新课程标准倡导通过学生的自主、合作、探究的学习方式,促进学生在“自主”中求知,在“合作”中获取,在“探究”中发展。以培养学生的自主探索能力为核心,将数学教学与学生的生活实际紧密联系起来,让学生在实际感受中激发对数学的情感,在交流与实践中探索、发现、应用新知。 The new curriculum standards promote students to seek knowledge in “autonomy ” by means of students’ autonomous, cooperative and inquiry learning styles, acquire in “cooperation ” and develop in “inquiry ”. In order to cultivate the students ’ability of independent exploration as the core, the mathematics teaching should be closely linked with the students’ actual life so that students can stimulate the emotion of mathematics in the actual experience and explore, discover and apply the new knowledge in the exchange and practice.
