Joseph Priestley's soda water

This year is the 250th anniversary of the birth of Joseph Priestley. The occasion has been celebrated with many commemorative meetings and publications, swelling an already substantial and comprehensive literature devoted to his life and work. In this article marking the occasion the author has chosen to describe an interesting facet of Priestley's work which is not generally familiar.

Four dialogues and metalogues about the nature of science

We analyse and explore, in the form of dialogues and metalogues questions about the dialogic nature of beliefs and students belief talk about the nature of science and scientific knowledge. Following recent advances in discursive psychology, this study focuses not on students' claims but on the discursive resources and dialogical practices that support the particular claims they make. We argue that students' discourse is better understood as a textual bricolage that is sensitive to conversational context, common sense, interpretive repertoires, and textual resources available in the conversational situation. Our text is reflexive as it embodies the discursive construction of knowledge and undercuts any claims to authoritative knowledge. The very conception of “belief” is itself an expression or construction from within the mundane idiom.... We learn to use “belief” in conditions when the “objective facts” are unknown or problematic and we want to indicate the tenuous character of our claim.... The notion of “real world” or “objective reality” is embedded in an extensive, pervasive language game which includes as an intelligible move or possibility the use of the very concept of “belief” itself.

Criterion‐Related and construct validity of the pervasive developmental disorders rating scale and the autism behavior checklist

This study investigated the validity of the Autism Behavior Checklist (ABC; Krug, Arick, & Almond, 1993) and the Pervasive Developmental Disorders Rating Scale (PDDRS; Eaves, 1993a). Both instruments are screening devices designed to measure characteristics of individuals with autistic disorder or, more broadly, pervasive developmental disorders. Results showed that the total scores of the ABC and PDDRS measure significantly overlapping constructs (r= .80). Further, both instruments significantly discriminated between participants with autistic disorder and children with diagnoses frequently confused with autistic disorder. Both instruments provided respectable indices for classification accuracy (PDDRS overall accuracy = 88%, ABC overall accuracy = 80%). Finally, the ABC and PDDRS agreed in their classifications of 85% of the 136 participants; a phi coefficient based on the instruments' nominal classifications of the participants equaled .68 (p< .001). © 2000 John Wiley & Sons, Inc.     

The growing (but still limited) importance of evidence in education policy and practice

The last decade of education change has been characterized by the rise of evidence-based policy and practice agendas. Internationally, we are witnessing efforts to increase and incorporate research use in public services. This article examines efforts in education to address the research–practice gap through an emerging field we term knowledge mobilization (KM). We explore some of the controversy surrounding the use of ‘evidence’, outline national and international KM initiatives and consider some of the issues and challenges that arise from the increased interest in evidence and research use in education. We also assess the current state and desirable future directions of efforts to strengthen the role of research and evidence in education.     

一个标准能适合所有的项目吗:开放教育的选择

基于支持全英开放教育资源项目(英国开放教育资源项目,简称UKOER项目)的经验,本文将探讨该项目开展过程中所涌现出的各种不同的开放教育资源描述方法,及其对资源共享、工作流程计划、资源聚集观的影响.由于UKOUER项目包括个人层面的项目、学科层面的项目和院校层面的项目,而这三种类型的项目又有各自不同的特点,显然难以用一种技术或者描述性的解决方案来适合所有的项目.因此,目前这些项目只提供有限的描述性信息,包括项目标签、作者、题目、日期、链接地址、文件格式、文件大小、权限,以及一些附加信息,包括语言、学科分类、关键词、标签、评论和描述.所有项目可以自由选择编码、存储和分享上述信息的方法.本文通过大量的例证介绍了项目的描述方法,其中还包括工作流程和所作出的尝试.我们将考虑所选择的工具(资源库、Web2.0应用、虚拟学习环境)与标准选择的关系,以及本地需求和更广泛社区需求之间的关系.我们会考虑这些选择对资源传播和发现的影响,例如,资源描述对大量开放教育资源的发现服务的影响.     

Learning with Web Tools, Simulations, and Other Technologies in Science Classrooms

This position paper proposes the enhancement of teacher and student learning in science classrooms by tapping the enormous potential of information communication and technologies (ICTs) as cognitive tools for engaging students in scientific inquiry. This paper serves to challenge teacher-held assumptions about students learning science ‘from technology’ with a framework and examples of students learning science ‘with technology’. Whereas a high percentage of students are finding their way in using ICTs outside of school, for the most part they currently are not doing so inside of school in ways that they find meaningful and relevant to their lives. Instead, the pedagogical approaches that are most often experienced are out-of-step with how students use ICTs outside of schools and are not supportive of learning framed by constructivism. Here we describe a theoretical and pedagogical foundation for better connecting the two worlds of students’ lives: life in school and life outside of school. This position paper is in response to the changing landscape of students’ lives. The position is transformative in nature because it proposes the use of cyber-enabled resources for cultivating and leveraging students new literacy skills by learning ‘with technology’ to enhance science learning.     

The importance of interplay between school-based and networked professional development: School professionals’ experiences of inter-school collaborations in learning networks

Previous literature has demonstrated that networks can be valuable sources of professional learning. In 2005 all Liverpool schools formed into ten Learning Networks with the aim of improving the quality, and entitlement of, continuing professional development (CPD) for staff as part of a whole-scale local authority initiative. The Liverpool Learning Networks Research explored professionals’ CPD experiences following this organizational change and whether it has enhanced their practice. Triangulated data, a large-scale survey and qualitative interviews conducted in 2007, seem to suggest that where professionals benefited from professional learning in a networked context, the quality of the networked CPD as well as a positive school culture and intra-school collaboration were all important contributors to the success of networked-CPD. This finding can usefully apply Turbill’s (Teacher learning for educational change. Open University Press, Buckingham, 94–114, 2002) model of professional learning to the intersection between school-based and networked-CPD, which suggests that it is at this intersection between internal and external domains that teacher learning can take place. Two scenarios, where this interplay between school-based and networked CPD is positive (enhancement) or negative (tension), are reported through five case studies of professionals underpinned by the survey data, where relevant.
