The context of this study were research and development projects in Dutch secondary education, particularly funded by government to combine practice-based research with school development goals for inquiry-based culture. Aiming at better understanding of the strategic role that school leaders play in embedding inquiry-based practices in schools, the research question of this study was to explore to what extent and how do school leaders use the opportunity of participating in funded research and development projects for encouraging and integrating inquiry-based practices in their schools? Differences concerning the integration of inquiry-based working in the school as professional learning community were examined, distinguishing between school leaders’ strategies of capacity building. Twenty-eight school leaders of Dutch secondary schools, involved in nineteen projects, were interviewed retrospectively. Analyses showed the majority of the school leaders to be convinced that inquiry-based working is important for their schools’ development as a professional community. Their strategies for achieving school level project significance differed in school leaders’ successive attention on personal or interpersonal capacity building with regard to inquiry-based practices. Moreover, while some school leaders were actively involved with capacity building right from the start of the research and development projects projects, almost two-third of the school leaders developed interest in inquiry-based practices during the projects and started to enact in the final year of the project. In discussing the results, it is proposed that the interaction of strategy and context needs further study, for instance to inform peer learning among school leaders that are novice and experienced in inquiry-based practices as a means to develop the school as a professional learning community. 相似文献

A crucial challenge in measuring how text represents an entity is the need to associate each representative expression with a relevant entity to generate meaningful results. Common solutions to this problem are usually based on proximity methods that require a large corpus to reach reasonable levels of accuracy. We show how such methods for the association between an entity and a representation yield a high percentage of false positives at the expression level and low validity at the document level. We introduce a solution that combines syntactic parsing, semantic role labeling logic, and a machine learning approach—the role-based association method. To test our method, we compared it with prevalent methods of association on the news coverage of two entities of interest—the State of Israel and the Palestinian Authority. We found that the role-based association method is more accurate at the expression and the document levels. 相似文献

User generated content forms an important domain for mining knowledge. In this paper, we address the task of blog feed search:
to find blogs that are principally devoted to a given topic, as opposed to blogs that merely happen to mention the topic in
passing. The large number of blogs makes the blogosphere a challenging domain, both in terms of effectiveness and of storage
and retrieval efficiency. We examine the effectiveness of an approach to blog feed search that is based on individual posts
as indexing units (instead of full blogs). Working in the setting of a probabilistic language modeling approach to information
retrieval, we model the blog feed search task by aggregating over a blogger’s posts to collect evidence of relevance to the
topic and persistence of interest in the topic. This approach achieves state-of-the-art performance in terms of effectiveness.
We then introduce a two-stage model where a pre-selection of candidate blogs is followed by a ranking step. The model integrates
aggressive pruning techniques as well as very lean representations of the contents of blog posts, resulting in substantial
gains in efficiency while maintaining effectiveness at a very competitive level. 相似文献

Based on a review of research and the realities of performance information utilization in public organizations, this article defines the use of performance information as an organizational routine in management control. The theoretical implications require scholars to focus on organizational routines in performance measurement research. To practitioners, it suggests that they should focus more on daily performance information use and view it as continuous organizational learning and an organizational behavior modification process. 相似文献

There is an increasing call for preventive state interventions in so‐called families at risk—that is, interventions before any overt harm has been done by parents to their children or by the children to a third party, in families that are statistically known to be liable to harm children. One of the basic principles of liberal morality, however, is the citizen's right to be free from state intervention so long as no demonstrable harm has been done. On the other hand, Joel Feinberg interprets the harm principle as a harm prevention principle, so that the risk of harm also might be a reason for interference. The question that needs to be asked, therefore, is whether enforced preventive intervention in the cases where families are judged to be at risk can be justified within the limits of liberalism. 相似文献

Computer modeling – creating executable modelsof science domains – has been recognized as animportant teaching method. Still not much isknown about the factors making modelingenvironments effective in use. We investigatethe effect of different externalrepresentations on the construction of computermodels. Representations can significantlyinfluence the processes of modeling. In orderto find the specific benefits of two differentrepresentations, we compare dyads working on acollaborative modeling task using a text-basedmodel representation, in which correctequations are required to make the model run,with others using a graphical representation,in which the model is built by qualitativelylinking variables. The learners, secondaryschool students and modeling novices, workedwith the representations on a task in thedomain of physics. Results indicate that thetwo representations induce differentbehaviours, which are appropriate for differentphases of the modeling process. 相似文献

This article explores what it means for teachers to engage in and evaluate students’ character education, by examining the connections between action research and Aristotelian virtue ethics. These connections are explored in two ways. Firstly, the article examines what perspective action research has on how moral education, understood in an Aristotelian way, can be implemented and evaluated. While character education may be hot in educational theory, academic advances have not always reached teachers, heads of school, policy-makers and politicians. Secondly, a specifically Aristotelian approach to action research is explored that may help teachers to understand how action research about character education in schools can best be conducted. After a comparison of the three major action research paradigms, ‘Aristotelian action research’ is described as a kind of dialogical enquiry that contributes to the growth of teachers’ practical wisdom, which, in turn, has an effect on children’s character development. The article ends with suggestions as to how research about character education could be improved if we shift our attention from making character programmes more ‘effective’ to extending and refining teachers’ own practical wisdom and virtue. 相似文献

While many researchers in science education have argued that students’ epistemological understanding of models and of modelling processes would influence their cognitive processing on a modelling task, there has been little direct evidence for such an effect. Therefore, this study aimed to investigate the relation between students’ epistemological understanding of models and modelling and their cognitive processing (i.e., deep versus surface processing) on a modelling task. Twenty‐six students, working in dyads, were observed while working on a computer‐based modelling task in the domain of physics. Students’ epistemological understanding was assessed on four dimensions (i.e., nature of models, purposes of models, process of modelling, and evaluation of models). Students’ cognitive processes were assessed based on their verbal protocols, using a coding scheme to classify their types of reasoning. The outcomes confirmed the expected positive correlation between students’ level of epistemological understanding and their deep processing (r = 0.40, p = .04), and the negative correlation between level of epistemological understanding and surface processing (r = ?0.51, p = .008). From these results, we emphasise the necessity of considering epistemological understanding in research as well as in educational practice. 相似文献

Science Created by You (SCY) learning environments are computer-based environments in which students learn about science topics in the context of addressing a socio-scientific problem. Along their way to a solution for this problem students produce many types of intermediate products or learning objects. SCY learning environments center the entire learning process around creating, sharing, discussing, and re-using these learning objects. This instructional approach requires dedicated instructional designs, which are supplied in the form of what are called pedagogical scenarios. A SCY pedagogical scenario presents the learning process as an organized assembly of elementary learning processes, each associated with a specific learning object and a tool for creating this learning object. Designing a SCY learning environment is basically a two-step procedure: the first step is to select one of the available scenarios, and the second step is to define the domain content. The SCY technical infrastructure then handles the instantiation of the scenario as a SCY computer-based learning environment. In this article we describe the SCY pedagogical design scenarios and report on our experiences in designing four different SCY learning environments. 相似文献

Regulation of the learning process is an important condition for efficient and effective learning. In collaborative learning,
students have to regulate their collaborative activities (team regulation) next to the regulation of their own learning process
focused on the task at hand (task regulation). In this study, we investigate how support of collaborative inquiry learning
can influence the use of regulative activities of students. Furthermore, we explore the possible relations between task regulation,
team regulation and learning results. This study involves tenth-grade students who worked in pairs in a collaborative inquiry
learning environment that was based on a computer simulation, Collisions, developed in the program SimQuest. Students of the
same team worked on two different computers and communicated through chat. Chat logs of students from three different conditions
are compared. Students in the first condition did not receive any support at all (Control condition). In the second condition,
students received an instruction in effective communication, the RIDE rules (RIDE condition). In the third condition, students
were, in addition to receiving the RIDE rules instruction, supported by the Collaborative Hypothesis Tool (CHT), which helped
the students with formulating hypotheses together (CHT condition). The results show that students overall used more team regulation
than task regulation. In the RIDE condition and the CHT condition, students regulated their team activities most often. Moreover,
in the CHT condition the regulation of team activities was positively related to the learning results. We can conclude that
different measures of support can enhance the use of team regulative activities, which in turn can lead to better learning
results. 相似文献
