Exploring Developmental Appropriateness of Multitouch Tables in Prekindergarten: A Video Analysis     

Jennifer Ward  Stephanie Branson  Megan D. Cross  Ilene R. Berson 《Journal of Research on Technology in Education》2016,48(3):227-238

This study explored how developmentally appropriate practices influenced the affordances of a multitouch surface in an early childhood classroom. Children, ages 4 to 5 years old, were videotaped while engaged in a storymaking application on a multitouch table. As a result of the study, we found that some challenges with the functionality undermined children's autonomous control. The researchers observed numerous instances of issues with control of the medium, including height of the table, sensitivity to multiple types of touch, and limited instructions and prompts. Implications for future research and practice are discussed.  相似文献   

A Process for Reviewing and Evaluating Generated Test Items     

Mark J. Gierl  Hollis Lai 《Educational Measurement》2016,35(4):6-20

Testing organization needs large numbers of high‐quality items due to the proliferation of alternative test administration methods and modern test designs. But the current demand for items far exceeds the supply. Test items, as they are currently written, evoke a process that is both time‐consuming and expensive because each item is written, edited, and reviewed by a subject‐matter expert. One promising approach that may address this challenge is with automatic item generation. Automatic item generation combines cognitive and psychometric modeling practices to guide the production of items that are generated with the aid of computer technology. The purpose of this study is to describe and illustrate a process that can be used to review and evaluate the quality of the generated item by focusing on the content and logic specified within the item generation procedure. We illustrate our process using an item development example from mathematics drawn from the Common Core State Standards and from surgical education drawn from the health sciences domain.  相似文献   

科学技术支撑酒店安全的作用机制与保障体系研究     

林军华 《闽江学院学报》2011,32(6):77-81

信息资讯技术的飞跃式发展对现代酒店安全管理提出了巨大的挑战,特别是酒店安全问题越来越受到旅游者的重视,由于显性和隐性的安全隐患来源渠道广泛,使得酒店安全控制与管理变得更为复杂和困难,同时也对酒店安全管理的科技支撑提出越来越高的要求。鉴于此,我们应从酒店安全管理实践的角度出发,对酒店安全管理和科学技术支撑的内在共生性进行分析,构建科学技术支撑酒店安全的作用机制模型,并进一步完善科学技术支撑酒店安全的保障体系,以期能够为酒店安全管理和控制提供一定的借鉴意义,从而促进酒店业的健康、稳定和持续发展。  相似文献

论非政府科技奖励与自主创新战略的互动关系     

徐顽强  熊小刚 《科学技术与辩证法》2010,(6):103-107

自主创新战略是建设创新型国家的重要战略部署,非政府科技奖励是国家科技奖励体系的重要组成部分,是国家实施科技管理的重要政策工具。自主创新战略是非政府科技奖励蓬勃发展的外在推力,非政府科技奖励则是深化自主创新战略的重要途径。非政府科技奖励可以通过强化重点激励自主创新的政策导向,规范和加强奖项的运行及管理,加大对个人的奖励力度,重视奖项的品牌建设等措施来进一步推动自主创新战略的实施。  相似文献

Challenges of assuring the development of graduate attributes in a Bachelor of Arts     

K. Fraser  T. Thomas 《高等教育研究与发展》2013,32(4):545-560

All universities in Australia are asked to develop various attributes in their degrees. From 2011, the Australian Qualifications Framework has stipulated some of these attributes for the various levels of qualifications. There are many challenges that face assuring the development of graduate attributes in a Bachelor of Arts as the degree typically has very few core units (if any), a wide choice of subjects, a limited prerequisite structure and, unlike many professional degrees, the BA does not have an external accrediting body. This paper describes an approach used to identify the pathway undertaken by each individual student in a History major of the Bachelor of Arts. This pathway was used to identify the graduate attributes that each student should have developed, as articulated by the lecturers. Student perceptions were then compared with the graduate attributes that were intended to be developed through each individual's combination of units studied. In summary, through analysing the two methods (student perceptions and unit pathway) we found that they concurred with respect to only three-quarters of the graduate attributes. Possible reasons for the discrepancies and future research are discussed. The need for multiple methods of providing evidence of the development of graduate attributes is confirmed.  相似文献   

HIGH TECHNOLOGY,EMPLOYMENT AND THE CHALLENGES TO EDUCATION     

《普罗米修斯》2012,30(2):315-330

The contribution of employment in high technology industry to future employment growth in the US economy is estimated to be small. Much high technology employment is not professional work at all, but routine labour, and much of that performed by minority groups with few career opportunities. Most new jobs will occur in occupations requiring no more than secondary education. High technology may generate employment in other areas, but often low grade work performed in the “homework economy”. Appropriate education for employment in high technology industry and in computer-related fields is not necessarily specialised and technical; high-quality general education is probably more important. Instrumental education, ignorant of the demands of high technology, and of the demands a modern economy makes upon high technology, is likely to be counter-productive. Commercial and technical success requires a combination of cultural learning and technical skill.  相似文献
