摘要/Abstract

摘要： 由于线上教学的教学效果受教学手段和内容的局限性, 导致体育线上教学效果评价的准确性较低, 为此, 基于模糊K均值聚类算法设计了多指标的评价方法。首先构建体育线上教学效果多指标评价模型, 划分影响体育线上教学质量的关键元素, 求解指标权重, 采用模糊K均值聚类法将体育线上教学效果评价指标参数进行聚类与合并, 使具有非线性时间序列特性的教学能力收敛指标参变量约束处理后, 得到定量递归结果, 从而避免教学环境的干扰, 完成高精度体育线上教学效果评价。实验结果表明, 所提方法评价可以在保证体育线上教学效果高精度评价的基础上, 提高运算速率。

Abstract: Because the teaching effect of online teaching is influenced by teaching means and teaching content, the accuracy of online teaching effect evaluation of physical education is low. Therefore, a multi-index evaluation method based on fuzzy K-means clustering algorithm is designed. Firstly, the multi-index evaluation model of online sports teaching effect is constructed, the key elements that affect online sports teaching quality are divided, the index weights are solved, and the evaluation index parameters of online sports teaching effect are clustered and merged by fuzzy K-means clustering method, so that the quantitative recursive results can be obtained after the parameters of convergence index with nonlinear time series characteristics are constrained, avoiding the interference of teaching environment and completing the high-precision online sports teaching effect evaluation. The experimental results show that the proposed evaluation method can improve the operation speed on the basis of ensuring the high-precision evaluation of online teaching effect of physical education.
