The use of career information delivery systems in the states

Conclusion The ever increasing demands on guidance and counseling programs has added new responsibilities to the tasks of the counselor specifically in the area of career development. Along with this increase in responsibility, the issue of accountability has been added. Career information delivery systems assist the counselor in meeting the need for accurate, relevant occupational and educational information that can be disseminated in a timely efficient manner. Therefore, CIDS should be a vital part of all comprehensive career guidance and counseling programs.Mary Elizabeth McCormac is an Occupational Information System Specialist, National Occupational Information Coordinating Committee, Washington, D.C.     

Conditioning with taste as the CS in conditioned flavor preference learning

There appear to be unconditioned affective reactions to the four basic tastes: liking for sweet and salt and disliking for sour and bitter. We attempted to modify these reactions by pairing the tastes with calories and with sweeter tastes. Differing sucrose concentrations were ineffective in reversing the preference for salt over citric acid or for saccharin over quinine. We could, however, reverse the preference for salt over citric acid, producing an actual preference for sour over salt, by using sucrose and saccharin as the reinforcers. The initial reactions to tastes could also be modified by reducing the initial difference in affect produced by the tastes through mixing both tastes with sucrose.     

电子学习与远程教育的实践、创新、未来——第6届“Learning Futures Festival”在线国际会议综述

2011年4月第6届＂Learning Futures Festival＂在线国际会议召开。会议采用英国、美国、澳大利亚三个时区国家接力的方式完成。与会专家学者特别关注开放教育资源及Web2.0背景下的教育创新。未来10年全球高等教育面临巨大的增长需求,开放教育资源运动的推进,将可能出现开放教育资源大学。开放共享理念逐步深入人心,Web2.0在教育和企业领域的广泛应用将改变人们的学习和工作环境,学习者和企业员工应当提升自我的数字素养技能以激发自身的创新潜能。我国远程教育面临资源可重用性较低和开放性不足等问题,在今后的发展中应借鉴发展中国家远程教育院校和企业学习的成功经验,加强教育资源开放共享的程度,整合电子学习技术在远程教育中的创新应用,以满足学习者个性化的学习需求。     

Inter-Parietal White Matter Development Predicts Numerical Performance in Young Children

In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres.     

Disentangling the relationship between working memory and language: The roles of short-term storage and cognitive control

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition.     

The impact of action learning on analysis of occupation

Technology and millennials have created a shift in the world and how it operates. This impact has been experienced in the field of occupational therapy education. As a result of this paradigm shift, an analysis of effective teaching methodologies was carried out to assess the most effective way to engage the millennials in an analysis of occupation process, which is a critical foundation for effective critical thinking and clinical practice for occupational therapists. An action learning assignment was utilized to bridge this gap. The action learning assignment immersed the students in a safe learning environment that recreated many types of domains that needed to be analyzed. As a result, the students experienced first-hand the outcomes of effective and ineffective analysis and problem-solving during their action learning project. Therefore, the students were able to reflect and critically think through alternatives and hear about other students' projects. Overall, the action learning project yielded positive learning and engaging outcomes.
