“不良经验”是原有经验对当前的学习有不良影响的,或是原有经验效率很低的。当然除了儿童的生活经验会带来不良影响,还有在以前学习中积累的学习经验,对当前的学习也会有不良影响,学生的数学学习往往是从学生已有的知识经验开始的,那也就意味着已有的“不良经验”是不可回避的。 “Bad experience ” is the original experience of the current study have an adverse effect, or the original experience is inefficient. Of course, in addition to children’s life experience will have a negative impact, as well as previous learning accumulated in the learning experience, the current study will have a negative impact on students’ mathematical learning is often from the students already had experience in knowledge, that It means that the existing “bad experience ” is unavoidable.
