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.     

Curriculum,pedagogy and assessment: three message systems of schooling and dimensions of quality physical education

This paper identifies ‘quality’ as an internationally relevant concept to be problematised in contemporary debates about physical education (PE). Drawing on the conceptualisation of curriculum by B. Bernstein in 1977, pedagogy and assessment as three inter-related message systems of schooling, the paper presents and explores curriculum, pedagogy and assessment as three fundamental dimensions of ‘quality PE’. Discussion addresses what quality in each dimension may mean in PE, and demand in practice. Contemporary initiatives in Australia and New Zealand provide a reference point for exploring the prospective application of quality conceptualised in terms of the three inter-related dimensions. Attention is drawn to frameworks in mainstream education that may be utilised in endeavours to critically review current practices, and inform developments directed towards achieving quality in PE. It is argued that achieving quality in PE requires that quality is pursued and demonstrated within and across curriculum, pedagogy and assessment, and that meanings of quality always need to be contextualised in cultural, social and institutional terms.     

Chinese number‐naming advantages? Analyses of Chinese pre‐schoolers' computational strategies and errors

Simplicity in number naming in a language (e.g. ‘ten‐two’ in Chinese is simpler than the irregular ‘twelve’ in English) has been used to explain cross‐cultural disparities in children's computational competence. In contrast to previous research focusing only on whether children can provide the correct answers, in this study (N?=?117 and 92) we examined Chinese pre‐schoolers' computational strategies in depth and individually so as to examine their understanding of the base‐10 system and place value. The results showed that despite the fact that many can give the correct answers, there is strong evidence that Chinese pre‐schoolers do not have adequate understanding of the base‐10 number system and place value, suggesting that the advantages of the simpler number‐naming system are limited.     

School district triggers for reconstructing professional knowledge

In a recent publication, Senge (All systems go: the change imperative for whole system reform. Corwin Press, Thousand Oaks, 2010, x) stated ??at no time in history has there been a more powerful need for a new vision of the purpose of education.?? Increasingly citizens, academics and practitioners are calling for radical changes to educational practices to meet the needs of a knowledge-based society in the twenty-first century (Dede in 21st Century skills: rethinking how students learn. Solution Tree Press, Bloomington, 2010; Hargreaves and Shirley in The fourth way: the inspiring future for educational change. Corwin Press, Thousand Oaks, 2009). Accomplishing such substantive educational change requires that individual educators collectively reshape their personal professional knowledge (Connelly and Clandinin in Teachers as curriculum planners: narratives of experiences. OISE Press, Toronto, 1988; Elbaz in Curriculum Inq 11(1):43?C71, 1981) and adapt their personal mental models (Duffy in J Staff Dev 24(1):30?C36, 2003). In 2000, we began a longitudinal study on the role of a school district in facilitating significant educational reform which required adaptations to individual and collective mental models of professional practice. Annually we conducted intensive interviews with a large sample of teachers, school and system administrators in this large Ontario, Canada school district. Recently, we conducted a retrospective analysis of these data collected in order to identify the conditions necessary for a large organization to support knowledge-creation and dissemination. In this paper, we identify three school district actions that triggered individual educators to challenge and reconstruct their professional personal practical mental models of the teaching and learning. First, improved student learning became the central focus of the school district. Second, the school district stressed and created opportunities for educators to collectively engage in professional dialogue about their practice. Third, the school district emphasized the importance of educators individually and collectively using evidence to assess whether their actions improved student learning.

Cognitive development in a secondary science setting

Observations were made of the progressive change in the cognitive development of 141 students over the course of their secondary education in an Australian private school. Cognitive development was measured in years 8, 10 and 12 usingBond's Logical Orerations Test. Rasch analysis of each of the data sets provided ability estimates for students in the year groups of 1993 (year 8), 1995 (year 10) and 1997 (year 12). Twenty-nine students from the year group of 1993 were tested on all three occasions. We analysed data from these 29 students in order to investigate the children's cognitive development across years 8, 10 and 12. We also examined the influence of the Cognitive Acceleration through Science Education (CASE)Thinking Science program on the cognitive development and scholastic achievement of these students. We found increased mental growth between years 8 and 10 for most students in theThinking Science cohort, which could not be predicted from their starting levels. There was a significant correlation between cognitive development and the scholastic achievement of these students. Although boys as a group were more advanced in cognitive development than girls in years 8 and 10, no difference was found in the rate of cognitive change based on sex up to year 10. However girls showed cognitive gains across years 10–12 which were not found in boys. The students who were new to the school also showed increased cognitive development in years 11 and 12. Students who had experienced theThinking Science course were more cognitively developed than students who joined the school after the intervention had taken place. This study supports the claim of Adey and Shayer that there is a relationship between cognitive development and scholastic achievement, even though we used different measures of cognitive development and scholastic achievement.
