ADHD is discussed, along with potential intervention implications of the divergent motivational styles of different ADHD subtypes. 相似文献

This study examined the time course of typing in prelingually and profoundly deaf as well as hearing individuals. Both groups
of participants performed a written picture naming task and a written pseudoword task. Keystroke timing measurements from
the written picture naming task revealed that the deaf as well as the hearing group were significantly delayed at syllable
boundaries compared to identical within-syllable letter combinations. As the deaf are impoverished with respect to phonology
based on spoken language experience, we postulate that syllabic segmentation is not crucially dependent on experience with
spoken language. Furthermore, delays at syllable boundaries were not affected by word frequency in both groups, in contrast
to the keys straddling a root morpheme boundary. Together with the finding that delays at syllable boundaries also occur in
pseudowords, the experiments provide strong evidence towards post-lexical syllabification processes. Our results support previous
findings which claim that (1) orthosyllables are autonomous and mode-specific entities, and (2) that the principles of syllabic
organisation apply post-lexically. 相似文献

The paper reports on key findings of a research project that examined the roles that community-based sporting clubs in the Australian state of Victoria play in shaping young people's understandings and uses of alcohol. Our research imagined clubs as community hubs that are located in complex networks that impact on the ways that clubs understand their locations in communities, and which have unpredictable influences and consequences on club histories, culture and orientations to issues such as young people and alcohol use. The paper focuses on understanding the key roles played by club leaders in facilitating change and transformation in these contexts, particularly in terms of alcohol-related practices and the potential impact of these on young people's uses and understanding of alcohol. We situate these findings in a framework that draws on the literature of complexity science and complex adaptive systems (CAS) to suggest that these practices and changes need to be understood in ways that allow for complexity, uncertainty, emergent behaviours and adaptive change. 相似文献
