心理学家盖耶认为:“谁不考虑尝试错误,不允许学生犯错误,就将错过最富成效的学习时刻.”错误是正确的先导,错误是通向成功的阶梯,学生犯错的过程应看作是一种尝试和创新的过程.在我们日常教学工作中,每天都有学生在出错.学生由于缺乏经验,产生认知偏差,出现错误后,教师往往以冷漠的表情令其坐下再想想,而不让其陈述理由.有些错误常常被忽略,学生根本没有得到任何关于正确与否的或含蓄、或直接的反馈. Psychologist Geyer said: “Whoever does not consider trying mistakes and not allowing them to make mistakes will miss the most rewarding moment of learning.” "The mistake is the right leader, the mistake is the ladder to success, the student makes a mistake Process should be seen as an attempt and innovation in our daily teaching work, students have errors every day.Students due to lack of experience, resulting in cognitive bias, the error occurs, the teacher often indifferent expression make it sit Think about it again rather than let it state its reasons.Some mistakes are often overlooked and students simply do not get any implicit or direct feedback about right or wrong.
