自主探究、算法多样、适当建模是《数学课程标准》所倡导的教学理念,在2 0 1 1版标准中特别提出在活动中积累经验,渗透数学思想。笔者基于小学四年级第八册数学广角《植树问题2——方阵》的课例研究提出学生在具体情景中,学生主动探究、寻求方法多样,让学生自己慢慢感悟、提炼和优化的策略,让学生的个性化学习得到充分的发挥,使得每位学生在数学学习上得到不同的发展。
Independent exploration, various algorithms and proper modeling are the teaching ideas advocated by the “Math Curriculum Standards”. In the 2001 edition of the standard, it is proposed to accumulate experience in activities and infiltrate the idea of mathematics. The author based on the eighth grade fourth grade mathematics wide-angle “tree planting problem 2-square matrix” case study put forward students in specific situations, students take the initiative to explore and seek ways to allow students to slowly sentiment, refining and optimization strategy , So that students get personalized learning fully play, making each student in math learning to achieve different development.
