In Iraqi Kurdistan, the educational system is going through significant changes. The educational system influences the students’ attitudes, and one wants the educational system to support the young democracy. In this study, student-centred learning (SCL) is seen as a first step to learning, but also to participation and engagement as a citizen. Three secondary school teachers worked with researchers from Norway and Kurdistan to implement SCL strategies in their daily teaching. Teachers experienced changes in their roles when emphasizing the importance of students’ participation in the learning processes. They could not lecture most of the time; they needed to make more space for the students’ activities and allow them to become more active. They acted more as mentors for their students. The content of the teaching also changed. When the teachers lectured it was about their subject. When the students were expected to be more active, the teachers also had to teach the students how to be more active. The traditional way of furnishing the classrooms in Kurdistan has been rows of benches and desks for the children and a desk by the board for the teacher. This way of furnishing was described as a hindrance when organising for students’ participation. The teachers’ experiences were of main interest in this action research project. Their responses to interview questions were validated by classroom observations. Also, a group of researchers with very different cultural and scientific background collaborated. This was in itself an interesting side effect in this action research study. 相似文献

This article provides background on national movements toward expanded school mental health (ESMH) programs and school‐based health centers (SBHCs), and presents advantages and challenges of joining these two systems of child and adolescent health care. Delivering ESMH through SBHCs promotes an interdisciplinary approach, health–mental health care integration, and benefits including enhancing referral bases, improving screening of problems, and enhanced confidentiality and privacy. But this integrated approach also presents challenges including managing referrals and significant needs, handling crises, building a focus on prevention and mental health promotion, handling administrative demands, and coping with limited resources. These challenges, ideas for overcoming them, and future directions for this promising service delivery approach are discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 297–308, 2003. 相似文献

This paper presents an evolutionary framework for horizontal technology policies (HTPs) especially market-friendly ones involving project-based incentives (e.g. R&D project based grants rather than tax-based incentives to yearly expenditures on R&D). HTPs are a category of technological policies whose objective is to promote technological development per se, and associated management and organizational routines, irrespective of industrial branch or technological area. They are being increasingly adopted by both advanced countries and newly industrialized countries in response to the new opportunities and threats opened up by the technological revolution and by the processes of liberalization and globalization; and they complement the more specific and well-known selective and vertical policies aimed at individual sectors and technologies. The analysis is conducted within a learning-to-innovate framework with emphasis on collective, organizational learning; search; and market-building. The outcome is a technology policy cycle with distinct infant, growth, and mature phases. Proactive ‘generation’ of a critical mass of projects for efficient learning and diffusion of innovation routines becomes the aim of the infant phase; while the mature phase of the policy should focus on policy restructuring including drastic reductions in the support of routi projects and enhanced support of more complex types of innovation. The paper also emphasizes the importance of a neutrality component in incentives in the infant phase of increasing selectivity; and of building policy capabilities for efficient policy design and implementation. 相似文献

A study of comprehensive schools in one English local education authority shows two Catholic schools at opposite ends of the effectiveness spectrum in helping pupils achieve examination success. Subsequent investigation of their understanding and interpretation of Catholic education finds them to represent two paradigms of Catholic school. Some possible causal relationships are explored between their values, attitudes and practices and their pupils' academic achievement. 相似文献

Previous studies explored the adoption of various information technologies. However, there is little empirical research on factors influencing the adoption of data mining tools (DMTs), particularly at an individual level. This study investigates how users perceive and adopt DMTs to broaden practical knowledge for the business intelligence community. First, this study develops a theoretical model based on the Technology Acceptance Model 3, and then examines its perceived usefulness, perceived ease of use, and its ability to explain users’ intentions to use DMTs. The model's determinants include 4 categories: the task-oriented dimension (job relevance, output quality, result demonstrability, response time, and format), control beliefs (computer self-efficacy and perceptions of external control), emotion (computer anxiety), and intrinsic motivation (computer playfulness). This study also surveys the moderating effect of experience and output quality on the determinants of DMT adoption and use. An empirical study involving 206 DMT users was conducted to evaluate the model using structural equation modeling. Results demonstrate that the proposed model explains 58% of the variance. The findings of this study have interesting implications with respect to DMT adoption, both for researchers and practitioners. 相似文献

The development of online and virtual teaching and learning environments to augment formal face-to-face environments raises questions about the way the new communication and information technologies (CITs) are being incorporated into the on-campus environment. More importantly, this development challenges the meaning of the on-campus student learning experience. The new CITs require institutions, teachers and researchers to reconsider the relationship of the physical setting to the student learning experience. This paper highlights examples of recent developments of new learning environments which have been enhanced by the contribution of educational developers at several Australian universities. It also proposes a set of pedagogically informed principles to guide the development of on-campus teaching and learning environments which may feature the use of CITs. 相似文献

The development and implementation of a new school‐based suicide prevention education programme in one secondary school in Vancouver, British Columbia, recently provided us with an opportunity to conduct an in‐depth, qualitative case study. The purpose of our study was to deepen our understanding of how school‐based suicide prevention education programmes like this one get planned and enacted in particular, local settings. We argue that the narrow range of methodologies that have traditionally been deployed to study school‐based youth suicide prevention education programmes have hindered our ability to see the complexities and potentialities of this work. Through the presentation of a sub‐set of findings, we aim to show the possibilities for fresh thinking and contextualized understandings that a qualitative case study, informed by a constructionist methodology, invites. 相似文献
