Teacher–Student Interactions in Korean High School Science Classrooms

This paper provides a preliminary picture of teacher–student interaction in Korean senior high schools. In order to do this, the Questionnaire on Teacher Interaction (QTI) was translated into Korean and administered to 439 students (99 science-independent stream students, 195 science-oriented stream students and 145 humanities stream students). Based on the results from this survey, interviews with some students and teachers were also carried out and three science classrooms were also observed. It was found that the teacher–student interactions in Korean senior high school science classrooms reflect the general image of the youth-elder relationship in society as well as the senior high school's unique nature – portraying a scene of directing teachers and obeying students. It was also found that students experience unique interactions in their science classrooms with their particular teachers. It was considered that this difference comes from the overlapping of a teacher's personal characteristics with the nature of a stream (e.g., curriculum, expectation towards the students in that stream). This article reports part of a larger study conducted with Korean senior high school students and teachers. The aim of the main study was to investigate three different aspects of the high school science classroom environments in Korea, namely, the degree of implementation of constructivism, the pattern of teacher–student interactions, and the learning environment in laboratory classes. Based on the realisation that teacher–student interactions have not been systematically dealt with especially at the senior high school level in Korea, this article pays particularly attention to this aspect. The intention was also to provide useful insights for improving the current situation in senior high school science classrooms in Korea.     

关于声学语音学研究方法的几个问题

语音学的方法论大致体现为主观性与客观性两大类。随着语音学研究的深入发展,对声学语音学研究方法的客观性、实证性的要求也越来越高。另外,由于声学分析技术的发展和计算机的普及,对语音的物理属性的研究也越来越受到研究的关注。但是,声学语音学研究所面临的方法问题依然是深刻的。声学语音学研究的是作为语言使用的“人”发出的“音”,因此在分析资料的定夺、发音人的选定、分析条件的设定以及实验结果的考察等一系列环节中始终应该“以人为尊”、“以音为本”。     

Missing Data and Multiple Imputation in the Context of Multivariate Analysis of Variance

Multivariate analysis of variance (MANOVA) is widely used in educational research to compare means on multiple dependent variables across groups. Researchers faced with the problem of missing data often use multiple imputation of values in place of the missing observations. This study compares the performance of 2 methods for combining p values in the context of a MANOVA, with the typical default for dealing with missing data: listwise deletion. When data are missing at random, the new methods maintained the nominal Type I error rate and had power comparable to the complete data condition. When 40% of the data were missing completely at random, the Type I error rates for the new methods were inflated, but not for lower percents.     

Perceptions of Educational Studies

This paper is based on a recently completed three‐year research project undertaken with staff and students at one department of education studies in a university in England. We explored the reasons given by students for enrolling in a degree‐level programme in Educational Studies, reviewed their experiences and perceptions during their studies and made comments about career destinations. Only some of the findings that emerged from the project are reported here. Through a process of data collection undertaken in depth at one institution, and analysis in the context of literature and publicly available reports about similar work in other institutions, we illuminate some issues concerning the nature of degree programmes in Educational Studies.     

层次分析应用中的线性回归分析

国际关系研究本质上是一门科学,这就要求在变量之间建立起可供验证的理论假设以代替主观的经验猜想。层次分析方法和回归分析的结合能够较好地实现这一要求。     

教育政策研究的类别、特征和启示

教育政策研究在过去几十年中有了很大的发展,有关教育政策研究的文献非常庞杂和多样.教育政策研究可以划分为三种基本不同的研究类型,每一类研究具有相对不同的研究任务、特征和发展方向.对照这三类教育政策研究类型,可以较为清晰地看到我国现有教育政策研究的现状和不足,以及由此应该采取的发展措施.     

增强学术勇气充实专业学理

中国播音学理论研究，需要考察历史和现状，正确处理好继承与发展的关系，需要严肃认真的态度和学术勇气。播音员和主持人要“德才兼备，声形俱佳”。     

刘师培与《国粹学报》

《国粹学报》以学术为武器，“微文见志”，宣传“排满反清”，倡导学术经世，是清末民初最具影响的刊物之一。其实《国粹学报》从一开始就是学术刊物，一些学派仅仅根据其政治态度的变化而予以否定和批判，未免有失公允。作为主要办刊人和主笔者的刘师培，为该刊的创立做出了重要贡献。他在该刊上所发表的大量政论和学术文章，在当时产生了重要的影响，同时也说明了《国粹学报》在不同时期的办刊倾向，反映了清末民初中国知识分子、特别是国粹派思想变迁的过程。
