《义务教育数学课程标准(2011年版)》指出:义务教育阶段数学课堂教学设计,应充分考虑本阶段学生数学学习的特点,符合学生的认知规律和心理特征,有利于激发学生的学习兴趣,引发学生的数学思考;充分考虑数学本身的特点,体现数学的实质;在呈现作为知识与技能的数学结果的同时,重视学生已有的经验,使学生体验从实际背景中抽象出数学问题、构建数学模型、寻求结果、解决问题的过程。为此,我们进行了“四步自主学习法”的课题研究,在摸索中实施“四步法”来贯穿课堂的教学实践。“四步
”Compulsory Education Mathematics Curriculum Standard (2011 Edition)“ pointed out: compulsory education phase of mathematics classroom teaching design, students should take full account of the characteristics of mathematical learning, in line with the cognitive rules and psychological characteristics of students, is conducive to stimulating students interest in learning, Trigger students ’mathematical thinking; fully consider the characteristics of mathematics itself, embody the essence of mathematics; take mathematical knowledge as a result of knowledge and skills, attach importance to students’ existing experiences, make students experience abstraction from the actual background of mathematical problems, build Mathematical model, seeking results, solving problems. To this end, we conducted a ”Four-step Autonomous Learning “ research project, in the exploration of the implementation of ”four-step method “ to run through the classroom teaching practice. ”Four steps
