Using a modified argument-driven inquiry to promote elementary school students’ engagement in learning science and argumentation

This study explored the effects of a modified argument-driven inquiry approach on Grade 4 students’ engagement in learning science and argumentation in Taiwan. The students were recruited as an experimental group (EG, n?=?36) to join a 12-week study, while another 36 Grade 4 students from the same schools were randomly selected to be the comparison group (CG). All participants completed a questionnaire at the beginning and end of this study. In addition, four target students with the highest and the other four students with the lowest pretest engagement in learning science or argumentation to be observed weekly and interviewed following the posttest. Initial results revealed that the EG students’ total engagement in learning science and argumentation and the claim and warrant components were significantly higher than the CG students. In addition, the EG students’ anxiety in learning science significantly decreased during the study; and their posttest total engagement in learning science scores were positively associated with their argumentation scores. Interview and observation results were consistent with the quantitative findings. Instructional implications and research recommendations are discussed.     

富氧条件下CuO/TiZrO4催化还原NO的研究

用共沉淀法制备TiZrO4复合氧化物，并作为载体。采用等体积浸渍法担载CuO制成CuO／TiZrO。催化剂，考察其在富氧条件下以CH4作还原剂催化还原NO的性能，研究了CuO负载量、反应温度对NO转化率的影响。结果表明CuO负载量为20％时催化活性最好，反应温度为200℃时，NO转化率可达65％。     

学生课堂参与的影响因素及方法研究

学生的课堂参与度已成为新课标下评价优质课的重要尺度。因此,以学生为本,提供学生参与的平台,提升课堂参与度,从而提高课堂效率已是广大教师面临的核心任务。为此,在教育教学中,教师可从学习兴趣、教学方法、教学技巧等方面入手来提升学生课堂参与度。     

幼儿园课程中的家长参与和家长发展

家长是基本的教育者，也是幼儿园课程的重要参与者。本文讨论了家长参与幼儿园课程的层次，认为家长是幼儿信息的提供者、幼儿活动的督促者、幼儿园课程材料的提供者、幼儿园活动的参与者、幼儿经验的提供者、幼儿园课程的审议者、幼儿园课程的评价者，并提出了家长在幼儿园课程实施过程中得到发展的可能性和途径。同时，对家长参与课程的现状进行了理性的分析。     

数据库的发布

当前，数据库技术在Internet／Intranet条件下发生了巨大的变化，数据库的网络应用和实现方式也在飞速发展。从传统的发布技术，到现在的B／S（Browser／Server）结构，再到新兴的自动发布技术，web数据库发布技术在逐步走向成熟。     

Multimedia and Online Video Case Studies for Preservice Teacher Preparation

Case studies have been used successfully as a part of teacher education. There are many possibilities in extending the impact of case studies through the use of technology. Video and the Internet could enable demonstration of more examples, dissemination beyond the walls of the classroom, and discussion between geographically dispersed preservice teachers. Several projects are now investigating the possible ways that technology might enhance or extend text case studies. After exploring four existing products, four essential elements for video case studies are proposed. As video case studies move to the Internet, additional issues arise and these are also explored.     

辛亥革命与中国政治现代化

辛亥革命具有政治现代化的特征,它是传统中国政治现代化的一种方式。辛亥革命推翻了东方的帝王专制,造就了中华民国,变更了中国政治统治的合法基础;在中国政治舞台上引进了国会、宪法和总统等西方的新制度文明,引起了政治结构的分化;开创了中国“宪政之治”的新传统,终结了传统中国“朝代国家”的型态,造成了政治文化的世俗化;彻底变革了传统社会的政治结构,增强了国家和社会的力量,带来了政治参与的扩大化。
