AIM AND OBJECTIVES: The aim of this two-part paper is to identify the main transferable lessons learned from both the quantitative and qualitative evaluations of the KA24 (Knowledge Access 24) service of online databases and selected full-text journals for health and social care staff in London and the south-east of England. The objectives of the qualitative evaluation were to assess the enablers and barriers to usage, and to assess the impact of the service on patient care. METHODS: Telephone interviews (n = 65) and a questionnaire survey (n = 296) were conducted with various types of user, in various Trust settings. Some non-users were also contacted. Selection of interviewees and questionnaire recipients was not random, and aimed to cover all groups of users representatively. RESULTS: Results show that policy goals were being delivered, with indications of changes to clinical practice, and improved clinical governance. Promotion, training and support needs to be extensive, and tailored to needs, but users are not always aware they need training. The sharing of passwords cast doubts on the reliability of some usage data. CONCLUSIONS: Digital health library services, delivered at the point of care, are changing the way some clinicians practise. A combination of qualitative and quantitative evaluation methods are needed to assess digital library services. 相似文献

The present study addressed girls’ (N = 127) early numerical and spatial reasoning skills, within the context of a critical environment in which these cognitive skills develop, namely their homes. Specifically, proximal links between distal family socioeconomic conditions and first-grade girls’ arithmetic and spatial skills were examined (mean age = 6.72 years; SD = .34). The proximal roles of two factors were considered: the general learning characteristics of girls’ homes, and the kinds of math and spatial learning activities in which girls participated. General quality of the home learning environment and specific math activities mediated the relation between family socioeconomics and girls’ arithmetic skills. In contrast, socioeconomics and home learning experiences were related to girls’ spatial skills indirectly only through their verbal skills; spatial activities were not proximal predictors of spatial skills. For both arithmetic and spatial skills, mothers’ spatial skills were a strong predictor. Future research and intervention implications of these findings are discussed. 相似文献

Recent models of attention deficit/hyperactivity disorder (ADHD) suggest that the association between achievement motivation and school performance may be stronger in children with ADHD than in typically developing children. Therefore, the present study investigated associations between achievement motivation and performance on language skills and mathematical thinking in children with ADHD (n = 23; M = 9.4 years, SD = 1.1 years; 78% boys) and two matched control groups, i.e., a clinical control group (children with related disruptive behavior disorders; DBD), and a non-clinical control group (NC). Results confirmed stronger associations between achievement motivation and performance on receptive language and mathematical thinking in children with ADHD than in NC. Specifically, performance of children with ADHD was equal to NC for highly motivated ADHD children. These results underscore the importance of achievement motivation as a more essential key factor in the performance of children with ADHD as compared to typically developing children. 相似文献

The use of drawings as representations of personal mental models or images is one method of analyzing personal beliefs. This article discusses the development of the Draw‐An‐Environment Test and Rubric (DAET‐R) for assessing the mental models or images of the environment held by pre‐service teachers. It also provides results of preliminary research using the DAET‐R to assess pre‐service teachers’ personal beliefs and understandings about the environment, as interpreted from their drawings. Results of this pilot study using the DAET‐R for scoring early childhood pre‐service teachers’ drawings of the environment suggest that the participants’ mental models of the environment are incomplete. Results of this study also show that the DAET‐R can provide information about pre‐service teachers’ beliefs about the environment useful to teacher educators in the development and delivery of environmental education. 相似文献

The present study monitored a student-centred educational anti-smoking intervention with fifth graders by focusing on their
cognitive achievement and intrinsic motivation. In order to assess the potential influence of the setting on self-directed
learning, the intervention was conducted in two different learning environments: a classroom-based group in class at school;
and an out-of-school group in an outreach setting at a youth camp. A control group didn’t experience any specific intervention.
Outcomes were assessed with an achievement test and the Intrinsic Motivation Inventory. Although in both learning settings
similar cognitive levels were achieved, the out-of-school group showed a larger decrease in cognitive achievement and lower
intrinsic motivation scores for interest and perceived choice. This empirical study adds new evidence to student-centred learning
schemes in different learning environments, especially in an interdisciplinary context. 相似文献

Traditionally, experiments on social learning (in both humans and nonhumans) involve dyads, with an experimenter or experimenter-trained
conspecific serving as the demonstrator and the participant as the observer. But social learning in nature often involves
multiple potential models, and the models themselves were once learners. We discuss our studies of social learning by adult
humans in interactive group settings in the absence of formal demonstrations by experimenters, which tracked transmission
over multiple learner generations. In these experiments, we found evidence for cumulative learning over generations. This
has allowed us to manipulate learning conditions in order to test hypotheses regarding the necessary conditions for cumulative
culture. We also report results from a further experiment using similar methods, which compared conditions of varying cohort
size. Participants were given the task to build a paper airplane to fly as far as possible. Contrary to expectations, there
was no advantage for larger cohort sizes, in terms of the cumulative effects observed. 相似文献

In this study we explored how dramatic enactments of scientific phenomena and concepts mediate children's learning of scientific meanings along material, social, and representational dimensions. These drama activities were part of two integrated science‐literacy units, Matter and Forest, which we developed and implemented in six urban primary‐school (grades 1st–3rd) classrooms. We examine and discuss the possibilities and challenges that arise as children and teachers engaged in scientific knowing through such experiences. We use Halliday's (1978. Language as social semiotic: The social interpretation of language and meaning. Baltimore, MD: University Park Press) three metafunctions of communicative activity—ideational, interpersonal, and textual—to map out the place of the multimodal drama genre in elementary urban school science classrooms of young children. As the children talked, moved, gestured, and positioned themselves in space, they constructed and shared meanings with their peers and their teachers as they enacted their roles. Through their bodies they negotiated ambiguity and re‐articulated understandings, thus marking this embodied meaning making as a powerful way to engage with science. Furthermore, children's whole bodies became central, explicit tools used to accomplish the goal of representing this imaginary scientific world, as their teachers helped them differentiate it from the real world of the model they were enacting. Their bodies operated on multiple mediated levels: as material objects that moved through space, as social objects that negotiated classroom relationships and rules, and as metaphorical entities that stood for water molecules in different states of matter or for plants, animals, or non‐living entities in a forest food web. Children simultaneously negotiated meanings across all of these levels, and in doing so, acted out improvisational drama as they thought and talked science. © 2009 Wiley Periodicals, Inc.

The article examines the importance of ‘emotional labour’ in the constitution of the ‘teacherly‐self’. Deriving from a research project on work and social identity, the article explores the ways teachers have negotiated the radical changes in the profession in recent years, and uses the notion of ‘teacher resilience’ to explore the ways teachers have reacted to the effects of neo‐liberal reforms to education; reforms that have powerfully impacted on the more child‐centred ways of working in the classroom and school environment. Using narrative analysis of the work‐life histories of these retired teachers, recorded using oral history methodology, the authors examine structures of feeling that turn on notions of emotional labour and commitment, resilience and loss in relation to the occupational identity of teachers. 相似文献

In recent years educational policy on gender and achievement has concentrated on boys' underachievement, frequently comparing it with the academic success of girls. This has encouraged a perception of girls as the “winners” of the educational stakes and assumes that they no longer experience the kinds of gender inequalities identified in earlier studies. However, trying to balance academic achievement with being seen as a “proper girl” presents girls with difficult challenges, particularly in terms of being accepted and approved of by classmates and securing the attention of teachers. This paper explores the views of a group of high achieving 12‐ to 13‐year‐old girls who indicate that being regarded as “clever” continues to be negotiated within acceptable frameworks of femininity. 相似文献

Research into expertise is increasing across a number of domains pertinent to sport. Whilst this increase is particularly apparent in coaching, a key question is how to identify an expert coach? Accordingly, this paper draws upon existing studies into expert coaches to address this issue; in particular, the criteria used to select expert coaches for research purposes and the methods used in expert coach research. Based on these data, we contend that the elements of expertise are not fully reflected within currently accepted criteria which, in turn, results in expert coaching research not necessarily identifying the appropriate individuals to study. The paper concludes with recommendations for more rigorous criteria for selecting expert coaches and highlights the associated implications for the future training and development of expert coaches. 相似文献
