Monitoring and guiding instructional management require student performance evaluation. Traditional evaluation and analysis methods based on absolute scores, on the other hand, have certain flaws and are unable to fully reflect the information contained in student performance, thus limiting the impact of student performance evaluation on teaching and learning management. Data mining is regarded as the backbone technology for future information processing, and it introduces a new concept to the way humans use data. Schools must analyse and evaluate the performance of students in the same grade level and secondary school in a timely and staged manner. Clustering is a type of data mining that uses similarity rules to classify sample data into groups with a high degree of similarity. To address the difficulties caused by the wide variation in course difficulty in student performance evaluation, a method based on the -means clustering algorithm is proposed. The -means algorithm and the improved K-means algorithm with student information are investigated. The test results showed that the -means clustering algorithm, the improved algorithm in this paper, and the fast global mean clustering algorithm all cluster the same randomly generated data set with noisy points, but the clustering time of the algorithm in this paper is only 0.04, which has obvious advantages. As a result, the clustering algorithm-based higher education management and student performance evaluation mechanism provides some insights for future research on student learning patterns. It is hoped that instructional administrators will gain a better understanding of students' learning characteristics so that they can better guide their teaching.
监测和指导教学管理需要学生表现评估。然而,基于绝对分数的传统评估和分析方法存在一定的缺陷,无法充分反映学生表现所包含的信息,从而限制了学生表现评估对教学管理的影响。数据挖掘被视为未来信息处理的骨干技术,它为人类使用数据带来了新的概念。学校必须及时分阶段地分析和评估同一年级和中学学生的表现。聚类是一种使用相似性规则将样本数据分类为高度相似的组的数据分析方法。针对学生表现评估中课程难度差异较大的问题,提出了一种基于 -means 聚类算法的方法。研究了 -means 算法和基于学生信息的改进 K-means 算法。测试结果表明, -means 聚类算法、本文提出的改进算法和快速全局均值聚类算法都对具有噪声点的随机生成数据集进行了聚类,但本文算法的聚类时间仅为 0.04,具有明显的优势。因此,基于聚类算法的高等教育管理和学生表现评估机制为未来研究学生学习模式提供了一些思路。希望教学管理人员能更好地了解学生的学习特点,从而更好地指导教学。
