等号可能是学校数学中最常见的符号，对它的理解通常被认为在数学上是简单的。事实上，在学生早期小学教育期间首次引入这一概念后，在高年级时，很少（如果有的话）明确地花在这个概念上的教学时间。然而研究表明，所有年级的许多学生都没有充分理解等号的含义（Baroody 和 Ginsburg 1983；Behr、Erlwanger 和 Nichols 1980；Falkner、Levi 和 Carpenter 1999；Kieran 1981；Knuth 等 2006）。例如 Eric J.

tThe equal sign is perhaps the most prevalent symbol in school mathematics, and developing an understanding of it has typically been considered mathematically straightforward. In fact, after its initial introduction during students’ early elementary school education, little, if any, instructional time is explicitly spent on the concept in the later grades. Yet research suggests that many students at all grade levels have not developed adequate understandings of the meaning of the equal sign (Baroody and Ginsburg 1983; Behr, Erlwanger, and Nichols 1980; Falkner, Levi, and Carpenter 1999; Kieran 1981; Knuth et al. 2006).
