等号的历史与认知

The History and Cognition of the Equal Sign

小学生在学习中表现出对等号的认知困难,等号常被误用.在小学数学课堂教学中,追溯等号的历史,采取相应的教学策略,可以有效地促进小学生对于等号的认知.

As pupils often have difficulties in perceiving the equal sign, it is often used incorrectly by them. In mathematics teaching, by looking back to the history of the equal sign and to adopt proper teaching strategies can promote the pupils to perceive the cognition of the equal sign effectively.
