近几年有机会给哈工大自然辩证法研究生、自然辩证法专业班、黑龙江大学数学和物理研究生、哈师大数学系本科高年级等几个单位讲过有关数学史、数学方法论和数学哲学课程。由于对象不同,时间多少也不同(少者十几个学时,多者二、三十个学时,或五、六十个学时),当然所讲内容、讲授方法也有所差 In recent years, he has been able to lecture on the history of mathematics, mathematics methodology, and philosophy of mathematics for graduate students in the dialectical nature of Harbin Institute of Technology, natural dialectics professional classes, graduate students of mathematics and physics of Heilongjiang University, and senior students of mathematics department of Harbin Normal University. Because of different subjects, the time is somewhat different (more than a dozen students learn more hours, more than two or thirty learners, or five or sixties, etc.). Of course, the contents and teaching methods are also different.
