计算教学中的算法多样化体现了全新的教学理念,通过让学生尝试算法多样化,用自己的方法说计算,充分展示学生的思维,让学生在相互交流中感受别人的算法,在感受算法多样性的同时,改变自己、提升自己,逐步达到理解算法的内涵,这是教师在教学过程中所追求的,也是实现学生自我建构、自我发展的途径。课程标准第一学段,《数与代数》部分是这么要求的:应重视口算,加强估算,提倡算法多样化;应减少单纯的技能性训练,避
Diversification of computational teaching algorithms embodies a new teaching philosophy, by allowing students to experiment with diverse algorithms, using their own methods that calculate, fully demonstrate the students’ thinking, so that students feel in exchange for each other’s algorithm, the feeling of diversity in algorithms At the same time, changing ourselves, improving ourselves, and gradually reaching the connotation of understanding the algorithm, is the pursuit of teachers in the teaching process, but also to achieve student self-construction, self-development. The first semester of the course standard, “Number and Algebra” part of the request is that: should be emphasized port count, strengthen the estimation, to promote the diversity of algorithms; should be reduced to purely skilled training, to avoid
