在新课标教学改革中指出操作是学生根据教师创设的问题情境与教师提供的定向指导,通过动手操作学具探究数学问题、获得数学结论、理解数学知识的一种活动。按照现代教学论的观点,数学教学不仅要使学生掌握数学知识的结论,还要让学生了解知识的发生过程,课堂教学中知识的发生过程,与人类认识过程既有联系,又有区别。学具的特点及其操作活动的特点,决定了使用学具的教学过程既不是重复人类的认识过程,又不同于直接向学生传授概念、公式和法则的传统教法。尤其是一些
In the teaching reform of the new curriculum standard, it is pointed out that the operation is a kind of activity in which the students, based on the problem situation created by the teacher and the directional guidance provided by the teacher, explore the mathematics problem through the hands-on learning device, obtain the mathematical conclusion and understand the mathematical knowledge. According to modern teaching theory, mathematics teaching should not only enable students to master the conclusion of mathematical knowledge, but also make students understand the process of knowledge, the process of knowledge in classroom teaching, both with the process of human cognition, there are differences. The characteristics of the learning tools and the characteristics of their operating activities determine that the teaching process of using the learning tools neither repeats the cognitive process of human beings nor is it different from the traditional teaching method of directly giving concepts, formulas and rules to students. Especially some
