核心与边缘：中学化学课堂学习者共同体特征的个案分析.doc1 核心与边缘:中学化学课堂学习者共同体特征的个案分析摘要采用文献资料法、问卷调查法、数理统计法对福州市某中学初三年级一个班级 40 位学生化学课堂学习者共同体的核心—边缘结构进行研究, 结果表明: 被试班级化学课堂学习者共同体存在显著的核心—边缘结构,较少数量的学生居于共同体的核心位置,较多学生处于边缘位置; 核心位置学生之间的共同学习密度较高, 而边缘位置学生之间的共同学习密度很小。认为: 化学教师应采取适当的教学措施, 促使更多的学生进行学习者共同体的核心位置,加强核心位置和边缘位置学生之间的知识互动。关键词核心—边缘结构学习者共同体化学课堂中图分类号: G424 文献标识码: A The Core and Edge : High School Chemistry Classroom Case Analysis ofCharacteristics of munity of Learners ZHU Yuling ( School of Education , Fujian Normal University , Fuzhou , Fujian 350007 ; Fuzhou Middle School , Fuzhou , Fujian 350009 ) Abstract Adopt document data method , questionnaire survey 2 method , mathematical statistics method of fuzhou middle school third grade ina class of 40 students in chemistry classroom students core edge structures are studied , the results showed that the participants class plays a significant role in chemistry classroom munity at the heart of the edge structure and less number of students in munity at the heart of the position , more students in the edge position ; Core position students' between mutual learning density is higher , and the edge position between students study together density is small that chemistry teachers should take proper teaching measures to encourage more students to the core of munity of learners , to strengthen the core position and the edge position the knowledge interaction between the students.
