浅谈美术教学中学生创造性思维的培养     

赖英 《基础教育研究》2011,(6):49-50

“美术”这个词,人们通常注意“美”而不注意这个“术”字。所谓“术”,通俗地说是指技能性活动,但它是一种服务于生活、服务于人类对美的追求的活动;与此同时,它还是指创造性思维与激情相碰撞之后所产生的一种艺术作品。好的美术作品离不开创造性思维。什么是创造性思维呢？是指人们在已有经验的基础上,发现新事物,创造解决问题的新方法的高级思维过程。  相似文献

关于地方本科院校质量提升的探讨     

来俊军 《河南科技学院学报》2013,(12):10-13

地方本科院校占全国普通本科院校的八成以上,其办学质量如何,对提高高等教育质量、建设高等教育强国至关重要。当前,影响地方本科院校办学质量的主要问题有：教学和科研发展不均衡,导致教学弱化、学术异化;人才培养中心地位不到位,“以学生为中心”的理念和实践亟需加强;大学内部治理中,教授治学、民主管理的理念尚未有效落实;高校管理的专业化水平不高,需要进一步更新观念,提高执行力和创新力;高校“去行政化”的核心在于行政权力和学术权力各得其所,这需要制度建设和大学文化的有力支撑。只有切实解决以上问题,地方本科院校才能提高办学质量,实现科学发展。  相似文献   

Bayesian Inference and Application of Robust Growth Curve Models Using Student's t Distribution     

Zhiyong Zhang  Keke Lai  Zhenqiu Lu  Xin Tong 《Structural equation modeling》2013,20(1):47-78

Despite the widespread popularity of growth curve analysis, few studies have investigated robust growth curve models. In this article, the t distribution is applied to model heavy-tailed data and contaminated normal data with outliers for growth curve analysis. The derived robust growth curve models are estimated through Bayesian methods utilizing data augmentation and Gibbs sampling algorithms. The analysis of mathematical development data shows that the robust latent basis growth curve model better describes the mathematical growth trajectory than the corresponding normal growth curve model and can reveal the individual differences in mathematical development. Simulation studies further confirm that the robust growth curve models significantly outperform the normal growth curve models for both heavy-tailed t data and normal data with outliers but lose only slight efficiency for normal data. It appears convincing to replace the normal distribution with the t distribution for growth curve analysis. Three information criteria are evaluated for model selection. Online software is also provided for conducting robust analysis discussed in this study.  相似文献   

A Modified Comparative Fit Index for Factorial Invariance Studies     

Mark H. C. Lai  Myeongsun Yoon 《Structural equation modeling》2013,20(2):236-248

As a prerequisite for meaningful comparison of latent variables across multiple populations, measurement invariance or specifically factorial invariance has often been evaluated in social science research. Alongside with the changes in the model chi-square values, the comparative fit index (CFI; Bentler, 1990) is a widely used fit index for evaluating different stages of factorial invariance, including metric invariance (equal factor loadings), scalar invariance (equal intercepts), and strict invariance (equal unique factor variances). Although previous literature generally showed that the CFI performed well for single-group structural equation modeling analyses, its applicability to multiple group analyses such as factorial invariance studies has not been examined. In this study we argue that the commonly used default baseline model for the CFI might not be suitable for factorial invariance studies because (a) it is not nested within the scalar invariance model, and thus (b) the resulting CFI values might not be sensitive to the group differences in the measurement model. We therefore proposed a modified version of the CFI with an alternative (and less restrictive) baseline model that allows observed variables to be correlated. Monte Carlo simulation studies were conducted to evaluate the utility of this modified CFI across various conditions including varying degree of noninvariance and different factorial invariance models. Results showed that the modified CFI outperformed both the conventional CFI and the ΔCFI (Cheung & Rensvold, 2002) in terms of sensitivity to small and medium noninvariance.  相似文献   

The effect of hands-on ‘energy-saving house’ learning activities on elementary school students’ knowledge,attitudes, and behavior regarding energy saving and carbon-emissions reduction     

Lung-Sheng Lee  Yunn-Horng Guu  Liang-Te Chang  Chih-Chien Lai 《Environmental Education Research》2013,19(5):620-638

Energy saving and carbon-emissions reduction (ESCER) are widely regarded as important issues for progress towards ensuring sustainable forms of economic development. This Taiwanese study focuses on the effects of a series of educational activities about ESCER on students’ knowledge, attitudes and behavior. Sixty fifth-grade students from two elementary school classes were assigned to an experimental group, and 59 from two others to the control. Covariance and qualitative data analysis were conducted after 14 lessons on the topic in both ‘treatments.’ The following key findings emerged. First, hands-on ‘energy-saving house’ learning activities seemed to have positive effects on students’ knowledge, attitudes, and behavior toward ESCER, even as the design of authentic learning activities was recognized as not being as closely aligned to the students’ daily lives as they could have been for achieving behavior-related outcomes. Second, students demonstrated slight gains in conceptual knowledge and procedural knowledge via the hands-on activities, but some ESCER misconceptions persisted. We conclude that students’ learning processes, prior learning and authentic contexts for ESCER-related work should not be ignored in the attempt to link knowledge to action in teaching and learning activities.  相似文献   

The impact of reform policies on teachers' work and professionalism in the Chinese Mainland     

Leslie Nai-Kwai Lo  Manhong Lai  Lijia Wang 《Asia-Pacific Journal of Teacher Education》2013,41(3):239-252

This paper examines the impact of reform policies on the work of Chinese teachers. It explores the policy context in which a fragile teaching profession attempts to develop and discusses the dynamics of interacting societal forces that have created the dilemmas for the teachers. The authors argue that while the continual implementation of reform policies has fostered a new outlook in Chinese schools, calls for profound change in schooling have caused much anxiety among teachers. The teachers' anxiety stems from the incongruence between their professional outlook, which is intimately linked to student academic achievement, and the dictates of state reform measures, which seek to broaden the conception of education to include other areas of human development. Throughout the years of reform, teachers have had to stretch their professional capacity in order to satisfy competing demands engendered by reform measures and educational reality. It is in the tensions caused by the implementation of reform policies that the humanism of teacher professionalism is magnified. In this paper, the authors discuss the educational and social issues that surround the teachers' preference for conventional practices.  相似文献   

Implementing a new senior secondary curriculum in Hong Kong: instructional leadership practices and qualities of school principals     

Edith Lai  Derek Cheung 《School Leadership & Management》2013,33(4):322-353

This paper attempts to identify the leadership practices and qualities of school principals engaged in implementing a curriculum reform in Hong Kong. Based on interview data of school principals, this paper shows that the types of instructional leadership practices that school principals adopt and the contextual conditions in which these practices occur are key factors explaining the differential effectiveness of implementation efforts. Six efficacious instructional leadership practices and two contextual conditions critical to their development were identified. This paper reconceptualises instructional leadership as a collective and transformational endeavour, functioning in communities of practice to support school development at different levels.  相似文献
