This research draws upon merged national databases containing federal crime statistics, community demographic data, and campus characteristics. The study displays the trends in campus crime since 1974, and using 1990 data, examines the relationships between three measures of campus crime and 23 predictors developed for this study. The results show that campus rates of both violent crime and property crime are falling, especially since 1985. Moreover, students are considerably safer on campus than in the cities and communities surrounding them. The lowest average crime rates are found at two-year colleges, while the highest overall rates are at medical schools and health science centers. None of the community characteristics, including community crime and poverty rates, are significantly associated with campus crime. While campus organizational measures in general are more highly related to campus crime than are student characteristics, we find differences in the patterns of variables associated with violent crime versus property crime. Factors associated with property crime are partially consistent with existing theory on criminal activity. Factors associated with violent crime are more complex and difficult to predict.An earlier version of this paper was the winner of the regional Best Paper Award from the North East AIR annual meeting in Bolton Landing, N.Y., November 1993. It was presented again at the Association for Institutional Research Forum, New Orleans, Louisiana, May 1994. 相似文献

Designing informal learning experiences for early career academics using a knowledge ecosystem model
Faye Miller Helen Partridge Christine Bruce Brian Hemmings 《Journal of Further & Higher Education》2017,41(5):692-705
This article presents a ‘knowledge ecosystem’ model of how early career academics experience using information to learn while building their social networks for developmental purposes. Developed using grounded theory methodology, the model offers a way of conceptualising how to empower early career academics through (1) agency (individual and relational) and (2) facilitation of personalised informal learning (design of physical and virtual systems and environments) in spaces where developmental relationships are formed, including programmes, courses, events, community, home and social media. It is suggested that the knowledge ecosystem model is suitable for use in designing informal learning experiences for early career academics. 相似文献

The collective consciousness of effective groups of researchers is characterized by shared understandings of their research object or territory. In this study, we adopted a phenomenographic approach to investigate information technology (IT) research, and its objects and territories, as they are constituted in the experience of IT researchers. Semi‐structured interviews were conducted with researchers representing different sub‐disciplines. Analysis revealed the variation in meaning associated with the idea of IT research; and the awareness structures through which participants experience variation in ways of seeing the object and territories of IT research. Eight ways of seeing IT research were found. The outcomes of our project appear to make visible the changes and developments that are an essential part of the character and experience of contemporary IT research. 相似文献

A cowse‐integrated programme of library instruction has been developed for the School of Civil Engineering at the Queensland University of Technology, Australia; library instruction being one of the means selected to improve the research efforts of fourth year project students. The programme has been developed through consultation between the Civil Engineering Research Project Coordinator and the Civil Engineering Reference Librarian. Its aims are derived from those established for the fourth year research projects. Attention is focussed on the nature of the programme and the impact of instruction on fourth year research project students. Students who had received extended library instruction were compared with students from the previous year. Evidence suggests that the instruction has improved the information seeking behaviour of the students and their literature reviews. 相似文献

For early childhood, the domain of geometry and spatial reasoning is an important area of mathematics learning. Unfortunately,
geometry and spatial thinking are often ignored or minimized in early education. We build a case for the importance of geometry
and spatial thinking, review research on professional development for these teachers, and describe a series of research and
development projects based on this body of knowledge. We conclude that research-based models hold the potential to make a
significant difference in the learning of young children by catalyzing substantive change in the knowledge and beliefs of
their teachers. 相似文献

This paper presents the concept of critical flexibility as an alternative to eclecticism in instructional design. Eclecticism is often viewed as a persuasive alternative to theoretical
orthodoxy (i.e., rigid use of a single perspective or process) due to the openness and flexibility it purports to offer. In
contrast, the authors argue that eclecticism ignores or discourages critical reflection regarding background understanding
(e.g., implicit assumptions and values) and perpetuates the lack of openness and flexibility commonly associated with orthodoxy.
Critical flexibility, as an alternative to eclecticism, emphasizes an awareness of background understanding, but construes
it as capable of being explicated, critically examined, adjusted in specific contexts, and refined or developed over time
to facilitate increasingly flexible and effective design practices. The authors clarify the nature of critical flexibility
as a general way of being involved in the design process, suggest how it helps overcome the traditional theory–practice split,
and discuss several of its implications for scholarship and training. 相似文献

If children are engaged in science lessons, their learning is likely to be better and, in the long term, careers in science
and technology will remain open. Given that attitudes can develop early and be difficult to change, it is important for teachers
of younger children to know how to foster engagement in science. This study identified what a cohort of 79 pre-service teachers
in England considered to be engaging elementary science lessons and compared their notions with teacher behaviours known to
be conducive to engagement. First, all brought beliefs about how to engage children in science lessons to their training.
They tended to favour children’s hands-on activity as an effective means of fostering attentive participation in learning,
although many had additional ideas. Nevertheless, the means and ends of their ‘pedagogies of engagement’ tended to be simple
and narrow. Trainers need to ensure that notions of engagement are wide enough to cope with a variety of teaching situations,
as when hands-on experience is not feasible, effective or appropriate. At the same time, teachers will need to recognise that
one approach may not suit all learners. Without this, there is the risk that they will lack the skills to engage children
in science. Nevertheless, these beliefs could offer a useful starting point for trainers who wish to widen pre-service teachers’
conceptions of engagement and increase their repertoire of teaching behaviours. 相似文献
