计算技能是重要的数学技能,属于心智活动技能。计算技能的发展总是从简单到复杂、从低级到高级、从具体到抽象,有层次地发展起来的。它的形成过程,一般要经历五个连续而又递进的心理阶段:认知阶段、物化阶段、外化阶段、内化阶段和熟练阶段。 Computational skills are important mathematical skills that belong to mental activity skills. The development of computing skills is always from simple to complex, from low to high, from the specific to the abstract, developed in layers. Its formation process generally goes through five consecutive and progressive mental stages: the cognitive phase, the materialized phase, the externalized phase, the internalized phase, and the skilled phase.
