【摘要】 规范地进行实验数据记录和处理是每个理工科工作者必备的科学素养和基本技能。能否掌握此技能很大程度上取决于对有效数字概念的理解和运算规则的正确运用。大学阶段是系统学习有效数字的最后阶段,但往往出现知识虽简单易懂,掌握却成为难点的现象。分析发现,教师对相关教学内容的重视程度、理论与实践联系的紧密程度、课程间要求的统一性不够是此现象形成的主要原因。针对这几个原因,制定了强化有效数字教学的各项改革措施,经过四年的实践,成效较为显著。更多还原

【Abstract】 Proper data recording and processing are essential scientific knowledge and skills,which to a large extent depend on the understanding of the rules of signifcant figures and correct use of rules of calculation. The unversity period may be the last step of systematic learning of significant figures for students,but often a phenomenon appears that simple knowledge becomes difficulty to grasp. The reason of this phenomenon is probably a combination of inadequate attention being paid,less correlation of theory to practice and different requirements of different courses. With these in minds we put forward our own reformation measures to strength the teaching on significant figures and have obtained good results on this issure after 4 years of practice.更多还原
