Introduction:

段老师毕业于内蒙古科技大学，曾长期就职于上海证券交易所，为软件工程师，专事Oracle 数据库管理员，数据库开发，项目管理多年。
十年前移居美国后开始关注数学教育，发现许多学校数学教育重方法重技巧，轻概念理解，轻抽象逻辑培养。在对算数，代数，几何，数论，统计，微积分系列辅导过程中发现学生是否在小学阶段培养起良好的抽象逻辑思维对后续数学学习至关重要，因此投身于小学数学教育，期待为学生打下坚实的基础。
Mrs. Duan has been a software engineer, specializing in Oracle database administrator, database development and project management for many years.
After emigrating to the United States ten years ago, She began to pay attention to mathematics education. It was found that mathematics education in many schools focuses more on procedures and tricks, much less on conceptual understanding and abstract logic training. In the process of teaching arithmetic, algebra, geometry, number theory, statistics and calculus, she realized that whether students cultivate good abstract logical thinking in primary school is very important for subsequent mathematical learning. Therefore, she devotes herself to primary school mathematics education and looks forward to laying a solid foundation for students.
