《数学课程标准》指出:“在数学教学活动中,‘错误’往往是教师在教学中和学生在学习过程中,反映在各方面,出现违反教学结论或数学方法的现象。”课堂是学生出错的地方,出错是学生的权力。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。在教学中,把学生的差错看成是难得的资源,并且加以运用,课堂也会因差错而变得有意义,有生命力。但是,真正要利用好学生的错误,不是一件容易的事。
The standard of mathematics curriculum states: “In mathematics teaching activities,” mistakes “are often the phenomenon of teachers ’teaching and students’ learning process, which are reflected in various aspects and violate teaching conclusions or mathematical methods.” Classroom is Where students make mistakes, mistakes are the power of students. Psychologist Geyer believes that: Who does not consider trying mistakes, not allowing students to make mistakes, it will miss the most productive learning moments. In teaching, the students’ mistakes as a rare resource, and be used, the classroom will also become meaningful due to errors, vitality. However, it is not an easy task to make good use of the mistakes of students.
