真实任务作为数学学习的一种资源,在激发学生数学地思维、促进学生对数学的理解、培养学生的实践能力和创新精神、使学生形成正确的数学价值观等方面具有积极的意义。在课堂教学环境下,真实任务是基于现实生活或取材于其他学科领域而设计的一种情境化学习材料。基于真实任务的数学问题解决从本质上看是一种社会文化实践活动,主要包括数学思维、数学语言、数学交流和数学态度等四个方面,这四个方面在问题解决中作为一个整体而存在。基于真实任务的数学问题解决可以为培养学生的数学素养提供一条基本途径,一种可资借鉴的参照。
As a resource of mathematics learning, the real task has positive meaning in stimulating students ’thinking in mathematics, promoting students’ understanding of mathematics, cultivating students ’practical ability and innovative spirit, and forming students’ correct mathematical values. In the context of classroom teaching, the real task is a situational learning material based on real life or from other subject areas. The solving of mathematical problems based on real tasks is essentially a kind of social and cultural practice, which mainly includes four aspects: mathematical thinking, mathematical language, mathematical exchange and mathematical attitude. These four aspects exist as a whole in problem solving . Based on the real task of mathematical problem solving can provide a basic way for students to develop their mathematical literacy, a reference for reference.
