The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students’ inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA.  相似文献   

The male–female gap in post-baccalaureate school quality     

《Economics of Education Review》2013

Women are less likely than men to earn degrees from high quality post-baccalaureate programs, and this tendency has been growing over time. I show that, aside from the biomedical sciences, this cannot be explained by changes in the type of program where women tend to earn degrees. Instead, sorting by quality within degree program is the main contributor to the growing gap. Most of this sorting is due to the initial choice in which program type to apply to. No gender differences in selection with respect to ability or program quality arise as students progress through the admissions, enrollment or persistence choices.  相似文献   

The impact of peer achievement and peer heterogeneity on own achievement growth: Evidence from school transitions     

《Economics of Education Review》2013

This paper estimates ability peer effects on achievement growth in reading and math. It exploits variation in peer characteristics generated at the transition from primary to secondary school in a sample of Berlin fifth-graders. As will be discussed in detail, this variation is exogenous in large parts. Results are similar for both achievement measures: pupils benefit from abler peers, but high-achievers do so to a smaller extent. The variance in peer skills has no impact on achievement growth – the corresponding estimates are negative, but insignificant.  相似文献   

Inclusion in Norway: a study of ideology in practice     

Annlaug Flem  Clayton Keller 《欧洲特需教育杂志》2013,28(2):188-205

The purpose of this research was to examine how Norway's ideology of inclusion is realized in Norwegian schools and school systems, and what factors work to support or hinder its implementation. Using semi-structured interviews, we obtained data from our informants at multiple levels in the Norwegian educational system in one municipality. Our data analyses focused on identifying themes that were shared by multiple informants, as well as retaining important points or perspectives from individuals. Generally all of the informants were positive towards the ideology of inclusion. The biggest difficulty facing its implementation seemed to be that of social integration. This was much more of a concern than curricular integration. Probably because of such challenges, schools still placed students in separate settings. Factors that affected inclusion included: characteristics of teachers, classroom environment, school climate, cooperation, support from people with competence, attitudes and resources.  相似文献

增强西部地区科技能力的机制创新研究   总被引：1，自引：0，他引：1  

李慧 《科学与管理》2010,30(5)

从中国东、中、西部几大地区的科技创新能力综合评价结果来看,西部地区与东部地区相比差距十分悬殊,这也是西部地区自我发展能力不强的原因之一。区域科技能力是一个地区持续发展的根本动力,因此,西部地区如何创新增强其科技创新能力的机制、政策显得非常重要。本文在对西部地区科技能力现状进行分析并与东中部地区对比后提出:西部地区今后应在投融资机制、社会管理体制、制度和环境建设、科技创新体系建设等方面全面创新。  相似文献   

以释义为手段促进高级英语教学     

谢民 《黑龙江科技信息》2012,(27):223

在《高级英语》教学过程中,非常重要的一个环节就是对于课文的释义(paraphrasing),也是每一课的重点及难点。释义的环节直接影响到学生对于段落及篇章的理解程度,也会不同程度地提高学生语言表达能力和写作能力。有效地使用这一教学方法,对于提高学生的理解力和语言应用能力有较大的促进作用。  相似文献
