认真研读、挖掘教材是上课的前提和需要。我们目前使用的教材,以新课程标准为依据,更加关注数学与生活实际的密切联系,加强了探究学习和动手实践学习方式的运用,为学生思维的发展提供了广阔的空间,但教材是静态的,其中存在的巨大价值需要我们去研读和挖掘。 Studying and digging teaching materials is the prerequisite and need of class. Our current teaching materials, based on the new curriculum standards, pay more attention to the close connection between mathematics and life reality, and strengthen the use of inquiry learning and hands-on learning methods, which provide ample room for the development of students’ thinking. However, the teaching materials are static The enormous value that exists in it requires us to study and dig.
