运用“增值”评量指标评估学校表现

运用“增值”评量方法能增强学校效能评估的效度,同时也为教育评估提供了有关的新理念。进行“增值”评量时,有必要收集学生的学习成绩、学生的学习能力基线、学校背景和情境信息、学校教育环境信息等。在研究学校效能的领域里比较常用的几种统计分析方法各有其优缺点。为得到学校的真实情况,需要分析不同类型“增值”评量指标。有关人员需了解“增值”评量方法的局限性,以做到有效使用。一个旨在促进学校评价方法创新和学校教学质量提高的中一英合作“增值”评量试验项目正在中国进行。     

Genetic etiology of spelling deficits in the Colorado and London twin studies of reading disability

The basic multiple regression model for the analysis of selected twin data (DeFries and Fulker 1985, 1988) was fitted to spelling data from 100 pairs of MZ twins and 71 pairs of same-sex DZ twins tested in the Colorado Reading Project (DeFries, Olson, Pennington and Smith 1991), and to data from 12 pairs of MZ twins and 15 pairs of same-sex DZ twins tested in the London twin study of reading disability (Stevenson, Graham, Fredman and McLoughlin 1984, 1987). Estimates of h _g ² obtained from analyses of these data suggest that about 60% of the deficit of probands is due to heritable influences in both samples. When a regression model was fitted separately to data from males and females in the combined Colorado and London samples, resulting estimates of h _g ² were 0.66±0.18 and 0.56±0.19, respectively, a nonsignificant difference. Collaborative analyses of data from additional twin studies of reading disability would facilitate more rigorous tests of hypotheses of differential genetic etiology as a function of group membership.     

An Australian study of possible selves perceived by undergraduate engineering students

In this study, we worked with second-year engineering students at an Australian university to examine previously identified threshold concepts within the theoretical framework of Possible Selves. Using workshops as the context for intensive work with students, students were encouraged to consider their future lives and work, including their engineering fears, expectations, and aspirations. The findings revealed many students to have a poor understanding of the realities of engineering work. Moreover, perceived gaps between self-efficacy and the requirements of engineering work appeared to be motivating if students deemed it possible to reduce the gap, but demotivating if they identified a characteristic over which there was perceived to be no control. The study suggests that these engineering students needed more opportunities to explore both the roles of engineers and their own possible selves. Overall, the findings indicate that higher education students may need encouragement and support to explore potential future roles, and they strengthen calls for further research in this area.     

Story Nights: an apprenticeship into literacy through bilingual story reading

This article documents an extended Mexican family’s social practices surrounding literacy as they engage with bilingual children’s literature in a unique context that draws from both home and school without the pressures of curriculum mandates. The research is situated within the southeastern United States where English-dominant practices permeate the school and community. Sociocultural and third space theories provide a framework for understanding the complexities surrounding language use and literacy development. Findings indicate the new space, Story Nights, provides for the development of connections to Mexican culture and a notion of community-based literacy learning. The author makes recommendations for classroom teachers, teacher education programs, and educational policy to be more inclusive of Latino/Latina English learners.     

To promote,or not to promote fundamental British values? Teachers’ standards,diversity and teacher education

In this article we seek to problematize the presence of the requirement within the teachers’ standards (DfE, 2012), that they ‘should not undermine fundamental British values’ in the context of initial teacher education in England. The inclusion of this statement within the teachers’ code of conduct has made its way from the counter‐terrorism strategy, Prevent and raises questions about Britishness, values and the relationship between the state and the profession more generally. We argue that the inclusion of the phrase within a statutory document that regulates the profession is de facto a politicization of the profession by the state thereby instilling the expectation that teachers are state instruments of surveillance. The absence of any wider debate around the inclusion of the statement is also problematic as is the lack of training for pre‐service and inservice teachers since it means this concept of fundamental British values is unchallenged and its insidious racialising implications are unrecognised by most teachers.

Result merging methods in distributed information retrieval with overlapping databases

In distributed information retrieval systems, document overlaps occur frequently among different component databases. This paper presents an experimental investigation and evaluation of a group of result merging methods including the shadow document method and the multi-evidence method in the environment of overlapping databases. We assume, with the exception of resultant document lists (either with rankings or scores), no extra information about retrieval servers and text databases is available, which is the usual case for many applications on the Internet and the Web. The experimental results show that the shadow document method and the multi-evidence method are the two best methods when overlap is high, while Round-robin is the best for low overlap. The experiments also show that [0,1] linear normalization is a better option than linear regression normalization for result merging in a heterogeneous environment.

Shaping Up: Boot Camp and Other Programs Addressing Professional Development Needs of Science Librarians

Scientists work collaboratively with online tools, relying almost exclusively on online resources and sharing publications freely online while generating and utilizing large datasets. As a result, librarians charged with providing services to the scientific community face both opportunities and challenges in keeping up in this electronic, digital environment. To meet these challenges, library leaders from the five campuses of the University of Massachusetts System established an on-going e-Science initiative. This initiative focuses on increasing awareness and understanding of the principles of e-Science while improving general knowledge within different scientific disciplines. Programs of varying lengths and focus provide local and affordable professional development opportunities that improve the working librarian's ability to better serve scientific researchers and students.
