“问题解决”是数学课程标准确立的四个方面的课程目标之一,其目的在于帮助学生“初步学会从数学的角度发现问题和提出问题,综合运用数学知识解决简单的实际问题,增强应用意识,提高实践能力,获得分析问题和解决问题的一些基本方法,体验解决问题方法的多样性,发展创新意识。”传统的解决问题的教学常常以“讲授—归纳─操练”为主导模式,忽视了学生的主体经验和作 “Problem solving ” is one of the four aspects of the curriculum established by the standards of mathematics curriculum. Its purpose is to help students “learn how to find problems and ask questions from a mathematical point of view, to use mathematical knowledge to solve simple practical problems, Enhance the sense of application, improve the practical ability, obtain some basic methods of analyzing and solving problems, experience the diversity of methods to solve problems, and develop the awareness of innovation. ”The traditional problem-solving teaching is often taught by“ induction-induction-drowning ” As the dominant mode, ignoring the students’ main experience and make
