“简笔”的意蕴与审美趣味——论教学简笔画艺术语言与艺术表达形式

＂简笔＂所包含的意蕴是教学简笔画艺术语言与艺术表达形式的核心。＂简笔＂的意蕴具体而充分地实现,不仅在于教学简笔画所运用的线条语言形式以及所强调的简洁、生动、流畅的用笔,而且其所采用的程式化艺术表达形式实质上就是符号化艺术表达形式的进一步升华。从某种意义上来说,它们两者之间实现了一减再减的递进关系,从而进一步增强了＂简笔＂的意蕴和审美趣味。

内疚的界定和测量以及研究方法述评

作为人类高度社会化的负性自我道德情感体验,内疚是个体对自身经历的不良事件进行评价和认知的产物,同时也是影响个体后续行为的重要因素,它与个体的身心健康和社会化的发展有着非常密切的关系。西方心理学界对这一情绪进行了大量的研究。国内关于内疚的研究报告零星可数。对内疚的概念界定与测量、内疚态度的研究现状进行系统的阐述,有助于深入探讨内疚领域特有的问题。     

Using students’ feedback for teacher education: measurement invariance across pre-service teacher-rated and student-rated aspects of quality of teaching

Comparing self-perceived quality of teaching to students’ perception can be used in higher education to improve the quality of teaching of pre-service teachers in teacher education. However, comparing these measurements from different perspectives is only meaningful if the same constructs are being measured. To shed light on this comparison’s meaningfulness, we scrutinised whether aspects of quality of teaching are measured in the same way across pre-service teachers and their students by means of measurement invariance analyses. To do so, 272 pre-service teachers in teacher education rated aspects of their quality of teaching, and were rated by their 4851 students. Measurement invariance across these perspectives was tested in multilevel structural equation models. Strong measurement invariance held for two aspects of quality of teaching; for the third, one item lacked weak measurement invariance. Pre-service teachers perceived their quality of teaching lower than their students. In conclusion, aspects of quality of teaching can be compared across perspectives, and teacher education should encourage pre-service teachers to use students’ feedback as a valuable resource for improving their quality of teaching.     

试析东观主人评点《红楼梦》之“补笔”与“特写”论

在对《红楼梦》人物塑造的阐释中,东观主人较早地提出了＂补笔＂和＂特写＂两种方法。认为人物描写离不开＂补笔＂,适当的＂补笔＂有利于刻画人物性格;而且为了突出某个人物,有时需要着意描写——＂特写＂。这既丰富了《红楼梦》评点之人物论,也发展了明末清初以来关于人物塑造的理论认识。
