《数学课程标准》基本理念中指出:数学课程实现“不同的人在数学上得到不同的发展。”而数学开放性教学,有利于调动学生的学习积极性;能激发学生的学习热情和研究动力;有利于学生创新精神和能力的培养,开拓其学习空间;更有利于培养学生良好的数学品质和信念,为其可持续发展乃至一生的数学学习提供素质保证。因此,开放性教学受到人们的普遍欢迎。但是可能由于教师在理解认识上的偏差,或是由于新课程标准、新课程教材本身还存在一些不足和缺陷,新课程改革中出现了一些不和谐的音符。
According to the basic idea of “Mathematics Curriculum Standard”, the mathematics curriculum realizes that “different people get different development in mathematics.” Open mathematics teaching is conducive to arousing students ’enthusiasm for learning; it can arouse students’ enthusiasm for learning and research Motivation; conducive to student innovation and ability to develop, develop their learning space; more conducive to cultivating students good mathematical quality and faith, for its sustainable development and life-long mathematics learning to provide quality assurance. Therefore, the open teaching is generally welcomed by people. However, some discordant notes may appear in the new curriculum reform due to teachers’ misunderstanding of understanding or due to the new curriculum standards. There are still some shortcomings and deficiencies in the new curriculum textbooks.
