方式是完成任务时基本的行为和认知的取向。新课标指出:学生要从单一、被动的学习方式,向多样化的学习方式转变。因此,数学教学要设计有助于自主学习、合作交流的活动,使其通过观察、操作、猜测等活动,获得数学知识,发展思维能力。学生学习的过程不是被动地吸收课本上的现成结 The way is the basic behavior and cognitive orientation of the task. The new lesson points out: Students from a single, passive learning, diversification of learning to change. Therefore, mathematics teaching should be designed to help self-learning, cooperation and exchange activities, through observation, operation, speculation and other activities, access to mathematical knowledge, development thinking ability. The process of student learning is not passively absorb the ready-made knot on the textbook
