Present analysis focuses on the way girls and boys perceive their gender identity in mixed or single-sex schools. Use was made of data concerning 6427 third-year pupils from 25 coeducational and 43 single-sex (21 girls and 22 boys schools) academically oriented secondary schools in Belgium. A multilevel analysis (Hierarchical Linear Modeling) was performed controlling for parental socioeconomic status (SES), academic performance, curriculum enrolment, parental support and school mean SES. It was mainly found that coeducational school girls not only tend to identify themselves more strongly in terms of feminine traits than single-sex school girls, but also in terms of masculine traits, even though their classroom behaviour appears to be much more inhibited.  相似文献

In this article, an alternative for Tinto’s integration theory of student persistence is proposed and tested. In the proposed theory, time available for individual study is considered a major determinant of both study duration and graduation rate of students in a particular curriculum. In this view, other activities in the curriculum, in particular lectures, constrain self-study time and therefore must have a negative impact on persistence. To test this theory, we collected study duration and graduation rate information of all—almost 14,000 students—enrolling in eight Dutch medical schools between 1989 and 1998. In addition, information was gathered regarding the timetables of each of these curricula in the particular period: lectures hours, hours spent in small-group tutorials, practicals, and time available for self-study. Structural equation modeling was used to study relations among these variables. In line with our predictions, time available for self-study was the only determinant of graduation rate and study duration. Lectures were negatively related to self-study time, negatively related to graduation rate, and positively related to study duration. The results suggest that extensive lecturing may be detrimental in higher education. However, in the curricula employing limited lecturing considerable energy was spent in supporting self-study activities of students and preventing postponement of learning. Given our findings, both activities will likely have large pay offs, in particular in curricula with low graduation rates.  相似文献

The study reported here investigated experienced teachers’ views on several nature of science (NOS) issues 2 to 5 years after they completed a demanding secondary science teacher education program in which the NOS was an extensive and recurring component. Both quantitative and qualitative data were collected and analyzed to determine study participants’ NOS understanding. Study participant’s NOS views were determined to be generally accurate and robust, suggesting that experiences in their science teacher education program had a long-lasting positive impact on NOS understanding. The preservice program that study participants completed has several unique features that may account for that long-lasting impact and has implications for preservice and inservice science teacher education professional development.

This article presents an up‐to‐date portrayal of the greatly changed landscape of scholarly journal publishing and identifies the emerging trends characterizing it. We consider the attributes, novelty, and disruptive potential of different models, which range from improvements to the extant model to attempts at reconfiguration and transformation. We propose that journal transition can be seen as falling into three categories. The first is enhanced models of the traditional scholarly journal, which typically afford enriched functionality that breaks the bonds of the printed page whilst otherwise remaining wholly traditional in their offerings. The second category is innovative models of the traditional scholarly journal, which aim at supporting the journal in performing its traditional roles through convention‐altering ways. The third category is the possible alternatives to the traditional journal, which represent a move towards alternative modes of knowledge dissemination. This review shows that each of the models identified makes contributions to enriching the reporting and showcasing of scholarly output. They also make it more effective and more efficient. However, we conclude that none of the possible alternatives being discussed can serve as a full‐fledged alternative to the journal.  相似文献

After two-years of repeat interviewing early career sciences/social sciences researchers from around the world about their work life and scholarly communications in pandemic-times, the Harbingers-2 project is in a position to release quantitative data on the pandemic's overall impact. The data comes from around 50 questions asked in the third and final round of interviews with 147 early career researchers (ECRs), which had a codifiable element to them (such as yes, no, do not know). The 19 scholarly topics covered include: pandemic-related research; research funding; changes to the workplace/working from home; pandemic-incurred stress and anxiety; teaching; employment security; career progression; mentoring; assessment (including metrics); collaboration; searching/finding information; ethics; networking; informal communication; publishing; sharing; pre-prints; outreach; and scholarly transformations. The main findings are that in six broad aspects of ECRs' work-life and scholarly behaviour, more than 50% of ECRs were impacted by the pandemic, with remote teaching having the greatest impact. By way of comparison, in another six aspects there was little change, least of all when it came to sharing activities. Among the countries studied, Malaysia stood out as being the most impacted, and of the disciplines it was the medical sciences and the soft social sciences most impacted.  相似文献

Signed languages continue to be a key element of deaf education programs that incorporate a bilingual approach to teaching and learning. In order to monitor the success of bilingual deaf education programs, and in particular to monitor the progress of children acquiring signed language, it is essential to develop an assessment tool of signed language skills. Although researchers have developed some checklists and experimental tests related to American Sign Language (ASL) assessment, at this time a standardized measure of ASL does not exist. There have been tests developed in other signed languages, for example, British Sign Language, that can serve as models in this area. The purpose of this study was to adapt the Assessing British Sign Language Development: Receptive Skills Test for use in ASL in order to begin the process of developing a standardized measure of ASL skills. The results suggest that collaboration between researchers in different signed languages can provide a valuable contribution toward filling the gap in the area of signed language assessment.  相似文献

The Harbinger project was a 3‐year‐long international study of the changing attitudes and behaviours of early career researchers (ECRs). One of the aims of the project was to discover if ECRs were adopting disrupting platforms that, legitimately or illegitimately, promote openness and sharing. It has been alleged that such an adoption appeals to them as Millennials. More than 100 ECRs from seven countries were questioned annually, and questions about Sc‐Hub were raised as part of discussions about discovery and access. Interview data were supplemented by desk research and Google Trends statistics. It was found that Sci‐Hub use was increasing and that a quarter of the ECRs now use it, with French ECRs being the biggest users. However, Sci‐Hub is making little headway with ECRs from the UK, USA, Malaysia, and China, although in China's case, this can be explained by it being banned and the country having its own equivalent, www.91lib.com . Sci‐Hub is used as much for convenience as necessity; use is not connected to the strength of library provision and and it has been suggested that it represents a bigger threat to publishers than ResearchGate, whose star might be waning.  相似文献
