动手操作是学生学习数学的重要方式,也是有助于课改下的“以生为本”理念贯彻落实的有效方式之一。但是,在应试教育下,我们对学生总是存在一定的不放心,致使学生很少有机会进行自主学习,导致学生的依赖性较强,自主力较差,严重不利于学生数学素养的培养。所以,在课程改革下,教师要认真贯彻落实以学生的发展为中心的教学理念,并 Hands-on operation is an important way for students to learn mathematics and is also one of the effective ways to implement the concept of “students-oriented” under the guidance of curriculum reform. However, under the exam-oriented education, we always feel uncomfortable about students, resulting in few opportunities for students to carry out autonomous learning, resulting in a strong dependence on students with less autonomy, which is seriously detrimental to the cultivation of students’ mathematical qualifications. Therefore, under the curriculum reform, teachers should conscientiously implement the teaching philosophy centered on the development of students and
