新课标指出:学生学习应当是一个生动活泼的、主动的和富有个性的过程,学生应当有足够的时间和空间经历观察、实验、猜测、验证、推理、计算、证明等活动过程。数学学习不是简单的记忆和运用,而是应让学生经历学习过程,发展他们的创造力,促进他们的主动发展。因此,如何进行有效的教学,如何改变学生的学习方式,尤为重要。 The new curriculum standard points out: Students should be a lively, active and personalized process. Students should have enough time and space to go through the process of observation, experiment, speculation, verification, reasoning, calculation and proof. Mathematics learning is not a simple memory and use, but should allow students to go through the learning process, develop their creativity and promote their active development. Therefore, how to carry out effective teaching and how to change the learning style of students is particularly important.
