数学技能的掌握对学生的后续学习至关重要,基本技能的流畅性对于进一步的数学学习是必需的。但在实际教学过程中,经常存在学生技能掌握不佳的情况。笔者在大量观课和不断反思的基础上发现:在数学技能培养过程中,一些根本性的问题没有理清楚,如基本技能泛化现象、脚手架使用不当、思维定势的消极影响、训练的“质”的问题等等。本文从技能培养的认知定向、具体化模仿、言语化模仿和 Mastery of math skills is crucial to student’s subsequent learning, and fluency in basic skills is essential for further math learning. However, in the actual teaching process, students often have poor skills control. Based on a large number of lesson observation and continuous reflection, the author found that some fundamental problems such as generalization of basic skills, improper use of scaffolding, negative influence of thinking and training in training mathematical skills, “Quality ” and so on. This article from the cognitive orientation of skills development, concrete imitation, verbal imitation and
