Study on the reciprocating record method

  • Online:2012-10-25 Published:2012-10-20

摘要: 大学物理的几个实验中都采用了“往返读数法”,但大多数教材对为什么这样做并未作出解释,或只含糊说明,甚至在不该采用该法的个别实验中堂而皇之地使用着,以致该法在实际教学中难免产生一些疑问,不利于学生科学精神的培养,本文对此问题进行了探究。

关键词: 往返读数法, 理由, 必要性

Abstract: While the reciprocating record method is used in some college physics experiments, most of the textbooks do not explain why use it or give vague explalation. Some even use this method in a few experiments which should not use it. This may arise some problems in practical teaching and is unfavorable to cultivating students' scientific spirit. The paper studies on this problem.

Key words: reciprocating record method, reason, necessity
