同事聊过这样的事例,老师问学生这样一个问题:“你有5元钱,现在买笔和本花去了一元钱,你还剩几元钱?”学生都能不假思索地答出还剩四元钱。但如果让学生据此列出算式并作答,结果就不那么令人欣慰了。总有几个学生不知所措,老师也为此苦恼不已。如果当作个题而议论学生的数学水平,甚至逻辑能力,未免有些武断。这种现象并非偶然,有着更深层次的原因。从这件事上,体现出学生思维的发展规律,从教育层面讲,有着新旧两种教育理念的差异。 Colleagues talked about such an example, the teacher asked the students such a question: “You have 5 dollars, now buy pen and flower spent a dollar, you have a few dollars left?” Students can answer without hesitation Left four dollars. But if you ask students to formulate the answer and answer it, the result is less encouraging. There are always a few students overwhelmed, teachers are distressed. If as a subject to talk about the mathematical level of students, or even logical ability, it is somewhat arbitrary. This phenomenon is not accidental, with a deeper reason. From this incident, it reflects the law of development of student thinking, from an educational level, there are differences between the two old and new educational concepts.
