《数学课程标准》明确指出:“应重视口算,加强估算,提倡算法多样化。”广大教师在新课程理念的指导下,深入研究,积极创新,促使学生经历自主探索、合作交流的学习过程,鼓励学生“创造”个性化的计算方法。因此,在我们的数学课堂中应尊重学生差异,提倡算法多样化。 “Mathematics Curriculum Standard” clearly states: “We should attach importance to port count, strengthen the estimation and promote the diversification of algorithms.” Under the guidance of the new curriculum concept, the majority of teachers, in-depth study and innovation, to promote students to learn through independent exploration, cooperation and exchange Process to encourage students to “create ” personalized calculation method. Therefore, students’ differences should be respected in our math class to promote the diversity of algorithms.
