现在信息社会已为大家公认,知识经济也成共识,从而培养学生的创新精神和实践能力正成为教育的重要目标。世纪交替修订的数学教学大纲和新颁布的数学课程标准都有明确的规定:“教师应……帮助他们(学生)在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能,数学思想和方法,获得广泛的数学活动的经验。”这就清楚地表明今后的数学教学必须以探究为主要方式。 At present, the information society has been recognized by all people and the knowledge economy has become a consensus. Therefore, it is becoming an important goal of education to cultivate students’ innovative spirit and practical ability. There are clear rules for the revised mathematics syllabus and the newly issued mathematics curriculum standard for the century: “Teachers should ... help them (students) to truly understand and master basic mathematical knowledge and skills in their own exploration and cooperation and exchange , Math ideas and methods, and gained extensive experience in math activities. ”This clearly shows that math teaching in the future must be based on inquiry.
