Explaining discrepancies between teacher beliefs and teacher interventions in a problem-based learning environment: A mixed methods study

The purpose of this study was to explore the discrepancy between teacher beliefs and behavior in a Problem-Based Learning (PBL) environment. Using a survey and observations, this study demonstrated that tutors prefer learner-oriented beliefs, but in their teacher behavior they showed a more traditional approach to teaching. Analysis of semi-structured interviews indicated that this inconsistency could be attributed to the way in which problem-based learning is embedded in the curriculum, the confidence teachers have in the self-directed capabilities of students, and the self-confidence of teachers regarding their own facilitation skills.     

全面、科学的汉字构造理论应当是“四书”说——兼论“六书”说到“三书”说的发展及其比较

介绍了六书到三书的发展,并比较了六书和三书的异同以及现代学者三书说之间的优长,认为在归纳汉字结构方面,无论是传统的六书还是现代的三书,都有偏颇之处,都不能涵盖古今所有汉字的结构类型。分析了古今汉字的结构类型,用大量的字例证明,汉字的结构原理应该是四书,即表意字、形声字、假借字和记号字。
