摘　　要：以当前高职商务英语实践教学中人才与实际需求无法对接、培养目标模糊、校企合作不够深以及教学制度不规范等问题为着眼点,设计了一种以改进ID3决策树为基础的高职商务英语时间教学成效评价模型,并以ID3决策树算法为基础,优化了数据集的属性选择和信息增益。站门的仿真实验结果表明,本文设计的改进算法在很大程度上降低了元算法的运算开销。之后又借助改进模型对某高职院校进行了评定,以实例评定结果为依据进行了改进策略的设计,包括实践教学目标体系、实践教学内容体系、实践教学管理和评价体系等等。Current business English practice teaching exists many problems, such as the disconnection between talents and company requirement, fuzzy talents training aim, weak cooperation between schools and companies and less standard forms of teaching system. In view of these situations, this paper put forward a business English practice teaching evaluation model based on improved ID3 decision-making tree. On the basis of ID3 decision-making tree, the attribute selection and information gain of the data set is optimized. The simulation experiments show that the improved algorithm greatly reduces the operation cost. Then this improved model is applied in a vocational college for the example evaluation. Finally, according to the case evaluation results, corresponding improvement methods are proposed about objective system, content system, management and evaluation system and security system in vocational college business English practice teaching.
