“运算能力”是一个人重要的数学学科素养,在实际的计算教学中,算法探索是提高学生运算能力,促进抽象、推理等素养提升的重要方式与载体。教师要关注算法探索,让学生的思维活动经验呈现出自身的反思调节功能,帮助学生从经验立场走向理性思考,提升数学素养。一、关注事理合理性的存在生活事实和数学知识之间本身是一个事理到数理的转变过程,从具体到抽象的过程中让学生看到事理的意义,有合理性的存在,这是开启 “Computation ability” is an important mathematical discipline accomplishment. In actual computing teaching, the exploration of algorithms is an important way and carrier to improve students’ abilities of calculation and promotion of literacy such as abstraction and reasoning. Teachers should pay attention to the exploration of algorithms, so that students’ experience in thinking activities presents their own reflection and adjustment functions, and helps students to change their thinking from experience and to improve their mathematical literacy. First, pay attention to the existence of rational rationality between the fact of life and mathematical knowledge itself is a matter to mathematical transformation process, from the specific to the abstract process allows students to see the meaning of things, there is a reasonable existence, which is open
