摘　　要：为了提高英语教学质量评估的有效性,采用决策树建立教学质量评估指标分类规则,同时采用关联规则分析对评估结果进行验证.提取英语教学质量评估的有效指标,对指标属性进行量化和泛化处理;根据待评估样本计算各指标属性的熵增益并对熵增益率降序排序,分别获得根节点和分支节点,结合节点属性值得到分支个数,构建完整的教学质量评估决策树;采用关联规则分析方法求解各指标属性的支持度和置信度,根据关联分析结果验证决策树评估的有效性.结果表明,科学设置评估指标参数,并合理选择评估指标属性分段区间.通过本文方法可以较好地评估分析影响英语教学质量关键要素及内在联系.In order to improve the effectiveness of English teaching quality evaluation,decision tree was used to establish the classification rules of teaching quality evaluation indicators,and association rule analysis was used to verify the evaluation results.Firstly,the effective indicators of English teaching quality evaluation were extracted,and the attributes of the indicators were quantified and generalized;then the entropy gain of each indicator attribute was calculated according to the samples to be evaluated,and the entropy gain rate was sorted in descending order to obtain the root node and branch node respectively,and the number of branches was obtained combined with the attribute value of the node,and then a complete decision tree of teaching quality evaluation was constructed;finally,the association rules were used Then the support and confidence of each attribute were calculated by the analysis method,and the effectiveness of the decision tree evaluation was verified according to the results of association analysis.Experiments showed that the key factors and internal relations that affect the quality of English teaching can be better evaluated and analyzed by setting the evaluation index parameters scientifically and selecting the evaluation index attribute segmentation interval reasonably.
