基于聚类分析的初三化学学业质量发展研究

Study on Chemistry Academic Quality Development of Junior High School Based on Cluster Analysis

以2013-2016年广州市各区(县级市)中考化学成绩的4种数据为指标,运用聚类分析研究广州市区域初三化学学业质量的发展状况。研究发现各区(县级市)主要分为3大类,部分区在不同年份的类别中移动,倾向于建立一个包括越来越多区域的第1大类。广州市区域初三化学学业质量逐步向优质均衡发展。系统的中学生化学探究活动和化学教师研训活动是实现这一发展的重要原因。

Based on the 4 kinds of data of senior high school entrance examinatlon scores m Guangzhou districts (county-level cities)from 2013 to 2016,this paper used cluster analysis to analyze the status of regional chemistry academic quality development of junior high school.This research showed that three categories were classified.Some districts moved in the results of cluster analysis in different years,and tended to merge into the first category including more and more districts.Guangzhou junior high school students' chemistry academic quality was achieving high quality and balanced development.Systematic research and training adtivities for chemistry teachers and scientific inquiry activities for students in junior high school were important reasons for this development.
