2021年4月25日周日晚，数学与统计学院20D02班于科技大楼9807开展了以“不忘初心学党史，牢记使命谱新篇”为主题的团日活动，会议由20D02班团支书范逸鹏主持，参加人员为数学与统计学院20D02班全体同学。

首先，团支书范逸鹏介绍了学习团日活动的意义，引出了中国共产党是伟大光荣正确的党，党的领导是历史的选择，人民的选择，时代的选择，党领导我们实现了民族独立、国家解放、繁荣富强的活动主题。接着团支书范逸鹏从“实现民族独立和解放、实现最广泛最深刻的社会改革、开创中国特色社会主义事业”这三个方面介绍中国共产党简史，并带领全班同学观看了中国共产党中杰出历史人物的英雄事迹。最后，团支书范逸鹏作总结发言：“坚定道路自信、理论自信、制度自信、文化自信，当代大学生应为实现中华民族伟大复兴的中国梦而奋斗。”
