This paper is the first of two Learned Publishing articles in which we report the results of a series of interviews with senior publishers and editors exploring open access megajournals (OAMJs). Megajournals (of which PLoS One is the best known example) represent a relatively new approach to scholarly communication and can be characterized as large, broad‐scope, open access journals that take an innovative approach to peer review, basing acceptance decisions solely on the technical or scientific soundness of the article. This model is often said to support the broader goals of the open science movement. Based on in‐depth interviews with 31 publishers and editors representing 16 different organizations (10 of which publish a megajournal), this paper reports how the term ‘megajournal’ is understood and publishers’ rationale and motivations for launching (or not launching) an OAMJ. We find that while there is general agreement on the common characteristics of megajournals, there is not yet a consensus on their relative importance. We also find seven motivating factors that were said to drive the launch of an OAMJ and link each of these factors to potential societal and business benefits. These results suggest that the often polarized debate surrounding OAMJs is a consequence of the extent to which observers perceive publishers to be motivated by these societal or business benefits.  相似文献

The problem of the underrepresentation of girls in science in Australian schools is often attributed to their poor performance. Yet the role of both the home and the school in affecting female science achievement is rarely examined empirically. The comprehensiveness of the Second International Science Study database provided an excellent opportunity to investigate the presence of gender differences in science achievement. Although previous studies of gender differences in science achievement have relied on methodology that has not adequately accounted for the school effects, this study used the design effect and hierarchical linear modeling (multilevel analysis) to explore whether there were significant gender differences. The relative contribution of schools to student achievement was examined, and school-level differences were found to contribute significantly toward explaining variations in student performance. Although statistically significant sex differences were found in physics achievement for 10-year-old, 14-year-old, and year-12 students, school effects were much more powerful in explaining student differences (9–19%) when compared with gender (3%).  相似文献

This study examined the associations between classmates’ reading-related gender stereotypes and students’ reading self-efficacy, self-concept, motivation, and achievement. Our sample consisted of 1,508 fifth-grade students (49% girls; age: 10.89 years); data were collected at two time points. Multilevel analyses yielded two main results: First, there was a relation between students’ individual reading-related gender stereotypes and their reading self-concept, self-efficacy, and motivation with boys experiencing negative and girls experiencing positive effects. Second, a contextual effect was found: after controlling for students’ individual reading-related gender stereotypes, classmates’ gender stereotypes were negatively related to all of the boys’ reading outcomes. The results provide evidence for the assumption that classmates are important communicators of gender stereotypes and that they reinforce conforming behaviors.  相似文献

This paper describes the use of an activity theory (AT) framework to analyze the ways that distance part time learners and mobile workers adapted and appropriated mobile devices for their activities and in turn how their use of these new tools changed the ways that they carried out their learning or their work. It is argued that there are two key strengths in using an activity theory framework in this context. The first strength is the emphasis activity theory places on tools, including computer artefacts, as mediators of activity. This emphasis focuses attention on the activity itself rather than, for example, simply the interaction between the human and the computer. The focus is on the learner or user’s objectives and activities and the computer is the tool through which the user achieves her objectives. The second strength was referred to briefly above. The AT perspective also enabled analysis of an interactive dynamic process of users or learners and their tools—in this case personal digital assistants (PDAs). It revealed a two way process in which the user adapts the tools they use according to their everyday practice and preferences in order to carry out their activities; and how, in turn, the tools themselves also modify the activities that the user is engaged in. Three case studies illustrate these processes. The first case study is of distance learners’ use of e‐books on PDAs, to supplement their access to other static media such as books and computers. The second case study investigated how mobile workers in the energy industry used mobile devices to access information when away from the office. The third and final case study investigated the use of mobile devices in an art gallery. The paper concludes with a discussion of the information access needs that are apparent in each of these learning contexts, and highlights the pertinent issues in the use of mobile technologies to support lifelong learners’ information needs.  相似文献

This paper describes part of a one–day course run by the authors for Newly Qualified Teachers of art and design (NQTs) planned to develop subject knowledge and assessment expertise. The former was achieved partly through an examination of the roles of drawing in secondary school art and design education. Through review and discussion of their pupils’ drawings, the NQTs developed ideas about the functions and purposes of drawing. These ideas were then refined and some practical work undertaken. The nature of drawing policies for secondary art and design departments was considered. The session concluded with a consideration of ideas that might inform the development of such a drawing policy. Secondly, the authors take up and develop several issues from the NQTs’ ideas and responses. These include reference to participants’ drawing performance and understanding, their judgements about the value of drawing, and to how these may be influenced by factors in art education, including those associated with GCSE and assessment. Finally, reference is made to two distinctive perceptions of drawing in schools and, with reference to the work of Wilson, Hurwitz and Wilson, the authors suggest a strategy and argue for the development of drawing policy and curricula for secondary school art departments. The paper is based on part of a presentation given at the Annual Conference of the NSEAD, York, 2002.  相似文献
