在初中一年级数学课上最先碰到的一个问题是帮助学生对“0”的再认识。这是由于负数的引入,使“0”的地位发生了变化。它已不仅表示“没有”,而还有着丰富的意义。下面谈谈个人对这段教学的粗浅见解,和大家共同探讨。 1.要使学生认识到“0”也是一个数。在小学阶段,学生对“0”的认识,往往把它理解为“没有”。直到初中一年级引入负数以后, One of the first problems encountered in mathematics classes in the first grade of junior high school is to help students re-understand the “0”. This is due to the introduction of negative numbers, which changed the status of “0”. It has not only expressed “nothing” but also has rich meaning.
