新知探索是学生的求知阶段,是课堂教学的主环节.在这个过程中,教师的主要作用是利用有效的提问来启发学生的思路和方法,引导学生大胆猜想;而数学知识和技能的掌握则需要学生运用合理的逻辑思维、直觉思维和形象思维,通过自主、合作的探究活动来实现,从而获得新知识.新知探索可以在有效的课堂提问中展开,数学课堂提问不应是随意的,而是紧紧围绕数学课堂教学中心来进行的.美国心理学家布鲁纳曾经指出:“教学过程是一种提出问
In this process, the main role of teachers is to use effective questions to inspire students ideas and methods to guide students to bold conjecture; and mastery of mathematical knowledge and skills Students need to use reasonable logical thinking, intuitive thinking and image thinking, through independent, cooperative exploration activities to achieve, so as to obtain new knowledge.New exploration to explore in the effective classroom questions, mathematics classroom questions should not be arbitrary, and Is closely around the mathematics classroom teaching center to carry out the American psychologist Brunner once pointed out: ”teaching process is a kind of asking
