学生自主学习能力培养中师生自主性的再认识     

彭飞霞  吴南中 《湖南广播电视大学学报》2011,(4):5-9

自主学习能力的提高已成为绝大多数学生的迫切需要,这个过程需要教师的积极参与。学生自主在很大程度上取决于教师自主,自主学习能力的培养首先要关注教师的自主性,具体体现在观念和实践两个层面。学习建构的主体在于学习者自身,所以自主学习能力的培养也要关注学生自身的自主性。而要真正提高学生的自主学习能力,从师生自主性的任一方面来施...  相似文献

Teaching styles and conceptions of effective teachers: Tibetan and Han Chinese academics compared     

Li-fang Zhang 《Learning and individual differences》2011,21(5):619-623

The principal objective of this research is to ascertain if the “research–teaching dichotomy” as revealed in the relationship between conceptions of effective teachers and teaching styles among Han Chinese academics can be found among Tibetan academics. As a preliminary objective, this research examines the appropriateness of the Effective Teacher Inventory (Zhang, 2003) for evaluating Tibetan academics' conceptions of effective teachers and compares the conceptions of effective teachers between Tibetan and Han Chinese academics. The Thinking Styles in Teaching Inventory (Grigorenko & Sternberg, 1993) and the Effective Teacher Inventory (Zhang, 2003) were administered to 162 Tibetan academics. For the purpose of comparison, data from 93 Han Chinese academics in Zhang's (2009) study were integrated into the present research.The results warranted two conclusions. First, the Effective Teacher Inventory was appropriate for assessing Tibetan academics' conceptions of effective teachers; and there was no substantial difference in the conceptions of effective teachers between the two samples. Second, as it was among Han Chinese academics, the apparent “research–teaching dichotomy” was identified among Tibetan academics. Limitations and significance of this research are discussed and directions for future research are proposed.  相似文献   

Teaching about the importance of trees: a study with young children     

Yannis Hadzigeorgiou  Barbara Prevezanou  Mary Kabouropoulou  Manos Konsolas 《Environmental Education Research》2011,17(4):519-536

This paper reports on a study undertaken with the primary aim of investigating the effect of the storytelling teaching approach on kindergarten children's retention of ideas about the importance of trees. The study also assessed the effect of storytelling on children's intention to participate in a tree planting activity that they had to select from a list of activities. The story that was created included such elements as binary opposites, mental images, mystery, and wonder, according to Kieran Egan's theory. The study utilized a two‐group design, was conducted in three phases (pre‐test, intervention, and post‐test), lasted 11 weeks, and its results provide evidence of the effectiveness of the storytelling approach when compared with the traditional method of expository teaching complemented with visual images (pictures) of trees and their importance to human beings. The pedagogical appropriateness of the story, which was based upon the binary pair of opposites ‘security–insecurity’, is also discussed in the paper.  相似文献
