Hyperlab: A universal provider system and an interactive test bench for distance learning     

Kenny Stevens  Frank Appaerts  Ingrid Van Vlierberghe  J. Boutsen 《European Journal of Engineering Education》2002,27(1):49-61

This project describes the development of a universal student friendly distance learning (DL) provider system via the Internet and in particular the development of a lab environment for engineering students in ICT. Application of most DL courses is still hampered by the need for high-speed links, unrealistic computer and software resources at the student site and the impossibility to run Windows or Unix applications over the Internet. The described solution solves practically all of these problems. Moreover, since courses, (simulation) programs, databases, etc. can be added or changed, the system is not only teacher friendly but also costeffective. The major part of the work concerns the design of an electronic lab environment at the university that can be remotely used via the Internet. The main aim is to provide the student with meta-cognitive knowledge as can be provided only by real lab exercises. In this case the student must work him/herself through a course on passive filters. After choosing the right topology for the particular filter-lab task, he/she must design the correct circuit diagram and verify it with a standard circuit simulation program. Next, with a matrix shown on screen, he/she interconnects the circuit components and measuring equipment. The results of the measurements performed at the lab in the university are sent back to the student (via the Internet). The lab report is automatically generated. Simultaneously, the set up and the different instruments can be visualized via a web camera. Thus, the design of the electronic lab environment is user, student and teacher friendly.  相似文献   

运用“增值”评量指标评估学校表现   总被引：6，自引：0，他引：6  

萨丽·托马斯  彭文蓉 《教育研究》2005,(9)

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。  相似文献   

Have the shifting sands of Fordism resulted in ground lost or ground gained for distance education?     

Kay Stevens 《Distance Education》1996,17(2):247-266

Industrialisation and distance education make uncomfortable bed fellows. This article critically analyses the paths travelled by distance education when burdened by industrial sociology. The models for industrialisation, specifically Fordist and post‐Fordist ones, whether methodologically anchored in modernity or post‐modernity, are argued as having relevance only to the production aspects of distance education. The attempts of various authors in distance education over recent years to identify strong paradigmatic links between distance education and industrialisation have resulted in the qualities of distance education as an educational process being overlooked or rejected in favour of a supposedly more ‘open’ form of teaching and learning.  相似文献   

An information-processing analysis of children's accuracy in predicting the appearance of rotated stimuli   总被引：2，自引：0，他引：2  

R A Rosser  S S Ensing  P J Glider  S Lane 《Child development》1984,55(6):2204-2211

Children's ability to discriminate reflections and rotations of visual stimuli was examined using a kinetic imagery task. It was hypothesized that success would be related to the number and placement of orientation markers on the stimuli, as well as whether or not reflections had to be discriminated from simple rotations. 40 4- and 5-year-old children were directed to imagine how a stimulus would look if rotated to a specified location and asked to indicate the appearance of the reoriented stimulus by selecting the correct option from a number of foils. 48 of the items required only discrimination of a reoriented stimulus. The other 48 also required discrimination of a reflection of the reoriented stimulus. Stimuli differed in the number of orientation cues on the edges of the figures. Results revealed that prediction accuracy was associated with the existence of orientation markers on the stimuli, as well as age, sex, type of discrimination, and several interactions among the variables. Findings were discussed in comparison to a priori predictions based on an analysis of how children might use orientation information when performing mental rotation tasks.  相似文献   

Challenges facing child protection     

Lachman P  Poblete X  Ebigbo PO  Nyandiya-Bundy S  Bundy RP  Killian B  Doek J 《Child abuse & neglect》2002,26(6-7):587-617

The challenges facing children in the 21st century are immense and will need to be faced if we are to achieve the goal of child protection for all. Three specific constraints on child protection are examined in this article, namely poverty, HIV/AIDS infection, and war. The authors use their experience in Africa to raise issues of resilience and adaptation, dangers to child protection programs, and possible solutions. Poverty can be both financial and psychological, and this affects the effect of prevention programs. In many African and Asian countries, the AIDS pandemic has changed the social structure of society with AIDS orphans and children infected and affected by HIV/AIDS becoming more common. The impact has devastating effects on the way we view child protection and in particular child sexual abuse. The consequences of post-traumatic stress resulting from war needs to be addressed, and the development of programs that place children in the center of relief programs to foster a culture of child protection is essential. Finally, the article notes that the picture is not overly pessimistic and the examines the achievements in the field of children's rights which underpin all programs aimed at protecting children and the future need to consolidate successes achieved.  相似文献   

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

J. C. Defries  Jim Stevenson  Jacquelyn J. Gillis  Sally J. Wadsworth 《Reading and writing》1991,3(3-4):271-283

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.  相似文献   

An Australian study of possible selves perceived by undergraduate engineering students     

Dawn Bennett  Sally A. Male 《European Journal of Engineering Education》2017,42(6):603-617

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.  相似文献   

Adaptations in the teaching of composition to non-native speakers of English     

Sally L. Chirinos  Suellen Rundquist  Lisa Washburn 《Innovative Higher Education》1982,6(3):184-192

This article defines the problem of teaching foreign students in standard American university composition courses. It describes how two composition courses were modified to meet the needs of students who were beyond English as a Second Language composition but not yet ready for mainstream study. The article suggests that adaptations, not only in technique, but in approach and content as well, are required in order to fulfill the needs of these special students.Sally L. Chirinos, M.A. was the Academic Director of the EFL Program at the Instituto Cultural Peruano-Norteamericano, Arequipa, Peru from 1977–78. Suellen Rundquist is a M.A. candidate in Foreign Language Education and English as a Second Language at the University of Minnesota. Lisa Washburn holds a M.A. in English as a Second Language and a M.A. Germanic Philology from the University of Minnesota.  相似文献   

Story Nights: an apprenticeship into literacy through bilingual story reading     

Sally Brown 《Teaching Education》2016,27(3):286-304

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.  相似文献   

Presenting Complex Teacher Evaluation Data: Advantages of Dossier Organization Techniques Over Portfolios     

Kenneth D. Peterson  Dannelle Stevens  Carol Mack 《Journal of Personnel Evaluation in Education》2001,15(2):121-133

The development of extensive and authentic teacher evaluation raises questions about how best to organize and present the increased amount and variety of assessment materials. Portfolios have been suggested for teacher evaluation because they are well suited to capture the complexities of teaching. However, portfolios 1) are difficult to judge, 2) are difficult to archive, 3) lack key information, 4) miss excellent teachers with simple materials, 5) rarely plan for audiences, 6) distort when required, and 7) bring conflicts of interest. Teacher dossiers are compressed collections of objective data which are easier to judge, demonstrably reliable, and cost-effective.  相似文献
