陕西省高职教育专业设置与产业结构适应性初探

首先介绍陕西省高职教育现状及其专业设置的情况,随之对陕西省高职教育的专业设置、陕西省三次产业以及八大支柱产业的适应性进行分析,论述高职专业设置与产业结构之间某些不协调之处,最后总结陕西省高职专业设置存在的一些问题,并提出相应的对策建议。     

Using data mining to predict K–12 students' performance on large‐scale assessment items related to energy

This article reports a study on using data mining to predict K–12 students' competence levels on test items related to energy. Data sources are the 1995 Third International Mathematics and Science Study (TIMSS), 1999 TIMSS‐Repeat, 2003 Trend in International Mathematics and Science Study (TIMSS), and the National Assessment of Educational Progress (NAEP). Student population performances, that is, percentages correct, are the object of prediction. Two data mining algorithms, C4.5 and M5, are used to construct a decision tree and a linear function to predict students' performance levels. A combination of factors related to content, context, and cognitive demand of items and to students' grade levels are found to predict student population performances on test items. Cognitive demands have the most significant contribution to the prediction. The decision tree and linear function agree with each other on predictions. We end the article by discussing implications of findings for future science content standard development and energy concept teaching. © 2007 Wiley Periodicals, Inc.

基于分布式的直方图检索方法研究及实现

基于内容的图像检索在检索效率和检索性能等方面一直存在着限制与不足。为提高图像检索效率,对基于内容的图像检索和分布式计算进行研究,提出一种基于图像颜色模型向直方图转换的分布式检索方法DHCIR(Distributed Image Retrieval method based on Color Model to Histogram Conversion),并基于该方法进行系统设计及实现。通过实际测试,该算法能够提供稳定、快速、高效的图像检索服务,提高图像检索的计算效率与准确性。     

USING RASCH MEASUREMENT TO VALIDATE THE INSTRUMENT OF STUDENTS’ UNDERSTANDING OF MODELS IN SCIENCE (SUMS)

Scientific models and modeling play an important role in science, and students’ understanding of scientific models is essential for their understanding of scientific concepts. The measurement instrument of Students’ Understanding of Models in Science (SUMS), developed by Treagust, Chittleborough & Mamiala (International Journal of Science Education, 24(4):357–368, 2002), has commonly been used to measure SUMS. SUMS was developed using the Classical Test Theory (CTT). Considering the limitations of CTT, in this study we applied a Rasch model to validate SUMS further. SUMS was given to 629 students in 18 classes of grades 9 and 10 from six high schools in China. The results present both additional evidence for the validity and reliability of SUMS and specific aspects for further improvement. This approach of validation of a published instrument by Rasch measurement can be applied to other measurement instruments developed using CTT.     

孙中山对传统文化的批判继承

处于中国近代社会急遽变革的时期,孙中山对中华传统文化进行了深刻的思考探索,提出了对今天弘扬中华传统文化依然富有价值的理论.孙中山认为,对中华传统文化要在分析、批判的基础上加以继承发扬,传统文化只有在结合当时的社会实践并与外来优秀文化交流中才能得到改造和发展.虽然,孙中山对中华传统文化中的封建因素批判得不彻底,甚至还有欣赏的成分,但他所提出的理论在当时则是独树一帜的.     

“教学、科研、基地三位一体”实验室管理模式的研究与实践

2003年山东农业大学园艺科学与工程学院实行"教学科研基地三位一体"实验室管理模式,依托国家重点学科、国家优秀博士后科研流动站等学科建设平台,实现了科研资源支持专业教学,提高了本科教育教学质量和实验室投资效益。     

从语用预设看记录片解说词的语用策略

解说词是纪录片中的重要元素,优秀的解说词可以为纪录片增加含金量。运用语用学的重要理论——语用预设,阐述了纪录片的解说词的语用策略,揭示了纪录片解说词是如何通过语用预设这一策略展开叙事背景、推动情节发展、以及巧妙地向观众传递潜在的信息等,从而达到画龙点睛的传播效果。     

古腾堡项目——数字图书馆的先驱者

古腾堡项目（ProjectGutenberg）被普遍认定是最早出现的数字图书馆。1971年7月4日,创始人MichaelHart将美国《独立宣言》输入计算机,开启了古腾堡项目的第一步。40年后,在Mr．Hard的领导和无数志愿者的帮助下,该项目的免费电子书等目前已经超过47Y本,而其附属网站收集的电子书更是超过了1077本。古腾堡项目作为最早的数字图书馆在数字图书馆发展史中扮演了十分重要的角色。文章对该项目的历史背景、信息资源组织、服务和技术特点等进行客观的介绍和评价。     

高职院校开展专业学位教育的理论矛盾和现实选择

从理论与实践两个方面分析了专业学位教育与高等职业教育的区别,认为高职院校原则上不宜开展专业学位教育,但极个别条件具备的高职院校可兼具实施高等职业教育和专业学位教育的功能.
