算法多样化,是《数学课程标准》所倡导的新课程中计算教学的一个新理念。在研究数的基本运算方法的同时,它要求学生形成解决问题策略的多样性,达到培养创新精神和发展思维的目的。教师在实际教学中怎样把握算法多样化的尺度呢?笔者结合本人的教学实际,及所听的部分计算教学的课例谈谈自己的看法。一、创设情境,激发、调动学生已有的计算经验,发现、探索新的算法提倡算法多样化的课堂,应该建立在让学生独立思考的基础之上,通过交流与反馈,鼓励学生对这些算法的质疑或 Diversification of algorithms is a new concept of computational teaching in the new curriculum advocated by “Math Curriculum Standards”. While studying the basic computing methods of numbers, it requires students to form a variety of strategies to solve problems and achieve the purpose of cultivating innovative spirit and developing thinking. How to grasp the diversity of scales in the actual teaching? The author combined his own teaching practice, and listening to the part of the teaching lesson to talk about their own views. First, the creation of situations to stimulate and mobilize students’ existing computing experience, discovery and exploration of new algorithms to promote the diversity of algorithms in the classroom, should be based on independent thinking of students based on the exchange and feedback to encourage students to these algorithms Question or question
