摘　　要：传统的高校公共体育实践课教学模式、教学方法是学生以基本技术、基本战术等为主要内容的技术教学、技能培养。注重教学形式、结构、内容、方法、考核、评价等的统一性与标准化。在当前国家体育赋予高校体育新目标与要求的情况下,旧的教学模式和方法的局限性和片面性便显现出来。采用文献资料法、调查访问法、问卷调查法、数理统计法等综合研究方法,以西安市11所高校中的400名学生为调研对象,利用决策树算法从整体的、系统的与发展的角度对高校公共体育课实践教学影响因素进行较全面而深入的研究,研究结果表明"学生参赛次数"是决策分支最重要的影响因素,其次"喜好程度"以及"教师技术等级"也是影响高校公共体育实践教学的重要方面。Basic technical teaching like technique and tactical skill training constitutes traditional college P.E. main stream. They are regarded as teaching model and teaching method from early days onward. These traditional methods lay focus on form, structure, contents, teaching methods, uniformity and standardization of assessment, evaluation, etc. Against the sce nario, in which colleges were endorsed with new standard form National Education Dept. , those outdated mode of teaching find itself hardly adaptable as they are either too narrow -minded or much one -sided. This article, based on literature con sultation, and investigation access method, and questionnaire survey, and statistics analysis, put 400 students from 11 universities into re＇search. With the help of Decision Tree Algorithm, the factors which influence the college P. E. classes were systematically analyses. The results show that ＂the number of students participating,＂ as decision -making branch is the most important factor followed by the factors of ＂preference＂ and ＂technical grade. The two also affect the practice of physical education profoundly.
