在评定学生学业成绩和评价学校教学质量时,通常选用学生语、数、外三门学科统考成绩作为代表学生的学业综合成绩,但从未见到其合理性的检验报告.本文运用R聚类分析法,对来自我市×区两所市属重点中学,经随机抽样的622名高中学生的政治、语文、数学、外语、物理、化学6门学科,85年的全区统一考试成绩进行处理,检验,以语、数、外三门学科统考成绩,代表学生学业综合成绩,评价学生学习质量和评价学校教学质量的合理与否.现将结果报告如下:一、资料采集:鉴于重点中学学生对各学科的学习发展较为均衡,较少存在学习上的偏废现象,为此在×区两所市属重点中学内随机整班抽样,收集高一211名、高二266名、高三188名学生的85年全区统一考试的上述6门学科的统考成绩为本次分析材料,以保征R聚类分析结果具有相对较高的可
When assessing students’ academic performance and evaluating school teaching quality, students’ language, number, and three subjects are generally used to represent the student’s comprehensive academic achievement. However, their rationality test report has never been seen. This paper uses R clustering. The analysis method deals with 6 disciplines of politics, language, mathematics, foreign language, physics, and chemistry of 622 high school students randomly sampled from the two key city middle schools in our city*s district, and 85 years of unified scores in the district. The results of the examination, the results of the three subjects, the scores of foreign language, mathematics, and mathematics represent the students’ academic performance, evaluate the quality of student learning, and evaluate the quality of school teaching. The results are reported as follows: 1. Data collection: Given the importance of secondary school students The learning development of various disciplines is relatively balanced, and there is less partial neglect in learning. For this reason, random samples are collected from two key high schools in District X, and 211, 266, and 188 high-school students are collected. The examination results of the above six disciplines for the 85 district-wide unified examinations are based on this analysis. The results of the R cluster analysis are relatively high.
