高频词与低频词的界分及词频估算法

Mr. J.C. Donohue, in 1973, believe that there was a critical value in the demarcation of high-and low-frequency terms used in articles, and at the same time he proposed formulas of calculation. On the basis of adopting maximum value to determine grades of terms, this article brings forth and introduces a new formula of demarcating the high-and low-frequency terms which is not only simple and direct in the process of calculation but also more practical as compared with that of Mr. Donohue. Having made a study of ways of calculating for various kinds of terms with similar frequency,the article also gives a formula of calculation and reveals the inheret law governing the number of frequency of terms ans terms with similar frequency.The author holds that the frequency of terms appeared in the article and the number of terms with similar frequency have something to do with the number of different terms but have nothing to do with the length of the articles.10 formulas.5 tables.4 references.     

研究性阅读教学模式的实践与思考

“学习的革命”曾一度风靡全球，20世纪90年代以来，世界各国都把学习方式的转变视为课程改革的重要内容，欧美请国纷纷倡导“主题探究”与“设计学习”，“综合学习时间”的设置被认为是日本即将推行的新课程最突出的特色之一，中国国家教育部2000年1月颁布了《全日制普通高级中学课程计划（试验修订稿）》，该计划规定研究性学习课程为必修课。现结合自己的教学实践。谈谈阅读教学如何实施研究性学习的问题。
