Internet‐based Science Learning: A review of journal publications     

Silvia Wen‐Yu Lee  Ying‐Tien Wu  Meng‐Jung Tsai  Tzu‐Chien Liu  Fu‐Kwun Hwang 《International Journal of Science Education》2013,35(14):1893-1925

Internet‐based science learning has been advocated by many science educators for more than a decade. This review examines relevant research on this topic. Sixty‐five papers are included in the review. The review consists of the following two major categories: (1) the role of demographics and learners' characteristics in Internet‐based science learning, such as demographic background, prior knowledge, and self‐efficacy; and (2) the learning outcomes derived from Internet‐based science learning, such as attitude, motivation, conceptual understanding, and conceptual change. Some important conclusions are drawn from the review. For example, Internet‐based science learning is equally favorable, or in some cases more so, to learning for female students compared to male students. The learner's control is essential for enhancing students' attitudes and motivation toward learning in Internet‐based science learning environments. Nevertheless, appropriate guidance from teachers, moderators, or the Internet‐based learning environment itself is still quite crucial in Internet‐based science learning. Recommendations for future research related to the effects of Internet‐based science learning on students' metacognitive reflections, epistemological development, and worldviews are suggested.  相似文献   

Evaluating the Comparability of Paper‐ and Computer‐Based Science Tests Across Sex and SES Subgroups     

Jennifer Randall  Stephen Sireci  Xueming Li  Leah Kaira 《Educational Measurement》2012,31(4):2-12

As access and reliance on technology continue to increase, so does the use of computerized testing for admissions, licensure/certification, and accountability exams. Nonetheless, full computer‐based test (CBT) implementation can be difficult due to limited resources. As a result, some testing programs offer both CBT and paper‐based test (PBT) administration formats. In such situations, evidence that scores obtained from different formats are comparable must be gathered. In this study, we illustrate how contemporary statistical methods can be used to provide evidence regarding the comparability of CBT and PBT scores at the total test score and item levels. Specifically, we looked at the invariance of test structure and item functioning across test administration mode across subgroups of students defined by SES and sex. Multiple replications of both confirmatory factor analysis and Rasch differential item functioning analyses were used to assess invariance at the factorial and item levels. Results revealed a unidimensional construct with moderate statistical support for strong factorial‐level invariance across SES subgroups, and moderate support of invariance across sex. Issues involved in applying these analyses to future evaluations of the comparability of scores from different versions of a test are discussed.  相似文献

The 'new' politics of education in Britain's changing times     

Jack Demaine 《International Studies in Sociology of Education》2013,23(2):115-128

The British Labour Party has continued to make progress on education, following two broad policy paths and adopting a pragmatic approach that does not attempt to force these to cross or converge. One path is that of the quasi market inherited from the previous Conservative administration; the other is characterised as 'intervention' to support those for whom the market remains almost entirely irrelevant. Some observers regard this dual approach as 'opportunism' and Labour's education policy as a 'betrayal' of principle, by which is meant the principle of 'equal opportunity'. Of course, that principle provides equal opportunity to fail as much as to succeed. Rather than leaving education to the market, Labour has focused on the needs of those most likely to be failed by the principle of 'equal' opportunity in a quasi market.  相似文献

Judgment‐Based Scoring by Teachers as Professional Development: Distinguishing Promises from Proof     

Gail Lynn Goldberg 《Educational Measurement》2012,31(3):38-47

The engagement of teachers as raters to score constructed response items on assessments of student learning is widely claimed to be a valuable vehicle for professional development. This paper examines the evidence behind those claims from several sources, including research and reports over the past two decades, information from a dozen state educational agencies regarding past and ongoing involvement of teachers in scoring‐related activities as of 2001, and interviews with educators who served a decade or more ago for one state's innovative performance assessment program. That evidence reveals that the impact of scoring experience on teachers is more provisional and nuanced than has been suggested. The author identifies possible issues and implications associated with attempts to distill meaningful skills and knowledge from hand‐scoring training and practice, along with other forms of teacher involvement in assessment development and implementation. The paper concludes with a series of research questions that—based on current and proposed practice for the coming decade—seem to the author to require the most immediate attention.  相似文献   

基于统计-规则方法的网页层次分类技术研究     

谭金波  杨晓江  李艺 《现代图书情报技术》2007,2(8):59-62

基于统计的自动分类是网页层次分类中常用的技术，但其有不足之处，主要表现为当子类之间出现严重的特征交叉现象时，分类精确率将大大下降。而网页层次分类的本质决定了同一大类下的子类存在许多相同的特征。针对这一局限性，结合基于规则的自动分类技术的优点，提出一种基于统计-规则方法的网页层次分类技术。实验表明，基于统计-规则方法的网页层次分类技术能够获得比较理想的分类效果。  相似文献
