Framing of transitional pedagogic practices in the sciences: enabling access

Educational literature shows that students from working-class backgrounds are significantly less likely to persist to completion in higher education than middle-class students. This paper draws theoretically and analytically on Bernstein’s ([1990. Class, Codes and Control, Volume IV: The Structuring of Pedagogic Discourse. London: Routledge; 2000. Pedagogy, Symbolic Control, and Identity: Theory, Research, Critique. Lanham: Rowman and Littlefield]) thesis that, through differential framing of pedagogic practices, the curriculum has capacity to accommodate all groups of students. Pedagogic practices in both a science foundation course and four first-year mainstream science courses in a higher education institution in the South African context are examined. Whilst the foundation course exhibits modalities that generally favour access, the mainstream courses have some modalities that appear to be constraining. It is argued from a social justice perspective that holistic curriculum transformations that better enable epistemic transitions are an urgent imperative, and that consideration of differential framing of pedagogic modalities offer a close-up empirical means of conceptualising such reforms.

Remote access laboratories in Australia and Europe

Remote access laboratories (RALs) were first developed in 1994 in Australia and Switzerland. The main purposes of developing them are to enable students to do their experiments at their own pace, time and locations and to enable students and teaching staff to get access to facilities beyond their institutions. Currently, most of the experiments carried out through RALs in Australia are heavily biased towards electrical, electronic and computer engineering disciplines. However, the experiments carried out through RALs in Europe had more variety, in addition to the traditional electrical, electronic and computer engineering disciplines, there were experiments in mechanical and mechatronic disciplines. It was found that RALs are now being developed aggressively in Australia and Europe and it can be argued that RALs will develop further and faster in the future with improving Internet technology. The rising costs of real experimental equipment will also speed up their development because by making the equipment remotely accessible, the cost can be shared by more universities or institutions and this will improve their cost-effectiveness. Their development would be particularly rapid in large countries with small populations such as Australia, Canada and Russia, because of the scale of economy. Reusability of software, interoperability in software implementation, computer supported collaborative learning and convergence with learning management systems are the required development of future RALs.     

论民族关系和谐视阈下的教育公平

经济社会发展滞后区域与少数民族集中分布地区的重合,决定了教育公平缺失现状对我国民族关系和谐发展的消极影响。它限制、削弱了民族地区和少数民族个体成员自我发展、参与竞争的能力,阻碍着民族间事实上平等的实现和民族团结的进一步发展。因此,在构建社会主义和谐社会的时代背景下,必须从民族关系和谐视阈考察、应对教育公平缺失问题。为此,一要加大民族教育立法、执法力度;二要以政府为主、多种途径增加教育投入;三要完善民族教育优惠政策,增强民族互助。

基于粒度概念分析法的文献关键词分析——以Ontology领域关键词为例

以概念格理论为基础,在形式概念分析的基础上,提出以粒度概念分析(GCA)的方法进行文献关键词分析,并针对Ontology领域开放存取文献的关键词,构建不同粒度概念格。通过基于粗细不同粒度概念格的挖掘,对Ontology领域相关文献进行领域高频关键词和相关低频关键词的分析,从而揭示和呈现Ontology领域相关知识的结构和内在关联,以期探索一种基于概念格的文献关键词分析的新途径。     

日本共享知识库的调查与分析

对于那些难以构建自身独立机构知识库的中小规模的学术机构来说,共享知识库的构建更显经济和有效。文章对日本共享知识库的基本情况、成员机构、经费来源、内容建设等进行了调查和分析。调查结果发现,日本的共享知识库的发展得益于日本国立情报学研究所的经费投入和技术支持,主办机构构建自身独立知识库的经验等等。同时,也发现了日本共享知识库一些问题或不足。

数据密集型科学环境中科技期刊的数字化走向

数据爆炸促成了科学研究模式的转化,使科学研究过程成为以收集数据一分类处理数据一分析数据为主的”数据密集型”研究。新的科学研究范式对数据的需求是跨学科、跨地域、跨类型的数据大融合,因此各种数据基础设施应运而生。面对这样的改变,科技期刊的应对策略是尽快实现全面数字化、全面开放,推进文献数据的结构化,逐步实现与其他数据基础设施和各种类型科学数据的融合。
