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

Hsiang-Ting Chen  Hsin-Hui Wang  Ying-Yan Lu  Huann-shyang Lin 《International Journal of Science Education》2016,38(2):170-191

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.  相似文献   

如何建设和谐的高校领导班子   总被引：2，自引：0，他引：2  

卢铁城 《中国高教研究》2007,(2):1-4

建设和谐的高校领导班子,是建设和谐校园的前提,是培养高素质创新人才、出高水平科研成果和办好学校的基础。书记和校长、党群系统和行政部门,任务相同,目标一致,分工不同,职责有别,关键在于按党的民主集中制原则,实行党委集体领导,班子成员分工负责,制度为保障,监督要到位,达到“和而不同”,团结和谐。  相似文献   

政府在创业板市场设立中的角色探讨     

卢慧芳 《湖北成人教育学院学报》2001,(5):43-44

政府在创业板市场设立中究竟应扮演哪种角色一直是理论界争论的热点,本文从创业板市场的特征入手,并从政府角色不当的反面分析,得出政府应当弱化其干预职能,尤其是要减少直接干预,最后对政府在创业板市场设立中的角色提出一些可行性建议。  相似文献   

Design considerations for series hybrid active power filter     

Chen Guo-zhu  Lu Zheng-yu  Qian Zhao-ming 《浙江大学学报(A卷英文版)》2001,2(3):313-317

Some important factors for designing a series hybrid active power filter (SHAPF) are presented in this paper for the case when the load is varied in a wide range and/or the source voltage is seriously distorted. Special design of passive filters, adaptive control of parameter and multi variant control are discussed in detail. The filter is stable, has good performance, and causes small capacitive reactive current. The simulation and experimental results accorded with the theoretical analysis results.

《六书故》引唐本《说文》"械"篆试析     

卢凤鹏 《毕节学院学报》2003,21(2):89-91

明清以来,治《说文》者屡次转引戴侗《六书故》中所引的唐本《说文》来考释文字.可见《六书故》所引唐本《说文》有其重要的文字学价值.通过考证,认为《六书故》引唐本《说文》"械"篆的"或说内盛为器,外盛为械"非许慎《说文》之原说解,只可作训读《说文》之佐证.  相似文献   

DIELECTRIC STUDIES OF UREASE AS A FUNCTION OF HYDRATION     

陆祖宏  Ronald Pethig  韦钰 《东南大学学报》1989,(2)

The steady-state electrical conductivity,as well as the dielectric propertiesbetween 2×10~(-4)Hz and 100 kHz,and at 1 GHz,are reported for urease compressed powdersamples of low hydration.The results show that the large,low frequency dielectricdispersion,known as α-dispersion,is due to the build-up of a space charge of protons atthe sample-electrode interfaces.A smaller dispersion,appearing at higher frequencies,isconcluded to be associated with hindered motions of the peptide residues in the molecularstructure of urease.The extent of these polypeptide backbone motions is shown to bestrongly depended on the extent of enzyme hydration.This work is contributed to the de-velopment of conductimetric biosensors.  相似文献   

光学分层成像法重建火焰温度场的理论和实验研究     

汪凤林  王式民  陆勇 《东南大学学报》2001,17(2)

提出了一种测量三维火焰温度的新方法 .根据光学分层成像理论 ,三维火焰可以看成若干个互相平行的二维发光断层的组合 .用高速摄像控制系统沿着某一固定方向对火焰进行分层聚焦摄像 ,得到一组辐射图像 ,每个图像都是其对应断层的聚焦像和其它断层离焦像的叠加像 ,运用图像反演算法 ,即可重建各断层的原始图像 ,再用彩色三基色测温方法 ,处理所得到的原始图像 ,即可建立火焰的三维温度场 .通过蜡烛火焰的试验 ,验证了该方法的可行性  相似文献   

论孙中山外援思想演变的历史轨迹及成因     

陆发春  黄文治 《五邑大学学报(社会科学版)》2007,9(1):6-10

孙中山是伟大的民主革命先行者，也是中外友好的使者。为促进中国民主革命的胜利，奔波域外，寻求外援，成为其革命生涯的重要特征。外援思想是孙中山思想中重要而又特殊的部分。孙中山寻求外援目的地由欧美——日芩——苏俄的历史演变，孕育着深刻的历史内涵，也从-侧面反映了中国民主革命的曲折历程。  相似文献   

楞次定律CAI课件的设计     

钱忆平  卢达  陈海鹏 《常熟理工学院学报》2002,16(4):89-92

在当前的素质教育中，多媒体CAI辅助教学运用日趋广泛，并在教学中起着重要的作用。但作为多媒体CAI的开发者，必须考虑多媒体CAI的设计原则以及哪些内容需要用课件来表达。不应盲目去追求多媒体CAI课件，而是要结合课堂教学的需要，有选择的进行此项工作。本文结合楞次定律课件的设计加以分析。  相似文献
