九年义务教育新课程标准指出:“有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、观察思考、自主探索合作交流是学生学习数学的重要方式”.同时新课程标准还倡导要在学生的认知发展水平和已有的知识经验基础上,创设有助于学生自主探索、独立思考探索的问题情景,促进他(她)们理解和掌握基本的数学知识、数学思想和方法,获得广泛的数学活动经验.从而发展思维,形成能力.而“数学综合与实践活动”就是旨在落实这一领域的课程目标的重要途径.中考数学对这类问题的设计突出表现在以下几个方面:一、通过观察与思考提供生动有趣的实际问题的情景(文字或图形),进行数学的思考,找到数学的模型,进而利用相关的数学知识解决问题;二、设计一个解释某
The new curriculum standard of nine-year compulsory education states: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, observation and thinking, and independent exploration of cooperation and exchange as an important way for students to learn mathematics.” Meanwhile, the new curriculum standards are also advocated Based on the level of cognitive development of students and the existing knowledge and experience, we should create situations that help students to explore independently and explore independently, and help them to understand and master basic mathematical knowledge, mathematical ideas and methods , Obtain a wide range of experience in mathematics activities in order to develop thinking, the formation of capabilities, and “mathematics synthesis and practice activities ” is an important way to implement the curriculum objectives in this field. The following aspects: First, through the observation and reflection to provide vivid and interesting practical scenarios (text or graphics), mathematical thinking, find the mathematical model, and then use the relevant mathematical knowledge to solve the problem; Second, the design of an explanation of a
