智力技能的教学是学校教学的中心任务。智力技能是借助内部言语在头脑中实现的认识活动方式。这种认知活动借助内部言语按合理的、完善的程序组织起来,并且一环扣一环,仿佛自动化地进行着。例如,学生掌握了四则运算的技能,在演算这类习题时就能运用自如地计算出答案;学生掌握了写作技能,就能根据不同性质的命题,自如地按照写作程序构思,并写出记叙文、论说文章等。 Teaching of intellectual skills is the central task of school teaching. Mental skill is the way of knowing activity that is realized in the mind through internal language. This kind of cognitive activity is organized by means of internal utterances according to reasonable and perfect procedures, and it is as if the automation is carried out.
