The purposes of this study were to investigate students’ conceptual learning outcomes and the effect of motivation on students’ conceptual learning outcomes in two different contexts: a Web-based and a classroom-based instruction, which incorporated the Dual Situation Learning Model (DSLM). Nine classes of Grade eight students (N = 190) were involved in the study; five classes participated in a Web-based context and four classes in a regular classroom-based context. The topic covered was chemical reaction. Students’ conceptual change outcomes were assessed using eight two-tier pre/post conceptual tests during the instruction and the reaction rate integrated conceptual test at the end of the instruction. Students’ motivation data were collected in the beginning and during instruction using the items from the Students’ Motivation Toward Science Learning (SMTSL) questionnaire. The data were analyzed using ANOVA, ANCOVA, bivariate correlation, and multiple regression analysis. Findings revealed that students’ motivational factors were correlated significantly with their conceptual learning outcomes in both Web-based and classroom-based science teaching. In the Web-based context, students’ motivation during the Web-based learning played a more important role on students’ conceptual learning outcomes than before learning.  相似文献

A new linearly-combined bi-exponential model for kinetic analysis of the isometric relaxation process of <Emphasis Type="Italic">Bufo gastrocnemius</Emphasis> under electric stimulation in vitro     

Guo R  Li SB  Zhao LN  Zhao YS  Lu W  Yuan P  Deng P  Liao F 《Journal of Zhejiang University. Science. B》2007,8(12):867-874

There was a slow-relaxing tail of skeletal muscles in vitro upon the inhibition of Ca^2＋-pump by cyclopiazonic acid （CPA）. Herein, a new linearly-combined bi-exponential model to resolve this slow-relaxing tail from the fast-relaxing phase was investigated for kinetic analysis of the isometric relaxation process of Bufo gastrocnemius in vitro, in comparison to the single exponential model and the classical bi-exponential model. During repetitive stimulations at a 2-s interval by square pulses of a 2-ms duration at 12 V direct currency （DC）, the isometric tension of Bufo gastrocnemius was recorded at 100 Hz. The relaxation curve with tensions falling from 90% of the peak to the 15th datum before next stimulation was analyzed by three exponential models using a program in MATLAB 6.5. Both the goodness of fit and the distribution of the residuals for the best fitting supported the comparable validity of this new bi-exponential model for kinetic analysis of the relaxation process of the control muscles. After CPA treatment, however, this new bi-exponential model showed an obvious statistical superiority for kinetic analysis of the muscle relaxation process, and it gave the estimated rest tension consistent to that by experimentation, whereas both the classical bi-exponential model and the single exponential model gave biased rest tensions. Moreover, after the treatment of muscles by CPA, both the single exponential model and the classical bi-exponential model yielded lowered relaxation rates, nevertheless, this new bi-exponential model had relaxation rates of negligible changes except much higher rest tensions. These results suggest that this novel linearly-combined bi-exponential model is desirable for kinetic analysis of the relaxation process of muscles with altered Ca2^＋-pumping activity.  相似文献

政府、市场与大学财政改革:台湾地区公私立大学财政改革的作为     

盖浙生  廖佩君 《北京大学教育评论》2011,9(1):107-122

本研究主要在探讨80年代至今,台湾地区高等教育财政改革所面临的问题与挑战及所采取的因应措施。台湾地区高等教育在90年代逐渐迈向普及化后,在财政困窘下,一方面是政府对大学的补助款逐年减少,一方面是大学体认到市场的优势,以市场的利基舒缓财政的压力,形成政府、市场与大学财政良性的互动关系。政府对大学财政的改革所采取的作为是:(一)以教学需求为导向,改变经费分配机制;(二)推动实施校务基金,协助公立大学财务自主;(三)对私立大学提供奖补助的经费;(四)5年500亿竞争性补助款的分配。至于市场对大学财政改革的影响,是1990年开始实施"大学弹性调整学费",除由政府订定每年收费标准外,大学按需求有10%上限的调整学费空间。对于学费征收,政府给大学自主的空间有限,学费对公私立大学有"市场失灵"的现象。所以,台湾地区公私立大学财政改革的作为仍以政府主导为主,市场的利基发挥的功能有限。最后,本文对台湾地区公私立大学未来财源筹措途径提出若干策略,作为改进的参考。  相似文献

中外图书馆出版服务研究主题比较分析     

陈春阳  廖远丽 《图书情报工作》2019,63(12):72-76

[目的/意义]图书馆出版服务受到广泛的关注且不断地发展,国内外学者纷纷开始研究其对旧图书出版服务和单一的图书馆场所服务模式的挑战及影响。通过对国内外学者研究方向和主题进行归纳总结,对比分析中外学者的关注热点,旨在引进思路并为我国图书馆出版服务提供借鉴。[方法/过程]采用LDA文档主题提取方法,并在提取出来的数据中绘制主题分布热点图。[结果/结论]通过对比国内外研究热点,发现由于国外图书馆较早开展出版服务,很多高校会根据自己的情况来制定出版服务的模式,因此国外学者的研究更多集中在分析图书馆的角色定位、线上服务、数字化趋势和战略性创新等方面;而国内学者主要是通过借鉴国外案例,并结合国内的实际情况,如经费问题、体制问题等,指出我国当前图书馆出版服务中所面临的挑战和新机遇,同时提出符合国内发展状况的模式和内外结合的创新性思路。  相似文献
