论艺术教育中的美感成长与爱的教育     

施荣华 《云南师范大学学报(哲学社会科学版)》2006,38(6):96-101

当代的艺术教育，必须始终以受教者的美感成长和爱的教育为根本内容。在美感体验中，艺术作品一旦进入个体的审美视角，作品所表达的情感便被激活，成了与欣赏者对话、交流的对象，并向欣赏者展示其生命运动的深层价值。爱的教育实质上就是情感教育。这种情感教育在艺术教育中显得尤其鲜明强烈和独特有效。  相似文献   

1957年后公民权利受挫的宪政思考     

王宝治  许振台 《河北师范大学学报(哲学社会科学版)》2005,28(4):48-53

五四宪法的颁布为新中国公民权利理论与实践的发展提供了强大的法律基础。新中国公民权利理论与实践的开局是好的。但是，从1957年夏起，新中国的法制建设却急转直下，而到了文化大革命，公民权利的破坏更是到了令人发指的地步。公民权利之所以在1957年以后受到严重的挫折，并不是偶然的。这与当时的社会历史状况有着密切的联系，究其原因主要在于三点：即人治思想的泛滥，高度集中的计划经济体制，以及淡薄的法律意识。  相似文献   

建筑风景画的美学品格与文法范式     

雍建华 《重庆第二师范学院学报》2005,18(2):39-41

建筑风景绘画样式除了各种表现策略外,还有自身的文法范式及构成它自身的表意元素.学习和掌握建筑风景画,有利于提高建筑表现图画的专业表达能力;通过准确反映甚至强化建筑设计意图,增强对建筑、自然的了解,可为建筑设计积累专业素材和专业养分.在绘画表现中,真正掌握建筑风景画的文法范式,对提高建筑风景的审美品格与价值有着十分重要的现实意义.  相似文献   

文学性的迷失与廓清     

罗宏 《河南师范大学学报(哲学社会科学版)》2005,32(3):110-113

当前中国文学理论界面临文学性迷失问题。这将使文学独立存在的合法性面临逻辑的解构。文学性迷失的实质是一种价值迷失。因此，纠正价值偏见、兼顾文学的关系属性考察与固有属性考察、强化文学性的共时普遍性与特质性等等是文学理论研究所必须进行的学术清理。  相似文献

Mathematical Modeling in the Primary School: Children's Construction of a Consumer Guide     

Lyn D. English 《Educational Studies in Mathematics》2006,63(3):303-323

This paper examines 6th grade children's local conceptual development and mathematization processes as they worked a comprehensive mathematical modeling problem (creating a consumer guide for deciding the best snack chip) over several class periods. The children and their teachers were participating in a 3-year longitudinal teaching experiment in which sequences of mathematical modeling problems were implemented from the 5th grade (10 years of age) though to the 7th grade. In contrast to traditional problem solving, mathematical modeling requires children to generate and develop their own mathematical ideas and processes, and to form systems of relationships that are generalizable and reusable. Reported here is a detailed analysis of the iterative cycles of development of one group of children as they worked the problem, followed by a summary of the mathematization processes displayed by all groups. Children's critical reflections on their models are also reported. The results show how children can independently develop constructs and processes through meaningful problem solving. Children's development included creating systems for operationally defining constructs; selecting, categorizing, and ranking factors; quantifying quantitative and qualitative data; and transforming quantities.  相似文献   

Tracking Pre-service Teachers’ Changing Conceptions of Good Science Teaching: The Role of Progressive Reflection with the Same Video     

Benny Hin Wai Yung  Siu Ling Wong  Man Wai Cheng  Ching Sum Hui  Derek Hodson 《Research in Science Education》2007,37(3):239-259

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit, develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on their changing conceptions of good science teaching. PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree.  相似文献
