摘要： 生物统计学是生物学类和农学类本科专业的重要基础课，随着理论课学时数的减少，必须增设相应的实验课，以强化教学效果。实验课既要传授SAS编程的基本知识，又要与统计方法相结合，解决科研应用问题。教学面临学时数少、内容多等问题。采用比较教学法，运用实际教学案例，通过数据表格与SAS数据集比较、理论公式计算与SAS软件运算比较、同一SAS程序不同参数比较、相似SAS程序不同运算结果比较及一题多解等办法，增强了学习生物统计学的兴趣，取得了良好的教学效果。

Abstract: Biostatistics is an important and basic course for undergraduate students specializing in life science and agronomy. With the decreasing number of theoretical class hours, the corresponding experimental course must be added to intensify biostatistical teaching. Biostatistical experiment course needs to teach the basics of SAS programming with a combination of statistical methods to solve practical problems in scientific research and application. The issues confronting biostatistical experiment course are less number of teaching hours, along with more content. In this article, the application of comparative method in teaching biological experiment was discussed and the actual teaching cases were designed. These include the comparison of different formats of data table and SAS data set, the calculation results obtained from theory formula and SAS software, different parameters from the same SAS program, various results using similar SAS programs and multiple solutions to one problem. The results showed that comparative analysis can be used for teaching biostatistical experiment with promising teaching effects and enhancing the student′s interest.
